516 tested: sig chart .png Z_BEST_COMPRESSION against Z_NO_COMPRESSION:
517 results: BEST compression for small file size & fast page reloads.
519 NOTE:
520 The new wakeup code should work equally well to wake up the volume,
521 as well as the DVB device. This is not yet completed, but may be soon.
522 Most of the code+ideas are in place to do it but the failures with the
523 DVB drivers, that have been mostly solved now, prevented further work.
524 Some work on HD3000 driver may be needed to power down cx88+or51132,
525 if closing the device is is not good enough. It should be.
527 BUGS:
528 Add a weekday timer for today after now requires config reload.
529 Moths must have flown in when trying to fix it last time around.
530 Regression testing is needed on console weekday timer addition.
532 Still tracking intermittent event/description mis-match.
533 It hasn't occurred in a few weeks. Fixed it? Keep collecting data.
535 Adding/remove event from web ui sometimes gets event wrong.
536 This one cropped up recently and not sure of the interaction yet.
537 It happened once after adding sort_pgx. Forgot to make eclean?

595 AOS hang in ts capture is fixed with better synchronization.
596 Older linuxthreads-0.10 gives diff getpid() for each thread.
597 Newer NPTL gives same getpid() for each. /bin/top is diff too.

643 --------------------------------------------------------------------------
646 1.1-rc7 20061012
647 added missing mutex inits for log and epg mutex
648 added http load/test allows for TCP-wrapper-like low-security
649 added nanosleep after pthread create in ts capture

668 ----------------------------------------------------------------------------
671 1.1-rc6 20060927
672 Peter reports this version "puts KQED-HD back on the air".
673 This may help other users that have stations sending 2 packet PMTs.
674 The ATSC spec allows it, but very few have more than 2 audios.
676 changed xine:// to mpeg:// for -w option, more generic
677 changed get sync to try to sync on a single 21 packet block
679 fixed uintodot was truncating ip:port string
680 fixed http index html does not gen zap href until 60s after modtime
682 renamed some items in tts_s to not be same as frequently used names
684 restored write_pkt, is too laggy without it, will figure flush later
686 TODO: *** DONE in 1.1-rc7 ***
687 change www_host populated from arg_whost, no need for dtv in hosts?
688 no: if machine has two different ip address, one local and
689 one remote, need to use different /etc/hosts for each client.
690 Reinstate the name and change all IP#s to name.
692 -----------------------------------------------------------------------------
695 1.1-rc5c 20060920
697 Cable testing: all scrambled but can see PAT + PMT. No MGT/VCT.
699 addded delete .tsc file when capture file is deleted
700 added select() check to fifo input loop and get sync, is broken? [WIP]
702 changed log level on load spamlist spamfile not found
703 changed parse pat and parse pmt do not check reserved bits unless -A
706 fixed F: missing from getopt, -F[1...5] did not work
707 fixed parse pmt needs to make separate pmt payloads for each vc
709 fixed test packet falls to test mpeg2, doesnt check table/psi=1
710 fixed parse pmt was breaking KQED-HD (post 8pm) with 2 packet PMT
711 KQED-HD is still partly broken with 1.1-rc5a-c, but it
712 seems to be xine player not liking the 2 packet PMT, too.
714 todos from -rc4 moved forward
716 -----------------------------------------------------------------------------
718 1.1-rc4 20060913
720 audit fifo; valgrind errors; man gcc -fstack-check for multithreaded;
721 comp.os.unix.programming mentions signals need sa_mask init.
722 -fstack-check causes it to crash in asnprintf? odd.
724 audited fifo code, found one wrong fallthrough when 0 read return
725 audited fifo again, reduced number of pthread yields
726 audited asnprintf calls, found a few missing parameters
727 audited dvrlog calls, found a few missing parameters
729 added test clock res to find most accurate clock
730 added sa_mask init to emptyset for signal init
731 added load volatile yearmmdd:hh:mm:lm:name format, save is still uts
733 changed AOS back to 9 tries for wobbly stations
734 changed find stations runs automatically if no config
735 changed find stations uses Dxx for SID, old station # tupari request
736 changed parse tvct tries harder to get callsign, not "i", paxson.
737 changed frames sequences to use differential for smaller data type
739 fixed WHO macro to stop gcc 3.4 from complaining
740 fixed the mutex variables so gcc doesn't complain anymore.
741 fixed dvrlog init removed, let dvrlog handle it.
742 fixed rip van winkle bug that was killing main thread. bad stack.
745 **** TODO **** DONE (back to around 21m resident instead of 30m)
746 6h of frames and sequences should require just under 3mb of ram.
748 frames and sequences array memory redux:
749 frames can be 16 bit, using 2 bytes instead of 8:
750 16:15 frame type 01-03, 00 is invalid
751 14:0 1-16383 packets since last frame, 0 is invalid
752 Since this is largest list it will show biggest reduction.
753 0 or -1 can mark end of list.
755 sequences is reduced from 8 to 4 bytes:
756 32:0 bytes since last sequence
758 output can save in current format for xtscut and hexdump
760 ----------------------------------------------------------------------------
763 1.1-rc3a 20060905
765 added help on setting up for user mode to quickstart part 3
766 added defines near top for browser colors so user can change easily
768 changed sequence/frame allocation to reduce gcc pre-processor load
769 increased cap log to 12hr limit with same for sequences, frames
771 fixed wrong cap stat range check in show/dump cap log/test pkt stats
772 fixed -b allows long info cap. timer start should kick it out
773 fixed add current event while info cap doesn't start event
776 *** DONE ******* TO DO *************** all but last done in 1.1rc4
777 last done in 1.1rc9
779 TODO Find why main thread is croaking, yet capture threads keep going.
780 This is the AOS#4 hang, aka Rip van Winkle sleeping bug.
781 It's still capturing but the console is dead.
782 Problem was dvrlog/asnprintf stray parameters not getting checked.
783 This caused stack to pop wrong values in main thread. Whoops.
784 Use dummy asnprintf/dvrlog to help compiler find too many/few parms.
786 DONE find stations should check first letter for K or W match
787 and try next VC name until it finds one with K or W first char
788 KBPX Boston PAX network has this problem. "i" is first VC name.
789 DONE.
791 TODO? EPG generated in RAM only except for save at end of capture.
792 Reason again?
797 ---------------------------------------------------------------------------
798 1.1-rc2 20060827
800 added table of contents, moved http config to quickstart
801 added http response send support for ram epg update [WIP]
802 added http start stores MTU as wss->mtu for http response
803 added [m] key to show vct for MPEG PAT/PMT display toggle
805 changed help to reflect correct netmask usage
806 changed allow 127.x.x.x ip address for -w option
807 changed -W -R exit with error if screen is not executable
808 changed find stations to 45% signal threshold
809 changed http response to use wss->mtu for output byte count
810 changed ts capture loop to stop waiting when thread pidi/o cleared
812 disabled low QoS auto-zapper. It needs more work.
814 fixed -W exits with error message if GNU screen not found
815 fixed parse www bind to generate correct netmask
816 fixed call to http test netmask, wrong address was used
817 fixed http auto epg set wrong pgto value, was 180 now 10800
820 TODO
822 DONE tupari reports he can't bind to loopback. Removed 127.x.x.x check.
824 DONE tupari reports -W does not give error when screen not found.
825 Also observed here is that -W crashes on capture start, and gdb
826 is not very helpful in this scenario. No screen exits atscap now.
828 DONE tupari reports find stations ch15 bogus detects and hangs. He also
829 reported a freeze and hard lock on kill. killall might fix lockup,
830 but still need more data to see if freeze is same one I've seen:
832 The wall clock works but the capture clock doesn't. Low AOS?
834 If I recall, testing was showing input thread dying but the
835 output thread and parent thread were still running, but there
836 is code in both loops to check cap now being cleared. Join order?
838 *** TODO audit other strength checks
840 DONE Test MTU > 7200 for r8169 1g enet. Test failed. Back to 7200.
841 I guess the driver notes weren't kidding. Over 7200 is broken.
843 DONE Testing is underway with intentionally bad antenna positions
844 to see if the freeze is related to driver failure. The normal
845 observed scenario is DVB-API returns junk packets and everything
846 keeps going even if it's all being marked as junk.
849 ------------------------------------------------------------------------------
851 1.1-rc1 20060815 sent to tupari, haven't heard from rc0 recipients yet

861 changed show cap status sets timer status T_DONE if below 50% QoS
862 changed show timers removes timer with T_DONE status
863 changed show channels signals gives avg before moving to next channel
864 changed delete order, ts file last makes html refresh remove log href
865 changed http log uses dvrlog, trunc NL (chg for full request/response)
866 changed http del timer checks program number, too
867 changed epg refresh time by a few seconds to spread the load around
868 changed epg current event field to 255 char limit
870 fixed http reload epg does not work when timer list is empty
871 fixed no delete href for spam event with timer in future
872 fixed no end-of-cap QOS/AOS fail status because delete timer reset it
873 fixed endless loop on search volatile timer that has failed AOS
874 fixed add/remove search doesn't erase timer0 if timer0 match is active
875 fixed -x, extra : in getopt whoops, 1.1-rc0 use -x0 -x1 workaround
876 fixed http version number parsed incorrectly
879 TESTME dump cap log event name/description audit. Observed stale data.
881 TESTME Proxy http failure, no imgs, may be related to keep alive fail.
883 DONE Cap transfer stops on signal-dropout and hangs cap, zap still worked,
884 but show cap stats should catch QoS low and abort the capture.
885 Not sure if cap stats clock was still updating. Will test more.
886 The auto-zapper is working better now, maybe too agressive on zap.
888 DONE Endless loop on search volatile timer that has failed AOS, for
889 the same reason delete volatile search timer puts back on list.
890 See if lzpgt can be used to prevent endless loop.
891 Problem was out of order logical sequence for delete and lzpgt.
893 DONE Web epg event date more than 16 days old will give full date.
894 This is for stations that stop updating their guides, like KTBU.
896 DONE Channel scan gives avg on last ch loop, instead of possible bogus
898 DONE Log existing adds href to build stats html even for EPG
899 have to change build outnames to pg/EPGch.html
901 NO Merge colors/filters legend? The fields have nearly the same meaning.
903 IDEA FOR FUTURE
904 noticed KHOU has wide variety of spam. add st to spamlist to
905 track last start time seen. add age-out to remove items >30-day old
906 load spamlist is where the age filter should be.
908 ------------------------------------------------------------------------------

930 changed capture log and capture stats html-ized, fixups to html epg
931 changed ordering of some functions to reduce prototype count
932 changed abstract save guide into save vct and save epg
933 changed abstract load guide into load vct and load epg
934 changed build outnames @ flag tries to use start time then current
935 changed # as timer date flag to @ so it works as a URI
936 changed test spam compare optimization to reduce cpu loading
937 changed show event short does not call build pg epg, moved to parse eit
938 changed dump guides and build html head for multiple instances
939 changed multiple web servers for multiple instances
940 changed web server still sluggish: nanosleep after connect removed
941 changed test config to look for spamlist timeout
942 changed spamlist to global /etc/atscap/atscap.spam, removed cfg 'S'
943 changed parse stt logging but rest looks ok? what about KHCW drift?
944 changed dump guides to reflect server ip:port that dumped guide
945 changed fifo write tries more times, optioned out multi-stage tries
946 changed file redux, .tsx now has same data as .tss .tsf output had
947 changed atomic_ to fifo_atomic_ to give the functions a better name
948 changed html program guide cosmetic cleanups, added rating text
949 changed video + audio pid counts valid after VCT or PMT received
950 changed capture log starts at current minute when first invoked
951 changed EPG display starts at current event program when first invoked
952 changed EPG [ENTER] adds current event matching program # if set
953 changed build outnames to allow program number > 7 for cable
954 changed [TAB] disabled for cable, not needed, channel scroll avoidance
955 changed colors in show virtual channels: red indicates missing data
956 changed get_timer_add weekday timer program # to allow > 7 for cable
958 fixed old bug: stop capture if adding current timer during info cap
959 fixed move timers find search event index returns wrong counter
960 fixed add event timer from epg did not copy program # to timer
961 fixed volatile timers from EPG search event loses event descriptions
962 fixed find timer epg works better, but still no fuzzy start/len yet
963 fixed word wrap, forgot to print char after nl/indent
964 fixed timer start time correct but not refreshed after volatile expires
965 fixed add search during info cap doesn't start search event if current
966 fixed delete search event should redraw timer list from top
967 fixed build outnames timer [KUHT].1 audio# wrong after timer [KHCW].3,1
968 fixed search timer overlap kept writing to same file, ignored new name
969 fixed save config after ts cap to retain any found search timers
970 fixed epg_name memset() overflow wiping FIFO pointer and structure
971 fixed [z]ap did not zap the current capture, but did zap .ts[f,s,l]
973 fixed load config restores current channel to avoid guide corruption
974 fixed load config+guide while cap adds search match on wrong channel
975 fixed search timer hold down at end of timer to prevent event truncate
976 fixed? show virtual channels selected program gets colors wrong
977 fixed? [d]elete timer put search timer back on list, endless loop
979 removed delete code for .txt .tss .tsf files, using .html/.tsx now
980 removed EPG sort since EIT sort is working for KRIV FOX now
982 replaced syslog with dvrlog; html build snprintf with asnprintf
984 BUGLIST:
985 Stopping a timer with [o] override then BKSP does not remove the timer,
986 or does not set the hold down for a deleted timer. Web ui seems ok,
987 since it actually removes the timer, but still testing.
989 build outnames now overrides vc to 0 if find vc pgm fails, but it
990 FIXME:* SHOULD hold down output until cap vc set from cap pn + PAT/PMT info.
993 TODO scratchpad
995 Need html pages for Master Guide and Virtual channels. Put hrefs
996 for them in html stats page in the atsc transport table area.
998 Finish breaking down dumps to build and dump for dynamic update to
999 serve created page from mem in addition to the current file method.
1001 TODO? html interface has no href for full capture, but room for href
1002 right of reload href. Full capture ability might be useful,
1003 There is always the console interface for full capture if needed.
1005 TESTME scratchpad
1007 Adding current event via [enter] sometimes screws up search timers
1008 by moving search timer to top of timer list, above valid timers.
1009 I think it's fixed but still testing. It's related to EPG filters.
1011 UDP xine seems to play a little bit too fast. Maybe it's dropping
1012 frames and then getting ahead and having to wait. Still testing.
1013 TCP playback is fine, because xine reads as fast as it wants,
1014 without being constrained to actual data rate from the card.
1016 http file not found is not working properly.
1017 does not return 404 as it should instead of hanging user agent
1019 -x seems broken, of all things. How did that happen?
1020 Currently having to hard code arg_extras = ~0;
1023 TESTME Goal is to go from atscap -S to web browser, without using
1024 console beyond starting atscap -w or a script to do same.
1026 None of the web pages are dynamic in RAM-only. Should they be,
1027 rather than take the cpu cycle hit of file create?
1029 Current method is to write the channel.html file to /dtv/pg/,
1030 and it does seem to introduce enough load to be noticeable
1031 as a stall during playback when the guide create occurs.
1033 Yet another thread and socket for server to server communication.
1034 No need for it so far, but thinking about how it could be useful.
1035 Current method seems to work well enough for now.
1037 Rearrange console with timer name before start time. This is
1038 to make it easier for console user to tell which timer# to delete.
1040 Fix KQED not capturing program #1: atscut has -kmgt broken samples
1041 might be fixed with build outnames and program select rework?
1042 Have WB with swapped PMT's in PAT to test against now.
1043 Still on list of things to test.

1250 tested dvb status check against hg/CVS v4l-dvb and immediately backed
1251 it out because it is a design idea only for sat tuners. Not ATSC,
1252 so DVB FE_TUNE_MODE_ONESHOT ioctl disables this function now.
1254 tested .tsf .tss files for identity with atscut 0.9.5 .tsf .tss files
1255 these files are structures therefore architechture dependent.
1256 ergo, they are not transportable between little and big endian,
1257 but can easily generate by atscut -s compiled on the target.
1259 tested KRIV + KPRC ETT increasing: ETT Version change is non-compliant.
1260 TODO it would be informative if version change was visible in MGT.
1262 tested with old V4L drivers on 2.4.26. Works as well as it can.
1263 See comments near top for the reasons why V4L is sub-optimal,
1264 and why you should upgrade to DVB API at soonest opportunity.
1266 tweaked ATSC STT set system time method, trying to fix wobble
1268 updated comments to reflect new DVB API testing and results.
1269 Things are finally robust with correct DVB API settings.

1488 Notes for 1.0-rc7 release:
1489 Lots of extra details to see and not a few bugfixes.
1491 Should be more compliant with ATSC specifications in regards
1492 to handling stations that stop sending PSIP and revert to MPEG only.
1494 [v] key VCT selection now works with VCT and PAT+PMT, so you
1495 may use timername.pgm even when PAT+PMT are only tables seen.
1497 Should also be more compliant with ATSC specifications in regards
1498 to handling Huffman text decompression. A/65b says 'must' support, so
1499 this code does it whenever mss text comp=1 or 2. (KPXB fix)
1501 Timer start or stop should kick any of the guides back to the
1502 timer list so you can see what is being done and any errors.

1555 changed event status (bottom left) to be more descriptive
1557 added range to get pgm timer add
1558 added set virtual channel from vct
1559 added function keys: arrows and edit keys for scrolling
1560 added get timer reschedule with range for manual pre-empt reschedule
1561 added find last program to set guide file mtime for guide age out
1562 added build tvct text, removed duplicates from test vct, faster now
1563 added hotkey to channel checks for saved program guide and loads it
1564 added save and load guide for each station, with guide text dump
1565 added info cap checks some conditions to time out guide load
1566 added attempts to auto-correct if MGT version stays 0xFF
1567 added MPEG2 adaptation field test for MPEG2 payload handling
1568 added -l logs bad CRC that slipped past TEI check. short packets wtf
1569 added -S scans for signals and optionally builds a crude config file
1570 added more detail to show vct and made it scrollable for cable
1571 added more detail to show mgt and made it scrollable for cable
1572 added audio select to show vct for manual select but not in timers yet
1573 added 'r'eque for non-cap mode to manually reschedule pre-empted events
1574 added FILE_PERMS from user request to set permissions mode to 0666
1575 added timer duplicate remove load/pgm timer add, but user can still set
1576 moved cap stats data collection to fifo output loop to avoid dropouts
1578 renamed test_ to parse_ where it actually parses stream
1579 reduced aos to bare minimum code at start of capture
1581 Notes for 1.0-rc6 release:
1582 Most of the clunk has been fixed but some remains in VC select.
1583 Have to select [c] before you can select [a], or manual first-VC cap.
1585 Biggest UI improvement is arrow keys and pg up/dn keys work now,
1586 but you still have =[]' scroll keys in case you have chiclet keyboard.
1588 NOTE: signal scan being enabled will slow down timer scroll.
1590 All the screens are scrollable now, except channel list, including
1591 MGT and VCT lists that are also more detailed in the descriptions.
1592 MGT also shows live update of the tables during capture.
1594 Still a few quirks, but no segfaults.
1596 TODO DONE
1597 Only things left to do before I'm completely happy with it:
1598 Automatic guide load ( [l] key is manual full guide load )
1599 Automatic event reschedule ( [r] or [c] key is manual reschedule )
1600 Audio select for timers by name ( [v] [c] X [a] Y is manual select
1601 where X is VC# and Y is Audio ES# within stream. Real CLUNKY! )
1603 These three may not be done before -rc6 goes out. The logic puzzles.
1605 Released to the wild. Bad bugs discovered after release:
1606 [z] zap immediately on cap start makes dump cap stats go nuts
1607 [p] program guide does not exit as claimed when timer starts
1609 -------------------------------------------------------------------------------
1611 1.0-rc5 20050314
1612 fixed show cap stats at start of cap giving stale values until update
1613 fixed output redux one shot on status change or status color change
1614 fixed test sync/packet to check the 21st packet when alignment is 0
1615 fixed alignment problem after X restart and buffer overrun. doh!
1617 changed [ENTER] now caps first valid VC. use \ for full ATSC cap
1618 changed FIFO align method, HD2000 handles X restarts without desync
1619 changed 'p' SNR display key to 'w', 'p' now for Program Guide!
1620 changed key signal scan toggle is now channel hotkey
1621 changed cap time display uses easier to read colors for digits
1622 changed SECOL to timer->secdt: calc secdt early end for timer BROKEN
1623 changed check timers to start 3 seconds early for longer AOS check
1624 changed fifo full does not exit: logs and sets cap fail type now
1625 changed card ID display to reflect card type+dtv# and V4L level
1626 changed ts cap goes to timer display when cap starts, to get user attn
1627 changed last file out status indicates reason for fail, if not ok
1628 changed in-program help screen to reflect new keys and colorized
1629 changed all float to double
1630 changed dump cap stats:
1631 use packet test code instead of custom driver vague LED check:
1632 added detailed stats about the stream for error determination
1633 changed indication of transport error severity per second
1634 appends to /var/log/dtv[0-3], no more *.stat file
1635 moved from -l option back to default scope, seems useful now
1636 changed show cap stats:
1637 more informative error stats during capture
1639 changed driver again (optional via -x):
1640 HD2000:
1641 signal scan split to v4l1:v4l2 code:
1642 v4l1 faster, near 38 scans/second, makes -x LED update faster
1643 NOTE: v4l1 gives RS indicator on strong sig where V4L2 doesn't
1644 v4l2 method copies faster HD3000 method, w/o Rx Status AGC flag
1645 v4l2 is slower than v4l1 but gives less vary in signal value
1646 HD3000:
1647 cx88-atsc.c changed:
1648 changed Receiver Status timeout delay to 4 instead of 3
1649 trying to get rid of occasional 55% getsigstr val lockup
1651 removed jivo and all gtk code. try a different method. maybe freevo.
1652 removed custom driver cap test LED code, test packet works better
1653 removed vary display. 's' & dump cap stats gives detailed reports.
1655 moved show KB LED status under -x scope, but still fakes for HD3000
1657 added ATSC and MPEG parsing. Bugs still exist:
1658 afc3 payload not parsed. No afc2 found in local streams.
1659 afc1 payloads handled well enough, but memcpy more than needed.
1660 This maybe affects statistics, short-changes a few error counts.
1662 added volatile timers to load save cfg to keep program guide selections
1663 added keys 'v' VCT 'g' MGT 'p' EIT/ETT Program Guide!
1664 added 's' key stream detail display to show every packet stat counted
1665 added 'e' key for elapsed/user time toggle, for how long timer has run
1666 added -r replay file mode, dummy mode, read parm or dummy.ts
1667 added -k Klutz-Guardo console input disable, keeps fatfingers away
1668 added -A option to set system time from stream time:
1669 this does not currently work right because:
1670 local stations do not synchronize to the same time.
1671 added signal scan time quantified for aos 120 tries or 4 seconds
1672 added volume has no space error should terminate the program:
1673 FIXME: it's broken, doesn't terminate.
1674 added one shot timer redraw of color status change in next 24 hours
1675 added cap fail status abbreviations to indicate why cap failed
1676 added lltoasc to display large vals w/ commas; strdup=free after use
1677 added CRC32 function for ATSC tables from atscut.c. More robust now!
1678 added VC PID to vc[] and test mpeg packet for stream splitting
1680 audited timer total and space calc to verify correct display:
1681 It looks wrong, if you don't realize programs set to overwrite
1682 calc as a single length. Shows with $ or # calc multiple lengths.
1683 So no moth here, only the limits on how programs counted.
1685 Released to the wild.
1687 UPDATE: whoops, too early it seems, since it's buggy and clunky.
1689 -------------------------------------------------------------------------------
1691 1.0-rc4 20050117
1692 rewrote get sync, old method was obtuse and not robust, missed shows!
1693 caused: added test sync for sync error and minimal transport check
1694 fixed override timer to remove/reschedule the overridden timer
1695 fixed CLI -s load cfg, -s has 1 non option chan arg, -s no stdin
1696 fixed CLI find cfg parse of -c arg cfg path
1697 changed console scan to allow more UI during cap, disabled for -s
1698 changed show cap stats, updates timer list, finally
1699 changed 'k' keep to 'o' override timer
1700 changed jivo to show one signal bar instead of all [WIP]
1701 changed timer cap sets sets scan channel to next timer chan
1702 changed add/delete timer saves timer config, change/reset timer doesn't
1703 removed V4L2 signal strength from V4L1 driver return and parse
1704 moved SCHED FIFO before sync check to prevent buffer overruns
1705 moved dump cap stat to be within -l scope
1706 added close/open device at end of cap to prevent last buffer overrun
1707 added test packet for use by test sync and fifo output minimal check
1708 added more one shots to reduce excessive calls, from gprof analysis
1709 added 'c' change timer, adjusts running or queued timers [WIP]
1710 added test sync to fifo output loop. stream monitor, no editing
1711 added header line for capture status superfluous blinky lights
1712 added for multicard: 'm' moves timer from current cfg to another,
1713 caused: changed move timer and save cfg ignores timers w/o day bit
1714 changed load cfg to not reset/load temp timers w/o day bit
1715 testing:
1716 2.6.7: ok for both HD2000 and HD3000 V4L1, partial V4L2
1717 2.4.26: ok for HD2000, but kernel issues with HD3000 module load.
1718 I don't have HD3000 working yet on 2.4.26, HD2000 is ok,
1719 but if you do, pchdtvr should see it and use it.
1721 -------------------------------------------------------------------------------
1723 1.0-rc3 20041230
1724 fixed 't' timer, 'd' delete, resets tsvc/vt & fixed prompt + headers
1725 fixed -t only disables initial timer load, not all future loads
1726 fixed sig scan always shows NLK after 'x' clear
1727 fixed empty timer list prompt in wrong place at wrong time
1728 fixed user req: variable len callsign and net id.
1729 fixed jivo to work with latest cosmetics
1730 changed top left 0,0 displays version+email then last cap status
1731 changed dump cap stats to show fileout from filein, 1 line w/o -x
1732 changed kb LEDs need -x, as falls under hd2000 extras category
1733 changed blank virtual LED indicators when scan off
1734 changed manual cap is green, timer cap is red
1735 changed some commentary updated to current methods
1736 added preliminary V4L2 API, seems broken or know how to use issues
1737 tested with linux kernel 2.6.10: made driver 1.5 suspend/resume nop
1740 1.0-rc2 20041224
1741 fixed jivo for use with stock driver. forgot to test it -rc1. sorry :>
1742 added commentary segmentation to gtk refresh. ordering needs work.
1743 added -t to not load timers when config file loaded, for those days
1744 when antenna tests are more fun than watching re-runs.
1745 added error msg to alert which config file could not be found
1747 2 card, HD2000 + HD3000, testing 1.5 drivers, so far looks GREAT!
1748 I doubt my machine can test 4 cards to a single hard drive.
1749 But I might get another hard drive and let you know.
1750 UPDATE 2005-Jan-17: works fine, 4 cards to single drive. WHEE!
1752 -------------------------------------------------------------------------------
1754 1.0-rc1 20041222
1755 fixed deleting last timer on list left timer on console, now erased
1756 fixed timer headers always display when in timer screen
1757 removed args for channels, uses config file Cx lines instead now
1758 removed all (19+) -2/+2 chanadj by adding 0,1 to ptc[],
1759 audited snprintf and strncpy to use sizeof(dest)-1 where needed
1760 changed load/save config: 'Tx' timerlist 'Cx' scanlist channels
1761 changed key for clear timers to '~' to reduce accidents
1762 changed key for input config to '|' to reduce accidents
1763 changed key for config write to '+' to reduce accidents
1764 changed cap leds allocation to 8 hours
1765 added device autodetect, autoconfig select, can still override with -i
1766 added card# to log display and console header display
1767 added strength & peak to 'x' clear
1769 Send to Jack & Rusty after verifying against unmodified 1.5 driver,
1770 and against my patches for instrumentation. All works ok so far.
1772 -------------------------------------------------------------------------------
1773 pchdtvr - on the road to 1.0
1775 pre9-1.0 20041220
1776 removed fine tune setting and keys because no observed benefit to ATSC
1777 changed -i to take numeric (0-3) or /dev/dtv# argument
1778 changed default config file to /etc/pchdtvr.0.conf: 0 = card #
1779 changed signal strength display to simplify, use 'p' to cycle extras
1780 changes to variables and text to reflect SNR/AGC instead of post/pre-EQ
1781 added multi-card support: HD3000 + HD2000; finally got my HD3000s!
1782 added -x optional instrumentation support video_signal.aux extension
1783 added to get signal lock: more conditionals for HD3000 signal support
1786 pre8-1.0 20041213
1787 changes to match instrumentation driver video_signal.aux extension
1788 changed aos log format to show decimal % of signal strength
1789 added use of VIDIOCGCAP to set is_hd2k based on device name
1790 added preliminary HD3000 support via conditional is_hd2k
1793 pre7-1.0 20041108
1794 changed timer/free status, add space to end to get rid of ))
1795 changed fileout name status, remove path
1798 pre6-1.0 20041026
1799 changed RMS log for AGC, removed avg
1800 changed file remove log to reflect user zap vs automatic delete
1801 changed compile info at top because someone reported needing -lm
1802 changed console exit to not remove renamed
1805 pre5-1.0 20040913 Are you ready for some football?
1806 NFL fix, added 'k' to switch capture to manual mode for game overrun
1809 pre4-1.0 20040902
1810 cap fails sometimes: collect/log AOS data for all 15 tuning attempts
1811 log format: Bb, repeated 15 times, for 30 chars
1812 B is high nyb of post, 0-A is bad, B C D E are in good signal range
1813 b is . no error, E RS fail, L lock fail, X both
1815 creates .stat signal log file for each cap, ~78 bytes per minute of cap
1816 file is created at end of capture, with summary lock/error info.
1819 pre3-1.0 20040822
1820 better indication of no lock reason in signal scan.
1821 jivo checks DISPLAY envar being set before checking for gtk.
1824 pre2-1.0 20040820
1825 CAP LED blinks during capture, cycle is 2 seconds.
1826 NUM LED echoes green Lock LED, cap once per second, more during scan.
1827 SCR LED echoes red Error LED, cap once per second, more during scan.
1828 jivo reflects err on status line to indicate red Error LED.
1830 keyboard LEDs use more flexible console ioctl instead of VT ESC codes.
1831 You will not have any LED control if you start from X,
1832 but it's only for knowing what console is doing, without
1833 having to actually switch to it to see what it's doing.
1835 NOTE: 'reset' if your LEDs don't respond to respective keys.
1838 pre1-1.0 20040819
1839 Changes to get it ready for 1.0:
1840 Error and Carrier LED indicators in console, scan or capture.
1841 Capture abort if Error LED on too long (TESTME:)
1842 Compiles and works the same on gcc2/kernel2.4 and gcc3/k2.6,
1843 hopefully, using the drivers you will find at:
1844 http://www.nop.org/inkling/dtv/kernel/ *-pchdtvr.tgz
1848 0.9z-pre1-1.0 20040525-20040817
1849 minor tweaks, keys & help & usage, default capture dir is . now.
1850 changed -c to be config path and -s to be capture seconds, makes sense.
1852 0.9z is the candidate for 1.0, but GTK2 issues, i.e. crashes if X does.
1853 Recover from X crash/kill somehow via msg, signal, whatever so
1854 GTK2 panel can be shut down properly and not crash console.
1855 (Update: NOT GOING TO BE DONE. It seems IMPOSSIBLE to do, too.)
1857 Final console issue before 1.0-pre is No Carrier or Reed Solomon Error
1858 should cause the capture to abort, rather than capture bad stream.
1859 Abort should happen only if Error is set for at least one minute.
1861 NOTE:
1862 X fault-tolerant GTK2 panel restart is a dead end for now.
1864 Recovery scrapped because recovering from X death seems impossible.
1865 Trapping SIGPIPE on X terminate did help, but not much. Without a
1866 method to de-alloc and re-init GTK2 structures, fault-tolerant
1867 gtk panel looks hopeless, or I'm not imaginative enough.
1869 -------------------------------------------------------------------------------
1870 pchdtvr - a bunch of silly stuff trying to find road to 1.0
1872 0.9z 20040525 add scan fine tune keys: - -125kc , = +125kc, 0 reset, useful?
