Dumping processing tools manual

1 Concatenating dumps

Concatenation of dump files is concatenation of their contents. 
So cat and similar tools can be used to concatenate dumps.

2 audiotodump.exe

Converts raw PCM audio to dump file containing said audio as PCM 
audio track.

Syntax: audiotodump.exe <options> <input> <stream> <output>

Convert raw PCM audio from file <input> to dump named <output>. 
The audio data is placed as PCM-type stream named <stream>.

2.1 Options

2.1.1 --8bit

Assume that samples in file are 8 bits per channel.

2.1.2 --16bit

See --16bit-little-endian

2.1.3 --16bit-little-endian

Assume that sample in file are 16 bits per channel and 
little-endian. This is the default.

2.1.4 --16bit-big-endian

Assume that sample in file are 16 bits per channel and 
big-endian.

2.1.5 --mono

Assume that samples in file have only one channel.

2.1.6 --stereo

Assume that samples in file have two channels in order left, 
right, left, right,... This is the default.

2.1.7 --stereo-swapped

Assume that samples in file have two channels in order right, 
left, right, left...

2.1.8 --signed

Assume that samples in file are signed. This is the default.

2.1.9 --unsigned

Assume that samples in file are unsigned.

2.1.10 --rate=<rate>

Assume that sampling rate in input file is <rate> Hz.

2.1.11 --volume=<left>,<right>

Write initial volume <left> for left channel and <right> for 
right channel to output.

2.1.12 --volume=<volume>

Write initial volume <volume> for both channels to output.

3 cutdump.exe

Copies section out of the dump.

syntax: cutdump.exe <input> <start> <end> <output>

Cuts section <start> to <end> from dump <input> and saves it to 
<output>.

<start> and <end> are specified in nanoseconds if these don't 
contain '.'. Otherwise these are assumed to be in seconds. So for 
example both 100000000 and 0.1 signifies 0.1s point.

4 demuxdump.exe

Copies stream out of the dump.

syntax: demuxdump.exe <input> <stream> <output>

Cuts stream <stream> from dump <input> and saves it to <output>.

5 dumpconvert.exe

The main dump to other formats converter.

syntax: dumpconvert.exe <options> [<subtitle options>...] [<audio 
options>...] <files>...

Convert <files>... into other formats. Note that this tool takes 
subtitle and audio options (and that they are shared with 
playdump.exe).

5.1 Options

5.1.1 --video-width=<width>

Set video output width to <width>. No default, must be specified.

5.1.2 --video-height=<height>

Set video output height to <height>. No default, must be 
specified.

5.1.3 --video-framerate=<fps>

Set video output fps to <fps>. <fps> can also be 'auto' to allow 
variable-framerate output. Default is fixed 60fps.

5.1.4 --video-scale-algo=<algo>

Set video scaling algorithm to <algo>. Currently following 
algorithms are available:

• 'nearest' (nearest neighbor)

• 'average' (weighted average of covered pixels)

• 'lanczos1', 'lanczos2', 'lanczos3', 'lanczos4', 'lanczos5' 
  (higher-quality resizeers).

5.1.5 --video-scale-algo=”<algo> <width> <height>”

Set video scaling algorithm to <algo> for frames that are <width> 
by <height> (i.e. set special scaler for specific resolution).

5.1.6 --video-max-dedup=<dedup>

Allow up to <dedup> consequtive frames to be elided if they are 
indentical to previous (truly identical, not just “identical”). 
Requires variable framerate output.

5.1.7 --audio-delay=<delay>

Delay audio by <delay> nanoseconds/seconds (seconds if <delay> 
has '.', nanoseconds otherwise). Delay may be negative.

5.1.8 --subtitle-delay=<delay>

Delay subtitles by <delay> nanoseconds/seconds (seconds if 
<delay> has '.', nanoseconds otherwise). Delay may be negative.

5.1.9 --output-<format>=<filename>[,<parameters>]

Output to <filename> in format <format>. <parameters> is 
format-dependent parameters.

5.2 Output formats

5.2.1 oggenc

syntax: 
--output-oggenc=<filename>[,<oggenc-option>[,<oggenc-option[...]]]

Pipe audio to oggenc in order to encode OGG Vorbis to <filename>. 
Note that audio bitrate and format is automatically set 
correctly. For oggenc options in form --foo=bar, use foo=bar as 
<oggenc-option>. For oggenc options of form --baz, use baz as 
<oggenc-option>

5.2.2 rawaudio

syntax: --output-rawaudio=<filename>

Write 16-bit stereo little-endian signed audio track in raw 
format to <filename>.

5.2.3 rawi420

syntax: --output-rawi420=<filename>

Write video in raw I420 format to <filename>

5.2.4 rawi420-uvswap

syntax: --output-rawi420-uvswap=<filename>

swapped.

syntax: --output-rawrgbx=<filename>

Write video in raw RGBx format to <filename>.

5.2.6 timecodev2

syntax: --output-timecodev2=<filename>

Write video timestamp data in v2 format to <filename>. Very 
useful for automatic-/variable-fps encoding.

5.2.7 wav

syntax: --output-wav=<filename>

Write audio in wav form to <filename>. Note that files with over 
1 billion samples are not written properly.

5.2.8 x264

syntax: 
--output-x264=<filename>[,<x264-option>[,<x264-option[...]]]

Pipe video to x264 in order to encode h.264 to <filename>. Note 
that video size is automatically set correctly. For x264 options 
in form --foo bar, use foo=bar as <x264-option>. For x264 options 
of form --baz, use baz as <x264-option>. 

BUG: Framerate is not set correctly automatically.

44100Hz). Note that this command accepts audio and subtitle 
options.

13 Audio processing options

Audio processing has three stages:

• Per-stream premix filtering

• Mixing

• Postmix filtering.

For each, the operations are done in order they are given on 
command line. If <stream> is specified for some operation, it 
occurs as part of premix filtering for that stream. Otherwise it 
occurs as postmix filtering.

13.1 --audio-mixer-filter=[<stream>:]<a0>,<a1>,...

in order of increasing delay.

13.2 --audio-mixer-filter=[<stream>:]<a0>,<a1>,...;<b0>,<b1>,...

output coefficients <b0>, <b1>,... given in order of increasing 
delay.

13.3 --audio-mixer-gain=[<stream>:]<gain>

Amplify signal by <gain> dB.

14 Subtitle processing options

Subtitle option of form foo=bar is given as 
--video-hardsub-foo=bar on command line and as foo=bar in script

--video-hardsub-baz and baz. Options are processed in order they 
are encountered, script files are processed immediately when 
script file option is encountered.
