6 This is an experimental build of gnash that allows the user to dump
7 both the raw (BGRA24) video stream, and the raw (PCM/Wave) audio
8 stream from a movie. The "dump gui" is disabled by default, you'd
9 need to compile it with something like this:
12 --prefix=/usr/local/gnash-dump \
13 --enable-renderer=agg \
14 --enable-gui=gtk,dump \
15 --enable-media=ffmpeg \
20 It *requires* AGG as the renderer and *FFmpeg* as the sound driver.
21 Although audio and video are separate (you can dump video, even if you
22 choose gstreamer for audio output).
24 Two new command-line parameters are available:
26 -A <file> Audio dump file (wave format)
27 -D <file> Video dump file (only valid with dump-gnash)
29 Once invoked, gnash will output sh-friendly information about the
32 $ /usr/local/gnash-dump/bin/dump-gnash -D blah.out -A \
33 blah.wav -t 85 ./sbemail45.swf
35 # Created 44100 16Mhz stereo wave file:
37 # WARNING: Gnash was told to loop the movie
38 # Gnash created a raw dump file with the following properties:
47 # Finished writing file
50 One could then play the movie with mplayer:
52 mplayer -demuxer rawvideo \
53 -rawvideo fps=12.0482:w=550:h=400:format=bgra blah.out \
56 Or play it fullscreen, with hardware acceleration:
58 mplayer -demuxer rawvideo \
59 -rawvideo fps=12.0482:w=550:h=400:format=bgra blah.out \
60 -audiofile ./blah.wav \
64 Or, convert it to YUV:
66 mplayer blah.out -vo yuv4mpeg:file=blah.yuv \
68 -rawvideo w=550:h=400:format=bgra:fps=12
70 And then make an MPEG-4/AC3 out of it:
72 mencoder blah.yuv -audiofile ./blah.wav \
74 -lavcopts vcodec=mpeg4:acodec=ac3 -o blah.avi
79 o Investigate gstreamer for audio stream capture.
80 o Let gnash send the bitmap data to places other than a file (eg, use
81 FFmpeg to encode on-the-fly).
82 o Have SDL output PCM data as fast as we can play the movie?
83 o Use something other than a polling loop for driver method.
84 o Use FFmpeg's swscale to convert AGG's RGB-only output to YUV, which
85 could then be sent to X11's XVideo extension for hardware scaling
86 (ala Adobe's Flash 9). This could be a raw X11-only gui, or an
87 add-on to the gtk gui -- much in the same way that X11-shm is
89 o Let the user specify which color space/bpp from AGG they want to
90 see (RGB24, RGB16, BGRA32, etc.).
91 o Remove gettimeofday calls so that it works on more operating
93 o Change automake to *not* include X11 libraries for the dump
94 renderer. There is no reason that this "gui" couldn't run on a
