Next task: Generate QuickTime output for Cinelerra editing

Jason Buberel
Now that (I think) I have done as much damage as possible to the art of
creating Ogg-formatted files containing vorbis-encoded audio and
theora-encoded video (http://www.buberel.org/best.ogg) with a webcam, I
would now like to capture video + audio to a file format that can be
edited by Cinelerra.

According to the Cinelerra docs here:
http://cv.cinelerra.org/docs/cinelerra_cv_manual_en.html#SEC70

The preferred file format is QuickTime-formatted files containing
MPEG4-encoded video and MPEG4-encoded audio.

In reviewing the gstreamer documentation, I found that 'ffmux_mov'
should be able to mux those two inputs:

ffmux_mov:       audio/mpeg
ffmux_mov:                    rate: [ 8000, 96000 ]
ffmux_mov:                channels: [ 1, 2 ]
ffmux_mov:             mpegversion: 4
[snip]
ffmux_mov:       video/mpeg
ffmux_mov:                   width: [ 16, 4096 ]
ffmux_mov:                  height: [ 16, 4096 ]
ffmux_mov:               framerate: [ 0/1, 2147483647/1 ]
ffmux_mov:             mpegversion: 4
ffmux_mov:            systemstream: false

After reviewing the set of audio and video codecs, it looked like I
should be using:

ffenc_mpeg4:       video/mpeg
ffenc_mpeg4:                   width: [ 16, 4096 ]
ffenc_mpeg4:                  height: [ 16, 4096 ]
ffenc_mpeg4:               framerate: [ 0/1, 2147483647/1 ]
ffenc_mpeg4:             mpegversion: 4
ffenc_mpeg4:            systemstream: false

and for the audio there seems to be a single option:

faac:       audio/mpeg
faac:             mpegversion: { 4, 2 }
faac:                channels: [ 1, 6 ]
faac:                    rate: [ 8000, 96000 ]


But when I run a test command to validate just the audio pathway, the
file that is generated cannot be played back in xine or mplayer. The
error message produced seems to indicate that the problem is with the
quicktime file format and header information:

 > gst-launch-0.10 -v   alsasrc device="hw:1,0"  !  
audio/x-raw-int,rate=16000,channels=1,depth=16 ! faac bitrate=16000
name=aenc ! ffmux_mov name=mux ! filesink location=out.mov

See: http://www.buberel.org/qt-audio.mov

 > mplayer out.mov
Playing out.mov.

LAVF: no audio or video headers found - broken file?

The debug output from the gstreamer encoding command is:

channels=(int)1, rate=(int)16000, codec_data=(buffer)0c08

Is there something about the ffmux_mov that I am missing? There are no
options that I can give it (besides 'name').

Thanks,
jason

Hi Jason,

the ffmux_mov seems to not work well. GStreamer applied for Google Summer of
Code again and one task would be a mov muxer:
http://gstreamer.freedesktop.org/wiki/QuicktimeMP4Muxer
