muxing streams

Hi all!
I have extracted the video and audio streams from a matroska file getting: mkv.0: JVT NAL sequence, H.264 video @ L 31 mkv.1: ATSC A/52 aka AC-3 aka Dolby Digital stream, 48 kHz,, complete main (CM) 3 front/2 rear, LFE on,, 448 kbit/s reserved Dolby Surround mode Afterwards, I have run the following: gst-launch-0.10 filesrc location=mkv.0 ! queue ! mux.video_0 avimux name=mux ! queue ! filesink location=house.avi filesrc location=mkv.1 ! queue ! mux.audio_0 But the end result is a unplayable file. This is the output from mplayer: AVI file format detected. [aviheader] Video stream found, -vid 0 [aviheader] Audio stream found, -aid 1 Detected NON-INTERLEAVED AVI file format. VIDEO: [] 0x0 0bpp nan fps -17179870.0 kbps (-2097152.0 kbyte/s) FPS not specified in the header or invalid, use the -fps option. ========================================================================== Forced audio codec: mad Opening audio decoder: [pcm] Uncompressed PCM audio decoder Unknown/missing audio format -> no sound ADecoder init failed :( Cannot find codec for audio format 0x0. Read DOCS/HTML/en/codecs.html!

Hi,
You probably need the elementary stream parser elements after the filesrc. The muxer is unware of the data format that is getting.

Most likely the problem below is that avimux refuses the caps because they do not provide width and height, which are not parsed from the stream and put in the caps by h264parse. (see also http://bugzilla.gnome.org/show_bug.cgi?id=530513) Besides this, codec_data is not provided either, which may not prevent muxing but likely causes problems further down when trying to play. Having no codec_data on the input caps also makes h264parse believe the input is bytestream format, which it may not be as it extracted from a framed/packetised source. Bottom line; this approach is (presently) not quite recommended. Mark.

Re: muxing streams

The whole story is that I tried with the original file like this:
$ gst-launch-0.10 filesrc location=file.mkv ! matroskademux name=d d.video_00 ! queue ! m.video_00 d.audio_00 ! m.audio_00 avimux name=m ! filesink location=file.avi but it gets stuck with this output: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... So I tried demuxing it first using: $ gst-launch-0.10 filesrc location=file.mkv ! matroskademux name=d d.video_00 ! queue ! filesink location=mkv.0 d.audio_00 ! filesink location=mkv.1 which also gets stuck without putting a queue element between the audio output and the filesink. But then I checked that the video stream extracted seemed to be corrupted because it wasn't recognised by the file command and it is different from the output produced by mkvextract whose output is recognised by file. Should I file bug reports for theses issues?
