muxing streams

[Henrique Ferreiro García-2]

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!
Audio: no sound
Video: no video

Am I doing something wrong?

You already asked this question didn't you? There's no way the muxer
can know what is the input coming from filesrc.

It seems mkv.0 and .1 came from a clip, why not write the whole
pipeline for gst-launch?
