[gst-devel] muxing streams

[Henrique Ferreiro García]

I changed the pipeline to:

gst-launch-0.10 filesrc location=mkv.0 ! h264parse ! queue ! mux.video_0
avimux name=mux ! filesink location=house.avi filesrc location=mkv.1 !
mux.audio_0 --gst-debug=2

and this was the result:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
