Example of setting audio-stream-combiner to an 'adder'
Run like:
python3 playbin-multi.py
https://dl.dropboxusercontent.com/u/61100892/test.mkv
The test.mkv file was generated with two videotestsrc and two audiotestsrc. I
don't remember the exact command, but this will give you something similar:
gst-git gst-launch-1.0 videotestsrc num-buffers=100 ! theoraenc !
matroskamux name=mux ! filesink location=example.mkv videotestsrc
num-buffers=100 pattern=checkers-8 ! theoraenc ! mux. audiotestsrc
num-buffers=300 ! vorbisenc ! mux. audiotestsrc wave=white-noise
num-buffers=300 ! vorbisenc ! mux.
