It's not supported at the moment. But if matroska can support it, you
could extend matroskamux too.

This works indeed, I keep forgetting about it. Note it's GStreamer
specific. For the reference:

Record,
gst-launch-1.0 audiotestsrc ! avenc_g726 bitrate=1600 ! gdppay !
filesink location=test.gdp

Playback:
gst-launch-1.0 filesrc location=test.gdp ! gdpdepay ! avdec_g726 !
pulsesink

cheers,
