[gst-devel] g726 unsupported?

[Tomasz Grobelny]

How do I encode voice with G.726? The most obvious thing doesn't work as 
expected:

$ LANG=C gst-launch --gst-debug=1 audiotestsrc ! ffenc_g726
Setting pipeline to PAUSED ...
Pipeline is PREROLLED ...
0:00:00.092058914  6580 0x816ef58 ERROR               ffmpeg :0:: G726:

ERROR: from element /pipeline0/audiotestsrc0: Internal data flow error.
Additional debug info:

ERROR: pipeline doesn't want to preroll.

Why is "G726: unsupported audio format"? Thanks in advance,
