This command:
$ gst-launch --gst-debug=1 audiotestsrc ! ffenc_g726 bitrate=16000 ! ffdec_g726
! alsasink

should produce sound in the speakers but it only produces such an output on the
screen:

I tried setting bit_rate, channels, codec_id and sample_rate in code. I got rid
of errors but I get only silence in my speakers. The weird thing is that
frame_size is always 0.
