[FFmpeg-user] libopus encoder problem.

[bat guano]

Hi
libopus encoder has been added to FFmpeg git, but it doesn't seem to be working properly.

$ ffmpeg -i foo.wav -c:a libopus -b:a 64k foo.opus

Gives error "Trying to remove 480 samples, but que empty"

Is this an FFmpeg bug, or is the libopus encoder still "work in progress"?
