[MPlayer-users] encoding with flacenc fails...

flacenc in libavcodec fails to work.
surely i made some corrections to see what was the problem...
log shows that flacenc doesn't seem to work properly. because it just gives
14 byte when it imported 60kb stream.
and encoder->decode_buffer_size in libmpcodecs has fewer size than flacenc
needs.
example.... 18kb < 39kb
so it will output 'output buffer too small' and it fails.
so when i set up workaround so that encoder->decode_buffer_size > 39kb .
you can see flacenc continues to give 14 byte.....
in 6 sec, it suddenly gives normal bitstream (6kb 9kb etc.....)
but video packs are full so audio codec doesn't seem to work anymore.
