I get this kinda error with this:

[00000368] stream_out_transcode generic debug: number of audio channels for mixing changed, trying to reopen the encoder for mixing 2 to 2 channels
[00000417] main encoder debug: looking for encoder module: 6 candidates
[00000417] avcodec encoder debug: libavcodec already initialized
[00000417] avcodec encoder warning: Only mono supported
 (libamr_nb at 0x11329d0)
[00000417] avcodec encoder error: cannot open encoder
[00000368] stream_out_transcode generic error: cannot find audio encoder (module:any fourcc:samr)

I think it ain't related to this particular commit (atleast didn't spot
any obviuous reason), instead transcode doesn't seem to set channelcount
to 1 in current git master.
