Probably an issue with your version of the ffmpeg libs. Try a newer version if you can. Or try removing the '#if' and '#endif' lines in resample.c and recompile. (Check the values of the LIBAVUTIL_VERSION_* macros in your libavutil/version.h - there doesn't seem to be a consistent version test to check for the existence of av_frame_get_channels())

Cheers
