I'd recommend to resample using audio filters. It can convert between number of channels, sample format, sample rate. See doc/examples/filtering_audio.c Filterchain string "aresample" should do that. -- Andrey Utkin _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
