I suppose you would then change the actual device name to e.g. "surround51" if your input data has 6 channels, and you'd append the "CARD=PCH,DEV=0" parameters according to the selected device by the user. But I don't know if this is ideal. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
