There is no slndec, but it's the sln demuxer, so it seemed better than to write pcmdec. I can change it if you want. And yes, I was going to deprecate the channels option, but in a separate patch(set). > > - Andreas > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".

The demuxer doesn't do anything with the value. The demuxer calls pcm_read_header() as init, which uses it.
