So with providing -a:c XY I can do all the formats (or pcm codecs so to speak) in one muxer where I had seperate muxers for before. So v2 works like the examples you gave for alsa. Might even work for compressed codecs depending on what OSX accepts. However you say we cannot avoid the auto scaler? I'm not sure what you mean we cannot do... And do you think v2 is still object for improvements regarding this? > The solution to have format negotiation would be to make sure all output > devices have a matching lavfi sink.

This let's me think you're referring to some more general design shortcomings. Not sure if you relate that to the patch or something in general we should do prior to do the audiotoolbox output device.

While not yet upstream, my version of the decklink output module provides a single avdevice that supports multiple formats, including AC-3 for passthrough. https://github.com/LTNGlobal-opensource/FFmpeg-ltn/blob/lted1/libavdevice/decklink_enc.cpp Devin -- Devin Heitmueller, Senior Software Engineer LTN Global Communications o: +1 (301) 363-1001 w: https://ltnglobal.com e: devin.heitmuel...@ltnglobal.com ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

We cannot, not with your original version, not with how alsa_enc does and the new version. Because they are not sample formats, they are codecs, and converting from a codec to another is more complex than just a resampler. And even if in these particular cases they are trivial codecs, they could easily not be: ALSA supports S/PDIF, so it could be AC3 or something. The solution to have format negotiation would be to make sure all output devices have a matching lavfi sink. Unfortunately, for now, I am not sure lavfi's scheduling work with non-buffer sinks.
