I don't see much point in that anyway since, AFAIK, those players don't support offloading decoding to DSP anyway. If the support is added, then it should be fairly trivial to use some other than ALSA interface for the purpose. For good video synchronization there should be timing feedback from the decoder output (D/A feed stage). However, these are fairly simple cases compared to environmental 3D audio... (environment parameters, passive scene objects, active scene objects with streams, etc) Some of these could be implemented through ALSA control interface and virtual channels, but there are still various interaction issues left and those passive objects are a bit problematic to represent this way. > If I will use sample format "special" will the alsa know not to try and > do manipulation over it? (resampling, volume, etc...) One of the common cases would probably be to feed AC-3 or dts audio to S/PDIF. These should work? _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
