Hi all!
This patchset adds support for passing through IEC 61937 encapsulated compressed audio at high bitrates (i.e. those over 6.144Mbps). At least TrueHD and DTS-HD are such formats.
I've tested this using an NVIDIA hdmi codec and the following ffmpeg patch which adds support for TrueHD in its IEC 61937 muxer: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2010-August/094317.html
One needs to set the AES0 & 0x02 (non-audio) bit during playback so that the data is not transmitted as normal 8 channel PCM audio.
Thanks, I applied both patches.
There are some magic numbers there like 0x8000, and I'm going to define them...
Yeah, I guess all the Stream Format bits should be defined to get rid of all the existing magic numbers in snd_hda_calc_stream_format() as well.
Exactly.
