That is definitely exciting.  Will keep an eye on this for sure

mattkhan:
It basically works now as far as I can see so you just need a card to test it out

mattkhan:
for audio, I found https://learn.microsoft.com/en-us/windows/win32/coreaudio/representing-formats-for-iec-61937-transmissions which looks like it corresponds to the info in 6.6.1 of https://ia903006.us.archive.org/11/items/CEA-861-E/CEA-861-E.pdf (HDMI audioframe) so I guess I should be able to try to send such encoded content from my filter in the right format, whether it works or not is probably something that's going to take a bit of time to test out

mattkhan:
Looks like https://ffmpeg.org/doxygen/trunk/spdifdec_8c_source.html#l00189 is what is needed to determine the contents of the bitstream

mattkhan:
Managed to successfully receive ac3, now to work out how to push that through mc
