We support 5.1 for a while now.
Resend as the last one didn't have the CCs.
I know (well think) vdpau doesn't really mention 5.2 anywhere, but for
ffmpeg I've been making this change for some time to say 5.2.
Tonga can easily do 5.2, players don't seem to look at this field, but
ffmpeg cli now does and will refuse to use uvd for 5.2 vids.
5.2 requires the hardware to handle more than twice as much macroblocks
per second than 5.1. So the decoder needs to handle 4k at 66fps.
I'm not sure about the absolute numbers, but I think that could be to
much even for a Tonga.
In the past ffmpeg cli also didn't look at this, but they merged
something in from libav which changed things.
I have a trac open, but the dev who replied said fix the driver - he
didn't reply further when I said I didn't think vdpau went as high as
5.2 ...
VDPAU actually doesn't have an enumeration for the level, so you can
even return something like 9.9 without a problem.
Regards,
Christian.
