How good is Linux support for these? I was under the impression that
XvMC doesn't work with ATI at all, and is broken in many versions of
NVidia's Linux drivers. And that the latter don't support deinterlacing
even though the hardware has been capable for quite a while now (since
6600 I heard).
A list of NVidia hardware capabilities is here:
As for current XvMC support, only IDCT and Motion Compensation with
MPEG2 (and possibly MPEG1) are available in hardware - no hw deinterlacing.
Full support may happen eventually, judging by a comment here from
http://macslow.thepimp.net/ (see bottom of "UDS 2006 recap, Google,
nVIDIA etc." article.)
"Furthermore I hinted them towards us OpenSource folks wanting to see
nVIDIA’s PureVideo HD chip-features exposed in the Linux-drivers too.
They have plans for that, but not in the immediate future."
