does the nvidia soulution lossless FFV1 to?? and ogg:theora1.6? FFmpeg MPEG-4 ?

FFMpeg Mpeg 4 yes it does. As far as FFV1/ogg support goes it can be done using a openCL solution if needed and the motivation/demand is warranted.

i think dirac in cuda is droped !

Still works fine.

Again supply vs demand. Nothing you have mentioned specifically eliminates nvidia solutions.

Did you really watch XVID/DIVX over vdpau once? I would not consider that working...

h264 (DivX 6), mpeg 2 and wmv videos are near 0 cpu overhead here with my 9800gt. Maybe your hardware is an older generation like mine coz as far as I know some formats are not accelerated with them. I can't confirm dirac because I don't have any sample with dirac encoding (I think). Can anyone show me a place to download one?

And Q: dream on.

Not with my GT220 with mplayer svn, could you test that please?

[barbarbaron]

test what? mplayer or GT220? Sorry I don't use mplayer XBMC forever.

[Kano]

who can confirm that it is fully hw accellerated with xbmc? you can use software codecs too with vdpau output with mplayer.

[barbarbaron]

I do it with quitting xbmc and within 60 seconds looking at system monitor cpu history. Any better method to test it?

[Kano]

i only know that

mplayer -vo vdpau -vc ffodivxvdpau movie

uses full hw accelleration and that really looks ugly with my testfiles.

[Kano]

Well on my systems generic divx/xvid files need 3-5% cpu usage even without accelleration, but some may have got slower systems like atom. There something like ion2 could have got vp4, but currently it does not work correctly.

[barbarbaron]

Did you try with high resolution wmv files such as this one?

Nice find, does not work with vaapi/xvba with a 3450 (did not test 4550). Maybe because it is not pure vc1, when you test with nvidia (pure svn) you see:

Selected video codec: [ffwmv3vdpau] vfm: ffmpeg (FFmpeg WMV3/WMV9 (VDPAU))

files working with vaapi/xvba use:

Selected video codec: [ffvc1vdpau] vfm: ffmpeg (FFmpeg WVC1 (VDPAU))

It works with vaapi/nvidia btw.
