Hi, Intel has recently open sourced otion compensation code (XvMC) for their i915/i945 integrated graphics chips. See: http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blob;hb=xvmc-i915;f=src/xvmc/I915XvMC.c XvMC API was intended for MPEG{2,4} class of codecs - so it can not be used for Theora as-is. However, could at least some parts of it s...

...e for, they just care about a functional and efficient 2D driver, and having video acceleration would complement that nicely and entice them to switch from the Nvidia binary driver and the old nv driver long before the people who want the 3D features. I've read through jb17bsome's notes on XvMC and I think all the work he's done so far is a great head's up on what's involved. I've also read through the VAAPI page and I think that would also be a great feature to try and support given all the non-MPEG2 video content out there, it would probably entice even more people to us...

Meh. Like I said, don't worry about it. On closer inspection, it's most likely the nv31_mpeg_tile_prog function. Althou...

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for

...tv is showing the first and second fields. There's no parameter for that in Xv to know which field a particular XvPutImage corresponds to as far as I know. In fact I'm not even sure if Xv knows anything about interlaced video, seems we just get full frames from the player and display them. XvMC seems a little better, XvMCPutSurface has first and second field params, so you would then sync only after the 2nd field is drawn I take it?

...Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Tested on NV42. Ben, I'm going to guess that you hate this patch, since it gets rid of the beautiful nv_call stuff. However I wasn't sure how to make it work without doing that. Also worth noting that playing back two files via xvmc at the same time corrupts the playback. Not sure what's going on there. I don't think I ever tested it on NV44/NV96 either, but I will next time I get a chance. Also note that this *still* doesn't work on a NV34. (Even with some additional patches that fix up more nv3x vs nv4x differen...
