*	vaapi: make struct va_surface private	wm4	2014-03-17	1	-16/+6
\| \| \| \| \| \|	It's not really needed to be public. Other code can just use mp_image. The only disadvantage is that the other code needs to call an accessor to get the VASurfaceID.
*	vaapi: replace image pool implementation with mp_image_pool	wm4	2014-03-17	1	-13/+6
\| \| \| \| \| \| \| \| \| \| \| \|	Although I at first thought it would be better to have a separate implementation for hwaccels because the difference to software images are too large, it turns out you can actually save some code with it. Note that the old implementation had a small memory management bug. This got painted over in commit 269c1e1, but is hereby solved properly. Also note that I couldn't test vf_vavpp.c (due to lack of hardware), and I hope I didn't accidentally break it.
*	vaapi: mp_msg conversions	wm4	2013-12-21	1	-8/+11
\| \| \| \| \| \|	This ended up a little bit messy. In order to get a mp_log everywhere, mostly make use of the fact that va_surface already references global state anyway.
*	vaapi: check image format in va_surface_upload()	wm4	2013-09-27	1	-1/+1
\| \| \| \|	Just for robustness. Also print a warning in vo_vaapi if this happens.
*	vaapi: potentially make reading surfaces back to system RAM faster	wm4	2013-09-27	1	-1/+5
\| \| \| \| \| \| \| \|	Don't allocate a VAImage and a mp_image every time. VAImage are cached in the surfaces themselves, and for mp_image an explicit pool is created. The retry loop runs only once for each surface now. This also makes use of vaDeriveImage() if possible.
*	vaapi: add vf_vavpp and use it for deinterlacing	xylosper	2013-09-25	1	-14/+63
\| \| \| \| \| \| \| \|	Merged from pull request #246 by xylosper. Minor cosmetic changes, some adjustments (compatibility with older libva versions), and manpage additions by wm4. Signed-off-by: wm4 <wm4@nowhere>
*	vaapi: fix typo	wm4	2013-08-14	1	-2/+2

*	video: add vaapi decode and output support	wm4	2013-08-12	1	-0/+73
	This is based on the MPlayer VA API patches. To be exact it's based on a very stripped down version of commit f1ad459a263f8537f6c from git://gitorious.org/vaapi/mplayer.git. This doesn't contain useless things like benchmarking hacks and the demo code for GLX interop. Also, unlike in the original patch, decoding and video output are split into separate source files (the separation between decoding and display also makes pixel format hacks unnecessary). On the other hand, some features not present in the original patch were added, like screenshot support. VA API is rather bad for actual video output. Dealing with older libva versions or the completely broken vdpau backend doesn't help. OSD is low quality and should be rather slow. In some cases, only either OSD or subtitles can be shown at the same time (because OSD is drawn first, OSD is prefered). Also, libva can't decide whether it accepts straight or premultiplied alpha for OSD sub-pictures: the vdpau backend seems to assume premultiplied, while a native vaapi driver uses straight. So I picked straight alpha. It doesn't matter much, because the blending code for straight alpha I added to img_convert.c is probably buggy, and ASS subtitles might be blended incorrectly. Really good video output with VA API would probably use OpenGL and the GL interop features, but at this point you might just use vo_opengl. (Patches for making HW decoding with vo_opengl have a chance of being accepted.) Despite these issues, decoding seems to work ok. I still got tearing on the Intel system I tested (Intel(R) Core(TM) i3-2350M). It was also tested with the vdpau vaapi wrapper on a nvidia system; however this was rather broken. (Fortunately, there is no reason to use mpv's VAAPI support over native VDPAU.)
