[LINUX] Add VAAPI (VA API) Video Acceleration API support?

my1997golf · 2010-05-20 23:41

I've been encountering the same issue (no vaapi option, auto-detect gives blank screen) over the past few days with an ATI Radeon HD4550. I have tested that vaapi works using mplayer independently. I thought it was something I had done wrong in the setup and tried reinstalling ubuntu / recompiling xbmc. Hope this gets fixed soon.

Looks to be fixed in the daily SVN. Working for my combination of a ATI Radeon HD4550 with a single core Intel Celeron CPU (plays 1080p successfully)

A lot of you seem to have ATI hardware. Did you encounter any problems? Last Time i checked, i had a very jumpy experience, the Frames seemed out of order sometimes.
I will try it tomorrow evening.

BTW the shader issue seems to be a different story.

On ATI hardware I would not say that it is jumpy but I did notice some tearing on occasion. Not sure if that is a setting somewhere that I have wrong

vaapi not showing again on svn30388.
It compiled yesterday and showed but I had playback issues. So I tried to compile again today and now vaapi does not show up in system - video -playback.

anyone else seeing this?

I tried it with r30380. Compile was ok for me, but with an nvidia backend i have a lot of problems:

- Playback is "jumpy". Frames get still for a few refreshes, sometimes go back and forth on frames.

- Sometimes i get low framerates.

- i lost all interlacing options.

Just checked the trunk and now VAAPI is there.

Unfortunately the playback is somehow broken.
I've a 720p display but the source is 1080p.
What I see looks somehow like this:

Code:

--------------------

|     X     |       |

|------------       |

|                   |

--------------------

The upper left rectangle (the one with the cross) shows some part of the film but the lower and right area is only showing graphics errors.
It seems that it's somehow some 1080p/720p scaling issue!?
The X-rectangle seems to have the 720p size compared to the rest of the screen.
The part of the film which is shown within the X-part is only the left upper part of the film itself - so it's not scaled down to fit into the X-part.

Any idea? I'll check it with 720p sources later.

There are no interlace handling support with vaapi.

Hi elupus. Do you guys have any plans to support de-interlace with vaapi?

If the api adds support for it yes, but that is not the case currently.
