Overview

These patches add VA-API support to Gnash. Actually, this is now upstream. So, no more patches at this time.

Hardware requirements

AMD GPUs with xvba-video >= 0.6.5 VA driver (AGG or OGL renderer)
NVIDIA GPUs with vdpau-video >= 0.6.3 VA driver (AGG or OGL renderer)
Intel GMA500 with the psb VA driver (AGG renderer). IEGD is not supported
All HW with a VA driver supporting the VA/GLX extensions or vaPutSurface(Pixmap,...). This may include the Intel Moorestown platform and future G45 VA driver

Quick build notes

Gnash-vaapi requires libVA API >= 0.31.0-sds3, i.e. VA-API with Splitted-Desktop Systems API extensions revision 3, as implemented in libva >= 0.31.0-1+sds3 packages that can be found here: http://www.splitted-desktop.com/~gbeauchesne/libva/. You will generally want to download the latest libva packages and patches anyway. NOTE: the current Gnash/VAAPI patchset was tested with libva 0.31.0-1+sds9.
Gnash-vaapi also requires the latest VA-API-enabled FFmpeg, with H.264 decoding acceleration. This matches upstream FFmpeg SVN rev 21285 or newer.
Make sure you also have bzr (Bazaar) and all necessary Gnash build dependencies installed on your system.
On a Debian system, the following commands will help you install the required files:
```
# apt-get build-dep gnash
```

Checkout current Gnash trunk (rev >= 12042):

$ bzr branch http://bzr.savannah.gnu.org/r/gnash/trunk

Configure and build Gnash with VA-API support:

$ ./autogen.sh
$ mkdir objs.vaapi
$ cd objs.vaapi
$ ../configure --with-hwaccel=vaapi --enable-media=ffmpeg
$ make -j4

Running VA-API enabled Gnash

Enable VA-API on demand:

$ gnash --hwaccel vaapi some.swf
$ gnash --hwaccel vaapi -R agg some.swf (force AGG renderer)
$ gnash --hwaccel vaapi -R ogl some.swf (force OGL renderer)

Enable VA-API by default, if supported on your system, through a setting to your ~/.gnashrc file
```
set hwaccel vaapi
```

Caveats

Best performance is obtained with the OGL renderer but it is not fully correct yet.
