Overview

These patches add VA-API support to Gnash.

Note: this work is now integrated into the upstream 'hwaccel' branch. Build and run-time instructions changed. In particular, running with VA-API support requires the --hwaccel vaapi options or proper setup in ~/.gnashrc.

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
```
Then, you can configure gnash-vaapi with the --enable-vaapi --enable-renderer=agg --enable-media=ffmpeg options. That is, VA-API support requires use of the AGG renderer and the FFmpeg media handler. Note that AMD platforms will currently require the OpenGL ("ogl") renderer.

Running VA-API enabled Gnash

VA-API is used by default for all H.264 videos. HW requirements:

AMD GPUs with UVD2 and 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

Caveats

Best performance is obtained with the OGL renderer but it is not fully correct yet.
There is no means to force SW video decoding but with the GNASH_VAAPI environment variable set to "no" (without double quotes).
