The first problem is that there is no compatible version of 'xvba-video'
included with Ubuntu 10.10, and the 'official' version from splitted-desktop is
incompatible with Ubuntu's version of 'libva1'. So you have to overwrite the
built-in version with the matching file from splitted-desktop.
__________
The initial goal here is to get the 'vainfo' diag to report a list of
supported codecs, e.g.
> vainfo
libva: libva version 0.31.1-sds1
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/va/drivers/fglrx_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.31
vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.7.7
vainfo: Supported profile and entrypoints
VAProfileH264High : VAEntrypointVLD
VAProfileVC1Advanced : VAEntrypointVLD
NOTE - in this example there are only 2 codecs listed; there should be more?!
____________
Unfortunately, even if you get vainfo to work 'properly' you'll still
likely have problems getting apps like VLC or XBMC to work properly.
Even when run in full-debug ("--verbose 2") VLC only reports:
libva: va_getDriverName() returns -1
avcodec decoder warning: Failed to open VA API
So, is there a symbolic link missing somewhere? I've followed about a dozen
How-To's and everything seems to be setup correctly... it just doesn't work
like they say!
_____________
One clue: different versions of the xvba-video driver result in
different supported codecs be listed in vainfo. So maybe the
(secondary) problems are all caused by instability in it's code?
