[Mesa-dev] [Libva] vaPutSurface never returns

[Emil Velikov]

Was about to mention the same thing as Christian :-)

Vasilis, is there any reason why you're using vdpau + the vdpau to
vaapi adapter, as opposed to the gallium vaapi target directly ?

Mesa 11.0.x has the said target (toggle with --enable-va at configure
time), although there has been quite a few fixes from Christian,
Julien and others since then. As an alternative I'd suggest mesa
11.1.x series (or mesa 11.2.0-rc1 coming out later on today).
