[Mesa-dev] Hardware assisted (VDPAU) decoding of MPEG-2 causes GPU lockup on Radeon HD6320

[Christian König]

Hi Will,

well that's the very first APU generation and unfortunately nobody is 
working on that old hardware any more.

MPEG2 is known to not be fully supported by that chipset in general. So 
the best approach is probably to not use hardware acceleration for MPEG2 
clips in general.

Regards,
Christian.
