Hi guys,

I just found out that Adobe disabled linux hardware acceleration in flash-player 11 because of security concerns ... ( Adobe Forums: FP11 Linux Hardware Acceleration? ).
Well, I use flash almost only to watch Youtube videos and I don't care at all about Adobe's security concerns, so here is a quick way to have accelerated flash playback:

1. Install flash-player-10.3.183 from OBS

2. Edit/create /etc/adobe/mms.cfg and add the following lines:
Code:
EnableLinuxHWVideoDecode = 1
OverrideGPUValidation = 1
Note: the last option is a bit dangerous, forces the HW video acceleration even if you card does not support it. Right now only vdpau acceleration is supported by flash. which requires binary NVidia drivers. Use this last option with care, if you are not sure, don't put it in your mms.cfg file.
