Issue : h.264 hardware decode does not seem to be working.
Driver : Nvidia 340.108 recommended driver from the tools.
CPU : T9500 2.6 ghz
Memory 6 Gb.
I would like to use the hardware decoding built into the video card. Everything I have read states that this card supports it.
However when I run steam remote play I see its on dedicated software decode.
When I run firefox I see software decode on youtube videos.
Any application I have seems to be running in software mode. I have tried installing libva packages but no luck.
Does anyone have any hints on how to get this to kick in properly?

updated info :
So I can set VLC manually to us vdpau mode. That will drop cpu usage from 20-30% down to 2%. So I know that hardware decode can and does work.
However for some reason it will not "auto select" this mode.
I have also found running vdpau info it show support for hardware decoding of h264 "Main" and "High" profiles but NOT "Baseline" which seems odd.
I am still looking for answers.
