So steam has added support for intel hw decoding.
Does anyone knows how to activate this on Arch linux?
Ive installed libva-intel-driver and libva, but it keeps using software decoding.
Could it be because im running a 64 bit version? and steam runs on 32 bits?
This is my vainfo output.
libva info: VA-API version 0.35.1
libva info: va_getDriverName() returns 0

I tried installing lib32-libva and lib32-libva-intel-driver from AUR, but they are out of date, steam requires libva-driver to be at least 1.3.2.

Solved it. I had to install the 32 bit versions but since the ones in the AUR are out of date i had to manually modify the PKGBUILD to point to the latest version.
After that it was just a matter of symlinking to where steam wants to find the library
sudo ln -s /usr/lib32/dri/i965_drv_video.so /usr/lib/i386-linux-gnu/dri/i965_drv_video.soOffline
I was just about to post the same exact thing. Switching to vaapi decoding didn't seem to resolve any of my sound related issues with streaming though. <sigh>

See: Here
Apparently Intel graphics do not support the "GL_NV_vdpau_interop extension" that is required for hardware decoding on the client. I have done every single thing possible and I am still getting software decoding with an Ironlake Intel HD Graphics (first generation Core i5 650).
Enable -> Steam -> Settings -> In Home Streaming -> Advanced Client Options -> Display Performance Information.
When you launch a stream, press the option indicated in the bottom left of the screen to get detailed information and see if you really are being hardware accelerated or if it is just a placebo?

Adding some more information:
I updated the PKGBUILDs of both lib32-libva and lib32-libva-intel-driver and built and installed them successfully. I followed the: VDPAU page and configured it properly, including setting the environment variable that tells the system to use the Intel backend. I tried your symbolic link even though the same link is present in Steam's runtime within your ~/.local/Steam/.. folder. Steam streaming still uses software decoding. VDPAU is configured correctly on my system as other programs which use it work correctly with the above configuration I did. "vainfo" and "vdpauinfo" indicate that it is correctly configured.
Like I said, I am using a first-generation Core i5 650. That is "Intel HD Graphics" with no other suffix, otherwise known as "Ironlake" graphics. I am using the official xf86-video-intel in the main repos and not the devel version in AUR. The version of my Intel driver is "2.99.914-4".
Edit:

I think you are a bit confused about VA-API and VDPAU they are 2 different things, afaik intel driver doesnt implement VDPAU. As the title of the post says ive got VA-API hw decoding working on steam, the debug overlay says so too, not VDPAU.

Thank you for the reply. This thread no longer applies for myself though, I popped in an Nvidia card in my machine so now I'm on a different path. Thanks again though!
