Hardware Accelerated Video Decoding on HoloLens
The HoloLens has this SoC built-in: Intel Atom x5-Z8100 1.04 GHz
There's not much info available about the supported video codecs that run on the chip. The only I could find was about the 8300 which mentions numerous supported codecs for decoding: https://en.wikichip.org/wiki/intel/atom_x5/x5-z8300
It is clear that H264 is hardware accelerated on the 8100 the HoloLens uses, but I was wondering if H265, VP8 and VP9 are also hardware accelerated for decoding?
Is tis exposed via Media Foundation?

Hi René,
Have you learned anything about HoloLens hardware codecs? This is one of the top results on a google search about the topic.
Cheers,
Adam
Hey Adam!
The HoloLens supports H264 hardware accelerated decoding just fine but not VP8 nor H265. It seems it can decode 2 streams in parallel. A 3rd H264 stream will make it fall back to software decoding.
We are using Windows Media Foundation in order to access the HW H264 decoder for our WebRTC streams.
Hope that helps.

Thanks, that makes sense. Any info on VP9?
Hi René,
according to https://en.wikichip.org/wiki/intel/atom_x5/x5-z8300, the hardware does support H265 decoding.
"Video decode hardware acceleration including support for H.263, MPEG4, H.264, H.265 (HEVC), VP8, VP9, MVC, MPEG2, VC1, JPEG."
could you please elaborate why no support for H265 on HoloLens?
Thanks in advance for your feedback.
