Initializing H264 HW acceleration via DXVA fails at
MFT_MESSAGE_SET_D3D_MANAGER failed with code C00D6D60.

According to DXVA checker my graphics card supports H264 decoding and also other applications(e.g. mpv ) can use the HW support via DXVA. I already installed the latest Nvidia drivers.

What version of Firefox are you using?

Is this reproducible in Firefox nightly?

Does setting media.windows-media-foundation.allow-d3d11-dxva=false in nightly make a difference?

I was using Firefox  Nightly from last week.

I will update to the current nightly and check if 


makes a difference as suggested in #1.

Using Firefox Nightly 2016-05-20 and setting media.windows-media-foundation.allow-d3d11-dxva=false doesn't help. I still get the same error message: 
Hardware H264 Decoding: No; MFT_MESSAGE_SET_D3D_MANAGER failed with code C00D6D60

      // TODO: Test if I need this anywhere... Maybe on Vista?
      //hr = attr->SetUINT32(CODECAPI_AVDecVideoAcceleration_H264, TRUE);
      //NS_ENSURE_TRUE(SUCCEEDED(hr), hr);


Is the call perhaps needed on Vista?

I don't know. I saw this in the Chromium source code, but on all the Vista machines I tested on, I could not see any behaviour change.

same problem on every version of FF under OS X. Not only is about:support unreliable as it only correctly shows HW-Acceleration supported in FF Nightly and Dev, it doesn't even matter since it isn't used anyway. Even though I disabled that useless Cisco Plugin and installed h264ify to force h264 on youtube and checked it via the info for geeks dialog in the videos it still isn't using hardware decoding. 

The consumed CPU usage is >35% on a 2012 Core-i7 Mac with OSX 10.10.5 and Nvdidia GT550M
Compared to Chrome, Iron or Safari this is hopelessly bad, since they use 5% at most.

in Firefox 48.0b3, 48.0b4 
not work hardware decoding H264 on Nvidia 750ti
so and on video from youtube in fullscreen load cpu about ~30-40% 
youtube used codec mp4 avc1

in Firefox 47.0 hardware decoding h264 work fine! and load CPU was 5-8%

i'm so check this with new (clear) profile.

Firefox 48.0b4 x64,

I am seeing this on 48.0 final. Windows 7 64bit. 

Using AMD Radeon HD 6670, latest available drivers 15.301.1901.0.  Hardware accelerated h264 decode worked well up to 47.0.1. Never any instability after 1000s of hours of video. Now, in 48 (I believe from b3 up to final it seems hardware h264 decoding is blacklisted for no apparent reason (about:support shows no support for h264 hardware decode in 48.0.)
