disable-accelerated-video-decode not available on Linux

Project Member Reported by schartain@google.com, Sep 22 2016

Issue description

We are noticing some video stuttering issues that we think may be related to this accelerated video decoding. It would be great to be able to disable it for testing. We need other GPU acceleration for other aspects of our web content. It would be nice to toggle accelerated video decoding off individually from other features.

Why isn't this flag available in Linux? Can it be added in a future chrome release?

chrome://flags/#disable-accelerated-video-decode is not available in Linux
because VDA is disabled in Linux by default :-) -- see, e.g. the 
discussion in https://crbug.com/590209 for more context.
I can't view the discussion link. The purpose of this FR was to isolate the accelerated -video-decoding feature from the rest of the GPU features. In our particular use-case, we have a Linux server running Nvidia graphics cards. We have a Chrome app which uses WebGL, and thus requires some GPU features. However, the app also contains embedded video, and when we enable the GPU, there is a noticeable stutter in the video playback. This stutter is due to the fact that the video decode feature of the GPU does not work on Linux, thus it falls back to CPU decode, which works. Using the flag in question would be a means of forcing CPU decode in this situation, without losing other GPU features.
