Google Still Doesn't Trust Linux GPU Drivers Enough To Enable Chrome Video Acceleration
There was a discussion once again about shipping Chrome with Linux GPU video acceleration enabled. But once again Chrome developers feel that the cons and increased maintenance burden of having to deal with Linux GPU video acceleration problems outweigh the benefits of a better Linux video playback experience and possible power-savings. Of course, that's unless talking about Chrome OS where they do have GPU video acceleration within their Linux-based OS.
Besides the maintenance burden itself, other reasons attributed to not supporting it are that AMD/Intel drivers rely upon VA-API where as NVIDIA's preferred video acceleration route is now with their proprietary NVDEC interface. As well, "the constant stream of incoming issue due to new hardware, driver, or distribution release. Many of these issues are not even directly attributable to this or that acceleration feature (e.g. causing random memory corruption or GPU hangs), so even investigating to narrow down a blacklist entry is significant non-trivial work. As we do not have the resources to commit to dealing with this continued incoming stream of issues, and we don't want to compromise the first goal (stable and secure browser), our choice is not to enable these acceleration features on Linux."
