User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:49.0) Gecko/20100101 Firefox/49.0 Build ID: 20161019084923 Steps to reproduce: Enable Hardware Acceleration. Actual results: On Nightly if you have Hardware Acceleration enabled, YouTube videos (HTML5 player) won't play, it gives the TV static noise video with error message "An error occurred. Please try again later." But if you disable acceleration, then it works. But again, if you disable acceleration, the font rendering becomes messed up, the browser doesn't render correctly many major fonts like Arial or Verdana with acceleration off. So I need Hardware Acceleration setting ON. I have no addons installed. Expected results: Should play YouTube videos on HTML5 player with no problems. Not to mention it works fine on normal Firefox version (latest 50.0 as of now, but Nightly is 53)

how do you enable hardware acceleration ? Or how do you disable it for that matter?

Can you please use the mozregression tool to find out which version introduced the regression? https://mozilla.github.io/mozregression/ it's very simple to use.. Enter the version that works, and the one that doesn't.. post the result here.. it shouldn't take long

(In reply to Jean-Yves Avenard [:jya] from comment #1) > how do you enable hardware acceleration ? Or how do you disable it for that > matter? you go to settings Advanced -> General -> tick Use hardware acceleration when available

Looks like the same issue you mentioned earlier today on #developer

(In reply to Jean-Yves Avenard [:jya] from comment #5) > Looks like the same issue you mentioned earlier today on #developer Must've been someone else with same problems, but I did mention that yesterday on #firefox and #nightly (nobody responded though) i never was on #developer

I've had at least three Nightly users report this same issue in #firefox. All of them reported that setting media.gpu-process-decoder to false and restarting the browser fixed the problem. So if that got enabled recently that looks like your culprit. I spoke with someone on Windows with Nightly for whom youtube did work fine, so it does not seem to be for everyone. Maybe just some GPUs.

[Tracking Requested - why for this release]: Can't play videos on Youtube. For some reason, I can only reproduce this with my regular profile. If I create a new one, it doesn't reproduce even with the same build. That said, I was able to use my dirty profile with mozregression to confirm that this does indeed bisect to bug 1315141 as the culprit. As expected, Aurora52 nightlies don't reproduce since this change is still ifdeffed Nightly-only. Matt, I can probably create a stripped-down version of my profile to send you if it helps debug. Let me know.

Interesting Ryan. Yours is the first with this issue that I've seen that's not a GTX card. If I noted properly all the other GPUs listed here are GTX which connect it to bug 1318235 (a dependency of bug 1288618 ). In the end is seems that the new video decoding process could break VP8/VP9 Webm decoding for some GPUs.

It's a GM107 GPU in case that helps.

Tracking 53+ for this regression which affects youtube.

Can someone please test this build and see if it fixes the issue: https://treeherder.mozilla.org/#/jobs?repo=try&revision=385e822dc4e27f3d24f1d2bc3ab57e13435222f6

Still reproduces for me.

it hasn't finished building yet, so which build did you try?

The Taskcluster builds are usable.

Tried the build mentioned above by Matt Woodrow, still fails for me.

Previously, creating a RemoteVideoDecoder was infallible (as long as IPC was still up), and we did the CreateVideoDecoder work as part of Init. This moves the CreateVideoDecoder work to the constructor, and makes it sync, so that failures are reported immediately. The previous approach (making SupportsMimeType more accurate) didn't work, because WMFVideoMFTManager rejects VP8/9 streams if we failed to negotiate a hardware decoder [1]. This is hard/impossible to detect in SupportsMimeType since it will depend on the resolution/fps. [1] http://searchfox.org/mozilla-central/source/dom/media/platforms/wmf/WMFVideoMFTManager.cpp#474

Comment on attachment 8812635 [details] [diff] [review] Make PVideoDecoder's ctor sync and fail if CreateVideoDecoder Review of attachment 8812635 [details] [diff] [review]: ----------------------------------------------------------------- I don't know much about ipdl, but the logic behind it is right. It does make me wonder if we shouldn't simply combine Init and CreateDecoder into a single asynchronous API. So that when you call CreateDecoder you're given a promise, and the decoder returned would always be initialised and usable immediately.

I can still reproduce on a fresh build off m-c tip :(. Setting media.gpu-process-decoder back to false results in functional playback again.

I take that back, I think my build got messed up during packaging. I just rebuilt and retested and things appear to be working with media.gpu-process-decoder set to true!
