I am trying to figure out why I am seeing "an error occurred" when trying to play back HTML5 video from Youtube and a segmentation fault crash when loading the HTML5 test videos at http://www.quirksmode.org/html5/tests/video.html .

I only see "segmentation fault" in the terminal with no other clues to go on. I have followed Google's steps for the Youtube error. I am not using any addons. I also have tried two different computers with the same problem.

How can I continue troubleshooting?

You can check at https://www.youtube.com/html5 to see if your Linux system install fully support html5. I get seven blue check marks.

I believe one does not need Gstreamer packages anymore in the last few Releases of Firefox however you still need ffmpeg.

However since you appear to be using a old Firefox 38.8.0 version (third-party) you likely do need Gstreamer packages on your Linux distro to play HTML5 video.

Thanks for the quick reply. I only get 2 of 6? check marks. H.264 support crucially is missing.

As far as I know gstreamer is installed because I had to install many gstreamer packages to enable HTML5 playback on qupzilla which ended up being too slow. Just so you know even with a new install without these packages the result is the same.

So currently I am still at a loss.

edit: I believe H.264 support was going down the wrong path. Apparently with the HTMLVideoElement and WebM VP8 it should be working.

edit: I am using Debian Linux and have tried Iceweasel 38.8.0 and Firefox-ESR 45.3.0 with the same result.
