In Fedora 26 clean installed, I run into sites using H.264 content that produces a "no video with supported format and MIME type found" in Firefox as preinstalled; and also Chromium from Fedora repo.
Is this page still valid? https://fedoraproject.org/wiki/OpenH264
Even doing everything on that page, I'm still running into the following confusion:
1. about:support in Firefox Compositing Basic Hardware H264 Decoding No; Failed to create H264 decoder Decision Log HW_COMPOSITING blocked by default: Acceleration blocked by platform OPENGL_COMPOSITING unavailable by default: Hardware compositing is disabled
2. Numerous examples of site that won't play content http://www.html5videoplayer.net/html5video/mp4-h-264-video-test/ http://abcnews.go.com/US/video/h264-test-16x9-medium-10415218
3. http://html5test.com/index.html This says H.264 is not supported
Are there bugs I should file? This is all pretty confusing.

OpenH264 is of limited use because it works for WebRTC only. It cannot play MP4 videos. Someone from Red Hat was assigned to work on this at one point, but I guess that got deprioritized?
It would probably be higher priority if we had some feasible path to supporting AAC audio. Being able to play the video but not the audio is not going to be very useful. I have not heard any hint that a solution to this is on the horizon, so I'm not very optimistic.

I believe it works for playing back videos, but is blocked by SELinux.

Firefox does not use OpenH264 to play any video, it's not implemented on Firefox side because OpenH264 is not usable for that and there's also missing audio codec. Firefox uses ffmpeg for H264 video playback.

And from WebKit side: WebKit only uses GStreamer, so there would have to be a GStreamer plugin for it.

In the fedora-cisco-openh264 repo there's both gstreamer1-plugin-openh264 and mozilla-openh264 packages that are suppose to work with the respective browsers.
Just to follow-up a bit on this thread in general. Wim Taymans was assigned to work on it, but simply has not found time to do so. So what I am pursuing currently is have Centriclular (http://www.centricular.com/) do the work for us, just need to shake enough piggybanks first to make it happen :)
As for AAC audio, yes that is a problem, but a lot of Webm files for instance use H264+Vorbis afaik. But I am looking into what can be done with AAC support too going forward.

WebM is usually VP8 or VP9 video with Vorbis or Opus audio.
Not quite sure what one would gain by mixing H264 + Vorbis, apart from making sure it works equally badly on all platforms :)

Actually play nothing is better than video only as it is easier to figure out what's going on.
