Description wurstsemmel 2020-05-26 06:49:02 UTC 
Description of problem: Firefox OpenH264 Plugin for WebRTC (mozilla-openh264 from repository fedora-cisco-openh264) is not recognized or does not work. Instead, after pressing "Check for Updates" in Settings -> Add-Ons -> Plugins, the Mozilla-Plugin is downloaded and installed. According to [1] the Mozilla Plugin should not be downloaded automatically in Fedora due to licensing issues.


Version-Release number of selected component (if applicable): firefox-76.0.1-1.fc32.x86_64 and mozilla-openh264-2.1.0-1.fc32.x86_64. mozilla-openh264 is installed from fedora-cisco-openh264.


How reproducible: Always.


Steps to Reproduce:
1. Install mozilla-openh264 from fedora-cisco-openh264 as explained in [1]
2. Create a Firefox fresh profile, activate the WebRTC H264 Cisco Plugin in Settings -> Add-Ons -> Plugins
3. Check about:plugins. It shows:

    Datei: system-installed
    Pfad: /home/username/.mozilla/firefox/d1qgjuys.xxx/gmp-gmpopenh264/system-installed
    Version: system-installed

4. Test functionality https://mozilla.github.io/webrtc-landing/pc_test.html (check Require H.264 video) -> "No H264 found in the offer!!!"
5. Click "Check for updates" in Settings -> Add-Ons -> Plugins and wait some time
6. Do the WebRTC test again -> "HIP HIP HOORAY"


Actual results:

WebRTC test responds with "No H264 found in the offer!!!" as long as it is shown as "system-installed". It works after step 5 with the Mozilla Plug-In (excerpt from about:plugins below).

    Datei: 1.8.1.1
    Pfad: /home/username/.mozilla/firefox/d1qgjuys.xxx/gmp-gmpopenh264/1.8.1.1
    Version: 1.8.1.1

Expected results:

a) WebRTC test should work with system-installed plugin and b) should not be replaced by Mozilla-Download after pressing check for updates in Settings -> Add-Ons -> Plugins.

Should be already fixed in latest updates by https://bugzilla.redhat.com/show_bug.cgi?id=1883006
Comment 3 wurstsemmel 2020-10-13 18:55:07 UTC 
Yes, it works with the latest updates with system-installed plugin (mozilla-openh264).

Thanks for the great work! (Please close the bug or let me know if I should/can do it.)
