Description wurstsemmel 2020-05-27 18:30:35 UTC

Description of problem: Gnome Videos (totem) does not play H.264 video from disk with gstreamer1-plugin-openh264 from repository fedora-cisco-openh264. According to [1] this should be possible since Fedora Workstation 31.

Version-Release number of selected component (if applicable): gstreamer1-plugin-openh264-1.16.2-1.fc32.x86_64 and openh264-2.1.0-1.fc32.x86_64

How reproducible: Always

Steps to Reproduce:
1. Make sure to remove gstreamer1-libav (repository rpmfusion-free)
2. Make sure to install gstreamer1-plugins-bad-free (repository fedora)
4. Install gstreamer1-plugin-openh264 (repository fedora-cisco-openh264)
5. Open H.264 video from disk [2] with Gnome Videos

Actual results:
Gnome Videos does not play the video due to missing codec. Installing gstreamer1-libav solves the issue.

Expected results:
Gnome Videos should play the video with gstreamer1-plugin-openh264.

Additional info:
Potentially this issue is related to https://bugzilla.redhat.com/show_bug.cgi?id=1839971, where I describe that mozilla-openh264 plugin for WebRTC in Firefox is not working. My rough guess is that openh264 may not work for gstreamer in Gnome Videos and for WebRTC in Firefox. H.264 playback with ffmpeg-libs in Firefox works fine.

OS: Fedora Workstation 32 (with Gnome)

Comment 1 Fedora Program Management 2021-04-29 16:28:15 UTC

This message is a reminder that Fedora 32 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '32'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 32 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 wurstsemmel 2021-04-30 14:24:58 UTC

I removed gstreamer1-libav on Fedora 34 and can still play the video file from disk.

Therefore, I cannot reproduce the bug on Fedora 34. I will close the bug report.
