From the Search field type in 264 and a handful of options will appear.

Type about:config into the Firefox address/URL field and accept the warning.

You can do a simple test whether your H.264 works in RTC on this page (check Require H.264 video). $ sudo dnf install gstreamer1-plugin-openh264 mozilla-openh264Īfterwards you need open Firefox, go to menu -> Add-ons -> Plugins and enable OpenH264 plugin. Optionally you can specify full path via the environment variable OPENH264LIBRARY (not OPENH264LIBRARYPATH).

FFMPEG: tag 0x34363258/X264 is not supported with codec id 28 and format h264 / raw H.264 video Failed to load. $ sudo dnf config-manager -set-enabled fedora-cisco-openh264 When I do background subtraction on a video in Python using OpenCV, it works. Ths encoder option is vastly superior to default Software H.264 Encoder available in Man圜am in terms of quality and performance, for which reason we suggest using Cisco’s solution instead (as long as your hardware meets the requirements). Taking the source and building your own version of the codec doesnt convey the waiver. Cisco OpenH264 is a codec library used for encoding/decoding of H.264/MPEG-4 AVC video streams in real time. That effectively makes the codec have zero cost if it is obtained from Cisco. However, if it is not enabled for whatever reason, you can enable it: Cisco has generously offered its OpenH264 codec for the heavily patented (and strongly enforced) H.264 video format without passing on the MPEG Licensing Authority (MPEG-LA) fees. It is enabled by default since Fedora 33. This repository also contains OpenH264 plugins for gstreamer and Firefox. It contains OpenH264 binary built inside the Fedora infrastructure, but distributed by Cisco, so that the all licensing fees are still covered by them. Installation from fedora-cisco-openh264 repositoryĪ fedora-cisco-openh264 repository is distributed since Fedora 24 by default (if you have at least fedora-repos-24-0.5 package or newer). Due to it's binary nature, Fedora disables this automatic download. Upstream Firefox versions download and install the OpenH264 plugin by default automatically. The binary is released under this agreement from Cisco: The code source is available at under a BSD license. It does not enable generic H.264 playback, only WebRTC (see Mozilla bug 1057646).

This codec allows you to use H.264 in WebRTC with gstreamer and Firefox.

1.1 Installation from fedora-cisco-openh264 repositoryĬisco provides an OpenH264 codec (as a source and a binary), which is their implementation of H.264 codec, and they cover all licensing fees for all parties using their binary.
