This means that plugins with H.264 enabled require an internet connection at install time that does not block the download. Opus or another free audio codec could also be used with h.264 video. Twitter) Video decoding via OpenH264 could also be useful to provide a consistent codec implementation for video, even if a platform audio codec is needed. The dynamic library MUST be downloaded and installed while the plugin is installed, not when it is built. Some services are re-encoding animated GIFs as audioless video using h.264. Please note that OpenH264 cannot be packaged into the plugin build itself. To add the H264 codec download 'openh264-1.6.2.

In order to avoid either Temasys or our clients being liable for royalties, we use a dynamic library built, implemented and distributed by Cisco called openH264 (The same system that Firefox uses). Now H.264 usually requires royalties to be paid. Please note that the openH264 dll is neccessary for the plugin to work. Temasys uses openH264 in the plugin to add support to H.264. H.264 is a video codec natively not implemented in libWebRTC. One such feature is H.264 enabling which can be requested at the time of a plugin build.

Sadly the created temporary files arent removed. As noticed the ProductAddonChecker downloads the video codec plugins after some minutes of the first start. Our commercial plugins offer support for features that are not part of the WebRTC specification which you may choose to include or exclude at build time. Bug 1467700 - Disable download of OpenH264 and Widevine plugins for Marionette and geckodriver. Modified on: Wed, 23 Oct, 2019 at 3:31 PM We will reconsider this once support has been added.
