Submitted By: Marty Jack (martyj19 at comcast dot net)
Date: 2022-07-23
Initial Package Version: 5.1.0
Origin: Rediffed from ffmpeg-5.0.1-api_addition-1.patch
Upstream Status: Not accepted
Description: The ffmpeg upstream is not willing to take this as a
permanent fix and suggests that Chromium should change to keep the
information locally to Chromium. Until that happens it appears
that many distros are carrying this patch as a temporary
expedient to allow building with system ffmpeg.
