Initial Package Version: 5.0.1
Origin:                  Arch Linux
Upstream Status:         Unknown
Description:             Adds the av_stream_get_first_dts() function so that
                         QtWebEngine (and other Chromium forks) can build with
                         system ffmpeg when the version is above ffmpeg-4.4.
