Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
Date: 2018-05-12
Initial Package Version: 1.2.4
Upstream Status: Defunct
Origin: Gentoo
Description: Accumulated fixes up to and including building with ffmpeg-4

From gentoo, their libav-9.patch, ffmpeg2.patch, CVE-2016-2399.patch,
ffmpeg29.patch, ffmpeg4.patch, and seds to files lqt_ffmpeg.c, video.c,
audio.c in plugins/ffmpeg/ to change CODEC_ID to AV_CODEC_ID.

Build-tested only.
