[FFmpeg-devel] [PATCH] avcodec/libx264: bump minimum required version to 160
Niklas Haas
ffmpeg at haasn.xyz
Fri Apr 5 20:44:52 EEST 2024
From: Niklas Haas <git at haasn.dev>
This version is four years old, and present in Debian oldstable, Ubuntu
22.04 and Leap 15.1.
Allows cleaning up both the configure check and the file substantially.
In particular, this is motivated by the desire to stop relying on
init_static_data.
