Snapshot FFmpeg n7.1 (release tag) с применённым patch'ем для cuframes input format. Используется как FFMPEG_REPO_OVERRIDE в NickM-27/FFmpeg-Builds fork для статической сборки patched binary под Frigate (Debian 12 / glibc 2.36). Apply changes: + libavformat/cuframesdec.c (новый — реализация демуксера) M libavformat/Makefile (CONFIG_CUFRAMES_DEMUXER target) M libavformat/allformats.c (extern declaration) M configure (--enable-libcuframes option + dep check) Patch source: https://git.goldix.org/gx/cuframes (filter/ffmpeg-7.1-cuframes-demuxer.patch) History сброшена (snapshot вместо fork) потому что upstream shallow clone не позволял push в gitea. Полная история FFmpeg — на github.com/FFmpeg/FFmpeg n7.1.
