Reproduced both on version 1.6.2 and the current development snapshot(revision bf4cb4abad4e).
as explained in the comment, av_register_all still required for ffmpeg3. you could perhaps retouch with something like
#if ffmpeg version < 4
av_register_all();
#endif
Build output:
Refer Caffe2 uses FFMPEG functions that are deprecated in FFMPEG 4.0 and gone in 5.0 · Issue #72254 · pytorch/pytorch it seems that the av_register_all function call is obsoleted since FFmpeg 5.0.
