Git pushed a commit to branch release/7.1 in repository ffmpeg. commit 39ee683e8fd1ef6535472c82c54c927520c52d1d Author: James Almer <jamrial@gmail.com> AuthorDate: Fri Feb 27 10:41:31 2026 -0300 Commit: James Almer <jamrial@gmail.com> CommitDate: Fri Feb 27 12:27:41 2026 -0300 avformat/mov: fix cases where we discard iamf packets from enabled streams Given the entire iamf struct is inside a single Track, if the first iamf stream (which is the one sharing the index and id from the Track) was to be disabled, then packets from every iamf stream would be discarded. Fix this by actually going through the entire iamf Sample and discarding those from the disabled streams only.
