2a68d945cdadded const version of a callback functions but didn't enable them. They were guarded by a version check:2a68d945cd/libavformat/version_major.h (L48)So for anything LIBAVFORMAT_VERSION_MAJOR < 61 they are not enabled therefore they are enabled for everything >= 61.0.100. See https://github.com/elsid/openmw/actions/runs/10255993574/job/28374152796 as example of failure when building with 60.16.100.
