commit 58052b484e584e6f30f84fc42a65ec9eba2f69cb Author: James Almer <[email protected]> AuthorDate: Fri Mar 6 10:28:52 2026 -0300 Commit: James Almer <[email protected]> CommitDate: Sat Mar 7 19:22:14 2026 -0300 avcodec/codec_desc: make LCEVC a video media type Every container signals it as such, and the data media stream type is too undefined and unsupported across the codebase that even if no standalone decoder can be present for it, it's preferable to it. This is technically an API break, but LCEVC support has been minimal until now so it should be safe.
