Closed frankplow closed 5 months ago

frankplow commented 5 months ago

IS_SAME_MV requires motion vectors to be aligned to a multiple of 8 bytes: https://github.com/ffvvc/FFmpeg/blob/ae5efc8e4b4d3ea0ce673d0ee69e425487591d42/libavcodec/vvc/vvc_mvs.c#L28 This PR adds the same requirement to the definition of MvField. It fixes errors with UB sanitizers.

thank you please send it to upstream too. If you have a sanitizer error link, maybe you can attach it to commit log
