- There was an issue with DVD menus. It is not a bug in avcodec but
avcodec outputs the first I frame with a latency of one (unless there is
an EOS). It is now OK in VLC as we insert an EOS when we detect a menu.
- avcodec has decoding issues with field pictures at least on some
samples I have (I only recently seen this issue while adding dxva2
Anyway, IMHO keeping both versions of a decoder even after their
priority order has changed for the first release is a good thing. It
allow to easily detect regressions due to the codec change and/or to
have a quick workaround.
