Description
Some files with certain codecs might not be correctly decoded via the deprecated APIs.
The new API has avcodec_send_packet and avcodec_receive_frame .
MPlayer currently uses avcodec_decode_video2 and avcodec_decode_video4 .
It can sometimes be seen for example with AV1 video:
mplayer av1_file.mkv [...] [libdav1d @ 0x576d1840]The deprecated avcodec_decode_* API cannot return all the frames for this decoder. Some frames will be dropped. Update your code to the new decoding API to fix this [...]
Also should the deprecated APIs get removed at some point in time, it could probably not be fixed quickly.
