Ogg: audio skip and gap when playing opus stream containing a METADATA_BLOCK_PICTURE

http://mbsoft.net:3760

this is a live opus stream that starts a newstream (containing a METADATA_BLOCK_PICTURE) everytime the on air title change so the listeners can see the current cover art.

all versions of vlc have problems of audio skips and gaps at track change although the cover art is correctly updated in the vlc window. Tested 3.x and 4.x

Could you please improve the vorbis demuxer in order to have a gapless experience?
