Of all these VLCs here, only VLC.table was really used after init, so use the ff_vlc_init_tables API to get rid of them. Also combine the ff_msmp4_dc_(luma|chroma)_vlcs as well as the tables used to generate them to simplify the code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
