# (NULL_IF_CONFIG_SMALL in libavcodec/codec_desc.c) and the profile name tables
# (libavcodec/profiles.c). Without them mpv based players (stats overlay, Cine)
# show no codec and no "HW:" line, which looks like hardware decoding is off.
# profiles.c has to be patched together with codec_desc.c, because codec_desc.c
# refers to the ff_*_profiles tables and the link of the programs fails without
# them.
