[FFmpeg-devel] [PATCH 2/2] avcodec/msmpeg4data: Mark tables as hidden

[Andreas Rheinhardt]

This e.g. allows compilers to bake the "+ 256" offset
used to access ff_v2_dc_(lum|chroma)_table into
the general offset; for certain arches this is also necessary
in order to avoid building suboptimal code.
