[FFmpeg-devel] [PATCH 3/6] avcodec/mpegvideodata: Mark tables as hidden

[Andreas Rheinhardt]

This e.g. allows compilers to bake the offset implied
by using ff_mpeg12_dc_scale_table[3] (as the SpeedHQ encoder
does) into the general offset; for certain arches this is
also necessary in order to avoid building suboptimal code.
