[FFmpeg-devel] [PATCH 3/4] avcodec/svq1: Set hidden visibility

[Andreas Rheinhardt]

The encoder uses ff_svq1_inter_mean_vlc + 256 and setting
hidden visibility allows to bake this "+ 256" into the
general offset of ff_svq1_inter_mean_vlc and the code
accessing it.

For certain arches, this is also required for the compiler
to not produce overtly pessimistic code that can't be fixed
up by the linker lateron.
