[FFmpeg-devel] [PATCH 08/39] avcodec/h261dec: Don't initialize unused VLCs

[Andreas Rheinhardt]

The H.261 decoder uses only the very first VLC of ff_h261_rl_tcoeff,
so only initialize this one. Saves 68448B from the .bss segment; in case
the decoder is actually used, this amount of memory is saved.
