[FFmpeg-devel] [PATCH] avcodec/videotoolbox: Fix undefined symbol with minimal configuration

[lance.lmwang at gmail.com]

From: Limin Wang <lance.lmwang at gmail.com>

Please reproduced with the following minimal configure command:
./configure --enable-shared --disable-all --enable-avcodec --enable-decoder=h264 --enable-hwaccel=h264_videotoolbox

You'll get below error:

Undefined symbols for architecture x86_64:
  "_ff_videotoolbox_vpcc_extradata_create", referenced from:
      _videotoolbox_start in videotoolbox.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
