Hello,
I'm running OS X 10.9 and I'm not able to build FFmpeg dynamic libraries with
decoders disabled.
I use this configure command:
../configure --disable-yasm --enable-shared --disable-decoders
For FFmpeg 2.1.3, it fails with the following:
LD libavcodec/libavcodec.55.dylib
Undefined symbols for architecture x86_64:
"_ff_hevc_compute_poc", referenced from:
_hevc_parse in hevc_parser.o
"_ff_hevc_decode_nal_pps", referenced from:
_hevc_parse in hevc_parser.o
"_ff_hevc_decode_nal_sei", referenced from:

"_ff_hevc_extract_rbsp", referenced from:
_hevc_parse in hevc_parser.o

For FFmpeg HEAD from the git repository (git://source.ffmpeg.org/ffmpeg.git),
it fails with the following:
LD libavfilter/libavfilter.4.dylib
Undefined symbols for architecture x86_64:
"_av_dct_calc", referenced from:

"_av_dct_init", referenced from:
_init in vf_dctdnoiz.o

If I remove the --disable-decoders configure flag, then both FFmpeg 2.1.3 and
FFmpeg HEAD build fine. However I wish to use this option in order to enable
only a few decoders in my build, for legal reasons, thus this is a blocking
issue to me.
My OS:
