Comment (by kagami):
Hi.
I'm still getting error `Symbol not found:
_kCVImageBufferColorPrimaries_ITU_R_2020` when trying to run latest ffmpeg
on Maverics built on Sierra. libavcodec.dylib still includes references to
such symbols:
{{{
$ nm -g libavcodec.57.dylib | grep R_2020
U _kCVImageBufferColorPrimaries_ITU_R_2020
U _kCVImageBufferTransferFunction_ITU_R_2020
U _kCVImageBufferYCbCrMatrix_ITU_R_2020
}}}
Do you know what might be the reason of that? These symbols are
[[https://developer.apple.com/reference/corevideo/kcvimagebuffercolorprimaries_itu_r_2020|not
available in 10.9]] and linker obviously fails.
Problem goes away when I use `--disable-videotoolbox` configure option.
