As reported by forum user tygerbug, trying to run a current ffmpeg binary on osx shows:

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 ​not available in 10.9 and linker obviously fails.

Problem goes away when I use --disable-videotoolbox configure option.

Which version did you test?

[kagami]

I built commit 7e4f32f4e4b93c95dcc872cb844c5548e69f352e with Homebrew on Sierra 10.12.3 and tested it on Maverics 10.9.5.

I see the issue. Difficult to test on my setup.
