ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Tue Mar 25 11:56:50 2025 +0200| [d256118b7e622c07167bbe044daba05c2326a6e3] | committer: Martin Storsjö

videotoolbox: Fix building with older SDKs

The kVTVideoDecoderReferenceMissingErr constant was only added
in the macOS 12 and iOS 15 SDKs. Use a hardcoded value instead
of the named constant, to fix building with older SDKs
after c6214b0d691566c7cb0f2ff5be08a24c3534e5bb.
