The VTRegisterSupplementalVideoDecoderIfAvailable is available since
macOS 11 according to the
header annotations:
VT_EXPORT void VTRegisterSupplementalVideoDecoderIfAvailable(
CMVideoCodecType codecType ) API_AVAILABLE(macosx(11.0))
API_UNAVAILABLE(ios, watchos, tvos);

#if (!TARGET_OS_IPHONE && MAC_OS_X_VERSION_MAX_ALLOWED >= 110000)
decoder_spec =
videotoolbox_decoder_config_create(videotoolbox->cm_codec_type,
avctx);
if (!decoder_spec) {
