I have very little experience with mailing lists, my apologies if this reply does not end up where it is supposed to be.
The Apple developer docs say that AVMediaType is a struct, but it looks seems that in reality it is typedef-ed to NSString*, just with an extra specifier NS_EXTENSIBLE_STRING_ENUM. Thus the constants introduced in 10.7 are NSString* both before and after 10.13 and it would likely not be a problem if this typedef were to be compiled in on 10.13+, but I want to avoid it if possible. I agree that *_MAX_ALLOWED is probably what I was looking for and wrote a simple test program using the 10.12 and 10.13 SDKs to verify that. Using AVMediaType and compiling with the 10.12 SDK fails. Compiling it with the 10.13 succeeds and runs as expected on my 10.9 system. Compiling it with AVMediaType typedef-ed to NSString* and SDK 10.12 also works as expected. Thanks for putting me on the right track! I will try to submit a new version of the patch as a reply to this thread. Please let me know if I should submit it as a new thread instead. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
