Reading iPhone MOV throws File format could not be determined

[rnedumpurath]

Starting around iOS15, I've been getting the "File format could not be determined " exception when trying to read the metadata of a video file of a Live Photo. A Live Photo on an iPhone creates an HEIC image file as well as a video file. The video file from that package is what is throwing the exception. I'm attaching a sample video file that should recreate this exception. Tested with .NET 7 running MetadataExtractor 2.8.1.

Yes, I get this as well. Apple don’t like Windows :(

I’d use this library if this was fixed, otherwise it’s of no use to me as Apple files are prolific.

I can provide video files if that helps with the development of this capability

I would add that “throwing an exception” is very bad for performance. If I’m getting the data for a thousand files and 20% are Apple videos, this package hits a wall performance wise. It should return a code instead. Exceptions are for unexpected errors if all goes wrong, not for known, expected things you’re checking for.

I think Apple are using hevc encoding now
