#199 Can't tag MP4's?

[molnizzle]

I can't seem to write tags to MP4 files. When I click "save," the fields all go back to being blank. I'm using the latest version (3.7.1) with all settings at default. Just downloaded the application to tag MP4's.

Strange, never heard of this.

• Which operating system are you using?
• Are the files on a normal hard disk or on a network drive?
• Does it happen with both metadata plugins supporting MP4 (Mp4v2Metadata is used instead of TaglibMetadata when checked and higher in order)?
• Does it work with other file types like MP3, Ogg or FLAC?

• macOS Mojave
• Local disk, main boot SSD
• Not sure on that, I haven't changed any settings since I don't really understand what they mean
• FLAC and AAC worked fine. Haven't tested others.

Could you please try if you are able to write tags to the following example file
https://github.com/robovm/apple-ios-samples/blob/master/avTouch/sample.m4a

If it works with this file but not with yours, can you provide me an example file to reproduce the issue?

I am closing this ticket because no further information has been provided and nobody else seems to have seen this bug.
