Confusing error when using video/mov mimetype for uploading .mov files

[karcsesz]

Describe the current behavior

Apparently on some Windows installs (like my friend's live media production machine) the system-wide mimetype registry has a nonstandard record for .mov files under HKEY_CLASSES_ROOT.

As web browsers defer to this registry to figure out the uploaded video's mimetype, the upload request sends video/mov instead of the standard video/quicktime that PeerTube is currently set up to accept, therefore the user is faced with an error telling them their format isn't supported even though .mov will be listed as a supported extension.

Steps to reproduce

1. Install an application that changes the .mov mimetype to video/mov (not sure which one it is yet, but my hunch is Premiere)
2. Try to upload a file with .mov extension to PeerTube
3. Get rejected for invalid file type even though the error clearly lists .mov as a valid format

Describe the expected behavior

PeerTube either returns a different, more descriptive error, or caves and accepts video/mov mimetype for .mov files as well as video/quicktime even though it isn't standard, as this seems to be a somewhat common issue.
Another project that ran into this: immich-app/immich#1913

It might also be nice to log the rejected mimetype with the returned error to simplify troubleshooting similar issues.

Additional information

• PeerTube instance:

  • URL: https://pt.thishorsie.rocks
  • Version: v6.3.2
  • NodeJS version: v18.19.0
  • Ffmpeg version: 5.1.6-0+deb12u1

• Browser name, version and platforms on which you could reproduce the bug: Windows 10, both Chrome 129.0.6668.90 and Firefox 131.0.2, probably every browser that relies on OS mimetypes
