Big file (>5Gb) unable to be cut

[ofaurax]

Happy new year!
I'm trying to cut a 5.6Gb file, and I get an error "Muxer Can't open" (Muxer Ne peut pas ouvrir).

Here are traces:

I'm using latest 2.8.1 AppImage.

The file comes from a camera and plays correctly, so I assume the file is not corrupt, but I'm not sure if we can really trust the encoder.

Is this a bug or a corrupted file?
Is there a way to bypass this problem?

Thanks in advance

1. Do not use MP4v2 (libmp4v2) muxer, use MP4 (libavformat) instead.
2. Anything 2.8.1 is ancient, please verify any issue you find with the latest available 2.8.2 nightly.
