The issue you are facing:
Uploading mp4 videos from Android app fails. Produces “Erreur inconnue” (Unknown error). In notifications, it says “Echec de l’envoi” (Upload failure), “Not Acceptable”.
This is unrelated to file size, the error occurs even with small (e.g. 2.1 MB) mp4s.
I don’t see error log lines as in this issue:
I have uplaoded mp4 videos from the desktop app, which I can watch fine in the web interface. Also, I have uploaded photos from the Android app.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- In app, press “+” button to upload files.
- Select “Ajouter a Nextcloud > Televerser des fichiers” (Add to Nextcloud > Upload files).
- Select an .mp4 file.
The output of your Nextcloud log in Admin > Logging:
Version warning: Imagick was compiled against Image Magick version 1650 but version 1654 is loaded. Imagick will run but may behave surprisingly at Unknown#0
(The above is from an unrelated issue. I don’t see any output relating to this issue.)
