Piwigo 2.10.2, git master: Very big mp4 videos not imported

[Catfriend1]

Hi,

I'm running a debian 10 buster VM with piwigo 2.10.2 and the recent git master of this plugin (piwigo-videojs). I can import my videos now as all required tools are installed. I can watch them on the web gallery. But there's one video, around 1.8 GBytes of size from a holiday which isn't shown. Resyncing piwigo, double checking file read permissions and resyncing in piwigo-videojs does not help here. I'm sure the mp4 file can be accessed and it was on the green "successfully imported" list. How to debug this?

Thank you.
