Hi everyone, we have automatic thumbnail generation turned on for our application, but unfortunately the thumbnails are not showing up for videos uploaded from the SendBird dashboard’s moderation tool.

This is a pretty big deal for our use-case because we want to always display a video thumbnail for our iOS chat interface whenever possible. Any advice?

Hi @jurvis could you share the screenshot of your moderation setting in the dashboard that is blocking the thumbnail to be shown?

Thanks,

Hi Eric,

I cannot seem to find any moderation settings, but here is a screenshot illustrating what happens when I upload a video from the SendBird dashboard:

When retrieving messages via the SendBird iOS SDK, the array of thumbnails in SBDFileMessage is also empty.

We are also experiencing a similar issue with Video thumbnails with the iOS SDK and also have thumbnail generation switched on in our dashboard. Specifically it seems to be happening with .mov video files - when we send a .mov video file in a chat, we don’t get any thumbnails generated. Our code previously worked with mp4 files.
