Bug Description

Wanted to send a video (.mp4; ~ 2 MiB) to a contact. However, it does not work and I get the following error:

I've sent the video to *SUPPORT (perhaps it helps with debugging). Note that sending as file works, but not sending as video.

Steps to Reproduce (for bugs)

The Android app uses several ways to get a thumbnail of the video including attempting to render a frame via the MediaMetadataRetriever. In the unlikely event that everything else fails (what seems to be the case here), it falls back to a default icon. Due to a bug, this default icon was not generated on older Android versions. This has been fixed now. Expect the fix in the next major release of the app.
