Steps to reproduce:

2. Generate thumbnail data on any video with 1280x720 resolution (i.e. https://user-images.githubusercontent.com/1192455/137946599-3fbcd8fd-ff71-44d4-a19a-beac029f9b7a.mp4)
3. The actual behaviour:
   • For iOS, thumbnail data is null.
   • For Android, thumbnail data is generated correctly.

flutter doctor -v

Same issue here error:

error:Error Domain=AVFoundationErrorDomain Code=-11832 “Cannot Open” UserInfo={NSLocalizedFailureReason=This media cannot be used., NSLocalizedDescription=Cannot Open, NSUnderlyingError=0x2823dcab0 {Error Domain=NSOSStatusErrorDomain Code=-12431 “(null)“}}

I can send an .mp4 video that is causing this issue every time

I met the same error, solved it by stack Overflow: https://stackoverflow.com/questions/43548529/get-last-frame-from-video, open iOS code, 'remove requestedTimeTolerance'，then is ok。

The same problem when creating thumbnail from video MOV shortly ( around 2 -5 seconds)

couldn't generate thumbnail, error:Error Domain=AVFoundationErrorDomain Code=-11821 "Cannot Decode" UserInfo={NSLocalizedFailureReason=The media data could not be decoded. It may be damaged., NSLocalizedDescription=Cannot Decode, NSUnderlyingError=0x280fed950 {Error Domain=NSOSStatusErrorDomain Code=-12911 "(null)"}}

This does remove the error but at the same time some of the thumbnails come out to be black.
