Is this error consistent for those videos? Are they special in any way? For example, are they the only videos that are larger than 1 GB or on the cloud?

It's small video(less than 10 seconds), nothing special compare to other successful call. I will record and save the video to devices then get its thumbnail. Most of the time will be successful, but will fail occasionally. By the way, even the thumbnail returns failure, but the related video can be played.

Hmm, is it possible that the recording you are saving to the device isn't fully saved while you try to get the thumbnail? Some operations can be asynchronous and it's possible that saving the recording is one of them. How about you wait 10 seconds after saving the video, just for testing purposes, and then fetch the thumbnail?
