what is the best way to generate a thumbnail image / poster for a video that is uploaded to UT?
I was thinking about using ffmpeg to generate a thumbnail from the uploaded video, but this might get costly on the server. and i dont like writing to the file system on the server as my own general rule. plus, this going to require uploading the thumbnail to UT after it is generated. I wish that UT automatically could create thumbnails for videos. But that might be asking too much. The other alternatives i was thinking of was AWS Lambda S3 solution or cloudfare. But that just defeats the purpose since I am using UT for all storage cases.
