💡 Summary

Video thumbnails are not generated since upgrading to 12.111.0. It worked with 12.110.1 after applying #8696.

🥰 Expected Behavior

Video thumbnails are generated.

🤬 Actual Behavior

Video thumbnails are not generated. I get this in the log:

INFO 1  [drive register]        {"size":11388127,"md5":"ca3a79307344819607654b1ba7d6eb62","type":{"mime":"video/mp4","ext":"mp4"},"warnings":[]}

This is the answer from the API:

The patch in #8820 fixed that error, but now i get “Input file contains unsupported image format”. I also tested it with a video/mp4. I'm pretty sure these videos created with SimpleScreenRecorder worked before, although i can't find proof at the moment. ffmpeg -i test.mp4 -frames:v 1 thumbnail.jpeg works with the file.

Perhaps temp filename must have a .png extension.

Thanks, the patch in #8825 works for me. 💖
