after the update I can not upload video files, what could it be?
Please make sure that you uploaded the patch, not the full version, if you uploaded full version then ffmpeg binary may be overwritten. I would suggest to check if you are using the correct ffmpeg binary for your OS (by default ffmpeg for Linux is provided) and permissions are correct - you can recheck permissions here:
Admin panel > Tools > Host Tools > Permissions.

It shouldn't be related to the patch, this patch doesn't change anything related to video files uploading.

If you see more still have problems, please describe it in details in the forum:
