Hi, I add this plugin into my project and set the start capture funtion when the game starts. It will crash and the callstack is below.

Hello author, I found the cause of the crash, it is because I used "Get recommend video file name". If I specify to write to a certain file, then there is no problem, but if I don't specify, it will still crash. Is there anyway to fix? Thank you.

Few things to check

  1. print the result of Get recommend video file name and see if the path seems to be correct (but don't begin capture so it doesn't crash)
  2. See if the game has permission to write at that path
  3. You can make your own file path algorithm ( for example save videos at the project folder )

Based on your country I think there can be a folder name with non English names in the path and that can also cause the crash !

Thanks，I will check it.

I found out that the Capture folder must exist in My Documents.
