[02/25/20 12:49:37] WARNING: Falling back on generic information extractor.
[02/25/20 12:49:37] ERROR: [WinError 183] Cannot create a file when that file already exists: 'C:\\Users\\HP I5\\Videos\\4\\master.temp.mp4' -> 'C:\\Users\\HP I5\\Videos\\4\\master.mp4'

This shows that it is creating same output file name when 2 or more videos downloading at a time.
How to solve this error by automatically giving different output file name.
