Of course I read messages above my reply. File YoutubeUi.pyo is in hexadeci code.
For normal conversion i use soft "Easy Python Decomplier", but soft can not conversion to back on hexadeci code.
I don't know how make shell script for change the api key directly inside of the file. Thank s3n0
Just need to only change "apy key", or change next "Client secret" "Client ID"? I just changed "apy key" and youtube works.
thanks to all
