What function does YouTubeToMP3Process.exe perform?
It does everything that YT-DLP normally does because it is YT-DLP. YouTubeToMP3Process.exe is a customized YT-DLP that simply contains two additional DVDFab-related options. One will continue to download on error, and the other notes where the DVDFab cache is located. Load up your Windows Command (C:\Windows\system32\cmd.exe) and go to C:\Program Files\DVDFab\StreamFab\YouTubeDL. Then type
YouTubeToMP3Process.exe --help
This will list all the options. Compare them to YT-DLP, and they are identical except for the two additional DVDFab options. You can see the version of YT-DLP that it is based on by typing
YouTubeToMP3Process.exe --version
There is also another option you could try, and that is
YouTubeToMP3Process.exe -U
That option will update the program based on the latest stable release of YT-DLP. In the past, it would refuse to update it, but now I see it is working for me now. I'm amazed. Wow! I'm going to have to look into this more. It might have been because I did something on my end and may not work for you, like it didn't work for me in the past. It's been a long time since I played around with YouTubeToMP3Process, and so they might have tweaked it since then.
