Description of your issue, suggested solution and other information

I am trying to develop an aplication with youtube-dl. When downloading a video to a very nested subfolder in order to reach the maixmum path length youtube-dl outputs the error

ERROR: unable to open for writing: [Errno 2] No such file or directory: 'South Park_December 17, 1997_1_0110_South Park 110 - Mr. Hankey, der Weihnachtskot - 1. Ak-e6039bb4-ed00-11e0-aca6-0026b9414f30.mp4.part-Frag0.part'

(Used southpark for example). The process then exits with error code 0 (success) indicating that everything went well. I have also tested this beahivour with mistyped url's (404). Checking for the exitcode is therefore not working. Also if i start youtube dl within a c# process i cant get the error output. If i redirect all output it is still visible within my console window so it seems like the error message is returned some other way.

How can i catch all errors programmaticaly when using youtube-dl and why is the exit code always 0?

Most likely you're getting error code of wrapping process not youtube-dl.

[bumbummen99]

I have got it working by starting youtube-dl directly as a Process and setting the WorkingDirectory first. That way i could avoid using cmd.exe and get the right exit code. -o does not work for multiple files.

-o does not work for multiple files.

Not true.
