Description

I use youtube-dl in iOS and call youtube-dl through Python-Apple-Support. So far, it can be used perfect, but it will generate warning and error logs. I don’t know what the reason is? Are some of my options not set correctly? ? These logs are output on the real device.

These logs look like youtube-dl is writing to the cache in some directories, but the written directories do not have permissions. Are some APIs able to set other paths?

I found this option --no-cache-dir but I don't know how to set it programmatically.

Best Regards.

You have no permissions to create directory .cache in your ~.

@dstftw Yes I know that, is there any api to change the path when programming ?

[dstftw]

Set XDG_CACHE_HOME env variable.

@dstftw Thank you. It works.
