Use /tmp directory for frag and .vtt files

[asgh]

I sometimes see leftover --Frag17 and -.ru.vtt files in my home directory. I assume it's from me interrupting youtube-dl during a download.

Can you use the /tmp (TMPDIR) instead for those files?

Or a parameter that enables to choose temporary files’ folder/directory/path.
I would like to use my %TEMP% folder for those fragments, as it’s on an SSD, faster drive.

The way I want this to work is that you can specify the intermediate folder, what are the plans on this? As it would be good if it also could move after task done or after each video and you could decide.

I would also like to see a configurable temporary file folder, audio+video merging would work so much faster if source files were on a separate filesystem.

I would like to see this as well, it would be useful to download videos to a folder monitored by Serviio without manually moving them. youtube-dl sometimes fails to delete the temporary files after merging because Serviio opens them for a few seconds.

Using the current working directory for temporary files is never a good idea. youtube-dl should at least use the temporary folder defined by the system.
