Question:

I use this command (*) to download the best dash quality of some youtube videos:

youtube-dl -f 137+140 http://www.youtube.com/watch?v=3JZ_D3ELwOQ

*Source: http://unix.stackexchange.com/questions/272868/download-only-format-mp4-on-youtube-dl/272934

Sometimes this command creates lots of .Frag-files in the home folder - and sometimes not. It happens with large videos and shorter ones but not consistent. Crawling the readme gave no hints on that. So can anybody explain why youtube-dl creates this fragments?

cheers

Some videos served in fragments. In this case frag files are created.

I'm also curious about this. Sorry if i ask a bit more here. Just want to know, Then when a video served in fragments, it will be downloaded as separated frag files first by youtube-dl? or is it possible to download it with no frag files?

@linglung See #9937

Can you set maybe a run time working dir for youtube-dl to use till its ready to copy the finished concatenated file whatever the main env $CWD was when the initial command was run?

@brokendash See #10993. Before that is implemented, you can use --exec
