Description

I want to download a youtube video via http proxy by using aria2c as the external downloader. However youtube-dl cannot recognize aria2c and still downloads by ffmpeg. I have already added my aria2 directory to PATH environment variable, and aria2c works fine on its own.

aria2 version 1.35.0
youtube-dl version 2020.06.16.1

aria2c does not support DASH.

aria2c does not support DASH.

Thank you. So what kind of external downloader could I use for youtube video downloading?

[dstftw]

None for DASH.
