Resume a download

Ctrl+C interrupts a download.

A temporary .download file is kept in the output directory. If lux is ran with the same arguments, then the download progress will resume from the last session.

Auto retry

lux will auto retry when the download failed, you can specify the retry times by -retry option (default is 100).

Cookies

Cookies can be provided to lux with the -c option if they are required for accessing the video.

Cookies can be the following format or Netscape Cookie format:

name=value; name2=value2; ...

Cookies can be a string or a text file, supply cookies in one of the two following ways.

As a string:

$ lux -c "name=value; name2=value2" "https://www.bilibili.com/video/av20203945"

As a text file:

$ lux -c cookies.txt "https://www.bilibili.com/video/av20203945"

Proxy

You can set the HTTP/SOCKS5 proxy using environment variables:

$ HTTP_PROXY="http://127.0.0.1:1087/" lux -i "https://www.youtube.com/watch?v=Gnbch2osEeo"

$ HTTP_PROXY="socks5://127.0.0.1:1080/" lux -i "https://www.youtube.com/watch?v=Gnbch2osEeo"

Multi-Thread

Use --multi-thread or -m multiple threads to download single video.

Use --thread or -n option to set the number of download threads(default is 10).

Note: If the video has multi fragment, the number of actual download threads will increase.

For example:

If -n is set to 10, and the video has 2 fragments, then 20 threads will actually be used.

If the video has 20 fragments, only 10 fragments are downloaded in the same time, the actual threads count is 100.

Special Tips: Use too many threads in mgtv download will cause HTTP 403 error, we recommend setting the number of threads to 1.
