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:

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.
