Use lux -f stream "URL" to download a specific stream listed in the output of -i option.
If Lux is provided the URL of a specific resource, then it will be downloaded directly:
$ lux "https://img9.bcyimg.com/drawer/15294/post/1799t/1f5a87801a0711e898b12b640777720f.jpg" lux doesn't support this URL right now, but it will try to download it directly Site: Universal Title: 1f5a87801a0711e898b12b640777720f Type: image/jpeg Stream: [default] ------------------- Size: 1.00 MiB (1051042 Bytes) # download with: lux -f default "URL" 1.00 MiB / 1.00 MiB [===================================] 100.00% 1.21 MiB/s 0s
The -p option downloads an entire playlist instead of a single video.

-start
Playlist video to start at (default 1)
-end
Playlist video to end at
-items
Playlist video items to download. Separated by commas like: 1,5,6,8-10
For bilibili playlists only:
-eto

You can also download multiple URLs at once:
$ lux -i "https://www.bilibili.com/video/av21877586" "https://www.bilibili.com/video/av21990740" Site: 哔哩哔哩 bilibili.com Title: 【莓机会了】甜到虐哭的13集单集MAD「我现在什么都不想干,更不想看14集」 Type: video Streams: # All available quality [default] ------------------- Quality: 高清 1080P Size: 51.88 MiB (54403767 Bytes) # download with: lux -f default "URL" Site: 哔哩哔哩 bilibili.com Title: 【莓救了】甜到虐哭！！！国家队单集MAD-当熟悉的bgm响起，眼泪从脸颊滑下 Type: video Streams: # All available quality [default] ------------------- Quality: 高清 1080P Size: 77.63 MiB (81404093 Bytes) # download with: lux -f default "URL"
These URLs will be downloaded one by one.
You can also use the -F option to read URLs from file:
$ lux -F ~/Desktop/u.txt Site: 微博 weibo.com Title: 在Google，我们设计什么？ via@阑夕 Type: video Stream: [default] ------------------- Size: 19.19 MiB (20118196 Bytes) # download with: lux -f default "URL" 19.19 MiB / 19.19 MiB [=================================] 100.00% 9.69 MiB/s 1s ......
You can use the -start, -end or -items option to specify the download range of the list:
-start
File line to start at (default 1)
-end
File line to end at
-items
File lines to download. Separated by commas like: 1,5,6,8-10
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.
lux will auto retry when the download failed, you can specify the retry times by -retry option (default is 100).
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"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"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
-nis 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.
You can just use av or ep number to download bilibili's video:
$ lux -i ep198381 av21877586 Site: 哔哩哔哩 bilibili.com Title: 狐妖小红娘：第79话 南国公主的吃货本色 Type: video Streams: # All available quality [default] ------------------- Quality: 高清 1080P Size: 485.23 MiB (508798478 Bytes) # download with: lux -f default "URL" Site: 哔哩哔哩 bilibili.com Title: 【莓机会了】甜到虐哭的13集单集MAD「我现在什么都不想干,更不想看14集」 Type: video Streams: # All available quality [default] ------------------- Quality: 高清 1080P Size: 51.88 MiB (54403767 Bytes) # download with: lux -f default "URL"
