我通常使用keepvid.com或Firefox下载助手插件来下载YouTube视频。在Linux中可用的wget命令有可能能够下载它们吗?
另外,我有一个VPS服务器。我想在VPS服务器(cPanel)上下载视频。
如果可以的话,应该如何操作呢?
谢谢。
#!/usr/bin/perl
use strict;
use warnings;
## Two arguments
## $1 YouTube URL from the browser
## $2 Prefix to the file name of the video (optional)
#
## Collect the URL from the command line argument
my $url = $ARGV[0] or die "\nError: You need to specify a YouTube URL\n\n";
## Declare the user defined file name prefix
my $prefix = defined($ARGV[1]) ? $ARGV[1] : "";
## Download the HTML code from the YouTube page
my $html = `wget -Ncq -e "convert-links=off" --keep-session-cookies --save-cookies /dev/null --no-check-certificate "$url" -O-` or die "\nThere was a problem downloading the HTML file.\n\n";
## Collect the title of the page to use as the file name
my ($title) = $html =~ m/<title>(.+)<\/title>/si;
$title =~ s/[^\w\d]+/_/g;
$title =~ s/_youtube//ig;
$title =~ s/^_//ig;
$title = lc ($title);
## Collect the URL of the video
my ($download) = $html =~ /"url_encoded_fmt_stream_map"([\s\S]+?)\,/ig;
## Clean up the URL by translating Unicode and removing unwanted strings
$download =~ s/\:\ \"//;
$download =~ s/%3A/:/g;
$download =~ s/%2F/\//g;
$download =~ s/%3F/\?/g;
$download =~ s/%3D/\=/g;
$download =~ s/%252C/%2C/g;
$download =~ s/%26/\&/g;
$download =~ s/sig=/signature=/g;
$download =~ s/\\u0026/\&/g;
$download =~ s/(type=[^&]+)//g;
$download =~ s/(fallback_host=[^&]+)//g;
$download =~ s/(quality=[^&]+)//g;
## Collect the URL and signature since the HTML page randomizes the order
my ($signature) = $download =~ /(signature=[^&]+)/;
my ($youtubeurl) = $download =~ /(http.+)/;
$youtubeurl =~ s/&signature.+$//;
## Combine the URL and signature in order to use in Wget
$download = "$youtubeurl\&$signature";
## A bit more cleanup
$download =~ s/&+/&/g;
$download =~ s/&itag=\d+&signature=/&signature=/g;
## Print the file name of the video collected from the web page title for us to see on the CLI
print "\n Download: $prefix$title.webm\n\n";
## Download the file using Wget and background the Wget process
system("wget -Ncq -e \"convert-links=off\" --load-cookies /dev/null --tries=50 --timeout=45 --no-check-certificate \"$download\" -O $prefix$title.webm &");

这是我使用了一段时间的Perl脚本。虽然我不确定它来自哪里...但它运行得非常好。
