-.SS The links provided by youtube\-dl \-g are not working anymore
+.SS I extracted a video URL with \-g, but it does not play on another
+machine / in my webbrowser.
.PP
-The URLs youtube\-dl outputs require the downloader to have the correct
-cookies.
+It depends a lot on the service.
+In many cases, requests for the video (to download/play it) must come
+from the same IP address and with the same cookies.
Use the \f[C]\-\-cookies\f[] option to write the required cookies into a
file, and advise your downloader to read cookies from that file.
Some sites also require a common user agent to be used, use
\f[C]\-\-dump\-user\-agent\f[] to see the one in use by youtube\-dl.
+.PP
+It may be beneficial to use IPv6; in some cases, the restrictions are
+only applied to IPv4.
+Some services (sometimes only for a subset of videos) do not restrict
+the video URL by IP address, cookie, or user\-agent, but these are the
+exception rather than the rule.
+.PP
+Please bear in mind that some URL protocols are \f[B]not\f[] supported
+by browsers out of the box, including RTMP.
+If you are using \-g, your own downloader must support these as well.
+.PP
+If you want to play the video on a machine that is not running
+youtube\-dl, you can relay the video content from the machine that runs
+youtube\-dl.
+You can use \f[C]\-o\ \-\f[] to let youtube\-dl stream a video to
+stdout, or simply allow the player to download the files written by
+youtube\-dl in turn.
.SS ERROR: no fmt_url_map or conn information found in video info
.PP
youtube has switched to a new video info format in July 2011 which is
To run the exe you need to install first the Microsoft Visual C++ 2008
Redistributable
Package (http://www.microsoft.com/en-us/download/details.aspx?id=29).
+.SS On Windows, how should I set up ffmpeg and youtube\-dl? Where should
+I put the exe files?
+.PP
+If you put youtube\-dl and ffmpeg in the same directory that you\[aq]re
+running the command from, it will work, but that\[aq]s rather
+cumbersome.
+.PP
+To make a different directory work \- either for ffmpeg, or for
+youtube\-dl, or for both \- simply create the directory (say,
+\f[C]C:\\bin\f[], or \f[C]C:\\Users\\<User\ name>\\bin\f[]), put all the
+executables directly in there, and then set your PATH environment
+variable (https://www.java.com/en/download/help/path.xml) to include
+that directory.
+.PP
+From then on, after restarting your shell, you will be able to access
+both youtube\-dl and ffmpeg (and youtube\-dl will be able to find
+ffmpeg) by simply typing \f[C]youtube\-dl\f[] or \f[C]ffmpeg\f[], no
+matter what directory you\[aq]re in.
+.SS How can I detect whether a given URL is supported by youtube\-dl?
+.PP
+For one, have a look at the list of supported
+sites (docs/supportedsites).
+Note that it can sometimes happen that the site changes its URL scheme
+(say, from http://example.com/v/1234567 to http://example.com/v/1234567
+) and youtube\-dl reports an URL of a service in that list as
+unsupported.
+In that case, simply report a bug.
+.PP
+It is \f[I]not\f[] possible to detect whether a URL is supported or not.
+That\[aq]s because youtube\-dl contains a generic extractor which
+matches \f[B]all\f[] URLs.
+You may be tempted to disable, exclude, or remove the generic extractor,
+but the generic extractor not only allows users to extract videos from
+lots of websites that embed a video from another service, but may also
+be used to extract video from a service that it\[aq]s hosting itself.
+Therefore, we neither recommend nor support disabling, excluding, or
+removing the generic extractor.
+.PP
+If you want to find out whether a given URL is supported, simply call
+youtube\-dl with it.
+If you get no videos back, chances are the URL is either not referring
+to a video or unsupported.
+You can find out which by examining the output (if you run youtube\-dl
+on the console) or catching an \f[C]UnsupportedError\f[] exception if
+you run it from a Python program.
