# INSTALLATION
# DESCRIPTION
**youtube-dl** is a small command-line program to download videos from
YouTube.com and a few more sites. It requires the Python interpreter, version
-2.6, 2.7, or 3.3+, and it is not platform specific. It should work on
+2.6, 2.7, or 3.2+, and it is not platform specific. It should work on
your Unix box, on Windows or on Mac OS X. It is released to the public domain,
which means you can modify it, redistribute it or use it however you like.

they would handle
--extractor-descriptions Output descriptions of all supported
extractors
- --proxy URL Use the specified HTTP/HTTPS proxy. Pass in
- an empty string (--proxy "") for direct

postprocessors (default)
--prefer-ffmpeg Prefer ffmpeg over avconv for running the
# CONFIGURATION
-You can configure youtube-dl by placing default arguments (such as `--extract-audio --no-mtime` to always extract the audio and not copy the mtime) into `/etc/youtube-dl.conf` and/or `~/.config/youtube-dl/config`. On Windows, the configuration file locations are `%APPDATA%\youtube-dl\config.txt` and `C:\Users\<Yourname>\youtube-dl.conf`.

# OUTPUT TEMPLATE
Once the video is fully downloaded, use any video player, such as [vlc](http://www.videolan.org) or [mplayer](http://www.mplayerhq.hu/).
-### The links provided by youtube-dl -g are not working anymore
+### I extracted a video URL with -g, but it does not play on another machine / in my webbrowser.
+
+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 `--cookies` 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 `--dump-user-agent` to see the one in use by youtube-dl.
+
+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.
+
+Please bear in mind that some URL protocols are **not** supported by browsers out of the box, including RTMP. If you are using -g, your own downloader must support these as well.
-The URLs youtube-dl outputs require the downloader to have the correct cookies. Use the `--cookies` 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 `--dump-user-agent` to see the one in use by youtube-dl.
+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 `-o -` to let youtube-dl stream a video to stdout, or simply allow the player to download the files written by youtube-dl in turn.
### ERROR: no fmt_url_map or conn information found in video info
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).
+### On Windows, how should I set up ffmpeg and youtube-dl? Where should I put the exe files?
+
+If you put youtube-dl and ffmpeg in the same directory that you're running the command from, it will work, but that's rather cumbersome.
+
+To make a different directory work - either for ffmpeg, or for youtube-dl, or for both - simply create the directory (say, `C:\bin`, or `C:\Users\<User name>\bin`), 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.
+
+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 `youtube-dl` or `ffmpeg`, no matter what directory you're in.
+
+### How can I detect whether a given URL is supported by youtube-dl?
+
+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.
+
+It is *not* possible to detect whether a URL is supported or not. That's because youtube-dl contains a generic extractor which matches **all** 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's hosting itself. Therefore, we neither recommend nor support disabling, excluding, or removing the generic extractor.
+
+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 `UnsupportedError` exception if you run it from a Python program.

# DEVELOPER INSTRUCTIONS
Most users do not need to build youtube-dl and can [download the builds](http://rg3.github.io/youtube-dl/download.html) or get them from their distribution.
def _real_extract(self, url):
video_id = self._match_id(url)
+ webpage = self._download_webpage(url, video_id)
# TODO more code goes here, for example ...
- webpage = self._download_webpage(url, video_id)
title = self._html_search_regex(r'<h1>(.*?)</h1>', webpage, 'title')
return {
'id': video_id,
'title': title,
+ 'description': self._og_search_description(webpage),
# TODO more properties (see youtube_dl/extractor/common.py)
}
```
From a Python program, you can embed youtube-dl in a more powerful fashion, like this:
- import youtube_dl
+```python
+import youtube_dl
- ydl_opts = {}
- with youtube_dl.YoutubeDL(ydl_opts) as ydl:
- ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+ydl_opts = {}
+with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+ ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+```
Most likely, you'll want to use various options. For a list of what can be done, have a look at [youtube_dl/YoutubeDL.py](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py#L69). For a start, if you want to intercept youtube-dl's output, set a `logger` object.
+Here's a more complete example of a program that outputs only errors (and a short message after the download is finished), and downloads/converts the video to an mp3 file:
+
+```python
+import youtube_dl
+
+
+class MyLogger(object):
+ def debug(self, msg):
+ pass
+
+ def warning(self, msg):
+ pass
+
+ def error(self, msg):
+ print(msg)
+
+
+def my_hook(d):
+ if d['status'] == 'finished':
+ print('Done downloading, now converting ...')
+
+
+ydl_opts = {
+ 'format': 'bestaudio/best',
+ 'postprocessors': [{
+ 'key': 'FFmpegExtractAudio',
+ 'preferredcodec': 'mp3',
+ 'preferredquality': '192',
+ }],
+ 'logger': MyLogger(),
+ 'progress_hooks': [my_hook],
+}
+with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+ ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+```
