+% YOUTUBE-DL(1)
+
+# NAME
+youtube-dl
+
+# SYNOPSIS
+**youtube-dl** [OPTIONS] URL [URL...]
+
+# 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.x (x being at least 6), and it is not platform specific. It should work in
+your Unix box, in Windows or in Mac OS X. It is released to the public domain,
+which means you can modify it, redistribute it or use it however you like.
+

+## Post-processing Options:
+    -x, --extract-audio      convert video files to audio-only files (requires
+                             ffmpeg or avconv and ffprobe or avprobe)
+    --audio-format FORMAT    "best", "aac", "vorbis", "mp3", "m4a", or "wav";

+    --audio-quality QUALITY  ffmpeg/avconv audio quality specification, insert a
+                             value between 0 (better) and 9 (worse) for VBR or a
+                             specific bitrate like 128K (default 5)
+    -k, --keep-video         keeps the video file on disk after the post-
+                             processing; the video is erased by default
+
+# 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 `~/.local/config/youtube-dl.conf`.
+
+# OUTPUT TEMPLATE
+
+The `-o` option allows users to indicate a template for the output file names. The basic usage is not to set any template arguments when downloading a single file, like in `youtube-dl -o funny_video.flv "http://some/video"`. However, it may contain special sequences that will be replaced when downloading each video. The special sequences have the format `%(NAME)s`. To clarify, that is a percent symbol followed by a name in parenthesis, followed by a lowercase S. Allowed names are:
+
+ - `id`: The sequence will be replaced by the video identifier.
+ - `url`: The sequence will be replaced by the video URL.
+ - `uploader`: The sequence will be replaced by the nickname of the person who uploaded the video.
+ - `upload_date`: The sequence will be replaced by the upload date in YYYYMMDD format.
+ - `title`: The sequence will be replaced by the video title.
+ - `ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
+ - `epoch`: The sequence will be replaced by the Unix epoch when creating the file.
+ - `autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
+
+The current default template is `%(id)s.%(ext)s`, but that will be switchted to `%(title)s-%(id)s.%(ext)s` (which can be requested with `-t` at the moment).
+
+In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the `--restrict-filenames` flag to get a shorter title:
+
+    $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc
+    youtube-dl test video ''_ä↭𝕐.mp4    # All kinds of weird characters
+    $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc --restrict-filenames
+    youtube-dl_test_video_.mp4          # A simple file name
+
+# FAQ
+
+### Can you please put the -b option back?
+
+Most people asking this question are not aware that youtube-dl now defaults to downloading the highest available quality as reported by YouTube, which will be 1080p or 720p in some cases, so you no longer need the -b option. For some specific videos, maybe YouTube does not report them to be available in a specific high quality format you''re interested in. In that case, simply request it with the -f option and youtube-dl will try to download it.
+
+### I get HTTP error 402 when trying to download a video. What's this?
+
+Apparently YouTube requires you to pass a CAPTCHA test if you download too much. We''re [considering to provide a way to let you solve the CAPTCHA](https://github.com/rg3/youtube-dl/issues/154), but at the moment, your best course of action is pointing a webbrowser to the youtube URL, solving the CAPTCHA, and restart youtube-dl.
+
+### I have downloaded a video but how can I play it?
+
+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
+
+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.
+
+### ERROR: no fmt_url_map or conn information found in video info
+
+youtube has switched to a new video info format in July 2011 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
+
+### ERROR: unable to download video ###
+
+youtube requires an additional signature since September 2012 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
+
+### SyntaxError: Non-ASCII character ###
+
+The error
+
+    File "youtube-dl", line 2
+    SyntaxError: Non-ASCII character '\x93' ...
+
+means you're using an outdated version of Python. Please update to Python 2.6 or 2.7.
+
+To run youtube-dl under Python 2.5, you'll have to manually check it out like this:
+
+	git clone git://github.com/rg3/youtube-dl.git
+	cd youtube-dl
+	python -m youtube_dl --help
+
+Please note that Python 2.5 is not supported anymore.
+
+### What is this binary file? Where has the code gone?
+
+Since June 2012 (#342) youtube-dl is packed as an executable zipfile, simply unzip it (might need renaming to `youtube-dl.zip` first on some systems) or clone the git repository, as laid out above. If you modify the code, you can run it by executing the `__main__.py` file. To recompile the executable, run `make youtube-dl`.
+
+### The exe throws a *Runtime error from Visual C++*
+
+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).

+
+# BUGS
+
+Bugs and suggestions should be reported at: <https://github.com/rg3/youtube-dl/issues>
+
+Please include:
+
+* Your exact command line, like `youtube-dl -t "http://www.youtube.com/watch?v=uHlDtZ6Oc3s&feature=channel_video_title"`. A common mistake is not to escape the `&`. Putting URLs in quotes should solve this problem.
+* The output of `youtube-dl --version`
+* The output of `python --version`
+* The name and version of your Operating System ("Ubuntu 11.04 x64" or "Windows 7 x64" is usually enough).

+.SH CONFIGURATION
+.PP
+You can configure youtube-dl by placing default arguments (such as
+\f[C]--extract-audio\ --no-mtime\f[] to always extract the audio and not
+copy the mtime) into \f[C]/etc/youtube-dl.conf\f[] and/or
+\f[C]~/.local/config/youtube-dl.conf\f[].
+.SH OUTPUT TEMPLATE
+.PP
+The \f[C]-o\f[] option allows users to indicate a template for the
+output file names.
+The basic usage is not to set any template arguments when downloading a
+single file, like in
+\f[C]youtube-dl\ -o\ funny_video.flv\ "http://some/video"\f[].
+However, it may contain special sequences that will be replaced when
+downloading each video.
+The special sequences have the format \f[C]%(NAME)s\f[].
+To clarify, that is a percent symbol followed by a name in parenthesis,
+followed by a lowercase S.
+Allowed names are:
+.IP \[bu] 2
+\f[C]id\f[]: The sequence will be replaced by the video identifier.
+.IP \[bu] 2
+\f[C]url\f[]: The sequence will be replaced by the video URL.
+.IP \[bu] 2
+\f[C]uploader\f[]: The sequence will be replaced by the nickname of the
+person who uploaded the video.
+.IP \[bu] 2
+\f[C]upload_date\f[]: The sequence will be replaced by the upload date
+in YYYYMMDD format.
+.IP \[bu] 2
+\f[C]title\f[]: The sequence will be replaced by the video title.
+.IP \[bu] 2
+\f[C]ext\f[]: The sequence will be replaced by the appropriate extension
+(like flv or mp4).
+.IP \[bu] 2
+\f[C]epoch\f[]: The sequence will be replaced by the Unix epoch when
+creating the file.
+.IP \[bu] 2
+\f[C]autonumber\f[]: The sequence will be replaced by a five-digit
+number that will be increased with each download, starting at zero.
+.PP
+The current default template is \f[C]%(id)s.%(ext)s\f[], but that will
+be switchted to \f[C]%(title)s-%(id)s.%(ext)s\f[] (which can be
+requested with \f[C]-t\f[] at the moment).
+.PP
+In some cases, you don\[aq]t want special characters such as 中, spaces,

+system or the filename through an 8bit-unsafe channel.
+In these cases, add the \f[C]--restrict-filenames\f[] flag to get a

+.SH FAQ
+.SS Can you please put the -b option back?
+.PP
+Most people asking this question are not aware that youtube-dl now
+defaults to downloading the highest available quality as reported by
+YouTube, which will be 1080p or 720p in some cases, so you no longer
+need the -b option.
+For some specific videos, maybe YouTube does not report them to be
+available in a specific high quality format you\[aq]\[aq]re interested
+in.
+In that case, simply request it with the -f option and youtube-dl will
+try to download it.
+.SS I get HTTP error 402 when trying to download a video. What\[aq]s
+this?
+.PP
+Apparently YouTube requires you to pass a CAPTCHA test if you download
+too much.
+We\[aq]\[aq]re considering to provide a way to let you solve the
+CAPTCHA (https://github.com/rg3/youtube-dl/issues/154), but at the
+moment, your best course of action is pointing a webbrowser to the
+youtube URL, solving the CAPTCHA, and restart youtube-dl.
+.SS I have downloaded a video but how can I play it?
+.PP
+Once the video is fully downloaded, use any video player, such as
+vlc (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).
+.SS The links provided by youtube-dl -g are not working anymore
+.PP
+The URLs youtube-dl outputs require the downloader to have the correct
+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.
+.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
+not supported by old versions of youtube-dl.
+You can update youtube-dl with \f[C]sudo\ youtube-dl\ --update\f[].
+.SS ERROR: unable to download video
+.PP
+youtube requires an additional signature since September 2012 which is
+not supported by old versions of youtube-dl.
+You can update youtube-dl with \f[C]sudo\ youtube-dl\ --update\f[].
+.SS SyntaxError: Non-ASCII character
+.PP
+The error
+.IP
+.nf
+\f[C]
+File\ "youtube-dl",\ line\ 2
+SyntaxError:\ Non-ASCII\ character\ \[aq]\\x93\[aq]\ ...
+\f[]
+.fi
+.PP
+means you\[aq]re using an outdated version of Python.
+Please update to Python 2.6 or 2.7.
+.PP
+To run youtube-dl under Python 2.5, you\[aq]ll have to manually check it
+out like this:
+.IP
+.nf
+\f[C]
+git\ clone\ git://github.com/rg3/youtube-dl.git
+cd\ youtube-dl
+python\ -m\ youtube_dl\ --help
+\f[]
+.fi
+.PP
+Please note that Python 2.5 is not supported anymore.
+.SS What is this binary file? Where has the code gone?
+.PP
+Since June 2012 (#342) youtube-dl is packed as an executable zipfile,
+simply unzip it (might need renaming to \f[C]youtube-dl.zip\f[] first on
+some systems) or clone the git repository, as laid out above.
+If you modify the code, you can run it by executing the
+\f[C]__main__.py\f[] file.
+To recompile the executable, run \f[C]make\ youtube-dl\f[].
+.SS The exe throws a \f[I]Runtime error from Visual C++\f[]
+.PP
+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).

+class FileDownloader(object):
+	"""File Downloader class.
+
+	File downloader objects are the ones responsible of downloading the
+	actual video file and writing it to disk if the user has requested
+	it, among some other tasks. In most cases there should be one per
+	program. As, given a video URL, the downloader doesn't know how to
+	extract all the needed information, task that InfoExtractors do, it
+	has to pass the URL to one of them.
+
+	For this, file downloader objects have a method that allows
+	InfoExtractors to be registered in a given order. When it is passed
+	a URL, the file downloader handles it to the first InfoExtractor it
+	finds that reports being able to handle it. The InfoExtractor extracts
+	all the information about the video or videos the URL refers to, and
+	asks the FileDownloader to process the video information, possibly
+	downloading the video.
+
+	File downloaders accept a lot of parameters. In order not to saturate
+	the object constructor with arguments, it receives a dictionary of
+	options instead. These options are available through the params
+	attribute for the InfoExtractors to use. The FileDownloader also
+	registers itself as the downloader in charge for the InfoExtractors
+	that are added to it, so this is a "mutual registration".
+
+	Available options:
+
+	username:          Username for authentication purposes.
+	password:          Password for authentication purposes.
+	usenetrc:          Use netrc for authentication instead.
+	quiet:             Do not print messages to stdout.
+	forceurl:          Force printing final URL.
+	forcetitle:        Force printing title.
+	forcethumbnail:    Force printing thumbnail URL.
+	forcedescription:  Force printing description.
+	forcefilename:     Force printing final filename.
+	simulate:          Do not download the video files.
+	format:            Video format code.
+	format_limit:      Highest quality format to try.
+	outtmpl:           Template for output names.
+	restrictfilenames: Do not allow "&" and spaces in file names
+	ignoreerrors:      Do not stop on download errors.
+	ratelimit:         Download speed limit, in bytes/sec.
+	nooverwrites:      Prevent overwriting files.
+	retries:           Number of times to retry for HTTP error 5xx
+	buffersize:        Size of download buffer in bytes.
+	noresizebuffer:    Do not automatically resize the download buffer.
+	continuedl:        Try to continue downloads if possible.
+	noprogress:        Do not print the progress bar.
+	playliststart:     Playlist item to start at.
+	playlistend:       Playlist item to end at.
+	matchtitle:        Download only matching titles.
+	rejecttitle:       Reject downloads for matching titles.
+	logtostderr:       Log messages to stderr instead of stdout.
+	consoletitle:      Display progress in console window's titlebar.
+	nopart:            Do not use temporary .part files.
+	updatetime:        Use the Last-modified header to set output file timestamps.
+	writedescription:  Write the video description to a .description file
+	writeinfojson:     Write the video description to a .info.json file
+	writesubtitles:    Write the video subtitles to a .srt file
+	subtitleslang:     Language of the subtitles to download
