## Video Format Options:
-f, --format FORMAT video format code, specify the order of
- preference using slashes: -f 22/17/18 . -f
- mp4 , -f m4a and -f flv are also
- supported. You can also use the special
- names "best", "bestvideo", "bestaudio",
- "worst", "worstvideo" and "worstaudio". By
- default, youtube-dl will pick the best
- quality. Use commas to download multiple
- audio formats, such as -f
+ preference using slashes, as in -f 22/17/18
+ . Instead of format codes, you can select
+ by extension for the extensions aac, m4a,
+ mp3, mp4, ogg, wav, webm. You can also use
+ the special names "best", "bestvideo",
+ "bestaudio", "worst". By default, youtube-
+ dl will pick the best quality. Use commas
+ to download multiple audio formats, such as
+ -f
136/137/mp4/bestvideo,140/m4a/bestaudio.
You can merge the video and audio of two
formats into a single file using -f <video-
# 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
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 maches **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, simply call youtube-dl. 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.
+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.
