The key +mechanism for achieving this is so called _format selection_ based on +which you can explicitly specify desired format, select formats based on +some criterion or criteria, setup precedence and much more. + +The general syntax for format selection is --format FORMAT or shorter +-f FORMAT where FORMAT is a _selector expression_, i.e. an expression +that describes format or formats you would like to download. + +The simplest case is requesting a specific format, for example with +-f 22 you can download the format with format code equal to 22. You can +get the list of available format codes for particular video using +--list-formats or -F. Note that these format codes are extractor +specific. + +You can also use a file extension (currently 3gp, aac, flv, m4a, mp3, +mp4, ogg, wav, webm are supported) to download best quality format of +particular file extension served as a single file, e.g. -f webm will +download best quality format with webm extension served as a single +file. + +You can also use special names to select particular edge case format: - +best: Select best quality format represented by single file with video +and audio - worst: Select worst quality format represented by single +file with video and audio - bestvideo: Select best quality video only +format (e.g. DASH video), may not be available - worstvideo: Select +worst quality video only format, may not be available - bestaudio: +Select best quality audio only format, may not be available - +worstaudio: Select worst quality audio only format, may not be available + +For example, to download worst quality video only format you can use +-f worstvideo. + +If you want to download multiple videos and they don't have the same +formats available, you can specify the order of preference using +slashes. Note that slash is left-associative, i.e. formats on the left +hand side are preferred, for example -f 22/17/18 will download format 22 +if it's available, otherwise it will download format 17 if it's +available, otherwise it will download format 18 if it's available, +otherwise it will complain that no suitable formats are available for +download. + +If you want to download several formats of the same video use comma as a +separator, e.g. -f 22,17,18 will download all these three formats, of +course if they are available. Or more sophisticated example combined +with precedence feature -f 136/137/mp4/bestvideo,140/m4a/bestaudio. + +You can also filter the video formats by putting a condition in +brackets, as in -f "best[height=720]" (or -f "[filesize>10M]"). + +The following numeric meta fields can be used with comparisons <, <=, >, +>=, = (equals), != (not equals): - filesize: The number of bytes, if +known in advance - width: Width of the video, if known - height: Height +of the video, if known - tbr: Average bitrate of audio and video in +KBit/s - abr: Average audio bitrate in KBit/s - vbr: Average video +bitrate in KBit/s - asr: Audio sampling rate in Hertz - fps: Frame rate + +Also filtering work for comparisons = (equals), != (not equals), ^= +(begins with), $= (ends with), *= (contains) and following string meta +fields: - ext: File extension - acodec: Name of the audio codec in use - +vcodec: Name of the video codec in use - container: Name of the +container format - protocol: The protocol that will be used for the +actual download, lower-case. http, https, rtsp, rtmp, rtmpe, m3u8, or +m3u8_native + +Note that none of the aforementioned meta fields are guaranteed to be +present since this solely depends on the metadata obtained by particular +extractor, i.e. the metadata offered by video hoster. + +Formats for which the value is not known are excluded unless you put a +question mark (?) after the operator. You can combine format filters, so +-f "[height <=? 720][tbr>500]" selects up to 720p videos (or videos +where the height is not known) with a bitrate of at least 500 KBit/s. + +You can merge the video and audio of two formats into a single file +using -f + (requires ffmpeg or avconv +installed), for example -f bestvideo+bestaudio will download best video +only format, best audio only format and mux them together with +ffmpeg/avconv. + +Format selectors can also be grouped using parentheses, for example if +you want to download the best mp4 and webm formats with a height lower +than 480 you can use -f '(mp4,webm)[height<480]'. + +Since the end of April 2015 and version 2015.04.26 youtube-dl uses +-f bestvideo+bestaudio/best as default format selection (see #5447, +#5456). If ffmpeg or avconv are installed this results in downloading +bestvideo and bestaudio separately and muxing them together into a +single file giving the best overall quality available. Otherwise it +falls back to best and results in downloading the best available quality +served as a single file. best is also needed for videos that don't come +from YouTube because they don't provide the audio and video in two +different files. If you want to only download some DASH formats (for +example if you are not interested in getting videos with a resolution +higher than 1080p), you can add +-f bestvideo[height<=?1080]+bestaudio/best to your configuration file. +Note that if you use youtube-dl to stream to stdout (and most likely to +pipe it to your media player then), i.e. you explicitly specify output +template as -o -, youtube-dl still uses -f best format selection in +order to start content delivery immediately to your player and not to +wait until bestvideo and bestaudio are downloaded and muxed. + +If you want to preserve the old format selection behavior (prior to +youtube-dl 2015.04.26), i.e. you want to download the best available +quality media served as a single file, you should explicitly specify +your choice with -f best.

HTTP Error 400: Bad Request +when using --cookies is a good sign of invalid newline format. + +Passing cookies to youtube-dl is a good way to workaround login when a +particular extractor does not implement it explicitly. Another use case +is working around CAPTCHA some websites require you to solve in +particular cases in order to get access (e.g. YouTube, CloudFlare). + +Can you add support for this anime video site, or site which shows current movies for free? + +As a matter of policy (as well as legality), youtube-dl does not include +support for services that specialize in infringing copyright. As a rule +of thumb, if you cannot easily find a video that the service is quite +obviously allowed to distribute (i.e. that has been uploaded by the +creator, the creator's distributor, or is published under a free +license), the service is probably unfit for inclusion to youtube-dl. + +A note on the service that they don't host the infringing content, but +just link to those who do, is evidence that the service should NOT be +included into youtube-dl. The same goes for any DMCA note when the whole +front page of the service is filled with videos they are not allowed to +distribute. A "fair use" note is equally unconvincing if the service +shows copyright-protected videos in full without authorization. + +Support requests for services that DO purchase the rights to distribute +their content are perfectly fine though. If in doubt, you can simply +include a source that mentions the legitimate purchase of content. + +How can I speed up work on my issue? + +(Also known as: Help, my important issue not being solved!) The +youtube-dl core developer team is quite small. While we do our best to +solve as many issues as possible, sometimes that can take quite a while. +To speed up your issue, here's what you can do: + +First of all, please do report the issue at our issue tracker. That +allows us to coordinate all efforts by users and developers, and serves +as a unified point. Unfortunately, the youtube-dl project has grown too +large to use personal email as an effective communication channel. + +Please read the bug reporting instructions below. A lot of bugs lack all +the necessary information. If you can, offer proxy, VPN, or shell access +to the youtube-dl developers. If you are able to, test the issue from +multiple computers in multiple countries to exclude local censorship or +misconfiguration issues. + +If nobody is interested in solving your issue, you are welcome to take +matters into your own hands and submit a pull request (or coerce/pay +somebody else to do so). + +Feel free to bump the issue from time to time by writing a small comment +("Issue is still present in youtube-dl version ...from France, but fixed +from Belgium"), but please not more than once a month. Please do not +declare your issue as important or urgent. + +How can I detect whether a given URL is supported by youtube-dl? + +For one, have a look at the list of supported sites. Note that it can +sometimes happen that the site changes its URL scheme (say, from +http://example.com/video/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 +or get them from their distribution. + +To run youtube-dl as a developer, you don't need to build anything +either.

While in most +cases we eventually get the required information after asking back +multiple times, this poses an unnecessary drain on our resources. Many +contributors, including myself, are also not native speakers, so we may +misread some parts. + +So please elaborate on what feature you are requesting, or what bug you +want to be fixed. Make sure that it's obvious + +- What the problem is +- How it could be fixed +- How your proposed solution would look like + +If your report is shorter than two lines, it is almost certainly missing +some of these, which makes it hard for us to respond to it. We're often +too polite to close the issue outright, but the missing info makes +misinterpretation likely. As a committer myself, I often get frustrated +by these issues, since the only possible way for me to move forward on +them is to ask for clarification over and over. + +For bug reports, this means that your report should contain the +_complete_ output of youtube-dl when called with the -v flag. The error +message you get for (most) bugs even says so, but you would not believe +how many of our bug reports do not contain this information. + +If your server has multiple IPs or you suspect censorship, adding +--call-home may be a good idea to get more diagnostics. If the error is +ERROR: Unable to extract ... and you cannot reproduce it from multiple +countries, add --dump-pages (warning: this will yield a rather large +output, redirect it to the file log.txt by adding >log.txt 2>&1 to your +command-line) or upload the .dump files you get when you add +--write-pages somewhere. + +SITE SUPPORT REQUESTS MUST CONTAIN AN EXAMPLE URL. An example URL is a +URL you might want to download, like +http://www.youtube.com/watch?v=BaW_jenozKc. There should be an obvious +video present. Except under very special circumstances, the main page of +a video service (e.g. http://www.youtube.com/) is _not_ an example URL. + +Are you using the latest version? + +Before reporting any issue, type youtube-dl -U. This should report that +you're up-to-date. About 20% of the reports we receive are already +fixed, but people are using outdated versions. This goes for feature +requests as well. + +Is the issue already documented? + +Make sure that someone has not already opened the issue you're trying to +open. Search at the top of the window or browse the GitHub Issues of +this repository. If there is an issue, feel free to write something +along the lines of "This affects me as well, with version 2015.01.01. +Here is some more information on the issue: ...". While some issues may +be old, a new post into them often spurs rapid activity. + +Why are existing options not enough? + +Before requesting a new feature, please have a quick peek at the list of +supported options. Many feature requests are for features that actually +exist already! Please, absolutely do show off your work in the issue +report and detail how the existing similar options do _not_ solve your +problem. + +Is there enough context in your bug report? + +People want to solve problems, and often think they do us a favor by +breaking down their larger problems (e.g. wanting to skip already +downloaded files) to a specific request (e.g. requesting us to look +whether the file exists before downloading the info page). However, what +often happens is that they break down the problem into two steps: One +simple, and one impossible (or extremely complicated one). + +We are then presented with a very complicated request when the original +problem could be solved far easier, e.g. by recording the downloaded +video IDs in a separate file. To avoid this, you must include the +greater context where it is non-obvious. In particular, every feature +request that does not consist of adding support for a new site should +contain a use case scenario that explains in what situation the missing +feature would be useful. + +Does the issue involve one problem, and one problem only? + +Some of our users seem to think there is a limit of issues they can or +should open. There is no limit of issues they can or should open. While +it may seem appealing to be able to dump all your issues into one +ticket, that means that someone who solves one of your issues cannot +mark the issue as closed. Typically, reporting a bunch of issues leads +to the ticket lingering since nobody wants to attack that behemoth, +until someone mercifully splits the issue into multiple ones. + +In particular, every site support request issue should only pertain to +services at one site (generally under a common domain, but always using +the same backend technology). Do not request support for vimeo user +videos, Whitehouse podcasts, and Google Plus pages in the same issue. +Also, make sure that you don't post bug reports alongside feature +requests. As a rule of thumb, a feature request does not include outputs +of youtube-dl that are not immediately related to the feature at hand. +Do not post reports of a network error alongside the request for a new +video service. + +Is anyone going to need the feature? + +Only post features that you (or an incapacitated friend you can +personally talk to) require. Do not post features because they seem like +a good idea. If they are really useful, they will be requested by +someone who requires them. + +Is your question about youtube-dl? + +It may sound strange, but some bug reports we receive are completely +unrelated to youtube-dl and relate to a different or even the reporter's +own application. Please make sure that you are actually using +youtube-dl. If you are using a UI for youtube-dl, report the bug to the +maintainer of the actual application providing the UI. On the other +hand, if your UI for youtube-dl fails in some way you believe is related +to youtube-dl, by all means, go ahead and report the bug. + + + +COPYRIGHT + + +youtube-dl is released into the public domain by the copyright holders. + +This README file was originally written by Daniel Bolton and is likewise +released into the public domain.
