 442         it, among some other tasks. In most cases there should be one per
 443         program. As, given a video URL, the downloader doesn't know how to
 444         extract all the needed information, task that InfoExtractors do, it
 445         has to pass the URL to one of them.
 446
 447         For this, file downloader objects have a method that allows
 448         InfoExtractors to be registered in a given order. When it is passed
 449         a URL, the file downloader handles it to the first InfoExtractor it
 450         finds that reports being able to handle it. The InfoExtractor extracts
 451         all the information about the video or videos the URL refers to, and
 452         asks the FileDownloader to process the video information, possibly
 453         downloading the video.

1083         Information extractors are the classes that, given a URL, extract
1084         information from the video (or videos) the URL refers to. This
1085         information includes the real video URL, the video title and simplified
1086         title, author and others. The information is stored in a dictionary
1087         which is then passed to the FileDownloader. The FileDownloader
1088         processes this information possibly downloading the video to the file
1089         system, among other possible outcomes. The dictionaries must include
1090         the following fields:
1091
1092         id:             Video identifier.
1093         url:            Final video URL.
1094         uploader:       Nickname of the video uploader.
1095         title:          Literal title.
1096         stitle:         Simplified title.
1097         ext:            Video filename extension.
1098         format:         Video format.
1099         player_url:     SWF Player URL (may be None).
1100
1101         The following fields are optional. Their primary purpose is to allow
1102         youtube-dl to serve as the backend for a video search function, such
1103         as the one in youtube2mp3.  They are only used when their respective
1104         forced printing functions are called:
1105
1106         thumbnail:      Full URL to a video thumbnail image.
1107         description:    One-line video description.
1108
1109         Subclasses of this one should re-define the _real_initialize() and
1110         _real_extract() methods and define a _VALID_URL regexp.
1111         Probably, they should also be added to the list of extractors.
