104 | class InfoExtractor: | |
105 | """Information Extractor class. | |
106 | ||
107 | Information extractors are the classes that, given a URL, extract | |
108 | information about the video (or videos) the URL refers to. This | |
109 | information includes the real video URL, the video title, author and | |
110 | others. The information is stored in a dictionary which is then | |
111 | passed to the YoutubeDL. The YoutubeDL processes this | |
112 | information possibly downloading the video to the file system, among | |
113 | other possible outcomes. | |
114 | ||
115 | The type field determines the type of the result. | |
116 | By far the most common value (and the default if _type is missing) is | |
117 | "video", which indicates a single video. | |
118 | ||
119 | For a video, the dictionaries must include the following fields: | |
120 | ||
121 | id: Video identifier. | |
122 | title: Video title, unescaped. Set to an empty string if video has | |
123 | no title as opposed to "None" which signifies that the | |
124 | extractor failed to obtain a title | |
125 | ||
126 | Additionally, it must contain either a formats entry or a url one: | |
127 | ||
128 | formats: A list of dictionaries for each format available, ordered | |

453 | ||
454 | Additionally, playlists can have "id", "title", and any other relevant | |
455 | attributes with the same semantics as videos (see above). | |
456 | ||
457 | It can also have the following optional fields: | |
458 | ||
459 | playlist_count: The total number of videos in a playlist. If not given, | |
460 | YoutubeDL tries to calculate it from "entries" | |
461 | ||
462 | ||
463 | _type "multi_video" indicates that there are multiple videos that | |
464 | form a single show, for examples multiple acts of an opera or TV episode. | |
465 | It must have an entries key like a playlist and contain all the keys | |
466 | required for a video at the same time. | |
467 | ||
468 | ||
469 | _type "url" indicates that the video must be extracted from another | |
470 | location, possibly by a different extractor. Its only required key is: | |
471 | "url" - the next URL to extract. | |
472 | The key "ie_key" can be set to the class name (minus the trailing "IE", | |
473 | e.g. "Youtube") if the extractor class is known in advance. | |
474 | Additionally, the dictionary may have any properties of the resolved entity | |
475 | known in advance, for example "title" if the title of the referred video is | |
476 | known ahead of time. | |
477 | ||
478 | ||
479 | _type "url_transparent" entities have the same specification as "url", but | |
480 | indicate that the given additional information is more precise than the one | |
481 | associated with the resolved URL. | |
482 | This is useful when a site employs a video service that hosts the video and | |
483 | its technical metadata, but that video service does not embed a useful | |
484 | title, description etc. | |
485 | ||
486 | ||
487 | Subclasses of this should also be added to the list of extractors and | |
488 | should define _VALID_URL as a regexp or a Sequence of regexps, and | |
489 | re-define the _real_extract() and (optionally) _real_initialize() methods. | |
490 | ||
491 | Subclasses may also override suitable() if necessary, but ensure the function | |
492 | signature is preserved and that this function imports everything it needs | |
493 | (except other extractors), so that lazy_extractors works correctly. | |
494 | ||
495 | Subclasses can define a list of _EMBED_REGEX, which will be searched for in | |
496 | the HTML of Generic webpages. It may also override _extract_embed_urls | |
497 | or _extract_from_webpage as necessary. While these are normally classmethods, | |
498 | _extract_from_webpage is allowed to be an instance method. | |
499 | ||
500 | _extract_from_webpage may raise self.StopExtraction() to stop further | |
501 | processing of the webpage and obtain exclusive rights to it. This is useful | |
502 | when the extractor cannot reliably be matched using just the URL, | |
503 | e.g. invidious/peertube instances | |
504 | ||
505 | Embed-only extractors can be defined by setting _VALID_URL = False. | |
506 | ||
507 | To support username + password (or netrc) login, the extractor must define a | |
508 | _NETRC_MACHINE and re-define _perform_login(username, password) and | |
509 | (optionally) _initialize_pre_login() methods. The _perform_login method will | |
510 | be called between _initialize_pre_login and _real_initialize if credentials | |
511 | are passed by the user. In cases where it is necessary to have the login | |
512 | process as part of the extraction rather than initialization, _perform_login | |
513 | can be left undefined. | |
514 | ||
515 | _GEO_BYPASS attribute may be set to False in order to disable | |
516 | geo restriction bypass mechanisms for a particular extractor. | |
517 | Though it won't disable explicit geo restriction bypass based on | |
518 | country code provided with geo_bypass_country. | |
519 | ||
520 | _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted | |
521 | countries for this extractor. One of these countries will be used by | |
522 | geo restriction bypass mechanism right away in order to bypass | |
523 | geo restriction, of course, if the mechanism is not disabled. | |
524 | ||
525 | _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted | |
526 | IP blocks in CIDR notation for this extractor. One of these IP blocks | |
527 | will be used by geo restriction bypass mechanism similarly | |
528 | to _GEO_COUNTRIES. | |
529 | ||
530 | The _ENABLED attribute should be set to False for IEs that | |
531 | are disabled by default and must be explicitly enabled. | |
532 | ||
533 | The _WORKING attribute should be set to False for broken IEs | |
534 | in order to warn the users and skip the tests. | |
