95 | """Information Extractor class. |
96 | ||
97 | Information extractors are the classes that, given a URL, extract | |
98 | information about the video (or videos) the URL refers to. This | |
99 | information includes the real video URL, the video title, author and | |
100 | others. The information is stored in a dictionary which is then | |
5d380852 | 101 | passed to the YoutubeDL. The YoutubeDL processes this |
d6983cb4 PH |
102 | information possibly downloading the video to the file system, among |
103 | other possible outcomes. | |
104 | ||
cf0649f8 | 105 | The type field determines the type of the result. |
fed5d032 PH |
106 | By far the most common value (and the default if _type is missing) is |

113 | no title as opposed to "None" which signifies that the | |
114 | extractor failed to obtain a title | |

364 | must return a dict which will be added to the info_dict. | |

425 | _type "playlist" indicates multiple videos. | |
b82f815f PH |
426 | There must be a key "entries", which is a list, an iterable, or a PagedList |
427 | object, each element of which is a valid dictionary by this specification. | |
fed5d032 | 428 | |
962ffcf8 | 429 | Additionally, playlists can have "id", "title", and any other relevant |
b60419c5 | 430 | attributes with the same semantics as videos (see above). |
fed5d032 | 431 | |
f0d785d3 | 432 | It can also have the following optional fields: |
433 | ||
434 | playlist_count: The total number of videos in a playlist. If not given, | |
435 | YoutubeDL tries to calculate it from "entries" | |
436 | ||
fed5d032 PH |
437 | |
438 | _type "multi_video" indicates that there are multiple videos that | |
439 | form a single show, for examples multiple acts of an opera or TV episode. | |
440 | It must have an entries key like a playlist and contain all the keys | |
441 | required for a video at the same time. | |
442 | ||
443 | ||
444 | _type "url" indicates that the video must be extracted from another | |
445 | location, possibly by a different extractor. Its only required key is: | |
446 | "url" - the next URL to extract. | |
f58766ce PH |
447 | The key "ie_key" can be set to the class name (minus the trailing "IE", |
448 | e.g. "Youtube") if the extractor class is known in advance. | |
449 | Additionally, the dictionary may have any properties of the resolved entity | |
450 | known in advance, for example "title" if the title of the referred video is | |
fed5d032 PH |
451 | known ahead of time. |
452 | ||
453 | ||
454 | _type "url_transparent" entities have the same specification as "url", but | |
455 | indicate that the given additional information is more precise than the one | |
456 | associated with the resolved URL. | |
457 | This is useful when a site employs a video service that hosts the video and | |
458 | its technical metadata, but that video service does not embed a useful | |
459 | title, description etc. | |
460 | ||
461 | ||
8f97a15d | 462 | Subclasses of this should also be added to the list of extractors and |
463 | should define a _VALID_URL regexp and, re-define the _real_extract() and | |
464 | (optionally) _real_initialize() methods. | |
d6983cb4 | 465 | |
e6f21b3d | 466 | Subclasses may also override suitable() if necessary, but ensure the function |
467 | signature is preserved and that this function imports everything it needs | |
52efa4b3 | 468 | (except other extractors), so that lazy_extractors works correctly. |
469 | ||
8f97a15d | 470 | Subclasses can define a list of _EMBED_REGEX, which will be searched for in |
471 | the HTML of Generic webpages. It may also override _extract_embed_urls | |
472 | or _extract_from_webpage as necessary. While these are normally classmethods, | |
473 | _extract_from_webpage is allowed to be an instance method. | |
474 | ||
475 | _extract_from_webpage may raise self.StopExtraction() to stop further | |
476 | processing of the webpage and obtain exclusive rights to it. This is useful | |
62b58c09 L |
477 | when the extractor cannot reliably be matched using just the URL, |
478 | e.g. invidious/peertube instances | |
8f97a15d | 479 | |
480 | Embed-only extractors can be defined by setting _VALID_URL = False. | |
481 | ||
52efa4b3 | 482 | To support username + password (or netrc) login, the extractor must define a |
483 | _NETRC_MACHINE and re-define _perform_login(username, password) and | |
484 | (optionally) _initialize_pre_login() methods. The _perform_login method will | |
485 | be called between _initialize_pre_login and _real_initialize if credentials | |
486 | are passed by the user. In cases where it is necessary to have the login | |
487 | process as part of the extraction rather than initialization, _perform_login | |
488 | can be left undefined. | |
e6f21b3d | 489 | |

4248dad9 S |
494 | |
495 | _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted | |
496 | countries for this extractor. One of these countries will be used by | |
497 | geo restriction bypass mechanism right away in order to bypass | |
504f20dd | 498 | geo restriction, of course, if the mechanism is not disabled. |
773f291d | 499 | |

500 | _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted |
501 | IP blocks in CIDR notation for this extractor. One of these IP blocks | |
