91 | class InfoExtractor: | |
92 | """Information Extractor class. | |
93 | ||
94 | Information extractors are the classes that, given a URL, extract | |
95 | information about the video (or videos) the URL refers to. This | |
96 | information includes the real video URL, the video title, author and | |
97 | others. The information is stored in a dictionary which is then | |
98 | passed to the YoutubeDL. The YoutubeDL processes this | |
99 | information possibly downloading the video to the file system, among | |
100 | other possible outcomes. | |
101 | ||
102 | The type field determines the type of the result. | |
103 | By far the most common value (and the default if _type is missing) is | |
104 | "video", which indicates a single video. | |
105 | ||
106 | For a video, the dictionaries must include the following fields: | |
107 | ||
108 | id: Video identifier. | |
109 | title: Video title, unescaped. Set to an empty string if video has | |
110 | no title as opposed to "None" which signifies that the | |
111 | extractor failed to obtain a title | |
112 | ||
113 | Additionally, it must contain either a formats entry or a url one: | |
114 | ||
115 | formats: A list of dictionaries for each format available, ordered | |
116 | from worst to best quality. | |
117 | ||
118 | Potential fields: | |
119 | * url The mandatory URL representing the media: | |
120 | for plain file media - HTTP URL of this file, | |

123 | for HDS - URL of the F4M manifest, | |
124 | for DASH | |
125 | - HTTP URL to plain file media (in case of | |
126 | unfragmented media) | |
127 | - URL of the MPD manifest or base URL | |
128 | representing the media if MPD manifest | |
129 | is parsed from a string (in case of | |
130 | fragmented media) | |
131 | for MSS - URL of the ISM manifest. | |
132 | * manifest_url | |
133 | The URL of the manifest file in case of | |
134 | fragmented media: | |
135 | for HLS - URL of the M3U8 master playlist, | |

173 | value (if present) will be relative to | |
174 | this URL. | |
175 | * fragments A list of fragments of a fragmented media. | |
176 | Each fragment entry must contain either an url | |
177 | or a path. If an url is present it should be | |
178 | considered by a client. Otherwise both path and | |
179 | fragment_base_url must be present. Here is | |
180 | the list of all potential fields: | |

189 | present and not None, the formats get sorted | |
190 | by this field, regardless of all other values. | |
191 | -1 for default (order by other properties), | |
192 | -2 or smaller for less than default. | |
193 | < -1000 to hide the format (if there is | |

203 | -1 for default (order by other properties), | |
204 | -2 or smaller for less than default. | |
205 | * source_preference Order number for this video source | |
206 | (quality takes higher priority) | |
207 | -1 for default (order by other properties), | |
208 | -2 or smaller for less than default. | |
209 | * http_headers A dictionary of additional HTTP headers | |
210 | to add to the request. | |
211 | * stretched_ratio If given and not 1, indicates that the | |
212 | video's pixels are not square. | |

348 | time-consuming to extract. Note that the fields thus | |
349 | extracted will not be available to output template and | |

351 | currently allowed to be extracted via this method. | |
352 | ||
353 | The following fields should only be used when the video belongs to some logical | |

365 | season: Title of the season the video episode belongs to. | |
366 | season_number: Number of the season the video episode belongs to, as an integer. | |
367 | season_id: Id of the season the video episode belongs to, as a unicode string. | |
368 | episode: Title of the video episode. Unlike mandatory video title field, | |
369 | this field should denote the exact title of the video episode | |
370 | without any kind of decoration. | |
371 | episode_number: Number of the video episode within a season, as an integer. | |
372 | episode_id: Id of the video episode, as a unicode string. | |
373 | ||
374 | The following fields should only be used when the media is a track or a part of | |
375 | a music album: | |
376 | ||
377 | track: Title of the track. | |
378 | track_number: Number of the track within an album or a disc, as an integer. | |
379 | track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii), | |
380 | as a unicode string. | |
381 | artist: Artist(s) of the track. | |
382 | genre: Genre(s) of the track. | |
383 | album: Title of the album the track belongs to. | |

385 | album_artist: List of all artists appeared on the album (e.g. | |
386 | "Ash Borer / Fell Voices" or "Various Artists", useful for splits | |
387 | and compilations). | |
388 | disc_number: Number of the disc or other physical medium the track belongs to, | |
389 | as an integer. | |
390 | release_year: Year (YYYY) when the album was released. | |
391 | composer: Composer of the piece | |
392 | ||
393 | The following fields should only be set for clips that should be cut from the original video: | |
394 | ||
395 | section_start: Start time of the section in seconds | |
396 | section_end: End time of the section in seconds | |
397 | ||
398 | The following fields should only be set for storyboards: | |
399 | rows: Number of rows in each storyboard fragment, as an integer | |
400 | columns: Number of columns in each storyboard fragment, as an integer | |
401 | ||
402 | Unless mentioned otherwise, the fields should be Unicode strings. | |
403 | ||
404 | Unless mentioned otherwise, None is equivalent to absence of information. | |
405 | ||
406 | ||
407 | _type "playlist" indicates multiple videos. | |
408 | There must be a key "entries", which is a list, an iterable, or a PagedList | |
409 | object, each element of which is a valid dictionary by this specification. | |
410 | ||
411 | Additionally, playlists can have "id", "title", and any other relevant | |
412 | attributes with the same semantics as videos (see above). | |
413 | ||
414 | It can also have the following optional fields: | |
415 | ||
416 | playlist_count: The total number of videos in a playlist. If not given, | |
417 | YoutubeDL tries to calculate it from "entries" | |
418 | ||
419 | ||
420 | _type "multi_video" indicates that there are multiple videos that | |
421 | form a single show, for examples multiple acts of an opera or TV episode. | |
422 | It must have an entries key like a playlist and contain all the keys | |
423 | required for a video at the same time. | |
424 | ||
425 | ||
426 | _type "url" indicates that the video must be extracted from another | |
427 | location, possibly by a different extractor. Its only required key is: | |
428 | "url" - the next URL to extract. | |
429 | The key "ie_key" can be set to the class name (minus the trailing "IE", | |
430 | e.g. "Youtube") if the extractor class is known in advance. | |
431 | Additionally, the dictionary may have any properties of the resolved entity | |
432 | known in advance, for example "title" if the title of the referred video is | |
433 | known ahead of time. | |
434 | ||
435 | ||
436 | _type "url_transparent" entities have the same specification as "url", but | |
437 | indicate that the given additional information is more precise than the one | |
438 | associated with the resolved URL. | |
439 | This is useful when a site employs a video service that hosts the video and | |
440 | its technical metadata, but that video service does not embed a useful | |
441 | title, description etc. | |
442 | ||
443 | ||
444 | Subclasses of this should also be added to the list of extractors and | |
445 | should define a _VALID_URL regexp and, re-define the _real_extract() and | |
446 | (optionally) _real_initialize() methods. | |
447 | ||
448 | Subclasses may also override suitable() if necessary, but ensure the function | |
449 | signature is preserved and that this function imports everything it needs | |
450 | (except other extractors), so that lazy_extractors works correctly. | |
451 | ||
452 | Subclasses can define a list of _EMBED_REGEX, which will be searched for in | |
453 | the HTML of Generic webpages. It may also override _extract_embed_urls | |
454 | or _extract_from_webpage as necessary. While these are normally classmethods, | |
455 | _extract_from_webpage is allowed to be an instance method. | |
456 | ||
457 | _extract_from_webpage may raise self.StopExtraction() to stop further | |

466 | (optionally) _initialize_pre_login() methods. The _perform_login method will | |
467 | be called between _initialize_pre_login and _real_initialize if credentials | |

476 | ||
477 | _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted | |
478 | countries for this extractor. One of these countries will be used by | |

482 | _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted | |
483 | IP blocks in CIDR notation for this extractor. One of these IP blocks | |
484 | will be used by geo restriction bypass mechanism similarly | |
