376 | album_artist: List of all artists appeared on the album (e.g. | |
377 | "Ash Borer / Fell Voices" or "Various Artists", useful for splits | |
378 | and compilations). | |
379 | disc_number: Number of the disc or other physical medium the track belongs to, | |
380 | as an integer. | |
381 | release_year: Year (YYYY) when the album was released. | |
8bcd4048 | 382 | composer: Composer of the piece |

388 | |
389 | _type "playlist" indicates multiple videos. | |
b82f815f PH |
390 | There must be a key "entries", which is a list, an iterable, or a PagedList |
391 | object, each element of which is a valid dictionary by this specification. | |
fed5d032 | 392 | |
b60419c5 | 393 | Additionally, playlists can have "id", "title", and any other relevent |
394 | attributes with the same semantics as videos (see above). | |
fed5d032 | 395 | |
f0d785d3 | 396 | It can also have the following optional fields: |
397 | ||
398 | playlist_count: The total number of videos in a playlist. If not given, | |
399 | YoutubeDL tries to calculate it from "entries" | |
400 | ||
fed5d032 PH |
401 | |
402 | _type "multi_video" indicates that there are multiple videos that | |
403 | form a single show, for examples multiple acts of an opera or TV episode. | |
404 | It must have an entries key like a playlist and contain all the keys | |
405 | required for a video at the same time. | |
406 | ||
407 | ||
408 | _type "url" indicates that the video must be extracted from another | |
409 | location, possibly by a different extractor. Its only required key is: | |
410 | "url" - the next URL to extract. | |
f58766ce PH |
411 | The key "ie_key" can be set to the class name (minus the trailing "IE", |
412 | e.g. "Youtube") if the extractor class is known in advance. | |
413 | Additionally, the dictionary may have any properties of the resolved entity | |
414 | known in advance, for example "title" if the title of the referred video is | |
fed5d032 PH |
415 | known ahead of time. |
416 | ||
417 | ||
418 | _type "url_transparent" entities have the same specification as "url", but | |
419 | indicate that the given additional information is more precise than the one | |
420 | associated with the resolved URL. | |
421 | This is useful when a site employs a video service that hosts the video and | |
422 | its technical metadata, but that video service does not embed a useful | |
423 | title, description etc. | |
424 | ||
425 | ||
08d30158 | 426 | Subclasses of this should define a _VALID_URL regexp and, re-define the |
427 | _real_extract() and (optionally) _real_initialize() methods. | |
d6983cb4 PH |
428 | Probably, they should also be added to the list of extractors. |
429 | ||
e6f21b3d | 430 | Subclasses may also override suitable() if necessary, but ensure the function |
431 | signature is preserved and that this function imports everything it needs | |
52efa4b3 | 432 | (except other extractors), so that lazy_extractors works correctly. |
433 | ||
434 | To support username + password (or netrc) login, the extractor must define a | |
435 | _NETRC_MACHINE and re-define _perform_login(username, password) and | |
436 | (optionally) _initialize_pre_login() methods. The _perform_login method will | |
437 | be called between _initialize_pre_login and _real_initialize if credentials | |
438 | are passed by the user. In cases where it is necessary to have the login | |
439 | process as part of the extraction rather than initialization, _perform_login | |
440 | can be left undefined. | |
e6f21b3d | 441 | |
4248dad9 | 442 | _GEO_BYPASS attribute may be set to False in order to disable |
773f291d S |
443 | geo restriction bypass mechanisms for a particular extractor. |
444 | Though it won't disable explicit geo restriction bypass based on | |
504f20dd | 445 | country code provided with geo_bypass_country. |
4248dad9 S |
446 | |
447 | _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted | |
448 | countries for this extractor. One of these countries will be used by | |
449 | geo restriction bypass mechanism right away in order to bypass | |
504f20dd | 450 | geo restriction, of course, if the mechanism is not disabled. |
773f291d | 451 | |
5f95927a S |
452 | _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted |
453 | IP blocks in CIDR notation for this extractor. One of these IP blocks | |
454 | will be used by geo restriction bypass mechanism similarly | |
504f20dd | 455 | to _GEO_COUNTRIES. |
3ccdde8c | 456 | |
e6f21b3d | 457 | The _WORKING attribute should be set to False for broken IEs |
