64 | """Information Extractor class. | |
65 | ||
66 | Information extractors are the classes that, given a URL, extract | |
67 | information about the video (or videos) the URL refers to. This | |
68 | information includes the real video URL, the video title, author and | |
69 | others. The information is stored in a dictionary which is then | |
5d380852 | 70 | passed to the YoutubeDL. The YoutubeDL processes this |
d6983cb4 PH |
71 | information possibly downloading the video to the file system, among |
72 | other possible outcomes. | |
73 | ||
cf0649f8 | 74 | The type field determines the type of the result. |
fed5d032 PH |
75 | By far the most common value (and the default if _type is missing) is |
76 | "video", which indicates a single video. | |
77 | ||
78 | For a video, the dictionaries must include the following fields: | |

263 | |
264 | _type "playlist" indicates multiple videos. | |
b82f815f PH |
265 | There must be a key "entries", which is a list, an iterable, or a PagedList |
266 | object, each element of which is a valid dictionary by this specification. | |
fed5d032 | 267 | |
e0b9d78f S |
268 | Additionally, playlists can have "title", "description" and "id" attributes |
269 | with the same semantics as videos (see above). | |
fed5d032 PH |
270 | |
271 | ||
272 | _type "multi_video" indicates that there are multiple videos that | |
273 | form a single show, for examples multiple acts of an opera or TV episode. | |
274 | It must have an entries key like a playlist and contain all the keys | |
275 | required for a video at the same time. | |
276 | ||
277 | ||
278 | _type "url" indicates that the video must be extracted from another | |
279 | location, possibly by a different extractor. Its only required key is: | |
280 | "url" - the next URL to extract. | |
f58766ce PH |
281 | The key "ie_key" can be set to the class name (minus the trailing "IE", |
282 | e.g. "Youtube") if the extractor class is known in advance. | |
283 | Additionally, the dictionary may have any properties of the resolved entity | |
284 | known in advance, for example "title" if the title of the referred video is | |
fed5d032 PH |
285 | known ahead of time. |
286 | ||
287 | ||
288 | _type "url_transparent" entities have the same specification as "url", but | |
289 | indicate that the given additional information is more precise than the one | |
290 | associated with the resolved URL. | |
291 | This is useful when a site employs a video service that hosts the video and | |
292 | its technical metadata, but that video service does not embed a useful | |
293 | title, description etc. | |

299 | ||
