67 | """Information Extractor class. | |
68 | ||
69 | Information extractors are the classes that, given a URL, extract | |
70 | information about the video (or videos) the URL refers to. This | |
71 | information includes the real video URL, the video title, author and | |
72 | others. The information is stored in a dictionary which is then | |
5d380852 | 73 | passed to the YoutubeDL. The YoutubeDL processes this |
d6983cb4 PH |
74 | information possibly downloading the video to the file system, among |
75 | other possible outcomes. | |
76 | ||
cf0649f8 | 77 | The type field determines the type of the result. |

fed5d032 PH |
285 | |
286 | _type "playlist" indicates multiple videos. | |
b82f815f PH |
287 | There must be a key "entries", which is a list, an iterable, or a PagedList |
288 | object, each element of which is a valid dictionary by this specification. | |
fed5d032 | 289 | |
e0b9d78f S |
290 | Additionally, playlists can have "title", "description" and "id" attributes |
291 | with the same semantics as videos (see above). | |
fed5d032 PH |
292 | |
293 | ||
294 | _type "multi_video" indicates that there are multiple videos that | |
295 | form a single show, for examples multiple acts of an opera or TV episode. | |
296 | It must have an entries key like a playlist and contain all the keys | |
297 | required for a video at the same time. | |
298 | ||
299 | ||
300 | _type "url" indicates that the video must be extracted from another | |
301 | location, possibly by a different extractor. Its only required key is: | |
302 | "url" - the next URL to extract. | |
f58766ce PH |
303 | The key "ie_key" can be set to the class name (minus the trailing "IE", |
304 | e.g. "Youtube") if the extractor class is known in advance. | |
305 | Additionally, the dictionary may have any properties of the resolved entity | |
306 | known in advance, for example "title" if the title of the referred video is | |
fed5d032 PH |
307 | known ahead of time. |
308 | ||
309 | ||
310 | _type "url_transparent" entities have the same specification as "url", but | |
311 | indicate that the given additional information is more precise than the one | |
312 | associated with the resolved URL. | |
313 | This is useful when a site employs a video service that hosts the video and | |
314 | its technical metadata, but that video service does not embed a useful | |
315 | title, description etc. | |

318 | Subclasses of this one should re-define the _real_initialize() and |
