22 | """YoutubeDL class. | |
23 | ||
24 | YoutubeDL objects are the ones responsible of downloading the | |
25 | actual video file and writing it to disk if the user has requested | |
26 | it, among some other tasks. In most cases there should be one per | |
27 | program. As, given a video URL, the downloader doesn't know how to | |
28 | extract all the needed information, task that InfoExtractors do, it | |
29 | has to pass the URL to one of them. | |
30 | ||
31 | For this, YoutubeDL objects have a method that allows | |
32 | InfoExtractors to be registered in a given order. When it is passed | |
33 | a URL, the YoutubeDL object handles it to the first InfoExtractor it | |
34 | finds that reports being able to handle it. The InfoExtractor extracts | |
35 | all the information about the video or videos the URL refers to, and | |
36 | YoutubeDL process the extracted information, possibly using a File | |
37 | Downloader to download the video. | |
38 | ||
39 | YoutubeDL objects accept a lot of parameters. In order not to saturate | |
40 | the object constructor with arguments, it receives a dictionary of | |
41 | options instead. These options are available through the params | |
42 | attribute for the InfoExtractors to use. The YoutubeDL also | |
43 | registers itself as the downloader in charge for the InfoExtractors | |
44 | that are added to it, so this is a "mutual registration". | |
