123 | class YoutubeDL(object): | |
124 | """YoutubeDL class. | |
125 | ||
126 | YoutubeDL objects are the ones responsible of downloading the | |
127 | actual video file and writing it to disk if the user has requested | |
128 | it, among some other tasks. In most cases there should be one per | |
129 | program. As, given a video URL, the downloader doesn't know how to | |
130 | extract all the needed information, task that InfoExtractors do, it | |
131 | has to pass the URL to one of them. | |
132 | ||
133 | For this, YoutubeDL objects have a method that allows | |
134 | InfoExtractors to be registered in a given order. When it is passed | |
135 | a URL, the YoutubeDL object handles it to the first InfoExtractor it | |
136 | finds that reports being able to handle it. The InfoExtractor extracts | |
137 | all the information about the video or videos the URL refers to, and | |
138 | YoutubeDL process the extracted information, possibly using a File | |
139 | Downloader to download the video. | |
140 | ||
141 | YoutubeDL objects accept a lot of parameters. In order not to saturate | |
142 | the object constructor with arguments, it receives a dictionary of | |
143 | options instead. These options are available through the params | |
144 | attribute for the InfoExtractors to use. The YoutubeDL also | |
145 | registers itself as the downloader in charge for the InfoExtractors | |
146 | that are added to it, so this is a "mutual registration". | |

331 | The following options are used by the post processors: | |
332 | prefer_ffmpeg: If False, use avconv instead of ffmpeg if both are available, | |
333 | otherwise prefer ffmpeg. | |
