"""YoutubeDL class. |
|
|
|
YoutubeDL objects are the ones responsible of downloading the |
|
actual video file and writing it to disk if the user has requested |
|
it, among some other tasks. In most cases there should be one per |
|
program. As, given a video URL, the downloader doesn't know how to |
|
extract all the needed information, task that InfoExtractors do, it |
|
has to pass the URL to one of them. |
|
|
|
For this, YoutubeDL objects have a method that allows |
|
InfoExtractors to be registered in a given order. When it is passed |
|
a URL, the YoutubeDL object handles it to the first InfoExtractor it |
|
finds that reports being able to handle it. The InfoExtractor extracts |
|
all the information about the video or videos the URL refers to, and |
|
YoutubeDL process the extracted information, possibly using a File |
|
Downloader to download the video. |
|
|
|
YoutubeDL objects accept a lot of parameters. In order not to saturate |
|
the object constructor with arguments, it receives a dictionary of |
|
options instead. These options are available through the params |
|
attribute for the InfoExtractors to use. The YoutubeDL also |
|
registers itself as the downloader in charge for the InfoExtractors |
|
that are added to it, so this is a "mutual registration". |
|
|
|
Available options: |
|
|
|
username: Username for authentication purposes. |
|
password: Password for authentication purposes. |
|
videopassword: Password for acces a video. |

|
Unsuitable videos for the given age are skipped. |

|
* key: The name of the postprocessor. See |
|
youtube_dl/postprocessor/__init__.py for a list. |
|
as well as any further keyword arguments for the |
|
postprocessor. |
|
progress_hooks: A list of functions that get called on download |
|
progress, with a dictionary with the entries |
|
* status: One of "downloading", "error", or "finished". |
|
Check this first and ignore unknown values. |
|
|
|
If status is one of "downloading", or "finished", the |

|

listformats: Print an overview of available video formats and exit. |
|
list_thumbnails: Print a table of all thumbnails and exit. |
|
match_filter: A function that gets called with the info_dict of |
|
every video. |

If it returns a message, the video is ignored. |
|
If it returns None, the video is downloaded. |
|
match_filter_func in utils.py is one example for this. |
|
no_color: Do not emit color codes in output. |
|
|
|
The following options determine which downloader is picked: |
|
external_downloader: Executable of the external downloader to call. |
|
None or unset for standard (built-in) downloader. |
|
hls_prefer_native: Use the native HLS downloader instead of ffmpeg/avconv. |
|
|
|
The following parameters are not used by YoutubeDL itself, they are used by |
|
the downloader (see youtube_dl/downloader/common.py): |
|
nopart, updatetime, buffersize, ratelimit, min_filesize, max_filesize, test, |
|
noresizebuffer, retries, continuedl, noprogress, consoletitle, |
|
xattr_set_filesize, external_downloader_args. |
|
|
|
The following options are used by the post processors: |
|
prefer_ffmpeg: If True, use ffmpeg instead of avconv if both are available, |
|
otherwise prefer avconv. |
|
exec_cmd: Arbitrary command to run after downloading |
