It turned out that, despite the program working without apparent errors, the code for setting the language was completely wrong. First, it didn't run unless some form of authentication was performed. Second, I misstyped _LANG_URL as _LOGIN_URL, so the language was not being set at all! Amazing it still worked.

File downloader 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, file downloader objects have a method that allows
|
|
InfoExtractors to be registered in a given order. When it is passed
|
|
a URL, the file downloader handles it to the first InfoExtractor it
|
|
finds that reports being able to handle it. The InfoExtractor returns
|
|
all the information to the FileDownloader and the latter downloads the
|
|
file or does whatever it's instructed to do.
|
|
|
|
File downloaders 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 get_params()
|
|
method for the InfoExtractors to use. The FileDownloader 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.
|
|
usenetrc: Use netrc for authentication instead.
|
|
quiet: Do not print messages to stdout.
|
|
forceurl: Force printing final URL.
|
|
forcetitle: Force printing title.
|
|
simulate: Do not download the video files.
|
|
format: Video format code.
|
|
outtmpl: Template for output names.
|
|
ignoreerrors: Do not stop on download errors.
|
|
ratelimit: Download speed limit, in bytes/sec.
|
|
nooverwrites: Prevent overwriting files.
