Move FileDownloader to its own module and create a new class for each download process
A suitable downloader can be found using the 'get_suitable_downloader' function. Each subclass implements 'real_download', for downloading an info dict you call the 'download' method, which first checks if the video has already been downloaded

File downloader objects are the ones responsible of downloading the

actual video file and writing it to disk.
|

|

File downloaders accept a lot of parameters. In order not to saturate
|
||||
the object constructor with arguments, it receives a dictionary of
|
||||
options instead.
|
||||
|
||||
Available options:
|
||||
|
||||
verbose: Print additional info to stdout.
|
||||
quiet: Do not print messages to stdout.
|
||||
ratelimit: Download speed limit, in bytes/sec.
|
||||
retries: Number of times to retry for HTTP error 5xx
|
||||
buffersize: Size of download buffer in bytes.
|
||||
noresizebuffer: Do not automatically resize the download buffer.
|
||||
continuedl: Try to continue downloads if possible.
|
||||
noprogress: Do not print the progress bar.
|
||||
logtostderr: Log messages to stderr instead of stdout.
|
||||
consoletitle: Display progress in console window's titlebar.
|
||||
nopart: Do not use temporary .part files.
|
||||
updatetime: Use the Last-modified header to set output file timestamps.
|
||||
test: Download only first bytes to test the downloader.
|
||||
min_filesize: Skip files smaller than this size

max_filesize: Skip files larger than this size
