"""File Downloader class.
|
|
||||||
|
|
||||||
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

|
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
|
||||||

Subclasses of this one must re-define the real_download method.
