|

|
|
||||
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 |
