"""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.
|
||||
throttledratelimit: Assume the download is being throttled below this speed (bytes/sec)
|
||||
retries: Number of times to retry for HTTP error 5xx
|
||||
file_access_retries: Number of times to retry on file access error
|
||||
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.
|
||||
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
|
||||
xattr_set_filesize: Set ytdl.filesize user xattribute with expected size.
|
||||
external_downloader_args: A dictionary of downloader keys (in lower case)
|
||||
and a list of additional command-line arguments for the
|
||||
executable. Use 'default' as the name for arguments to be
|
||||
passed to all downloaders. For compatibility with youtube-dl,
|
||||
a single list of args can also be used
|
||||
hls_use_mpegts: Use the mpegts container for HLS videos.
|
||||
http_chunk_size: Size of a chunk for chunk-based HTTP downloading. May be
|
||||
useful for bypassing bandwidth throttling imposed by
|
||||
a webserver (experimental)
|
||||
progress_template: See YoutubeDL.py
|
||||
|
||||
Subclasses of this one must re-define the real_download method.
