36 | """File Downloader class. |
37 | ||
38 | File downloader objects are the ones responsible of downloading the | |
39 | actual video file and writing it to disk. | |
40 | ||
41 | File downloaders accept a lot of parameters. In order not to saturate | |
42 | the object constructor with arguments, it receives a dictionary of | |
43 | options instead. | |
44 | ||
45 | Available options: | |
46 | ||
881e6a1f PH |
47 | verbose: Print additional info to stdout. |
48 | quiet: Do not print messages to stdout. | |
49 | ratelimit: Download speed limit, in bytes/sec. | |
c487cf00 | 50 | continuedl: Attempt to continue downloads if possible |
51d9739f | 51 | throttledratelimit: Assume the download is being throttled below this speed (bytes/sec) |
881e6a1f | 52 | retries: Number of times to retry for HTTP error 5xx |
205a0654 | 53 | file_access_retries: Number of times to retry on file access error |
881e6a1f PH |
54 | buffersize: Size of download buffer in bytes. |
55 | noresizebuffer: Do not automatically resize the download buffer. | |
56 | continuedl: Try to continue downloads if possible. | |
57 | noprogress: Do not print the progress bar. | |
881e6a1f PH |
58 | nopart: Do not use temporary .part files. |
59 | updatetime: Use the Last-modified header to set output file timestamps. | |
60 | test: Download only first bytes to test the downloader. | |
61 | min_filesize: Skip files smaller than this size | |
62 | max_filesize: Skip files larger than this size | |
63 | xattr_set_filesize: Set ytdl.filesize user xattribute with expected size. | |
34488702 | 64 | external_downloader_args: A dictionary of downloader keys (in lower case) |
65 | and a list of additional command-line arguments for the | |
66 | executable. Use 'default' as the name for arguments to be | |
67 | passed to all downloaders. For compatibility with youtube-dl, | |
68 | a single list of args can also be used | |
7d106a65 | 69 | hls_use_mpegts: Use the mpegts container for HLS videos. |
073cca3d | 70 | http_chunk_size: Size of a chunk for chunk-based HTTP downloading. May be |
b54d4a5c S |
71 | useful for bypassing bandwidth throttling imposed by |
72 | a webserver (experimental) | |
819e0531 | 73 | progress_template: See YoutubeDL.py |
