Use JSON-RPC interface to download the video through aria2

[wanglongqi]

Currently, download through aria2 is implemented in external downloader. I do not like the interface in the terminal, and aria2 has a pretty good JSON-RPC interface, which can be managed from web interface. I would like to be able to see the download list and speed through web browser instead of terminal window, since they are easier to read and looks prettier.

If the flag --enable-rpc is all you need to enable JSON-RPC, does adding it you youtube-dl with the --external-downloader-args option work? If not, could you post the command you would use from the command line to make aria2c use the JSON-RPC

[wanglongqi]

Maybe I do not use aria2 the right way. I have a JSON-RPC server running on my computer, rerun aria2c with --enable-rpc will print error like IPv4 RPC: failed to bind TCP port 6800.

Ok, so we should conect to the server and execute the JSON-RPC commands?

[wanglongqi]

Yes, I think it should be not hard to implement. Here is an example from document:

>>> import xmlrpclib
>>> s = xmlrpclib.ServerProxy('http://localhost:6800/rpc')
>>> opts = dict(dir='/tmp',
...             header=['Accept-Language: ja',
...                     'Accept-Charset: utf-8'])
>>> s.aria2.addUri(['http://example.org/file'], opts)
'1'

The main problem is how to assemble this function into current framework. Maybe add another external downloader or read configuration file.

Such features is quite useful when using tools like Aria2GUI.

+ Very useful feature.

Is there any update on the feature? Thanks ❤

aria2p is a client that sends the RPC commands to an aria2 server. We could try to symlink aria2 to aria2p in order to fool youtube-dl into using aria2p instead. Where is the aria2 executable used by youtube-dl located?

@frogger72 maybe you could add a new external downloader using aria2p instead of aria2c? https://github.com/ytdl-org/youtube-dl/blob/master/youtube_dl/downloader/external.py#L181

Why youtube-dl doesn't provide its own JSON-RPC interface? Much better than passing command line args to the script.
