please support aria2c

please support aria2c and ensure that progress bar run as usual

MeTube is a GUI for yt-dlp, so all the actual downloading is performed by yt-dlp and MeTube does not have control over that. I see some mentions of aria2c in the documentation, and it appears that you can make it use aria2c via the external_downloader option (which you can set via the YTDL_OPTIONS environment variable), but whether it works or whether download progress is reported is wholly dependent on yt-dlp, and there's nothing MeTube can do in this regard.

Any chance you'll reconsider this? Adding support for aria2 as a downloader (changes what's on stdout) would be huge for performance.

[alexta69]

If it doesn't depend on MeTube, how can I reconsider it?

[karan]

Well metube container will need to include the deps and it'll need to parse the output from stdout to report progress.

[alexta69]

I understand. I don't mind having this in MeTube then, assuming the dependencies aren't too heavy and are cross-platform (i.e. installed via apk or pip). Someone will have to take up the gauntlet and submit a PR, since I don't think I'll have the time to do it myself anytime soon. I'll reopen the issue and label it accordingly.

I just added aria2 to docker (apk add aria2), and set options YTDL_OPTIONS={"external_downloader":"aria2c"}, everything seems to work.

but I don't know what the next step is. fyi

[alexta69]

So the stdout parsing business doesn't need changes, it just works as is? @PikuZheng , do you see the percentage progressing during the download when aria2c is used? (Is it used for sure when you enabled this option in YTDL_OPTIONS?)

[PikuZheng]

yes it works.

INFO:ytdl:waiting for item to download

There is only one problem, the webui doesn't know the download progress, it only knows the download start and finished.

Also according to yt-dlp's issues, downloading with aria2c may not save to subfolders.

[alexta69]

OK, I added aria2 to the Dockerfile, so @10362227 and @karan , if you want to use it, just set your YTDL_OPTIONS as @PikuZheng showed above, and with the mentioned limitations, it will work. stdout parsing will probably never happen, because MeTube doesn't use stdout for progress, it uses yt-dlp's internal reporting via the python module. But if you prefer to use aria2 in any case, you have the option now.
