Description

I would like to download a video and get the JSON with full info about it and see the progress within one youtube-dl session.

There're these lines in __init__.py that prevent printing of progress:

any_printing = opts.print_json
...
    'quiet': (opts.quiet or any_getting or any_printing),

Probably a new option would help. There's --no-progress option, so maybe an enforcing option might help, something like youtube-dl --print-json --progess $url .

This will introduce ambiguity since both JSON and progress are written to stdout and it would be impossible to safely classify whether new line is JSON or progress data.
What you can do is to use --console-title to show progress in title bar.

What you can do is to use --console-title to show progress in title bar.

Do you think there are any other approaches? I need this to automate some workflow, so there are no title bars in my case.

What if we add a [json] prefix before JSON output, similar to [download] and others?

[dstftw]

You can just embed it in python code and receive progress via a hook.
No prefixes can be added since this will break existing clients.

Thanks for your quick replies!

I'm using youtube-dl from a different programming language, and it will make things a bit harder I think. But anyway, thanks for the suggestion. I'll add a new comment if I come up with a good solution. Until then I'll just call youtube-dl twice: 1) to get a JSON and 2) to download a video.
