Hi I'm using the youtube-dl as part of an other process and I searched if the command line has any option to print the output progress at a diserd format but, there's no one. So I'm wondering if it would be possible to add an option to choose a desired output format of process for get the % of downloaded, totalsize, downloading current speed, etc into personalized form to pass to any external program for parse just like making string.split(" ") to choose the desired column.
Thanks in advance

There is a mechanism to reach progress data via progress hooks available from python code https://github.com/rg3/youtube-dl#embedding-youtube-dl. You can write a wrapper script in python that will translate it in any format you like. Is that enough?

[didix16]

Well since I'm not using python, I cannot make any wrapper python based. I'm using nodejs to invoke a child process that call youtube-dl. So I pick up the output and I parse it, at the moment with a regular expression, but I would pass as command line argument to youtube-dl some option to format the output to just pick up it and don't make any kind of regular expression. For example, in the blikd command you can choose what data you want to show and in which format.

Could you give more details, for example how to specify the format and what the output should look like?

For me such a feature sounds highly application-specific but not for generic uses, so youtube-dl may not implement it. Writing a Python wrapper is never difficult. Feel free to ask questions if something goes wrong.

[didix16]

Well actually there's a -o option to format the final file downloaded which hace many predefined values such %(id), %(title), %(ext), etc... So what I say is specify, say -O or --output or -stdout, whatever you want, a template format to style the output, selecting a specified variables like %(download_speed), %(eta), %(progress), anything else, for format the output, overriding the predefined which actually is showing [download] blablabla...
And some other kinda debugging words also separated with more than 1 space. I want format the output to just make a simple split by space or just pick up an specified field or the fields that I want.

One example could be: youtube-dl -O "%(download_speed) %(eta)"

[bugs181]

Came here to request the same feature as OP. I'm honestly surprised this hasn't gained any traction. Plenty of other applications (UI specifically) wrap youtube-dl and could improve if this option was available. Even outputting bytes instead of a formatted percentage (progress) or MiB (file size) would be useful at this juncture.
