Question

WRITE QUESTION HERE
I am calling youtube-dl from C++ and I getting all the download info by parsing the output.
So my question is: how can I detect by a live video download by parsing the output?

I've managed to do it on youutube live video with the following regular expression(C++)
\\[youtube\\]\\s.*\\:\\sDownloading\\sMPD\\smanifest
And for facebook:
\\[facebook\\] playlist .*\\: "
I am not sure though they will always work.

Is there any regular expression for live video downloads in the output(preferably one that comes before youtube-dl creates any file) so I can detect on other websites?

Do something like youtube-dl --dump-json and then test for .is_live

I tried that but not every video will dump a is_live field. Videos from facebook for example, none of those I tested had a is_live field. Videos from YouTube worked well though, but I need a more generalized way.

youtube-dl.exe --dump-json > teast.json https://www.facebook.com/90canal90/videos/1337887116651990/
youtube-dl.exe --dump-json > teast.json https://fb.watch/4xCwFj3KlF/

Live facebook video, at the moment of this writing
youtube-dl.exe --dump-json > teast.json https://www.facebook.com/gaming/omegaheroic/videos/299352561579835/
