Description

Tartube is a GUI for youtube-dl. It uses the --dump-json option to collect a list of videos, without downloading the videos themselves.

Many videos produce errors. For example, at the time of writing, this video has not gone live, so YouTube generates an error:

youtube-dl --dump-json https://www.youtube.com/watch?v=UjMTHJnwUYc
ERROR: This live event will begin in 4 days.

youtube-dl does not tell us which video has produced the error. It does not tell us the video ID anywhere in the log.

(In this example above, we gave youtube-dl the URL of the video, but the same problem applies if we give youtube-dl the URL of a channel or playlist.)

My feature request is this: every error should contain the ID of the video that produced it.

@dstftw, are you sure this is a duplicate? This was a request for URLs, not video IDs.
