Improving RunVideoDataFetch speed?

[hswlab]

Hi, is it possible to improve the fetch speed for video information in the following call somehow?
var res = await ytdl.RunVideoDataFetch("https://www.youtube.com/watch?v=_QdPW8JrYzQ");

I was wondering if you could limit the information you want to get.
For example, you wand just search for the title, thumbnail and the format list of a single video.

Hey, I think improving the speed of video information fetching would mainly happen on the yt-dlp side as it is responsible for extracting & parsing the video information and passing it in json format. RunVideoDataFetch() uses yt-dlp's --dump-json for fetching video information, which always returns the full data. I'm not aware of an option that extracts & returns partial data to make it faster. Let me know if you have any suggestions regarding this though.

It may entirely depend on the service, but when I call for data manually with yd-dlp.exe as follows:

yt-dlp -J https://www.youtube.com/watch?v=aJRYG93boKc>yt.txt

It takes 3 seconds.

Getting the same information using RunVideoDataFetch takes about 3.2 seconds - so yeah, it sounds like the delay is in the yt-dlp.exe processing/parsing.

You can limit the data returned using yt-dlp.exe by specifying the output, but it is not any faster. Example::

yt-dlp --print "%(title)s" --print "%(manifest_url)s" --print "%(availability)s" --print "%(is_live)s" --print "%(description)s" https://www.youtube.com/watch?v=aJRYG93boKc>yt.txt

And you will see it still takes about 3 seconds so I'm guessing it's doing the same thing as the full fetch, but only printing what you asked for (but not in JSON - just text).
