Missing Format Details for Livestreams

[repository]

Hello, for certain livestream formats, ytdl-core is unable to retrieve details about the format, why is this so?

Here is an example, note itag 301.

ytdl.getInfo("https://www.youtube.com/watch?v=idUGBcSEurY");

However, youtube-dl is able to get information for that format

version: "ytdl-core": "^4.5.0"

Is there anything I can do about it?

looks like 301 is a relatively new format that's not already in ytdl-core's list of formats.

although we should be parsing all of its properties from the m3u8 master file where it's first found. those properties weren't there before

#EXT-X-STREAM-INF:BANDWIDTH=5552610,CODECS="mp4a.40.2,avc1.4d402a",RESOLUTION=1920x1080,FRAME-RATE=60,VIDEO-RANGE=SDR,CLOSED-CAPTIONS=NONE

Cool, I've added it to the formats myself and I'm using it locally now. https://github.com/repository/node-ytdl-core/commit/906414bd60d004cd5a0f12d7059d56dd094bddcc

I don't know how you calculate video bitrates, so I just guessed based off the other formats
