filter: 'audioonly' does not work on v1.0.2

[mahhov]

Was using an older version in the morning (0.27), and ytdl(<id>, {filter: 'audioonly'}) worked fine. I updated to version 1.0.2, and now I get No formats found.

From what I can tell, this is the relevant code:
fn = (format) => !format.bitrate && format.audioBitrate;

node-ytdl-core/lib/util.js

Line 188 in df7c80b

fn = (format) => !format.bitrate && format.audioBitrate;

Here are console.logs of the available formats for a particular video:

const ytdl = require('ytdl-core');
ytdl.getInfo('QvtjAoFBmVg', (err, info) =>
    console.log(JSON.stringify(info.formats)));

Version 0.27, note the last 4 formats have bitrate: null:

Version 1.0.2, note that now all 23 formats have a bitrate:

bitrate is null if it's a audio format but audioBitrate not.
I dunno but the line you refered is correct so something isn't right
And please, can you send me the video url ?

[mahhov]

For this one example at least, checking
format.mimeType.startsWith('audio') && format.audioBitrate or !format.qualityLabel && format.audioBitrate would both work, but I'm not sure if that's valid for all videos.

I checked with an another video but fent verification is correct but something isn't right

[mahhov]

The video ID is in my snippet, QvtjAoFBmVg.

bitrate is null if it's a audio format

It has 23 formats available, the last 4 are audio-only but have non-null bitrate with v1.0.2, as seen in my 2nd JSON gist.

Problem noticed, some audio formats contains bitrate value, i will try an another verification

[RocoGreen]

So the fix is:
fn = (format) => !format.qualityLabel && format.audioBitrate
