Used to work fine. Now it fails and says "are you sure the native client is installed ?" Duh, yeah !
The native client passes the connection test. All the paths are correct. And like I said, it used to work (yesterday). I even tried removing it and re-adding it. No dice. Maybe Youtube changed something ?

Looking at the browser console, it says:-

null ExtensionCommon.jsm:740

Unchecked lastError value: Error: An unexpected error occurred ffmpeg.js:14

This works. No need to look elsewhere, fellow collectors. I'm not a shill, it's legit. I'm talking about YouTube Video and Audio Downloader (WebEx). I added that because I see a lot of reviews that say "good add-on" and could be reviewing anything.

Two other add-ons and an application to install just to download a video or convert one? Streamline it or warn people. Do better. Uninstalled.

very quick and good quality app. does the job faster

For some reason when downloading Opus audio only, it's still left as a .webm file, and I have to rename it as .opus. Also, for some reason, dBpoweramp shows less stats on this kind of file when hovering mouse on it, like it doesn't calculate the bitrate like it does for other audio files. However, the hover info works for older files downloaded with this extension when it worked. Newest "good" file for me is from 2020.05.02 (may).

So, there may be something weird about the container. However, the files definitely do contain an opus stream only, and they play fine on MPC-HC and on Musicolet on android.

I don't know if this a ffmpeg issue, I tried downloading using different ones. Or is it even needed for this? For the native client, it says "Install native client (1/2)" and in the test shows 0.9.1 on green background. Not sure what the problem is.

I don't quite understand some of the download option checkboxes, but changing them didn't resolve the issue of opus audio being .webm.

Thanks! its great!!! but subtitle download is insufficiently!

Excellent application. Can download all formats. You need to download companion application to combine video and audio files in HD formats.

10/10 perfect sound quality for audio, no ads and easy to use, definitely recommend this for a youtube downloader

No ads, No QRcode, No watermark, No external server. I love you goddamn

I just tried it and it worked! Thank you so much to those of you who worked to create this. What a gift. Made my life easier and better because I love archiving videos that have helped me so that I can listen to them even when I don't have an internet connection

It works on 1080p for videos that require a log in to access. Even JDownloader and yt-dl can't get videos that need a login any more. YD is working as of April 2020
