Add Opus support for download + metadata

[Shnxxx]

The app works great! I am loving it already and being used 100% of the time I am using my PC. But we can't deny that even how great the application is, there still some external problems like Internet connectivity. We lost connection for no reasons, or Google is messing us up again. The download plugin is great! It allows me to download the music to an .mp3 format. But these days, there are lots of better formats now that is supported widely. There's .aac, .flac, m4a, .wav, .opus, and such...

Opus is far superior now to .aac and .mp3, which are being widely used too. Opus is a lossy audio format yet produces far better quality and lower size compared to .mp3, .aac, and vorbis.

I would like to request to add an Opus support, if possible. Or at least let us choose what format what we would like to download the music for us audiophiles who wants to store the highest quality possible yet low-sized audios. Since YouTube supports already opus format. Thank you in advanced!

Hey @Shnxxx, thanks for the feedback! The latest prerelease adds support for custom file extensions - using it, you can convert to opus with the following options (in Options > Advanced Options):

…
"downloader": {
    "enabled": true,
    "extension": "opus",
    "ffmpegArgs": [
        "-acodec",
        "libopus",
        "-b:a",
        "128000"
    ]
},
…

128000 is for 128kbits/s but you can set another bitrate - Feel free to give it a try!

Other audio formats are also possible by setting a different extension and custom FFmpeg options - a list of available encoders is available in ffmpegwasm/ffmpeg.wasm#61 (feel free to post in this issue if you need help for another format)

Thank you for your response! I used the code you have given and when I tried to download, I am only getting 0 KB files and is still in .mp3 extension. Any ideas?

Hey @Shnxxx, thanks for the feedback! Settings look good, have you restarted after changing the setting + are you using v1.8.1 (and not the latest v1.8.0)? You can check with About YouTube Music in the menu.
I had the same issue (0KB file) with 1.8.0, that's why I released v1.8.1 (and with "extension": "opus", your final file should be a .opus, not a .mp3).

If things are still the same, then it might be another issue worth investigating!

Thank you! After doing the fix last time, I looked at the release section but there is no new version so I did not change anything in the app except the configuration. Didn't notice there was a pre-release. My mistake 😅

The download works fine now! I am just wondering, does the download do is downloading the audio in .mp3 and converts it to .opus? If yes, is it possible to download the highest possible quality of the audio? Based on a web search, YouTube Music uses .aac @ 256Kbps. Is it possible to download that directly then convert to .opus?

Also, Is it possible to add more metadata on the audio I've downloaded? For example, I just downloaded U got that - Halogen and the filename was only U got that.opus. Also, when I looked at the details under properties of the file, there were no other details except the Name, Audio Sample rate, Length, Size, and Date. Or is it on the YouTube Music already? They don't include metadata?

One more thing, if you are a premium user of YouTube Music, which I am not, you can stream or download High Quality audio by setting it up the playback settings to High or Always High. When I tried it to the app, it is the same in the browser. Is it possible in the future to allow us to stream/download high-quality music with the app like a premium?

Thank you again! I still have lots of thoughts but I think it is too much for now. 😅

Hey @Shnxxx, thanks for the feedback! In latest version 1.9.0, all downloaded songs should now have the artist/title metadata!
Feel free to give it a try and update the issue if necessary!

[Shnxxx]

Thank you @th-ch! I tried downloading a song and the metadata is there, it works great! But is it possible to modify how the app names the filename?

Is it possible to add the artist too? From 'Iris.opus' to 'Iris - Goo Goo Doll.opus'.

Hey @Shnxxx, thanks for the feedback!

I am just wondering, does the download do is downloading the audio in .mp3 and converts it to .opus? If yes, is it possible to download the highest possible quality of the audio?

About quality, the highest audio quality is downloaded (seems to be 160kb/s by default) and then converted to the format you configured (so you configured opus, no intermediary mp3).

Is it possible to add the artist too?

Sure! Added the artist - title file format in 37289b9, it will be available in the next version!

I figured rather than open a new issue I would just ask here - is there some way with the new options to have it not transcode at all, just save whatever the highest quality file is that YTM is serving up? It can of course be done using youtube-dl but I would love to be able to do it from within this app, it's so convenient. Thanks!

Hi All

Could someone tell me how to add the correct code to up bit rate on MP3s, My config looks like this but I don't know which arguments to change/add

Many thanks
