STN Defaults to lower quality audio

[SyCoREAPER]

If a standard video is set to opus, (highest quality codec), it defaults to opus for 5.1 YouTube videos which does not support 5.1, so you only get 2.0 audio.

If you go and change it on the 5.1 video to ac3 or ec3, regular videos revert to mp4a instead opus.

Its stuck in the loop. Either higher quality 2.0 and no 5.1 or 5.1 and lower quality 2.0 sound.

Video titled: 5.1 Dolbly Surround Test (by TheMessengerOfEldo) is a good example of for a free 5.1 encoded YouTube video.

I faced similar problems, but I'd explain it a different way:

1. I'd like to have separate preferences for audio tracks:

• Stereo: opus or mp4a
• 5.1: disabled/ac3/ec3/mp4a

My choice would be opus/ec3, which is currently not possible to do only once.

2. I'd also like to have separate preferences for video streams:

• Max. resolution and frame rate
• Preferred video codec for SDR
• HDR: enable/disable (even if it is not the preferred codec, or SDR stream has higher bitrate!)

My choice would be 4K/60Hz, AV01, enable. But its not possible, because HDR requires VP9. Also, there are streams with higher VP9 bitrate with no HDR, than VP9 with HDR.

If it is too much of work, I'd suggest to add a couple of buttons (5.1 and HDR, disabled if not available), or at least icons to show 5.1 and HDR availability. Right now, I have to set mp4a/vp9+hdr, while most of time I watch SDR with stereo sound.

Thanks in advance!

Some interesting ideas. Just two things I wanted to point out.

Higher Bitrate doesn't always mean better video, it depends on how Google encodes it and how it was uploaded.

The second part, 4K@60+HDR+5.1 in AV1 is entirely possible, just not many devices can do it. Amazon FireTV 4K Max and Firecube 3 are able to fully decode AV1

Would be really nice to have the same option for audio as for video now with choosing prefered audio stream.
