#2Youtube probably have stats on viewer-happyness vs bitrate.
I would take a guess that a higher bitrate = longer loading times, and viewers care far more about an extra few second of buffering than they care about audio quality, especially when they don't have the original to compare to.

#3This kind of analysis is interesting but must be considered rapidly outdated since we won't know what's changing behind the scenes at YouTube. Have they ever revealed whether their VCU handles the audio?

Couldn’t you do adaptive Bitrate and start streaming low-bitrate for a few seconds and then switch to higher quality once the video is already playing?

From 2022, so a similar analysis today would be revealing if substantial differences were seen/heard.

Yes it's very possible to do this.
Without seeking support it's trivial, just instruct the encoder to encode with a low bitrate for a few seconds and then increase it.
To support seeking you could encode a low bitrate stream, and a high quality stream, and then a number of ramps between these. So when you seek you start with the low bitrate stream and then after a few time units go on the ramp to the high quality stream.

#8See "Why not use graphs / frequency analysis to compare codecs?" https://wiki.hydrogenaud.io/index.php?title=FAQ#:~:text=Why%...
"I decided that analysis should focus on the higher, more conventional rates – 48k and 44k1" - opus is always 48khz, so that doesn't mean much.

Sure. I think it's hard to control for every relevant factor though. We won't really know what stream they choose to serve under given circumstances to various clients, for example.

The stream is already being split into chunks (identified in the m3u8 file) so encoding tricks like this won't be necessary.
