Slow/unstable loading times for high quality video with proxy mode

[mark9064]

Using https://invidio.us as the instance with proxy mode and dash enabled, set to 1080p quality.

Load times for content can be really slow (~8s receiving 3MB of data, inet is ~6MB/s) and sometimes the requests take dramatically longer (more than a minute).

Example attached:

Edit: Getting 500s for the media requests sometimes too which unrecoverably halts playback (I usually fix this by changing the quality and then changing it back)

i think this is something that the player should be responsible for. i wished players showed buffer information instead of a fancy spinning animation. maybe check out video.js and if something like this could be achieved with the current version and if not create a feature request there

The issue is likely high load. Does this happen on https://dev.invidio.us or another instance?

I also notice this on my instance. Invidious, especially with proxy enabled, needs a lot bandwidth and also a lot CPU. This probably is just how it works

On another instance, it seems to be fine. I suspected it may be high load. Guess there isn't much that can be done about this?

Currently looking at ways to speed up the current implementation. Just pushed out ab4df7e which should hopefully help with this.

From #562:

I've pushed out e5fa5df which should improve download speed significantly. From some brief testing most files download about 10x faster (limited by local network), although I would appreciate other reports.

In short, YouTube will throttle downloads when requesting segments >10MB (see Rudloff/alltube#217, or ytdl-org/youtube-dl@e4a6091). For downloads this commonly results in throttling down to ~300Kb or lower.

Closing in favor of #616.
