Increase thumbnail resolution (or make configurable)

[aeharding]

Describe the problem to be solved

A large and growing segment of computer displays are running at 2x and larger pixel densities.

Currently, PeerTube thumbnail images are the same size as the actual container (1x):

However, this leads to thumbnails that look noticeably blurry/low quality.

Describe the solution you would like

Double the size of thumbnails, or greater (to allow for more flexibility in customizing the UI, for example zoom animations).

This would also align with what other video streaming platforms are doing, such as YouTube:

Lastly, mobile devices already use the larger PREVIEWS_SIZE as thumbnails, so increasing THUMBNAILS_SIZE would have no impact on mobile devices.

Similar issue, but for PREVIEWS_SIZE: #5464

Hello, We suffer from the same prob, and we would love to have better quality resolution for thumbnail. Maybe a way to configure it on server side (if not already available ?)

If already exists, I would be interesting to know how to do it .

Thx in advance

I'd like to see this as well.

I am planning to do a PR for making the PREVIEWS_SIZE and THUMBNAILS_SIZE configurable from some of the configs. The default values would stay the same, so we maintain backwards compatibility:

// Videos thumbnail size
const THUMBNAILS_SIZE = {
  width: 280,
  height: 157,
  minWidth: 150
}
const PREVIEWS_SIZE = {
  width: 850,
  height: 480,
  minWidth: 400
}

What do you think ?
