[Feature Request] Choose the default playback quality / bitrate ?

[EVOTk]

Hello,

Would it be possible to propose to Memories users to choose the default playback quality for videos in the settings?

Currently, the video always starts on Auto, for users with a weak connection it could be interesting to force this pre-selection directly.

Also, I take advantage of the fact that we are talking about quality but not bitrate, however for a remote reading, I think that it is more interesting to propose a limitation of resolution but also of bitrate.

Jellyfin example :

Thanks

With the stable update, the quality you select will be persisted the next time you play a video. That should be equivalent to this.

EDIT: unfortunately there's no easy way to select the bitrate without potentially increasing the server load significantly (also the player doesn't support it, so probably need a lot of ugly patchwork). It's easier for jellyfin because AFAIK they don't do adaptive streaming, but only let the user select a bitrate.

It's perfect thanks :)

For Jellyfin, there is an "Auto" setting but I don't know how it works "behind", but this was just an example.

I'm not sure either, should be interesting to find out.

Closing this for now anyway.

Hello, strangely I had this error :

ls -alh exiftool-bin                                                                                                                                                                                     root@citrouille [09:08]

chmod +x exiftool-bin/go-vod-amd64 resolve issue, Now it works

Also I take advantage of it because I see something else:

I have set the playback to 360p. when I go to another video, the playback then starts in 1080p, only to be killed and started in 360p. Is this the normal behavior?

Good catch. Filed in #193 The initial quality switch is a known bug. I'm still trying to find a fix for it.

Ok ! Thanks for the answer !
