VLC as always saves the day. Most recently for me when you want to watch HDR UHD ripped to 1080p. With plex, this becomes a problem you need to buy a plex pass for and more significantly, must have a '16 Intel CPU or newer to be able to remap it while VLC does so in the fly.
Details: In plex, the colors are so washed out it looks like a black and white movie. In VLC, the colors hit you like
Addition: I tried two remedies while packing with handbrake. BT.709 colorspace and a custom one from reddit. Both lead to the movie being so dark that you cant see most of the details.
Conclusion: VLC being open source, we should be able to see what they are doing and copy this behavior. if plex wont do it without payment, this could be huge for jellyfin for example.
Anyone with actual knowledge who can shed light on this?
Yes. Jellyfin is mostly awesome, now. I would recommend it to everyone.
Plex has been around a long, long time and the experience from backend to the front is still for the most part unmatched. It was really nice to have proper full featured clients on all devices. Built in skipping intros and ability to download content for offline use was really nice and would be very useful for me at this time.
I have a lifetime pass from the very beginning and was spare change compared to what they charge now. A common misconception is they took away the ability to log in locally on the lan without phoning home. You can still do that. But ultimately I decided to move on.
