Video opened through rerun looks distorted and has wrong colors

[pablovela5620]

Describe the bug

Something went wrong with showing an av1 encoded video. Here are is what it looks like in rerun and what it looks like in vlc

Rerun

Screen.Recording.2024-11-01.at.1.59.24.PM.mov

VLC

Screen.Recording.2024-11-01.at.1.59.48.PM.mov

To Reproduce
Steps to reproduce the behavior:

1. Open video via rerun $Path to video

here is the video that I used that caused problems
https://huggingface.co/datasets/pablovela5620/rerun-bug-video/blob/main/combined-av1.mp4

Desktop (please complete the following information):

• OS: Mac OS 15.1 (24B83)

Rerun version

rerun-cli 0.19.0 [rustc 1.79.0 (129f3b996 2024-06-10), LLVM 18.1.7] aarch64-apple-darwin, built 2024-10-21T16:15:46Z
Video features: av1 nasm

Additional context
This was after I merged some mp4 files and reenocded them to av1 using the following command

ffmpeg -i combined.mp4 -c:v libsvtav1 -preset 10 -crf 35 -c:a copy combined-av1.mp4

I get the same problem on the native build:

The web-viewer plays it perfectly though

Zooming in:

Looks like something goes wrong with the chroma upsampling 🤔 Other 4:2:0 videos look correct though, so I wonder if this is a bug in rav1d, i.e. reporting the wrong chroma format?

Oh shit, I missed this:

This is therefore a duplicate of:

• Support HDR video (shows wrong color or glitches today) #7594

It makes me think we should just refuse to play such videos though, instead of showing something so obviously wrong

[emilk]

I'll add a warning to the selection panel, and maybe see if there is an easy way to at least get almost correct colors

For some reason I also didn't see the pop up on my mac, when I tested on my linux machine it showed up!
