[Support]: msjpeg stream distortion

[bdoiron74]

Checklist

• I have updated to the latest available Frigate version.
• I have cleared the cache of my browser.
• I have tried a different browser to see if it is related to my browser.
• I have tried reproducing the issue in incognito mode to rule out problems with any third party extensions or plugins I have installed.

Describe the problem you are having

When the ui drops back to msjpeg mode for live view I often see this:

Notice how the color and I guess luminosity are out of sync. Live view and recordings do not show this issue.

I am currently using two streams, one for recording (recording=1920x1080@8fps, live=856x480@24fps) but I think I've also seen this using just the 856x480@24fps for both live and record.

Steps to reproduce

Nothing fancy - I'm just leaving the frigate live view running. I'm not sure exactly what causes it to drop back to msjpeg mode, I usually just refresh the page.

See the FAQ, Usage question 15.

[NickM-27]

Yes that's expected

[bdoiron74]

Can you specify live height under individual cameras like detect dimension?

[hawkeye217]

Yes

Thanks guys - I'm all sorted. You guys are doing great work!
