Video Playback broken in Monterey 12.2 Update

I had a similar problem with my 2015 Macbook Air. Videos weren't working in my primary browser (Google Chrome) or my backup browser (Safari). I contacted Apple support, and the first suggestion they gave me appeared to work for both browsers.

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in.
3. You might be asked to log in again. On either the first or second login window, you should see "Safe Boot" in the upper-right corner of the window in red lettering.

When I reopened Chrome, the websites that I tried would almost refuse to load, but after about 5 minutes, I finally got a website to load and the playback worked. Safari worked just fine almost immediately.

Once you check and see if the videos work, you should restart your Mac to get out of safe mode. When I opened up Chrome after the restart, everything worked as it normally should.

I hope this helps.

In addition to what lllaass said:

“Once again” is relevant… so it was broken for you sometime before?

When?

I am thinking that there may be something peculiar to your installation. The best way to find out is to run the diagnostic tool Etrecheck and post its report here so we look for possible causes.

FWIW video has been playing here every day in many different applications without issues, across many OS versions.

LawMichigander - what exactly was it doing?

I've been having issues with videos playing on Reddit on my 2017 iMac with Monterey, and tonight my wife told me (and showed me) she has similar issues on her 2021 MBP with Monterey on Facebook.

In both cases, the video will start normally, then speed up and get jerky, and then stop.

What is source and extension of the video?
