   Chrome 138 – Update on Video Freezing and Crashing Issues Two separate issues have occurred in recent weeks: video freezing/spinning, and browser crashes. After extensive analysis, both have been traced back to changes introduced in Chrome 138. 1. Video freezing or spinning: Chrome 138 was the cause of this issue. We’ve deployed updates to our video servers to resolve it. We’re confident this issue is fully addressed. 2. Browser crashing: This issue is also linked to Chrome 138. We have traced this Chrome bug to their AV1 video codec implementation, and have a working thesis that this is correct. We have disabled the AV1 codec in production, reverting to VP9. In our internal testing, this prevents Chrome from crashing. We continue monitoring this to confirm its effectiveness across all environments. 3. It’s unclear whether these issues were present in early versions of Chrome or were introduced after the stable release. Although we already test beta releases of Chrome, we are expanding our QA process to include longer, more detailed testing across a broader range of devices and browser versions to help us catch similar issues earlier in the future.
