title: Raspberry Pi 4 Video Tearing Problem Playing on Chromium
body: <p>I have a web application that displays video. I'm running this on Raspberry Pi 4, OS Raspbian Buster.</p>
  
  <p>My app plays a video with 1080p resolution on the screen using Chromium. The video works smoothly in the VLC player. When the video runs on Chromium, it tears the video.</p>
  
  <p>When I examine the processor status during tearing, CPU usage goes up to %80 - %90, resulting in poor performance. I couldn't solve this problem by doing hardware acceleration in chrome settings (chrome://flags)</p>
  
  <p>I've had this problem in Raspberry Pi 3 before. I solved this problem by installing a codec pack. However, in Raspberry Pi 4, this codec support seems to be incompatible. So there is no codec pack.</p>
  
  <p>Is this a general problem? I've been looking for ways to solve this problem for quite a long time. Is there a method you know? I am open to any kind of support that has previously encountered such a problem or can provide information about the solution.</p>
  
  <p>I look forward to your suggestions and ideas.</p>
  
  <p>Thank you in advance for support.</p>
