Test video codec support including H.264, VP8, VP9, AV1, and other video formats. Check hardware acceleration, codec capabilities, and video playback compatibility. Essential for video streaming applications and multimedia web apps.
Video codecs compress video data, with modern codecs like AV1 providing 30% better compression than H.264 while maintaining quality. Hardware acceleration uses the GPU to decode video, reducing CPU usage by up to 90% and enabling smooth 4K playback. This tester reveals which codecs your browser and device support, and whether hardware acceleration is available.
Start with the live tester below. Supporting details, FAQs, and troubleshooting guidance are placed after the tool so the main action is easier to find and use immediately.
Test which video codecs and formats are supported by your browser.

Helpful questions
Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.
Open the live video codec test on this page and follow the prompts shown in the tester area. The tool runs directly in your browser, so you can check your device without installing additional desktop software or signing in.
Check browser permissions, confirm the device or browser feature is enabled, and reload the page if needed. Many browser-based testers depend on permission prompts, secure context support, or hardware access that must be approved before the test can run fully.
Video streaming - verify codec support. It can help you confirm whether the issue is caused by the hardware itself, a browser permission setting, or a system configuration problem before you spend more time debugging.
