Play VP9 videos in any video app on your Windows 10 device. VP9 is a popular video codec for streaming over the internet. These VP9 Video Extensions are designed to take advantage of hardware capabilities on newer devices. For devices that don’t have hardware support for VP9 videos, software support is provided, but the playback experience might vary based on the video resolution and device performance. These extensions also let you encode VP8 and VP9 content on devices that don’t have a hardware-based video encoder.
