VP9 Video Extensions

VP9 Video Extensions

The VP9 video codec is a format developed by Google that allows users to stream high-quality video online. It is a successor to the VP8 format and competes with MPEG's High-Efficiency Video Coding (HEVC).

VP9 has improved compression efficiency, support for higher resolutions, and error resilience. It also supports adaptive streaming technologies.

In addition, VP9 offers better motion compensation than other standards. It employs a directional prediction mechanism that uses two 1D arrays containing restructured upper and left pixels of neighbor blocks.

This ensures that each block has the same information about its neighbor blocks, thus enabling it to correctly decode the contents of these blocks. It also offers inter prediction mode, which uses one eighth pixel motion compensation to improve precision and increase the overall compression rate.

These features allow VP9 to decode video of up to 12K resolutions, which is twice as high as the standard H.264 can handle. It also supports tiled resolutions, which divide up a picture into a grid of tiles along superblock boundaries.

If you're running a Windows 10 build 10547 or later, you can enable the VP9 codec using Edge. The process is easy to follow, but requires a bit of patience if you're using older versions of Windows.

VP9 is a high-quality video compression format that is used by many YouTube streams and Netflix video services. It can compress HD videos to half of their original size, which helps to reduce data usage and make video streaming easier. It is compatible with a wide range of devices, including computers, tablets, smartphones, and TVs.
