What is VP8?
VP8 is a video compression format to provide high-quality video compression with efficient bandwidth usage, making it an ideal option for streaming video applications. It is an open and royalty-free codec, meaning anyone can use it without paying licensing fees.
It achieves its video compression goal by using various compression techniques to reduce video file size while maintaining the original content's quality.
How does VP8 work?
VP8 uses various compression techniques to reduce video file size while maintaining the original content's quality.
These techniques include intra-frame prediction, inter-frame prediction, and entropy coding. Intra-frame prediction involves compressing individual frames within a video, while inter-frame prediction involves compressing the differences between frames. Entropy coding is used to compress the data further, reducing the overall size of the video.
