x265 is an open-source video compression software library that is used to encode video streams into the High Efficiency Video Coding (HEVC) format. It is based on the x264 software library, which is used for encoding video into the Advanced Video Coding (AVC) format.
The main goal of x265 is to provide a higher level of compression efficiency compared to its predecessor, x264. This means that x265 can achieve the same level of video quality with a smaller file size or higher video quality at the same file size. This is particularly important for video streaming applications, where smaller file sizes can reduce the amount of bandwidth required to transmit video streams.
x265 uses advanced video encoding techniques such as multi-pass encoding, rate control, and adaptive quantization to achieve its high compression efficiency. It also supports a wide range of features such as 10-bit color depth, high dynamic range (HDR) video, and lossless compression.
Overall, x265 is a powerful and efficient video compression tool that is widely used in the video streaming industry to reduce bandwidth costs and improve video quality.
