## 项目历史与用法

Kvazaar is an academic open-source HEVC/H.265 video encoder developed by Ultra Video Group, aimed at portable, research-friendly, and high-performance encoding.

### 项目历史

Ultra Video Group describes Kvazaar as an award-winning academic encoder developed since 2012. The project is implemented in C, optimized with SSE and AVX intrinsics, coordinated by Ultra Video Group, and developed on GitHub.

### 采用历史

Kvazaar's adoption sits between video-coding research and practical media tooling. The official page notes support in FFmpeg and Libav, giving the encoder a route into de facto multimedia frameworks while preserving its role as an open research implementation.

### 使用方式

Kvazaar is used as a command-line HEVC encoder for YUV and Y4M-style workflows, targeting x86, x64, PowerPC, and ARM on Windows, Linux, and macOS. Its goals include coding efficiency close to HM, portability, real-time speed, and optimized compute and memory use.

### 为什么软件包爱好者会关心

Kvazaar is notable because video codecs often arrive as hard-to-package reference software or heavily optimized vendor stacks. Kvazaar gives package managers a BSD-licensed, cross-platform HEVC encoder with an academic provenance and ongoing benchmark-focused release notes.

### 时间线

- 2012: Development began on the academic HEVC/H.265 encoder.
- v1.0.0: Release notes reported major rate-distortion and speed improvements over v0.8.3.
- v2.1.0: License changed from LGPL-2.1 to BSD-3-Clause.
- v2.3.2: Release focused on 10-bit encoding fixes and rate-control/cost-calculation improvements.

### Related projects

- Kvazaar is related to the HEVC/H.265 standard, the HM reference encoder, FFmpeg, Libav, and other Ultra Video Group projects such as uvg266 and uvgKvazaarHW.
