适合已有开源鸿蒙底层多媒体开发经验，或能处理音视频容器、音频解码、视频解码实现的开发者或团队。参赛者需要按具体赛题分别完成格式解封装、音频解码或视频解码方向的作品。
If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
开源鸿蒙多媒体框架
音视频容器解封装
音频编解码原理
视频编解码原理
C/C++ 性能优化
媒体格式调试
The real friction is usually not library usage. It is validation, time allocation, and task framing.
核心难点是为开源鸿蒙实现或优化特定复杂媒体格式的原生、高效解码支持，而不只是调用现成播放器接口。作品需要在具体赛题页面提交，参赛前还需确认自己选择的是解封装、音频解码还是视频解码赛题。
