我现在通过websocket收到的h264数据,看了一下数据中只有序列参数集(SPS),现在表现不能解码播放出来. 这是为什么 ?
了解到C语言通过ffmpeg 通过 avcodec_decode_video2 函数可以解码。并且能生成图片展示。
前端该怎么处理。

数据中只有SPS是一个罕见的情况,能否更细致地描述一下你的配置?以及这个repo中包含的服务端代码并不好,你可以参考我写的这个用于提供树莓派摄像头里的h.264流的服务端代码。
本repo的核心在于对Broadway.js这个面向浏览器的h.264解码器的websocket包装,它是在前端运用WebGL进行绘图的。有关在前端如何用ffmpeg进行h.264解码等其他技术路线的问题你不该在这里发问。
