How to solve the problem of splash screen when the main and sub code streams of easygbs are h.265?

National standard video cloud service EasyGBS The platform is based on the national standard GB28181 The platform protocol , The achievable video capabilities are ： Live in real time 、 Video recording 、 Voice talk 、 Cloud storage 、 Retrieval and playback 、 The alarm 、 Cascade, etc . The platform supports the whole terminal processing of the accessed video stream 、 Platform wide distribution , The video streams distributed include RTSP、RTMP、FLV、HLS、WebRTC Equiform .

Recently, there are user feedback , stay EasyGBS The main and sub code streams used on the platform are h.265 when , There will be a splash screen phenomenon when switching , also h.265 Switch h.264 when , Playback failure will be displayed . After receiving the feedback, the technicians immediately carry out troubleshooting , Today, let's share with you the solution .

When switching primary and secondary code streams , from tcp After the connection reads the stream data , Use it directly h.264 parse Split output h.264 The frame data , The encoding type of the stream is not determined , This leads to the above phenomenon .

therefore , When the coding type changes , You need to use the corresponding library for segmentation according to different codes ：

Then judge whether it is I frame , And update the mediaInfo Information , Pictured ：

National standard GB28181 Protocol video platform EasyGBS It can be used as a capability platform to provide interface calls for the business layer , It can also be used directly as a business platform . The platform is based on cloud edge end integrated management , Powerful data access 、 Processing and distribution capabilities , Strong compatibility 、 High openness , Easy deployment , Functions can be expanded flexibly , Easy integration with third parties , Meet more advanced business needs .
