while (run_flag) {
                DecFrame *frame = mpp_dec->ops->dequeue_timeout(mpp_dec, 300);
                std::cout<<"!!!!!!!!!!!!!!!"<<endl;
                if (frame != NULL) {
                        std::cout << "decode frame" << frame->width << "x" << frame->height << std::endl;
               
                        if (!first_frame) {
                                std::cout << "first_frame" << std::endl;
                                t_inference = std::thread(inference_thread, rga, frame->width, frame->height);
                                first_frame = 1;
                        }
frame 这里一直为空，是什么原因？用ffplay能够在板子上打开视频流

在RK1808M0上运行sudo ./rtsp_ssd时报错:
用vlc可以打开流地址,如何解决问题

你好，你这个怎么解决的，我也遇到这个问题

yuys 发表于 2020-10-29 18:39
用网桥模式。

一般不是网络的问题导致的，demo的RTSPClient兼容性很差，也不知道内部如何组包取帧的，打算自己写rstp组包的部分

loveltyoic 发表于 2021-5-10 18:16
你好，遇到了同样的错误。
我后来换了一个流，可以正常解码。我怀疑是有些流解不了码 ...

是帧取不到导致的，看图还没走到解码部分

有没有多路同时解码的案例？

1808板子可用用这个库么？

这个是解码流程，有没有用MppEncoderCreate这套接口编码的示例代码呢

TB-RK3399pro debain10系统如何进行环境安装和系统软件包的安装呢？
