native_handle_type是连接 std::thread 和操作系统线程库之间的桥梁,在 g++(libstdc++) for Linux 里面,native_handle_type 其实就是 pthread 里面的 pthread_t 类型,当 std::thread 类的功能不能满足我们的要求的时候(比如改变某个线程的优先级),可以通过 std::thread 类实例的 native_handle() 返回值作为参...
1.在声明一个std::thread 对象之后,都可以使用detach和join函数来启动被调线程,区别在于二者是否阻塞主调线程
pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED);//设置线程分离属性//文件处理线程if(0!= pthread_create(&file_tid, &attr, demux, (void*)filename))printf("create file handler thread failed!\n");//视频解码线程if(0!= pthread_create(&dec_tid, &attr, video_decoder,NULL))printf(...
std::thread ThreadStreame(VideoStream); std::thread ThreadCapture(VideoCapture); while(1); g_main_loop_quit(loopVideoCapture); g_main_loop_quit(loopVideoStream); ThreadStreame.join(); ThreadCapture.join(); return true; } to view this udp stream we can use following pipeline ...

首先opencv在gstreamer是有plugin的, 但是从应用开发的角度, 这样不够flexible :plugin里的东西和外界是封闭的. 在实现上, 更建议使用Appsink和AppSrc, 这些模块, 在你的应用里,是以Thread的形式存在的, 开发起来要更方便. 另外还有一点很重要, 就是什么gstreamer, gobject, 其实挺难用, 用C++会舒服很多。
