实际运行：mutex递归

• 【Fargo】5：根据网络带宽动态调整发送速率 需要外部动态改变码率的设定，以此影响包的发送间隔：

Exception thrown at 0x76A7B282 in HaloAppPublisher.exe: Microsoft C++ exception: std::system_error at memory location 0x003EEC48.
Unhandled exception at 0x76A7B282 in HaloAppPublisher.exe: Microsoft C++ exception: std::system_error at memory location 0x003EEC48. 这个mutex的异常是 // 将比特率降低到 4 Mbps
uint32_t reduced_bitrate = 4 * 1000 * 1000; // 4 Mbps
sender.set_target_bitrate(reduced_bitrate); 执行引起
