There is a frame loss situation when using multiple channels

[gczhcm]

In the case of acquiring multiple video streams and one thread per path, there is a phenomenon of frame dropping. By capturing the packet, the machine has received the lost packet, but the program has not received it. Below is my code.
bool RtspClient::isPlay() { bool isplay=false; pthread_mutex_lock( &this->playMutex ); if(this->Del==0&&this->used==1) isplay=true; pthread_mutex_unlock( &this->playMutex ); return isplay; } uint32_t timesTamp=0; while( Client->isPlay()) { uint8_t* ret = Client->GetMediaData("video", buf, &size, bufSize,&timesTamp); }
I added the get rtp timestamp and found that there is a frame loss situation at 25fps. I use the way of RTSP over TCP to get data. I want to ask the function uint8_t * MyRTPTCPSession::GetMyRTPData(uint8_t * data_buf, size_t * size, unsigned long timeout_ms) whether it is multi-thread safe

Maybe you can refer to #6 to enlarge the rtp buffer.
By the way, MyRTPTCPSession::GetMyRTPData is not multi-thread safe.

how to set buf size of rtp with tcp

[gczhcm]

there is not tcp

I‘ll be appreciate if you can help me to capture the packets with wireshark and send it to [email protected] to give me more info to find the problem.
