Hi Rene,

I see, thank you for explaining!

Let me know if I can test or do something.

Have a good day

Hi Joop,

The timestamp that is given to each frame is taken from the function now(). See rtsp_server.cpp in the function:
bool rtsp_server::client_handler(void *arg)

auto now = millis();
	for (const auto &client : self->clients_)
	{
		// Handle requests
		client->session->handleRequests(0);
		// Send the frame. For now return the uptime as time marker, currMs
		client->session->broadcastCurrentFrame(now);
	}

This is only an uint32 and as this is in milliseconds, an absolute time is not possible. In the streamer some more magic is going on:

uint32_t units = 90000; // Hz per RFC 2435
  m_Timestamp += (units * deltams / 1000);                             // fixed timestamp increment for a frame rate of 25fps

It might be possible to change the timestamp here but this is in another library I do not own...

Perfect! Just what I needed! Thank you sir!
