Expected Behavior

OBS Studio can reply the server's ping request to let server calculate the rtt between obs and server.

Current Behavior

OBS Studio just ignore all requests from server during publishing.

Steps to Reproduce

Just publish any stream to remote rtmp server.

Anything else we should know?

I noticed that in the plugins/obs-outputs/rtmp-stream.c, the function process_recv_data() just ignores all packets. Why?

static bool process_recv_data(struct rtmp_stream *stream, size_t size)
{
	UNUSED_PARAMETER(size);

	RTMP *rtmp = &stream->rtmp;
	RTMPPacket packet = {0};

	if (!RTMP_ReadPacket(rtmp, &packet)) {
#ifdef _WIN32
		int error = WSAGetLastError();
#else
		int error = errno;
#endif
		do_log(LOG_ERROR, "RTMP_ReadPacket error: %d", error);
		return false;
	}

	if (packet.m_body) {
		/* do processing here */
		RTMPPacket_Free(&packet);
	}
	return true;
}

Start in plugins/obs-outputs/rtmp-stream.c at process_recv_data(), then review the linked OBS log and the RTMP publishing path. Reproduce by publishing to a remote RTMP server and inspect how incoming packets are handled. Done means OBS responds to the server's ping request so the server can calculate RTT.
