RTSP over TCP vs RTSP over UDP: Choosing the Right Transport
Understand RTP interleaving over TCP versus raw UDP datagrams for glitch-free security camera streams.
Need an active live RTSP stream to test this integration?
Generate a free 20-minute authenticated live H.264 video feed with frame counters to test in VLC, OpenCV, or NVR software.
#1Why RTSP over TCP is Preferred on Modern Networks
UDP drops packets under network congestion without retransmission, leading to macroblocking, grey smearing, and corrupted I-frames. RTSP over TCP interleaves RTP/RTCP data inside the existing TCP connection, guaranteeing in-order frame delivery through firewalls.
