When the server responds (second handshake), the initiator acknowledges it (third handshake) and a reliable connection is established.Īlso known as video contribution where a RTMP stream is used to send video between an encoder and server. Here’s how: the initiator asks the server to start a connection (first handshake). The RTMP stream sits on top of TCP where a three-way handshake enables data transportation.
RTMP uses transmission control protocol (TCP) which facilitates the exchange of data between devices in a network. These are sent independently via several virtual channels defined by the streaming protocol, which explains what makes RTMP live streaming efficient. In the case of network issues, it can quickly lose data over a few seconds, which can disrupt the stream.Ī RTMP stream works by chopping the data into smaller fragments of audio and video known as packets. RTMP live streaming is vulnerable to data loss.What’s more, certain networks block the RTMP port by default, which requires special firewall modifications to allow passage to the blocked network. RTMP live stream is no longer accepted for iOS, Android, most embedded players, and several browsers.It doesn’t support high-resolution video and video compression methods like VP9, AV1, and more.As an example, Vimeo uses RTMPS as the default protocol for Livestream Studio to make it easier and safer to stream. For organizations looking for a secure way to live stream internally for all-hands meetings or town halls, RTMPS is paramount.
RTMPS is a secure form of RTMP that minimizes the risks of cloud-based streaming.
