Here is a simple list of comparison for WebRTC vs. RTMP

Here is a simple list of comparison for WebRTC vs. RTMP

RTMP is old technology. WebRTC is the newer technology.
Browser does not support RTMP which requires flash plugin to playback(so that it does not work on mobile at all). WebRTC is supported natively by browsers. No need to have any plugin.
RTMP latency is about 2–3 secs. WebRTC latency is less than 1 secs.
WebRTC is more complex than RTMP
There is a migration from RTMP solutions to WebRTC solutions.
There are solutions in the internet that supports RTMP, WebRTC as well. Here is a list of the items like Red5Pro, Wowza, Ant Media Server, Jitsi, etc.

The main value offered by RTMP is that throughout the streaming process a connection is maintained between the streaming server and the video player. This ensures smooth video streaming in spite of any fluctuations in bandwidth.

RTMP uses port 1935. The key differentiator between RTMP and Progressive Streaming services using HTTP is:

In RTMP there is a direct pointer from media server to flash player, and only data corresponding to that pointer is held by the flash player. There is no buffering/ storage of data on the computer
In progressive streaming a steady buffer is created, starting from point of playback

RTMP peaked in its popularity around 2012. Since then with the emergence of adaptive bitrate streaming, HTTP based streaming protocols have become much more popular. In adaptive bitrate streaming, each video stream comprises of multiple files at different resolutions which require different bitrates. A video player is sent the streaming file corresponding to its screen size and internet connection speed. This process ensures that if a viewer is initially viewing a high quality stream initially at high bandwidth, if the internet speed drops the video player would immediately switch to a lower resolution stream. One of the HTTP based protocols that does this efficiently is Apple’s video streaming protocol HLS.

Where RTMP server maintains a constant connection between media server and video player, progressive video players on HTTP rely on a buffer. This means that the video is initially downloaded, and it is this locally cached file that is played back. HTTP relies on this buffer to ensure smooth playback. However if the buffer load rate is slower than the playback rate then your stream will lag.

From point of view of security, RTMP Encrypted is somewhat flawed, as it is prone to Man-in-the-Middle Attacks. RTMP toolkit – RTMPDump can be used easily to download RTMP streams.

Hope this helps. For more info do check out this article that I’ve written on RTMP in relation to other streaming protocols.

Media servers red5 and wowza

Red5 is a media server created with Java language. It is a free open source software but recently a new version Red5 Pro came out developed by the same people, this new version supports streaming to mobiles, Android or iOS, which red5 does not. The Red5 Pro is commercial product and costs $55 per server.

A media server allows Flash based applications connect to it using Real Time Messaging Protocol (RTMP). The server can send and receive data to and from the connected users who have a flash player installed. The server also allows users to receive and publish streams. This permits video chat applications, live streaming and even ondemand video streaming.

Most common Video chat software’s are:
1- Avchat
2- Videowhisper
3- Prochatrooms
4- Gchats

For live streaming the necessary tool if you already have a server with red5 installed is an encoder, an encoder is the software that will connect your computer to the red5 server using the RTMP, which your server provider will give you.
1- FMLE, it is an free Adobe product and does a good job.
2- Wirecast, it is an expensive commercial product of very high quality, absolutely necessary if you starting a TV station.

Although red5 is a free product many people prefer to use Wowza Streaming Engine or Adobe Flash Media Server which are commercial software’s and can be quite expensive, the FMS costs $4500 per server. The reason is that the developers of red5 although have created a wonderful system did not spend much time with tutorials and instructions on how to install and manage a red5 server, for this reason if you searching for a red5 server we suggest you pick a web host which specializes on red5 servers and red5 shared hosting.

1- Red5 Servers relatively cheap red5 servers starting at $15 a month.
2- Red5 Hosting, Hosting Marketers, a web host for experienced webmasters, it is the oldest hosting company specialized on Video and media servers, they also offer Wowza Streaming Engine on its shared plans. They have a very experienced customer support and a reputation for going out of their way to help customers. They starting plan with Red5 enabled costs $9.95 a month. Most other red5 hosting companies are resellers of Hosting Marketers.

Red5 is a formidable media server, extremely flexible and has the advantage of being a free product with with many people working on developing it, for now the main version does not yet work with mobiles, if that is what you need we suggest that instead of using the Red5 Pro version to use the Wowza instead.

This was related to the web servers. There are several internet web servers and hosts working today. The previous generation of the web servers allowed only fewer connections, less space and availability on the computer only.
