See: http://ptrthomas.wordpress.com/2008/04/19/how-to-record-rtmp-flash-video-streams-using-red5

#### 2.2.4.4. Does Red5 support multicast streaming?

It should be noted that multicasting support is not available in the Flash Player. For that reason, no media server can deliver a multi-casting solution to the Flash Player. In addition, many networks have multicasting turned off so it may not be realiable for other platforms either such as Windows Media Player. These solutions usually fall back to unicasting when clients cannot receive muliticasted media. In regards to Unicasting, Red5 already has this functionality. In addition, we have an edge-origin solution sometimes referred to as stream-reapeating.

#### 2.2.4.5. Can Red5 stream using UDP?

No. Even though Java can stream using UDP, the Flash Player can not receive data sent using UDP.

### 2.2.5. Codecs

#### 2.2.5.1. What Codecs does Red5 Support?

Video codecs:

- ScreenVideo

- On2 VP6

- H264

Audio codecs:

- ADPCM

#### 2.2.5.2. What is RTMFP and when will it be available in Red5?

RTMFP stands for "RTMFP (Real Time Media Flow Protocol". You can read more about it in the release notes. Just search the following page.

To understand what this protocol is and does, read the following FAQ.

Red5 does not support RTMFP. At the moment, there isn't enough exposure to RTMFP and discussion can resume once it is released and more is known about the protocol.

### 2.2.6. Database

#### 2.2.6.1. What databases are supported?

Red5 is built with Java. So any database that has a JDBC driver will work.

#### 2.2.6.2. Can I use Hibernate with Red5?

### 2.2.7. Scripting

#### 2.2.7.1. What scripting languages are available?

Scripting support (JavaScript, Groovy, Beanshell, JRuby, Jython)

`issue: Closing RTMPMinaConnection from [IP_ADDRESS] : 2610 to [IP_ADDRESS] (in: 3415 out 3212 ), with id 512231886 due to long handshake`

solution: Have you installed the example your trying to connect to? The examples are installed on demand starting with Red5 0.8. Just check the welcome page http://localhost:5080/ and look for a link that allows you to install them. After an example is installed, you should be able to run the examples.

Note: We are improving this so that if an example is chosen, it will be installed.
