I have a single encoder broadcasting a single high quality (10 Mbps) RTMP-stream.

Now, I want Wowza to take this incoming stream and serve three Flash streams (2 Mbps, 1 Mbps and 400 Kbps) as well as three iOS streams (1,5 Mbps, 800 Kbps and 128 Kbps).

How do I set up my Wowza server to make these six streams from the single incoming stream?

You can use the Wowza Transcoder:

There are benchmark results for reference here:

Right, per your edit, you also need 64bit Java and JAVA\_HOME must point to it

I don’t know, I don’t have experience with that. Try installing on the Mac OS.

Thank you, that was what I needed.

However I get this error:

```auto
WARN server comment - LiveStreamTranscoder.isTranscoderAvailable: Transcoder is not available for your platform: platform:win architecture:32

```

I’m running Wowza on **Windows 7 x64** through Parallels (OSX 10.7)

**Edit:** I found what I believe could be the answer in a reply to another thread:

> You also have to have a 64bit version of Java JDK, and your JAVA\_HOME system variable has to point to it.

When trying to install the jdk-7u9-windows-x64.exe I get the strangest of errors:

_… is not a valid 32 bit application._

I’m running Windows 7 x64 so why do I get this eror? Is it because I’m running Windows through Parallels (OSX 10.7)?

Even if Wowza Transcoder Hardware and Driver Requirements states:

_Note: 32-bit operating systems are not supported and **OSX is not supported.** _

**Edit:** The requirements are correct unfortunately, I get this under OSX 10.7:

```auto
WARN server comment - LiveStreamTranscoder.isTranscoderAvailable: Transcoder is not available for your platform: platform:osx architecture:64

```
