You can use the Wowza Streaming Engine™ Java API to control which streams get transcoded.
Below is a simple module that uses the ILiveStreamTranscoderControl interface to control which streams get transcoded:
package com.wowza.wms.plugin.test.module;
import com.wowza.wms.stream.*;
import com.wowza.wms.stream.livetranscoder.*;
import com.wowza.wms.module.*;
import com.wowza.wms.application.*;
public class ModuleTranscoderControlByStream extends ModuleBase
{
class TranscoderControl implements ILiveStreamTranscoderControl
{
public boolean isLiveStreamTranscode(String transcoder, IMediaStream stream)
{
// here is there you return true or false if you want stream transcoded
if ( stream.isTranscodeResult() )
{
return false;
} else {
return true;
}
}
}
public void onAppStart(IApplicationInstance appInstance)
{
appInstance.setLiveStreamTranscoderControl(new TranscoderControl());
}
}
To add this module to your application, edit [install-dir]/conf/[application]/Application.xml and add this module entry as the last <Module> entry in the <Modules> list:
<Module> <Name>ModuleTranscoderControlByStream</Name> <Description>ModuleTranscoderControlByStream</Description> <Class>com.wowza.wms.plugin.test.module.ModuleTranscoderControlByStream</Class> </Module>
