Icecast Restreaming and AAC Transcoding
Hello,
i am new the wowza and got simple Icecast MP3 Restreaming to work quite easily ;)
I can listen to different icecast streams now via Flash Player, VLC (rtsp) and iOS.
But i can't get the transcoding to work ;(
My Application.xml based on the wowza tutorials and suggestions:
My audioonly template:Code:<Root> <Application> <!-- Uncomment to set application level timeout values <ApplicationTimeout>60000</ApplicationTimeout> <PingTimeout>12000</PingTimeout> <ValidationFrequency>8000</ValidationFrequency> <MaximumPendingWriteBytes>0</MaximumPendingWriteBytes> <MaximumSetBufferTime>60000</MaximumSetBufferTime> <MaximumStorageDirDepth>25</MaximumStorageDirDepth> --> <Connections> <AutoAccept>true</AutoAccept> <AllowDomains></AllowDomains> </Connections> <!-- StorageDir path variables ${com.wowza.wms.AppHome} - Application home directory ${com.wowza.wms.ConfigHome} - Configuration home directory ${com.wowza.wms.context.VHost} - Virtual host name ${com.wowza.wms.context.VHostConfigHome} - Virtual host config directory ${com.wowza.wms.context.Application} - Application name ${com.wowza.wms.context.ApplicationInstance} - Application instance name --> <Streams> <StreamType>live</StreamType> <StorageDir>${com.wowza.wms.context.VHostConfigHome}/content</StorageDir> <KeyDir>${com.wowza.wms.context.VHostConfigHome}/keys</KeyDir> <!-- LiveStreamPacketizers (separate with commas): cupertinostreamingpacketizer, smoothstreamingpacketizer, sanjosestreamingpacketizer, cupertinostreamingrepeater, smoothstreamingrepeater, sanjosestreamingrepeater --> <LiveStreamPacketizers>cupertinostreamingpacketizer,smoothstreamingpacketizer,sanjosestreamingpacketizer</LiveStreamPacketizers> <!-- Properties defined here will override any properties defined in conf/Streams.xml for any streams types loaded by this application --> <Properties> </Properties> </Streams> <Transcoder> <!-- To turn on transcoder set to: transcoder --> <LiveStreamTranscoder>transcoder</LiveStreamTranscoder> <!-- [templatename].xml or ${SourceStreamName}.xml --> <!-- <Templates>${SourceStreamName}.xml,transrate.xml</Templates> --> <!-- <Templates>${SourceStreamName}.xml,transcode.xml</Templates> --> <Templates>audioonly.xml</Templates> <ProfileDir>${com.wowza.wms.context.VHostConfigHome}/transcoder/profiles</ProfileDir> <TemplateDir>${com.wowza.wms.context.VHostConfigHome}/transcoder/templates</TemplateDir> <Properties> </Properties> </Transcoder> <DVR> <!-- As a single server or as an origin, use dvrstreamingpacketizer in LiveStreamPacketizers above --> <!-- Or, in an origin-edge configuration, edges use dvrstreamingrepeater in LiveStreamPacketizers above --> <!-- As an origin, also add dvrchunkstreaming to HTTPStreamers below --> <!-- To turn on DVR recording set Recorders to dvrrecorder.

The system is an Debian (still Lenny) 64bit running a Wowza 3.1.2 with java 1.6.0_26Code:<!-- Example template for audio only transcoding to AAC from any support audio codec --> <Root> <Transcode> <Encodes> <!-- Example Encode block for source, not required unless Member of StreamNameGroup. --> <Encode> <Enable>true</Enable> <Name>aac</Name> <StreamName>mp4:${SourceStreamName}_aac</StreamName> <Video> <!-- H.264, PassThru, Disable --> <Codec>Disable</Codec> <Bitrate>${SourceVideoBitrate}</Bitrate> <Parameters> </Parameters> </Video> <Audio> <!-- AAC, PassThru, Disable --> <Codec>AAC</Codec> <Bitrate>48000</Bitrate> <Parameters> </Parameters> </Audio> <Properties> </Properties> </Encode> </Encodes> <Decode> </Decode> <StreamNameGroups> </StreamNameGroups> <Properties> </Properties> </Transcode> </Root>
In the access.log the following lines are listed:
Listening to ***.stream works well, but listening to mp4:***.stream_aac plays no music at all and from time to time some rubbish (like extreme fast forwarding) can be heard.Code:JNI:TranscoderSession.audioDecoderCreate[_defaultVHost_:live/_definst_/***.stream]: Create audio decoder: MP3: default transcoder INFO 200 ***.stream {codec:MP3, objectType:MPEG1LAYER3, sampleRate:44100, channels:2} JNI:TranscoderSession.audioEncoderAdd[_defaultVHost_:live/_definst_/***.stream:aac]: Create audio encoder: AAC: default JNI:AudioEncoderAAC.initialize[_defaultVHost_:live/_definst_/***.stream:aac]: channels:2 sampleRate:44100 bitRate:48000
What do i miss? Any ideas?
