Wowza Streaming Engine Messaging

server ERROR 500 - server core failed: java.net.BindException: address already in usevhost WARN 200 _defaultVHost_ Bind failed, try again ([any]: 1935): java.net.BindException: address already in use

Why:This is usually because another instance of Wowza Streaming Engine is already running. Shut down all instances of Wowza Streaming Engine and reboot. Wowza Streaming Engine can run as a service, in standalone mode, or within the Wowza IDE, but only one at a time.

feedback server ERROR 500: failed to connect: org.apache.mina.common.RuntimeIOException: failed to get session [ConnectException: connection refused].feedback server WARNING 200: RTPSessionDescriptionDataProviderBasic.getStreamInfo: RTSP/RTP relay . Cannot connect to server: rtsp://[wowza-ip-address]/myStream.sdp

Why:Try to connect to the IP camera with incorrect credentials.

WARN comment server 200 - RTPPacket.write: bad packet: incomplete NAL units.

Why:Packet loss in most cases. Try turning on packet loss logging to see if this is the problem. To seeEnable RTP jitter buffering and packet loss logging (RTP and MPEG-TS) on Wowza Streaming Engine.

feedback server ERROR 500 RTPDePacketizerMPEG4LATM.handleRTPPacket: Invalid packet length: 200:105

Why:This indicates a network connection problem. Try streaming the same file on your local host or on your local network to rule out network issues as a problem.

ERROR HTTPUtils.HTTPRequestToByteArray server comment: java.io.FileNotFoundException: http://[ip-address]/latest/meta-data/product-codesWARN Server comment Server.run: license key specified in [install directory] /conf/ The server.license file is in the wrong format. ERROR Server Comment Error: java.lang.NullPointerExceptionERROR Server Comment ERROR: Cannot write to license key file:

Why:This error is caused by using the wrong license key.

ERROR: Invalid license key or license file does not exist and is running as a service (exiting)

Why:This error is the result of using a perpetual license key for Transcoder, nDVR, or DRM without a valid perpetual license for the server.

Server ERROR Comment: Wowza Media Systems Software Licensing has determined that your serial number is invalid. Make sure you are using the correct serial number. If the problem persists, please visit http://www.wowza.com/subscriptionsupport.php for updated information. ERROR Server comment: system.exit

Why:This error is due to an unpaid subscription. ContactCustomer Supportresolver.

comentario servidor ERROR PushPublisherRTMP: com.wowza.wms.server.LicensingException: Server.license

Why:This error can be seen when using an older Amazon EC2 AMI in conjunction with the autopublishing API. Wowza Streaming Engine works as expected locally or in test, but the deployment server throws this license error. That specific license restriction has since been lifted. Upgrading to a current AMI resolves this issue.

servidor de comentario ERRO 500 - invocar(onHTTPCupertinoStreamingSessionDestroy): java.lang.NullPointerException: com.ptin.wms.module.AbortSession.onHTTPCupertinoStreamingSessionDestroy(EndSession.java:10)

Why:In this example, there is an error in the custom module named AbortSession on line 10. The custom module developer should resolve the issue.

WARN 200 application folder is missing from the feedback server ([install location]/applications/_defapp_)

Why:This error is generated when you connect to Wowza Streaming Engine without the application name.

Feedback server WARN 200 - Missing application folder ([install location]/applications/:80)

Why:Usually this is because FFmpeg is being used as an encoder and is not sending the application name correctly.

Why:This MediaCaster problem is usually caused by some kind of network error. For example, the SHOUTcast server is not enabled. Here we see the start of a live stream and then warnings and errors indicating that the Wowza Streaming Engine has encountered a dependency fault.

ERROR server comment RTPSessionDescriptionDataProviderBasicRTSPConnection.connect[wowza-ip-address]:[port-number]: Could not connect: org.apache.mina.common.RuntimeIOException: Could not get session[ConnectException: Connection refused: no further information]. WARN server comment LiveMediaStreamReceiver.doWatchdog: streamTimeout: Connection reset

Why:Wowza Streaming Engine cannot connect to a MediaCaster stream. It could be a problem with the network or with the source. For example, the camera was reached but it refused the connection. Wowza Streaming Engine will keep trying to reconnect until the stream is available again.

Why:2-4 bind lines, quickly followed by 2-4 unbind lines, indicates UDP session failure, ports blocked. Usually the problem is in the firewall of the computer where Wowza Streaming Engine is installed. It can also be the router, the proxy in the environment or the operator network in the RTSP streaming app.

RTPDePacketizerWrapperPacketSorter.handleRTPPacket["+contextStr+":"+rtpTrack.getTrackId()+"]: The stream is MPEG-TS, which is not supported by the packet classifier. The packages will be forwarded.

Why:The packet classifier forwards MPEG-TS packets and reports this to the registry. The part in parentheses is theappName/appInstanceNAME/streamName:trackname.

Error parsing VHosts.xml (file:///usr/local/WowzaStreamingEngine/conf/VHosts.xml): java.util.ArrayList cannot be cast to org.w3c.dom.NodeListException on java "main" thread. lang .NoClassDefFoundError : com.wowza.wms.server.Server on java.lang.Class.initializeClass(libgcj.so.7rh)

Why:These messages appear when trying to start Wowza Streaming Engine. "libgcj.so" indicates that it is an old version of Java that may have been part of a Linux distribution. Install the latest Oracle Java software and verify that it is installed correctly before restarting Wowza Streaming Engine.

server WARN 404 [path to video file] MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: missing atom file 'moov'.

WARN server comment MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: Invalid atom size: 0.

Why:Occurs when trying to play a file that is not an MP4 file. This error is thrown by the MP4 file parser, indicating that it cannot find the information it expects. Usually the problem is that the wrong prefix is ​​being used.

ERROR server comment QTWriterUtils.loadForAppend[path to video file][index]: Incorrect atom length: -8WARN server comment QTWriterUtils.loadForAppend[path to video file][index]: MOOV Atom is missing Server comment server WARN QTWriterUtils .loadForAppendParseMOOV[path to video file]: WARNING: Add: atom 'stsc' contains incorrect sample count information: missingSampleCount:26 lastChunkCount:1 lastSamplesPerChunk:25 totalSampleCount:79926 samplesAccountedFor:79900

Why:When recording a video, if the file is moved before the recording is complete (not posted), the file cannot be played and you will see the missing moov atom error. When the stream is not published, Wowza Streaming Engine writes the moov atom data to the end of the file. The resulting script would have a problem if there was a problem with the unpublish mechanism, for example if the server crashed or unpublish was not triggered for some reason.

ERROR Server Comment QTWriterUtils.loadForAppend[path to video file][index]: Incorrect atom length: -8WARN Server Comment QTWriterUtils.loadForAppend[path to video file][index]: Missing MDAT Atom

Why:Caused by writing the file. For example, a problem writing to the destination filename specified for recorded video could cause this error. mdat atom is a required top-level atom.

WARN server comment MediaReaderFLV.open: Metadata appears to be incorrect: [stream-name]

Comment from server error MediaReaderFactory.getInstance: Missing definition for mov

Why:Try to play a file with the .mov prefix when the file is not of this type of transmission.

Why:This is a file structure related error. Try other files or ourdemo filesto determine if it is file specific. Please provide your live stream or VOD file to Support for further review.

Access Forbidden (403)

Why:This error is seen in an encoder trying to connect to Wowza's streaming engine. It is not registered in the Wowza records. This can be caused by specifying a Wowza application that is not configured on Wowza Streaming Engine. It can also be caused by trying to play Wowza Streaming Engine files as if it were a web server, which will not work. The sample.htmlfiles must be opened directly in a web browser.

Feedback server WARN 404 mpegts.stream MediaReaderH264.open[1]: java.io.FileNotFoundException: C:\Program Files (x86)\Wowza Media Systems\Wowza Streaming Engine [version]\content\mpegts.stream (The system may 't find the specified file)

Why:Occurs when the sequence cannot be found. Common causes are that theFlows/Flow Typeis not configured correctly inApplication.xmlor the stream is starting with the StreamManager and the wrong MediaCaster type was selected when starting the stream.

feedback server ERROR Please close the RTSP/RTP session. Session timeout: 90000

Why:Timeout limit exceeded. The value can be set toRTP/RTSPSessionTimeoutno[install directory]/conf/[application name]/Application.xml🇧🇷 The value is in milliseconds. Defined as0to never expire. For problematic MediaCaster streams, seeMonitor and restore streams from Wowza Streaming Engine MediaCaster.

Why:This message appears when the application name or URL is invalid. If you use the sample players, a common cause is that the app name differs from the default app name by default. Check the URL.

WARN 200 HTTPStreamerAdapterCupertinoStreamer.service server comment: request timeout: 12000

Why:There are no flow connections within the timeout value. Check your live source and encoder.

WARN 200 RTPPacketFragmentListReader.skip: Incorrect number of hops: -123456789

Why:This indicates packet loss or an incomplete packet. This message can appear when the CPU or GPU utilization for acceleration is at or beyond a feasible threshold, or if there is a lot of network traffic. Make sure Wowza Streaming Engine is tuned by following the instructions onTune Wowza Streaming Engine for optimal performance.

ERRO 500 - addDataA[this.size:248620 this.dataA.length:248620 this.startDataLoc:278333 this.dataLoc:278333 data.length:4016 offset:152 size:32 falta:22 ]: java.lang.ArrayIndexOutOfBoundsException

Why:The correct amount of data for the incoming packet is not present. This message can appear when CPU or GPU utilization for acceleration is at full capacity or exceeds a workable threshold, or when there is heavy network traffic. Make sure Wowza Streaming Engine is tuned by following the instructions onTune Wowza Streaming Engine for optimal performance🇧🇷 Packet loss can occur when CPU/GPU utilization or network performance is maxed out.

WARN 200 - RTPDePacketizerWrapperPacketSorter.handleRTPPacket[:mpegts]: The stream is MPEG-TS, which is not supported by the packet classifier. The packages will be forwarded.

Why:Remove the package sorter from yourApplication.xmlsettings if it does not apply to your stream.

Server ERROR 403 ModuleRTMPAuthenticate.checkSecureToken: Action before receiving response: close connection:

Why:A client tries to connect without responding to the secure token request. Make sure the code is correctly embedded in the player.

DirectRandomAccessReader.read: java.io.IOException: The specified network name is no longer available

Why:Network related error. check if thestorage addressproperty in[install directory]/conf/[application name]/Application.xmlpoints to an available mapped drive or UNC path.

ERROR 500 - Server kernel failed: java.lang.NullPointerException

Why:Possible corrupt installation. Try reinstalling Wowza Streaming Engine.

ERROR server comment Could not connect: org.apache.mina.common.RuntimeIOException: Could not get session [ConnectException: Connection timed out: no more information] ERROR server comment RTPSessionDescriptionDataProviderBasic.getStreamInfo: Timeout for RTSP/RTP streaming.

Why:Both errors are related to network connectivity issues, the inability to connect to the MediaCaster stream. Look at the log lines above for clues. This can also be due to the upper limit being reached on the number of streams the server can handle. It may be necessary to add another server. I recommend configuringMediaCaster Stream Monitor, which monitors and restores bad streams and server monitoring with JConsole.

ERROR server comment RTPMulticastListener.unbind:java.net.SocketException: configuration options error

Why:Usually caused by network connectivity issues.

ERROR server comment packageSizeReset: 12:345 ERROR server comment Zero size function (client): type: 20 size: 0 index: 123 ERROR server comment Incorrect data format, dropping client connection.

Why:This can be caused by many factors, but is usually caused by a TCP error or a communication error. It usually indicates that Wowza Streaming Engine is overloaded in some way: CPU, I/O, network, or even the GC is running for too long. To seeTune Wowza Streaming Engine for optimal performancefor information on changing GC options and other areas to check.

Why:Typical causes for a connection to a SHOUTcast/Icecast stream to fail are:

• The doors are locked. Make sure the ports are not blocked or conflicting with another application.
• The SHOUTcast/Icecast server is offline, so the connection and retries fail.
• Incorrect URL. To seeURL to connect to SHOUTcast or Icecast🇧🇷 You must use the media url, not the playlist url.
• If this is an intermittent issue, the SHOUTcast/Icecast stream may be choppy and inconsistently available.

WARN Server Comment - RTPDePacketizerMPEGTS.handleRTPPacket: out of sync: 0x[nn]

Why:This could be due to two encoders sending a stream to the same port. It may also be that the flow is not aligned. Install the latest version of Wowza Streaming Engine and try to configure thempegtsVideoIsAlignedproperty forfalseas described inFix missing or junk video (MPEG-TS) in Wowza Streaming Engine.

Alternatively, the MPEG-TS encoder may not be correctly aligning TS packets into UDP packets. Add the following property toRTP Container/Propertiesno[installation-dir]/conf/[application]/Application.xml(make sure you get the correct<Properties>container; there are several in the file):

<Property> <Name>rtpDePacketizerWrapper</Name> <Value>com.wowza.wms.rtp.depacketizer.RTPDePacketizerWrapperReChunkMPEGTS</Value></Property>

Wowza's drive motor only allows for a singlertpDePacketizerWrapperworth. If you have configured a jitter buffer or a packet logger that uses the samertpDePacketizerWrapper, they must be removed.

WARN server comment - RTPDePacketizerBase.checkRTCPSSRC: ssrc error: e8b92a:6319b7c8

Why:This usually means that the encoder has been started and stopped and the session has not timed out. When that happens, thessrcchanges in ownership of RTP packets. Wowza Streaming Engine blocks incoming packets because this value has changed. There is a 12 second transmission timeout set for RTP transmissions. As long as the encoder is idle for more than 12 seconds, the stream should restart and be fine.

feedback server WARN 200 - Waiting for RTCP packet. See the docs for (Application.xml: RTP/AVSyncMethod and RTP/MaxRTCPWaitTime).

server feedback INFO 200 - Server.startShutdownHook: start server shutdown hook

Why:This log line is part of the standard Wowza Streaming Engine start lines. The boot line is nothing to worry about. Additional logging can help troubleshoot shutdown issues.

WARN server comment - HTTPStreamerAdapterCupertinoStreamer.onEncKey[myApplication/_definst_/myStream/key_w1063299536.m3u8key]: onEncKey is not enabled.

Why:This notice indicates thatonEncKeydelivery is not enabled onHTTP Transmitter/PropertiesnoApplication.xml🇧🇷 It is disabled by default for security reasons.

Why:Any module method can cause this error, and the name of the method is provided in the first part of the message:get together(moduleMethodName)🇧🇷 The error occurs when a module method throws an exception that is not caught or handled in the method. The exception is thrown for built-in controllers that call the module's methods.

Uncaught exceptions can cause memory leaks or make Wowza Streaming Engine unstable because instructions that normally occur after the exception occurs will not be executed.

To find the nature of the error:

1. Capture and log the original error to see what is causing it. The following example shows how to detect and log the error. The error message will move fromget togethermethod for themodulemethod.

Why:This type of registration error indicates an audio/video alignment problem. Due to this alignment problem, the blocks are not written and the recording is degraded. The best way to fix this is upstream from Wowza nDVR (usually in the encoding process). While it is strongly recommended that you correct any audio/video alignment issues before recording, there are nDVR properties that you can configure inApplication.xmlto try to compensate for this problem. Note that these properties do not fix the alignment issue, but they may help to fix it. To seedvrPacketSortTimemidvrAllowableAVPacketDelta.

messages to transcoder

WARN Server Comment TranscoderWorkerVideoDecoder.handlePacketVideo[_defaultVHost_:AppName/_definst_/StreamName: decodeIterations:565]: Video decoder pending frame count[198] is greater than threshold[150], restarting

Why:The transcoder cannot decode the stream fast enough. This is usually due to a lack of CPU or GPU resources, but it can also be related to font encoding.

WARN Server Comment LiveStreamTranscoder.isTranscoderAvailable: Transcoder is not available for your platform: platform: null architecture: 32

Why:The transcoder requires a 64-bit platform. This warning occurs if Wowza Streaming Engine is not installed on a 64-bit operating system or if you have an older version of Java installed on your computer. To resolve the Java version issue, seeInstall and troubleshoot Java manually on Wowza Streaming Engine.

JNI WARN Server Comment:AudioEncoderAAC.initialize[_defaultVHost_:myApplication/_definst_/myStream:360p]: Bit rate too high for sample rate. Bit rate adjusted from 128,000 to 48,000

Why:The input sample rate is too low to support the selected bit rate for transcoding. If the input sample rate is 22.05 KHz, 24 KHz, or 32 KHz, you are restricted to a 48 Kbps audio stream. Try using a 44.1 KHz sample rate in the source stream being ingested , or lower the audio bitrate in the encoding preset by adjusting the transcode template.

Comentario del servidor WARN ApplicationInstance.setLiveStreamTranscoderList[myApplication/_definst_]: LiveStreamTranscoder no es válido: transcoder

Why:The transcoder did not start correctly and there are other errors in the registry that indicate a faulty installation or permissions issue. Before reinstalling make a backup[install directory]\conffiles for reference when reconfiguring. Another cause could be that "transcoder" is misspelled[install directory]\conf\[application name]\Application.xml🇧🇷 Take a good look at the last word of the message.

Why:The expected data stream is not being sent to the Wowza Streaming Engine. Check the input source.

Comentario del servidor WARN HTTPStreamerCupertinoIndexPlaylist.indexFile[myApplication/_definst_/ngrp:myStream_all]: MediaList está vacío.

Why:There are several causes that can generate this error:

• Malformed URL or an error in the transcoder template. Check that the value of<Group of Stream Names>/<Stream Name>(no<Group of stream names>/<Name>), is specified as the broadcast group name in the URL. In this example, the name of the source stream ismy streamand the problem is that the value of<Group of Stream Names>/<Stream Name>It is not${SourceStreamName}_all.
  
• o<Encode>/<Name>It's in<Sequence Name Group>/<Members>/<Member>/<Encoding Name>are not the same In the sample template, you will see the coding block<Name>360p</Name>has a matching sequence name group block member name (<EncodeName>360p</EncodeName>).
  
• The transcoder model that was loaded was not as expected, so the stream name specified in the URL is incorrect. Wowza's drive motor uses the first model listed onTranscoder/ModelsnoApplication.xml🇧🇷 Review the log to validate the model name being loaded.
• Other errors that indicate a problem with the resulting stream, such as no audio.

Why:The source has no audio.

WARN 200 - TranscoderStreamNameGroup.addInternal[myApplication/_definst_/myStream]: namegroup in aggregate, is empty: myStream_all

Why:The stream name group was not created because the transcoder cannot transcode the stream. Make sure the source stream uses supported codecs (seeSupported video and audio formats🇧🇷 Also, make sure theEnableproperty value for all<Encode>the blocks in the model file are defined asreal.
