wowza media server 2, restreaming from IP cam over RTSP (interleaved mode). playing by VLC, video is good but no audio (AAC), wowza logs: ```auto INFO server comment - RTPMediaCaster.Reconnector[4171469:live.interleaved/_definst_:103.stream]: done: 1 INFO server comment - senderReport[RTP-Info]: trackID=0 INFO server comment - senderReport[RTP-Info]: trackID=1 INFO server comment - firstPacket: TCP:$0 INFO server comment - firstPacket: TCP:$2 INFO server comment - LiveStreamPacketizerSanJose.init[live.interleaved/_definst_/103.stream]: chunkDurationTarget: 10000 INFO server comment - LiveStreamPacketizerSanJose.init[live.interleaved/_definst_/103.stream]: chunkDurationTolerance: 500 INFO server comment - LiveStreamPacketizerSanJose.init[live.interleaved/_definst_/103.stream]: playlistChunkCount:4 INFO server comment - MediaStreamMap.getLiveStreamPacketizer: Create live stream packetizer: sanjosestreamingpacketizer:103 .stream INFO server comment - SanJosePacketHandler.startStream[live.interleaved/_definst_/103.stream] INFO server comment - LiveStreamPacketizerSanJose.handlePacket: Video codec: H264 INFO server comment - LiveStreamPacketizerSanJose.handlePacket: Audio codec: AAC INFO server comment - LiveStreamPacketizerCupertino.init[live.interleaved/_definst_/103.stream]: chunkDurationTarget: 10000 INFO server comment - LiveStreamPacketizerCupertino.init[live.interleaved/_definst_/103.stream]: chunkDurationTolerance: 50 0 INFO server comment - LiveStreamPacketizerCupertino.init[live.interleaved/_definst_/103.stream]: audioGroupCount: 3 INFO server comment - LiveStreamPacketizerCupertino.init[live.interleaved/_definst_/103.stream]: playlistChunkCount:3 INFO server comment - MediaStreamMap.getLiveStreamPacketizer: Create live stream packetizer: cupertinostreamingpacketizer:1 03.stream INFO server comment - CupertinoPacketHandler.startStream[live.interleaved/_definst_/103.stream] INFO server comment - LiveStreamPacketizerCupertino.handlePacket[live.interleaved/_definst_/103.stream]: Video codec:H264 i sCompatible:true INFO server comment - LiveStreamPacketizerCupertino.handlePacket[live.interleaved/_definst_/103.stream]: Audio codec:AAC is Compatible:true INFO server comment - LiveStreamPacketizerCupertino.handlePacket[live.interleaved/_definst_/103.stream][avc1.66.20]: H.264 Video info: {H264CodecConfigInfo: profile: "Baseline", level: 2.0, frameSize: 352x288, displaySize: 352x288} INFO server comment - MediaStreamMap.getLiveStreamPacketizer: Create live stream packetizer: smoothstreamingpacketizer:103. stream INFO server comment - LiveStreamPacketizerSmoothStreaming.startStream[live.interleaved/_definst_/103.stream] INFO server comment - LiveStreamPacketizerSmoothStreaming.handlePacket[live.interleaved/_definst_/103.stream]: Fragment dur ations: [4.0,4.0,4.0] INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[live.interleaved/_definst_/103.stream]: Add chunk: id:1 a/v/ k:0/300/3 duration:11990 INFO server comment - LiveStreamPacketizerSanJose.endChunkTS[live.interleaved/_definst_/103.stream]: Add chunk: id:1 a/v/k: 0/301/3 duration:11990 INFO server comment - LiveStreamPacketizerSmoothStreaming.flushPendingVideo: Bitrate[live.interleaved/_definst_/103.stream] : 295056 ``` I see no problems with audio there: ```auto LiveStreamPacketizerCupertino.handlePacket[live.interleaved/_definst_/103.stream]: Audio codec:AAC is Compatible:true ``` VLC plays audio fine if receiving directly from IP cap what can be a problem? thank you ---

Does it play in Wowza example LiveVideoStreaming player: Server: rtmp://[wowza-address]:1935/live.interleaved Stream: 103.stream What does the VLV codec info show? Richard ---

Paulo, Are you playing the source in VLC? Or are you re-streaming and playing the Wowza stream in VLC? What does VLC report the audio codec as when you play the source in VLC? Richard ---

Paulo, The video and audio codecs for the upd stream look right. Are you following this guide? : [https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder](https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder)) Richard ---

I have the same problem. ```auto INFO server comment - LiveStreamPacketizerSanJose.handlePacket: Video codec: H264 INFO server comment - LiveStreamPacketizerSanJose.handlePacket: Audio codec: AAC ... INFO server comment - LiveStreamPacketizerCupertino.handlePacket[live/_definst_/teste.stream][mp4a.40.3]: AAC (Audio may not be playable on older iPhone and iPod touch devices where 48KHz/stereo or lower is required) Audio info: {AACFrame: size: 0, rate: 96000, channels: 4, samples: 1024, errorBitsAbsent: true, profileObjectType: "SBR"} ``` The original stream as audio and video but when i open wowza in vlc i only have the video (in codec details there is only one stream). What can i do ? Paulo ---
