I’m using VLC as transcoder and Wowza Server as streaming server. Wowza Server (Wowza Media Server 2 Developer 2.0.0 build22912) is configured as reported in [https://www.wowza.com/quickstart.html#live-mpeg-ts](https://www.wowza.com/quickstart.html#live-mpeg-ts) (see section All Player Technologies). The client talks with the server and negotiates a streaming connection like this one: Transport: MP2T/H2221/UDP;unicast; The client negotation works but unfortunately I don’t see any data sent from Wowza to the device. Here I explains my configuration: a) VLC is installed on Windows Machine (192.168.128.175) and it sends the Transcoded Stream (Extremists.m4v coming from Wowza sample files) to the Wowza server over udp://192.168.128.75:10000. I’m using VLM via telnet and the configuration is: > show show media : ( 1 broadcast - 0 vod ) flow type : broadcast enabled : yes loop : yes inputs 1 : C:\Documents and Settings\admin\Desktop\Extremists.m4v output : #transcode{vcodec=h264,vb=800,scale=1,acodec=mp4a,ab=128,channels=2,samplerate=44100}:std{access=udp,mux=ts,dst=192.168.128.75:10000}" options instances schedule > control flow play b) Wowza is installed on a Linux Machine (192.168.128.75). c) Sniffing with Wireshark I see the UDP traffic from 192.168.128.175:VLC to 192.168.128.75:Wowza to the port 10000 (as described in the Wowza Howto). So VLC send transcoded stream to Wowza. d) The Wowza Server Log is the following: INFO stream create - - INFO stream publish mpegts.stream - INFO server comment - HTTPStreamManager.onHTTPRequest: Publish stream successfully started [rtplive/_definst_]: mpegts.stream INFO server comment - RTPUDPTransport.bind: /0.0.0.0:10000 INFO server comment - UDPTransport.firstPacket: /0.0.0.0:10000 INFO server comment - RTPMediaCaster.Reconnector: stop INFO server comment - RTPDePacketizerMPEGTS.handleRTPPacket: audioPID: 0x44 INFO server comment - RTPDePacketizerMPEGTS.handleRTPPacket: videoPID: 0x45 INFO server comment - CupertinoPacketHandler.startStream[rtplive/_definst_/mpegts.stream] INFO server comment - LiveStreamPacketizerSmoothStreaming.startStream[rtplive/_definst_/mpegts.stream] INFO server comment - LiveStreamPacketizerCupertino.handlePacket: Audio codec: AAC INFO server comment - LiveStreamPacketizerCupertino.handlePacket: Audio info[rtplive/_definst_/mpegts.stream]: {AACFrame: size: 0, rate:44100, channels:2, samples:1024, errorBitsAbsent:true, profileObjectType:2} INFO server comment - LiveStreamPacketizerCupertino.handlePacket: Video codec: H264 WARN server comment - LiveStreamPacketizerCupertino.handlePacket: Video encoding settings are beyond iPhone/iPod touch recommendations (Baseline/3.0) [rtplive/_definst_/mpegts.stream]: {H264CodecConfigInfo: profile: “Main”, level: 5.1, frameSize: 416x240, aspect: 40/39, } INFO server comment - LiveStreamPacketizerSmoothStreaming.flushPendingAudio: Bitrate[rtplive/_definst_/mpegts.stream]: 132145 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:1 a/v/k:137/213/1 duration:9522 INFO server comment - LiveStreamPacketizerSmoothStreaming.flushPendingVideo: Bitrate[rtplive/_definst_/mpegts.stream]: 802846 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:2 a/v/k:176/369/2 duration:12312 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:3 a/v/k:149/250/1 duration:10377 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:4 a/v/k:271/461/2 duration:18819 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:5 a/v/k:153/321/2 duration:10711 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:6 a/v/k:148/233/3 duration:10310 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:7 a/v/k:179/319/3 duration:12412 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:8 a/v/k:74/152/2 duration:10602 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:9 a/v/k:148/240/4 duration:10311 INFO server comment - LiveStreamPacketizerCupertino.endChunkTS[rtplive/_definst_/mpegts.stream]: Add chunk: id:10 a/v/k:158/307/5 duration:11011 INFO rtsp disconnect 2025468997 - INFO rtsp connect 1744914299 - {AACFrame: size: 0, rate:44100, channels:2, samples:1024, errorBitsAbsent:true, profileObjectType:2}:12 10 INFO rtsp describe 1744914299 - {AACFrame: size: 0, rate:44100, channels:2, samples:1024, errorBitsAbsent:true, profileObjectType:2}:12 10 INFO rtsp describe 1744914299 - WARN server comment - RTSPCore.setup: track missing: mpegts.stream INFO rtsp play 1744914299 - I’m using a Wowza Developer Edition (the Free Download) ---
