Hi, I faced some strange issue with the stream from Edimax IP cameras. Edimax codecs: H264 (Constrained Baseline Profile)/G.711 **Video doesn’t work.** **But there is audio!!!** And there are a lot of errors inside log file. ```auto 2014-04-03 14:08:53 IDT comment server ERROR 500 - LiveStreamPacketizerPacketHandler.handleHolder[live/_definst_/test.stream] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.createChunkM4S(MPEGDashWriterHandler.java:1435)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.endChunk(MPEGDashWriterHandler.java:507)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.endChunk(LiveStreamPacketizerPacketHandler.java:1031)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.handleHolderInternal(LiveStreamPacketizerPacketHandler.java:793)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.handleHolder(LiveStreamPacketizerPacketHandler.java:597)| ``` I checked with FFPROBE ```auto ffprobe rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp Input #0, rtsp, from 'rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp': Metadata: title : IPCam Duration: N/A, start: 0.000000, bitrate: 64 kb/s Stream #0:0: Video: h264 (Constrained Baseline), yuv420p, 640x480, 15 tbr, 90k tbn, 180k tbc Stream #0:1: Audio: pcm_alaw, 8000 Hz, 1 channels, s16, 64 kb/s ``` VLC: ![](http://imageshack.com/a/img823/6029/p3v6.png) Thanks, any ideas appreciated ---

Hi, When you say that video doesn’t work, can you please be more specific? Which streaming protocol are you using for playback? Which player? Zoran ---

Hi, I’ve added the properties. But still. There is no video There is audio ```auto { "uri": "rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp", "rtspFilterUnknownTracks": "true", "rtpIgnoreProfileLevelId": "true", "rtpIgnoreSPropParameterSets": "true" } ``` And NullPointerException in logs: ```auto 2014-04-03 14:10:04 IDT comment server ERROR 500 - LiveStreamPacketizerPacketHandler.handleHolder[live/_definst_/test.stream] : java.lang.NullPointerException|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.createChunkM4S(MPEGDashWriterHandler.java:1435)|at com.wowza.wms.httpstreamer.mpegdashstreaming.livestreampacketizer.MPEGDashWriterHandler.endChunk(MPEGDashWriterHandler.java:507)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.endChunk(LiveStreamPacketizerPacketHandler.java:1031)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.handleHolderInternal(LiveStreamPacketizerPacketHandler.java:793)|at com.wowza.wms.httpstreamer.model.LiveStreamPacketizerPacketHandler.handleHolder(LiveStreamPacketizerPacketHandler.java:597)| - ``` I could open IP camera to outside. ---

Ok. Solved. **RTPTransportMode: "udp"** **Camera doesn’t support RTP over TCP.** The following JSON works: **GOOD** ```auto { "uri": "rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp", "rtpTransportMode":"udp" } ``` Thanks
