Edimax IP camera problem

Wowza Streaming Engine
1

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.

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

 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':

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?

Hi,

Can you please add/enable the following .stream properties:

rtspFilterUnknownTracks : true

rtpIgnoreProfileLevelId : true

rtpIgnoreSPropParameterSets : true

Please use the instructions from the following forum article to enable these .stream settings: How to specify per-stream settings in .stream files

Hi, I use RTMP protocol and a player from FlashRTMPPlayer provided with Wowza installation.

Wowza…: 4.0.3

Protocol.: RTMP

Player…: a player from FlashRTMPPlayer provided with Wowza installation

Conf…: Example configuration from example/live

Another IP cams (Panasonic, D-Link) work properly.

Thanks

Hi,

I’ve added the properties.

But still.

There is no video

There is audio

{
  "uri": "rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp",
  "rtspFilterUnknownTracks": "true",
  "rtpIgnoreProfileLevelId": "true",
  "rtpIgnoreSPropParameterSets": "true"
}

And NullPointerException in logs:

I could open IP camera to outside.

Ok.

Solved.

RTPTransportMode: "udp"

Camera doesn’t support RTP over TCP.

The following JSON works:

GOOD

{
  "uri": "rtsp://admin:1234@192.168.10.95:554/ipcam_h264.sdp",
  "rtpTransportMode":"udp"
}

Thanks
