Hi,

I use Panasonic IP camera.

I force it (camera device) to publish RTP packets to UDP port let it be p1 = 10500 on IP i1 = 192.168.10.109.

I use stream file:

```auto
{
  "uri": "udp://192.168.10.109:10500",
  "rtpTransportMode":"udp"
}

```

There is no video output in player.

I see the following warning:

```auto
MPEG2MPTS:processNewBuffer: java.lang.IllegalArgumentException: Transport packet started with 0x90

```

If we use RTSP url video will work.

It’s Ok.

But, RTSP is just signaling protocol, media is deliveried via RTP over UDP or TCP.

So where is a problem when we just push RTP packets to known UDP port?

Richard, we use payed version of Wowza. Solutions to this problem will increase a number of our licenses.

Gstreamer / FFMPEG does opens the stream.

Thanks any ideas appreciated.

Can you please provide the video codec you are sending from the camera.

Greetings,

having the same problem here with a Funkwerk encoder.

Did you solve that problem?

Thanks, Stephan

Hello Stephan,

This error:

```auto
MPEG2MPTS:processNewBuffer: java.lang.IllegalArgumentException: Transport packet started with...

```

Potentially looks like an encoder issue. It could be that your encoder is splitting MPEG transport packets, and across the UDP packet boundaries.

Usually encoders have a way of configuring this.

Here is a forum response from a similar situation:

> My encoder was set to the normal setting of 7 MPEG packets per IP packet.
> 
> Through an educated guess based on your suggestion of splitting packets, I changed the encoder to output only 1 MPEG packet per UDP packet, restarted the stream, and it came right up.

If you are still having trouble with this please open a ticket by sending the following folders zipped to support@wowza.com:

**[install-dir]/conf**

**[install-dir]/logs**

**[install-dir]/transcoder**

**[install-dir]/manager/logs**

**NOTE:**

_Wowza may then request additional information, such as the following:_

_A screenshot of your exact live encoder settings._

_A copy of your .stream file(s)._

_A sample of a problematic VOD asset (media file)._

_A sample recording of a problematic incoming stream._

_Kind regards,_
