Hi,

I use Wowza media server 3.0 as a VoD (RTSP) server for STBs.

The server streams AAC files using MPEG-TS packets.

I have two questions:

1- How may i force RTSP server output to use UDP instead of RTP?

2- How can i change Packetizer to increase PMT/PAT insertion?

Thanks in advance

Hello,

Take a look at the [How to re-stream video from an IP camera (RTSP/RTP re-streaming tutorial](https://www.wowza.com/docs/how-to-re-stream-video-from-an-ip-camera-rtsp-rtp-re-streaming#config), step 3e. The properties available for controlling outgoing MPEG-TS are described [here](https://www.wowza.com/docs/how-to-control-video-and-audio-pid-and-streamids-for-outgoing-mpeg-ts).
