How to record IP streams through TS Reader? 

  • <Download>

Please download "TSReader Retail" from my dropbox space:


  • <Setup>

Then set up TS Reader, its password is "mpeg4u".

  • <Analyze>

Run TS reader and select source for different source types as below:

*File.dll: if the source is a TS file on your disk;

*UDPUnicast.dll: if the source is IP stream via Unicast;

*UDPMulticast.dll: if the source is IP stream via Multicast;

Note: please connect the PC to the Data port of our equipment while analyzing its IP 

output stream. Multicast mode is suggested because this mode is simpler.

  • <Record>

Use menu: [Record] -> [Record Mux] to record current stream into a file.

#Note: Problem playing multicast UDP streams

If you can not find the stream, please try the following steps:

1. Check if IP output is enabled on the source device;

2. Multicast address is suggested, but please use a direct connection between the source and PC to 

avoid switch/router setting issues.

3. Disable the firewall on the computer;

4. Disable the wireless network adapter;

5. Restart the computer;

6. Run TS Reader again
