Stream SRT using an R PI

Intro

Faced with the challenge of conducting tests in a mobile environment, I needed a portable and efficient solution. Then, inspiration struck! I realised I could leverage the SRT Cookbook and tsduck to create a compact playout system. Here’s how I brought this idea to life…

Equipment

• RPi 4 Model B
• Case to house this all in
• 32gb SD card
• Rasbpian OS CLI version (headless) v12 bookworm
• TS file

Pre-requisite

Before you embark on this journey you will need to make sure that you have complete the following

• Obtained a TS file there is loads online just perform a google
• Raspbian CLI installed on the PI

Install TSduck

I’ve often encountered difficulties installing tsduck, particularly with dependency conflicts and compilation errors on my Raspberry Pi 4 running Raspberry Pi OS. However, I recently found a comprehensive guide that provided clear, step-by-step instructions, which led to a successful installation.

Syntax !

Once you’ve confirmed the application is installed, let’s explore the syntax used in the following example:

tsp -v -I file -i 60ibars.ts -P  regulate -p 7 -O srt --caller 192.168.1.198:2000 --transtype live  --enforce-burst 

TSP = Transport Stream Processor
-v = Verbose ( allows you to log to a file for telemetric purposes)
-I = Input Library
-i = Input file
-P= This is to alter the transmission speed, in this case it is based on PCR and will regulate
-p= TS packets per UDP packet
-O= Output Library
— caller = SRT caller and address
— Transtype Live = Live stream the alternative is file.
— Enforce Burst = Enforces a static chunk size per UDP packet so in my case is is 7
