This is a tool for analyzing ts

The main purpose is to use a pipeline of cells to process ts

Pipeline

Pipe command

tsanalyzer pipe command will set up a pipeline with multiple connected cells to execute

Pipeline syntax

Cell description

The following command declares a cell with type cellname cellname prop1=val1 prop2=val2 ...

Cell connection

At current phase of development, only 1-in-1-out is supported

! symbol is used as a connection indication:

// setup a pipeline cell1 -> cell2 -> ...
cell1 prop1=val1 ! cell2 prop2=val2 prop3=val3 ! ...

Cell

cell is the basic processing unit in the architecture

Available cells

name	description
file_reader	read from file
file_writer	write to file
bytes_converter	convert bytes to specific format
vbv	processing vbv data
mcast_reader	read from udp multicast

file_reader

file_writer

bytes_converter

vbv

mcast_reader

Alias

you can always use the pipe command to set up a customized pipeline, while the tool will also provide some alias commands for some use case

the alias command is simply use some flags to build up a preset pipeline for processing

Available alias

name	description
vbv	calculate DTS-PCR
cap	capture multicast

vbv

vbv filename -p pcrPid -stream pid1,pid2,pid3 -plot filename

is an alias for

pipe file_reader name=filename ! bytes_converter output_format=ts_packet ! vbv pcr=pcrPid pids=pid1,pid2,pid3 dir=filename.log plot=true

the above pipeline will

• calculate (DTS-PCR) value for pid1 pid2 and pid3
• store the result in filename.log directory
• plot the result and store in the same directory

cap

vbv -t ts -o out.ts eth0 239.1.1.1:1111

is an alias for

pipe mcast_reader intf=eth0 addr=239.1.1.1.1111 ! file_writer name=out.ts

the above pipeline will

• capture the multicast 239.1.1.1:1111@eth0
• extract udp payload and store to out.ts
