Display PCR, DTS, PTS, bitrate, jitter of a mpeg TS.

viewts - Display timestamps and related feature

viewts is a tool to analyse pts, pcr and dts in a ts MPEG2 stream.

Qt and QCharts are needed for this project.

Already compiled binaries (for windows and linux) are available in https://github.com/OlivierLeBozec/tstools/releases

Feature

Display :

• PCR, PTS, DTS
• continuity counter error
• Random access point
• Bitrate
• PCR jitter
• Diff between timestamps
• ES buffer level, basically the VBV

Other features :

• X axis can be set to time or packet number
• Save data into file
• command line interface
• ts file drag and drop
• zoom on data

Compile

Github action is configure to test and compile this project.

Check file .github/workflows/main.yml to see how to compile

This project contains viewts and tstool. They can be compiled separatly. tstool is a "subproject" of viewts. Unfortunatly for tstool I had to include googletest code in this project cause download of tag 1.8.1 failed.

viewts's Issues

viewTS : Compilation issue for Linux

It seems function's pointer is not allowed. Strange as it works for Windows.

Add CC errors detection

Add CC errors detection

Crash when starting several threads in parallel

On a big file start PCR processing, then untick the PCR box : the thread is still running in background.
Start the PTS analysis -> Crash.

Provide release for Linux

Dev and compilation is done under linux (centos) but I need to provide rpm with correct Qt dependencies.
Issue is I don't see what package is requested for Qt runtime libs.
Any ideas?

[TO DO] Set the chart in seconds instead of packet number

Add PCR discontinuity detection

UDP Multicast

Bonjour Olivier,

En cherchant un outil pour mesurer la stabilité d'un stream ts, je suis tombé sur ton projet.
Je voulais savoir si il était possible de lire un flux udp ou rtp, multicast ou unicast ?

Bien à toi,
Cordaliss

Add RAP detection

From Mickael request.
Add Random Access Point detection.

Speed up analysis

Analysis is done several times. Not effective for huge files.
-> Analyse once then display data upon selection.

[TODO] Make Drap and Drop working

Add menu to change the color of the graph

[TO DO] Implement buffer level chart

Count the number of byte then flush when PTS or DTS is reached.
Need to know which data is related to specific PTS or DTS.

Add PCR, PTS, DTS period chart

The period is the time between two conscutive timestamp

big files > 4GB seems overflow in file size

Percentage of loading is wrong (several times 100%). I suspect an overflow in file size

Sometimes the application is still running (processes) after a close

Maybe the threads are not terminated correctly.

The Dts-Pts is negative

Display Pts-Dts instead
