tsetr290

Validate Transport Streams Useful for checking standards compliance of transport streams before sending for broadcast. Some code blatantly ripped from tstools from zhoucheng and opencaster.

I'm not a educated programmer so any improvements or wtf's feel free to let me know or make it better yourself. Python GUI for this will be made in another repo.

git clone https://github.com/Emerica/tsetr290.git
cd tsetr290
make
./tsetr290 filname [bitrate] [reports]
./tsetr290 mytestfile.ts
./tsetr290 mytestfile.ts 15000000

make install

tsetr290 filname [bitrate] [reports]
tsetr290 mytestfile.ts
tsetr290 mytestfile.ts 15000000 1

OR with docker/bind mount

%SOURCEDIR% = A directory with TS files you want to scan.

%MEDIAFILE.ts% = A Transport Stream in the directory

%BITRATE% = The expected bitrate (optional)

%REPORTS% = Optional reports (optional)

git clone https://github.com/Emerica/tsetr290.git
cd tsetr290/docker
docker build -t tsetr290:latest .
docker run -i -t --mount type=bind,source="%SOURCEDIR%",target=/scan tsetr290:latest \ 
  /usr/local/bin/tsetr290 "/scan/%MEDIAFILE.ts%" %BITRATE% %REPORTS%

If bitrate is not supplied it will be calculated from the PCR values. This is not optimal if you are looking for a proper report. Timing accuracy will suffer until the rate has been established.

If reports is set, a set of delta reports will be created which can be graphed.

Most checks that don't require buffering have been implemented, possibly incorrectly. I haven't had a need to pass L3, most providers on seem to require L1 and L2. Feel free to implement the remaining checks.

Links to the refference decoder would help here. mpeg2dec? It seems mpeg.org has had a Joomla problem for weeks and hasn't been bothered to fix it.
