TS Analyze

A TS packet start with 4 bytes header, total length could be 188, 192 or 204 bytes which are specified in standard DVB/ATSC/ISDB.

Construct TS packets we will get PES/PSI packets.
PSI is structured for search and other auxiliary functions. 
PES contains ES packets which could be audio or vedio streams.

With this understanding, you can start decoding a TS stream or file now.

  • Use basic rules from ISO 13818 and ETSI EN 300 468 to decode MPEG2 TS
  • Use EN 300 743 to decode subtitle
  • Use ETS 300 706 to decode teletext

Print descriptors for DVB/ATSC/ISDB standard. Print PSI tables infomation and some other subsystem infomation

Compile

We could install pybind11 to build package for python.

for Linux & Macos

git clone https://github.com/junka/tsanalyze.git
cd tsanalyze
mkdir build
cd build
cmake ..
make

for Windows with MSVC

git clone https://github.com/junka/tsanalyze.git
cd tsanalyze
mkdir build
cd build
cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE="C:/vcpkg/scripts/buildsystems/vcpkg.cmake"
cmake --build .

Usage

  • Most simple way
./tsanalyze tsfile
  • Support file and udp stream analyze
./tsanalyze -f udp udp://url_of_stream

Ctrl + C to stop and show received ts information

  • Print table selected
./tsanalyze tsfile -s pat -s cat 
  • Print stats about ts streams
./tsanalyze tsfile -S

descriptor

Not all descriptor implemented now, see doc/descriptor.md to add new descriptors
