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
