# 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
