TS Analyze

A TS packet start with 4 bytes header, total length could be 188, 192 or 204 bytes. Most system will use 188 bytes.

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

Two methods: start with

- autogen.sh
- cmake

and then do make for both ways

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
