#TSParser
TSParser is a Python script used to parse MPEG-2 TS stream.
##DESCRIPTION
You can retrieve the following information by this script.
PSI
PMT (Program Map Table)
SIT (Selection Information Table)
PAT (Program Association Table)
PCR (Program Clock Reference)
ES (Elementary Stream)
You can print out PMT, ES and SIT information by specified PID, or by searching. For searching mode, you can print out all specified table packets, or only unique table packets.
For ES packet, the PES ( Packetized Elementary Stream) header is also printed out. By these information, you can find the start pointer of GOP (Group Of Pictures) or I-pictures.
Three types of packet size (188 bytes,192 bytes, 204 bytes) TS stream can be handled by this script.
##USAGE
TSParser.py -t <188|192|204> -m PAT
TSParser.py -t <188|192|204> -m <PMT|ES|SIT> PID
TSParser.py -s PCR
TSParser.py -s <PAT|PMT|SIT> --all
TSParser.py -s <PAT|PMT|SIT> --unique'''
Example: TSParser.py -t 188 -m PMT 1fc8
###Options:
-
-h, --help
Show this help message and exit. -
-t PACKET_SIZE, --type=PACKET_SIZE
Specify TS packet size[188, 192, 204], default = 188. -
-m MODE, --mode=MODE
Specify parsing mode[PAT, PMT, SIT, ES], default = PAT. -
-s SEARCHITEM, --search=SEARCHITEM
Search PAT/PMT/PCR/SIT packets and output Information. -
--all
Output all PAT/PMT/SIT packets Information. default,only the first one is output. -
--unique
Output unique PAT/PMT/SIT packets Information.default, only the first one is output.
