how to get PMT(Program map table)

1. offizieller Beitrag

    I am simply using dvbsnoop-1.4.50
    i have to analyze a stream that is on the PC
    and extract the Program map table (PMT).
    I can just use this commande write now :


    dvbsnoop -if MPEGIO_MPEG2_176X144_Video1024Kbps.mpg -n 1 -nph 0x010> /home/sami/out.txt


    /////////////////////////////////out.txt///////////////////////////////////////////////////////////////////////////


    dvbsnoop V1.4.50 -- http://dvbsnoop.sourceforge.net/

    PID: 16 (0x0010) [= assigned for: DVB Network Information Table (NIT), Stuffing Table (ST)]


    Guess table from table id...
    PAT-decoding....
    Table_ID: 0 (0x00) [= Program Association Table (PAT)]
    section_syntax_indicator: 0 (0x00)
    (fixed): 0 (0x00)

    CRC: 0 (0x00000000)


    no box used


    My questions are :


    1- How can i get the PMT from the stream


    2- How can i get access to à specific stream 0x52 in that pmt


    all documentation, site refference, or advise are welcome


    :grinning_squinting_face: Gys i realy need answers it is a life or death matter


    thank you

    Even enigma1 will not write a /tmp/pmt.tmp without a special patch to support an outdated program, which we will not discuss here. So you can patch enigma2 in the same way.
    (But hey, everything you need is in camd.socket - and there are lots of programs which will dump the content of camd.socket to a file)


    @laith:
    You can acces a special stream inside a TS file with dvbsnoop - you dont need the pmt for that. The pmt is only a description, which streams inside the ts stream belongs to the service. So if you already know the stream-id (0x52) - you should be able to extract this stream whith dvbsnoop (something like dvbsnoop -if MPEGIO_MPEG2_176X144_Video1024Kbps.mpg 82 should do the trick)
