try:
dvbsnoop -s ts -if test.ts -nph -tssubdecode -n 1 0x00
The table is decoded when all ts packets are retrieved.
Be aware that when reading from binary, -n 1 reads only the first packet
whatever its pid. So, better try -n 10000 to have a chance to get the
section.
But the best is to write a little filter prog and run something like that:
cat test.ts | tsfilter 17 | ./dvbsnoop -s ts -if /dev/stdin -nph -tssubdecode
17 | less
ts2filter would look like:
int main(int argc, char **argv)
{
int pid, pid1;
unsigned char buf[188];
pid1=atoi(argv[1]);
do {
n=fread(buf,1,188,stdin);
if (n==188) {
pid = (((buf[1] & 0x1f) << 8) | buf[2]);
if (pid==pid1)
fwrite(buf,1,188,stdout);
}
} while ( n>0 );
}
