[linux-dvb] Re: PID histogram
Hi Felix
FYI
Tried your traffic.c.

i once wrote a tiny program (http://kuehlschrank.ath.cx/traffic.c) which
opens pid 0x2000 and display traffic stats. You may take this as a
start, it will display bitrates and number of received packets.
You have to use some tool like gnuplot etc. to display the data (and
modify the output, of course)
Just for clarification, it seems that for your program to work, one
must excute a program like dvbstream. Is that intended ?
Another problem that I have is that I can only get your
program to work sometimes. 5 out or 6 times it just reads
between 50-1800 packets and then waits in a read().
Sometimes it works and produce something like
bash-2.05a$ ./traffic
0135 2715 p/s 498 kb/s 4084 kbit
0136 136 p/s 24 kb/s 205 kbit
2000 2852 p/s 523 kb/s 4289 kbit
0135 2256 p/s 414 kb/s 3393 kbit
0136 140 p/s 25 kb/s 211 kbit
2000 2397 p/s 440 kb/s 3605 kbit
0135 1700 p/s 312 kb/s 2558 kbit
0136 111 p/s 20 kb/s 167 kbit
2000 1812 p/s 332 kb/s 2725 kbit
0135 1056 p/s 193 kb/s 1589 kbit
0136 118 p/s 21 kb/s 178 kbit
2000 1175 p/s 215 kb/s 1767 kbit
but mostly it ends up waiting.
