[linux-dvb] Help with pipe/fifo

[Andrea Gerardi]

Hi
where I could find sample using pipe/fifo for ts decoding? I would use pipe 
so the entire stream received, could be processed to retrieve all pid 
transmitting over a transponder (tuned by dvbtune). Now I am using this code 
but there a problem on decoding pid: child's get out only pid 0 (scan decode 
other pids)!
I think the problem is in write-end pipe but I dont know how resolve! Could 
you help me in anyway?  thanks of all. Andrea

//parent write-end fd[1]
while((read(fd_dvr,tmp,10*TS_SIZE))!=0){
			write(fd[1],tmp,10*TS_SIZE);

			}

//child read-end fd[0]
if((read(fd[0], mbuf, TS_SIZE))0) perror(\nerror reading pipe\n);
for (i = 0; i  TS_SIZE ; i++)
{
if ( mbuf[i] == 0x47 ){
printf(\nFound sync byte at %d\n,i);
break;
}
}
if (i == TS_SIZE)
{
perror(\nNot a TS\n);
return -1;
}else{
memcpy(buf, mbuf+i, TS_SIZE-i);
	while((read(fd[0], mbuf, i))!=0);

memcpy(buf+TS_SIZE-i, mbuf, i);
//my_get_bits() function ok!
point_bit=11;
	i=my_get_bits(buf,13);

	printf(\nFirst pid: %04x\n,i);

	point_bit=0;

l=0;
while((read(fd[0], buf, TS_SIZE))!=0){
//read(fd[0], buf, TS_SIZE);
point_bit=11;
i=my_get_bits(buf,13);
printf(\nFound pid %d: %04x 
%d\n,l,i,i);
point_bit=0;
l++;
}
}
		}

[linux-dvb] Pipe ok! Set filtering dmx...

[Andrea Gerardi]

Hi list
my pipe is ok! The last question is: there's a way to set the 
dmx_pes_filter_params.pid = ANY_PID  to obtain each pid on the transponder? 
This is my last limitations, please send me a reply! Thanks to all.

[linux-dvb] Pipe?

[Andrea Gerardi]

Hi list,
I need use pipe to analyze consecutive pid of ts. With this code:
if(pid=fork()0) perror(\nfork error\n);

else if (pid0)
{//parent
close(fd[0]);
//tuning operation and get fd_dvr handle
   close(fd[1]);
if (waitpid(pid,NULL,0)0) perror(waitpid error);
exit(0);
}
else if (pid==0)
{//child
close(fd[1]);
close(fd[0]);
exit(0);
}

ReHI list,
excuse for mistake!!
So, I use a fork (such as you seen previously) to get ts from a pipe. But

[linux-dvb] Reader idle

[Andrea Gerardi]

Hi list,
I'm using API 3.0  to develop a Ts-reader with this pes filter:
struct dmx_pes_filter_params flt;
if((ioctl(fd_demuxv, DMX_SET_BUFFER_SIZE, TS_BUF_SIZE))0){
perror(DMX_SET_BUFFER_SIZE failed:);
return -1;
}
memset(flt,0,sizeof(struct dmx_pes_filter_params));
flt.pid = pid;
flt.input   = DMX_IN_FRONTEND;
flt.output  = DMX_OUT_TS_TAP;
flt.pes_type = DMX_PES_OTHER;
flt.flags = DMX_IMMEDIATE_START;
 where
#define TS_BUF_SIZE 4096
but when I test the sw (after sint. with dvbtune), it work fine only 1 time 
otherwise stop itself at :

n = read(fd_dvr,buf,sizeof(buf));   uint8_t  buf[188];

and my terminal doesn't show anything (no error, no message, nothing) so I 
don't know where it the problem!!!

Note: after insmod or reboot my sw  go well; at the second chance stop! 
Why?Thanks
