[linux-dvb] Help with pipe/fifo

["Andrea Gerardi" <gerardi_andre79@hotmail.com>]

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++;
					}
				}

		}
