Here is a C code to read 2 frames from the CIF file

unsigned char ybuffer0[240][352]; // the y buffer
unsigned char crbuffer0[120][176]; // the cr buffer
unsigned char cbbuffer0[120][176]; // the cb buffer

unsigned char ybuffer1[240][352]; // the y buffer
unsigned char crbuffer1[120][176]; // the cr buffer
unsigned char cbbuffer1[120][176]; // the cb buffer


int fd; // pointer to the input file

int read2frames() 
{
 // Open the input file 
    fd = open ("foreman_qcif_0001.yuv", O_RDONLY) ;
 
 // Read the first frame 
    read (fd, ybuffer0, 240*352);
    read (fd, crbuffer0, 120*176);
    read (fd, cbbuffer0, 120*176);
 
 // Close the input file 
    close(fd);

  // Open the input file 
     fd = open ("foreman_qcif_0002.yuv", O_RDONLY) ;
 
  // Read the second frame 
   read (fd, ybuffer1, 240*352);
    read (fd, crbuffer1, 120*176);
    read (fd, cbbuffer1, 120*176);

 // Close the input file
    close(fd);

}
