Please help me in the following problem

I downloaded a project named GMF bridge and play from the link [^]
It takes the file as input and plays it the file contain the h264 data i.e. the NAL units so instead of sending the file path i parsed the file and takes the nal unit into an array and give the array instead of file path,
But the file doesn't play....
Please help me

What am i doing is

char* path=ofn.lpstrFile;
		 FILE* infile;
		 infile= fopen(path, "rb");


    if (infile == NULL) { fprintf( stderr, "!! Error: could not open file: %s \n", strerror(errno)); exit(EXIT_FAILURE); }
		 size_t rsz = 0;
  
	long lSize;
    char * buffer;
	//byte buffer;
    size_t result;
 
	
	fseek (infile , 0 , SEEK_END);
   lSize = ftell (infile);
   rewind (infile);
   buffer = (char*) malloc (sizeof(char)*lSize);
   //buffer = (byte) malloc (sizeof(char)*lSize);
  if (buffer == NULL)
  {fputs ("Memory error",stderr); exit (2);}

  // copy the file into the buffer:
  result = fread (buffer,1,lSize,infile);
HRESULT hr = m_pPlayer->AddClip(buffer, &pClip);

Rest code is same i have mentioned where my code fails if i give the buffer
