[gst-devel] Query regarding usage of GST_BUFFER_DATA

[irfanshaikh]

Hi all,

         I want to fill the tempbuf bellow after some processing as i have
explained below. Once the tempbuf is full i need to pass its base adres to
another function.
I just wanted to ask can i use 2 buffer poiters such as *data_one and
*data_two
         1. data_one :- For filling tempbuf
         2. data_two :- to send base address of buffer, to some fuction Y.

Please tell me if i can use it this way  and i am correct ...


Whether *data_two is pointing to initial position of data in tempbuf...And
tempbuf is filled properly with help of  *data_one...Can i use *data_one to
pass in function_Y...so as itz serving the purpose


    _chain(GstBuffer buf)
  {
        GstBuffer tmpbuf;
        guint8 *data_one, *data_two;
        tempbuf=gst_buffer_new_and_alloc(300*sizeof(guint8));
        data_one=GST_BUFFER_DATA(tempbuf);

        function_X()
        {
             memcpy(tempbufdata, buf, 100);
             tempbufdata += 100;

             /*Do some processing*/
             memcpy(tempbufdata, buf, 100);

             /*Do some procesing*/
             memcpy(tempbufdata, buf, 100);

            data_two=GST_BUFFER_DATA(tempbuf);

            function_Y(data_two);

        }
  }
