Hi,

I am trying to send a video file from Android to C using tcp/ip protocol. When android sends a video file, i am able to receive the file, but when i play the file the file is not getting played and moreover if the actual file plays a video for 2 minutes after receiving using tcp/ip the video size is about 3 hours 5 minutes and so on...

long long int receive_text(long long int socket)

{

   long long int buffersize = 0, recv_size = 0, size = 0, read_size, write_size;

   char textarray[8196000],errno;

   char verify[15] = "text Received";

   FILE *text;

   //Find the size of the text

   read(socket, &size, sizeof(int ));

   //Send our verification signal

   write(socket, &verify,sizeof(char));

   //Make sure that the size is bigger than 0

   /*if(size <= 0 )

   {

           printf("Error has occurred. Size less than or equal to 0 \n");

           return -1;

   } */

       text = fopen("/home/sosdt009/Desktop/receivedandroid.mp4","w");

       if( text == NULL)

   {

           printf("Error has occurred. text file could not be opened \n");

           return -1;

       }

       //Loop we have not received the entire file yet

       while(recv_size < size)

       {

               ioctl(socket, FIONREAD, &buffersize);

           //We check to see if there is data to be read from the socket

           if(buffersize > 0 )

   {

            if(read_size = read(socket, textarray, buffersize) < 0){

        printf("%s", strerror(errno));

       }

            //Write the currently read data into our text file

           write_size = fwrite(textarray,1, buffersize, text);

      /* if(write_size != buffersize)

       {

         printf("write and buffer sizes are wrong \n");

       }

       if(read_size != write_size)

       {

           printf("error in read write \n");

       }  */

       //Increment the total number of bytes read

      recv_size += read_size;

       //Send our handshake verification info

   write(socket, &verify,sizeof(char));

   if (read_size == write_size)

               {

                   printf("%lld,%lld", read_size, write_size);
                   printf("text successfully Received! \n");

                   }

           else

               {

                   //sleep(1000);
                   printf("%lld,%lld", read_size, write_size);
                   printf(" Data Received successfully: \n");

               }


     }

     }

   fclose(text);

   return 0;
