I'm pretty sure these lines should read:
for (y=0; y < 300; y++) {
for (x=0; x < 420; x++) {
for(int k=0;k<3;k++) {
if(k==0)
tmp_frame->data[0][y*tmp_frame->linesize[0] + 3*x +k]= ((gdim-
>tpixels[y][x] >> 16) & 0xff);
else if(k==1)
tmp_frame->data[0][y*tmp_frame->linesize[0] + 3*x +k]= ((gdim-
>tpixels[y][x] >> 8) & 0xff);
else
tmp_frame->data[0][y*tmp_frame->linesize[0] + 3*x +k]= (gdim-
>tpixels[y][x] & 0xff);
}
}
There is probably a quicker and easier way of copying the buffers.
Although I've never used GD so don't know how it stores it's image.
You might be able to use an RGB32 buffer and do a straight memcpy()
per line.
