Hi,FreeScale
I meet a very strange question on blit image which with G2D_I420,I blit image with physical continued memory as below,if the source image with 576*360,blit success,but if with 480*300,blit failed,how can i fix this?
int width = 480;
int height = 300;
int o_width = 320;
int o_height = 240;
g2d_buf* mpInputBuf = g2d_alloc(width * height * 3 / 2, 0);
g2d_buf* mpOutputBuf = g2d_alloc(o_width * o_height * 4, 0);
mInputSurface.planes[0] = mpInputBuf->buf_paddr;
mInputSurface.planes[1] = mpInputBuf->buf_paddr+ a_width*height;
mInputSurface.planes[2] = mInputSurface.planes[1] + a_width*height / 4;
mInputSurface.left = 0;
mInputSurface.top = 0;
mInputSurface.right = width;
mInputSurface.bottom = height;
mInputSurface.stride = width;
mInputSurface.width = width;
mInputSurface.height = height;
mInputSurface.rot = G2D_ROTATION_0;
mInputSurface.format = G2D_I420;
mInputSurface.blendfunc = G2D_ZERO;
mInputSurface.global_alpha = 0; //Global alpha value 0~255
mInputSurface.clrcolor = 0;
mOutputSurface.planes[0] = mpOutputBuf->buf_paddr;
mOutputSurface.left = 0;
mOutputSurface.top = 0;
mOutputSurface.right = o_width;
mOutputSurface.bottom = o_height;
mOutputSurface.stride = o_width;
mOutputSurface.width = o_width;
mOutputSurface.height = o_height;
mOutputSurface.rot = G2D_ROTATION_0;
mOutputSurface.format = G2D_RGBA8888;
mOutputSurface.blendfunc = G2D_SRC_ALPHA;//G2D_ZERO;
mOutputSurface.global_alpha = 0; //Global alpha value 0~255
mOutputSurface.clrcolor = 0;
if(0 != g2d_make_current(mhG2d, G2D_HARDWARE_2D))
{
return -4;
}
g2d_enable(mhG2d,G2D_BLEND);
if(0 != g2d_blit(mhG2d, &mInputSurface, &mOutputSurface))
{
g2d_finish(mhG2d);
return -5;
}
g2d_disable(mhG2d, G2D_BLEND);
if(0 != g2d_finish(mhG2d))
{
return -6;
}
