g2d_blit_2d: fail with status -20

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;

}

Hi yong

recommended to try latest Vivante v5.0.11p7.4 gpu library (included

in L3.14.52), attached document Table 9. New features shows its

improvements.

Best regards

igor
