How use g2d to convert image data from yuv422 to yuv420?

[zoechen]

Hello everyone,

     I want to use g2d to convert my image data from yuv422 to yuv420, so I set it as follow:

src.format = G2D_UYVY;

    src.planes[0] = src_buf->buf_paddr;

    src.left = 0;

    src.top = 0;

    src.right = width;

    src.bottom = height;

    src.stride = width;

    src.width = width;

    src.height = height;

    src.rot = G2D_ROTATION_0;

    dst.format = G2D_I420;

    dst.planes[0] = dst_buf->buf_paddr;

    dst.planes[1] = dst_buf->buf_paddr + width + height;

    dst.planes[2] = dst_buf->buf_paddr + width + height * 2;

    dst.left = 0;

    dst.top = 0;

    dst.right = width;

    dst.bottom = height;

    dst.stride = width;

    dst.width = width;

    dst.height = height;

    dst.rot = G2D_ROTATION_0;

Then the log tell me "g2d_blit_2d: Invalid dst format 21!", whether g2d do not support yuv format as dst format?

BR,

Hi Zoe,

    For linux 3.0.35, g2d only supports YUV to RGB output.

    For linux 3.10.xx g2d supports YUV422 & RGB output.

    But not support YUV422 to YUV420 output !!

Hi weidong.sun​

Does g2d able to do color space conversion from RGB24 to RGB565?

Thanks
