DM6467 Read an BMP picture from the disk

thanks

            according to your replies, the Loader module can't not be used? Shoule all the programs  be written?  Have any other methods?

thanks

Hi,

I am not sure what is loader module? But display supports only YUV422 SP data.

Thanks,

loader module is contained in the DMAI of the DVSDK, like the function Loader_create() \Loader_prime(),and so on ,which are used in Implements an elementary stream file loader.

hi,

I am not sure how dmai module does. This can be easily by removing header from bmp file and converting rgb to yuv444 and then to yuv422.

Thanks,

hi

       the depth of the bmp is 8 bits, when it is converted to YUV, should it have Y,? So  we can give the Pixel value to Y directly?  what I do is right?

   thank you!

Hi,

That depends on how you convert and store in the buffer. You can convert RGB data in BMP file into YUV and store Y and CbCr data in separate buffers so that it can be displayed using VPIF display driver.

Thx,

hi

thank you for your sincere reply, but I still can not catch it, I think an 8 bit depth bmp has only Gray information without chrominance information. When it is converted to YUV, it should have Y and no Cb,cr. I don't know if  what I understand  is correct?
