I want to use UIC library to decode MJPEG frames (input format 420) in YUV422 interleaved format or YUV420 planar (if it is possible).
I was able to do it correctly with the old IJL library: I decode the frames in RGB format and then convert to YUV420 (which is our preferred format to render the frames on video memory).
Now I am trying to use the IPP 7.0/7.1 libraries (using the UIC JPEGDecoder class), but I have some problems.
I have wrote the code based on the example that I have found in the documentation and on the forums. I do not have any error during the code execution, but the output buffer remains with all zeros.
Where could I find an example to decode MJPEG 420 frames with UIC?
