I have downloaded the 7.1 IPP samples and noticed that there are 2 jpeg encoder/decoder's. One is in UIC and one is in image codecs. The UIC one uses just IPP but the image codec uses ijg8. Is there a preferred one to use? Does one have better performance? Also the image codec is reliant on the ijg library which is separate from the IPP so does that mean I need to include the IPP and IJG libraries?
