https://community.intel.com/t5/Intel-Integrated-Performance/JPEG-Example/m-p/875646#M9477 <P>Hi,<BR /><BR />I'm building an app for video validation. Most of the time we record frames as uncompressed YCbCR (normally 8bit 4:2:2) but we are finding a need to archive some of our content offline for reference. I already use IPPI for a lot of internal transforms and image testing, so I'm looking at a using IPPJ to do a lossless (must be absolutely lossless) frame by frame compress that we can inject silently into our existing tool chain.<BR /><BR />my big problem is that all of the examples that I can find rely heavily on some sort of buffer stream library (I already have more of those than I need with the video) and my data is already in YCbCr.<BR /><BR />Can anyone outline or point me at a simple example of the sequence of <STRONG>IPP</STRONG> calls I should have to make to encode/decode and what they expect?</P> Thu, 02 Oct 2008 00:57:23 GMT Thaddeus_L_Intel 2008-10-02T00:57:23Z https://community.intel.com/t5/Intel-Integrated-Performance/JPEG-Example/m-p/875646#M9477 <P>Hi,<BR /><BR />I'm building an app for video validation.
