MPEG2 Decoder Meta functions

[Alex_B_4]

Hello,

I am attempting to create a MPEG2 decoder using the guidelines in the documentation ippiman.pdf (page 16-116). When feeding in a valid MPEG2 stream to ippiReconstructDCTBlockIntra_MPEG2_32s, I get a the ippStsH263VLCCodeErr error returned. I suspect that the error is due to inproperly creating the DC and AC tables, but cannot be certain. Can anyone provide sample code that uses this function and sets up the parameters? The IPP sample code for both 5.1 and 5.2 do not use this function.

Also, is there a location where I can find the sample code for IPP 4?

Thank you,
Alex

Alex,

Why you can't use new functions, which are used in IPP 5.1 and 5.2? There was a reason to deprecate this functions, as a new ones provide more efficient way in decoding. We do not provide sample code for IPP 4.0

Vladimir

I am using IPP 5.1. And trying to follow the steps listed in the manual (which specifically call out using ippiReconstructDCTBlockIntra_MPEG2_32s). Where are the new functions mentioned in documentation? Where does documentation mention that this function is depreciated?

Thank you,
Alex

Alex,

did you look at IPP media sample, which contains MPEG2 decoder and encoder and sample application to demonstrate their work?
