About improving the quanlity of the MPEG4 encoder for PCA?


I have compiled and run both the MPEG4 encoder sample for IA32/64 and PCA, under Linux/PC enviroment, with a little portting work.
The IA32 sample generates fairly good quanlity video, but for PCA
the inter-encoding result is very poor. Looking at the code I find
that the IA32 sample doesn't use the IPP motion estimation functions
but implements its own version, using functions not available in the
PCA version of IPP. I also tried the MVFAST functiosn in IPP, but it
doesn't make any difference. My question is:

1. Is the motion estimation functions in IPP not as good as that
found in the IA32 sample implementation?

2. Do your guys have some guideline on improving inter-encoding
qunanlity of the PCA sample?

3. The documentation of the ME algorithms is not clear on some
function arguments, where to find more information about it?

we arehappy to inform you about availability of the next version, IPP v5.0 beta. In this version we have extended MPEG4 API design on Xscale part of IPP as well. Youcan downloadIPP for IXP 4xx processors, and IPP Media sample. Please visit http://www.intel.com/software/products/ipp/beta/to participate in IPP v5.0 beta program
