IPP library and NAL unit???

Cristina_Gil — Wed, 24 Feb 2010 10:06:50 GMT

Hello,

I get the NAL unit and i defragmented it so when i get an IDR or non-IDR type i read the slice header but now, i want to use the slice data (which i know the beginning and the end of each one) and get the picture (and then, the video).

I think i could use the IPP library to do that but im such a newbie i dont know where to begin. Do you think IPP library fits in my development? Which one?

I program in VB.net but maybe it could be easier to do it in C.

I hope you can give advice. Thanks for your help.

Hello,

What information do you want to get from the NALs units? It looks you want to decode the NAL units, and get the decoded video frames.

You can take a look at IPP UMC sample, and this get started article:

http://software.intel.com/en-us/articles/getting-started-with-intel-ipp-unified-media-classes-sample

For the simple H.264 decoder example, it takes NAL units data, and decode into YUV frame. UMC sample is based on C/C++, C++ code would be some easier to use them.
