Begin coding/decoding H.264

Hi, I am new in IPP so I don't know where I must start. I need to capture images from the webcam and the coded in H.264. I compiled almost all the media sample but when I used video_enc_con for encoder a YUV raw video. Then I tried to play it but and error appear.

I'd like know a tip where I can begin to develop de encoder H.264 (or a sample based)

Thank a lot!

I may suggest to get the latest version for example:

the latest product release: 5.3 update 3 (http://www.intel.com/software/products/ipp)
or the latest IPP 6.0 beta version (http://www.intel.com/software/products/ipp/beta)

When you recheck this issue with newer version, please ensure upgrade both libraires and sample.

Please let us know how it works with new version.

Thanks,
Ying
