I have downloaded and tried the IPP H264 sample codec provided in the w_ipp-sample-video_pu_4.1.008 samples package. However, it doesn't appear to support B frames. Only I and P frames are produced.
Looking at some of the meassages on this forum, it appears that there may be a newer H264 sample codec that uses IPP beta 5.0 and that produces B frames.
Please let me know where could I download the latest IPP sample H264 codec from.
