Hi,
We purchased the IPP SDK from Intel about 3 years ago and built a direct show filter to use the SDK to decode H264 video. We use the SDK as a static library. Our decoder filter is based on the w_ipp-samples_p_7.0.5.059 sample from Intel.
We ran into a problem recently when we tried to decode video streams in 1080p at 30 fps in 4 mbps or higher. The decoder shows stutter video when it tries to decode an I-Frame. For example, we see cars pause and resume in our video of moving cars every time an I-Frame needs to be rendered. The I-Frame size is between 170K to 200K bytes. We found that the pauses might come from the GetFrame() call. It takes the function about 100 milliseconds to decode an I-Frame.
Is this a known problem? Is there a new version of IPP fixes the problem? Any suggestions and help would be greatly appreciated.
Thanks
