Dear experts,
Currently I amworkingupon Intel PXA27X platform providing MPEG-4 encoding feature, but unfortunately, the performance is far from my expectation. On average, encoding an 176x144 P-VOP video frame costs me about 60 ms, definitly unacceptable. By carefully analyzing the codec, the following primitives may be the bottleneck in my project, as follows:
- ippiSumNorm_VOP_MPEG4_8u16u(6.3 ms)
- ippiMotionEstimation_16x16_SEA(420 us)
I am curious about the performance of these primitives in Intel, could any experts provide me such kind of information with which I can target the actual problem at my concern.
By the way, my IPP version is 5.0 for Linux.
Regards,
Yipan
