Dear All,
We are using IPP verion 7Package ID: w_ipp_7.0.1.127 w_ccompxe_2011.1.127 and samplesw_ipp-samples_p_7.0.7.064
We are receving stream from IP camera and decoding for analytics purpose
When we set fps = 15 in camera and try to decode with MJPEG decoder we are getting only 7-8 fps, if we find SOI and EOI and pass to JPEG decoder we are getting 13 - 14 fps
Please help
Thanks,
Vikas K R

Hi Vikas,
Do you use multi-threaded decoder? If yes, try to build single-thread decoder, or you may continue compile decoder as multi-threaded, but build the final application with single-thread IPP libraries. It may happen, that oversubscription takes place here.
Reply how it goes.
Regards,
Sergey

Hi Sergey,
Where do we do this?
We are usingm_pVidDecparams->numThreads = 1, this should be single thread decoder right?

Good day.

Can you share this stream? I'd like to take a look.

Sorry my bad :(
Issue Solved, after decoding one image, we cleared my receiving buffer which actually had next frame data, because of this used to get half frame rate
Now getting full frame rate :)
