What is an expected performance of H.264 ?

I mean possible encoding/decoding fps on some given hardware, codec profile, resolution for IPP5.2 on Windows ?

Hello,

you may use IPP media sample to test IPP H.264 codec with your specific data and on your specific platform.

Regards,
Vladimir

Thank you, but I want to compare it with my specific data and my specific platform to verify that everything works ok.

then you need to askthe data for specific video resolution, profile/level or other features and sw/hw platform of your interest. If we can test we can provide you info. As I understand you are interested in decoder performance, correct?

I tested H.264 for encoding 1920*1080 HD video. The encoding was only a few frame per second, far from real-time. Here is some info about the test.

Computer: Xeon 3.4 G hyperthreading 4 cpus

H.264 parameters:

/* CommentLine: H.264 Sequence.*/
hd_1920_1080_422.yuv10 /* name of source files */
