H.264 Support in IPP

Hello,

I wanted to know do the H.264 functions provided in IPP support threading i.e does using ippSetNumThreads() have an effect on the CPU usage for H.264 decoding. Secondly, the 5.3 version of IPP does not have complete support for 16 bit H.264 video decoding, there are some APIs which donot have the 16 bit signature. Does the 6.0 version have this.

Regards,
Raman

Hi Raman,

H.264 functionsare not threaded, so call to ippSetNumThreadsmakes no sense(there is no reason to launch threads to process 2x2 or 8x8 blocks of data). Threading in IPP H.264 decoder implemented above IPP, on codec level.

We do support 10+ bits data in IPP H.264 although not every functionsupport 16-bit data type.

Regards,
Vladimir
