IPP support for AAC LD

pratheekp — Wed, 19 Oct 2011 04:32:19 GMT

Hi experts,
Does IPP support the low delay AAC profile or it supports only AAC LC profile?

Also how can I compare the performance of my AAC codec with and without IPP library?

Please reply to my queries.

Thanks in advance

Hi Pratheek,

UMC AAC codec doesn't support LD. Only LC, HE and HE v2.

Regarding the second question...looks like there is no way to do that. There is no IPP AAC codec without IPP :).

Sergey

Hi Sergey
Thanks for your valuable reply. I think I could not convey my second question properly to you.
I would like to take the performance of whole IPP AAC codec for a particular stream. Is there a method for doing this. (In the IPP library I downloaded, there are seperate .exe files to test the functions in various domain. If i run ps_ippac.exe I get a profile report which gives me the cycles for each function with different parameter combinations used in AAC.
I find it difficult to predict the performance for a stream based on these)

HI.
Also can any body tell me the memory requirement of IPP AAC such as
code size, table size, scratch/persistence size.

Hi Prateek,

Intel IPP sample has got Audio and Video Coding samples which supports AAC format. You can use this sample to measure the performance of any stream data.

Also you can refer to AAC codec folder to get an idea about code size.

Thanks,
