Hi,
I am new to this forum. I work in a company to make video capture card.
I need to do YUV422 resize with IPP in linux kernel module for freeware application. I will post my code and Makefile.
In IPP 8.1, I can succeed to use ippsGetLibVersion(); and ippsSum_16s_Sfs().
However, ippiResizeYUV422_8u_C2R(), ippiResizeYUV422Nearest_8u_C2R(), ippiResizeYUV422Linear_8u_C2R() all with link error, such as "floor. undefined!" ( it seemed to be a function call in application layer).
In Oneapi Basekit 2021.03, my code got worse, with link error "ippInit(); undefined!"
All system information are in Makefile (OS version , kernel version, gcc version ...)
Any help will be grateful!

Hi,
Thanks for reaching out to us.
>>ippiResizeYUV422_8u_C2R()
This function is not supported in the current version(2021.3.0) of IPP
For more details please refer to the below link:
>> with link error "ippInit(); undefined!"
To remove this linking error, you can try linking the library files to your command.
-I $IPPROOT/include -L $IPPROOT/lib/<arch> -add the necessary library files(you can get that from document of required function)
For example:
icc *.c -o ipptest -I $IPPROOT/include -L $IPPROOT/lib/ia32 -lippcore -lippvm -lippi -lipps
>>I need to do YUV422 resize with IPP
We are looking into it. We will get back to you soon
Thanks & Regards
Noorjahan.

Peter,
ippInit API is available in the current version of IPP 2021.3. You may check ippcore.h.
ippiResizeYUV422_8u_C2R() -
// This API has been removed and is not available. See IPP Reference Manual Appendix C: Removed Functions for Image and Video Processing
// There is no replacement.
ippiResizeYUV422Nearest_8u_C2R() - available into version 2021.3
ippiResizeYUV422Linear_8u_C2R() - available into version 2021.3
I sligtly modify your original example ( see main_mod.c file) and compiled and linked against
IPP 2021.3:
icc -I/opt/intel/oneapi/ipp/2021.3.0/include main_mod.c -o 3.x \
/opt/intel/oneapi/ipp/2021.3.0/lib/intel64/nonpic/libippi.a \
/opt/intel/oneapi/ipp/2021.3.0/lib/intel64/nonpic/libipps.a \
/opt/intel/oneapi/ipp/2021.3.0/lib/intel64/nonpic/libippcore.a
The compilation was successful.
both of ippiResizeYUV422Nearest_8u_C2R() and ippiResizeYUV422Linear_8u_C2R() functions as well as ippInit were called and compiled.
The runtime has not been checked. as it is out of the scope of this thread.
