AM572x mpeg4 encoder

Natalia Girfanova11

Hello,

I am trying to access mpeg4 encoder on am572x. I've included #videnc2.h and #impeg4enc.h files in my c-code for arm processor and call there VIDENC2_process function. But during compilation I have an error - underfined reference to VIDENC_process. I don't have any appropriate lib files in installed sdk. What should I do to exploit the inbuilt encoding facilities?

Thank you.

Hello,

Yes, thank you, I've already found and used this example.
Particular I use the part for mpeg4 encoding and the problem is VIDENC2_process function (line in example 1347) produces an error - "underfined reference" during compilation, though all header files are included.

Regards,

Natalia

You need to link with userspace library libdce.so . This has references to VIDENC2_process()

Linking to libdce.so produces an error - attempted static link of dynamic object. I need static lib, can I generate it from this: https://git.ti.com/ivimm/ipumm/trees/master ?

Hi,
libdce source is available in git://git.omapzoom.org/repo/libdce.git , do you have yocto filesystem to build
What you are trying is dce framework for IPU2 remote core.

Hello,
Thank you.
The problem is I have Linux like shell, not Linux, on the arm core, very similar to fs_shell_app_utils.c in image processing demo from processor_sdk_rtos_am57xx_3_00_00_04.
Do you think, will libdce library compilated directly to my project as static lib operate correctly?
