Imx8mm vpu libimxdmabuffer compile error

[hello122344]

Hi, I'm working with  iMX8mm   i want to use  vpu H264

https://github.com/Freescale/libimxdmabuffer

When following the specified configuration instructions;

./waf configure --prefix=PREFIX

Errors relating to not having a specified kernel headers path appear. So I added the following kernel headers path in the configuration;

./waf configure --prefix=PREFIX --imx-linux-headers-path=/home/jensen/imx8mm/OK8MM-linux-sdk/OK8MM-linux-kernel/include/  

but  Errors  Could not find linux/mxcfb.h in path "/home/jensen/imx8mm/OK8MM-linux-sdk/OK8MM-linux-kernel/include/" specified by --imx-linux-headers-path   But there is linux/mxcfb.h  in this directory

Any suggestions on what could be causing this issue?

Thank you,

jensen

why do you need to install this if you just want to use vpu encoder? the bsp support vpu encoder already as default, you don't need to install this, this isn't official released version, I'm not sure if this is tested on imx8mm board

hi ,joanxie

Thank you for your reply.

I want to decode USB camera(H264) with vpu,I found libimxvpuapi      https://github.com/Freescale/libimxvpuapi

But libimxdmabuffer is required when compiling

Checking if this combination works : yes
Checking for program 'pkg-config' : /opt/fsl-imx-xwayland/4.14-sumo/sysroots/x86_64-pokysdk-linux/usr/bin/pkg-config
Checking for 'libimxdmabuffer >= 0.9.0' : not found
The configuration failed

Do you have vpu api for imx8mm? Or how to use vpu of imx8mm(usb camera)

think you very much..

Best wishes
