Hi,

I'm In the process of adding v4l2h264dec or imxvpudec

v4l2h264dec was not able to add. so i tried imxvpudec using the repo https://github.com/Freescale/gstreamer-imx

but the dependencies libimxdmabuffer not installing which is saying

--imx-linux-headers-path is not set

if i set the path then its giving

Could not find linux/mxcfb.h in path

how to resolve this ?

is this procedure for running os or cross compilation?

and what are these path ?

CC
CFLAGS
LDFLAGS
PKG_CONFIG_PATH
PKG_CONFIG_SYSROOT_DIR

please give me the detailed information

thank you

You don't mention which kernel you're using. You'll need a kernel with the i.MX additions. For instance I'm in the middle of updating to 5.15-2.0.x-imx. mxcfb.h is under include/uapi/linux and will be installed if you use make install_headers or a build system that packages that.

As @dougnazar explained, you need an imx-kernel. That said, recently, I am now moving away from checking for mxcfb.h, since some sysroots don't package this anymore. libimxdmabuffer's latest version (1.1.3) no longer checks for it; libimxvpuapi will follow soon. But you still need to specify the path to the imx headers, since libimxdmabuffer needs to use the IPU and PxP headers for the corresponding allocators to work.
