Unable to install/build/run hyperflut

[picky33]

no matter what I try it doesn't seem to want to install. I keep getting this error:

"The following warnings were emitted during compilation:

The system library gstreamer-video-1.0 required by crate gstreamer-video-sys was not found.
The file gstreamer-video-1.0.pc needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
The PKG_CONFIG_PATH environment variable is not set.

HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing gstreamer-video-1.0.pc.

I tried to install gstreamer using the instructions on https://gitlab.freedesktop.org/gstreamer/gstreamer-rs#getting-started but it still got the same error. not sure what i am doing wrong

[germanVCB]

Please show the console output command: find sudo find /usr -name "gstreamer-video-1.0.pc"?
and copy the path to this file to the environment settings
export PKG_CONFIG_PATH=/usr/lib/pkgconfig:$PKG_CONFIG_PATH

[picky33]

Output is: ubuntu@ubuntu:~$ sudo find /usr -name "gstreamer-video-1.0.pc" /usr/lib/aarch64-linux-gnu/pkgconfig/gstreamer-video-1.0.pc

i'm not sure if i'm setting the environment settings correctly
even if i set the path by running this code is still get the same error export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/lib/aarch64-linux-gnu/pkgconfig/gstreamer-video-1.0.pc
