I tried installing the hardware-accelerated ffmpeg working for the Jetson, available here: https://github.com/jocover/jetson-ffmpeg
I have gotten this working before, but now when I try and run the cmake, I get this error:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: LIB_V4L2 linked by target "nvmpi" in directory /home/tombert/jetson-ffmpeg -- Configuring incomplete, errors occurred! See also "/home/tombert/jetson-ffmpeg/build/CMakeFiles/CMakeOutput.log". See also "/home/tombert/jetson-ffmpeg/build/CMakeFiles/CMakeError.log".
Is there some library that I need to install?
