Extrcting features with opencv

[nidhijoshi123]

Thanks for the software!

I am getting the following error when I provide the audio visual input:

(ERR) [0] commandlineParser: parse: unknown option '-P' on commandline! (ERR) [1] cComponentManager: cannot add component (instname='openCVSource' type='cOpenCVSource'): unknown component type!! (ERR) [1] cComponentManager: error during addComponent (returnVal=-1)!

Can you please help ? Do I need to externally download some models ?

This indicates that openSMILE was not built with OpenCV. The pre-built binaries made available via GitHub do not include OpenCV, you will have to build it yourself. See https://audeering.github.io/opensmile/get-started.html#compiling-on-linux-mac-with-portaudio-and-opencv-support and https://audeering.github.io/opensmile/get-started.html#compiling-on-windows-with-portaudio-and-opencv-support in the documentation.

openSMILE does not come with any models for audio-visual analysis and it is also not possible to run models as part of openSMILE. You can only use openSMILE to extract features. Note that visual feature extraction in openSMILE is extremely limited, as the focus for openSMILE has always been on audio feature extraction.
