Kurento has lots of examples of writing kms-filter modules that process video frames, but none that show how to process audio+video. Additionally, kurento-module-scaffold.sh seems to only generate module projects that receive a cv::Mat or a GstVideoFrame.
Kurento itself says
As a differential feature, Kurento Media Server also provides advanced media processing capabilities involving computer vision, video indexing, augmented reality and speech analysis.
so it seems like it should be possible, but I can't see any way to get at the audio in their API.
So my question is: can this be done? If so, how?
