This seems to be a recurring problem on the forum that the avenc_mpeg4 plugin cannot be found. Followed all the instructions for installation of DeepStream 6 SDK on Jetson Nano last week. Ran into this missing plugin issue when we are attempting to run the deepstream-opticalflow.py sample. We reflashed the system and repeated the steps. Same issue. Clearing the cache does not resolve the issue either. Reinstalling the libav plugin just tells us it is already installed. What are we doing wrong?
