@CodeLogist Maybe It have some new problem with gst. There is a conflict between ffmeg and libpaler. They both need to overwrite the same files. If you install ffmpeg with --force ,then you will lose libplayer. This leads to gst problems . If I don’t install ffpeg, I can use cheese with my webcam. I don’t have a same webcam with you .So you can try it ,but maybe have some problems.
