Hello,
I'm trying to composite multiple video files into a single video file using GStreamer and RPI 4 using v4l2 hardware accelerated plugins. Currently, it's not work. I've a simple test pipeline below that is halting with some warning. Anyone have an idea or has tested this before?
pipeline (video.mp4 was generated with videotestsrc 1920x1080 encoded as h264):output (pipeline halts not much of an error):Thanks a bunch.
