First, the latest DeepStream 5.0 GA is available. Please upgrade to the latest version.
There is no timestamp information in your “ch00.h264” file so it can not be use alone as the qtmux input.
Our test h264 file can.
gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepsteam-5.0/samples/s
treams/sample_720p.h264 ! h264parse ! nvv4l2decoder ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=tmp.mp4
Our suggestion is to use our DeepStream plugin nvstreammux, it is also a must when you construct deep-learning pipeline.
