i have tried both the deepstream-test1 from python samples and and a config from retinanet-examples
here

i tried an mp4 video and the same video converted to h264 using mpeg:
ffmpeg -i output.mp4 -an -vcodec libx264 -crf 23 outfile.h264

in both cases i get the following video decode errors

python app deepstream_test_1.py video_path.mp4

i installed the NVIDIA V4L2 GStreamer plugin from the getting started page and i am quite sure it is correct

i have no clue if my video is the cause of the error or some setting/installation issue, is there a easy way to check whether my video has right encoding?

thanks in advance

Hi,
You can test your video with gst-launch:

GST_DEBUG=2 gst-launch-1.0 uridecodebin3 uri=file:///home/nvidia/video.mp4 ! queue ! nvoverlaysink sync=false

thanks! my mp4 file was not working because of codec reasons
