Thank you for showing URL.
I followed the FAQ and ran deepstream-test5-app with 15FPS and 30FPS video files as input, but found that frames drop in the output video.
I followed the documentation below and set max-latency to a value greater than 1/FPS of the slowest stream, but the frames still drop.
Why do the frames drop ?

https://docs.nvidia.com/metropolis/deepstream/6.0/dev-guide/text/DS_plugin_gst-nvstreammux2.html#observing-video-and-or-audio-stutter-low-framerate
I run this command in the docker container.
command
cd /opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/deepstream-test5/configs
mkdir /output
cp path/to/sample_1080p_h264_15fps.mp4 /output/ # copy sample_1080p_h264_15fps.mp4
vi test5_config_file_src_infer.txt # edit
vi config_streammux.txt # make nvstreammux configuration file
USE_NEW_NVSTREAMMUX=yes deepstream-test5-app -c test5_config_file_src_infer.txt
