Hi,
By default we have verified single 4Kp60. Please refer to developer guide
For multiple decoding sections, you can run like:
$ gst-launch-1.0 -v filesrc location="/home/nvidia/bbb_sunflower_2160p_60fps_normal.mp4" ! typefind ! qtdemux ! multiqueue ! h264parse ! nvv4l2decoder enable-max-performance=1 ! fpsdisplaysink video-sink=fakesink sync=false text-overlay=0 filesrc location="/home/nvidia/bbb_sunflower_2160p_60fps_normal.mp4" ! typefind ! qtdemux ! multiqueue ! h264parse ! nvv4l2decoder enable-max-performance=1 ! fpsdisplaysink video-sink=fakesink sync=false text-overlay=0
The sample command has two decoding sections. You may try other cases and ensure each section achieves target fps.
For multiple decoding sections, please set enable-max-performance=1 to disable DVFS of NVDEC.
