H265 video decoding pipeline for Orin benchmarking

hi ,

on the datasheet https://www.nvidia.com/content/dam/en-zz/Solutions/gtcf21/jetson-orin/nvidia-jetson-agx-orin-technical-brief.pdf
for video decode , for h265 ,the total stream density is 18x 1080p30 (H.265) , may I know how to reproduce this data ? can you show the full pipeline on gstreamer ?

Hi,
Please run the command:

$ gst-launch-1.0 -v videotestsrc num-buffers=300 is-live=1 ! video/x-raw,width=640,height=480 ! nvvidconv ! 'video/x-raw(memory:NVMM),width=1920,height=1080' ! nvv4l2h265enc maxperf-enable=1 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 &

into 18 processes. And check frame rate of each process.

hi ,
do you have the pipeline for decoder ?

Hi,
Please try the command for hardware decoding:

$ gst-launch-1.0 -v filesrc location=/opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h265.mp4 ! qtdemux ! h265parse ! nvv4l2decoder enable-max-performance=1 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 &

The video file is in DeepStream SDK. If you don’t install the package, please use either video file in 1080p H265.

hi ,
is there any way to run “looping” continuously in this pipeline on the mp4 video source ?
thanks !

Hi,
Please try to enable the property in multifilesrc

Not sure if it works as your expectation. May give it a try.

hi ,
we ran the pipeline on the Orin 32GB , but manage to get 38 stream density . why there are so huge difference compare to your published spec?

we found the swap is 32gb , physical memory is 32gb , any impact on stream density if we change the swap spaces ?

Hi,
We would suggest follow the spec in module data sheet. The data is guaranteed throughput when using AGX Orin series.

hi
we are using the Orin spec , but we can not reproduce the number of stream density on the following pipeline , we can get close to 40 streams

hi,
what’s the configurations on Orin 64GB and pipeline gst command used in order to get 22 as the maximum stream density for 1k 30fps video and 7 as the maximum stream density for 4k 30fps video?

Please open a new topic for your issue. Thanks
