The following section describes some relevant performance measurements during video stabilization for a few standard resolutions. It begins with a summary of the results detailed on the following sections, as well as the pipelines used to capture such results.
Summary
Benchmarking
Standalone element
Pipeline
All the measurements bellow where made using the following minimal pipeline.
PATH_TO_FILE=path_to_file.rgba WIDTH=1920 HEIGHT=1080 FRAME_SIZE=$(($WIDTH * $HEIGHT * 4)) gst-launch-1.0 filesrc location=$PATH_TO_FILE blocksize=$FRAME_SIZE ! videoparse format=rgba width=$WIDTH height=$HEIGHT ! nvstabilize ! fakesink sync=true

Resolution | CPU 0 | CPU 1 | CPU 2 | CPU 3 | CPU4 | CPU5 | Average (reported by top) |
---|---|---|---|---|---|---|---|
640x480@25Fps | 0.52 | 11.6 | 18.54 | 0.14 | 3.61 | 0.71 | 21.9 |
1280x720@25Fps | 4.7 | 49.3 | 40 | 1.28 | 12.5 | 1.21 | 38.2 |

Glass-to-glass latency
Latency was measured as shown in the picture, and the following are the approximate results. It is important to notice that latency can be affected by the parameters selected on the pipeline, specifically the queue-size property of the gst-nvstabilize element, as further explained on the User Guide. The pipeline used was the following:
gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw,width=1280,height=720' ! nvvidconv ! 'video/x-raw(memory:NVMM),width=1280,height=720,format=RGBA' ! nvvidconv ! queue max-size-buffers=1 leaky=downstream ! nvstabilize queue-size=5 ! nvvidconv ! nvoverlaysink sync=false
