At this time, the problem that the frame rate does not come out in Full HD recording has occurred.(May be about 5fps)
I am connecting 16 bit gated mode CSI camera.
I am remodeling imx-4.9.88-2.0.0_ga for this camera and using it.
I am using gstreamer on the pipeline below.
$gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! \
videorate ! "video/x-raw,framerate=30/2" ! \
imxvideoconvert_ipu ! video/x-raw,format=NV12,width=1920,height=1080 ! \vpuenc_h264 bitrate=15000 ! mpegtsmux ! filesink location=output.ts
I checked the bus situation at this time using the MMDC Profiling Tool and found that the bus load was high.
MMDC new Profiling results:
Measure time: 501ms

Is this load condition reasonable?
