I am making fullHD camera recording using Gstreamer.
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 SUM MMDC new Profiling results: *********************** Measure time: 501ms Total cycles count: 264461184 Busy cycles count: 216280018 Read accesses count: 7991244 Write accesses count: 6424326 Read bytes count: 133236928 Write bytes count: 140699808 Avg. Read burst size: 16 Avg. Write burst size: 21 Read: 253.62 MB/s /  Write: 267.83 MB/s  Total: 521.45 MB/s Utilization: 7% Overall Bus Load: 81% Bytes Access: 19

Is this load condition reasonable?

I apologize for the delay

Which i.MX are you using? Are you using the i.MX6Q?

Best regards,

Diego.
