gstreamer frame skip

y-iijima-emb — Mon, 04 Oct 2021 08:54:59 GMT

Hello,

I am using IMX8MM-EVK with the MINISASTOCSI accessory and work it with Linux 5.10.35_2.0.0. When I input the command as below, I am getting kernel message : "skip frame 1" once.

gst-launch-1.0 v4l2src device=/dev/video0 ! waylandsink

It means that drop frame occured？ No kernel message shows when I capture image with v4l2-ctl.

Hi @y-iijima-emb

Can you follow the user guide to gst test?

Hi nxf65025,

I tried gst test according to the user guide : Section 7.3.8 Camera preview, kernel message : "skip frame 1" was showed as ever. Test command is as below.

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=(string)YUY2,width=640,height=480,framerate=(fraction)30/1 ! autovideosink

I'm trying to port the camera sensor(IMX226) that supports external trigger in the future. Before that, I would like to confirm that showing "skip frame" message does not mean frame drop.

Thanks

@y-iijima-emb

"skip frame 1 " message does not mean frame drop.This is normal.
