SHORT_FRAME issue cause crash in nvarguscamerasrc but issue does not appear with v4l2

Hi all,

I have been debugging an issue with nvarguscamerasrc in JP4.4.

I am moving a servomotor through i2c, this motor is totally independent of the cameras.

The issue comes up when I capture from the camera using nvarguscamerasrc and then I move the motor.

This issue does not happen with capturing with v4l2-ctl, and also it does not happen using nvcamerasrc and JP3.2.1. The issue started to appear when we did the porting to JP 4.2.2 and it is still happening with JP 4.4.

enabling the trace for checking the nvarguscamerasrc failure when moving the motor:

I am also seeing the SHORT_FRAME message in the debug messages for nvargus-daemon.

With v4l2-ctl there are no issues when capturing and moving the motor, on the trace everything goes correctly.

I also added debug to the TX2 capture subsystem it seems that V4L works different as nvargus does, I see messages from the capture subsystem of each buffer dequeued using V4L but for nvarguscamerasrc I do not see any message from the capture subsystem it only starts the stream.

It seems like nvargusdaemon handles the dequeue method when using nvarguscamerasrc to dequeue buffers, is that right?

Do you know what can be causing this issue?

Thanks,

Hi,
Would like to know if the issue is specific to using gstreamer. Could you try the jetson _multiemdia_api sample?

/usr/src/jetson_multimedia_api/samples/09_camera_jpeg_capture

Hi DaneLLL,

I have tried that sample and the same issue appears.

Thanks,

It’s could be the sensor gain/exposure/frame rate control function do something cause the short frame error. You may try to modify the sensor driver to have those function as dummy to check it.

Hi ShaneCCC

I did the test you mentioned with dummy gain/exposure/framerate controls but the issue appeared. I also set the gain and exposure to the minimum camera value supported (both gain and exposure), also to the maximum but no success.

It is interesting that with v4l2-ctl the issue does not appear. there are no issues on the vi trace when using v4l or using nvcamerasrc neither (JP 3.2.1).

Thanks,

Can you try to modify the active_h in device tree to narrow down it.
