Hi, I have trouble streaming image frame data.
The information of frame are,

  • Size : 7936x32
  • Frame rate : 1000fps
  • Pixel format : RAW8

I made sensor driver and when I used v4lt-ctl, I got some errors like below.

I wonder that there are constraints of image width and frame rate in L4T (version 32.2.3).

What kind of sensor can output such big size @1000fps?

Get the trace log to check if can get more information.

I’m trying to bring up DVS(Dynamic Vision Sensor).
And now, I’m setting the frame rate to 30fps and if OK, I’ll try to set 1000fps.
I’ll check the information you gave and if more question, add reply.
Thanks.
