Getting Errors on arv-device-test - dont know where to start solving

Using Aravis
1

Hello all,

I am fairly new here. Also new to Aravis, IP camera and actually Linux/Raspberry Pi - nevertheless, I managed to install Aravis on my Pi. It also seems to work so far. However, I get an error message in the ./arv-device-test and don’t know exactly where to start. The arv-viewer-0.8 does also give me errors. Does anyone have a tip for me?
I think it could be a configuration/settings problem, but bot sure about that and how to solve it.

Hi,

Welcome here. Thanks for your interest in Aravis !

That is a lot, 12MB for each image. What version of raspberry pi are you using ? What is its network bandwith ?

You probably have a lot of missing packets. Try to run arv-camera-test-0.8 instead of arv-device-test, it will show you some statistics about the data transfer.

You may want to reduce the image size, or frame rate. Have a look at the performance related documentation: Aravis – 0.10: Ethernet Devices

Is it a 1000 Mbit connection or more?
If its “ONLY” 1000 Mbit (1000BASE-T) you seem to be trying to push more frames than the network can handle.
Make sure you are running jumbo frames on your network device at max and have the same size in your genicam camera setting. Or if the network/camera can handle it, Use 2.5GBASE-T or better . See if test changes.
Looking at the payload size its 16bits per pixel.
It may be possible to send the frames as Bayer 12bitPacked instead that way you will possibly increase the framerate with some 30%…
Sometimes there is a camera setting for “RESERVED” bandwith not being used. If its decreased your actual framerate might go up.

Hello,
thanks for the suggestions. The problem was, as you suspected, the package size was too big. I reduced the resolution and now I get pictures. Thank you!
