I tested the fake camera with different pixel formats and noticed that the transfered images look not ok.

**MONO8**

So, only MONO8 is working properly.  
Am I using the camera wrongly or is it a bug?

Hi,

The fake device is mostly a debugging tool for Aravis itself, not really intended to be used with another vision stack. That being said, what you are seeing is may be indicating aravis is doing something wrong. Please open an issue on github: [https://github.com/AravisProject/aravis/issues](https://github.com/AravisProject/aravis/issues).

Thanks,

Emmanuel.
