Hello,
it seems that it could be related to PixelFormat in the camera configuration. Could you please check with Pylon Viewer Basler application which configuration this parameter has?
The following code snippet seems to produce an exception:
if ( GenApi::IsAvailable(cam_->PixelFormat) )
{
GenApi::INodeMap& node_map = cam_->GetNodeMap();
GenApi::CEnumerationPtr(node_map.GetNode("PixelFormat"))->FromString(gen_api_encoding.c_str());
}
Also, can you check if the camera starts already automatically grabbing?
Thanks!

Hi @MomoHsieh ,
generally speaking, when StartGrabbing() is called once, all critical parameters that may change the buffer payload size (Pixel Format, Width, Height, etc.) become locked, i.e. RO.
Thus, when trying to set e.g. Pixel Format after StartGrabbing(), this will always result in an exception.
Thus, setting Pixel Format can only be done after calling StopGrabbing().
