Hi ,

Could you please assist with the following. Currently successfully viewing live streams from a a JAI BM-500GE via the arv-viewer-0.8 but when I try to use the simplest GStreamer command the above topic error occurs.

GStreamer Command : ARV_DEBUG=all ./gst/gst-aravis-launch aravissrc ! videoconvert ! ximagesink is giving the following output:

ARV_DEBUG=all ./gst/gst-aravis-launch aravissrc ! videoconvert ! ximagesink

I’m afraid I am struggling to understand why the same error is not being picked up by the arv-viewer.

Hi Les,

I guess that is because the gstreamer plugin tries to set the camera framerate, where arv-viewer only sets the framerate on user action.

Looking at the code, it seems this camera does not have a AcquisitionFrameRateAbs feature neither a AcquisitionFrameRate one. Could you open a new issue on github about JAI BM-500GE support, and attach to this report the output of arv-tool-0.8 features ?

Thanks.

Emmanuel.
