Please re-run the gstreamer pipeline with `ARV_DEBUG=all`.

Try `gst-launch-1.0 aravissrc ! video/x-raw,format=GRAY8 ! videoconvert ! autovideosink`

`arv-tool-0.8 features PixelFormat` ?

Gstreamer videoconvert element does not take bayer formats as its sink. You have to insert a bayer converter, something like: ``` gst-launch-1.0 aravissrc ! video/x-bayer,format=rggb ! bayer2rgb ! videoconvert !...

Oh, I did not see you were using aravis main branch. Please use the latest stable release, 0.8.30.

We have something like that in Aravis, only used in GvDevice, and with no user API yet. https://github.com/AravisProject/aravis/blob/0df6d6aa9eb54454ac821c8db5e58a02a5e5f2a4/src/arvgvdevice.c#L1310-L1348 A properly designed user API would be interesting.

Like `control-lost` signal ? https://github.com/AravisProject/aravis/blob/0df6d6aa9eb54454ac821c8db5e58a02a5e5f2a4/src/arvcameratest.c#L655-L656 This signal is not documented yet, and we should provide a ArvCamera helper.

I understand the need and agree #709 is not enough. That will not happen by itself though.

HI @wuhaochen , did you have a chance to work on this issue ?

Hi Brian, Could you check you actually receive a discovery acknowledge packet using wireshark ? Did you try the `--gv-allow-broadcast-discovery-ack` option ?
