Preview not working #359

Closed EricClaeys closed 3 years ago

EricClaeys commented 3 years ago

I have a ZWO 178MC and when "Preview" is set to "1", the allsky program gives an error: Unable to init server: Could not connect: Connection refused

It fails in the Display() function at the call to cvShowImage("video", pImg); All calls to ASIGetVideoData() also fail with return code 13 (buffer too small), pRgb.step[0]=9288, and pRgb.rows=0.

If I start the program by ./allsky.sh I get this error: OpenCV Error: Bad flag (parameter or structure field) (Unrecognized or unsupported array type) in cvGetMat, file /build/opencv-L65chJ/opencv-3.2.0+dfsg/modules/core/src/array.cpp, line 2501 terminate called after throwing an instance of 'cv::Exception' what(): /build/opencv-L65chJ/opencv-3.2.0+dfsg/modules/core/src/array.cpp:2501: error: (-206) Unrecognized or unsupported array type in function cvGetMat

Any ideas?

Laheller, I was never able to figure this out. The preview feature works in the ZWO "demo" program that comes with their SDK, although its code is somewhat different. I don't know enough about the CV code to be able to debug it.

Bbillp, I see your post asking where the messages come from. I assume at some point you responded to a message on this thread, or subscribed to it, so GitHub is now sending you emails when there is an update.

Is this mail list a substitute for posts on allsky at github because my posts there don’t come up in these emails. Today are my first posts in a couple of years so i missed a lot of info.

Closing issue. preview doesn't work over VNC viewer. It DOES work when logged in directly to the Pi.

@EricClaeys No, it does NOT. At least on my RPI it throws the same error as above even when logged in directly.

EricClaeys commented 3 years ago

@laheller, let me check on my Pi when logged in directly. It used to work so if it doesn't now then something broke it.

This is likely related to PR #507

NOTE: I had quite a bit of issue getting the Display() function to compile, but finally got something workable -- although, I've not tested the Display capability. I would love for someone to test the Display code prior to merge. Otherwise, the rest of the code compiles fine on both Raspberry Pi OS based on Debian Buster with OpenCV 3.2.0, as well as Debian Bullseye with OpenCV 4.5.1.

Closing this issue - is being tracked via Issue 395.
