|
|
I have replaced my laptop from 2011 by a current model (Dell XPS 15 9550).
I am not familiar with having two graphics cards, so maybe my problem is related to it. The NVIDIA info shows UFOCaptureHD is not using it, anyway (seems only 3D applications can? Or can I disable Intel HD 530 device to force using it?)
When I start the capture, a video frame shows and then this part of the screen goes black or stays displaying this frame without time stamp. It does detect and save videos correctly.
Only when I let the laptop turn off the screen temporarily and then touch the mouse to turn it on, the video stream and time stamp shows properly. Has anyone experienced this before and solved it?
Note it runs fine with my internal webcam, but not my b/w USB 3 camera.

Is it also new ?
Sounds the camera or capture device causes the problem.

No, the camera is the same as I used before without problems on the previous system. But on this system the stream displaying is a problem, while UFOCaptureHD does detect something and captures good video. Maybe I should try with my older version of the program which I ran on my previous laptop?

Oh, something got solved by itself! I was messing in camera settings, switched to RAW format, it crashed UFOHD, I switched back to Mono8, ran UFOHD and it displayed the stream. I have no clue how! Hope this does not come back to haunt me during observing nights

The problem returns after reboot/return from sleep. I found a method which seems to work consistently:
- Plug the camera in a USB 3.0 port.
- Open FlyCap2 to stream video.
- Run UFOHD and try to preview the stream (it will only say: Activating)
- Quit UFOHD and FlyCap2
- Start UFOHD again, preview the stream now works fine.
Without software from the manufacturer trying to stream simultaneously with UFOHD for a moment (it produces a streaming error in that software), the stream would remain black in UFOHD. I am not sure how it works, probably a Microsoft usbxhci driver quirk, but I can now use the camera normally again

Just to report that my issue has finally gone after I installed version 4.24 of UFOCaptureHD2 and version 2.11.3.121 of FlyCapture (from Point Grey, now FLIR) this weekend! Makes observing a whole lot more enjoyable.

No!! It was temporary luck again.
I also got GraphStudioNext tool to check the video stream. It displays video right away when connecting Point Grey camera source to a Video Mixing Renderer.
It loads with the default media subtype, which turns out to be RGB32, and displays the stream.
However, if I actively choose a subtype, even RGB32, it gives an error, and subsequently I do not get a list of types again, and also gives an error choosing the default. Maybe this is related to what happens in UFOCaptureHD2?

Hi SonotaCo,
Just an update because I have a new laptop (Asus ProArt Studiobook 16 v2021)
It still has this issue where the live screen is black but sometimes comes back to live. Using all the latest software. Maybe the DirectShow driver was better in a past version of FlyCapture.
This was also the case on an old laptop from 2007 where I installed Windows 7 and used latest software.
Another issue is now the captured video files also do not always want to play in UFOCaptureHD. Surely that is not a camera driver issue. I am using the Lagarith codec, no problems before, but probably something in Windows 10/11 causes it. It also occurred on the HP laptop with Win10 and Intel UHD Graphics.
Any ideas?
Oscar

Hi Oscar
Thanks for the report. We've known each other for a really long time. Congratulations on getting a new PC.
Sorry I can only investigate the phenomena reproduced on my PC, I will try the Lagarith codec later and report the results.

The result of Lagarith codec with UFOCaptureHD2 is below.
1920x1080/30p by Ryzen 3700X --> OK
4096x2160/59.94p by Ryzen 5800X --> NG
It seems the cause was insufficient CPU power per thread.
As for lossless codec, We have tested Ut video codec suite - YUV422 below, and got good results.
It was OK for 4096x2160/59.94p by Ryzen 5800X

This might be worth to test.

Hi SonotaCo!
I will try it. I used Lagarith since 2014 because of its lossless compression and low CPU load. I am curious for the performance and quality of Utvideo codec. I hope it solves my issue. Even after a reboot, videos do not play back in UFOCapture.
Yes, we know each other for a long time! I hope you are doing well. Our meeting in Tokyo, with Harald, in 2009, was very nice! I only returned to Japan in 2018, for the ICAE conference in Nara. I even felt a M5 earthquake
I used UFOCapture to trigger an intensified high-speed camera during my gigantic jet campaigns in Colombia in 2017-2018, converting the audio output to a 5V signal.
You can see the results here: https://www.nature.com/articles/s41467-019-12261-y
In the last few years our Facebook group "International Observers of Upper-Atmospheric Electric Phenomena" has grown a lot, some of you may be interested in joining: https://www.facebook.com/groups/376355972487572
We sometimes see some events from this forum shared in that group!
A question: Do you know if Japanese observers detected the "green ghost" on the tops of some red sprites yet? It mysteriously does not seem to show up in monochrome video (no lasting glows as far as I can see).
Oscar

No, I've never heard of it. Yes, it may very exciting to chase ghosts...
As for Blue Jet I have a new idea recently that I would like to discuss with you all sometime.

Looks good in my test. I attach a sprite of last Friday (1 frame at 50 fps, with moonlight)
However, it did not solve my capture stream not showing, and I still cannot play the videos UFOCaptureHD.
It seems an operating system or software issue, because when I let the laptop fall asleep and then wake it, sometimes the video stream is visible again. I got the video stream issue already perhaps since 2016 on different systems. But the replay issue occurred only more recently. Perhaps I can try an older version of UFOCaptureHD to check it.

Update:
I was able to test video replay in older versions of UFOCaptureHD2:
4.20 (2016): works
4.24 (2017): works
4.54 (2020): does not work
4.66 (2022): does not work
The replay test used UtVideo codec, recorded with UFOHD2 version 4.66.

Thank you for report. I
Could you test a beta version below?
You may need to run Microsoft's latest redistribution module installation (VC\redistx86.exe)
