[BUG]: DSLR Liveview not working (cameracontrol.py) #527

Closed r07aNd closed 4 months ago

r07aNd commented 10 months ago

Describe the bug

Hello,

first of all thank you for the great work. I installed a brand new Rasperry Pi 5 and installed Photobooth with the installation script. I am working directly on the Raspberry with a display. I changed the following settings in admin panel to enable preview with Canon EOS 60D:

Live preview -> Preview mode from: None to: from device cam (no remote preview)

Live preview -> Use preview from device cam as background from: Off to: On

Commands -> Execute start command for preview on take picture/collage from: On (default) to: Off

Commands -> Command to generate a live preview from: to: python3 cameracontrol.py

Commands -> Take picture command from: gphoto2 --capture-image-and-download --filename=%s to: python3 cameracontrol.py --capture-image-and-download %s

The following commands are working standalone in terminal:

If I open Photobooth via http://localhost/ the shutter is opening, but I only see the standard background of Photobooth. If I press the picture button to take a photo, the counter starts ending with the Cheeeeese message (stucks there without taking a picture). If I want to open http://localhost/ in a second browser window, Photobooth is not responding anymore.

Is there something else I could do?

Thank you!

Hey and thanks for the report!

I am aware of the issue, but yet didn't hat enough time to look at it. To workaround that please add the following lines to /usr/ffmpeg-webcam.sh

sleep 5
python3 /var/www/html/api/cameracontrol.py -b

(The -b is optional, remove if you set Execute start command for preview on take picture/collage to off)

Edit: Workaround not possible anymore. Modules loaded via systems now: https://github.com/PhotoboothProject/photobooth/pull/557

r07aNd commented 10 months ago

Hi,

thank you for the hint, but unfortunately it is not solving the problem. When I now start the Raspberry without accessing the the Photobooth application the shutter opens already (assuming this is because the service is started already?). When I open Firefox at http://localhost a small icon appears informing that a video is played in Picture-in-Picture mode. When I press on this small icon I only see black screen any video stream from the camera. When I press the picture button the countdown is triggered and a picture is taken. Liveview is unfortunately still not working.

I have added the following lines to /usr/ffmpeg-webcam.sh sleep 5 python3 /var/www/html/api/cameracontrol.py

What's your preview config? Same on Chromium?

This workaround is working for others. Any other cameras connected?

Maybe also try without using it as background using -b and starting preview on take picture/collage.

r07aNd commented 10 months ago

Hi,

I just tested with Chromium and it works with Chromium - THANK YOU!

Besides the standard / default configuration after installation with the install script, I did the following changes:

Live preview -> Preview mode from: None to: from device cam (no remote preview)

Live preview -> Use preview from device cam as background from: Off to: On

Commands -> Execute start command for preview on take picture/collage from: On (default) to: Off

Commands -> Command to generate a live preview from: to: python3 cameracontrol.py

Commands -> Take picture command from: gphoto2 --capture-image-and-download --filename=%s to: python3 cameracontrol.py --capture-image-and-download %s

As workaround add the following lines to /usr/ffmpeg-webcam.sh (works only for Chromium) sleep 5 python3 /var/www/html/api/cameracontrol.py

I have no other cameras connected.

For Firefox it does not work - here some screenshots maybe they will help to analyze further.

After pressing the small picture-in-picture icon it looks like this with Firefox

Access was granted inside Firefox?

r07aNd commented 10 months ago

Yes permissions for camera usage has been granted within Firefox

Could you please disable PIP and try again?

r07aNd commented 10 months ago

I have now reset all firefox settings and tried again without success and have reset again all settings and disabled PIP with the same result for Mozilla Firefox 121.0 (64-bit) for Raspberry Pi OS, which was part of the installation image of the Raspberry PI.

I installed now in addition Firefox ESR (Extended Support Release) version 115.6.0esr (64-bit) and there it works without problems (with and without PIP)

Thank you very much for your support!

I have the same issue like described above.

When I execute python3 cameracontrol.py I clearly see that the video works. I also hear some sounds from the camera. But when I activate the livepreview and using from device cam (no remote preview) and turning Execute start command for preview on take picture/collage off, there is wheter a sound on my camera nor a live preview when taking a picture.

I can still replicate the problem, that the first image is not taken. That is what I tested, hopefully it helps discovering the problem:

Please use the mjpeg/go2rtc variant for preview via DSLR until the issue is solved.

SvenGuthe commented 7 months ago

I use mjpeg now. But there are also issues. Preview via Background url (CSS) does Not Work for me (CORB Issues) and the Default URL was wrong. I scripted a small workaround with an IFrame - what works perfectly. But thanks for all the hints - helped me a lot.

andi34 commented 7 months ago

As a workaround mentioned on telegram: I have the following command running as a cronjob and it works right away:

crontab -e 

@reboot python3 /var/www/html/api/cameracontrol.py -b
timo619 commented 6 months ago

With the updated version (01. May 2024) and mjpeg/go2rtc the issue (no first photo after start/reboot) is resolved, at least for me.

My setup again:

Thank you very much for help and your work. This is a really nice project.
