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

Closed r07aNd closed 2 months ago

r07aNd commented 9 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

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 8 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 8 months ago

Yes permissions for camera usage has been granted within Firefox

Could you please disable PIP and try again?

r07aNd commented 8 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 5 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 5 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 5 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.
