Canon EOS 700D: Liveview not starting

[foxinsox]

Hey,
i wanted to check out this amazing project with my canon eos 700D (switched on in camera mode), so I downloaded and deployed your latest Image from the image repository, but unfortunately it didn't succeed.
It seems like the Raspberry Pi 3, Model B doesn't really start the application.. Please refer to the added Screenshots for the full console log.
It sets up the WiFi and I can connect to it and ping it under 172.24.1.1, but none of the API calls works yet. Also it recognizes the camera model if i plug it off and in again.

Also when I'm listing all the processes, i can neither find it there after restart nor after running either ./camera-toolbox or QT_QPA_EGLFS_FORCE888=1 ./camera-toolbox

[rlamarche]

This very strange that you don't get any message. You run from ssh isn't it ? Can you try to run directly from the RPI ?

[foxinsox]

I tried it both ways but unfortunately it makes no difference.

[rlamarche]

After a test, run dmesg and paste it here please

[foxinsox]

I restarted without camera now, but plugged it in again at sec 26 as you can see…

[protobubble]

Same camera here, same issue. I've run into strange things like this before in my previous gphoto2 projects. Question: In your readme you mentioned that you are packaging libgphoto2 into this project's build. What version are you packaging, or are you referencing the latest versions by default? Certain earlier versions of libgphoto2 have an issue requiring a usbreset to be sent to the pi in order for the camera to recognize again.

Also: How are you implementing the camera-toolbox start on boot?

I have a 700D and will be testing this early this week.

[rlamarche]

Indeed I was packaging libgphoto2, but now I've removed it from the project (but I still reference it with git submodule).
This was to allow debugging libgphoto and patching it easily.

Can you update the cameratoolbox binary and try again please ? You need the latest version so that it recognize canon camera.
Unzip this file in /usr/local/bin :
camera-toolbox.zip

@foxinsox this the same binary that you should have already installed previously here rlamarche/camera-toolbox-images#1 (comment)

@protobubble on boot, I try to detect the camera model and start toolbox : https://github.com/rlamarche/camera-toolbox/blob/master/app/main.cpp#L177

On the init sequence I get some infos :
https://github.com/rlamarche/camera-toolbox/blob/master/app/gphoto/gpcamera.cpp#L146

[rlamarche]

The version of libgphoto2 in the image is 2.5.11.
The latest version is 2.5.12.

http://gphoto.org/news/

@protobubble do you want to try with a specific version of libgphoto ? let me know

[foxinsox]

Hej @rlamarche , thanks for coming back on this.
Meanwhile, i made a build of this project with libgphoto2 v 2.5.12 via CT Creator on my linux machine. Maybe it helps solving those Canon issues?

What happens at first is that the program "canon digital camera" opens automatically and claims the camera. Camera-toolbox fails due to this:

1 cameras detected.
Open camera : "Canon EOS 700D" at port "usb:001,009"
Error : "Unable to get root widget : Could not claim the USB device"

I remember calling killall PTPCamera under OSX helped on this, but under linux it doesn't work and i haven't found the according PID yet. So i have to unmount it manually.
I wonder: How is this solved on the raspberry pi? Is there maybe any other programm claiming the canon camera before camera-toolbox does?

When i run the program again after i manually unmounted the camera from the "canon digital camera" software, camera-toolbox starts successfully. I can see a black window with some camera settings and I can run most commands like setting Aperture, ISO or Speed or trigger a picture capture. However, the live-view does not work:

The EOS 700 D is on movie record mode and i can see the live-view on the cameras display.

[foxinsox]

Actually i just see that the programm creates a GPCanonCamera instance, but unlike the GPNikonCamera class you haven't implemented any methods for live-view yet. So i guess by now it's not even supposed to work at all?
https://github.com/rlamarche/camera-toolbox/blob/master/app/gphoto/canon/gpcanoncamera.cpp#L82

[rlamarche]

Hi,

Just a quick reply : the "startliveview" is not really needed neither on Nikon nor Canon camera because libgphoto should start it automatically when requesting for preview.

Thank you for your feedback above, I'll look at it when I'll have the time 👍

[foxinsox]

WOW, Amazing!!! Quick update:
Apparently i was too stupid to find the right key combination for hitting "enter" on my macbook-virtual machine ubuntu setup… Now I just started the liveview via
curl --request POST http://[Pi IP]:8080/api/v1/liveview/start
and it works! :) Framerate is just around 8fps, but maybe that's due to my system running on a virtual machine with two cores only… Is it going any faster on the raspberry pi?

[rlamarche]

Hi,
Good news 👍

With a nikon camera and raspberry pi 3, I get between 25 and 40 fps. Maybe more I don't remember - it depends of the camera mode. For example, if I set the mode 1280x720 60fps, I should get 60fps.

I don't think that your virtual machine is limiting you here.
I think that canon camera need tuning to increase the framerate like decreasing the liveview resolution.
On my Nikon the resolution is 640x426. On Canon it is more I think.

Can you get a single preview image on this url : http://..../api/v1/preview.jpg and publish it here please ?
Thank you.
