No Capture on Canon EOS 1200D

[ghost]

I created gPhoto live preview capture and it gets the Camera and stuff but it doesn't show a video capture.
In my terminal there is the following:
error: glMapBuffer failed, glGetError returned 0x505
error: gs_texture_map (GL) failed

Versions:
aur/obs-gphoto 0.3.0-1
community/obs-studio 21.0.2-1

At now, it's a strange question, but you are using a 32 or 64 bit OS?
Can you show "pacman -Qs gstreamer" comand output?

I'm found somefing like this "glGetError 0x505 == out of memory reported by the opengl gpu driver".
Can it be that you are using an old or integrated video card with a small RAM size?

I have no ideas, because I use the same distrib and camera as you. last try ldd /usr/lib/obs-plugins/obs-gphoto.so output?

[Atterratio]

Try to update the system and rebuild the plugin, if you have't do so already.
Are there any other programs that can be occupied by the camera, such as a photo manager or automatic camera storage?
Does the camera do any actions, before it starts to show preview it should raise the mirror?
Any errors at "gphoto2 --capture-preview", obs should not been run?

I had a similar issue with a Canon 80D in Lubuntu. Camera recognized by the plug-in but no picture. It turns out that Lubuntu was automatically mounting the camera as a USB device when it was plugged in. "Ejecting" or unmounting the camera before starting OBS fixed the issue.

Just as a side note, the file manager strangely showed two cameras connected. I was only able to unmount one of them. But that seemed to solve the issue. I think that may be some weirdness with my desktop manager and has nothing to do with this plugin or obs.
