> "gles context that is bigger than the display size" - what does this mean?
I meant a pi plugged into a 1280x800 hdmi monitor; when booting, the GPU
initializes to 1280x800 (because of the edid); the pipeline Philippe described
automatically negociates to the source default resolution, which is 1920x1080,
and glimagesink apparently fails to create the context in these conditions.
@philippe, what is the resolution of the monitor in your case ?
I'm still to find a way to simulate this, and i'm not entirely certain it is
the problem because setting the pi hdmi_mode to low resolution (640x480) does
not reproduce the issue.
It could also be a GPU memory limitation (since omx and rpicamsrc are both
using the gpu).
I'll try to find more about the issue conditions
