I'm encountering an error while trying to use an OV5640 camera with GStreamer. The error seems to be related to memory allocation.
What could be causing the "Failed to allocate required memory" error in the GStreamer pipeline with the OV5640 camera? How can I troubleshoot and resolve this issue?
This is my whole ERROR msg:

Thank you for any assistance you can provide!
I've been experimenting with an OV5640 camera in a GStreamer pipeline, but I keep running into the "Failed to allocate required memory" error. I've tried various elements in the pipeline and even looked into the GStreamer source files related to the error, but I'm still stuck.
Could someone offer guidance on what might be causing this issue and how I can address it?
