I have progress in my baremetal project with imx219 camera on raspberry pi 3b+.
I have vchiq and threading implemented.
I have this graph working well
"ril.camera".video_out ---> "encoder(h264)"--->compressed video written to sd card
I have and SPI display and want to draw resized video to display.
For that I have added splitter and resizer components.
My goal is to setup this:
Before trying out the full graph above, I first have implemented and tested same thing but without resizer - second splitter output was just checked for existence but ignored. It worked fine.
Now I add "ril.resize" component and start to have problems
When I create new mmal component "ril.resize" I check what is created by default:But then I immediately want to change input and output port of resizer to reflect this:
resizer.input: encoding:OPAQUE,variant:I420, width 1280x1024,framerate:0
resizer.output: encoding: RGB24, variant:0, width 320x240,framerate:0
But this fails already on the input step, here is what I see in logs:
