I use GScrop tool to capture eg. 688x136@402fps videos with GS camera:
https://stamm-wilbrandt.de/GS
After using it for any mode different than 1456x1088, no rpicam* command preview does work (fails to start streaming).
I use "GScrop 1456 1088 60 100" to reset to full view, then rpicam* previews work again.
Today I played with picamera2 zoom demo:
https://github.com/raspberrypi/picamera ... es/zoom.py
It was surprisingly easy to get preview of centered 688x136 crop I typically use with GScrop tool:
Hopefully simple to answer questions first:
1) how to reduce height of preview to 136?
2) is pure 688x136 preview possible without a window title?
Next I tried to record 688x136 video (with default framerate for now) based on capture_video.py:
https://github.com/raspberrypi/picamera ... e_video.py
I tried many things, but always full frame got recorded![:-(]( "Sad")
How can I tell the encoder to capture 688x136 centered frame only, that I was able to preview?
