Maybe I should close the issue for the moment to libcamera can already let you register an event on the completion of a raw buffer, so you could get a pretty close approximation to events when the frame completes, but it might be racy for timing on the start of the next frame. Similar command work with legacy raspivid but libcamera is required to fine tune camera parameter using the json tunning file.

The max the firmware supports is 2. Firstly, make sure you rebuild libcamera-apps after libcamera. Usually on the second attempt, the segfault does not occur. This will be happening imminently. However, it would be entirely possible to create a new libcamera-app that just memcpys the CMA buffer into another buffer or memory space and return the CMA buffer back for the hardware to reuse. The problem was fixed by adding "cam0_reg","cam0_reg_gpio=30" to the DT parameters for the default overlay in balena.
