Camera Sensor Drivers Compliance

on YouTube ↗36m

" summary

V4L2 has a compliance tool but it misses functional expectations, so libcamera becomes the common consumer and adds concrete fixes: libcamera helpers translate generic analog-gain and exposure values into sensor register values, exposure is normalized to lines, and blanking/exposure ordering is codified. Practical testing shows surprising gaps — only six drivers advertise the control flag that signals buffer layout changes — and device-tree rotation blobs often embed flips. The helper work unifies many drivers but gaps remain and expanded compliance tests are needed.
