Session Initialization Everything starts with a session. A session represents a logical camera pipeline (e.g., "The Front Camera" or "The Cabin Camera"). qcarcam api
You must define the resolution, format (e.g., QCARCAM_PIX_FMT_RAW10 for ADAS or QCARCAM_PIX_FMT_NV12 for display), and framerate. # List all camera instances qcarcam_test -l qcarcam_test
