Qcarcam - Api Link

The Qualcomm QCarCam API is a specialized interface designed for the automotive sector, specifically as part of the Snapdragon Ride SDK and the broader Snapdragon Digital Chassis. As vehicles transition into "AI-defined" platforms, this API serves as a critical bridge between raw camera hardware and high-level safety and infotainment applications.

The QCarCam API is Qualcomm’s interface for low-level camera access on their Snapdragon Automotive platforms. Here is why it matters for automotive engineers: qcarcam api

Hardware Sync via GPIO or Frame Sync Signal

The API provides a qcarcam_set_sync_config() function that ties capture start times across sessions:
