Qcarcam Api Site
QCarCam API is a specialized interface within the Qualcomm Camera Driver
- Hardware-accelerated: Directly leverages Qualcomm’s Image Signal Processor (ISP) and Hardware Video Encoder/Decoder.
- Latency-optimized: Designed for real-time constraints typical in automotive (e.g., <50ms end-to-end latency for surround view).
- Multi-camera synchronous: Offers native support for stitching, warp, and synchronization across up to 8 or more cameras.
Outputs were JSON-first, but QCarCam also offered SDKs to render interactive replays: synchronized map tracks, scrubbers to jump to sensor-triggered frames, and toggles to show/hide redaction layers. qcarcam api
