Early access to Qcarcam 2.0 requires signing an NDA with Qualcomm's automotive division.
It handles real-time camera events, such as frame triggers or error detection, and sends them to the appropriate processing threads. qcarcam api
The QCarCam API does not operate in isolation but is integrated into a broader automotive software ecosystem: GStreamer and V4L2 : Developers can use the Qualcomm Camera Driver
Every call to qcarcam_initialize() must be matched with a qcarcam_uninitialize() . This ensures that sockets are closed, buffers are freed, and the camera subsystem can be reinitialized cleanly. qcarcam_stream_config_t stream_cfg; stream_cfg
qcarcam_init_params_t init_param = .debug_mask = QCARCAM_DBG_INFO, .num_sessions = 1 ; qcarcam_init(&init_param);
// Conceptual Example: Configuring buffer allocation qcarcam_buffer_config_t buf_config; buf_config.min_buffers = 4; // Triple buffering to prevent drops buf_config.mem_type = QCARCAM_MEM_ION; // No CPU mapping buf_config.ion_heap_id = ION_SYSTEM_HEAP_ID; // Or ION_CP_MM_HEAP_ID for secure content qcarcam_set_buffer_config(session, &buf_config); This ensures that sockets are closed, buffers are
You can configure two streams from one camera session:
