RecordingParameters () recordingParameters. RecordingParameters recordingParameters = new sl. RuntimeParameters () // Enable recording with the filename specified in argument string output_path = args sl. RuntimeParameters runtimeParameters = new sl. SVO lets you record video and associated metadata (timestamp, IMU data and more if available). Specify an output file name (eg: output.svo) and SVO_COMPRESSION_MODE, then save each grabbed frame. To record SVO files, you need to enable the Recording module with enableRecording(). You can also add multiple GPUs in a single server to increase the number of recording sessions with hardware encoding. When using hardware encoding (H.264, H.265), make sure to check the NVENC support matrix or Jetson one which shows the maximum number of concurrent recording sessions that can be started on a single NVIDIA GPU. You can record videos with multiple cameras connected to the same PC. The updated NVENC encoder on Turing-based NVIDIA GPUs (RTX 20-Series, Jetson Xavier) will typically produce superior quality than encoders on older generation GPUs (GTX 10-Series, Jetson Nano). Encoding QualityĪt a given bitrate, hardware encoding quality can vary depending on your GPU generation. For example, in a compute-heavy scenario, it is now possible to record video at a full frame rate with minimal impact on the main application. With encoding offloaded to NVENC, the GPU and the CPU are free for other operations. They have been designed to use the hardware-based encoder (referred to as NVENC) built into NVIDIA graphics cards. NVIDIA GPU for hardware encoding, NVIDIA Jetsonįor optimal performance, we recommend using the H.264 and H.265 recording modes. These parameters can only be set before opening the camera and cannot be changed while the camera is in use.NVIDIA GPU (Pascal or above) for hardware encoding, NVIDIA Jetson ![]() zedocdepthexample.cpp, zedocrectifyexample. returns true if the camera is correctly opened. Use -1 to open the first available camera. Initial parameters let you adjust camera resolution, FPS, depth sensing parameters and more. Open a ZED camera using the specified ID or searching for the first available. To configure the camera, create a Camera object and specify your InitParameters. The API can be used with two different video inputs: the ZED live video (Live mode) or video files recorded in SVO format with the ZED API (Playback mode). To use the ZED in your application, you will need to create and open a Camera object. The ZED API provides low-level access to camera control and configuration. It is also recommended to increase the Gamma settings in low-light environments, as it can provide a considerable light boost while reducing saturated areas. If you need to reduce blur, switch to MANUAL mode and increase Gain before Exposure. When Exposure is at it’s maximum level, motion blur is increased. Tips: In AUTO mode, Exposure level will be increased first, then Gain in order to reduce noise. When camera White Balance, Exposure and Gain are in ‘Auto’ mode, they are automatically adjusted depending on the luminance in the scene. It is not possible to adjust sensor parameters individually. Note: Camera controls adjust parameters of left and right image sensors in sync. Default values are indicated in this table.įor more information on how to adjust camera settings using the API, see Camera Controls. * ANALOG_GAIN, DIGITAL_GAIN, AUTO_EXPOSURE_TIME_RANGE, AUTO_ANALOG_GAIN_RANGE and AUTO_DIGITAL_GAIN_RANGE are defined by the Jetson DTS.
