CloseRecords a video from the web camera directly to disk.
The final video recording will be stored on the file system in the MP4 format.
The example below records a 5 second video to the file system.
using UnityEngine; using System.Collections; using System.Linq; using UnityEngine.XR.WSA.WebCam;
public class VideoCaptureExample : MonoBehaviour { static readonly float MaxRecordingTime = 5.0f;
VideoCapture m_VideoCapture = null; float m_stopRecordingTimer = float.MaxValue;
// Use this for initialization void Start() { StartVideoCaptureTest(); }
void Update() { if (m_VideoCapture == null || !m_VideoCapture.IsRecording) { return; }
if (Time.time > m_stopRecordingTimer) { m_VideoCapture.StopRecordingAsync(OnStoppedRecordingVideo); } }
void StartVideoCaptureTest() { Resolution cameraResolution = VideoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First(); Debug.Log(cameraResolution);
float cameraFramerate = VideoCapture.GetSupportedFrameRatesForResolution(cameraResolution).OrderByDescending((fps) => fps).First(); Debug.Log(cameraFramerate);

SupportedResolutions | A list of all the supported device resolutions for recording videos. |
IsRecording | Indicates whether or not the VideoCapture instance is currently recording video. |
Dispose | Dispose must be called to shutdown the PhotoCapture instance. |
GetUnsafePointerToVideoDeviceController | Provides a COM pointer to the native IVideoDeviceController. |
StartRecordingAsync | Asynchronously records a video from the web camera to the file system. |
StartVideoModeAsync | Asynchronously starts video mode. |
StopRecordingAsync | Asynchronously stops recording a video from the web camera to the file system. |
StopVideoModeAsync | Asynchronously stops video mode. |
CreateAsync | Asynchronously creates an instance of a VideoCapture object that can be used to record videos from the web camera to disk. |
GetSupportedFrameRatesForResolution | Returns the supported frame rates at which a video can be recorded given a resolution. |
OnStartedRecordingVideoCallback | Called when the web camera begins recording the video. |
OnStoppedRecordingVideoCallback | Called when the video recording has been saved to the file system. |
OnVideoCaptureResourceCreatedCallback | Called when a VideoCapture resource has been created. |
OnVideoModeStartedCallback | Called when video mode has been started. |
OnVideoModeStoppedCallback | Called when video mode has been stopped. |
