VideoCapture - reenable camera mode after first recording

I'm using the script for VideoCapture in the documentation here
https://developer.microsoft.com/en-us/windows/mixed-reality/locatable_camera_in_unity

The video captures and saves fine on first recording.
I'm then trying to reenable the camera to perform another capture calling the below method on tap, which is the same as the
Start method

Code (CSharp):

1. public void RestartCamera()
2.     {
3.         VideoCapture.CreateAsync(false, OnVideoCaptureCreated);
4.     }

It appears to create another VideoCapture Instance. However, when going to record again the debug log in VS
states:

Video Mode has already been started.

(Filename: C:\buildslave\unity\build\Runtime/VR/HoloLens/WebCam/VideoCapture.cpp Line: 1113)


The camera is not yet ready. (my own debug log when can't record)

(Filename: C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)

It's also the same PhotoCapture where another image can't be taken and thought the issue might be to do with

However Spatial Understanding is not enabled in my scene.

Using Unity 2017.3.0f3
So, just wondering if the right action is being called to allow more than one video to be recorded.

 

Thanks for the info. The recording starts and stops fine on first tap. Clean up is performed as per below

Code (CSharp):

1.  public void StopRecording()
2.     {
3.             Debug.Log("Stopped Recording Video");
4.             m_VideoCapture.StopRecordingAsync(OnVideoModeStopped);
5.     }
6.  
7. private void OnVideoModeStopped(VideoCapture.VideoCaptureResult result)
8.     {
9.         m_VideoCapture.Dispose();
10.         m_VideoCapture = null;
11.  
12.         Info.text = "Camera off";
13.     }
14.  

It's when calling VideoCapture.CreateAsync(false, OnVideoCaptureCreated) on tap again that the issue occurs where Video Mode still appears to be active according to VS debugging log.
Am therefore wondering if there's any clean up happening at all. I've tested with and without the Dispose() and null settings and the outcome is the same.

 

I had the video capture start and stop to work perfectly fine in a few runs of the build.
But now, It seems Video capture stop is just not stopping when I call the function. It continues to record and there is no log saying why it cant stop the capture. I didnt change anything on the scripts...

 

Hope I'm not too late.

I ran across your question and tried it myself and came up with solution:

Try
videocapture.StartVideoModeAsync()

e.g.
m_VideoCapture.StartVideoModeAsync(cam, VideoCapture.AudioState.ApplicationAndMicAudio,OnStartedVideoCaptureMode);


Note that it takes 3 parameters. I would recommend saving camera parameters as global variable in StartVideoCaptureTest() function (function provided in https://docs.unity3d.com/Manual/windowsholographic-videocapture.html ) and call camera parameter value when resuming it.

Refer to following doc.
https://docs.unity3d.com/560/Docume....WebCam.VideoCapture.StartVideoModeAsync.html

Hope this helps

 

I was experiencing an issue similar to this, except with the photo mode. Updating Unity to the latest version fixed the issue.
