Question Failed to record tagged camera via recorder

Hi,

I am tring to manage the recording from the selected camera.

The goal: I have a few cameras in the scene and I need to capture video from all of them.

What I tried: I wrote the script which is rendering mp4 file for all cameras based on their tags but all of them have a black screen after the recording is finished. Then I used a recorder (version: 3.0.3), select TaggedCamera as a source and record the animation (to verify if it works at all for tagged camera)




The problem: Every time the mp4 has a black screen. Only if I select display, in game mode, which contains the view from this camera, then the mp4 file is correct, so it seems like the recorder always takes the game view. Is it a common bug?

 

And here is my script which suppose to record from all selected cameras.

Code (CSharp):

1. public class MovieRecorder : MonoBehaviour
2. {
3.     RecorderController m_RecorderController;
4.     public bool m_RecordAudio = true;
5.     //internal MovieRecorderSettings m_Settings = null;
6.     protected List<GameObject> cameras = new List<GameObject>();
7.  
8.  
9.     void OnEnable()
10.     {
11.         Initialize();
12.     }
13.  
14.     internal void Initialize()
15.     {
16.         var controllerSettings = ScriptableObject.CreateInstance<RecorderControllerSettings>();
17.         m_RecorderController = new RecorderController(controllerSettings);
18.  
19.         var mediaOutputFolder = new DirectoryInfo(Path.Combine(Application.dataPath, "..", "SampleRecordings"));
20.         foreach (Transform child in transform)
21.         {
22.             cameras.Add(child.gameObject);
23.         }
24.         foreach (var camera in cameras)
25.         {
26.            // Video
27.             var videoRecorder = ScriptableObject.CreateInstance<MovieRecorderSettings>();
28.             videoRecorder.name = camera.name;
29.             videoRecorder.Enabled = true;
30.  
31.             videoRecorder.CaptureAlpha = true;
32.  
33.             // This example performs an MP4 recording
34.             videoRecorder.OutputFormat = MovieRecorderSettings.VideoRecorderOutputFormat.MP4;
35.             videoRecorder.VideoBitRateMode = VideoBitrateMode.High;
36.  
37.             print(camera.tag);
38.             videoRecorder.ImageInputSettings = new CameraInputSettings
39.             {
40.                 Source = ImageSource.TaggedCamera,
41.                 OutputWidth = 1920,
42.                 OutputHeight = 1080,
43.                 CameraTag = camera.tag
44.                 //RecordTransparency = false,
45.                 //CaptureUI = false,
46.                 //FlipFinalOutput = false
47.             };
48.  
49.             videoRecorder.AudioInputSettings.PreserveAudio = m_RecordAudio;
50.  
51.             // Simple file name (no wildcards) so that FileInfo constructor works in OutputFile getter.
52.             videoRecorder.OutputFile = mediaOutputFolder.FullName + "/" + "video_" + camera.name;
53.  
54.  
55.             // Setup Recording
56.             controllerSettings.AddRecorderSettings(videoRecorder);
57.  
58.             //Debug.Log($"Started recording for file {OutputFile.FullName}");
59.         }
60.  
61.         controllerSettings.SetRecordModeToManual();
62.         controllerSettings.FrameRate = 60.0f;
63.  
64.         RecorderOptions.VerboseMode = false;
65.         m_RecorderController.PrepareRecording();
66.         m_RecorderController.StartRecording();
67.     }
68.  
69.     void OnDisable()
70.     {
71.         m_RecorderController.StopRecording();
72.     }
73. }
