Hi to all!!!
I'm trying in a development PC Visioforge capture and all is ok. I can compile it and the video is showed in my form with the screen capture device. But when I copy that executable with all DLL's in a new formated PC with the same OS (Windows 10 x64), the screen is black and no video signal. I have installed all the automatic dependencies (https://support.visioforge.com/132619-Deployment) but no luck. In the development PC, the executable runs fine. How can I solve it? Thanks

Hi
Please implement OnError event of Video Capture class in your software to see what's wrong.

"Unable to create Output file" is the error. I dont want output video file, I only want display camera contents and get its bitmap with VideoCapture1.Frame_GetCurrent in a timer. In development PC works, in a fresh PC W10 gives me that error.
This is my code:
VideoCapture1.Video_Sample_Grabber_Enabled = True
VideoCapture1.Debug_Mode = False
VideoCapture1.Audio_RecordAudio = False
VideoCapture1.Audio_PlayAudio = False
VideoCapture1.Video_Renderer.Video_Renderer = VFVideoRenderer.EVR
VideoCapture1.IP_Camera_Source = New IPCameraSourceSettings()
VideoCapture1.IP_Camera_Source.Type = VFIPSource.Auto_LAV
VideoCapture1.IP_Camera_Source.AudioCapture = False
VideoCapture1.IP_Camera_Source.URL = "http://192.168.1.215/mjpg/1/video.mjpg"
VideoCapture1.IP_Camera_Source.Login = "root"
VideoCapture1.IP_Camera_Source.Password = "XXXXXXXXXX"
VideoCapture1.Mode = VFVideoCaptureMode.IPCapture
VideoCapture1.Start()
This is my code:
VideoCapture1.Video_Sample_Grabber_Enabled = True
VideoCapture1.Debug_Mode = False
VideoCapture1.Audio_RecordAudio = False
VideoCapture1.Audio_PlayAudio = False
VideoCapture1.Video_Renderer.Video_Renderer = VFVideoRenderer.EVR
VideoCapture1.IP_Camera_Source = New IPCameraSourceSettings()
VideoCapture1.IP_Camera_Source.Type = VFIPSource.Auto_LAV
VideoCapture1.IP_Camera_Source.AudioCapture = False
VideoCapture1.IP_Camera_Source.URL = "http://192.168.1.215/mjpg/1/video.mjpg"
VideoCapture1.IP_Camera_Source.Login = "root"
VideoCapture1.IP_Camera_Source.Password = "XXXXXXXXXX"
VideoCapture1.Mode = VFVideoCaptureMode.IPCapture
VideoCapture1.Start()

Ok, solved (putting a outputfile name in the control) but I got a strange behaviour.
If a set capturemode to IPpreview the video has 2-3 seconds of delay.
If a set capturemode to IPCapture with outputfile to any name but without output format (like me above code) then it does'nt create a output video file but video is in REALTIME in the screen.. ?????????? What am I doing wrong????
