Preview and recording of IP cameras and URL sources

Description

Note: with IP cameras supporting the ONVIF protocol no need to know RTSP URL syntax anymore, you can open the RTSP URL by specifying the onvif:// protocol following by the IP address or domain name and port

Preview only:

VideoGrabber.VideoSource = vs_IPCamera

VideoGrabber.OpenURLAsync = true; // default, so the connection does not block the main thread

VideoGrabber.IPCameraURL = "onvif://192.168.0.25:80" // if the port is not specified the default port 80 is used

VideoGrabber.SetAuthentication (at_IPCamera, "root", "admin")

VideoGrabber.AudioDeviceRendering = true // optional, if audio rendering is needed

VideoGrabber.FrameGrabber = fg_Disabled // if no overlay or frame capture is required, saves CPU

VideoGrabber.StartPreview()

Preview and recording:

VideoGrabber.VideoSource = vs_IPCamera

VideoGrabber.OpenURLAsync = true; // default, so the connection does not block the main thread

VideoGrabber.IPCameraURL = "onvif://192.168.0.25:80" // if the port is not specified the default port 80 is used

VideoGrabber.SetAuthentication (at_IPCamera, "root", "admin")

VideoGrabber.FrameGrabber = fg_Disabled // if no overlay or frame capture is required, saves CPU

VideoGrabber.RecordingInNativeFormat = true

VideoGrabber.RecordingMethod = rm_MP4

VideoGrabber.AudioRecording = true // optional, if the URL has audio and audio recording is needed

VideoGrabber.StartRecording()

Recording only (no decoding, saves CPU):

VideoGrabber.VideoSource = vs_IPCamera

VideoGrabber.OpenURLAsync = true; // default, so the connection does not block the main thread

VideoGrabber.IPCameraURL = "onvif://192.168.0.25:80" // if the port is not specified the default port 80 is used

VideoGrabber.SetAuthentication (at_IPCamera, "root", "admin")

VideoGrabber.RecordingInNativeFormat = true

VideoGrabber.RecordingMethod = rm_MP4

VideoGrabber.FrameGrabber = fg_Disabled

VideoGrabber.VideoRenderer = vr_None

VideoGrabber.StartRecording()

To close the current file and start recording to a new file while the recording is running, invoke RecordToNewFileNow, this will generate a new file on the fly without loosing frames.

Alternatively it is possible to enable the RecordingTimer to periodically close the current file and generate a new file.

In this case the file name is generated automatically, however the file names can be renamed on the fly from the OnRecordingCompleted event.

RTSP, RTMP, HTTP, UDP, MMS, RTP sources and other streaming protocols

The sample code is the same, e.g.:

IPCameraURL = "rtsp://192.168.5.25/axis-media/media.amp?videocodec=h264&audio=1"

IPCameraURL = "udp://192.168.0.25"

IPCameraURL = "mmsh://192.168.0.25"

IPCameraURL = "rtmp://192.168.0.25/live"

IPCameraURL = "rtp://192.168.0.25"

IPCameraURL = "http://192.168.0.25/url"

etc...
