TVideoGrabber .NET Video SDK 12.1.1.2

TVideoGrabber is a video capture / media player SDK for development of C#, VB, C++, Delphi, C++Builder, Lazarus and ActiveX-compatible applications.

Powerful and intuitive to use, TVideoGrabber will help you to save time, money and effort to include video and/or audio capabilities in your project.

TVideoGrabber captures and records video and audio streams from video capture devices supplied with a DirectShow driver like USB webcams, USB analog capture devices, HD PCI cards, desktop, as well as from set of bitmaps used as video source.

By installing our optional RTSP/RTMP DirectShow source filter it is possible to preview and record IP cameras, RTSP, RTMP, HTTP, Shoucast and various other streaming sources.

The RTSP filter is able to preview, render and save at the same time the streaming source to a file without transcoding, and generate new files on the fly without loosing frames.

When the RTSP/RTMP DirectShow source filter is installed TVideoGrabber supports also capture devices with a hardware encoder like the Avermedia Live Gamer portable, BlackMagic Decklink, Hauppauge Colossus, etc...

Most of the encoding formats are supported, natively or by using third-party codecs.

You can stream audio/video to the network, directly or through a Windows Media server.

TVideoGrabber is also an advanced media player that lets play audio/video clips at their normal speed, faster, slower, forward and backward, one by one or through a playlist.

It is possible to capture frames, perform text/graphic overlays over the video frames or only over the video window, during preview, recording or playback, perform PIP video from another TVideoGrabber component, apply video processing like rotation, cropping and more.

TVideoGrabber can merge several clips into a single one, split a clip into smaller clips and re-encode them to different formats.

TVideoGrabber is designed to be easy and comprehensive to use.

Several instances of TVideoGrabber can run concurrently, e.g. to display a video capture window and a media player window on the same form, or to run several cameras concurrently on the same form.

The package includes demo projects showing how to implement the simplest as well as the most advanced features, with only a few lines of code.

Features

VIDEO PREVIEW

The TVideoGrabber SDK supports most of the video capture devices supplied with a DirectShow driver:

• standard and HD webcams (e.g. the Logitech webcams)
• professional HD capture/rendering cards (e.g. the BlackMagic Decklink capture cards)
• capture cards including a H264 or MPEG hardware encoder, e.g. like the AverMedia Live Gamer Portable, the Hauppauge Colossus (require our Datastead RTSP filter),
• analog composite USB capture (e.g. the Easycap USB)
• PCI/PCIe analog composite capture cards (e.g. the OsPrey 210 or OsPrey 440)
• IP cameras in H264/MPEG4 mode (require our Datastead RTSP filter),
• IP cameras in HTTP/MPEG or JPEG mode,
• GigE cameras (e.g. PointGrey cameras)
• DV capture devices.

VIDEO RECORDING

• AVI recording,
• WMV/ASF recording,
• MKV recording after installing the Haali MKV muxer,
• MP4/FLV recording (may require a third-party H264 or AAC DirectShow encoder),
• timer-based recording (delayed start, timered stop, or create new file periodically)
• compression of the audio and video streams, "on-the-fly" or after recording,
• pause/resume during recording, with possibility to create a new clip for each pause/resume,
• video preview while recording,

AUDIO RECORDING

• to WAV, MP3 or WMV

MEDIA PLAYER

• play most of the audio/video formats: WMV, AVI, ASF, MPG, FLV, MP4, MOV, MP3, WAV (some formats may require compatible decoders)

• playlist support,
• playback at higher or lower speed, forward or backward,
• fast seeking, forward or backward,
• synchronization of several TVideoGrabber player components,
• play streaming sources
• opens static JPEG, BMP, PNG, GIF image files, allowing image processings and overlays

FRAME CAPTURE

• to HBitmap, TBitmap, BMP and JPEG files
• during preview, recording or playback,

LIVE NETWORK STREAMING

• supports username/password authentication on IP cameras with secured login
• PTZ control

MOTION DETECTION

• the video frame area can be divided in motion dection cells,

MULTIPLE VIDEO WINDOWS

• up to 10 display windows can be assigned to different monitors (e.g. a small video window on a monitor and a full screen video on the 2nd and 3rd monitors)

VIDEO PROCESSING AND OVERLAYS

• multiple text and image overlays, over the video frame or directly over the video window(s),
• rotation, resizing, alpha blending, chroma keying,

• recording of the extended desktop across several monitors,
• recording of a given window identified by its name or handle

CROPPING AND ZOOMING

• recording of only a cropped area of the video source
• zooming within areas the video source

VIDEO CLIP BUILT FROM BITMAPS OR IMAGE FILES (BMP, JPEG, GIF, PNG, etc...)

• the final frame rate can be adjusted at the end of the recording

REENCODING OF VIDEO AND AUDIO CLIPS

• by using the installed audio and/or video compressors,
