What can I build with VideoLab?

With VideoLab you can do just about anything imaginable: synthesize, capture, process, and analyze; mix, listen, visualize and more.

Applications include:

Video Capture - Record videos from camcorder, Web Cam or IP Camera.
DVD Player - Plays DVDs.
Screen Capture - Record videos from the screen.
Combine - Mix, merge, split and transition videos.
Convert - converts video from one format to another.
Filtering - perform batch filtering on videos.
Jukeboxes, and Play Lists - play sequences with cool transition effects.
Transparency - mix videos by using transparent colors.
Broadcast - compress and broadcast the video.
Playback - create playback applications.
Video editing - create video editing and analysis applications.
Video streams - watch video from video streaming servers.

Capture and record video and audio (see .NET or VCL tutorial):

The latest version of VideoLab supports the old fashioned Windows API( Video For Windows ( VFW ), VCM, WaveAPI, ACM), the newer DirectShow, DMO, the free FreeFrame and even allows if needed any mixture of them. The developer can choose the technology and can switch from one to the other at any moment: VideoLab hides the complexity of the chosen technology and makes the components look almost identical from the developer's perspective.

Here is the full list of the supported technologies:

Win32 API:

Video For Windows ( VFW )
Video Compression Manager ( VCM )
Audio Compression Manager ( ACM )
WaveAPI

DirectX:

DirectShow
Direct Media Objects ( DMO )

Intel:

Intel MMX
Intel Performance Primitives ( IPP )

Free Third Party Libraries:

FreeFrame and FreeFrameGL
VirtualDub

The library includes AVI Player, AVI Logger with compression capabilities, DirectShow Video Player and Video Logger, Noise generators, Test Image generator, Video Display, and DirectShow video Render, Histogram, a large set of filters, geometric transformation components, Mixers, Effects, a Win32 API and DirectShow Video Capture component. Some additional components from the SignalLab and PlotLab have been added to allow processing Histogram Data, and components from AudioLab are included to allow basic audio processing and display.

Our component libraries come in 3 versions a VCL - Firemonkey version (for Delphi / C++ Builder / RAD Studio 10.3 or higher), an MFC compatible Visual C++ version, and a .NET 4.0 supporting Visual Studio 2005 or higher.

The RAD Studio version is a set of native VCL and Firemonkey components of which all include now the powerful Mitov Runtime.

The Visual C++ version is a set of native Visual C++ classes (components).

The NET 4.0 (4.5 and higher compatible) version is a set of managed .NET components. The .NET version has the same performance as the native versions, and supports all the Microsoft .NET languages including Visual Basic, C#, J#, F# and C++/CLI.

Due to the unique architecture of the OpenWire platform, the components are implemented the same way in Managed .NET and native Windows (32 and 64 bit) environments. The code to control a component from VB.NET, C++/CLI, C#, and J#, Visual C++ MFC, Delphi, and C++ Builder is almost identical. This allows the developers to migrate and share code between the different environments thus significantly improving the productivity.

VideoLab: Frequently Asked Questions

Q: Does VideoLab support the format of my Video Files?

A: VideoLab supports both Win32 API and DirectShow technologies. Win32 API will allow you to play only AVI files. If you decide to use DirectShow VideoLab will use any DirectShow filter available on your system. If you have a DirectShow filter for a particular video format VideoLab will recognize the format and use the proper filter. This means that VideoLab is capable of using any format available today. If you have a file that you can’t play in VideoLab, it means that you probably don’t have the proper DirectShow filter. Please search the web and download the filter needed for the particular format.

Q: I can’t play my video file! What is wrong?

A: In order to play format other then basic AVI you must use the DirectShow TVLDSVideoPlayer component. If you still can’t play the file, please check if you have installed a DirectShow codec for the file format. VideoLab needs a codec available in the system in order to decode the file. A huge selection of codecs is available on the WEB.

Q: Do I have to purchase VideoLab?

A: VideoLab is free for non commercial purposes. This means that you can use it for personal pleasure, hobby, or evaluation purposes. If you are student you can also use it for free for your educational needs including school projects. If you are a tutor at present you also can use it for free for your classes. However in the near future a low cost tutor license will be available, and you will have to purchase it. Your students however will not need license to use the product at class.

Q: Is VideoLab multithreading? Will it stop streaming while I move the window with the mouse?

A: Yes. VideoLab is fully multithreaded and will not stop streaming while the main thread is busy.

Q: Does VideoLab support DirectShow?

A: Yes. VideoLab supports DirectShow 8.1 or higher.

Q: What version of DirectShow I need to run VideoLab?

A: VideoLab supports DirectShow 8.1 or higher.

Q: Can I capture and save bitmaps out of the video stream?

A: Yes. Check the CaptureBitmap in the demos directory.

Q: Can I create a movie from bitmaps?

A: Yes. Check the RecordBitmapsDemo in the demos directory.

Q: Can I process bitmap images with VideoLab?

A: Yes. Check the ProcessBitmap demo project in the demos directory.

Q: Can I process the video faster than the normal video speed.

A: Yes. Check the VideoConvertDemo demo in the DirectShow demoes directory.

Q: I want to copy and paste parts of the video into a new file. Can VideoLab do that?

A: Yes. VideoLab uses DirectShow to play and record files. Many formats do not allow easy positioning and can’t be used with DirectShow Editing Services. VideoLab offers a different approach. It allows you to play even non seek enabled file to a specific position and copy a portion of the file into a new one. Check the VideoConvertDemo demo in the DirectShow demoes directory.

Q: Can I play video files from a Web URL?

A: Yes. You can use the TVLDSVideoPlayer to play files as well as any video URL from the web.

Q: I want to use VideoLab. Do I have to install DirectShow?

A: DirectShow is not required on your system if you are not planning to write application using the DirectShow components of the package.
