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.
