Although not specifically tested, our components should run OK under Delphi 4, 5 and 6. We have received some reports from users about certain incompatibilities of earlier versions of @ctiVideo with Delphi 4. If you are experiencing probles with our controls, please send us an email at support@activevideotools.com or use our on-line bug report form here.

We are constantly expanding our samples library. All the samples are available here. If you have successfully implemented any of our products with another development platform and would like to share your experience and code with our developers community, please send an email to code@activevideotools.com.

The current versions of @ctiVideo and AVIEncoder only support PCM audio formats. There are plans for future versions to support audio compression CODECs.

You can set the .CaptureAudio property of the source @ctiVideo OCX to FALSE to prevent audio from being captured.

The CODECs are installable pieces of software, which encode and decode the audio and video signal. Some of them come with Windows (like MS Video 1, Intel Indeo 3.4, Cinepak), others are installed by some software packages (Like Microsoft Windows Media MPEG4, etc.), while third are hardware related products, which are available only on computers that have certain video hardware (like Winnov WNV1, ATI Video, etc.). You have to make sure that you are using for recording a CODEC, which is available on the machine you'll be using for playback.

You can find more information about video CODECs here:

Most probably they are missing a video CODEC. See "What is a Video CODEC?" question for more details.

WMFEncoder component is based on the Windows Media Format SDK (same technology as Microsoft Windows Media Encoder). Thus it has all the inherent features and limitations of the streaming platform it uses - including the buffering and the delay. If you need a real-time stream, you might want to enter the Beta program for our @ctiVideo.Conf components, which are based on the Microsoft NetMeeting SDK.

You can use Windows Media Player (www.windowsmedia.com) or any other player, which supports AVI format. To open a file, just point the player to the fully qualified filename.

Yes, you can use the DivX codec with our products. You can either use the compression dialog of the control and select the codec from the list of available codecs, or use @ctiVideo together with AVIEncoder to gain programmatically access to the codec selection and properties.
