I need to be able to read mov, avi, and mp4 lengths. Any ideas on components that would support this?

I'd like to find better ways than what I'm doing. You have to watch which types of files you're rendering and decide whether you want to use different playback techniques. What I've done in the past is to use the various ActiveX controls that are available, create an instance and load a file. If it loads OK, then query the Player for the duration. Then dispose of the ActiveX control that was created (like a Quicktime player, or a Windows Media Player). Sometimes, though, you don't get the information unless you actually play the file. I've once done a Quicktime file parser that looked into the file and extracted some key information, which I got based on the Quicktime format documents that are downloadable from Apple's site. It worked, but was a little gory to get working. For things that can be played by Windows Media Player, you can use something like DSPack to make a fairly lightweight and simple renderer that you can then use to get the duration of the file you loaded. But you always have to have the proper codecs on the machine in order to determine that information, because there's a certain amount of rendering done. If you're willing to venture into the wilds of DirectX/DirectShow, even using something like DSPack (www.progdigy.com) to help you, you can try the IMediaSeeking interface. But that's got limitations for certain types, like MPEG-2, I think. I'm not aware of any purely programmatic methods that you can use to extract the information about duration, etc., though I'd dearly love those. I expect that there must be some; I just don't know where to find them. And if I found them, I suspect they wouldn't be in Delphi.

Thanks, Eric Use DSPACK component, I have edited one of the dspack example to read properties of video files including duration. Its not exactly my code but merely edited code snippets here and there together. http://koti.mbnet.fi/akini/delphi/dspack/ Download file: VRMBitmap.zip See uMediaDetails.pas unit.

It returns information about Mediafiles. At this moment it supports *.avi and Vorbis (*.ogm/*.ogg), will add support for Matroska (*.mkv), *.mp4 and Quicktime. It does not need to have any codecs installed.
