Version 1.0.0.0 of splicer (the little video/audio composition library that leverages DirectShow which I started a few years ago) is now available on Codeplex
here this marks a milestone in stability, and probably the main "feature" of this release is 64bit support, something that's been bugging me for ages as I could only work on the project in a VM!

A quick list of changes since the last release are:

• Now uses DirectShow.Net 2.0 (thanks to felix, a fellow NZ'r).
• RenderProgress event.
• Renderers are disposable.
• Support for 64bit operating systems.
• Vista fixes/support.
• Additional samples (i.e. SampleTimeWatermarkParticipant, and a few others).
• Tests updated for NUnit 2.4.7.
• Solution upgraded to VS2008.

What's splicer?

With this library and a little imagination you can:

• Encode video or audio suitable for use on a website.
• Create slide shows from images, videos and audio.
• Apply effects and transitions to audio and video.
• Grab System.Drawing.Image clips from a video at certain times.
• Modify individual video frames during encoding via standard C# mage Drawing code.
• Add new soundtracks to existing video clips.
• Watermark videos.
• Build a video editing suite, if you were so inclined.
