I’d written a previous post about editing files with Encoder v2 in the SDK however in V3 we changed things a little bit to support adding multiple files to a single timeline. In the case where you want to edit bits out of a single file you now need to go through the Source object.
Here’s some sample code that does this which should hopefully be self-explanatory.
// Create a media item and get a pointer to the inital source. MediaItem item = new MediaItem(@"c:\users\Public\Videos\Sample Videos\Wildlife.wmv"); Source source = item.Sources; // Change the first clip so that instead of spanning the entire file // I'm just going to encode the bit from 5 to 10 seconds. source.Clips.StartTime = new TimeSpan(0, 0, 5); source.Clips.EndTime = new TimeSpan(0, 0, 10); // Also add the bit from 20 to 30 seconds from the original file. TimeSpan secondClipStart = new TimeSpan(0,0,20); TimeSpan secondClipEnd = new TimeSpan(0,0,30); source.Clips.Add(new Clip(secondClipStart, secondClipEnd));
