In reality, being a good programmer is about being patient, inquisitive and perceiving when things don't go right straight away. > Ok, is there any other plugin similar to ffmpeg? I give up :D Depends which platform you are working on. Under Windows there is directshow plugin and under OSX there is a quicktime, avfoundation and QTKit plugin that all try to provide some for of video (OSX's API are under just much flux as ffmpegs!) By contrast the image plugins that we really upon have long had stable API's and cause very few problems. Video by contrast is a bit of mess, with patents as well as API's making life more difficult.
