Description
In the sample, the user can select an image filter in the composition picker to generate videos with special effects. The supplied composition grabs the input video and output a sequence of images. The images are then processed with an image filter selected by the user to produce video with special effects. A QCCompositionPickerPanel is used to provide the image filters for the user to select. When a filter is selected, the application will receive a notification and it will pass the selected filter identifier as the new input parameter for the composition in the QCView. This filter is then applied to process the images.
