The output format ( bmp, gif, jpg, png or tif) The following options are available: Option The section in which the options must be in is "SheetOptions". exe) by using the Settings dialog of the application or with a text editor. You can edit or create the standard configuration file (same filename as the application but with. The configuration file is a standard MS INI file. There are two ways to set those options: Using commandline parameters or an configuration file. Use exact time positions or key-frames only.The image format Bitmap, GIF, JPEG, PNG or TIFF (and quality if JPEG is selected).Choose the filename of the image automatically (same as the movie file but image extention).Close the applicatoin automatically when a passed job via commandline is finished.There are also some options to configure how the application should akt: The border color of the frames and if it is to be drawn.The index (time position) font style, text and shadow color.The padding between the frames (two times between header and frames) in pixel.The margin around the whole sheet in pixel.The number of columns and rows of video frames.There options to define how the sheet is designed. The application can be used to create thumbnail sheets from multimedia files. To find out about the classes and functions needed to find information about a multimedia file, seek in a video stream and extract frame images I used the FFmpeg Documentation: Using the application I had to make a few changes mainly to support the meta data extration otherwise I would have imported the project directly. The core of this project is based on the FFmpeg.AutoGen wrapper by Ruslan-B on GitHub ( ). NET library to map ffpmeg DLLs and use them to extract frame images from a multimedia file and an application to easily create thumbnail sheets using the library. NET and after many disappointing projects which I coulnd't get to work I found FFmpeg.AutoGen which worked from the start with the example. So I started some research for possibilities to pinvoke FFmpeg DLLs directly in. But that method didn't satisfy me because it's everything but a clean way. I've already published the article " Another FFmpeg.exe C# Wrapper" using FFmpeg.exe via commandline parameters to extract frame images. Download FFmpegWorker (Source only).zip Introduction
