Basically, this is what our program is going to do but this time around without the command prompt. What that argument above does is that it creates a converted video version of the file input.avi to output.flv in our C: directory. Note that different arguments can be parsed to ffmpeg for various kinds on conversion, but for the purpose of this tutorial, we will stick to the very basic commands needed to convert our video file. flv file, we just need to enter the command: avi video file in our C: directory and want to convert that video to a. Now let's say ffmpeg is located in C:\ i.e., C:\ffmpeg.exe, we navigate to our C: directory on the command prompt and type in a few commands into ffmpeg. Open the command prompt in your Windows environment and navigate to the directory where ffmpeg.exe is located. You need to have the binary version, i.e., ffmpeg.exe in the application directory of your project. (MSDN 2008)įfmpeg is freely available on the internet. When the method is finished, the BackgroundWorker alerts the calling thread by firing the RunWorkerCompleted event, which optionally contains the results of the operation. Your calling thread continues to run normally while the worker method runs asynchronously. To use a BackgroundWorker, you simply tell it what time-consuming worker method to execute in the background, and then you call the RunWorkerAsync method. The BackgroundWorker component gives you the ability to execute time-consuming operations asynchronously ("in the background"), on a thread different from your application's main UI thread. I had that problem whenever I started the ffmpeg process. BackgroundWorker prevents our form from hanging while the conversion is in progress. The application uses a background worker. We will execute ffmpeg from our application and send these parameters to ffmpeg without displaying the command line window.ĭownload the source code here to see how it works. ffmpeg uses command line arguments for its conversion and this is what we are going to do with our. NET while playing with ffmpeg.įfmpeg is an open source command line audio / video converter.
This is a simple video converter developed with.
