Upload any video and convert to .mp4 online in C#

Upload any video and convert to .mp4 online in C#

In C#, you can use the FFmpeg tool to convert videos to the MP4 format. To upload a video and convert it to MP4 format online, you can create a web application that allows users to upload a video file, and then use FFmpeg to convert the uploaded file to MP4 format. Here's an example:

  • Create a web page that allows users to upload a video file. You can use the HtmlHelper class in ASP.NET MVC to create a file input element for the upload:
@using (Html.BeginForm("UploadVideo", "Home", FormMethod.Post, new { enctype = "multipart/form-data" })) { <input type="file" name="videoFile" /> <input type="submit" value="Upload" /> }
  • In the controller action that handles the file upload, use the HttpPostedFileBase class to get the uploaded file and save it to a temporary location:
[HttpPost] public ActionResult UploadVideo(HttpPostedFileBase videoFile) { // Check if a file was uploaded if (videoFile != null && videoFile.ContentLength > 0) { // Save the file to a temporary location string tempFilePath = Path.GetTempFileName(); videoFile.SaveAs(tempFilePath); // Call the ConvertVideoToMp4 method to convert the uploaded file to MP4 format ConvertVideoToMp4(tempFilePath); // Return a success message to the user ViewBag.Message = "Video uploaded and converted successfully!"; } else { // Return an error message to the user ViewBag.Message = "Please select a file to upload."; } return View(); }
  • In the ConvertVideoToMp4 method, use the FFmpeg tool to convert the uploaded video file to MP4 format:
private void ConvertVideoToMp4(string filePath) { // Get the path to the FFmpeg tool string ffmpegPath = Server.MapPath("~/App_Data/ffmpeg.exe"); // Set the output file path to a new file with .mp4 extension string outputFilePath = Path.ChangeExtension(filePath, ".mp4"); // Run the FFmpeg tool to convert the file to MP4 format ProcessStartInfo startInfo = new ProcessStartInfo { FileName = ffmpegPath, Arguments = $"-i \"{filePath}\" -c:v libx264 -c:a aac -strict experimental \"{outputFilePath}\"", UseShellExecute = false, RedirectStandardOutput = true, RedirectStandardError = true, CreateNoWindow = true }; using (Process process = new Process()) { process.StartInfo = startInfo; process.Start(); process.WaitForExit(); } // Delete the original file File.Delete(filePath); }

In this example, the ConvertVideoToMp4 method takes the path to the uploaded video file as an argument. The method uses the Process class to run the FFmpeg tool with the appropriate arguments to convert the video file to MP4 format. The output file path is set to a new file with the .mp4 extension. Once the conversion is complete, the original file is deleted.

Note that this example assumes that the FFmpeg tool is installed on the server and the path to the tool is set in the ffmpegPath variable. Additionally, it is important to validate user input and perform proper error handling to ensure the security and reliability of your application.
