FFMpegSharp is a great way to use FFMpeg encoding when writing video applications, client-side and server-side. It has wrapper methods that allow conversion to all web formats: MP4, OGV, TS and methods of capturing screens from the videos.
Setup your app config (ffmpeg files can be found in the 'Resources' folder):
<appSettings>
<add key="ffmpegRoot" value="C:\ffmpeg\bin\" />
</appSettings>FFProbe is used to gather video information
static void Main(string[] args)
{
string inputFile = "G:\\input.mp4";
// loaded from configuration
var video = new VideoInfo(inputFile);
string output = video.ToString();
Console.WriteLine(output);
}Sample output:
Video Path : G:\input.mp4
Video Root : G:\\
Video Name: input.mp4
Video Extension : .mp4
Video Duration : 00:00:09
Audio Format : none
Video Format : h264
Aspect Ratio : 16:9
Framerate : 30fps
Resolution : 1280x720
Size : 2.88 MbConvert your video files to web ready formats:
static void Main(string[] args)
{
string inputFile = "input_path_goes_here";
FileInfo outputFile = new FileInfo("output_path_goes_here");
var video = VideoInfo.FromPath(inputFile);
// easily track conversion progress
video.OnConversionProgress += video_OnConversionProgress;
// input and output strings are required
// all other parameters are optional
video.ConvertTo(VideoType.Mp4, outputFile, Speed.UltraFast,
VideoSize.Original,
AudioQuality.Hd,
true,
false);
video.ConvertTo(VideoType.Ogv, outputFile, Speed.UltraFast,
VideoSize.Original,
AudioQuality.Hd,
true,
false);
video.ConvertTo(VideoType.Ts, outputFile, Speed.UltraFast,
VideoSize.Original,
AudioQuality.Hd,
true,
false);
}
static void video_OnConversionProgress(double percentage)
{
Console.WriteLine("Progress {0}%", percentage);
}Easily capture screens from your videos:
static void Main(string[] args)
{
string inputFile = "input_path_goes_here";
FileInfo output = new FileInfo("output_path_goes_here");
var video = VideoInfo.FromPath(inputFile);
video.Snapshot(output, new Size(200, 400), TimeSpan.FromMinutes(1));
}Join video parts:
static void Main(string[] args)
{
FFMpeg encoder = new FFMpeg();
encoder.Join(new FileInfo(@"..\joined_video.mp4"),
VideoInfo.FromPath(@"..\part1.mp4"),
VideoInfo.FromPath(@"..\part2.mp4"),
VideoInfo.FromPath(@"..\part3.mp4"));
}Strip audio track from videos:
static void Main(string[] args)
{
string inputFile = "input_path_goes_here",
outputFile = "output_path_goes_here";
VideoInfo.FromPath(inputFile).Mute(new FileInfo(outputFile));
}Save audio track from video:
static void Main(string[] args)
{
string inputVideoFile = "input_path_goes_here",
outputAudioFile = "output_path_goes_here";
VideoInfo.FromPath(inputVideoFile).ExtractAudio(new FileInfo(outputAudioFile));
}Add audio track to video:
static void Main(string[] args)
{
string inputVideoFile = "input_path_goes_here",
inputAudioFile = "input_path_goes_here",
outputVideoFile = "output_path_goes_here";
FFMpeg encoder = new FFMpeg();
VideoInfo.FromPath(inputVideoFile).ReplaceAudio(new FileInfo(inputAudioFile), new FileInfo(outputVideoFile));
}Add poster image to audio file (good for youtube videos):
static void Main(string[] args)
{
string inputImageFile = "input_path_goes_here",
inputAudioFile = "input_path_goes_here",
outputVideoFile = "output_path_goes_here";
FFMpeg encoder = new FFMpeg();
var image = (Bitmap)Image.FromFile(inputImageFile);
image.AddAudio(new FileInfo(inputAudioFile), new FileInfo(outputVideoFile);
}Control over the 'FFmpeg' process doing the job:
static void Main(string[] args)
{
string inputVideoFile = "input_path_goes_here",
outputVideoFile = "input_path_goes_here";
FFMpeg encoder = new FFMpeg();
// start the conversion process
Task.Run(() => {
encoder.ToMp4(new VideoInfo(inputVideoFile), new FileInfo(outputVideoFile));
});
// stop encoding after 2 seconds (only for example purposes)
Thread.Sleep(2000);
encoder.Stop();
