Install-Package FFMpegSharp
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";
var encoder = new FFMpeg();
FileInfo outputFile = new FileInfo("output_path_goes_here");
var video = VideoInfo.FromPath(inputFile);
// easily track conversion progress
encoder.OnProgress += (percentage) => Console.WriteLine("Progress {0}%", percentage);
// MP4 conversion
encoder.Convert(
video,
outputFile,
VideoType.Mp4,
Speed.UltraFast,
VideoSize.Original,
AudioQuality.Hd,
true
);
// OGV conversion
encoder.Convert(
video,
outputFile,
VideoType.Ogv,
Speed.UltraFast,
VideoSize.Original,
AudioQuality.Hd,
true
);
// TS conversion
encoder.Convert(
video,
outputFile,
VideoType.Ts
);
}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);
new FFMpeg()
.Snapshot(
video,
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")
);
}Join image sequences:
static void Main(string[] args)
{
FFMpeg encoder = new FFMpeg();
encoder.JoinImageSequence(
new FileInfo(@"..\joined_video.mp4"),
1, // FPS
ImageInfo.FromPath(@"..\1.png"),
ImageInfo.FromPath(@"..\2.png"),
ImageInfo.FromPath(@"..\3.png")
);
}Strip audio track from videos:
static void Main(string[] args)
{
string inputFile = "input_path_goes_here",
outputFile = "output_path_goes_here";
new FFMpeg()
.Mute(
VideoInfo.FromPath(inputFile),
new FileInfo(outputFile)
);
}Save audio track from video:
static void Main(string[] args)
{
string inputVideoFile = "input_path_goes_here",
outputAudioFile = "output_path_goes_here";
new FFMpeg()
.ExtractAudio(
VideoInfo.FromPath(inputVideoFile),
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();
new FFMpeg()
.ReplaceAudio(
VideoInfo.FromPath(inputVideoFile),
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();
((Bitmap)Image.FromFile(inputImageFile))
.AddAudio(
new FileInfo(inputAudioFile),
new FileInfo(outputVideoFile)
);
/* OR */
new FFMpeg()
.PosterWithAudio(
inputImageFile,
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.Convert(new VideoInfo(inputVideoFile), new FileInfo(outputVideoFile));
});
// stop encoding after 2 seconds (only for example purposes)
Thread.Sleep(2000);
encoder.Stop();
}Video Size enumeration:
public enum VideoSize
{
HD,
FullHD,
ED,
LD,
Original
}Speed enumeration:
public enum Speed
{
VerySlow,
Slower,
Slow,
Medium,
Fast,
Faster,
VeryFast,
SuperFast,
UltraFast
}Audio codecs enumeration:
public enum AudioCodec
{
Aac,
LibVorbis
}Audio quality presets enumeration:
public enum AudioQuality
{
Ultra = 384,
Hd = 192,
Normal = 128,
Low = 64
}Video codecs enumeration:
public enum VideoCodec
{
LibX264,
LibVpx,
LibTheora,
Png,
MpegTs
}Custom video converting presets could be created with help of ArgumentsContainer class:
var container = new ArgumentsContainer();
container.Add(new VideoCodecArgument(VideoCodec.LibX264));
container.Add(new ScaleArgument(VideoSize.Hd));
var ffmpeg = new FFMpeg();
var result = ffmpeg.Convert(container, new FileInfo("input.mp4"), new FileInfo("output.mp4"));Other availible arguments could be found in FFMpegSharp.FFMPEG.Arguments namespace.
If you need to create your custom argument, you just need to create new class, that is inherited from Argument, Argument<T> or Argument<T1, T2>
For example:
public class OverrideArgument : Argument
{
public override string GetStringValue()
{
return "-y";
}
