+
+# FFMpegCore [![NuGet Badge](https://buildstats.info/nuget/FFMpegCore)](https://www.nuget.org/packages/FFMpegCore/)
+
+## Setup
+
+#### NuGet:
+
+```
+Install-Package FFMpegCore
+```
+
+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.
+
+### FFProbe
+
+FFProbe is used to gather video information
+```csharp
+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:
+```csharp
+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 Mb
+```
+
+### FFMpeg
+Convert your video files to web ready formats:
+
+```csharp
+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:
+```csharp
+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:
+```csharp
+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:
+```csharp
+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:
+```csharp
+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:
+```csharp
+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:
+```csharp
+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):
+```csharp
+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:
+```csharp
+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();
+}
+```
+### Enums
+
+Video Size enumeration:
+
+```csharp
+public enum VideoSize
+{
+    HD,
+    FullHD,
+    ED,
+    LD,
+    Original
+}
+```
+
+Speed enumeration:
+
+```csharp
+public enum Speed
+{
+    VerySlow,
+    Slower,
+    Slow,
+    Medium,
+    Fast,
+    Faster,
+    VeryFast,
+    SuperFast,
+    UltraFast
+}
+```
+Audio codecs enumeration:
+
+```csharp
+public enum AudioCodec
+{
+        Aac,
+        LibVorbis
+}
+```
+
+Audio quality presets enumeration:
+
+```csharp
+public enum AudioQuality
+{
+        Ultra = 384,
+        Hd = 192,
+        Normal = 128,
+        Low = 64
+}
+```
+
+Video codecs enumeration:
+
+```csharp
+public enum VideoCodec
+{
+        LibX264,
+        LibVpx,
+        LibTheora,
+        Png,
+        MpegTs
+}
+```
+### ArgumentBuilder
+Custom video converting presets could be created with help of `ArgumentsContainer` class:
+```csharp
+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 `FFMpegCore.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:
+```csharp
+public class OverrideArgument : Argument
+{
+    public override string GetStringValue()
+    {
+        return "-y";
+    }
+}
+```
