# FFMpegCore
[![NuGet Badge](https://buildstats.info/nuget/FFMpegCore)](https://www.nuget.org/packages/FFMpegCore/)
[![Build Status](https://travis-ci.org/vladjerca/FFMpegCore.svg?branch=master)](https://travis-ci.org/vladjerca/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.
## Binaries
If you prefer to manually download them, visit [ffbinaries](https://ffbinaries.com/downloads).
#### Windows
command: `choco install ffmpeg -Y`
location: `C:\ProgramData\chocolatey\lib\ffmpeg\tools\ffmpeg\bin`
#### Mac OSX
command: `brew install ffmpeg mono-libgdiplus`
location: `/usr/local/bin`
#### Ubuntu
command: `sudo apt-get install -y ffmpeg libgdiplus`
location: `/usr/bin`
## Path Configuration
#### Behavior
If you wish to support multiple client processor architectures, you can do so by creating a folder `x64` and `x86` in the `root` directory.
Both folders should contain the binaries (`ffmpeg.exe` and `ffprobe.exe`) for build for the respective architectures.
By doing so, the library will attempt to use either `/root/{ARCH}/(ffmpeg|ffprobe).exe`.
If these folders are not defined, it will try to find the binaries in `/root/(ffmpeg|ffprobe.exe)`
#### Option 1
The default value (`\\FFMPEG\\bin`) can be overwritten via the `FFMpegOptions` class:
```c#
public Startup()
{
FFMpegOptions.Configure(new FFMpegOptions { RootDirectory = "./bin" });
}
```
#### Option 2
The root directory for the ffmpeg binaries can be configured via the `ffmpeg.config.json` file.
```json
{
"RootDirectory": "./bin"
}
```
# Compatibility
Some versions of FFMPEG might not have the same argument schema. The lib has been tested with version `3.3` to `4.1`
# API
## 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";
}
}
```
