# 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.
|
|
|
|
## 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:
|
|

|
|
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",
|
|

|
|
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 `ArgumentContainer` class:
|
|
```csharp
|
|
var container = new ArgumentContainer();
|
|
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.Argument` 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";
|
|
}
|
|
}
|
|
```
|
|
### Input piping
|
|
With input piping it is possible to write video frames directly from program memory without saving them to jpeg or png and then passing path to input of ffmpeg. This feature also allows us to convert video on-the-fly while frames are beeing generated/created/processed.
|
|
|
|
`IPipeSource` interface is used as source of data. It could be represented as encoded video stream or raw frames stream. Currently `IPipeSource` interface has single implementation, `RawVideoPipeSource` that is used for raw stream encoding.
|
|
|
|
For example:
|
|
|
|
Method that is generate bitmap frames:
|
|
```csharp
|
|
IEnumerable<IVideoFrame> CreateFrames(int count)
|
|
{
|
|
for(int i = 0; i < count; i++)
|
|
{
|
|
yield return GetNextFrame(); //method of generating new frames
|
|
}
|
|
}
|
|
```
|
|
Then create `ArgumentsContainer` with `InputPipeArgument`
|
|
```csharp
|
|
var videoFramesSource = new RawVideoPipeSource(CreateFrames(64)) //pass IEnumerable<IVideoFrame> or IEnumerator<IVideoFrame> to constructor of RawVideoPipeSource
|
|
{
|
|
FrameRate = 30 //set source frame rate
|
|
};
|
|
var container = new ArgumentsContainer
|
|
{
|
|
new InputPipeArgument(videoFramesSource),
|
|
... //Other encoding arguments
|
|
new OutputArgument("temporary.mp4")
|
|
};
|
|
|
|
var ffmpeg = new FFMpeg();
|
|
var result = ffmpeg.Convert(arguments);
|
|
```
|
|
|
|
if you want to use `System.Drawing.Bitmap` as `IVideoFrame`, there is `BitmapVideoFrameWrapper` wrapper class.
