A .NET Standard FFMpeg/FFProbe wrapper for easily integrating media analysis and conversion into your .NET applications. Supports both synchronous and asynchronous calls
# API
## FFProbe
FFProbe is used to gather media information:
Use FFProbe to analyze media files:
```csharp
var mediaInfo = FFProbe.Analyse(inputPath);
var mediaInfo = await FFProbe.AnalyseAsync(inputPath);
```
or
```csharp
var mediaInfo = await FFProbe.AnalyseAsync(inputPath);
var mediaInfo = FFProbe.Analyse(inputPath);
```
## FFMpeg
FFMpeg is used for converting your media files to web ready formats.
Use FFMpeg to convert your media files.
Easily build your FFMpeg arguments using the fluent argument builder:

### 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 being generated or received.
## 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 for converting video on-the-fly while frames are being generated or received.
The `IPipeSource` interface is used as the source of data. It could be represented as encoded video stream or raw frames stream. Currently, the `IPipeSource` interface has single implementation, `RawVideoPipeSource` that is used for raw stream encoding.
An object implementing the `IPipeSource` interface is used as the source of data. Currently, the `IPipeSource` interface has two implementations; `StreamPipeSource` for streams, and `RawVideoPipeSource` for raw video frames.
For example:
### Working with raw video frames
Method that is generating bitmap frames:
Method for generating bitmap frames:
```csharp
IEnumerable<IVideoFrame> CreateFrames(int count)
{
for(int i = 0; i < count; i++)
{
yield return GetNextFrame(); //method of generating new frames
yield return GetNextFrame(); //method that generates of receives the next frame
}
}
```
Then create `ArgumentsContainer` with `InputPipeArgument`
Then create a `RawVideoPipeSource` that utilises your video frame source
```csharp
var videoFramesSource = new RawVideoPipeSource(CreateFrames(64)) //pass IEnumerable<IVideoFrame> or IEnumerator<IVideoFrame> to constructor of RawVideoPipeSource
var videoFramesSource = new RawVideoPipeSource(CreateFrames(64))
{
FrameRate = 30 //set source frame rate
};

## Binaries
# Binaries
## Installation
If you prefer to manually download them, visit [ffbinaries](https://ffbinaries.com/downloads) or [zeranoe Windows builds](https://ffmpeg.zeranoe.com/builds/).
#### Windows
command: `choco install ffmpeg -Y`
### Windows (using choco)
command: `choco install ffmpeg -y`
location: `C:\ProgramData\chocolatey\lib\ffmpeg\tools\ffmpeg\bin`
#### Mac OSX
### Mac OSX
command: `brew install ffmpeg mono-libgdiplus`
location: `/usr/local/bin`
#### Ubuntu
### 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
### Option 1
The default value of an empty string (expecting ffmpeg to be found through PATH) can be overwritten via the `FFOptions` class:
```c#
```csharp
// setting global options
GlobalFFOptions.Configure(new FFOptions { BinaryFolder = "./bin", TemporaryFilesFolder = "/tmp" });
// or
GlobalFFOptions.Configure(options => options.BinaryFolder = "./bin");
// on some systems the absolute path may be required, in which case
GlobalFFOptions.Configure(new FFOptions { BinaryFolder = Server.MapPath("./bin"), TemporaryFilesFolder = Server.MapPath("/tmp") });

### Supporting both 32 and 64 bit processes
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)`.
(`.exe` is only appended on Windows)
# Compatibility
Some versions of FFMPEG might not have the same argument schema. The lib has been tested with version `3.3` to `4.2`
Older versions of ffmpeg might not support all ffmpeg arguments available through this library. The library has been tested with version `3.3` to `4.2`
