Create media info object

FFMediaInfo info = new FFMediaInfo("/path/to/media.mkv");

Create Muxed converter

FFMuxedConverter converter = FFMuxedConverter.SetMedia(info)

.ChangeAudioBitrate("200K")

Changes the hardware acceleration method

.ChangeHardwareAccelerationMethod()

Changes the pixel format of the video

.ChangePixelFormat("y2k")

Changes the width and height of the video stream

.ChangeResolution(800, 600)

Changes the width of the video while maintaining aspect ratio

.ChangeWidth(800)

Changes the height of the video while maintaining aspect ratio

.ChangeHeight(600)

The position that the video starts at

.ChangeStartPosition("00:00:00")

Events

/// The console output of ffmpeg
DataReceivedEventHandler? data_handler = (object s, DataReceivedEventArgs e) => { };

/// Runs when ffmpeg exists
EventHandler exited = (object sender, EventArgs e) => { };

/// Returns ffmpeg update values
EventHandler<FFProcessUpdateEventArgs> updated = (object sender, FFProcessUpdateEventArgs e) =>
{
    /// The bitrate that the video is being processed at
    float bitrate = e.AverageBitrate;

    /// The number of frames already processed
    uint frames = e.FramesProcessed;

    /// The percentage of the video has been processed
    float percentage = e.Percentage;

    /// The speed that the video is processing at
    float speed = e.Speed;
};

Converts the current Muxed Converter

.Convert("/path/to/output.mkv", data_handler, exited, updated);

Builds a ffmpeg argument string

.Build("/path/to/output.mkv")

Example

string argument = FFMuxedConverter
    .SetMedia(info)
    .ChangeVideoCodec("h264_nvenc")
    .ChangeVideoBitrate("2M")
    .ChangeHardwareAccelerationMethod()
    .ChangeResolution(800, 600)
    .OverwriteOriginal()
    .Build("/path/to/output.mkv");

FFProcessHandler.ExecuteFFmpeg(argument, data_handler, exited, updated);
