FFMPEG.exe output

Products: Video Capture SDK .Net, Video Edit SDK .Net

SDKs provide file output using FFMPEG.exe.

FFMPEG, a versatile and powerful multimedia framework, supports an extensive range of output formats, including but not limited to MP4, WebM, AVI, and WMV. It is renowned for its compatibility with a multitude of video and audio encoders, each providing a variety of customizable settings to cater to different encoding needs.

FFMPEG also seamlessly integrates with hardware encoders like Intel QuickSync, NVidia NVENC, and AMD AMF/VCE, enhancing its efficiency and performance in processing multimedia files.

The same sample code can be used for Video Edit SDK .Net. Use the VideoEditCore class instead of VideoCaptureCore.

Sample code​

Create FFMPEGEXEOutput object​

var ffmpegOutput = new FFMPEGEXEOutput();

Specify the output muxer (MP4, WebM, AVI, etc.)​

ffmpegOutput.OutputMuxer = OutputMuxer.MP4;

Apple video encoder settings​

var videoEncoder = new H264MFSettings();

// configure video encoder
// ...

ffmpegOutput.Video = videoEncoder;

Supported video encoder classes

  • H264AMFSettings (AMD GPU H264 encoder)
  • H264MFSettings (CPU H264 encoder)
  • H264NVENCSettings (Nvidia GPU H264 encoder)
  • H264QSVSettings (Intel QuickSync H264 encoder)
  • X264Settings (CPU H264 encoder)
  • HEVCAMFSettings (AMD GPU HEVC encoder)
  • HEVCNVENCSettings (Nvidia GPU HEVC encoder)
  • HEVCQSVSettings (Intel QuickSync HEVC encoder)
  • X265Settings (CPU HEVC encoder)
  • MPEG2Settings (MPEG-2 CPU encoder)

x264/x265 encoders can be used with alternative GPL FFMPEG builds that contain it.

Apply audio encode settings​

var audioEncoder = new BasicAudioSettings();

// configure audio encoder
audioEncoder.Bitrate = 192000;
audioEncoder.Channels = 2;
audioEncoder.SampleRate = 44100;
audioEncoder.Encoder = AudioEncoder.AAC;
audioEncoder.Mode = AudioMode.CBR;

ffmpegOutput.Audio = audioEncoder;

You can check the VisioForge.Core.Types.FFMPEGEXE.AudioEncoder enum for available audio encoders.

Set FFMPEG format settings for output

core.Output_Format = ffmpegOutput;

Set the video capture mode (or video convert mode if you use Video Edit SDK)

core.Mode = VideoCaptureMode.VideoCapture;

Set the file name (be sure that you have to write access rights)

core.Output_Filename = "output.mp4";

Start capture (or convert)

await core.StartAsync();

Required redists​

  • Video Capture SDK redist x86 x64
  • Video Edit SDK redist x86 x64 -FFMPEG EXE redist x86 x64

How can the required redists be installed or deployed to the user's PC?
