ImageSharp.AVCodecFormats
FFmpeg decoders for ImageSharp
Install
via NuGet:
PM> Install-Package ImageSharp.AVCodecFormats
Native libs for x64 Linux and Windows:
PM> Install-Package ImageSharp.AVCodecFormats.Native
also, we can install separate native packages:
PM> Install-Package ImageSharp.AVCodecFormats.Native.win-x64
PM> Install-Package ImageSharp.AVCodecFormats.Native.linux-x64
Without native packages you should provide your own shared FFmpeg build and set path:
FFmpegBinaries.Path = "/path/to/native/binaries"
On Linux you have another way to get native libs. Just install ffmpeg from your package manager, but I have no guarantees that it will work as expected.
Usage
using System.IO;
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Formats.Jpeg;
using SixLabors.ImageSharp.Processing;
using HeyRed.ImageSharp.AVCodecFormats;
// Create custom configuration with all available decoders
var configuration = new Configuration().WithAVDecoders();
// Or only required decoders
var configuration = new Configuration(
new AviConfigurationModule(),
new MkvConfigurationModule(),
new MovConfigurationModule(),
new Mp4ConfigurationModule(),
new WebmConfigurationModule(),
new WmvConfigurationModule(),
new MpegTsConfigurationModule(),
new Mp3ConfigurationModule());
// NOTE: Don't forget to set max frames.
// Without this limit you can run into huge memory usage.
var decoderOptions = new DecoderOptions
{
MaxFrames = 50,
Configuration = configuration,
// The TargetSize option is also supported.
// This will reduce memory usage in result image.
};
using var inputStream = File.OpenRead("/path/to/video.mp4");
using var image = Image.Load(decoderOptions, inputStream);
// Resize
image.Mutate(x => x.Resize(image.Width / 2, image.Height / 2));
// Save all frames using png encoder
for (int i = 0; i < image.Frames.Count; i++)
{
image.Frames
.CloneFrame(i)
.SaveAsPng($"frame{i}.png");
}

Frame filter
Frame filter is a delegate that provides the way to skip frames based on their content.
It can be useful for various scenarios like black/white frames filter, skip every n frame or something else.
var decoderOptions = new AVDecoderOptions
{
GeneralOptions = new DecoderOptions
{
MaxFrames = 100,
},
FrameFilter = (imageFrame, frameNum) =>
{
var frame = (ImageFrame<Rgba32>)frame; // Pix format should match with Load/Decode methods
// Do something with frame
// Return true when frame should be not present in result image
return false;
},
};
using var inputStream = File.OpenRead(/path/to/video.mp4);
using var image = Mp4Decoder.Instance.Decode(decoderOptions, inputStream);
// do something
See tests for basic implementation of black frames filter.
Additional tips
If you want preserve aspect ratio when TargetSize is set:
var decoderOptions = new AVDecoderOptions
{
PreserveAspectRatio = true,
GeneralOptions = new DecoderOptions
{
TargetSize = new Size(500),
},
};
An additional format specific information about the file:
// Get infogmation about webm file
AVMetadata metadata = Image.Identify(decoderOptions, inputStream).Metadata.GetWebmMetadata();
Supported formats
mp4, webm, avi, mkv, mov, ts, wmv, mp3(cover image).
Supported codecs
Native package provides codecs listed below:
H263, H264, H.265(HEVC), VP8, VP9, AV1, MPEG-4, MJPEG, PNG, MS MPEG4(v1,v2,v3), WMV(v1,v2,v3), VC-1, MPEG-1 Audio Layer 3.
