How can I read System.Drawing.Bitmaps from a video file using FFMpegCore ?
18 avril 2021, par David SacksteinI am using https://github.com/rosenbjerg/FFMpegCore to write System.Drawing.Bitmaps to a video file and to read them back as bitmaps.


Based on the examples I was able to implement the first step as so :


public static void WriteToH264(System.Drawing.Bitmap[] bitmaps, string fileName)
{
 Directory.CreateDirectory(Path.GetDirectoryName(fileName)!);

 WriteToH264(
 bitmaps.Select(bitmap => new BitmapVideoFrameWrapper(bitmap)), 
 4, 
 fileName);
}

private static void WriteToH264(IEnumerable<ivideoframe> bitmaps, int frameRate, string fileName)
{
 var videoFramesSource = new RawVideoPipeSource(bitmaps)
 {
 FrameRate = frameRate
 };
 
 FFMpegArguments
 .FromPipeInput(videoFramesSource)
 .OutputToFile(fileName, true, options => options
 .WithVideoCodec(VideoCodec.LibX264))
 .ProcessSynchronously();
}
</ivideoframe>

For the second part I need to implement the following function using the same library :


public static System.Drawing.Bitmap[] ReadFromH264(string fileName)


But I have not find an samples of how to do this.


How should I implement this function ?
