• Pass individual frames as BGRA byte array and set the timestamps via pipe to FFmpeg

  30 juillet 2023, par Nicke Manarin

  I have a set of images (as BGRA byte[]) with their respective timestamps in milliseconds and I want to pass it to FFmpeg to build an animation.

  


  I'm using FFmpeg v6 right now and in this example I'm expecting a GIF as output, but I'm going to export to multiple formats later.

  


  var arguments = "-vsync passthrough  
-f rawvideo 
-pix_fmt bgra 
-video_size {width}x{height} 
-i -  
-loop 0 
-lavfi palettegen=stats_mode=diff[pal],[0:v][pal]paletteuse=new=1:dither=sierra2_4a:diff_mode=rectangle 
-f gif 
-y \"C:\Users\User\Desktop\test.gif\"";

var process = new Process
{
    StartInfo = new ProcessStartInfo
    {
        FileName = "./ffmpeg.exe",
        Arguments = arguments.Replace("{width}", width.ToString()).Replace("{height}", height.ToString()),
        RedirectStandardInput = true,
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true
    }
};

_process.Start();



  


  Then on my render loop, I'm trying to send the frames and their timestamps one by one.

  


  public void EncodeFrame(IntPtr bufferAddress, int bufferStride, int width, int height, int index, long timestamp, int delay)
{
    var frameSize = height * bufferStride;
    var frameBytes = new byte[frameSize];
    System.Runtime.InteropServices.Marshal.Copy(bufferAddress, frameBytes, 0, frameSize);

    _process.StandardInput.BaseStream.Write(frameBytes, 0, frameSize);
    _process.StandardInput.BaseStream.Write(_delimiter, 0, _delimiter.Length);
    _process.StandardInput.BaseStream.Write(BitConverter.GetBytes(timestamp), 0, sizeof(long));
}


  


  The issue is that I'm getting an IOException (The pipe has been ended), so probably I'm not sending the frames correctly (not sending the delimiter and timestamp doesn't help).

  


  Is this even possible ?
