• Render Multiple Gifs with ffplay/ffmpeg in Winform

  17 juin 2019, par Purqs

  I’m trying to get x number of animated gifs to render on like a Panel or PictureBox and using transparency that is in each gif. I’ve tried a couple approaches but am not super famiular with ffmpeg and such. Below is some code that I use to get it to render inside a panel, but I can’t figure out how to get like 5 gifs to stack/layer on one another and still render as you would expect.

  I need/want this to render in the form and not outputted. I am a little confused to why the ffplay.exe doesn’t use the -i command and that might be why i can’t get it to render. any ideas ?

  Working example below.

  using System;
  
  using System.Collections.Generic;
  
  using System.ComponentModel;
  
  using System.Data;
  
  using System.Drawing;
  
  using System.Linq;
  
  using System.Text;
  
  using System.Threading.Tasks;
  
  using System.Windows.Forms;
  
  using System.Diagnostics;
  
  using System.Threading;
  
  using System.IO;
  
  using System.Reflection;
  
  using System.Runtime.InteropServices;
  
  using System.Drawing.Text;
  
  using System.Text.RegularExpressions;
  
  using System.Configuration;
  
  using Microsoft.Win32;
  
  using System.Windows.Forms.VisualStyles;
  
  
  
  //FOR THIS EXAMPLE CREATE FORM HAVE BUTTON ON IT AND PANEL.
  
  //button: button's click is "button1_Click"
  
  //panel: Needed to output the render on it.
  
  //FILES:
  
  //Test.Gif
  
  //These ff files came from the ffmpeg offical site.
  
  //ffplay.exe //currently using
  
  //ffmpeg.exe //thinking i need to use to get it how I want.
  
  //I most of the code below from https://stackoverflow.com/questions/31465630/ffplay-successfully-moved-inside-my-winform-how-to-set-it-borderless which was a good starting point.
  
  
  
  namespace Test_Form
  
  {
  
      public partial class Form1 : Form
  
      {
  
          [DllImport("user32.dll", SetLastError = true)]
  
          private static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);
  
  
  
          [DllImport("user32.dll")]
  
          private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
  
  
  
  
  
          //Process ffplay = null;
  
  
  
          public Form1()
  
          {
  
              InitializeComponent();
  
              Application.EnableVisualStyles();
  
              this.DoubleBuffered = true;
  
          }
  
  
  
  
  
  
  
          public Process ffplay = new Process();
  
          private void FFplay()
  
          {
  
              ffplay.StartInfo.FileName = "ffplay.exe";
  
              ffplay.StartInfo.Arguments = "-noborder Test.gif"; //THIS IS WHERE I INPUT THE GIF FILE
  
              ffplay.StartInfo.CreateNoWindow = true;
  
              ffplay.StartInfo.RedirectStandardOutput = true;
  
              ffplay.StartInfo.UseShellExecute = false;
  
  
  
              ffplay.EnableRaisingEvents = true;
  
              ffplay.OutputDataReceived += (o, e) => Debug.WriteLine(e.Data ?? "NULL", "ffplay");
  
              ffplay.ErrorDataReceived += (o, e) => Debug.WriteLine(e.Data ?? "NULL", "ffplay");
  
              ffplay.Exited += (o, e) => Debug.WriteLine("Exited", "ffplay");
  
              ffplay.Start();
  
  
  
              Thread.Sleep(1000); // you need to wait/check the process started, then...
  
  
  
              // child, new parent
  
              // make 'this' the parent of ffmpeg (presuming you are in scope of a Form or Control)
  
              SetParent(ffplay.MainWindowHandle, this.Handle);
  
  
  
              // window, x, y, width, height, repaint
  
              // move the ffplayer window to the top-left corner and set the size to 320x280
  
              MoveWindow(ffplay.MainWindowHandle, 800, 600, 320, 280, true);
  
  
  
              SetParent(ffplay.MainWindowHandle, this.panel1.Handle);
  
              MoveWindow(ffplay.MainWindowHandle, -5, -30, 320, 280, true);
  
          }
  
  
  
  //runs the FFplay Command
  
  private void button1_Click(object sender, EventArgs e)
  
          {
  
              FFplay();
  
  
  
          }
  
  
  
          private void Form1_FormClosed(object sender, FormClosedEventArgs e)
  
          {
  
              try { ffplay.Kill(); }
  
              catch { }
  
          }
  
      }

  I would like the button to allow me to add any number of gifs (like 5 or 10) all to the same area and have them being animated with their transparent showing what is under that gif.

  So for example I could have a circle image, then a spinning/loading transparent gif on top, and then a gif that counts up/down on top of that one to give me the effect of a count-down.

  Thanks for all the help !
