将阿拉伯语文本添加到视频 ffmpeg c#

问题描述

我想在视频中添加阿拉伯语注释或文本，我在 win 32 位中使用 ffmpeg 4.3.1 版，这里是我的 C# 代码：

private string AddVideo_Annotation(string text,int X,int Y)
        {
            try
            {

                string FFmpegPath = Utils.GetEXE_FFmpegPath();
                string path = Utils.GetProgramPath();
                //store outcome of process
                var errors = new StringBuilder();
                var output = new StringBuilder();
                var hadErrors = false;

                Process pdfprocess = new Process();

                
                //pdfprocess.StartInfo.LoadUserProfile = true;
                pdfprocess.StartInfo.RedirectStandardOutput = true;
                pdfprocess.StartInfo.RedirectStandardError = true;
                pdfprocess.StartInfo.UseShellExecute = false;
                
                pdfprocess.StartInfo.FileName = FFmpegPath;
                //text_shaping=1
                pdfprocess.StartInfo.Arguments = "-i \""+filePath+ "\" -vf -enable-libfribidi drawtext=\"text_shaping=1:text=\'" + text+ "\':x=" + X+":y="+Y+ ":fontsize=24:fontcolor=Red\"  -c:a copy \"" + path + "\\out.mp4\"";
               
                //pdfprocess.StartInfo.WorkingDirectory = @"C:\Program Files\LibreOffice\program\";
                pdfprocess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

                pdfprocess.EnableRaisingEvents = true;

                // capture normal output
                pdfprocess.OutputDataReceived += (s,d) => {
                    output.Append(d.Data);
                };

                // Capture error output
                pdfprocess.ErrorDataReceived += (s,d) => {
                    if (!hadErrors)
                    {
                        hadErrors = !String.IsNullOrEmpty(d.Data);
                    }
                    errors.Append(d.Data);
                };
                pdfprocess.Start();
                pdfprocess.BeginErrorReadLine();
                pdfprocess.BeginoutputReadLine();
                try
                {
                    while (pdfprocess.MainWindowHandle == IntPtr.Zero)
                    {
                        // discard cached information about the process
                        // because MainWindowHandle might be cached.
                        pdfprocess.Refresh();
                        
                        Thread.Sleep(200);

                    }
                }
                catch { }
                Thread.Sleep(2000);
                pdfprocess.WaitForExit();
                while ((Process.GetProcessesByName("ffmpeg").Length > 0))
                {
                    Thread.Sleep(200);
                }


                string stderr = errors.ToString();

                if (pdfprocess.ExitCode != 0)
                {
                    //MessageBox.Show("error:" + stderr);

                    throw new Exception("FFmpeg.exe has exit wit code " + pdfprocess.ExitCode+"\n"+ stderr);
                }
                return path + "\\out"+new FileInfo( filePath).Extension;
            }
            catch(Exception ex)
            {
                TXT_AnnotationText.Text = ex.Message + "\n" + ex.StackTrace.ToString();
                MessageBox.Show(ex.Message + "\n" + ex.StackTrace.ToString());
                throw ex;
            }
        }

我收到此错误消息：
