ffmpeg.我更正要插入徽标 [英] ffmpeg. I correct that to insert the logo

问题描述

 私有  void  btnStart_Click(此 .btnStart.Enabled =  false ;
 此 .progressBar1.Value =  0 ;

 字符串 srcFile = Path.Combine( this  .txtSource.Text， this  .lstFiles.SelectedItem.ToString());
 MessageBox.Show(srcFile);
 字符串 dstFile = Path.Combine(此 .txtOutput.Text，
 Path.GetFileNameWithoutExtension( this  .lstFiles.SelectedItem.ToString()))+ "  + 字符串 imafile = Path.Combine(" +this.openFileDialog1.SafeFileName);
 MessageBox.Show(imafile);


            字符串 videoRateOption = 字符串 .Empty;
 如果(此 .cboVideoRate.SelectedIndex！=  0 )
 {
 videoRateOption = "  + >  .cboVideoRate.SelectedItem.ToString().Split(' ')["   k";
 MessageBox.Show(videoRateOption);
 }

 字符串 videoSizeOption = 字符串 .Empty;
 如果(此 .lstVideoSize.SelectedIndex！=  0 )
 {
 videoSizeOption = "  + 此 .lstVideoSize.SelectedItem.ToString().Split(' ')["  ";
 }


            此 .Text = " ;
 ThreadPool.QueueUserWorkItem((对象状态)= > 
 {
 ConvertFile(srcFile，imafile，dstFile，videoRateOption，videoSizeOption);
 });
 }


字符串 strFFMPEGOut;
 ProcessStartInfo psiProcInfo = 新 ProcessStartInfo();
 TimeSpan估计时间= TimeSpan.MaxValue;

 StreamReader srFFMPEG;

                字符串 ste = "  movie = watermarklogo .png [wm]; [在中] [wm] overlay = main_w-overlay_w-10:main_h-overlay_h-10 [ out ] " ;
 字符串 strFFMPEGCmd = "  "  "  -ar 44100" + videoRateOption + videoSizeOption +  -vf" span> + ste + "  " 
 + dstFile +"  ";

 psiProcInfo.FileName = Application.StartupPath +(( IntPtr  .Size ==  8 )?" :" )+ " ;
 psiProcInfo.Arguments = strFFMPEGCmd;
 psiProcInfo.UseShellExecute =  false ;
                psiProcInfo.WindowStyle = ProcessWindowStyle.Hidden;
 psiProcInfo.UseShellExecute =  false ;
 psiProcInfo.RedirectStandardError =  true ;
 psiProcInfo.ErrorDialog =  true ;
 psiProcInfo.RedirectStandardOutput =  true ;
 psiProcInfo.CreateNoWindow =  true ;

 prcFFMPEG.StartInfo = psiProcInfo;

 prcFFMPEG.Start(); 

我没有按下启动按钮来尝试修复使用Ffmpeg将徽标插入影片中的代码时的响应.如果我不选择徽标文件的路径，那可以吗?

解决方案

请不要在多个论坛中重新发布相同的问题.您已经在此处了一个答案 [

private void btnStart_Click(object sender, EventArgs e)
 {
 this.btnStart.Enabled = false;
 this.progressBar1.Value = 0;

 string srcFile = Path.Combine(this.txtSource.Text, this.lstFiles.SelectedItem.ToString());
 MessageBox.Show(srcFile);
 string dstFile = Path.Combine(this.txtOutput.Text,
 Path.GetFileNameWithoutExtension(this.lstFiles.SelectedItem.ToString())) + "." + this.cboOutputFormat.SelectedItem;
 MessageBox.Show(dstFile);
 string imafile = Path.Combine("movie= "+this.openFileDialog1.SafeFileName);
 MessageBox.Show(imafile);


            string videoRateOption = string.Empty;
 if (this.cboVideoRate.SelectedIndex != 0)
 {
 videoRateOption = " -b:v " + this.cboVideoRate.SelectedItem.ToString().Split(' ')[0] + "k ";
 MessageBox.Show(videoRateOption);
 }

 string videoSizeOption = string.Empty;
 if (this.lstVideoSize.SelectedIndex != 0)
 {
 videoSizeOption = " -s " + this.lstVideoSize.SelectedItem.ToString().Split(' ')[0] + " ";
 }


            this.Text = "Converting...";
 ThreadPool.QueueUserWorkItem((object state) =>
 {
 ConvertFile(srcFile, imafile, dstFile, videoRateOption, videoSizeOption);
 });
 }


string strFFMPEGOut;
 ProcessStartInfo psiProcInfo = new ProcessStartInfo();
 TimeSpan estimatedTime = TimeSpan.MaxValue;

 StreamReader srFFMPEG;

                string ste = ""movie=watermarklogo.png [wm];[in][wm] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]"";
 string strFFMPEGCmd = " -i "" + srcFile + "" -ar 44100 " + videoRateOption + videoSizeOption +"-vf"+ ste + "-y ""
 + dstFile + """;

 psiProcInfo.FileName = Application.StartupPath + ((IntPtr.Size == 8) ? "\x64" : "\x86") + "\ffmpeg.exe";
 psiProcInfo.Arguments = strFFMPEGCmd;
 psiProcInfo.UseShellExecute = false;
                psiProcInfo.WindowStyle = ProcessWindowStyle.Hidden;
 psiProcInfo.UseShellExecute = false;
 psiProcInfo.RedirectStandardError = true;
 psiProcInfo.ErrorDialog = true;
 psiProcInfo.RedirectStandardOutput = true;
 psiProcInfo.CreateNoWindow = true;

 prcFFMPEG.StartInfo = psiProcInfo;

 prcFFMPEG.Start();

There is no response that I push the start button that I tried to fix the code that I inserted the logo in the movie with Ffmpeg. Is that be okay if I don''t choose the path of logo File. and Is there any something wrong that I did.
