• Error finding watermark path using ffmpeg in asp.net application

  27 août 2013, par irfanmcsd

  I am using .net ffmpeg wrapper to post watermark on videos. Posting watermark works fine if i execute ffmpeg command directly but failed to find suitable watermark png file location if command executed via asp.net application.

  here is sample ffmpeg command

  string RootPath = HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath);
  
  _mhandler.FFMPEGPath = RootPath + "/ffmpeg_aug_2013/bin/ffmpeg.exe";
  
  _mhandler.InputPath = RootPath + "/contents/original";
  
  _mhandler.OutputPath = RootPath + "/contents/mp4";
  
  _mhandler.BackgroundProcessing = false;
  
  _mhandler.FileName = "wildlife.wmv";
  
  _mhandler.OutputFileName = "wildlife_ddd";
  
  string presetpath = RootPath + "/ffmpeg_aug_2013/presets/libx264-ipod640.ffpreset";
  
  _mhandler.OutputExtension = ".mp4";
  
  _mhandler.Parameters = "-s 640x380 -b:v 500k -bufsize 500k -b:a 128k -ar 44100 -c:v libx264 -vf \"movie = watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]\"";
  
  _mhandler.Parameters = _mhandler.Parameters + " -fpre \"" + presetpath + "\"";
  
  VideoInfo info =  _mhandler.Process();

  i tried direct code too

  string _out = "";
  
  Process _process = new Process();
  
  _process.StartInfo.UseShellExecute = false;
  
  _process.StartInfo.RedirectStandardInput = true;
  
  //_process.StartInfo.RedirectStandardOutput = true;
  
  _process.StartInfo.RedirectStandardError = true;
  
  _process.StartInfo.CreateNoWindow = true;
  
  _process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  _process.StartInfo.FileName = _ffmpegpath;
  
  _process.StartInfo.Arguments = cmd;
  
  if (_process.Start())
  
  {             
  
      _process.WaitForExit(ExitProcess);
  
      _out = _process.StandardError.ReadToEnd();
  
      if (!_process.HasExited)
  
        _process.Kill();
  
  
  
      return _out;
  
   }

  Error on point ( Could find no file with path 'watermark.png' ) shows watermark.png file not found.
  I place watermark.png file in the following locations but still can't found

  i : application root

  ii : root where actual aspx page located

  iii : ffmpeg root

  iv : ffmpeg/bin/

  I also used complete path but still can't detected.

  Note : if i use same ffmpeg command in php and place watermark.png on location where actual php page exist watermark properly detected and command executed properly, but same approach not working in asp.net

  Can any one help me where should i place watermark.png file so that script can access it.

• ffmpeg convert video in a path with different name

  16 mars 2019, par tour travel

  Using ffmpeg in php with shell_exec and want to convert video in a path that different with where script is run. php script is in /s/m/video.php :

  <?php
  
  if(isset($_GET["videoTools"])){
  
  
  
      $user = $_GET["user"];
  
      $uid = $_GET["uid"];
  
      $vid = $_GET["vid"];
  
  
  
      $uploaddir = '/seller/uploads/'.$user.'/'.$uid.'/';
  
  
  
      echo shell_exec('ffmpeg -i '.$uploaddir.$vid.'-vid.mp4 -i /s/m/logo.png \
  
      -filter_complex "hflip[flipped];[flipped]overlay=x=20:y=20" \
  
      -s 480x320 -acodec aac -strict -2 -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 \
  
      -strict -2 '.$uploaddir.$vid.'-vid-resized.mp4');
  
  }
  
  ?>

  And this script called by ajax in /s/a/index.php :

      $.ajax({
  
          url: "/s/m/video.php?videoTools",
  
          type: "GET",
  
          data: {vid: json[0], uid: json[1], user: json[2]},
  
          success: function(data){
  
           // success
  
          }
  
      });

  And for example I want to convert video in this path /s/uploads/91/768/2019-2-2_668-vid.mp4

  Problems :

  This not working, because look like ffmpeg not find video and logo in a path / Also look like ffmpeg not accepet video with - or _ or etc.

  No related error log, but video not generated and script not working. Any idea ?

• How to correctly specify the path to a file in -vf media ?

  15 juillet 2024, par Wintreist

  Good afternoon, please, I really need help.
I'm putting a watermark on the video :

  


  with tempfile.TemporaryFile("wb", delete=False, suffix=".png") as watermark_file:
    watermark_file.write(buff.read())
(
    ffmpeg
    .input(str(path))
    .output(
        os.environ.get("TEMP")+f"\\{uuid.hex}_{path.name}",
        vf=f"movie='{watermark_file.name}' [watermark]; [in][watermark] overlay='{overlay}' [out]"
    )
    .global_args('-copyts')
    .run()
)


  


  In a temporary folder, I create a file in which I write a watermark from io.BytesIO
using the ffmpeg-python library, I do not work directly with the console.

  


  The problem is that when running .run() to the console outputs the following :

  


  [Parsed_movie_0 @ 0000011b21b3e300] Failed to avformat_open_input 'C'
[AVFilterGraph @ 0000011b21b4d4c0] Error initializing filters
[vost#0:0/libvpx-vp9 @ 0000011b23a07500] Error initializing a simple filtergraph
Error opening output file C:\Users\smeta\AppData\Local\Temp\5e5a695966cf4d728edbd7f39c509d0e_000.webm.
Error opening output files: No such file or directory


  


  But if I copy a watermarked file from temp and upload it to the workspace :
vf=f"movie='{'test.png'}' [watermark]; [in][watermark] overlay='{overlay}' [out]"
then everything works as it should. I.e. apparently there is a problem with the path to the watermark, and I do not understand what to do.
I ask for help
