• Unrecognized option 'crf'

  6 septembre 2022, par Arjit Kaushal

  I am trying compress video using ffmpeg but i am facing errors in the command.
Although it runs perfectly fine on my linux terminal.( ffmpeg -i input.avi -vcodec libx264 -crf 24 output.avi).

  


  my code :

  


  void _compress() {
        if (_videoModel == null) return;
        String inputPath = _videoModel!.originalCachePath;
        String outputPath = _videoModel!.editCachePath;
    
        FFmpegKit.execute("-i $inputPath -vcodec libx264 -crf 24 -y $outputPath")
            .then((session) async {
          final returnCode = await session.getReturnCode();
          if (ReturnCode.isSuccess(returnCode)) {
            Navigator.pushNamed(context, PreviewPage.routeName,
                arguments: _videoModel);
          } else if (ReturnCode.isCancel(returnCode)) {
            print("compress cancel");
          } else {
            print("compress error : $returnCode");
            FFmpegKitConfig.enableLogCallback((log){
              final message = log.getMessage();
              print(message);
            });
    
    
          }
        });
      }


  


  I am facing the following errors :
Unrecognized option 'crf',
I/flutter (31056) : Error splitting the argument list,
Option not found.

  


• Option not found at ffmpeg

  28 décembre 2016, par AlphaWolf

  I tried to add watermark to a video using python by call subprocess ffmpeg. My code :

  command = "C:\\VidMaker\\source\\ffmpeg.win32.exe -i C:\\VidMaker\\kq"+str(i)+".mp4 -i C:\\VidMaker\\1.png -filter_complex" "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" "-vcodec libx264 C:\VidMaker\\Res"+str(i)+".mp4"
  
  subprocess.check_call(command, shell = False)

  the result is :

  Unrecognized option 'filter_complex[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7-movflags'.
  
  Error splitting the argument list: Option not found
  
  Traceback (most recent call last):
  
    File "C:\VidMaker\add.py", line 10, in <module>
  
      subprocess.check_call(command, shell = False)
  
    File "C:\Python27\lib\subprocess.py", line 186, in check_call
  
      raise CalledProcessError(retcode, cmd)
  
  subprocess.CalledProcessError: Command 'C:\VidMaker\source\ffmpeg.win32.exe -n -i C:\VidMaker\kq2.mp4 -i C:\VidMaker\1.png -filter_complex[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7-movflags +faststart C:\VidMaker\Res2.mp4' returned non-zero exit status 1
  
  [Finished in 0.4s with exit code 1]
  
  </module>

  edit1 : it run ok without option :

  command = "C:\\VidMaker\\source\\ffmpeg.win32.exe -i C:\\VidMaker\\kq"+str(i)+".mp4 -i C:\\VidMaker\\1.png -filter_complex overlay=10:10 C:\VidMaker\\Res"+str(i)+".mp4"

  What happen with the option and how can fix it ?Thanks !

  edit2 : i need to call like that because my VPS cannot run like my computer, in my computer it run successfully with :

   subprocess.call(['ffmpeg', 
  
    '-i', 'funvi 155.mp4',
  
    '-i', '1.png',
  
    '-filter_complex', "[1:v]format=argb,geq=r='r(X,Y)':a='0.15*alpha(X,Y)'[zork]; [0:v][zork]overlay", 
  
    '-vcodec', 'libx264',
  
    'myresult6.mp4'])

  libavfilter/vf_dnn_detect : Add model_type option.
  There are many kinds of detection DNN model and they have different
  
  preprocess and postprocess methods. To support more models,
  
  "model_type" option is added to help to choose preprocess and
  
  postprocess function.
