• Flutter FFmpeg | Concat Multiple Videos From TXT File And Save As A Video

  7 mai 2023, par Muhammad Hassan

  I have a text file with all path of video files that I want to concat using
https://pub.dev/packages/ffmpeg_kit_flutter in my flutter app.

  


  For this purpose, I write a file my_file.txt with the below data...

  


  /data/user/0/com.example.video_merger/cache/75f72300-1203-4e2c-93cf-65777152f1d16524788775537818173.mp4
/data/user/0/com.example.video_merger/cache/318d5ea7-3e0c-4453-903b-06966aa86f348487775694692938421.mp4


  


  Now I am using the below code to merge all the upper videos.

  


  String outputPath = "/data/user/0/com.example.video_merger/app_flutter/output.mp4";
String commandToExecute = '-f concat -i $rawDocumentPath/my_file.txt -c copy $outputPath';
FFmpegKit.execute(commandToExecute).then((session) async {
  final returnCode = await session.getReturnCode();
  print("FFmpeg Process Exited With ReturnCode = $returnCode");
  GallerySaver.saveVideo(outputPath).then((_) {
    print("Merged Video Saved");
  });
  if (ReturnCode.isSuccess(returnCode)) {
    // SUCCESS
  } else if (ReturnCode.isCancel(returnCode)) {
    // CANCEL
  } else {
    // ERROR
  }
});


  


  But it is giving me error as shown below...

  


  FFmpeg Process Exited With ReturnCode = 1 
E/GallerySaver(31493): /data/user/0/com.example.video_merger/app_flutter/output.mp4: open failed: ENOENT (No such file or directory)


  


  But when I use the below ffmpeg command directly without reading from text file works fine and save my video.

  


  String commandToExecute = '-y -i ${_storedVideoOne!.path} -i ${_storedVideoTwo!.path} -r 24000/1001 -filter_complex \'[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[out]\' -map \'[out]\' $outputPath';


  


  Now my question is that I will have dynamic number of videos to concat so I want to use text file where I will write all paths then will make merged video from them. So what is the error in my ffmpeg command...???

  


  Log Report :

  


  I used the log reporting as follows to get the below output of errors...

  


      FFmpegKit.executeAsync(
      commandToExecute2,
          (session) async {
            final returnCode = await session.getReturnCode();
            print("FFmpeg Process Exited With ReturnCode = $returnCode");
            GallerySaver.saveVideo(outputPath).then((_) async {
              print("Merged Video Saved");
            });
            if (ReturnCode.isSuccess(returnCode)) {
              // SUCCESS
            } else if (ReturnCode.isCancel(returnCode)) {
              // CANCEL
            } else {
              // ERROR
            }
          },
          (log) {
        print("XXXXXXXXXXXX fFmpeg XXXXXXXXXX ${log.getMessage()}");
      },
    );


  


  And here is the Log Output...

• ffmpeg error "No such file or directory" while compiling a video file compression

  13 janvier 2016, par Abraham Gharyali

  Firstly I have checked many questions and answers related to my question, but unfortunately none of them solves my problem.

  I have implemented ffmpeg library in my project, using it for 2 tasks :

  1). adding watermark on video.

  2). video compression.

  I am able to apply watermark on recorded video successfully using this command :

  {"-y" ,"-i", "/storage/emulated/0/Booms/Videos/video1122150738.mp4","-strict","experimental", "-vf", "movie="
  
  + watermarkFile + " [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s", "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/storage/emulated/0/Shared/Videos/video.mp4"}

  "watermarkFile" is the location of .png watermark file

  Now I need to compress video, for that i used this command :

  "ffmpeg -i "+"/storage/emulated/0/Booms/Videos/video1122150738.mp4"+" -vcodec mpeg4 -s 320x240 -r 25 -y "+"/storage/emulated/0/Shared/Videos/video.mp4";

  It gives error "No such file or directory". please see the logs.

  01-11 15:32:55.663 28027-28027/ D/FFMPEG compress: Finished.

  for both operations i input .mp4 file and need .mp4 file in output.

  Same process works for watermarking and not working for compression.

  My compress command is correct because I checked the same command compressing video in my windows pc using command prompt.

  I don’t understand what i am doing wrong.

  Any help would be appreciated.
