• No such file or directory error in flutter_ffmpeg

  8 septembre 2021, par Aryan Shandilya

  I intend to use the flutter_ffmpeg package to convert audio to video with the image as a background, but I am encountering a very weird error. Despite the fact that the files exist in the location that I have provided to the flutter_ffmpeg package as input, I am getting a 'No such file or directory' error. I have already tested out everything I can thnk of but I just don't get it.

  


  Future<string> converter(String audioPath, String imagePath) async {&#xA;String? videoPath;&#xA;Directory? dir = await getExternalStorageDirectory();&#xA;// videoPath = dir!.path;&#xA;final videoDirectory = &#x27;${dir!.path}/VDir&#x27;;&#xA;if (await Directory(videoDirectory).exists() == false) {&#xA;  await Directory(videoDirectory).create();&#xA;}&#xA;// await Directory(videoDirectory).create();&#xA;videoPath = videoDirectory &#x2B; &#x27;/${DateTime.now().millisecond}.mp4&#x27;;&#xA;print(&#xA;    "-------------------------------------------------------------------------------------------------------------------------------------------------------------------");&#xA;print("\nAudioPath = " &#x2B; audioPath);&#xA;print("\nImagePath = " &#x2B; imagePath);&#xA;print("\nVideoPath = " &#x2B; videoPath);&#xA;print("\nVideoDirectory = " &#x2B; videoDirectory);&#xA;print(&#xA;    "\n-------------------------------------------------------------------------------------------------------------------------------------------------------------------");&#xA;_flutterFFmpeg&#xA;    .execute(&#xA;        &#x27;-loop 1 -framerate 2 -i \&#x27;$imagePath\&#x27; -i \&#x27;$audioPath\&#x27; -vf "scale=2*trunc(iw/2):2*trunc(ih/2),setsar=1" -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a copy -shortest -pix_fmt yuv420p $videoPath&#x27;)&#xA;    .catchError((onError) {&#xA;  print(onError);&#xA;  // ErrorHandler().errorDialog(context, )&#xA;});&#xA;return videoPath;}&#xA;</string>

  


  videoPath = await FFmpegOperations().converter(widget.audioPath, coverImagePath);

  


  Can someone tell me what is wrong with my code, I am using the min-gpl version(not lts) ffmpeg and am testing this on two android devices I am getting the same results.

  


  Error :
/data/user/0/com.example.example/app_flutter/datte.png : No such file or directory
D/flutter-ffmpeg( 1139) : FFmpeg exited with rc : 1
.
Any form of help would be more than welcome, thank you.

  


• Inotifywait giving wrong file path after running ffmpeg

  23 mars 2019, par Morpheus

  So im running a little inotifywait script to monitor a folder for new files and transcode them if they are mxf and contain a video stream. But for some weird reason if the script does call ffmpeg the next fileevent by inotify is giving me a wrong path seemingly random cutting the filepath at any position.

  So far i tried moving the call to an external script, resetting the file variable which shouldnt matter anyway and adding a sleep to the script. I also tried using normal filepaths without whitespaces or - which shouldnt matter but that also didnt help.

  inotifywait -m -r -e close_write -e moved_to --format "%w%f"  "$dir" | while read f 
  
  
  
  do
  
              if ffprobe "$file" 2>&1 | egrep 'Stream #0:0: Video' && ffprobe "$file" 2>&1 | egrep 'MXF' ; then
  
                  mkdir -vp "$movepath" && mkdir -vp "$trans$path3"  && mkdir -vp "$trans2$path3" && mv -fu "$f" "$trans2$path" && \
  
                  ffmpeg -y -i "$file" -map_metadata 0 -c:v h264_nvenc -b:v 2m -bufsize 2m -profile:v baseline -level:v 3.0 -pix_fmt yuv420p -vf yadif,scale="iw/4:ih/4" -an "$transpath" 2>> copy_ffmpeg_log.txt
  
  done

  expected :

  /media/raid/TMO_Media/INGEST-HP.1/WacinS1_19V01.5C935C93A3B4V.mxf

  example for an result after transcode :

  cinS1_19A06.5C935C93A088A.mxf

  do while normal mv commands work and inotify does work as expected when stopped for transcoding a file the next path given by inotify is getting messed up

• Ffmpeg behaving intermittently

  10 mars 2024, par confused

  I'm noticing something weird, for the first time ever today, and I'm not sure what the problem could even possibly be.

  


  I first noticed it while stripping videos with a python script I wrote. Now I realize it is even happen with command line entry.

  


  Some, but not all videos, and some but not all segments within the same video are not stripping correctly. I'm taking numerous 1-2 hour long videos and cutting segments out of it. When I go to look at the video clip afterwards it automatically jumps to 2, 5, 8, 10 seconds into the video and starts playing there. It depends on the video segment as to how far ahead it skips. If I try to get it to go back and play the first part of the video it won't, it just jumps back to the 2-10 second jump ahead spot and plays from there. In further investigating it is stripping the audio off correctly and keep all the first 2-10 seconds of the audio with the video clip, but it is not picking up the first 2-10 seconds of the video. When I go into VLC Media Player and try to go back to the beginning I have a frozen image on the screen until I get to the 'predestined' 2-10 second mark, and then the video will play fine. When I watch the original video, it is okay but when I strip it the new video doesn't pick up the beginning of the video. Finally had to go to VLC media player to figure that part out as it was the only one who even let me play the underlying audio, every other media player wanted to jump ahead and skip the entire first 2-10 seconds altogether.

  


  This is happening with numerous different videos and video segments within the same video. Some segments it will strip fine others it won't.

  


  This occurs either way, python or command line. I just checked and the underlying video plays fine in the regular media player, until I strip the video, then it wants to skip the first 10 seconds.

  


  How might I fix this problem ?
