  These are the logs, ffmpeg pushes the stream in a different folder when tried manually.

  


  

  • I tried changing the location of my file outside of oneDrive to avoid any permission conflicts.

  


  • Manually checked if FFmpeg is correct with this command : C:\ffmpeg\bin\ffmpeg.exe -i rtmp://localhost/live/test -c:v copy -c:a aac -f hls -hls_time 2 -hls_list_size 5 -hls_flags delete_segments output/index.m3u8

  


  • Downgraded NMS to a stable version.

  


  


• How to dump ALL metadata from a media file, including cover image title ? [closed]

  9 avril, par Unideal

  I have an MP3 song :

  


  # ffprobe -hide_banner -i filename.mp3
Input #0, mp3, from 'filename.mp3':
  Metadata:
    composer        : Music Author
    title           : Song Name
    artist          : Singer
    encoder         : Lavf61.7.100
    genre           : Rock
    date            : 2025
  Duration: 00:03:14.04, start: 0.023021, bitrate: 208 kb/s
  Stream #0:0: Audio: mp3 (mp3float), 48000 Hz, stereo, fltp, 192 kb/s
      Metadata:
        encoder         : Lavc61.19
  Stream #0:1: Video: png, rgb24(pc, gbr/unknown/unknown), 600x600 [SAR 1:1 DAR 1:1], 90k tbr, 90k tbn (attached pic)
      Metadata:
        title           : Cover
        comment         : Cover (front)


  


  The task is to save its metadata to a text file and restore from that file later. Both goals should be accomplished with ffmpeg.

  


  The simpliest method is to run :

  


  # ffmpeg -i filename.mp3 -f ffmetadata metadata.txt


  


  After that, metadata.txt contains :

  


  ;FFMETADATA1
composer=Music Author
title=Song Name
artist=Singer
date=2025
genre=Rock
encoder=Lavf61.7.100


  


  I got global metadata only, but stream-specific info (cover image title and comment in my case) are missing.

  


  Google suggested a more complex form of the command above to extract all metadata fields without any exclusions :

  


  # ffmpeg -y -i filename.mp3 -c copy -map_metadata 0 -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a -f ffmetadata metadata.txt


  


  But the output is exactly the same :

  


  ;FFMETADATA1
composer=Music Author
title=Song Name
artist=Singer
date=2025
genre=Rock
encoder=Lavf61.7.100


  


  Again, no info about the attached image.

  


  Please explain what am I doing wrong.

  


• How can I crop and encode a video using flutter natively, now that flutter_ffmpeg is discontinued with no alternatives ? [closed]

  13 mars, par Rageh Azzazy

  As of January 6, 2025, FFmpegKit is officially retired (Taner's article).

  


  This also affects the flutter_ffmpeg and ffmpeg_kit_flutter packages.

  


  Most packages for executing video editing commands were built depending on them and so won't work after April 1, 2025 as mentioned in the package documentation and Taner's article. Some packages that depend on flutter_ffmpeg or ffmpeg_kit_flutter are :

  


  

  • video_trimmer

  


  • zero_video_trimmer

  


  • flutter_video_trimmer

  


  • video_trim

  


  • bemeli_compress

  


  • video_trimmer_pro

  


  • ... others

  


  


  Editing video using video_editor or video_editor_2 or video_editor_pits has become a problem.

  


  I believe downloading the binaries and doing the whole thing locally is not just tedious but illegal as well.

  


  I broke down exactly what I need to edit videos in my flutter app and I found those package but have not yet tested them.

  


  


  • ✅ Trimming : flutter_native_video_trimmer

    


  


  • ✅ Compression : video_compress or video_compress_plus

    


  


  • ✅ Muting : video_compress handles this

    


  


  • ❌ Encoding : Not sure, I just need a simple MP4 video files

    


  


  • ❌ Cropping : I can't find a solution for video cropping

    


  


  


  I don't need to rotate, reverse or do any fancy stuff to the videos, just those five functions.

  


  Now the only way forward is to find a simple video cropping function and an encoder that work on flutter IOS & Android

  


  My question is not looking for external library recommendations but :

  


  Do you have any ideas how to crop a video in flutter natively ?
