• 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 ?

• How to do low-latency streaming on FFMPEG

  1er avril, par Wewd

  I'm attempting to make video streaming with latency as low as possible at 50ms or lower if possible, assuming that it's streaming over LAN.

  


  The latency is like 200-400ms with the config. I'm not sure what's the problem is.

  


  ffmpeg -init_hw_device d3d11va \
-filter_complex "ddagrab=0:output_fmt=auto:framerate=60" \
-c:v av1_amf -usage ultralowlatency -rc 1 -async_depth 1 -g 60 -fps_mode vfr \
-fflags nobuffer -flags low_delay -strict experimental \
-sdp_file stream.sdp -f rtp rtp://225.0.0.1:55555


  


  stream.sdp

  


  v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 225.0.0.1
t=0 0
a=tool:libavformat 61.9.107
m=video 55555 RTP/AVP 96
a=rtpmap:96 AV1/90000
a=fmtp:96 profile=0;level-idx=14;tier=0


  


  Decided to keep ffplay simple since I tried many options without any tangible benefit.

  


  Run it on different PC

  


  ffplay -hide_banner -protocol_whitelist "file,udp,rtp" -i stream.sdp
