  I want to merge two videos splitted at the mid screen and sound from first video as like duet/Remix of instagram reels and for merging two video i used ffmpeg-kit-react-native-5.1.0 and now i using the command
const command = `-y -i ${video.path} -i ${videoPlayerRef.current.props.source.uri} -filter_complex hstack ${outputFileName}`;
This will sometime produce video output but this file not supported by any media not even shared by any application, But now for that command giving the error

  


   LOG  [mp4 @ 0xb40000712234c100] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or setting vsync/fps_mode to vfr

 LOG  Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
 LOG  Conversion failed!```
i changed the command to 


  


  const newcomman = -i ${video.path} -i ${videoPlayerRef.current.props.source.uri} -filter_complex "[0:v]scale=iw/2:ih[v0];[1:v]scale=iw/2:ih[v1];[v0][v1]hstack" -r 24 -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 192k -time_base 1/65535 ${outputFileName}

  


  it says 


  


  Unrecognized option 'preset'.
LOG Error splitting the argument list :
and removing of preset it says unrecognized option 'crf' please help me what should be the command that will merge two videos in splitted screen manner  and can support every where byexecuteAsyncofffmpegkit``` , Please help ...

  


• ffmpeg exited with code 1 : Error configuring complex filters

  21 décembre 2015, par rycornell

  I am using the fluent-ffmpeg node package to merge videos. I am following the documentation exactly but I get the following error : Error: ffmpeg exited with code 1: Error configuring complex filters. Here is the code :

  ffmpeg('/videos/test/part1.mov')
  
    .input('/videos/test/part2.mov')
  
    .on('error', function(err) {
  
      console.log('An error occurred: ' + err.message);
  
    })
  
    .on('end', function() {
  
      console.log('Merging finished !');
  
    })
  
    .mergeToFile('videos/test/final.mp4', 'videos/test/tempDir');

  and here is the error output (I logged the command generated by fluent-ffmpeg to the console) :

  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-formats' ] { captureStdout: true }
  
  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-encoders' ] { captureStdout: true }

    'videos/test/final.mp4' ] { niceness: 0 }

  I’m able to run ffmpeg on my machine for other tasks and it works fine. I’m not sure what the ’-filter_complex’ flag is supposed to do. I am using fluent-ffmpeg version 2.0.1 and ffmpeg windows static build git-9d1fb9e (2015-12-17).

• FFmpeg : How to convert vertical/horizontal video (any size) with black sides, to 1080x1350 vertical video with blurred background sides/bottom-top

  12 octobre 2023, par devweb

  i've been trying to make a ffmpeg 'filter_complex' code to make what i need but i can't, i've used some codes here on stack but non works for what i need, each is like for a different size/dimension.
I'm trying to make videos like Instagram posts (tallest allowed) : 1080 x 1350

  


  Bassically, horizontal videos with blurred sides or bottom-top.

  


  Any help will be awesome, thanks !

  


  This is the principal which i tried

  


  Something like this :

  


  Example 1
Example 2

  


  Here some codes i tried to worked with and changing stuff :
filter_complex='[0:v]scale=1080*2:1350*2,boxblur=luma_radius=min(h\\,w)/20:luma_power=1:chroma_radius=min(cw\\,ch)/20:chroma_power=1[bg];[0:v]scale=-1:1080[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2,crop=w=1080:h=1350'

  


  filter_complex='[0:v]scale=ih*5/4:-1,crop=h=iw*4/5,gblur=sigma=20[blurred];[blurred][0:v]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2'

  


  filter_complex='[0:v]scale=1080:1350,setsar=1,gblur=sigma=20[blurred];[blurred][0:v]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2'
