  22 mars 2020, par Jehonadab Okpukoro

  I’m trying to crop a video with Flutter_ffmpeg package using this -i $inputPath -filter:v "crop=80:60:200:100" -c $outputPath, but I’m having this error message

• Nodejs couldn't find the ffmpeg module for some reason

  29 décembre 2020, par Chawchawchaw

  I need to display the live streaming vidoe(rtsp) on a website(http, vue framework) with nodejs and vue framework.

  


  I've looked it up a lot and got the basic logic of what they are and how it works.
So I'm planning on to convert rtsp to hls with nodejs using socket.io and display it on a web.(let me know if there's more efficient way way to do it)

  


  The thing is, for some reason, when I try to develop it in my backend(nodejs), node just keep sends me an error that FFMpeg module wasn't found. It's been over a week.. please help.

  


  Btw, all works with ffmpeg cmd(window powerShell).

  


  How I set up(ffmpeg) :

  


  


  1. downloaded ffmpeg from https://ffmpeg.org/

     


  


  2. added to system path : C :\Users\Marie\Desktop\ffmpeg-4.3.1-2020-11-19-full_build\bin

     


  


  3. tested with window powerShell and converted rstp to m3u8 :

     


     ffmpeg -i 'rtsp ://ip.ip.ip/media/video1' -hls_time 3 -hls_wrap 10 'C :\Users\Marie\Desktop\tmp\hls/streaming.m3u8'

     


  


  


  below is a screen shot of no. 3 result


  


  ---

  


  how I set up(nodejs)

  


  

  1. npm i ffmpeg fluent-ffmpeg rtsp-ffmpeg

  


  2. I've just copied and pasted the example working code and changed rtsp link to mine. e.g : (https://www.npmjs.com/package/rtsp-ffmpeg)

  


  


  => didn't work out, error says can't find ffmpeg module

  


  

  3. set up path manually e.g.) ffmpeg.setFfmpegPath(path)

  


  


  => didn't work out. error says can't find ffmpeg module

  


  ...
I've seriously tried almost everything like delete, re-install ffmpeg, changed path, added path manyally, .. Please help....

  I'm trying to convert video files to DASH format. All videos work great except MOV videos.

  


  I'm using the following command :

Stream #0:3 -> #0:3 (copy)


  


  I guess the problem is that the file contains two not audio/video streams :
I can not find a way to exclude or ignore or copy without processing those last two streams (#2 and #3).
