  i am uploading a video by this code and gets error when uploaded fileseze is more then 20 or 30 mb the error says undefined $profileimage99 (i am uploading the file by ajax)

  i want the page to convert the file to such formats so that all the major browser supports us and the conversation time is also not very much as it takes a considerable time to just do the following task
  the main time taken by the page is by the ffmpeg code

  also please tell me is it good to use exec code in php ????

  Things that i want

  1.convert the video to flv,swf (other format if any which is supported by browesers )
  2.reduce the conversation time
  3.is it good to use exec here in php code
  4. take the frame (convert a jpg file out of the video) after half time of the video (like if the video is of 4 hrs then get the frame which is just after 2hrs)

  Please send me any link or related code or explain me something about ffmpeg

• How to reduce video size using node ffmpeg

  11 octobre 2022, par Chanaka De Silva

  I'm using following npm package in NodeJS application.
What I need to do is reduce the size of videos.
My videos are in mp4 format.
Is there any way to reduce size of those videos using node-ffmpeg ?
https://www.npmjs.com/package/ffmpeg

  



  There are not good answers or samples. I followed this code some steps and idea, but no good. fluent ffmpeg size output option not working

  



  In normal ffmpeg, we can do like this.

  



  ffmpeg -i <inputfilename> -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy <outputfilename>&#xA;</outputfilename></inputfilename>

  



  How can we do the same in NodeJS ?

  



  Please help me on this.
any sample code or idea is welcome.
