• "ffmpeg has text relocations" error in Android

  5 janvier 2015, par djzmo

  I’m building an Android video-sending application. I need the video to be compressed before being uploaded. In this case, I chose to use this Android wrapper of FFmpeg : https://github.com/hiteshsondhi88/ffmpeg-android-java

  FFmpeg error: WARNING: linker: /data/data/com.mycompany.myapplication/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

  Everything seemed fine when I compress small files (below 20 seconds), but when I tried to compress larger files, I seldom get the above error in the middle of the compression process, and the process was also terminated immediately. I need the application to be able to compress one minute video to about 20-35 MB.

  Here is the FFmpeg command I used :

  ffmpeg -y -i -codec:v libx264 -profile:v baseline -level 3.0 -b:v 2500k -minrate 2500k -maxrate 2500k -bufsize 1835k -pix_fmt yuv420p -preset ultrafast -crf 28 -codec:a copy

  Any idea on what went wrong ?
  Any kind of help would be very appreciated.

• Ffmpeg is not always converting correctly

  11 juin 2016, par Lewis Day

  I’m having some problems when I’m using this command to convert video formats It sometimes works and sometimes it doesn’t. For .avi files it works for .3gpp only converts audio and for .flv it completely doesn’t work is there something that I’m doing wrong basically the $newfilename will only ever be video formats and the output format will always be a .mp4 Thankyou for any help

  ffmpeg -i /path/' . $newfilename . ' -vcodec copy -acodec copy /path/' . $rand . '.mp4'

  When I try and convert a .flv to .mp4 this is what is produces
