• Loading ffmpeg-php module fails

  21 août 2013, par i.h4d35

  I've been trying this for a couple of days now. I am trying to install ffmpeg-php on my CentOS server.

  • OS : CentOS 6
  • PHP : 5.5
  • ffmpeg : 1.2.1
  • ffmpeg-php : 0.6.0

  The ffmpeg installation went on without a hitch and I am able to convert files back and forth via the CLI.

  While installing ffmpeg-php, I encountered errors while making (after configuring) due to time.h references which was corrected by renaming the files creating with an extension .loT to .lo (as rightly pointed out here)

  Once this was done, the make process went on smoothly and the make install went through without a hitch. However, after specifying the extension=ffmpeg.so in the php.ini file and after restarting Apache, the module doesn't load or show up in phpinfo().

  The Apache error log shows only "PHP Warning : PHP Startup : Invalid library (maybe not a PHP library) 'ffmpeg.so' in Unknown on line 0" and nothing else.

  make test also shows the same error and FAILS the associated tests. I've checked here which wasn't very helpful. Also, I read somewhere that it may be the issue with permissions but the permissions for the ffmpeg.so file is 755.

  Any help is appreciated.

  Thanks in advance.

• FFmpeg add a text to last image only

  29 mai 2018, par BentCoder

  I managed to create a video from set of non-sequential images and attached an audio to it. Also I added a "Copyright" text on top right hand corner so that the text appears throughout the video. However, I would like that text to appear only on the last image. How should I change my code below to address this ?

  ffmpeg \
  
  -thread_queue_size 512 -f image2 -pattern_type glob -framerate 1/3 \
  
  -i '*.jpg' \
  
  -i 'audio.mp3' \
  
  -c:a aac -c:v libx264 \
  
  -vf scale=640:480, format=yuv420p, drawtext="text='Copyright':fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5:x=w-tw-5:y=5" \
  
  -preset medium \
  
  video.mp4
