• PHP ffmpeg conversion error

  6 mars 2016, par Enn Fenn

  I tried to convert some videos with ffmpeg and PHP.

  When I execute the following command in PHP exec()

  /usr/local/bin/ffmpeg -i /home/test/public_html/test.m4v -vcodec libx264 -acodec libmp3lame -r 30 -s 640x480 -b 100k /home/test/public_html/output_640x480_test.m4v

  Output :

  The same conversion is working fine in another server. But not in our current server. What should I do to get rid of this error ?

• correctly escaping text in drawtext filter

  6 novembre 2013, par mente

  According to documentation %{}:, should be escaped with slash. But when I escape % the text is not added. There's error message saying Stray % near ')'. But what does it mean and how I can fix it ? Command and output :
