• ffmpeg.so in PHP exec converting and no return

  13 juin 2015, par Tom

  I have seen many threads, but none working ones, so this is my issue :

  I have server installed ffmpeg (ffmpeg-php version 0.7.0, PHP Version 5.4.41) Linux CentOS 6 64bit :

  Using PHP :

  exec('/usr/lib64/php/modules/ffmpeg.so -i test.mp4 testdone.avi',$out,$ret);

  or

  exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi',$out,$ret);

  or

  exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi'.' 2>&1',$out,$ret);  

  the ffmpeg is actually found, but always returns : array(0) { } int(11) and with 2>&1 returns array(0) { } int(139) and does not return anything else like testdone.avi in the directory or -version (in the directory). Directories /var/www/html/ are set to 777.

  Thank you, should I hire someone to fix this or am I missing something in PHP.

• ffmpeg - Audio Issues with TS File

  5 décembre 2020, par MeaningOfLife

  I am new to the world of ffmpeg, so I apologize in advance if this is a stupid question or request.

  


  I'm in the process of trying to convert a .ts file to a h264/mp4. I was able to successfully convert the video, however whenever I go to play the output file, the audio is weird. Most of the audio is only coming through the left channel. I noticed that the audio has multiple channels - 6 to be exact. And there are two audio streams as well. I'm assuming that this has something to do with it, but I am not sure what exactly to put in the command line to fix it.

  


  I was hoping there would be a way to copy the video stream from the mp4 I had already made with ffmpeg, and then replace the audio from that mp4 with the audio from the source ts file - preferably mixed down into regular stereo audio. It is quite a big file, so I would like to not have to convert the video stream again if I don't have to.

  


  Here is the media information from the source video.

• Anomalie #2065 : Liste de travaux - page vide

  4 mai 2011, par Teddy Payet

  Le titre de la page (ainsi que dans le menu) est "Liste de travaux". Ça ne serait pas mieux "Liste des travaux" ("des" à la place "de").
