• Run script after FFMPEG background task completes (via PHP)

  9 novembre 2018, par Utkanos

  I have a PHP script which triggers an FFMPEG file conversion via shell_exec().

  shell_exec('ffmpeg -i file.webm -c:v libx264 -c:a aac -strict -2 file.mp4 >/dev/null 2>/dev/null &');

  This happens in the background (hence &), i.e. the script completes before conversion has finished.

  Is there a way to call and execute a PHP script (to update a DB flag) once the conversion is complete ?

  I’ve done plenty of Googling but my knowledge of server commands just isn’t up to understanding what I’m reading (e.g. this answer). The best I could manage was to redirect stdout to a file via

  shell_exec('ffmpeg -i file.webm -c:v libx264 -c:a aac -strict -2 file.mp4 > MYFILE.txt 2>/dev/null &');

  ...but obviously that just creates and writes to a file, it doesn’t call and execute it via PHP.

• Find exe files in batch script

  20 septembre 2017, par D.Spam

  Ok so I have a batch script that looks something like this

  :Input
  
  ECHO.
  
  SET url=
  
  ECHO Enter URL
  
  SET /P url=
  
  IF "%url%" EQU "" GOTO End
  
  IF "%url: =%" NEQ "%url%" GOTO Input
  
  ECHO Enter start time (in seconds, or in hh:mm:ss form):
  
  SET /P start=
  
  ECHO Enter duration (in seconds, or in hh:mm:ss form):
  
  SET /P dur=
  
  ECHO.
  
  FOR /F "delims==" %%A IN ('youtube-dl.exe --no-warnings --get-filename "%url%"') DO SET filename=%%A
  
  FOR /F %%B IN ('youtube-dl.exe -g "%url%"') DO (
  
  ffmpeg.exe -hide_banner -ss "%start%" -i "%%B" -c copy -t "%dur%" -bsf:a aac_adtstoasc video.mp4
  
  )
  
  
  
  :End

  The script works flawlessly but my only problem is the script only works when the batch file is inside the folder with all the executables (ffmpeg.exe, youtube-dl.exe). I would like the scripts to run outside the folder

  The folder in which the executables are :
  \Clips\ffmpeg\bin

  The folder I would like to store/run the batch files from is Clips.

  Another tricky problem is that the Clips folder will be shared with other users so I dont want to specify a directory like G :\Desktop\Clips as it will not work for them.

• FFMPEG & Centos7 Script

  5 octobre 2017, par Tony

  Looking to install FFMPEG on Centos7 - there appears to be an official compilation guide here.

  BUT I find it hard to belive that someone hasn’t already done all the work to make this into a nice install script ? :) ?

  If not I’ll proceed and make one but rather not if I don’t have too.
