• 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.

• 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.

• Configure script for ffmpeg does not find sdl2

  3 avril 2018, par Peter

  Environment :

   Ubuntu 16.04
  
   ffmpeg source code version 3.4.2

  SDL2 installed

  $ pkg-config --exists --print-errors sdl2
  
  $ sdl2-config --cflags
  
  -I/usr/include/SDL2 -D_REENTRANT
  
  $ sdl2-config --libs
  
  -L/usr/lib/x86_64-linux-gnu -lSDL2
  
  $ sdl2-config --version
  
  2.0.4

  Here is part of my configuration shell script :

  PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$TARGET_DIR/lib/pkgconfig" ./configure \
  
  --prefix="$TARGET_DIR" \
  
  --pkg-config-flags="--static" \
  
  --enable-sdl2 \

  When I run the script, the error I get is "sdl2 requested but not found."

  What is it that I am missing ? Regards.
