  ffmpeg_filter : do not pick evil path for trim filters

• iOS header search path

  25 mai 2016, par AlecGamble

  So I’m pretty new to iOS development and I’m a little confused by the header search paths. Here are the ones it’s already including :

  

  I presume some (if not all) of these are present because it’s a cordova project.

  In my file structure I’ve added a folder with the FFmpeg libraries (the FFmpeg folder is on the same level as classes within the app directory). I presume I want to include everything in the lib subfolder (they’re all .a files) so my file structure is :

  App Folder (Same level as the .xcodeproj file) > FFmpeg > FFmpeg-iOS > lib > .a files.

  Could somebody suggest to me what linker I should use or how I somewhere I can look to find out ?

  Thanks.

  I’m trying things like :

  $(PROJECT_DIR)/AppFolder/FFmpeg/FFmpeg-iOS/include

  and

  $(SRCROOT)/AppFolder/FFmpeg/FFmpeg-iOS/include

  and then I feel like I should be able to import it as :

  #import <libavcodec></libavcodec>avcodec.h>

  but it’s just not finding it, I’ve tweaked the path a lot.

• Shell script works fine from shell but doesn’t work as expected when executed via PHP “shell_exec” code

  9 décembre 2019, par Eric Feillant

  This record.sh script shell is here and works fine on command line to record an MP4 file from a local flv live stream :

  DATE=`date +"%d-%m-%Y-%T"`
  
  if [ -s NAMESTREAM ]
  
  then
  
  cat config.php | dos2unix | grep auth | grep username | \
  
  awk -F ' ' '{print $3}' | sed "s/'//g" | sed "s/;//g" | while read VAR
  
  do echo $VAR > RECSTREAM
  
  echo "Starting recording ..."
  
  ffmpeg -i "rtmp://localhost/hls/$VAR" -crf 19 videos/"$VAR"_"$DATE".mp4
  
  done
  
  else
  
  echo "Streaming is not started, please start it before"
  
  fi

  I send a shell_exec to call the last shell script in a php script like this :

  $old_path = getcwd();
  
  chdir('/usr/local/nginx/html/mydir');
  
  $output = shell_exec('nohup ./record.sh >/dev/null 2>/dev/null &');
  
  chdir($old_path);

  The MP4 video files are generated but unreadable with VLC, etc… It seems that the problem is due to my PHP script but I am not able to know why.

  When executing from the shell command line : PHP myphpscript.php works fine, MP4 video files are OK. But from the PHP web page, the MP4 video files are corrupted.

  Any ideas ? Any param to test in FFmpeg to have a good mp4 video file ?
