• I am phasing a issue of " ffmpeg attribute 'error'" in my project which is a voice command assistant using GPT 3.5 Turbo and BING API [closed]

  2 mai 2023, par Rudraksh Singh Bhadauria

  I ma working on a pyhton project as want to make a program which can work as fluent as GPT and can also adapt latest news through BING API but after trying a lot I am stuck with a issue where "Error transcribing audio : module 'ffmpeg' has no attribute 'Error'" I have tried installing these ffmpeg files again and again in the way already mentioned in stack overflow but for me its not working.

  


  I have tried using :
installing ffmpeg-pyhton in my terminal and also ffmpeg module and also I have reinstalled the whole files and also have put them in my environment variables.
If anyone could help me to sort this problem out then it will be great help.

  


• 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 ?
