• Checking for files in a directory with bash script ? what is wrong with this code ?

  4 décembre 2016, par A Sahra

  I have written this code to check for video files in a directory and convert them with ffmpeg.
  while running this script i get out put as "[ERROR] File Not Found" which i have it in else block.what is wrong with the script that i don’t get the files.

  #!/bin/bash
  
  # set PATH to check existance of video file in this directory
  
  checkfiles='/home/webuser/public_html/shareportal/convertedUp_videos/'
  
  #format of output video file
  
  webm='webm'
  
  for f in checkfiles
  
  do
  
  fullfilename="$f"
  
  filenamewithpath=$(basename "$fullfilename")
  
  filewithoutext="${filename%.*}"
  
  fileextention="${filename##*.}"
  
  changeextension=mv --"$f" "${f%.$fileextention}.$webm"
  
  outputfilename="/home/webuser/public_html/shareportal/converted_videos/$changeextension"
  
  echo "File FUll NAME : $fullfilename"
  
  echo "File name with full path : $filenamewithpath"
  
  echo "File name without extention : $filewithoutext"
  
  echo "File extention : $fileextention"
  
  echo '1 File Converted'
  
  if (ffmpeg -i "$f" "$outputfilename")
  
  then
  
  confullfilename="$outputfilename"
  
  confilenamewithpath=$(basename "$confullfilename")
  
  confilewithoutext="${filename%.*}"
  
  confileextention="${filename##*.}"
  
  echo "File FUll NAME : $confullfilename"
  
  echo "File name with full path : $confilenamewithpath"
  
  echo "File name without extention : $confilewithoutext"
  
  echo "File extention : $confileextention"
  
  echo '1 File Converted'
  
  else
  
  echo "Could Not Convert File"
  
  fi
  
  #get Image of video file on provided time stamp
  
  image_path='/home/webuser/public_html/shareportal/video_images/$filewithoutext.png'
  
  if (ffmpeg -ss 00:00:03 -i "$f" -vframes:v 1 "$image_path")
  
  then
  
  echo "Image Extracted"
  
  else
  
  echo "Could not Extract Image"
  
  fi
  
  done
  
  rm -r f

• Video with wrong orientation when exporting with Ffmpeg on Android

  12 décembre 2016, par Thibaut Brnl

  I’m developing an app in which I use Ffmpeg to export a video with some drawings on it. When I use it with a landscape video, the export is OK but when I use it with a portrait video, the video is rotated to landscape orientation...
  The ffmpeg command I use is

  new String[]{
  
    f.getAbsolutePath(), 
  
    "-i", inputVideo,
  
    "-i", bitmap,
  
    "-preset", "ultrafast",
  
    "-filter_complex", "overlay=0:0",
  
    "-b:v", "3000k",
  
    "-strict", "-2",
  
    "-fs", "20M",
  
    outputVideo
  
  };

  . When I remove the filter_complex overlay=0:0 instruction, the video keeps its correct orientation. The ffmpeg version is 2.4.2.
  Does someone has an idea about how to correct this problem ?
