  avcodec/vp56 : Implement very basic error concealment
  This should fix the fate failure due to a truncated last frame.
  
  Alternatively the frame could be dropped.

• My Android app release is too big than expected

  11 avril 2020, par Abhi Jith

  I have created a simple android app to download the whatsapp status

  



  I have completed all the functionalities.then the app size is less than 5MB


  



  After that i added a third party plugin to add my app name to the downloaded video files as watermark

  



  i used ffmpeg to add water mark in the video


  



  But after that my app release size reached around 20MB.

  



  I used minifyEnabled true to shrink the code.but doesn't worked


  



  How to reduce my release size

  


• expected end of line but found unknown token

  17 juin 2017, par Denzil Williams

  Ok so after days of searching, here I am. I am new to ffmpeg, applescript, and terminal.

  I want to use ffmpeg to batch convert a group of selected files in any folder. I was successful in doing this by opening the terminal at the folder location and using this code :

  for f in *.flv; do ffmpeg -i "$f" -acodec libmp3lame -b:a 256k "${f%.flv}.mp3" && rm "$f"; done

  which finds all flv files, and converts it to 256 bit rate mp3, then deletes the original files.

  Now I want it to be more automated, so I looked into creating a service. I tried running an apple script through automator, which I want it to open the terminal at the folder location the file then run the code to convert the files. Here’s the code I attempted :

  tell application "Finder" to set currentFolder to target of front Finder window as text
  
  set theWin to currentFolder's POSIX path
  
  
  
  tell application "Terminal"
  
      if not (exists window 1) then reopen
  
      activate
  
      do script "cd " & quoted form of theWin & ";clear" in window 1
  
      tell application "Terminal"
  
          do script "for f in *.flv; do ffmpeg -i "$f" -acodec libmp3lame -b:a 256k "${f%.flv}.mp3" && rm "$f"; done"
  
      end tell
  
  end tell

  The first part of code opens up terminal at the folder location just fine. But when I add the part with the ffmpeg code it crashes. The error is apparently with the "$", those are what light up as the error, the error message says "Expected end of line, but found unknown token". Looking for some assistance please. I need the "$" because those are what make the loop work for renaming the files and such.
