• Android apk file too big when using FFMPeg encoder library

  9 novembre 2022, par Diego Perez

  I'm developing an app which creates x264 videos with the following library :

  



  com.arthenica:mobile-ffmpeg-full:4.2.2.LTS


  



  but the result apk file is too big ( 71mb), so I tried :

  



  com.arthenica:mobile-ffmpeg-min-gpl:4.2.2.LTS


  



  and this way, as the library downloads only a few codecs -included the ones I need- apk size was reduced to 49mb, what is much better, but still looks too big to me, so I'd need to know if any of you know a better way to reduce apk size, because people generally refuse to download such big apps

  



  Regarding the rest of the app (drawables, resources and so) they're well optimized, because if I remove this library and rebuild, the size of the app drops to 10mb

  



  I was reading this question :
FFMPEG Android Library Increase Size

  



  and user S.R suggests to compress all cpu architecture models in one archive file and extract target cpu lib based on cpu model on app's directory and load ffmpeg from there, but I really don't know how to do that.

  



  I'm checking my app's folder structure and noticed there are this next folders regarding ffmpeg lib :

  



  arm64-v8a => ~16mb
armeabi-v7a => ~29mb
x86 => ~17mb
x86_64 => ~21mb


  



  But not sure if I could remove any of them, and as you can see armeabi-v7a is the largest.

  



  

  


• Media type not supported after FFMpeg compression

  9 décembre 2017, par amit srivastava

  I am compressing a video(mp4) in android using FFMpeg it is getting compressed successfully, but when I am trying to open compressed file in mobile device it says "Media type not supported", though I can play that media in my computer’s VLC player.

  My purpose is to compress and post it to server as Multipart but it is also failing because server can’t read media Metadata.

  I am using EpMedia android library to rum FFMpeg command which is :

  String[] command = {"-y", "-i", sourceFile.getAbsolutePath(), "-s", "160x120", "-r", "25", "-vcodec", "mp4", "-b:v", "150k", "-b:a", "48000", "-ac", "2", "-ar", "22050", destFile.getAbsolutePath()};
  
  EpEditor epEditor =  new EpEditor(context);
  
  epEditor.execCmd(cmd, 0, new OnEditorListener(){
  
         @Override
  
         public void onSuccess(){
  
             Log.d("Compress", "Success");}
  
  
  
         @Override
  
         public void onFailure(){
  
             Log.d("Compress", "Failed");
  
         }
  
  
  
         @Override
  
         public void onProgress(float progress){
  
             Log.d("Compress", "Running");
  
         }
  
     });

  I have also tried using SiliCompressor android library but same thing happened Media type not supported resulting issue in uploading to server.

  What can be done in this scenario, even if I upload the media to server what if I want to play that media on mobile device.

• Android Studio FFMPEG "Protocol not found"

  26 novembre 2022, par Whitestripe7773

  I am trying to run ffmpeg with android studio, but when I try the following code it shows this error message :

  


  E/mobile-ffmpeg : content ://media/external/video/media/68 : Protocol not found
E/mobile-ffmpeg : Did you mean file:content ://media/external/video/media/68 ?

  


  This is my code :

  


  inputVideo = "content://media/external/video/media/68"
videoTitle = "abc"
public void method(String inputVideo, String videoTitle) {
        String cmdLine = "-i " + inputVideo + " -vcodec libx265 -crf 28 file:" + videoTitle;
        FFmpeg.execute(cmdLine);
    }


  


  I think that the 'content :' in inputVideo leads to the error but I don't know how I could fix it.
Already tried out the following :

  


  

  • Add 'file :' in front of inputVideo and videoTitle

  


  • Removing 'content ://' from the string leads to not finding the file
