• Python can't access FFmpeg binary in /data/user/0/com.app.name/files/ in Android Studio

  18 octobre 2024, par Dudek 3D

  I'm a beginner in android development (and java). I'm making a hybrid application in java which runs python (using chaquopy).
MainActivity.java runs the python script fine, the only problem is that the yt_dlp library that I've used can't access FFmpeg.
The FFmpeg binary file (for linuxarm64, I don't think that's the problem) is located in the assets folder (src/main/assets), then it's copied to /data/user/0/com.app.name/files :

  


  //FileUtils.java
public class FileUtils {
    public static void copyAsset(Context context, String assetName, String outputPath) {
        AssetManager assetManager = context.getAssets();
        try {
            InputStream in = assetManager.open(assetName);
            File outFile = new File(outputPath);
            OutputStream out = new FileOutputStream(outFile);
            byte[] buffer = new byte[1024];
            int read;
            while ((read = in.read(buffer)) != -1) {
                out.write(buffer, 0, read);
            }
            in.close();
            out.close();

            // Set executable permissions for the binary
            outFile.setExecutable(true);  // Ensure the file is executable
            outFile.setReadable(true);
            outFile.setWritable(true);
            Log.d("FileUtils", "FFmpeg File - Exists: " + outFile.exists() +
                    ", Executable: " + outFile.canExecute());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}


//MainActivity.java
public class MainActivity extends AppCompatActivity {
    private pyRun pyrun;
    private static final int REQUEST_CODE_PERMISSION = 123;
    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.d("YTDownloader", "onCreate: Starting...");
        String ffmpegPath = getFilesDir() + "/ffmpeg";

        // Copy the binary
        FileUtils.copyAsset(this, "ffmpeg", ffmpegPath);

        // Check if file exist and log
        Log.d(TAG, "FFmpeg exists: " + new File(ffmpegPath).exists());
        Log.d(TAG, "PATH: "+ffmpegPath);

        //load python
        //load webview
    }
    //other functions
}


  


  And finally it should be loaded by yt_dlp in python :

  


  import os
import yt_dlp as youtube_dl
ffmpeg_path='/data/user/0/com.dudek3d.ytdownloader/files/ffmpeg'

ydl_opts = {
'ffmpeg_location': ffmpeg_path,
'format': 'bestvideo+bestaudio/best',
'postprocessors': [{
        'key': 'FFmpegVideoConvertor',
        'preferedformat': 'mp4'}],
'noplaylist': True,
'quiet': True,
'merge_output_format': 'mp4',
'outtmpl': filename+'.%(ext)s',
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])


  


  The downloaded file is corrupted because FFmpeg is not found.
I've found out that ffmpeg file cannot be accessed from neither Java nor Python.

  


  I've tried :

  


  1)
Changing the paths to cache : ffmpeg_path='/data/user/0/com.dudek3d.ytdownloader/cache/ffmpeg'
Changing the paths to data : ffmpeg_path='/data/data/com.dudek3d.ytdownloader/files/ffmpeg'
Changing the paths to data cache : ffmpeg_path='/data/data/com.dudek3d.ytdownloader/cache/ffmpeg'

  


  2)
Accessing ffmpeg path from MainActivity.java and got "Permission Denied" Error, so I added

  


  



  


  to AndroidManifest.xml but still the same error occurs.

  


  3)
Using ffmpeg implementations in dependecies in build.gradle (app Module) such as : 'com.arthenica:ffmpeg-kit-full:4.5'
but this won't work because I think that's accessible by java and not python.

  


  4)
I've changed location of ffmpeg to src/main/jniLibs/arc64-v8a :
ffmpegPath = getApplicationInfo().nativeLibraryDir + "/ffmpeg";
passed that to python :

  


  def run(format_choice, listt, ffmpeg_pat, ffprobe_pat):
    global ffmpeg_path, ffprobe_path
    ffmpeg_path, ffprobe_path= ffmpeg_pat, ffprobe_pat


  


  but I got :
WARNING: ffmpeg-location /data/app/~~42sSKOephY26jjdLYW7wmw==/com.dudek3d.ytdownloader-OWqWbazkZobYNlsqTsxfyA==/lib/x86_64/ffmpeg does not exist!

  


  I hope it's clear, thanks in advance.
