yt-dlp and youtube-dl command in Android Studio(Java code)

I am trying to use yt-dlp command in my java code to extract audio from youtube videos. Basically, I am trying to develop one audio playing application(for better understanding on working with API) where I am using Youtube API. I search any music in my app and it will show youtube video in listview. At this time, audio should extracted from youtube vidoes as I am passing my command in updateListView method. It should return URL(storing in model) which will be used in other class files to play mp3 files. I am trying this thing for more than 1 week now. I tried several ways to do this thing but everytime I got only one same error which image I attached.

 private String getAudioUrl(String videoId)
    {
        File cacheDir = getCacheDir();
        File audioDir = new File(cacheDir, "audio");
        if (!audioDir.exists())
        {
            audioDir.mkdirs(); // Create the directory if it doesn't exist
        }
        try {
            ProcessBuilder processBuilder = new ProcessBuilder(
                    "~/.yt-dlp",
                    "-x",
                    "--audio-format", "mp3",
                    "-P", audioDir.getAbsolutePath() + "/%(title)s.%(ext)s",
                    "https://www.youtube.com/watch?v=" + videoId
            );
            Process process = processBuilder.start();
            BufferedReader read = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String audioUrl = read.readLine();
            read.close();
            Toast.makeText(MainActivity.this, "Playing!!!", Toast.LENGTH_SHORT).show();
            return audioUrl;
        } catch (IOException e)
        {
            e.printStackTrace();
            Toast.makeText(MainActivity.this, "Sorry, Error in playing audio!!!", Toast.LENGTH_SHORT).show();
        }
        return null;
    }

I am trying to call this method in below mentioned method.

 private void updateSearchResultsList(List<SearchResult> results)
    {
        searchResults.clear();
        for (SearchResult result : results)
        {
            String videoTitle = result.getSnippet().getTitle();
            String videoImageUrl = result.getSnippet().getThumbnails().getDefault().getUrl();
            selectedVideoId = result.getId().getVideoId();

            //for testing
            // Log.d("Video ID", "Video ID: " + videoId);

            String audioUrl = getAudioUrl(selectedVideoId);
            YoutubeModel youtubeModel = new YoutubeModel(videoTitle, videoImageUrl, audioUrl);
            searchResults.add(youtubeModel);
        }
        adapter.notifyDataSetChanged();
    }//end of method

So far I tried so many methods those I mentioned below:

  1. Installed yt-dlp with pip and wihtout pip.(same for youtube-dl)
  2. Set path of yt-dlp in environment variables. I tried both path, default python path and by making new folder, put file(yt-dlp.exe) in that folder and then set the path.
  3. I tried to find which path my code navigating and somehow got the path which is "data/user/0/com.example.audio_player/files" . I copied my yt-dlp.exe file here as well but still same error.
  4. Manually set the file in assests folder in android studio and used that path but still no output.
  5. I used both ways to call command -> "~/.yt-dlp" and "yt-dlp".
  6. Somehow I got new error when I used copying file from assets folder to internal directory(which is data/user/0/com.example.audio_player/files) logic, that time I got new error and that says "Permission Denied". I tried to give permission by coding and from manifest as well but still permission denied error I got. I put INTERNET, READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE permissions as well as some new permissions such READ_MEDIA_IMAGES, etc... still no response.
  7. After searhing on we, I found two repo of yt-dlp java and yt-dlp android. I used both repo but it still now working. Here are those repositories: https://github.com/sapher/youtubedl-java and
    https://github.com/yausername/youtubedl-android.

What more I can try to extract audio from youtube video using yt-dlp command or Is there any other way to do this???

Solution

  • After surfing the internet for so many days, I finally found out the solution to do this feature.Well, you can't directly add command code in your android studio java code, as of my research. It will keep throwing an error that yt_dlp: No such or directory as code can't find the path of yt_dlp even though if you add this .exe file of yt_dlp in your assest folder. The simple solution is, as yt_dlp is python module, so we can integrate our python code into our android studio which is allowed to do so, we can get the same result as we got from command line. For that we need to add python library in android studio which is you can get it from here. You can get that python code as well from my repository here.It is located under python folder. This code will return you audio-extracted url which can be used further to play audio file. Hardwork Pays!!!Keep Coding!
