I tried the source code you created. but i get an error

java.lang.IllegalArgumentException: You need to supply a url to a clear MP4 file to download and encrypt, or modify the code to use a local encrypted mp4

Because my in MainActivity.java line 94
new DownloadAndEncryptFileTask(null, mEncryptedFile, encryptionCipher).execute();
in class DownloadAndEncryptFileTask constructor
public DownloadAndEncryptFileTask(String url, File file, Cipher cipher) { if (url == null || url.isEmpty()) { throw new IllegalArgumentException("You need to supply a url to a clear MP4 file to download and encrypt, or modify the code to use a local encrypted mp4"); } mUrl = url; mFile = file; mCipher = cipher; }
Do I have to fill with url strings?

Maaf ini hanya saran saya

After a long time not working on streaming file encryption I finally had an idea and tried to implement it. I tried to find more information about exoplayer and I found the okhttpdatasource library, I think the concept of okhttpdatasource is almost similar to EncryptedFileDataSource that you have created, some equations using inputstream. I tried combining okhttpdatasource with EncryptedFileDataSource, finally successfully playing. But when I ran the audio, I can't move it. I tried to detect errors and try to get a difference. The mInputStream variable in the EncryptedFileDataSource classs I try to get the number of bytes every time the read function reads the result the byte changes but when I mInputStreamdi classs OnlineEncryptedFileDataSource byte it remains 0.
I really don't know what to do for that, and until now I don't have a new idea to solve this problem maybe because I don't know how to work the search bar in exoplayer.
Please help from Mr. Moagrius. A little information might make me have an idea to solve my problem.
Thank you for your attention and assistance.
this sample code https://github.com/rohanisuhadi/DemoStreamingEncryptionExoplayer/blob/master/app/src/main/java/com/example/suhadi/demostreamingencryptionexoplayer/OnlineEncryptedFileDataSource.java

first time download the video file and play perfectly but when I close the app and hit download button it correctly says file already found no need to download again and when I hit play it gives me following error:

Hi
Recently I used EncryptedExoPlayerDemo to play encrypted files it has no problem in playing files with less than 2GB volume but unfortunately, I couldn't play more to 2GB files.
Is there any solution for solving this problem.
Thanks so much.

error :

Source error.
com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor) could read the stream.

Please update to new version of exoplayer, thanks!

When I tried to play an encrypted file using the same codes of your facing this issue.

Hi @moagrius
Is there any possibility to play encrypted video URL on the fly? Encryption follows is AES/CTR/NoPadding
The method mentioned by you in this repo is working fine with local encrypted video if I put the same video from URL to local storage.
The code that I have tried is below, the rest of the code is a copy of DefaultHTTPDataSource in exoplayer package
SecretKeySpec sks = new SecretKeySpec(key, "AES"); Cipher cipher = Cipher.getInstance("AES/CTR/NoPadding"); cipher.init(Cipher.DECRYPT_MODE, sks, ivParameterSpec); InputStream inputStream = connection.getInputStream(); this.inputStream = new StreamingCipherInputStream(inputStream, cipher);

don't know why this is happening.

i am trying to play own encrypted video with specific key..and used same key in your code ..but still facing below error in response..

com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor) could read the stream.

Is there a .apk example available?

Hi, I am using this for encrypting and saving that file locally, afterwards i'm simply playing my encrypted videos from playVideo() method.. and it's working really fine.
But now i want to decrypt and save this video locally how can i achieve that ? Please suggest

Hi Mike ! I was following this ExoPlayer issue https://github.com/google/ExoPlayer/issues/2467
and I found your sample code useful, especially for media seeking.
Could please add some Apache license for it so I can use it with no worries?

can it use the same way on decrypted ? i have tried it,but i fail.

Hi, i tweaked code which is now open video from sdcard and encrypt it and it works perfect for the first time, but for second time when i close and reopen application it gives me following

can you please suggest me something below is my code for EncryptFileTask

public class EncryptFileTask extends AsyncTask<Void, Void, Boolean> {

    private File inputFile;
    private File mFile;
    private Cipher mCipher;

    public EncryptFileTask(File inputFile, File file, Cipher cipher) {

        this.inputFile = inputFile;
        mFile = file;
        mCipher = cipher;
    }

    private boolean downloadAndEncrypt() throws Exception {
        try {
            long startTime = System.currentTimeMillis();
            FileInputStream inputStream = new FileInputStream(inputFile);
            FileOutputStream fileOutputStream = new FileOutputStream(mFile);
            CipherOutputStream cipherOutputStream = new CipherOutputStream(fileOutputStream,
                    mCipher);

            byte buffer[] = new byte[1024 * 1024];
            int bytesRead;
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                cipherOutputStream.write(buffer, 0, bytesRead);
            }

            inputStream.close();
            cipherOutputStream.close();

            float totalTimeInSeconds = (System.currentTimeMillis() - startTime) / 1000f;
            Log.e("Encryption", "Completed for " + inputFile.getName() + " in " + totalTimeInSeconds
                    + " seconds");
            return true;
        } catch (Exception err) {
            err.printStackTrace();
            return false;
        }

//    connection.disconnect();
    }

    @Override
    protected Boolean doInBackground(Void... params) {
        try {
            return downloadAndEncrypt();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return false;
    }

    @Override
    protected void onPostExecute(Boolean aVoid) {
        Log.e(getClass().getCanonicalName(), "Encryption done");
        if (aVoid) {
            inputFile.delete();
        }
    }
}

and following is my method which play video

public void playVideo(View view) {
        mEncryptedFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
                + "/enc_oliver.mp4");
        if (hasFile()) {
            DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
            TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(
                    bandwidthMeter);
            TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
            SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
            mSimpleExoPlayerView.setPlayer(player);
            DataSource.Factory dataSourceFactory = new EncryptedFileDataSourceFactory(mCipher,
                    mSecretKeySpec, mIvParameterSpec, bandwidthMeter);
            ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
            try {
                Uri uri = Uri.fromFile(mEncryptedFile);
                MediaSource videoSource = new ExtractorMediaSource(uri, dataSourceFactory,
                        extractorsFactory, null, null);
                player.prepare(videoSource);
                player.setPlayWhenReady(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else {
            Log.e("ERROR!!", "File not found");
        }
    }

Just wanted to say thanks for sharing your solution! Got stuck just like you with the regular CipherInputStream (that worked like a charm with an HTTP server in the middle, but not with Exo directly), and solving this would have taken me ages if I hadn't stumbled over your contribution 😄
