How to convert video to base64 data

I have an app that take video from camera or gallery and convert it into base64 data and that data send to server but the problem is whenever I convert base64 data it will be not correct data in videodata variable. for this I used below code : 

FileInputStream objFileIS = null;
try
{
    System.out.println("file = >>>> <<<<<" + selectedImagePath);
    objFileIS = new FileInputStream(selectedImagePath);
} 
catch (FileNotFoundException e) 
{
    e.printStackTrace();
}
ByteArrayOutputStream objByteArrayOS = new ByteArrayOutputStream();
byte[] byteBufferString = new byte[1024];
try
{
    for (int readNum; (readNum = objFileIS.read(byteBufferString)) != -1;) 
    {
        objByteArrayOS.write(byteBufferString, 0, readNum);
        System.out.println("read " + readNum + " bytes,");
    }
} 
catch (IOException e)
{
    e.printStackTrace();
}                    

videodata = Base64.encodeToString(byteBufferString, Base64.DEFAULT);
Log.d("VideoData**>  " , videodata);

Please make it correct...

Try this code, paste it into a ".html" and see if you like what it puts in the console.log:

<input type="file" accept="video/*" oninput="uploadFile(this)" />

function uploadFile(event) {
    var file = event.files[0];
    var reader = new FileReader();
    reader.onload = (event) => {
        var media = event.target.result;

        console.log(media);
    };
    reader.readAsDataURL(file);
}

I solve it like this:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Log.d("Imagen este ", String.valueOf(data));
        if(data!=null) {
            switch (requestCode) {
case SELECT_VIDEO:
                    Uri selectedVideoUri = data.getData();
                    String[] projection = {MediaStore.Video.Media.DATA, MediaStore.Video.Media.SIZE, MediaStore.Video.Media.DURATION};
                    Cursor cursor = managedQuery(selectedVideoUri, projection, null, null, null);

                    cursor.moveToFirst();
                    String filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA));
                    Log.d("File Name:",filePath);

                    Bitmap thumb = ThumbnailUtils.createVideoThumbnail(filePath, MediaStore.Video.Thumbnails.MINI_KIND);
                    // Setting the thumbnail of the video in to the image view
                    msImage.setImageBitmap(thumb);
                    InputStream inputStream = null;
// Converting the video in to the bytes
                    try
                    {
                        inputStream = getContentResolver().openInputStream(selectedVideoUri);
                    }
                    catch (FileNotFoundException e)
                    {
                        e.printStackTrace();
                    }
                    int bufferSize = 1024;
                    byte[] buffer = new byte[bufferSize];
                    byteBuffer = new ByteArrayOutputStream();
                    int len = 0;
                    try
                    {
                        while ((len = inputStream.read(buffer)) != -1)
                        {
                            byteBuffer.write(buffer, 0, len);
                        }
                    }
                    catch (IOException e)
                    {
                        e.printStackTrace();
                    }
                    System.out.println("converted!");

                    String videoData="";
                    //Converting bytes into base64
                    videoData = Base64.encodeToString(byteBuffer.toByteArray(), Base64.DEFAULT);
                    Log.d("VideoData**>  " , videoData);

                    String sinSaltoFinal2 = videoData.trim();
                    String sinsinSalto2 = sinSaltoFinal2.replaceAll("\n", "");
                    Log.d("VideoData**>  " , sinsinSalto2);

                    baseVideo = sinsinSalto2;

videoData has the base64 of the video.. I hope you serve, I worked perfect

When you encode the byteBufferString, you are encoding only the last chunk of data read. You should encode the whole contents of the ByteArrayOutputStream. You can do this with the following code:

videodata = Base64.encodeToString(objByteArrayOS.toByteArray(), Base64.DEFAULT);

However, there is a chance that this may throw an OutOfMemoryError if the video size is big.
