截屏

自2017-9-20日起，更新demo后将支持预览截屏功能 需要通过ScreenShotListener获得requestScreenShot返回的Bitmap图像，可以使用如下方法将bitmap保存到sdcard：

mStreamer.requestScreenShot(new IStreamer.ScreenShotListener() {
            @Override
            public void onBitmapAvailable(Bitmap bitmap) {
                BufferedOutputStream bos = null;
                try {
                    Date date = new Date();
                    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy_MM_dd_HH_mm_ss");
                    final String fileName = "/sdcard/screenshot" + dateFormat.format(date) + ".jpg";

                    bos = new BufferedOutputStream(new FileOutputStream(fileName));

                    if (bitmap != null) {
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bos);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                Toast.makeText(StreamActivity.this, "保存截图到" + fileName, Toast.LENGTH_SHORT).show();
                            }
                        });
                    }
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } finally {
                    if (bos != null)
                        try {
                            bos.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                }
            }
        });
