这篇文章主要 A 为大家详细介绍了 Android 视频处理之动态时间水印效果, 具有一定的参考价值,感兴趣的小伙伴们可以参考一下
Android 是一种基于 Linux 的自由及开放源代码的操作系统,主要使用于移动设备,如智能手机和平板电脑,由 Google 公司和开放手机联盟领导及开发。尚未有统一中文名称,中国大陆地区较多人使用 "安卓" 或 "安致"。
最近的项目中遇到一个非常头痛的需求,在 Android 端录制视频的时候动态添加像监控画面一样的精确到秒的时间信息,关键是,并不是说只在播放器的界面显示时间就可以了,而是录制到视频里面去,这个 MP4 在电脑上播放也能看到每个画面的时间。
最后想到的办法是在录制完成以后去处理这个视频。
期间参考了很多资料,比较有用的大概是 ffmpeg 和比较新的 Api mediaCodec 系列了。介于 ffmpeg 都是 C 实现,和一大堆 NDK 相关,本人不是太懂,就重点关注了 MediaCodec 系列。
参考逻辑流程图一目了然的这篇博文
MediaCodec 进行编解码的大体逻辑是这样的 (转载):
主要函数的调用逻辑如下:
MediaExtractor,MediaCodec,MediaMuxer 这三个 Api 已经可以很多多媒体处理工作了,比如用 MediaExtractor+MediaMuxer 就可以做音视频剪辑,MediaCodec+MediaMuxer 就可以做自定义的录像机,一起用就可以做特效编辑,滤镜之类的了。
添加时间水印效果
关键在于取到的数据帧,是 YUV 格式的,根据拍摄时选取的不同还不一样,我用到的 NV21 格式,也就是 YUV420sp,拿到 NV21 格式的帧以后,转成 RGB 渲染,然后又转回 NV21 交给 encoder,看起来好笨重,也非常地耗时,但我还没找到更好的办法。
- private Bitmap first;
- private void handleFrameData(byte[] data, MediaCodec.BufferInfo info) {
- //YUV420sp转RGB数据 5-60ms
- ByteArrayOutputStream out = new ByteArrayOutputStream();
- YuvImage yuvImage = new YuvImage(data, ImageFormat.NV21, srcWidth, srcHeight, null);
- yuvImage.compressToJpeg(new Rect(0, 0, srcWidth, srcHeight), 100, out);
- byte[] imageBytes = out.toByteArray();
- //旋转图像,顺便解决电脑上播放被旋转90度的问题 20-50ms
- Bitmap image = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
- Bitmap bitmap = rotaingImageView(videoRotation, image);
- image.recycle();
- //渲染文字 0-1ms
- Canvas canvas = new Canvas(bitmap);
- canvas.drawText(videoTimeFormat.format(videoFirstTime + info.presentationTimeUs / 1000), 10, 30, paint);
- //预览处理帧 0-5ms
- first = bitmap;
- handler.sendEmptyMessage((int) (info.presentationTimeUs / 1000));
- synchronized (MediaCodec.class) {//记得加锁
- timeDataContainer.add(new Frame(info, bitmap));
- }
- }
- /*
- * 旋转图片
- * @param angle
- * @param bitmap
- * @return Bitmap
- */
- public Bitmap rotaingImageView(int angle, Bitmap bitmap) {
- //旋转图片 动作
- Matrix matrix = new Matrix();
- matrix.postRotate(angle);
- // 创建新的图片
- return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
- }
然后是转回 NV21
- /**
- * 获取夹了时间戳的的数据
- *
- * @return
- */
- private Frame getFrameData() {
- synchronized(MediaCodec.class) { //记得加锁
- if (timeDataContainer.isEmpty()) {
- return null;
- }
- //从队列中获取数据
- Frame frame = timeDataContainer.remove(0); ////取出后将此数据remove掉 既能保证PCM数据块的取出顺序 又能及时释放内存
- //转回YUV420sp 120-160ms
- frame.data = getNV21(dstWidth, dstHeight, frame.bitmap);
- return frame;
- }
- }
- public static byte[] getNV21(int width, int height, Bitmap scaled) {
- int[] argb = new int[width * height];
- scaled.getPixels(argb, 0, width, 0, 0, width, height);
- byte[] yuv = new byte[width * height * 3 / 2];
- encodeYUV420SP(yuv, argb, width, height);
- scaled.recycle();
- return yuv;
- }
- /**
- * 将bitmap里得到的argb数据转成yuv420sp格式
- * 这个yuv420sp数据就可以直接传给MediaCodec,通过AvcEncoder间接进行编码
- *
- * @param yuv420sp 用来存放yuv420sp数据

- * @param width 图片width
- * @param height 图片height
- */
- public static void encodeYUV420SP(byte[] yuv420sp, int[] argb, int width, int height) {
- final int frameSize = width * height;
- int yIndex = 0;
- int uvIndex = frameSize;
- int a,
- R,
- G,
- B,
- Y,
- U,
- V;
- int index = 0;
- for (int j = 0; j < height; j++) {
- for (int i = 0; i < width; i++) {
- // a = (argb[index] & 0xff000000) >> 24; // a is not used obviously
- R = (argb[index] & 0xff0000) >> 16;
- G = (argb[index] & 0xff00) >> 8;
- B = (argb[index] & 0xff) >> 0;
- // well known RGB to YUV algorithm
- Y = ((66 * R + 129 * G + 25 * B + 128) >> 8) + 16;
- U = (( - 38 * R - 74 * G + 112 * B + 128) >> 8) + 128;
- V = ((112 * R - 94 * G - 18 * B + 128) >> 8) + 128;
- // NV21 has a plane of Y and interleaved planes of VU each sampled by a factor of 2
- // meaning for every 4 Y pixels there are 1 V and 1 U. Note the sampling is every other
- // pixel AND every other scanline.
- yuv420sp[yIndex++] = (byte)((Y < 0) ? 0 : ((Y > 255) ? 255 : Y));
- if (j % 2 == 0 && index % 2 == 0) {
- yuv420sp[uvIndex++] = (byte)((V < 0) ? 0 : ((V > 255) ? 255 : V));
- yuv420sp[uvIndex++] = (byte)((U < 0) ? 0 : ((U > 255) ? 255 : U));
- }
- index++;
- }
- }
- }
看到上面的代码执行耗时,根本不可能实时录制时处理,就算后台服务处理,3 秒钟的 720*480 视频得花费约 20 秒..
解码与编码的地方也有很多, 比如编码器在某些手机不支持颜色格式, 为了适配更多机型, 颜色格式的设置以后需要更换。
- /**
- * 初始化编码器
- */
- private void initMediaEncode(String mime) {
- try {
- MediaFormat format = MediaFormat.createVideoFormat(MediaFormat.MIMETYPE_VIDEO_AVC, dstWidth, dstHeight);
- format.setInteger(MediaFormat.KEY_BIT_RATE, 1024 * 512);
- format.setInteger(MediaFormat.KEY_FRAME_RATE, 27);
- format.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible);
- // format.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Planar);
- format.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 1);
- mediaEncode = MediaCodec.createEncoderByType(MediaFormat.MIMETYPE_VIDEO_AVC);
- mediaEncode.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);
- } catch (IOException e) {
- e.printStackTrace();
- }
- if (mediaEncode == null) {
- JLog.e(tag, "create mediaEncode failed");
- return;
- }
- mediaEncode.start();
- }
补充:匹配大部分手机的颜色模式应该是 MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420SemiPlanar=21, 这个颜色格式是在 decode 解码首 buffer 的时候得到的, 但这个 format 居然没有码率,关键帧间隔,以及 FPS 等,这些只能根据自己情况设
为什么我之前用了 YUV420Flexible,android 源码里面说的 YUV420SemiPlanner 弃用
@deprecated Use {@link #COLOR_FormatYUV420Flexible}。
public static final int COLOR_FormatYUV420SemiPlanar = 21;
不过现在可以从源文件首 buffer 里面解码读取出来
- case MediaCodec.INFO_OUTPUT_FORMAT_CHANGED:
- MediaFormat format = mediaDecode.getOutputFormat();
- Log.d(tag, "New format " + format);
- if (format != null && format.containsKey(MediaFormat.KEY_COLOR_FORMAT)) {
- videoColorFormat = format.getInteger(MediaFormat.KEY_COLOR_FORMAT);
- Log.d(tag, "decode extract get videoColorFormat =" + videoColorFormat);//解码得到视频颜色格式
- }
- initMediaEncode(videoColorFormat);//根据颜色格式初始化编码器
- break;
