Android ffmpeg：使用来自drawable或assets文件夹的水印图像

Question

如何使用Android中drawable文件夹或assets文件夹中的图像作为水印。

我发现了很多带有命令的示例，但所有示例都使用内部存储的静态图像路径。

我已经完成了以下代码来制作带水印的视频。

    try {
        FFmpeg ffmpeg = FFmpeg.getInstance(mContext);
        // to execute "ffmpeg -version" command you just need to pass "-version"

        String mSelectedPath = PathUtils.getPathFromUri(mContext, selectedUri);
        String mFileName = PathUtils.getFileName(mSelectedPath);
        final String mDestinationPath = "/storage/emulated/0/" + mFileName;

        String[] array = new String[]{"-i", mSelectedPath , "-i", "/storage/emulated/0/logo.png", "-filter_complex", "[0:v][1:v]overlay=main_w-overlay_w-10:10", "-codec:a", "copy", mDestinationPath};

        ffmpeg.execute(array, new ExecuteBinaryResponseHandler() {

            @Override
            public void onStart() {
                Log.d(TAG, "onStart: ");
                Toast.makeText(mContext, "Preparing video...", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onProgress(String message) {
                Log.d(TAG, "onProgress: " + message);
                Toast.makeText(mContext, "Processing for compression...", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(String message) {
                Log.d(TAG, "onFailure: " + message);
                Toast.makeText(mContext, "Failed to upload, Try Again.", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onSuccess(String message) {
                Log.d(TAG, "onSuccess: " + message);
                Toast.makeText(mContext, "Uploading started", Toast.LENGTH_SHORT).show();
                mFinalUploadUri = PathUtils.getUriFromPath(mContext, new File(mDestinationPath));
                uploadVideo();
            }

            @Override
            public void onFinish() {
                Log.d(TAG, "onFinish: ");

            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        // Handle if FFmpeg is already running
        e.printStackTrace();
    }

有人知道如何使用 drawable 或 assets 文件夹中的图像作为水印吗？任何人都可以帮忙吗？

Answer 1

FFMpeg 不是 Android Environment 。Drawable 和 Assets 目录仅用于 Android 环境所以如果你想添加图像作为水印，你应该只去文件存储路径
