以编程方式将视频上传到Google云端硬盘(Android API) [英] Uploading video to Google Drive programmatically (Android API)

问题描述

我遵循了Drive API指南( https://developer.android .com/google/play-services/drive.html )，我的应用现在可以顺利上传照片了，但是我现在尝试上传视频(mp4)却没有成功.

I have followed the Drive API guide (https://developer.android.com/google/play-services/drive.html) and my app now uploads photos smoothly, but I am now trying to upload videos (mp4) without success.

有人知道如何实现这一目标吗?该视频是一个新生成的mp4文件，我具有将其存储在设备上的路径.

Does anyone know how to achieve this? The video is a newly generated mp4 file and I have the path to where it is stored on the device.

对于图片，其操作如下:

For pictures its done like this:

Drive.DriveApi.newDriveContents(mDriveClient).setResultCallback(
    new ResultCallback<DriveContentsResult>() {

@Override
public void onResult(DriveContentsResult result) {
    if (!result.getStatus().isSuccess()) {
        Log.i(TAG, "Failed to create new contents.");
        return;
    }
    OutputStream outputStream = result.getDriveContents().getOutputStream();
    // Write the bitmap data from it.
    ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
    image.compress(Bitmap.CompressFormat.JPEG, 80, bitmapStream);
    try {
        outputStream.write(bitmapStream.toByteArray());
    } catch (IOException e1) {
        Log.i(TAG, "Unable to write file contents.");
    }
    image.recycle();
    outputStream = null;
    String title = Shared.getOutputMediaFile(Shared.MEDIA_TYPE_IMAGE).getName();
    MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
        .setMimeType("image/jpeg").setTitle(title)
        .build();
    Log.i(TAG, "Creating new pic on Drive (" + title + ")");

    Drive.DriveApi.getFolder(mDriveClient,
        mPicFolderDriveId).createFile(mDriveClient,
        metadataChangeSet, result.getDriveContents());
        }
    });
}

我感兴趣的是File的替代方案，在这种情况下，它指向"video/mp4".

What I am interested in is an alternative for a File, in this case pointing to a "video/mp4".

推荐答案

在此不加赘述，仅提供一些指针:

Without getting into much detail, just a few pointers:

您要上传的任何内容(图片，文字，视频等)都来自

Anything you want to upload (image, text, video,...) consists from

1. 创建文件
2. 设置元数据(标题，MIME类型，描述等)
3. 设置内容(字节流)

您提到的演示使用图像(JPEG字节流)进行处理，而您需要对视频进行处理.因此，您需要实施的更改是:

The demo you mention does it with an image (JPEG bytestream) and you need to do it with video. So, the changes you need to implement are:

• 将"image/jpeg" MIME类型替换为您所需的一种 视频
• 复制视频流( outputStream.write(bitmapStream.toByteArray())... )

• replace the "image/jpeg" MIME type with the one you need for your video
• copy your video stream (outputStream.write(bitmapStream.toByteArray())...)

到内容.

这些是您唯一需要进行的更改. Google Drive Android API不在乎您的内容和元数据，只是抓住了它就把它推到了Google Drive中.

These are the only changes you need to make. Google Drive Android API doesn't care what is your content and metadata, it just grabs it a shoves it up to Google Drive.

在Google云端硬盘中，应用程序(网络，Android等)读取元数据和内容，并进行相应处理.

In Google Drive, apps (web, android,...) read the metadata and content, and treat it accordingly.
