android-将视频压缩到 firebase 存储

Question

我正在尝试压缩从图库中选取的视频文件，使用 SiliCompressor( https://github.com/Tourenathan-G5organisation/SiliCompressor ) 压缩并上传到 FirebaseStorage。问题是压缩视频的文件路径无效。我如何压缩视频并将其上传到 FirebaseStorage？我很乐意提供任何帮助，谢谢。

    uploadBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent pickIntent = new Intent();
            pickIntent.setAction(Intent.ACTION_GET_CONTENT);
            pickIntent.setType("video/*");
            startActivityForResult(Intent.createChooser(pickIntent, "Pick video"), RC_PICK_VIDEO);
        }
    });


        @Override
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_PICK_VIDEO && resultCode == RESULT_OK && data != null){
        final Uri filepath = data.getData();
        final String name = "VIDEO" + filepath.getLastPathSegment().toString() + ".mp4";

        mDatabaseReference = mDatabase.push();

        String compressFilePath = "";
        try {
            compressFilePath = SiliCompressor.with(MainActivity.this).compressVideo(filepath.toString(), mDatabase.toString());

        } catch (URISyntaxException e) {
            e.printStackTrace();
            Log.v("Error", e.getMessage());
        }
        StorageReference videoRef = mStorageReference.child(compressFilePath);

        videoRef.putFile(Uri.parse(compressFilePath)).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                Uri downloadedUrl = taskSnapshot.getDownloadUrl();

                String url = downloadedUrl.toString();

                getDownloadedUrl(url);   

                uploadToDatabase(name, url);

            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                int progress = (int) ((100 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount());
                Toast.makeText(getApplicationContext(), "Upload is " + progress + "% done", Toast.LENGTH_LONG).show();

            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(), "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
                Log.v("Error: ", e.getMessage());
            }
        });

    }
}

并且压缩视频的结果文件路径无效。当我打开链接时，压缩视频应该保存在哪里，什么都没有。

Answer 1

将下面的代码放在AsyncTask中

     String compressFilePath = "";
    try {
        compressFilePath = SiliCompressor.with(MainActivity.this).compressVideo(filepath.toString(), mDatabase.toString());

    } catch (URISyntaxException e) {
        e.printStackTrace();
        Log.v("Error", e.getMessage());
    }
