我尝试压缩从图库中挑选的视频文件，使用SiliCompressor（https://github.com/Tourenathan-G5organisation/SiliCompressor）对其进行压缩并上传到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？我会很高兴得到任何帮助，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());
}
});
}
}
压缩视频的结果文件路径无效。当我打开链接时，应该保存压缩视频，没有什么。

答案 0 :(得分：0)
将以下代码放在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());
}
