In my app, I already integrated with google login and I successfully accessed my google drive folder and video files(mp4). But better player can play public video by modified url like this https://drive.google.com/uc?id=my_video_file_id.
I want to develop an app like Nplayer or Kudoplayer.
Can anyone guide me some scenario of Nplayer or Kudoplayer? and guide me how to play private drive's video using better player. Thanks.
Finally I got solution after research for a long time :-)
Summary answer for this question
Don't forget to add headers in BetterPlayerDataSource
Don't use this format "https://drive.google.com/uc?export=view&id=${fileId}" and
Use this format "https://www.googleapis.com/drive/v3/files/${fileId}?alt=media"
For guys who face issue like me, please follow these step
Enable Drive API
Integrate google login in your app with appropriate Scpoe, for me driveReadonlyScope is enough.
Retrieve fileId
Next step that I stuck is
Don't forget to add headers in BetterPlayerDataSource
Don't use this format "https://drive.google.com/uc?export=view&id=${fileId}" and
Use this format "https://www.googleapis.com/drive/v3/files/${fileId}?alt=media"
Like this
BetterPlayerDataSource betterPlayerDataSource = BetterPlayerDataSource(
BetterPlayerDataSourceType.network,
"https://www.googleapis.com/drive/v3/files/$fileId?alt=media",
videoExtension: ".mp4",
headers: getDataFromCache(CacheManagerKey.authHeader),
);
authHeader can get when you call signWithGoogle function,
I save it and retrieve later. In signWithGoogle function, you can get authHeader using this
Map<String, String> authHeader = await googleSignIn.currentUser!.authHeaders;
Bonus - Queries For You.
Get Share With Me Data = > q: "'sharedWithMe = true and (mimeType = 'video/mp4' or mimeType = 'application/vnd.google-apps.folder')"
Get Share Drive Data => q: "'shared_drive_id' in parents and trashed=false and (mimeType = 'video/mp4' or mimeType = 'application/vnd.google-apps.folder')",
Get My Drive Data => q: "'root' in parents and trashed=false and (mimeType = 'video/mp4' or mimeType = 'application/vnd.google-apps.folder')",
that's tricky.
I would propably try to attach approprieate headers so google drive would allow me to reach file using BetterPlayerDataSource class.
but being curious and checking how google would want it to be made... I got into spiral of google docs and I found this
https://cloud.google.com/blog/products/identity-security/enhancing-security-controls-for-google-drive-third-party-apps
Keep in mind that downloading file and streaming also differ. So if you want for your player to not lag you should stream.

Here's my issue :
I am creating a small application based on audio files stored on Google Drive, in Flutter.
I am using the drive api to make my requests, with these scopes in my google sign in :
GoogleSignIn _googleSignIn = GoogleSignIn(
scopes: [
'email',
'https://www.googleapis.com/auth/userinfo.profile',
'https://www.googleapis.com/auth/contacts.readonly',
'https://www.googleapis.com/auth/drive',
'https://www.googleapis.com/auth/docs',
'https://www.googleapis.com/auth/drive.appdata',
],
);
I have an auth element and handle signing in and out. Until then, no issues.
I can also request my files with an implementation looking like this :
var api = widget.api.getAPI();
var files = await api.files.list($fields: '*');
This works perfectly, and so does :
var api = widget.api.getAPI();
var files = await api.files.get("myFileId"); (//does get a file instance)
But since I'd like to retrieve some of the Metadata included in my audio files, and since the drive API doesn't natively support extracting audio metadata and sending it as a google metadata, I thought I'd extract it with a partial download on the file itself.
Here's the catch : I can't seem to get the partial download to work.
Based on the doc, I thought the implementation would look something like this :
import 'package:googleapis/drive/v3.dart' as ga;
(...)
try {
var partiallyDownloadedFile = await api.files.get(
"myFileIdHere",
downloadOptions: ga.PartialDownloadOptions(ga.ByteRange(0, 10))); //should get a ga.Media instance
print("partial download succeeded");
print(partiallyDownloadedFile);
//(...do stuff...)
return;
} catch (err) {
print('Error occured : ');
print(err);
return;
}
But this always throws this error :
ApiRequestError(message: Attempting partial download but got invalid
'Content-Range' header (was: null, expected: bytes 0-10/).)
I tried using it on Wav files, but also MP4 files. The error is always the same, which leads me to believe it's my implementation that's somehow wrong, but I'm not sure what I'm supposed to do to fix it. Is it my request missing the header ? The response not including it ?
While very clear, that error doesn't help me troubleshoot my issue at all. I can't seem to find any documentation on how to conduct a partial media request. I haven't found any example projects to compare it with.
PartialDownloadOptions does not have much documentation.
I could handmake a partial request through the download links (which is how I can read the music to begin with) but the drive API supposedly allows this. Could anyone familiar with Flutter/the google APIs help me correct my implementation?
EDIT : This was due to an error within the commons library in the Dart google APIs, and was (at the very least superficially) fixed thanks to Kevmoo's efforts : https://github.com/google/googleapis.dart/issues/462
It was a Content-Range error happening due to browser specifications with access-control-expose-header compared to iOS/Android-type requests that typically expose every header.
I'm trying to get the coordinates from the address which user input,using flutter_google_places but here is gives me error
{candidates: [], error_message: You must use an API key to authenticate each request to Google Maps Platform APIs. For additional information, please refer to http://g.co/dev/maps-no-account, status: REQUEST_DENIED}
here is my code
static Future<String> getPlaceId(String input) async {
final String url =
"https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=$input&inputtype=textquery&key$googleApiKey";
var response = await http.get(Uri.parse(url));
Map<String, dynamic> json = jsonDecode(response.body);
print(json);
var placeId = json['candidates'][0]['place_id'] as String;
return placeId;
}
i added the key too, but it gives me this error, please help how to do this or this is there any other to get the coordinates from user input address.
There are a few steps you have to make sure you complete. First, make sure your API key is not restricted for your device. You can either set the key to restrict none or just add your authentic key to the API key. And get the access.
Also basic stuff. Make sure all the needed SDK's are activated for your project. And It would be better if you can provide some more data. That would be kinda helpful. Also don't forget to add your api key to the xml file inside your android project. if you're doing it for android.
(BTW the issue is with your credentials. First solve that. Then you can find the way to get the coordinates. It's pretty easy. You're already there.)
I want to get data from Firestore, convert it into csv format, then share it using the user's method of choice (e.g. email). I'm using the csv package to convert the data to csv, the path_provider to get the directory to write the file to the phone, and the share_plus package to share the file.
However, when I tap a share method (e.g. Gmail, Outlook, Whatsapp), it opens the right app but then I get a message on the phone like "Unable to attach file" (but there is no error in my app). The file is definitely being written as I can read it and it comes back with the expected string. The ShareResultStatus that is returned by the share is 'successful' Can anyone figure it out what the problem is and how to fix it?
Here is my code:
Future exportData() async {
// Dummy data (in reality, this will come from Firestore)
List<List> dummyData = [
['Date', 'Piece', 'Rating'],
[DateTime.utc(2022, 05, 01), 'Sonata', 4],
[DateTime.utc(2022, 05, 02), 'Sonata', 2],
];
// Turn into CSV
String csvData = _convertToCsv(dummyData);
// Write to local disk
await _writeData(csvData);
// Share
String filePath = await _filePath;
final result =
await Share.shareFilesWithResult([filePath], mimeTypes: ['text/csv']);
print(result.status);
}
And here are the functions used in above code:
Future<String> get _filePath async {
final directory = await getApplicationDocumentsDirectory();
return '${directory.path}/my_practice_diary_data.csv';
}
Future<File> _writeData(String csvData) async {
String filePath = await _filePath;
final file = File(filePath);
return file.writeAsString(csvData);
}
String _convertToCsv(List<List> data) {
String result = const ListToCsvConverter().convert(data);
return result;
}
Note: I've tried doing it both as txt and csv files, got same result
*** EDIT (06/06/2022): After a lot of reading and watching youtube videos, I have come to realise that the problem is that the directory getApplicationDocumentsDirectory() is only accessible by my app (and hence the app that is is being shared to, like gmail, cannot read it).
For now I have worked around it by using the package mailer and using user's google credentials to send emails (I followed these helpful youtube tutorials: Flutter Tutorial - How To Send Email In Background [2021] Without Backend and Flutter Tutorial - Google SignIn [2021] With Firebase Auth - Android, iOS, Flutter Web.
However, it would still be nice to know a nice way to generate a file and share it using share_plus, as per my original question. I believe that this can be achieved via one of two ways:
Find a way to allow other apps to access this specific file in the app directory; or
Find a way to download the file into an external storage (like downloads folder), then share that. (I cannot find a way to do this on both Android and iOS).
Anyone who knows how to do these or any other solution to the problem, please share!
I have been working on Wowza Streaming Server and while trying to secure Apple HTTP Live Streaming using AES-128 - external method I am encountering below problems :
External AES-128 method of encryption is not working for .smil files present in the sub-folder of the application's source directory. I tried to achieve it by putting the [my-stream].key in [install-dir]/keys and [install-dir]/keys/[sub-folder-name] but both the scenarios failed for me to achieve this.
playlist url is :- [wowza-server-ip]:[port]/[application-name]/[applcation-instance-name]/smil:[sub-folder]/demo.smil/playlist.m3u8
In case of mp4s present in the application's source path, the player is not calling the key url.
The sequence of calls made by the player are :-
[wowza-server-ip]:[port]/crossdomain.xml
[wowza-server-ip]:[port]/[application-name]/[applcation-instance-name]/[stream-name]/playlist.m3u8
[wowza-server-ip]:[port]/[application-name]/[applcation-instance-name]/[stream-name]/chunklist_w[wowza-session-id].m3u8
[web-server-ip]:[port]/crossdomain.xml
After this player is not calling the "key request uri" as it was supposed to call. The calls are going properly when I am using the internal AES-128 method of Encryption.
My chunklist_w[wowza-session-id].m3u8 is
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:12
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-KEY:METHOD=AES-128,URI="http://[web-server-ip]:[port]/SimpleWebServlet/key.jsp?wowzasessionid=[session-id]"
#EXTINF:9.52,
media_w[session-id]_0.ts
#EXTINF:10.4,
media_w[session-id]_1.ts
[streamname].key file in [install-dir]/keys folder is
cupertinostreaming-aes128-key: DE51A7254739C0EDF1DCE13BBB308FF0
cupertinostreaming-aes128-url: http://[web-server-ip]:[port]/SimpleWebServlet/key.jsp
jsp file to return the key is key.jsp
<%# page import="java.util.*,java.io.*" %>
<%
boolean isValid = true;
if (!isValid)
{
response.setStatus( 403 );
}
else
{
response.setHeader("Content-Type", "binary/octet-stream");
response.setHeader("Pragma", "no-cache");
String keyStr = "DE51A7254739C0EDF1DCE13BBB308FF0";
int len = keyStr.length()/2;
byte[] keyBuffer = new byte[len];
for (int i=0;i<len;i++)
keyBuffer[i] = (byte)Integer.parseInt(keyStr.substring(i*2, (i*2)+2), 16);
OutputStream outs = response.getOutputStream();
outs.write(keyBuffer);
outs.flush();
}
%>
If anybody has encountered the similar problem or has successfully implemented the external aes-128 method of wowza, kindly put some light on the issues mentioned above.
EDIT 1
Kindly ignore the 2nd point as after further analysis I found out that there is some issue with the jboss delivering the key, once it delivers the crossdomain xml to the player.
For reference to this problem kindly check : Can I call two crossdomain.xml from two different servers from my flash player?
EDIT 2
Apologies for the typo in my first point. It should be .smil rather than .mp4, I have corrected the same in my first point
I recently tried out HLS with AES128 and it worked fine. My key file was in [wowzadir]/keys/mystream.key. Looks like it is your player that does not do something right here. Which player are you using?
You can try to use wget to download some chunks and you can inspect them with VLC for example to see if the encryption was applied.
I need to upload to multiple s3 buckets with filepicker.io. I found a tweet that indicated that there was a hacky, but possible, way to do this. Support hasn't gotten back to me yet, so I'm hoping that someone here already knows the answer!
Have you tried generating a second application/API key? It looks like they lock your S3/AWS credentials to an application/API key rather than directly to the account.
Support just got back to me. There's no way to do this besides creating multiple applications, which is okay if you are just switching between prod/staging/dev, but not a good solution if you have to upload to arbitrary buckets.
My solution is to execute a PUT request with the x-amz-copy-source header after the file has been uploaded, which copies it to the correct bucket.
This is pretty hacky as it request two extra requests per file -- one filepicker.stat and one more call to s3 (or your server).
#Ben
I am developing code with same issue of files needing to go into many buckets. I'm working in ASP.net.
What I have done is have one Filepicker 'application' with it's own S3 bucket.
I already had a callback to the server in the javascript onSuccess() function (which is passed as a parameter to filepicker.store()). This callback needed to be there to do some book-keeping anyway.
So I have just added in an extra bit to the server-side callback code which uses the AWS SDK to copy the object from the bucket filepicker uploades it to, to it's final destination bucket.
This is my C# code for moving, or rather copying, an object between buckets:
public bool MoveObject(string bucket1, string key1, string bucket2, string key2 = null)
{
bool success = false;
if (key2 == null) key2 = key1;
Logger logger = new Logger(); // my logging system
try
{
RegionEndpoint region = RegionEndpoint.EUWest1; // use your region here
using (AmazonS3Client s3Client = new AmazonS3Client(region))
{
// TODO: CheckForBucketFunction
CopyObjectRequest request = new CopyObjectRequest();
request.SourceBucket = bucket1;
request.SourceKey = key1;
request.DestinationBucket = bucket2;
request.DestinationKey = key2;
S3Response response = s3Client.CopyObject(request);
logger.Info2Log("response xml = \n{0}\n", response.ResponseXml);
response.Dispose();
success = true;
}
}
catch (AmazonS3Exception ex)
{
logger.Info2Log("Error copying file between buckets: {0} - {1}",
ex.ErrorCode, ex.Message);
success = false;
}
return success;
}
There are AWS SDKs for other server languages and the good news is Amazon doesn't charge for copying objects between buckets in the same region.
Now I just have to decide how to delete the object from the filepicker application bucket. I could do it on the server using more AWS SDK code but that will be messy as it leaves links to the object in the filepicker console. Or I could do it from the browser using filepicker code.
