Play Video From Uint8list

[mohammadinfo]

I have an encrypted video that is very important, and I need to ensure its security. I download the video and then decrypt it. I want to save the decrypted file on the RAM rather than on the hard drive to make it inaccessible. What can I do? I want the decrypted file to go to RAM, and I want the video player to read it from there.

[wang-bin]

Currently not supported. Play when the whole file is saved? It will be easy to support.

[mohammadinfo]

I want a file to be temporarily saved, played by a video player, and then quickly deleted. However, Windows says the file is in use and cannot be deleted. I want it to read the file, take whatever it needs into RAM, and then remove any accessibility to the file, or find a way to make sure the user cannot access the file.

[wang-bin]

If you have a uint8list contains the whole file content, i can add a new url type, get the address and size from the url(for example 'mem://$addr+$size') and play it

[mohammadinfo]

I want exactly this: I first save the file, then convert it to a Uint8List, and I want it to have the capability to play the video from a Uint8List.

[mohammadinfo]

Sorry, when will the upgraded package be available ?

[mohammadinfo]

I kindly request information regarding the release date for the upgraded package. My project is currently pending, awaiting the availability of your package.

[wang-bin]

download the latest https://sourceforge.net/projects/mdk-sdk/files/nightly/mdk-sdk-windows-desktop-vs2022-x64.7z/download

import 'dart:ffi';
import 'package:ffi/ffi.dart';

Uint8List data = ...;
final cdata = calloc<Uint8>(data); // must be alive when playing
cdata.asTypedList(data.length).setRange(0, data.length, data);
_controller = VideoPlayerController.networkUrl(Uri.parse('mem://${cdata.address}+${data.length}'));
...
// release c heap after player disposed
await _controller.dispose();
calloc.free(cdata);

[mohammadinfo]

Without update your package is it work ?

[wang-bin]

yes, no change in fvp

[mohammadinfo]

Thanks 👍

[wang-bin]

I need the full log

[mohammadinfo]

final cdata = calloc<Uint8>(data.length);

[wang-bin]

full log please. if fail to open a stream, the exceptions are the same, only the log tells the detail

I can't see libmdk version in your log. Do you set logger before registerWith()?

using the old mdk.dll

[mohammadinfo]

I replaced it, but I think when I build, it still uses the old version of the package. I believe you should update to the new version.

[mohammadinfo]

Could you please replace updated mdk.dll in your package?

[wang-bin]

You can delete fvp from cache, then fvp and it's last dependency will be download again. Run flutter pub cache clean or delete fvp cache dir if you know where it is.

[mohammadinfo]

Okay thank you very much indeed.

[wang-bin]

Some videos can not play correctly for me in flutter. But in a c/c++ app, mem: works perfectly. I don't know the reason now.

Another way to play uint8list is using base64 data url, previous versions are supported

final b64uri = 'data:application/octet-stream;base64,${base64Encode(data)}';
_controller = VideoPlayerController.networkUrl(Uri.parse(b64uri));

But seek() seems broken.

[mohammadinfo]

For me it's okay but I'll test it again, thanks bro... You saved my life 😁🙏🏻
