Wanted to know if any of you guys have played around with getting a video to play in a mini app? I have looked at some of the Alipay documentation and from what I can see there is only one supported platform to upload a video to in order to use within the mini app...
You cant get videos to play in native mini programs because the tag is not currently supported.
You could get videos to play by making use of the web-view which points to a website which hosts the video
Is there any solution to take picture using the laptop camera with Flutter desktop (on Windows)?
I don't want to use go-flutter.
You would need to write a plugin that implements it using Windows APIs.
Since the Texture widget isn't supported for Windows yet, you would need to use a separate native window for any live preview UI.
use camera_windows 0.1.0+1, the official plugin

The task:
OS: Mac OS X 10.9 +
Description:
There is web-camera connected to a Mac via USB. I need to discover a way of getting access to its' brightness, pan, color temperature, focus, etc.
I also need a way to apply image filters against camera's video stream.
I need to be able to control the camera while it is being used by other programs like Skype, so I can transmit for example video stream with increased contrast at Skype video call.

Solution:
This is the question.
As far as I understood I must to find custom kext (driver) in order to perform all this magic.
Could you please show me right direction, libraries, drivers, etc.
You can use opencv library to capture camera frames, apply filters, etc.
http://docs.opencv.org/2.4/doc/tutorials/introduction/display_image/display_image.html
Then you can feed a virtual cam that can feed into Skype, etc.

There also many open source virtual webcam available.
I hope this helps.
Is there a way for my Windows program to get notifications when a video device is in use. I know how to enumerate the devices using http://msdn.microsoft.com/en-us/library/dd377566(v=vs.85).aspx
I can also use ffmpeg to open the video device to check if it is available but it opens up the camera for that fraction of a time which I don't want.
Any help will be appreciated. Thanks.
you can use physical device object name of camera and use sysinternals handle utility to search for handle usage of camera

to downlaod handle utility
