In some sense, the codec is like the key and your video is like a locked file. In simple terms, it is software that knows how to convert the video into a viewable state. You know what a media player is-but what is a codec?
As mentioned above, and I'm also asking on the VLC's own repo for direct3d advice and trying to help them, if we had the ability to create child Window's in MAUI and not just new top level windows, we could solve this problem instantly.To play any video file that exists in the wildest corners of the web you need two things: I haven't messed with Direct3D since D3D9 came out, so maybe D3D11 allows restricting rendering to certain area's in an HWND and not clearing the whole HWND before presenting a new frame. Creating a swap chain against an HWND on Direct3D will clear the whole HWND.
If there's the ability to make them a child of a Window in MAUI, then we could create a whole new child window and use that as the VLC render target and have perfect coordinates etc.Īfter visiting the direct3d docs since it's been quite some time, it doesn't seem like its possible to solve the issue with a single parent native window. MAUI supports multiple windows, but I'm not sure if theyre new W'S_OVERLAPPEDWINDOW's or WS_CHILD's on Win32. Maybe we can just create a custom VideoView implementation based on IVideoView There's also VideoView that UWP, WPF, Uno, etc. That way it can use the information from IView for width/height and what not. What we need is a PR or fork of LibVLC and LibVLCSharp that has an IView property in MediaPlayer which will make it support MAUIs virtual view style composition. We would have to figure out a way to move it, right? It looks like VLC only supports scaling of a video, which is fine, but we would have to figure out the scale by taking the View's Rect information in relation to the parent HWND's RECT information and calculate a scale factor, but if that even works, VLC probably will render to the HWND's top left corner.
In the case of Windows, assuming the HWND returned by () is where all of the views are composed to, that should be good enough for MediaPlayer.HWnd if MediaPlayer allows specifying constraint Rect(the IView's width/height etc.) possibly.
