Delphi XE2：firemonkey使用libvlc播放视频吗？ [英] Delphi XE2: firemonkey playing video with libvlc?

问题描述

我仍在尝试使用带libvlc的DirectX API在firemonkey上播放视频！我已经以不同的方式播放视频，但是我想在DirectX曲面上播放视频。

请先查看此链接： http://forum.videolan.org/viewtopic.php?f=32&t=82618

有人写了一个关于如何在DirectX上使用libvlc的delphi代码，该代码运行良好，但是此代码是纯Directx代码。我想将此代码集成到firemonkey！我该如何使用firemonkey库来做到这一点（我也知道Windows的firemonkey也使用DirectX库，但是firemonkey库（接口，类，对象）的命名和使用方式与DirectX完全不同！

我现在所在的位置：

我几乎使用 Winapi.Direct3D9，Winapi.D3DX9，FMX.Context.DX9库将此纯Directx代码集成到firemonkey中。 p>

我可以在firemonkey上下文中访问IDirect3DDevice9对象！

  var 
设备：IDirect3DDevice9; 
开始
设备：= TCustomDirectXContext（TCustomForm3D（ParentForm）.Context）.Device; 
 Device.CreateTexture（video_width，video_height，1，D3DUSAGE_DYNAMIC，D3DFMT_A8R8G8B8，D3DPOOL_FA vlcVideoTexture，nil）; 
 Device.CreateTexture（video_width，video_height，1，0，D3DFMT_A8R8G8B8，D3DPOOL_SYSTEMMEM，vlcMemoryTexture，nil）; 
 end; 
  

此处完全可以在firemonkey中工作，但是您会看到此代码类型的结果对象是IDirect3DTexture9，该对象包含视频的帧缓冲区，我只需要将该对象呈现给firemonkey形式的控件即可。

如何在Firemonkey画布上绘制此缓冲区？

我正在等待好的delphi开发人员解决方案。

谢谢

解决方案

我不认为可以用LibVlc尝试Direct3D，因为libvlc请求向任何窗口播放视频的句柄，因为它们具有有效的句柄，所以可以任何形式播放。

I am still trying to play video on firemonkey using directx api with libvlc! I have played video using by different way already but I want to play video on directx surface.

please looked this link first : http://forum.videolan.org/viewtopic.php?f=32&t=82618

someone write a delphi code about how to use libvlc on directx and that code working well, but this code is pure directx code. I want to integrate this code to firemonkey! How can I do it with firemonkey library(I know for windows firemonkey using directx library too but firemonkey libraries (interfaces, classes, objects) naming and using so different then directx!

Where I am now:

I almost integrate this pure directx code to firemonkey using with "Winapi.Direct3D9, Winapi.D3DX9, FMX.Context.DX9" libraries

I can access to IDirect3DDevice9 object in firemonkey Context!

var
   Device: IDirect3DDevice9;
begin
   Device := TCustomDirectXContext(TCustomForm3D(ParentForm).Context).Device;
   Device.CreateTexture(video_width, video_height, 1, D3DUSAGE_DYNAMIC, D3DFMT_A8R8G8B8, D3DPOOL_DEFAULT, vlcVideoTexture, nil);
   Device.CreateTexture(video_width, video_height, 1, 0, D3DFMT_A8R8G8B8, D3DPOOL_SYSTEMMEM, vlcMemoryTexture, nil);
end;

That code in here working completely in firemonkey but you will see the result object of this code type is IDirect3DTexture9 , this object contains frame buffer of video, i just need to render this object to on some control in firemonkey form.

How can I draw this buffer to firemonkey canvas?

I am waiting good delphi developers solutions.

Thanks

解决方案

I do not think trying direct3D with LibVlc is possible since libvlc request handle to any window to play video, playing on any form is ok since they have valid handle.
