need help regarding event

i've come across trouble again this time.

my problem :

Code:

---


i want to make a Movie Player using Micorost.directx.audiovideoplayback.dll
whats make it trouble is => i want to double click to make it fullscreen.. or i can say do an event.

---

for now i place my audiovideoplayback Video in a panel.
but when i do double click even on the panel, it wont work..
so i was wondering if there any way to make a panel can be double clicked even if a component covered by other component.

i guess word alone wont help
so here the code

this was made 100% pure coding. except the timer. i dragdrop it
the timer only used to make the seekbar to follow the following position/max position of video

why i use directx instead of wmplib?
because directx can play all type of video while wmplib cant.

Try commenting out video.Play(). Does it work then? It could be that some funky interaction is the culprit here. Do the other events you hooked up on the videoFrame work? The Video class is not a control, so it doesn't really cover your panel.

BTW, if that is the problem, maybe you could use the render-to-texture facilities of the video class?

I know that, smarty pants! :rolleyes:
I suggested that as an experiment to verify if the call to video.Play() is indeed the source of the problem. I was thinking that, for some reason, the way that the video is rendered to the control somehow interferes with the normal windows message loop, which results in certain events not being raised at all.
My question was: if you comment out that line, do the events work as expected? This will help you rule out other potential causes of the problem.

Honestly, I currently don't know, and won't know for sure until I find time to experiment with the API myself. But from what I could gather from the documentation (here, and here), it should be something along these lines:

• The idea is to render the video to an off-screen texture, and than display that texture on a quad rendered in the viewport.
• So, you'll need to add a reference to Microsoft.DirectX.Direct3D, and create a Device instance. You might want to search for some tutorials to help you with that.
• After you setup your device, you need to define a quad (two triangles), assign positions and UV texture coordinates to the vertices, so that the quad covers the entire client area of your videoFrame; the texture should fit exactly onto the quad. There should be some tutorials out there on that too.
• Then you would call video.RenderToTexture(device) to enable the video object to trigger the TextureReadyToRender events whenever a frame is rendered.
• Assign an event handler to the TextureReadyToRender event; the TextureRenderEventArgs contain a member property named Texture, that should contain your rendered frame. The event handler would then set that texture to the device, and render the quad.
• This should enable the click event to function normally - but I'm not sure; you'll need to test it.
