Playing movie in texture
Hi,
I have been away from this topic for a long while, doing other things (like this: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=12953
)
But I have found the solution to the problem that the movie hangs on the (first) frame. And it is embarassingly simple .....
You just have to add another mesh to the scene. I used an addAnimatedMeshSceneNode with a .x file. Position and texture don't matter. After that the movie playes perfectly.
The cause of the problem lies (I think) in the updating of the texture after Buf->unlock(); is called. The video driver (OpenGL in my case) doesn't get a signal to update the texture.
I stumbled upon this solution when trying to create a movie player class using the avi player from the video-for-windows library. My class uses the same basic (and brilliant) idea to read frames and memcopy these into the irrlicht texture.
Drawback is of course the fact that you can only load avi's. Big advantage is performance. With the direct show code I got about 135 FPS. The vfw-avi code gave well over 1000 FPS
Both examples with exactly the same setup and no visible difference in quality.

are you going to post your avi class to the fourm, and if so could i merge
it with my new Magic3D Library,ofcourse i will cridte it for you.
thanks

Sure. Posting code is no problem. Nor is using it in your Magic3d lib. I just had to clean it up a bit first.
There is however a to do list, so this code is not complete yet:
- fix code to run with dx9 : error locking texture
- running 2 or more avi's simultaneously
- gettting the texture mapped onto any mesh instead of the CSampleSceneNode. Maybe you have some ideas for this Emil ?
- speed up the 'memcopy' code further
Include 'vfw32.lib' under linker options. It can be found in: Microsoft Platform SDK for Windows Server 2003 R2

the error of locking texture in Dx9 was take place because you but the
unlock function inside if statment block so here is the correct code
but i do not successe get this code to work,i have to study your class
well then may i found the problem.

Hi emil,
You were right about the cause of the dx9 texture locking problem. However, the solution you proposed has a serious performance impact. I have rewritten the DrawMovie function and also got rid of all the multiplications in the memcopy code. With a sample avi file running at 15 frames per second, Irrlicht runs at more than 1100FPS (OpenGL) / 1300FPS (DX9)
The To Do list has changed a bit:
- adding sound support
- gettting the texture mapped onto any mesh instead of the CSampleSceneNode
- create an IReadFile interface for the avi file
- running 2 or more avi's simultaneously
Any suggestions are much appreciated.

Hi evo:
i have just made a small speed test to see that which is faster,
the CMovieMesh (relies on DirectShow) or CAviMovieMesh (relies on your avi vfw system).
i got those resultes
. CMovieMesh
==========
with DX9 fps = 411
with OpenGL fps = 406
. CAviMovieMesh
============
with DX9 fps = 260
with OpenGL fps = 150
here is the code of testing,using my Magic3D library
so you can play many movies as you want.
thanks

Hi,
Good to to see that there is some improvement in speed. What causes the difference compared to my results I don't really know. Maybe the test avi file that I use has a compression (Indeo 5.11) that is harder to handle for dshow than for vfw ??
Showing multiple avi's and on arbirtary meshes works for me now. What is also really cool is replacing the skybox textures with a movie, like this:
The To Do list now only has:
- add audio
- add IReadFile interface
Not the easiest item's I am afraid

Hi evo:
nice example,i wil put it with Movies examples of Magic3D Library and Credit it for you.
i have added new DrawMovie function to allows us to only copy a certain rectangle of the movie to any location in the texture.
so you could draw the movie to a certain part of any texture of SkyBox.

Code: Select all
void CMovie::DrawMovie(int x,int y,int mx,int my,int mw,int mh,video::ITexture* Buf)
{
if(flg)
{
s32* pBits =(s32*) Buf->lock();
LONG Pitch = Buf->getPitch()>>2;
DDSURFACEDESC ddsd;
ddsd.dwSize=sizeof(DDSURFACEDESC);
((IDirectDrawSurface*)pSurface)->Lock( NULL,&ddsd, DDLOCK_SURFACEMEMORYPTR | DDLOCK_WAIT , NULL);
LONG Spitch = ddsd.lPitch>>2;
//int wmin=(Pitch<Spitch)?Pitch:Spitch;
for(int h=my; h<mh; h++)
{
// memcpy((BYTE*)pBits+((y+h)*Pitch)+x*4,(BYTE*)ddsd.lpSurface+h*ddsd.lPitch,wmin);
s32* pdst = pBits+x+(y+h)*Pitch;
s32* psrc = (s32*)ddsd.lpSurface+h*Spitch;

*pdst++ = *psrc++ | 0xFF000000;
}
((IDirectDrawSurface*)pSurface)->Unlock(NULL);
Buf->unlock();
}
}actually when i was developing movie class ,i found that ,the sound of any midea has it's own speed playing and if we changed that it will play in unnormal rate, so i ahve decided to disable any sound.The To Do list now only has:
- add audio

Hi,
I am going to play around with the sound stream a bit. My idea is to let sound always play at normal 'speed'. The problem will then lie in synchronizing sound with video.
Copying part of a video can be useful. Maybe you can make 2 overloaded functions. One with and one without selection of a rectangle. Also it could be helpful to users of the magic library if you add more desciptive argument names. For instance:
DrawMovie(core::vector2d texture_upper_left_corner, core::vector2d Movie_upper_left_corner, u16 Movie_Height, u16 Movie_Width, video::ITexture* Buf)
I think the assignment of the texture can be done in the LoadMovie function. Unless you plan to change the output texture at run-time.
To be continued ... after some vacation time

totally agree with you,the problem is in synchronizing sound with video,I am going to play around with the sound stream a bit. My idea is to let sound always play at normal 'speed'. The problem will then lie in synchronizing sound with video.
and if we change the rate of the sound it will be not good.
already done.Maybe you can make 2 overloaded functions. One with and one without selection of a rectangle
good idea ,i will do it.add more desciptive argument names
i think that by this way you could apply the same movie to more than one texture.I think the assignment of the texture can be done in the LoadMovie function. Unless you plan to change the output texture at run-time.
have a nice time.To be continued ... after some vacation time
