LibTheora video

[AggrorJorn]

I am at a point where I want to add video into my project. Now I know that Niosop made this great video library for Lua called LibTheora player. However I recall there was this video about it how to use it, but I can't seem to find it.

 

I am trying to get the video's to play inside as well as outside the editor, but with no luck.

Does anybody have a working Lua example of how things work?

 

Steps taken so far:

1. extracted the lib theora file,shaders, lua scripts in to the game project.
   
2. added a .ogg video inside the project
   this code:
   

   require("Scripts/constants/keycodes")
   require("Scripts/math/math")
   require("Scripts/video")
   
   
   RegisterAbstractPath("")        
   Graphics(1440,900,32)        
   fw=CreateFramework()        
   
   
   cube = CreateCube()
   cube:SetPosition(Vec3(0,0,5))
   
   video = TheoraClip:new()
   videoMat:CreateMaterial("video.ogg", video)
   cube:Paint(videomat)
   video:Play()
   
   while KeyHit(KEY_ESCAPE)==0 do        
   
   
          fw:Update() 
          fw:Render()
   
          Flip(0)
   end

do you have all of the dll's in the SDK's root directory? i think there are three of them...

[AggrorJorn]

Yips, I have the following files:

 

• libtheoraplayer.dll (root)
  
• letheora.dll (root)
  
• lua51.dll (root)
  
• lua5.1.dll (root)
  
• video.mat (root)
  
• video.ogg (root)
  
• nio_util.lua (inside scripts folder)
  
• video.lua (inside scripts folder)
  
• mesh_video.frag (placed inside the shader.pak/mesh folder)

Is Gimpy's tv working?

http://leadwerks.com/werkspace/index.php?/files/file/82-old-tv/

[AggrorJorn]

That comes in handy, but it crashes as soon as it is being placed in the scene.

[macklebee]

try it in an older version of LE... like 2.31, cause it worked fine there...

[AggrorJorn]

so far it has crashes in 2.4 and 2.32r5. downloading 2.31

Gimpys Old TV using Nio's video material works for me in both 2.4 and 2.32r5

[AggrorJorn]

I must be forgetting something. Do you have the same files as I do?

 

libtheoraplayer.dll (root)

letheora.dll (root)

lua51.dll (root)

lua5.1.dll (root)

video.mat (root)

video.ogg (root)

nio_util.lua (inside scripts folder)

video.lua (inside scripts folder)

mesh_video.frag (placed inside the shader.pak/mesh folder)

[Marleys Ghost]

Do you have the same files as I do?

 

 

no ... mine work

 

 

On a serious note

 

 

libtheoraplayer.dll (SDK root)

letheora.dll (SDK root)

lua51.dll (SDK root)

lua5.1.dll (SDK root)

video.mat (Materials root)

bunny.ogg (SDK root)

nio_util.lua (scripts root)

video.lua (scripts root)

mesh_video.frag (placed inside the shader.pak/mesh folder)

 

Make sure old-tv.lua does have the right path to the correct .ogg file

thx marley,

 

the editor version is working now. I made the mistake of using the abstract function for finding the video.

 

Only thing left to find out is getting it to work outside the editor.

 

require("Scripts/constants/keycodes")
require("Scripts/math/math")
require("Scripts/video")

RegisterAbstractPath("")        
Graphics(1440,900,32)        
fw=CreateFramework()        

camera = fw.main.camera
camera:SetPosition(Vec3(0,10,0))
light = CreatePointLight(10)

scene = LoadScene("abstract::scene.sbx")

---------------------------------------------
-- Video is loaded on a cube.
---------------------------------------------

cube = CreateCube()
cube:SetPosition(Vec3(0,10,5))


TheoraVideo:Init()
videoclip = TheoraVideo:CreateMaterial("video.ogg", "Videotest")
cube:Paint(videoclip,1)

videoclip:SetLoop(1)
--videoclip:Play(1)

---------------------------------------------
-- Video is loaded on a cube.
---------------------------------------------

camRotation=Vec3(0,0,0)
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2)
HideMouse(1)

while KeyHit(KEY_ESCAPE)==0 do

--Camera look
gx=Curve(MouseX()- GraphicsWidth()/2,gx,10)
gy=Curve(MouseY()- GraphicsHeight()/2,gy,10)
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2)
camRotation.x = camRotation.x+gy /10
camRotation.y = camRotation.y-gx /10	
camera:SetRotation(camRotation,1)

--keys
move   = Curve(KeyDown(KEY_W)-KeyDown(KEY_S),move,10)
strafe = Curve(KeyDown(KEY_D)-KeyDown(KEY_A),strafe,10)	
camera:Move(Vec3(strafe /11,0,move/11))	

       fw:Update() 
       fw:Render()

       Flip(0)
end

 

I am sure that there was this video or article were Niosop showed how to set this up. I have send him a message.

getting it to work outside the editor

 

 

Not 100% sure what you mean by that.

[AggrorJorn]

atm the video plays inside the editor attached via an object, but now I am trying to run it in a game script outside the editor. The video is not loaded via a lua script that belongs to a model. see the script in my reply above.
