libtheoraplayer hangs on destruction

[TexelOne]

Hi,

 

I made a function that plays an intro video (until the video ends or the user hits the escape key) using the code from Paramecij's example of libtheroaplayer (found here).

 

If I exit the loop by hitting the escape key, the TheoraManager destruction works fine and the program continues. But if the loop exits by the video reaching its end, the game hangs on the manager's destruction.

 

Shouldn't the manager's destruction work the same, no matter how the loop exits?

 

Here's the code:

//IntroVideo.CPP

#pragma comment(lib,"libtheoraplayer.lib")
#pragma comment(lib,"opengl32.lib")
#pragma comment(lib,"openal32.lib")

#include "engine.h"
#include <gl/gl.h>
#include "TheoraVideoManager.h"
#include "TheoraVideoFrame.h"
#include "OpenAL_AudioInterface.h"

void showIntroVideo (short int &gState) {
  TWorld	world = CreateWorld();
  TBuffer gbuffer = CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);
  TCamera camera = CreateCamera();

  //Theora setup
  TheoraVideoManager *mgr = new TheoraVideoManager();
  OpenAL_AudioInterfaceFactory *openAIF = new OpenAL_AudioInterfaceFactory();
  mgr -> setAudioInterfaceFactory(openAIF);
  mgr -> setDefaultNumPrecachedFrames(32);
  TheoraVideoClip *clip = mgr->createVideoClip( "bunny.ogg",TH_RGB,0,1);
  clip -> setAutoRestart(false);
  float w = clip->getWidth();
  float h = clip->getHeight();
  TTexture videotexture = CreateTexture( w, h, TEXTURE_RGB );

  //video player loop:
  while (!KeyHit(KEY_ESCAPE) && !clip->isDone()) {

     //Update texture: 
     TheoraVideoFrame *f = clip->getNextFrame();
     if(f){
        BindTexture(videotexture);
        glTexImage2D(GL_TEXTURE_2D,0, GL_RGB, w-1, h-1, 0, GL_RGB, GL_UNSIGNED_BYTE, f->getBuffer());
        clip->popFrame();
     }

     //Update:
     mgr->update(AppSpeed());
     UpdateAppTime();
     UpdateWorld(AppSpeed()) ;

     //Render:
     SetBuffer(gbuffer);
     RenderWorld();
     SetBuffer(BackBuffer());
     RenderLights(gbuffer);
     DrawImage(videotexture,0,0,GraphicsWidth(),GraphicsHeight() );

     Flip() ;
  }

  delete mgr; //<---------- Hangs on destruction!
  delete openAIF;

  FreeEntity(videotexture);
  FreeEntity(camera);
  FreeWorld(world);

  //Set gameState to 2 (main Menu)
  gState = 2;
  return;
}

 

Both Paramecij and Niosop's code I've found destroys the manager (and everything else) by calling Terminate() and exiting the app, but I need the game to continue running after playing the intro video .

 

Any thoughts on why it might hang?

 

Thanks in advance!
