Hi Forum,

I know I can query a certain frame of a movie file using BaseBitmap, but if I want to query all frames sequentially, how can I find out which frames to ask for. There is no way to determine the movie length, is there? Any ideas?

Best

I am not sure but I would iterate the frames in BaseBitmap::Init(). Look at code example below. The iterator i is the movielength in frames then.

  
AutoAlloc<BaseBitmap> bm;  
Bool ismovie = FALSE;  
LONG i = 0;  
  
{  
      bm->Init(fn, i, &ismovie;);  
      i++;  
}  
while(ismovie);  
  
GePrint(LongToString(i)); //i is length of movie  

hope this helps,

Matthias

Hi Matthias,

thanks for your idea. I did not actually test it, because I tried something similar (iterating until Init returns somthing != IMAGE_OK) and it did not work.

Meanwhile I found out a better way to do it, though:

Bool GeGetMovieInfo(const Filename& fn, LONG* frames, Real* fps)

Thanks!
Timm

Good to know that there is this GeGetMovieInfo function.
Some functions are to deep buried in the docs.
