In first place i wish to apologize for my very bad english

I wrote a program that plays a video in a loop and the program freezes after a 2 or 3 hours

Someone can help me?

This is the code

int reproduce_video(char video[])
{
estado(2);
APEG_STREAM *stream;
int showed = 0, skipped = 0;
float speed_mult;
int x_off, y_off;
int ret;
bool primero=true;
stream = apeg_open_stream(video, 1);
if(!stream)
{
//ERROR AL ABRIR EL VIDEO
return -1;
}else{

stream->timer = -1;

while((ret = apeg_advance_stream(stream, FALSE)) == APEG_OK )
{
++showed;
stretch_blit(stream->bitmap, screen, 0, 0, stream->w, stream->h,0,0,800,600);
}

apeg_set_stream_rate(stream, 0.0);

apeg_close_stream(stream);
}
}

Same code, formatted:

1int reproduce_video(char video[])
2{
estado(2);
APEG_STREAM *stream; 
int showed = 0, skipped = 0;
float speed_mult;
int x_off, y_off;
int ret;
bool primero=true; 
stream = apeg_open_stream(video, 1); 

if(!stream)
{
  //ERROR AL ABRIR EL VIDEO
  return -1;
}
else
{
19 
  stream->timer = -1;
21 
22 
  while((ret = apeg_advance_stream(stream, FALSE)) == APEG_OK )
  {
    ++showed;
    stretch_blit(stream->bitmap, screen, 0, 0, stream->w, stream->h,0,0,800,600);
  }
    
  apeg_set_stream_rate(stream, 0.0);
  apeg_close_stream(stream);
}

33}

Can you use a debugger to find out where it freezes? Perhaps using the debug version of the lib?

the program fails after 2 or 3 hours working, thats how i cant debug the program. What can you say me about debug version of APEG Library? How can i use it? thanks...

aclaration: im not angeru, im working with him in the same project thats all

Fails after many hours? That sounds like a memory leak, in other words, you're creating bitmaps over and over without destroying any, or similar. Maybe you can get another program (such as top or the windows task manager) to display memory while your program runs, if the available memory constantly shrinks, that must be it. When it's run out of memory altogether it crashes.

They all watch too much MSNBC... they get ideas.

Which version of APEG do you have? Are you playing an MPEG or Ogg file? Given that you're not playing it in a loop, some variables may be overflowing somewhere.

Arthur Kalliokoski: I think that is the problem, but I can´t find where is the problem
Kitty Cat: apeg version: 1.0, and is playing a little mpeg

If the video's short, there's no way that loop should play for 2 to 3 hours. You're passing FALSE to the loop parameter, so it'll quit when it gets to the end.

Could you try using the newest version on the website (see my sig)? In that version, you should find a cbuild.c file. Replace it with this one:
http://svn.tomasu.org/index.cgi/cbuild/checkout/trunk/cbuild.c

I use FALSE in the loop parameter because the loop that calls the reproduce_video function (play_video in spanish) is in another function. The loop calls reproduce_video and another functions, When I see the freezes I remove the other functions and only keep reproduce_video and the programs freezes again.

I'll try with the newest version

PD: My english is very very very baaaaad :-[

PPD: I try and also freezes with the new version
