One option is to setup a callback:

int my_callback()
{
   if(keypressed())
      return 1;

   stretch_blit(apeg_stream->bitmap, screen, 0, 0, apeg_stream->w, apeg_stream->h, 0, 0, 800, 600);
   return 0;
}

And pass NULL for the target bitmap for apeg_play_mpg. Another option would be to use the manual-advance functions:

APEG_STREAM *stream = apeg_open_stream(video);
while(apeg_advance_stream(stream, FALSE) == APEG_OK)
{
   if(stream->frame_updated > 0)
      stretch_blit(stream->bitmap, screen, 0, 0, stream->w, stream->h, 0, 0, 800, 600);
   else if(stream->frame_updated == 0)
      rest(1);
}
apeg_close_stream(stream);

To detect the end of the stream, you'll have to do the latter method and check apeg_advance_stream's return value for APEG_EOF (note that it may also return APEG_ERROR, which also means you should stop playing).
