	You hit against our printf() paranoia measure. 2 ways around it:

1) Official solution: use av_log() instead of printf():
   printf ("Hey: %d\n", 610);
   av_log (NULL, AV_LOG_INFO, "Hey: %d\n", 610);

2) Unofficial hack: "#undef printf" near the top of the source file (but 
after lavc #includes) in which you wish to enable printf(). Just don't 
submit code back to us in that form; use the official solution.

	Hope this helps...
