int CalculateFrameNumber ( ImageParameters *  p_img  ) 

Calculates the absolute frame number in the source file out of various variables in img-> and params->.

Returns:
frame number in the file to be read
side effects
global variable frame_no updated -- dunno, for what this one is necessary

static void code_a_picture ( Picture *  pic  )  [static]

Encodes a picture.

This is the main picture coding loop.. It is called by all this frame and field coding stuff after the img-> elements have been set up. Not sure whether it is useful for MB-adaptive frame/field coding

Allocates forced INTRA MBs (even for fields!)
