        /* For psnr computation, we need to read the correct input frame and

         * that the frame number of recon is monotonically increasing. There
         * may be gaps in the recon if any pre or post enc skip happens. There are
         * 3 senarios
         *  1) A frame is encoded -> returns the pic type
         *  2) A frame is not encoded -> Encoder is waiting, the frame may get
         *     encoded later
         *  3) A frame is not encoded -> A post enc or pre enc skip happend. The
         *     frame is not going to be encoded
         *
         *     The 1st and 2nd scenarios are easy, since we just needs to increment
         *     recon cnt whenever we get a valid recon. This cnt can we used to
         *     sync the recon and input
         *     3rd scenario in conjuction with 2nd will pose problems. Even if
         *     the returning frame is NA, we donot know we should increment the
         *     recon cnt or not becasue it can be case 2 or case 3.
         *
         *  Solutions:
         *  -------------------------
         *   One way to over come this will be to return more information as of
         *   the frame type. We can send if a frame was skipped as a part of the
         *   return frame type.
         *   This will not work. Since the output and recon are not in sync, we
         *   cannot use the current output frame type to determine if a recon
         *   is present currently or not. We need some other way to acheive this.
         *
         *   Other way to do this which is cleaner and maintains the seperation
         *   between recon and the ouptut is to set the width [& height] of output recon
         *   buffer to be zero. Hence we will in effect be saying :"look there
         *   is a recon, but due to frame not being encoded it is having a width 0".
         *   To be more clear we need to make height also to be zero.
         *
         *   But are we using these variables for allocating and deallocating
         *   the buffers some where ? No we are not. The buffer gets re-init
         *   at every encode call
         *
         *   Fixes
         *   ------------------------
         *   Currently the recon buff width and height are set in the encoder.
         *   This will not work now because since recon and input are not
         *   in sync. Hence a recon buff sent at time stamp x will get used to
         *   fill recon of input at time stamp y (x > y). If we reduced the
         *   frame dimensions in between, the recon buffer will not have enough
         *   space. Hence we need to set the with and height appropriatley inside
         *   lib itself.
