Subject: [PATCH] mpegvparse: Fix last start code position when input buffer is
 empty

When the input buffer is empty and we need more data to determine
whether or not to terminate the previous frame, the last start code
location needs to be set to 4 bytes before the the current position
(size of start_code is 32-bits)
