=====
3
Pre-release caveats:
4
 
5
  - has only been tested with gcc.  (I'm not sure we will even bother
6
    with acc, or cc in the future).
7
 
8
  - I'm fully aware of the warnings received by -Wall
9
 
10
  - Verifier still not integrated (due to complexity), although
11
    experimental vbv_delay code included in verify.c

===============================================================
17
Frame buffer substitution edition of decoder.
18
 
19
Restrictions:
20
 - temporal_reference in bitstream must be correct.
21
 
22
 - substitute pictures must have pixel (luminance samples) width
23
   and height equal to coded_picture_width (mb_width*16) and
24
   coded_picture_height (mb_height*16) rather than horizontal_size
25
   and vertical_size, respectively.
26
 
27
 - all input pictures must be interleaved into a frame.
28
 
29
 - frame count (index) is based on absolute display frame order with
30
   no repeated (3:2 pulldown) fields or frames.
31
 
32
--------------------------------------------------------
33
Notes:
34
 
35
 - command line arguements in this edition differ from verifier
36
   style.  This decoder's arguments are the same as the
37
   public distribution's (July 4, 1994) code .
38
 
39
   please note that this code, with frame buffer substitution, when it
40
   is released will use the verifier style of arguments.
41
 
42
 - Carsten's updated spatial scalability decoder routines have been
43
   incorperated.
