1. Test bitstream
Small example bitstream (128x128 pixel dimensions) which employs all
picture_structure (top field, bottom field, frame), picture_coding_type
(I, P, and B), macroblock_type (forwards/backwards/interpolated,
intra/non-intra, coded/not-coded, quant/no quant, etc.), and
motion_type (field, frame, 16X8, dual prime) modes.
2. add trace printing for mpeg1 getblk routines.
3. modify getsys.c to parse program layer bitstreams (Systems)
with variable-length packets.
4. 24 bit X11 display
(borrow from Berkeley or find way for our code to use their interface)
5. MPEG-2 Transport layer systems streams parsing
6. Document IPR issue
provide CableLabs URL
how IPR relates to our disclaimer.
7. TIFF library support (YCbCr 4:4:4, 4:2:2, and 4:2:0 pictures)
[deferred]
10. IDCT rounding
As per IDCT corridgendum (Savatier, MPEG 95/XXX)
[done, but verified ?]
12. green dots in can
[ appears to be a display issue, probably related to convmat[]
error ]
19. move Dual_Prime calculation into picture_data()
20. motion vector calculation to include tappable stages to test
whether elements fall within [low:high] range.
21. Integrate verifier routines
22. Inter-layer verification routines
- check base and enhancement layers (e.g. SNR)
23. Spatial verification
- considering that no base layer is available.
24. SNR verification
[ done ]
25. DP verification
[ not done. No longer any bitstreams with Data Partitioning distributed
since DP is not part of any official Profile ]
26. merge all global bitsteam element variables into
common data structure (similar to layer_data). This is needed
for the verifier (whether or not headers in SNR and DP streams
are identical where needed to that of the base layer).
27. investigate why MS-DOS wants an extra % sign for filename patterns
when more than one filename pattern is used in the command line argument
28. convert -t (trace) flag into levels, merge with Verbose.
29. seek to a specified frame number (support for MCI-like functions)
30. document the "flash" VLC table decoding method in detail.
(namely how to map tables in Annex B to those in getvlc.h)
31. MPEG-2 program stream compatibility
(a few minor bits of difference in the system header ).
