| 1085 | pj | 1 | 1. Test bitstream |
| 2 | Small example bitstream (128x128 pixel dimensions) which employs all |
||
| 3 | picture_structure (top field, bottom field, frame), picture_coding_type |
||
| 4 | (I, P, and B), macroblock_type (forwards/backwards/interpolated, |
||
| 5 | intra/non-intra, coded/not-coded, quant/no quant, etc.), and |
||
| 6 | motion_type (field, frame, 16X8, dual prime) modes. |
||
| 7 | |||
| 8 | 2. add trace printing for mpeg1 getblk routines. |
||
| 9 | |||
| 10 | 3. modify getsys.c to parse program layer bitstreams (Systems) |
||
| 11 | with variable-length packets. |
||
| 12 | |||
| 13 | 4. 24 bit X11 display |
||
| 14 | (borrow from Berkeley or find way for our code to use their interface) |
||
| 15 | |||
| 16 | 5. MPEG-2 Transport layer systems streams parsing |
||
| 17 | |||
| 18 | 6. Document IPR issue |
||
| 19 | |||
| 20 | provide CableLabs URL |
||
| 21 | how IPR relates to our disclaimer. |
||
| 22 | |||
| 23 | 7. TIFF library support (YCbCr 4:4:4, 4:2:2, and 4:2:0 pictures) |
||
| 24 | [deferred] |
||
| 25 | |||
| 26 | 10. IDCT rounding |
||
| 27 | As per IDCT corridgendum (Savatier, MPEG 95/XXX) |
||
| 28 | [done, but verified ?] |
||
| 29 | |||
| 30 | |||
| 31 | 12. green dots in can |
||
| 32 | [ appears to be a display issue, probably related to convmat[] |
||
| 33 | error ] |
||
| 34 | |||
| 35 | 19. move Dual_Prime calculation into picture_data() |
||
| 36 | |||
| 37 | 20. motion vector calculation to include tappable stages to test |
||
| 38 | whether elements fall within [low:high] range. |
||
| 39 | |||
| 40 | 21. Integrate verifier routines |
||
| 41 | |||
| 42 | 22. Inter-layer verification routines |
||
| 43 | - check base and enhancement layers (e.g. SNR) |
||
| 44 | |||
| 45 | 23. Spatial verification |
||
| 46 | - considering that no base layer is available. |
||
| 47 | |||
| 48 | 24. SNR verification |
||
| 49 | [ done ] |
||
| 50 | |||
| 51 | 25. DP verification |
||
| 52 | [ not done. No longer any bitstreams with Data Partitioning distributed |
||
| 53 | since DP is not part of any official Profile ] |
||
| 54 | |||
| 55 | 26. merge all global bitsteam element variables into |
||
| 56 | common data structure (similar to layer_data). This is needed |
||
| 57 | for the verifier (whether or not headers in SNR and DP streams |
||
| 58 | are identical where needed to that of the base layer). |
||
| 59 | |||
| 60 | 27. investigate why MS-DOS wants an extra % sign for filename patterns |
||
| 61 | when more than one filename pattern is used in the command line argument |
||
| 62 | |||
| 63 | 28. convert -t (trace) flag into levels, merge with Verbose. |
||
| 64 | |||
| 65 | 29. seek to a specified frame number (support for MCI-like functions) |
||
| 66 | |||
| 67 | 30. document the "flash" VLC table decoding method in detail. |
||
| 68 | (namely how to map tables in Annex B to those in getvlc.h) |
||
| 69 | |||
| 70 | 31. MPEG-2 program stream compatibility |
||
| 71 | (a few minor bits of difference in the system header ). |
||
