Ministry of English Composition, reporting for duty (and the word is "skipped", not "skiped"; "skiped" would rhyme with "hyped")

- renaming the AC coding set variable names to more meaningful ones
- removed old MB decoding functions, and moved around macros to be used in
the previously unused code, which match better msmpeg4.c/whole MPV
framework
- cleaned (not yet functionnal, lots missing) DC prediction...

- samples from mplayer ftp in the "adv" profile seem to have profile=2,
which isn't the advanced one; and indeed, using adv. profile parser fails.
Using normal parser works, and that's what is done
- attempt at taking care of stride for NORM2 bitplane decoding...

- a lot less overflows when decoding frames
- no more error with norm6 codes
- almost skipped frames (~110 bits) are not overflowed
However:
- there are very few bits left in those frames, so I wonder if enough MB
data is actually left
- NORM6/DIFF6 (4/5) bitplanes are a lot more present, which I don't find...

100000l (typos in the #define for selecting the NORM6 method -> wasnt compiled, after fixing typos new method doesnt even compile -> swicth back to old until its fixed)

- add another way to decode norm6 VLC; modify VLC_NORM6_METH0D define in
vc9data.h to select the behaviour
- modified decode_b_picture_primary_header so that
decode_bi_picture_header is no more required

Fixes:
- modifications for some more using of MpegEncContext...

0d33db8a 01/30/2005 04:34 PM anonymous

In that patch:
- avctx and gb elements were removed from VC9Context, hence a larger diff
- some code was added to h263dec.c regarding CODEC_ID_WMV3 (should apply to CODEC_ID_VC9 too)
- VLC tables and other related tables were made global whenever this seemed necessary; appropriate changes were therefore made to other parts of the code using those tables...

use dc tables from msmpeg4 instead of duplicating them patch by anonymous

check norm6 vlc validity as there are some bit sequences which dont corespond to any codeword, the other vlc tables all seem to be huffman tables though

Fixes:
- i/p/b_decode_mbs functions now checks the proper values (from
bitplane). I didn't find it very clear, but it seems "raw" = "to read at
the MB layer". I used a structure, but we could spare that indirection and
add a flag in the VC9Context for each array....

norm-6 / diff-6 support (untested, parts of it just guessed as the spec is unclear)

fixing many bugs in bitplane_decoding()
spliting row/colskip cases into their own functions as these will be needed for NORM/DIFF-6
