Mike Melanson	160d679c07	Ministry of English Composition, reporting for duty (and the word is "skipped", not "skiped"; "skiped" would rhyme with "hyped") Originally committed as revision 4153 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
anonymous	8da75fb272	- 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 - trying to pass the proper coded status to block decoder patch by anonymous Originally committed as revision 3973 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
anonymous	7cc84d241b	- 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 - duplication of much code from msmpeg4.c; this code isn't yet used, but goes down as far as the block layer (mainly Transform Type stuff, the remains are wild editing without checking). Unusable yet, and lacks the AC decoding (but a step further in bitstream parsing) patch by anonymous Originally committed as revision 3931 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
anonymous	bf2bc926f0	- 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 obvious. patch by anonymous Originally committed as revision 3915 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
