Changelog

v0.1 10/05/2005 Parsing of atoms; intial Tree printout; extraction of all "covr.data" atoms out to files

v0.2 11/10/2005 AtomicInfo.NextAtomNumber introduced to facilitate dynamic atom tree reorganization; CreateSparseAtom added

v0.5 11/22/2005 Writes artist properly of variable lengths properly into an iTMS m4p file properly (other files don't fare well due to the stsd atom non-standard nature); a number of code-uglifying workarounds were employed to get get that far;

v0.6 11/25/2005 Added genre string/numerical support, support for genre's dual-atom İgen/gnre nature, genre string->integer; bug fixes to APar_LocateAtomInsertionPoint when an atom is missing; APar_CreateSparseAtom for ordinary non-data atoms are now type -1 (which means they aren't of any interest to us besides length & name); implemnted the Integer data class; char4short; verified iTunes standard genres only go up to "Hard Rock"; added jpg/png artwork embedding into "covr" atoms; slight bugfix for APar_FindAtom (created spurious trailing "covr" atoms).

v0.6 GPL'ed at sourceforge.net

v0.65 11/25/2005 bugfixes to newly introduced bugs in APar_FindAtom; metaEnema to remove all metadata (safe even for m4p drm files); year implemented properly (tagtime moved onto non-standard 'tdtg' atom ala id3v2.4 - because I like that tag); added setting compilation "cpil" tag (an annoying 5byte tag); added advisory setting (maybe it'll give me a kick one cold winter day-do a "Get Info" in iTunes & in the main "Summary" tab view will be a new little icon next to artwork)

v0.7 11/26/2005 added a writeBack flag to for a less beta-like future; integrated NSImage resizing of artwork; environmental preferences for artwork modifications; build system mods for Mac-specific compiling;

v0.7.1 11/27/2005 modified parsing & writing to support Apple Lossless (alac) mp4 files. The lovely "alac.alac" non-standard atoms (parents & carry data) caused unplayable files to be written. Only QT ISMA files get screwed now (no idea about Nero)

v0.7.2 11/29/2005 creates iTunes-required meta.hdlr; all the tags now get spit back when reading them (--textdata); slight fix to how atoms are parsed; all known m4a files now tag properly: iTunes (m4a, m4b, chapterized, alac), Quicktime (ISMA & mpeg4 - change filename ext to .m4a to see art; all QT products require the meta.hdlr addition), faac, Helix Producer & Nero; slight change to how PrintDataAtoms called FindParentAtom; added tag time on "İed1" (edit date-might only really belong directly under udta); added "İurl" to hold url; fixes to APar_RemoveAtom; added cli ability to remove all artwork

v0.7.3 12/02/2005 handles stsd (and child) atoms better; modifies all stco offsets when needed (not just the first); new oddball iTMS video "drmi" atom handling; new "stik" atom support (sets iTunes GetInfo->options:Movie,TV Show, Music Video); writes iTMS video drm TV shows well now; diffs in a hex editor are moov atom length, and then into stco, so all is well

v0.7.4 12/03/2005 "desc", "tvnn", "tvsh", "tven" & "tves" setting

v0.7.5b 12/09/2005 forced 'mdat' into being childless (chapterized mpeg4 files have atoms scattered througout mdat, but they aren't children); fixed issues with ffmpeg created mpeg4 files (that have mdat as 2nd atom; moov & chilren as last atoms); moved ffmpeg mdat atoms around to end; better atom adding at the end; subbed getopt_long_only to getopt_long for pre-10.4 users; added progressbar

v0.7.5c 12/10/2005 funnguy0's linux patches (thanks so much for that)

v0.7.5d 12/11/2005 endian issues for x86 mostly resolved; x86: setting genre's segfaults; x86: stik doesn't get set in a multi-option command, but does as a single atom setting; Debian port added to binaries (compiled under debian-31r0a-i386 with g++4.02-2, libc6_2.3.5-8 & libstdc++6_4.0.2-2) - under VirtualPC - with the nano editor!

v0.7.5e 12/16/2005 ammends how atoms are added at the end of the hierarchy (notably this affects ffmpeg video files); writes "keyw", "catg", "pcst", "aART" atoms; read-only "purl" & "egid" added

v0.7.6 12/31/2005 ceased flawed null-termination (which was implemented more in my mind) of text 'data' atoms; UTF-8 output on Mac OS X & Linux - comment in DUSE_ICONV_CONVERSION in the build file to test it other platforms (maybe my win98Se isn't utf8 aware?); cygwin build accommodations; fix to the secondary "of" number for track/disk on non-PPC; implemented user-defined completely sanctioned 'uuid' atoms to hold.... anything (text only for now); "--tagtime", "--url" & "--information" now get set onto uuid atoms; allow creation of uuid atoms directly from the cli; cygwin-win98SE port added to binary releases; added '--freefree' to remove any&all 'free' atoms

v0.8 01/14/2006 switched over to uint8_t for former ADC_CPIL_TMPO & former ADC_Integer; added podcast stik setting & purl/egid; bugfixes to APar_RemoveAtom; bugfixes & optimizations to APar_FindAtom; changes to text output & set values for stik atom; increase in buffer size; limit non-uuid strings to 255bytes; fixed retreats in progress bar; added purd atom; support mdat.length=0 atom (length=1/64-bit isn't supported; I'll somehow cope with a < 4GB file); switch from long to uint32_t; better x86 bitshifting; added swtich to prevent moving mdat atoms (possible PSP requires mdat before moov); universal binary for Mac OS X release

v0.8.4 02/25/2006 fixed an imaging bug from preferences; fixed metaEnema screwing up the meta atom (APar_RemoveAtom bugfix to remove a direct_find atom); added --output, --overWrite; added --metaDump to dump ONLY metadata tags to a file; versioning for cvs builds; limited support for 64-bit mdat atoms (limited to a little less than a 32-bit atom; > 4GB); bugfixes to APar_RemoveAtom for removing uuid atoms or non-existing atoms & to delete all artwork, then add in 1 command ("--artwork REMOVE_ALL --artwork /path --artwork /path"); support 64-bit co64 atom; support MacOSX-style type/creator codes for tempfiles that end in ".mp4" (no need to change extn to ".m4v"/".m4a" anymore); moved purl/egid onto AtomicDataClass_UInteger (0x00 instead of 0x15) to mirror Apple's change on these tags; start incorporating Brian's Win32 fixes (if you malloc, memset is sure to follow; fopen); give the 'name' atom for '---' iTunes-internal tags for metadata printouts; allow --freefree remove 'free's up to a certain level (preserves iTunes padding); squash some memory leaks; change how CreateSparseAtom was matching atoms to accommodate EliminateAtom-ed atoms (facilitates the previous artwork amendments); exit on unsupported 'ftyp' file brands; anonymous 3rd party native win32 contributions; reworked APar_DetermineAtomLengths to accommodate proper tag setting with --mdatLock; parsing atoms under 'stsd' is no longer internally used - only for tree printing; reworked Mac OS X TYPE determination based on new stsd_codec structure member; revisit co64 offset calculations; start extracting track-level details (dates, language, encoder, channels); changed stco/co64 calculations to support non-muxed files; anonymous "Everyday is NOT like Sunday" contribution; changed unknown 0x15 flagged metadata atoms to hex printouts; move mdat only when moov precedes mdat; new flexible esds parsing

v0.8.8 05/21/2006 prevent libmp4v2 artwork from a hexdump; changed how short strings were set; win32 change for uuid atoms to avoid sprintf; skip parsing 'free' atoms; work around foobar2000 0.9 non-compliant tagging scheme & added cli switch to give 'tags' the GoLytely - aka '--foobar2000Enema'; ability to read/set completely separate 3gp tags subset (3GPP TS 26.444 version 6.4.0 Release 6 compliant & more like QuickTime-style tags); added libxml's utf8 & utf16 conversion functions; new windows (windows2000 & later) unicode (utf16) console output (literal utf8 bytes in win98 & earlier; memset standard means of initializing; simplified setting of arbitrary info uniformly onto parsedAtoms.AtomicData; win32 switch to CP_UTF8 codepage on redirected console output for better unicode output support; eliminate need for libiconv - use xml's utf8<->latin1 functions to supplant libiconv; properly display atoms like 'İnam' under Windows for trees & atom printouts; support setting unicode on Windows CP_UTF8; added 3GP keyword; fixed bug removing last 3GP asset to reset the length of 'udta'; added 'manualAtomRemove' for manually removing iTunes-style atoms; improved tracking of filesize/percentage when large free atoms impinge on % of new filesize; added 3GP location 'loci' (El Loco) atom - all known 3GP assets can now be set/viewed (except support for multiple same atoms of different languages); ->forced<- elimination of Nero tagging scheme (their foobar2000 inspired 'tags' atom) on 3GP files; prevent iTunes-style tags on 3GP files or 3GP assets on MPEG-4 files; fix offsets in fragmented files ("moof.traf.tfhd"); up MAX_ATOMS to 1024; Windows support for full utf16 (unicode) for cli args & filenames

v0.9.0 09/15/2006 new file scanning method based on an array of known atoms/KnownAtoms struct added to list the gamut of known atoms & their basic properties; better atom versioning & flags support; allow negatives in 3gp asset coordinates (switch to high-bit ascii for getopt_long for assets); fixed minor bug that crept in on non-Win systems in removing files; switch from moving mdat(s) to moving moov to reorder atoms; mellow_flow's genre fix; SLarew's utf16 fix for printing 3gp assets on Win32; reorder moov's child atoms so that udta is last (as per ISO spec recommendations) in moov; enable use of 'free' atom padding for rapid updating, pad with a (user-defined) default amount of padding with a complete file rewrite; switch remaining AtomicInfo variables over to pointers; add support for multiple same atoms with differing languages (like 3gp assets); more flexible 'stik' setting/retrieving & added Audiobook; genre bugfix (again!!); added ability to list std genres & stik strings; switch output for rtng's "Lyrics" to "Content"; list file brands; bugfix for removing some cli metadata; prevent optimizing on PSP mpeg-4 files (but allow dynamic updating, and don't add padding to psp files); new APar_FindAtom routine eliminating some loops; updated routine to find 'moov.udta.meta.hdlr' or iTunes-style tagging; simplified APar_RemoveAtom; 3gp assets differing in language are grouped now instead of being fifo; simplified printing of non-string iTunes-style tags; work around 3rd party bug affecting 'cprt' corruption; switch to fseeko to support files between 2.5GB & 4GB (and ancillary routines off of filesize like progress bar); fix co64 reduction offsets; prevent optimizing when just getting a tree or tags (screwed up track level details); bashfulbladder's booklet stik, only allow dynamic updating with --overWrite & new "AP -t +" routine to show padding & supplemental info; changing win32 filename to '-utf8.exe' forces raw utf8 input/output; win32 longhelp is converted to utf16 (for atom names); new shorthelp added as default help page; bugfix removing non-existing atoms; an actual change (removal/addition/change) of an atom is now required for any type of write action; fix channel listing for 'esds' without sec5 info; added ability to force image dimensions on MacOSX; revamped track level details; 255 byte limit for strings changed to 255 utf8 *character* limit; --stik Audiobook now changes file extension to '.m4b' (for Mac OS X, finder Type code is changed to 'M4B ' too); fix --3gp-year "" in APar_RemoveAtom; bugfix setting string lengths in 3gp keyword; added ability to add ISO 'cprt' copyright at movie or track level; implemented v5 sha1 namepsace/name uuids; fixed crash on finding any atom with full uuids (like psp files); more extensive type/profiles/levels in track level details; add support for embedding files on uuid atoms; switch to reading artwork directly into memory (as opposed to copying from a->b) when setting artwork; modified ExtractPixPrefs for leaks - defaults now to deleting temp pic files; skip sprintf for uuid binary strings ('qlts' is why) & switch to (less flexible) memcpy; accommodate iTunes 7.0 adding aprox. 2k of NULL bytes outside of any atom structure; add 'pgap' atom; defaults to duplicating the gapless padding at the end of file now (but can be optionally skipped); fixed clipping when setting unicode characters
