- Latest changes to the source
- ============================
- 1999-12-07 Released 0.89-stable:
- - Fixed the broken -rawbyteorder=[] switch. Thanks to
- Frans E. van Dorsselaer for reporting that bug.
- - The Windows and Linux executables of 0.88 were compressed
- using UPX. As a result the Windows version crashed instantly
- on some machines, so I'll skip UPX from now on (at least
- until they've found that bug).
- 1999-12-05 Release of 0.88! First stable release for a while. :)
- Changes done since 0.87.4-unstable:
- - Typecasted tablecontents in bladtab.c in order to produce
- less compiler warnings in Visual C++ 6.0.
- - Petteri Kamppuri corrected a bug that caused trouble if the
- input file didn't have a suffix, but a folder in the path
- did.
- - Changed homepage to bladeenc.mp3.no.
- Support for the config file under BeOS has still not been
- included and source is unlikely to compile correctly under
- OS/2, but I didn't want to wait anymore.
- 1999-11-23 Put 0.87.4-unstable online:
- - Long filenames finally working correctly in Windows. Thanks
- to Robert Schlabbach for getting me on the right track.
- - Petteri Kamppuri provided and requested some new changes that
- were needed for his MAC OS port.
- - Paul Martin discovered that I had screwed up the
- implementation of the -progress=[] switch and fixed it.
- - Vitor Sessak and Robert Schlabbach provided some minor fixes.
- - Paul Martin found that mono samples were not encoded
- correctly, fixed by Tord.
- - Paul Cantrell added defines for BeOS PowerPC.
- I was thinking back and forth about releasing this version as
- 0.88-stable, but I dedided to put this up first to give the
- people doing the non-windows/non-unix ports some time to add
- support for the config-file. I'm especially missing some code
- for the OS/2, BeOS and Amiga ports. Windows, UNIX and Mac OS
- code is allready in place.
- 1999-11-15 Put 0.87.3-unstable online:
- - The GCC compilation bug is finally fixed! Or maybe I should
- say patched since it seems to be GCC's fault. Anyway, many
- thanks to Marco Amrein for comming with the idea on how to
- find and patch the bug. Another sollution to the problem was
- provided by Vitor Sessak, but Marco's approach was more clean
- and straight forward.
- - Merged in some minor changes provided by Petteri Kamppuri and
- Paul Martin.
- Just the windows long filename bug to solve before I can
- release 0.88-stable.
- 1999-11-14 Made some changes that I put online as 0.87.2-unstable:
- - Fixed some compilation problems reported by Troy Engel and
- Robert Schlabbach. Should compile nicely without any warnings
- on most systems now.
- - Merged in some patches from Petteri Kamppuri which were
- needed for his upcomming MAC OS port of BladeEnc.
- - Added a PAUSE_25_LINES define for Windows and OS/2 to pause
- the info-output after 25 lines.
- - Added a switch (-progress=[0-8]) for changing the look of the
- progress indicator.
- - Progress indicator automatically switches to number 7 if we
- have a RAW file in the batch since BladeEnc doesn't know the
- filelength of RAW files (doesn't have a header and I don't
- want to check the filesize because that won't work on stdin,
- fifos(?) and files still being written).
- I have two very odd bugs that I would be happy if someone could
- help me with. One is related to Windows and the other is
- related to GCC (and possibly EGCS). More info can be found in
- TODO in the tar.gz archive. Unless something else pops up those
- are the only changes that needs to be done before 0.88-stable.
- 1999-11-11 Put 0.87-unstable online:
- - Went back to 0.83 since I couldn't fix the sound degradation
- in 0.84 and 0.85. Generates now the same quality as 0.82 and
- is just about 8% faster. :(
- - Merged in all the changes from 0.84 and 0.85 except the heavy
- optimisations from Matthias W鋍hter which somehow caused the
- quality degradation.
- - CONFIGURE, MAKE and MAKE INSTALL scripts for UNIX-systems
- thanks to KDevelop, which now is my main working environment.
- Only optimisation level 1 on all files though, since I can't
- set it individually in KDevelop and anything higher generates a
- mutated version of codec.c. when using egcs :(
- The following changes were made for 0.86 which was never
- released due to the quality bug, but they should all be
- correctly included in 0.87 as well.
- - Found and fixed a bug that often degraded the quality of the
- last frame in an mp3 and could cause the DLL to crash under
- certain circumstances.
- - Changed tabsize from 2 to 4 since that's more standard and
- reindented the code using a program called Artistic Style.
- - A lot of code clean-up and restructuring, but there's still
- loads to do. :(
- - Changed the way commandlines are handled internally to make
- it easier and cleaner to add support for configuration files
- and filelists.
- - Added suport for configuration-files on Windows and UNIX
- systems (bladeenc.cfg in same directory as bladeenc.exe on
- Windows systems and .bladeencrc in the home directory on
- UNIX systems). The contents in the cfg file is placed first
- on the commandline. Everything after a '#' is skipped.
- - Added support for priority settings on UNIX-systems. Default
- is NORMAL (not LOWEST as on Windows) priority and you can also
- use values -20 > 20.
- - Added a "-nocfg" switch for skipping any settings in the
- configuration file.
- - Addded support for RAW PCM input, including a number of
- switches for stating the frequency, number of channels etc of
- a RAW sample.
- - Added defines for HP/UX, submitted by Petter Reinholdtsen.
- - Replaced all longs with ints since long is 64-bits on Alpha.
- Thanks to Ben Slusky, Sadruddin Rejeb and the rest of you who
- told me about this.
- - Added defines for Linux Alpha, provided by Ben Slusky.
- - Added defines for MS-DOS, provided by Matt Craven.
- - Added code in main.c that will make it possible to change
- the look of the progress indicator as soon as I have added
- a commandline switch for it.
- 1999-08-07 Ok, back from the vacation I put 085-unstable online.
- Improvements since 0.84-unstable:
- - Matthias W鋍hter found a quality degrading bug in his
- optimisations for 0.84 and fixed it. He has also cleaned up
- and optimized l3psy.c and subs.c a bit further, which should
- do a few more percent.
- - Brad submitted a patch to make it compile nicely on OpenBSD.
- - Serg 'Ice' Tsyganenko found a bug in the code for reading the
- commandline, which under certain circumstances could confuse
- BladeEnc if one or more of the samples had ".mp3" in their body
- or specified path.
- I have some more patches to merge, but I'm going to England for
- a long business trip now (possibly two months), so they will have
- to wait until I come back... :(
- 1999-07-30 Put 084-unstable online. Improvements since 0.83-unstable:
- - Received and added some really heavy optimisations made by
- Matthias W鋍hter, resulting in a 28% speed increase on my
- machine! 8-) These optimisations have however broken the
- binary identicality with older versions (slight changes in
- precision (to the better) for a few routines early in the
- process) and I can therefore not guarantee that no quality
- affecting bug has slipped through. The quick investigations
- I've made of the code and output suggests that nothing bad
- has occured, but I would appreciate if some of you took the
- time to test it more closely (frequency analysis and listening
- tests mostly).
- - Fixed broken last frame in MP3-file using a sollution I know
- isn't the right one, but as far as I can see it should do the
- trick without any side effects. Thanks to Robert Schlabbach
- for bringing it to my attention over and over again... ;-)
- - Fixed what seemed to be a quality affecting bug, but later
- turned out to be harmless due to lucky circumstances. Thanks
- to Chris DeLise for discovering it.
- - Added defines for Linux PPC provided by Rich West.
- - Added patches for Ultrix & NetBSD provided by Simon Burge.
- - Made some minor optimisations, giving somewhere above 1%.
- Still have some of Roger Fujii's minor optimisations to include,
- but now I'm going on a short vacation (my first summer vacation
- in 3 years, hurray!) :-)
- 1999-07-23 Put the latest version online as 083-unstable. Improvements since
- 0.82:
- - Added a "-refresh"-switch to set the update rate of the progress
- indicator (in order to save CPU-time) and set the default
- refresh rate to 2 (half the previous one). This gave a speed
- increase of slightly more than 1% on my machine.
- - Added a define in SYSTEM.H called PRECISE_TIMER. This is a quite
- dirty hack by me to allow for more precise calculation of encoding
- time and is only meant as a tool when optimizing BladeEnc. It
- calculates and prints out encoding time with higher precision,
- but slows down the encoding process with about 2 seconds for
- each file. It's not extremely trustworthy either, but enough
- for my needs.
- - Started to merge in some optimizations provided by Roger Fujii,
- most notably a very clever replacement of the bladTabValue()
- function in loop.c which gave a speed increase of about 7% on
- my K6-2 350. Unfortunatelly this also makes a notably bigger
- executable since bladetab.c was changed and fleshed out.
- I still have some of his optimizations left to merge in,
- but they won't do more than about 2% together.
- - Probably one or two other minor changes which I've forgotten...
- 1999-07-23 Fixed a minor thing having to do with compilation on some
- machines. Put online as bladeenc-082-src-stable-2.tar.gz
- 1999-07-22 Fixed the embarassing skipping header bug in 0.80/0.81 by
- including a FIFO for the headers (by ISO called sideinfo) in
- formatbitstream2.h. Also got a few patches fixing minor bugs
- and compilation problems (WIN32_ALPHA and SCO OpenServer).
- Regarded this as stable and released it right away. I intend to
- concentrate on including the speedups I've been sent and release
- a new, hopefully much faster, version when that has been done.
- There will probably be an unstable branch of this since it includes
- changes to the FFT calculations that I want to be throughly tested
- for possible quality degradation before I release it to the masses.
- 1999-06-30 Loads of bugs in 0.80 fixed thanks to you guys out there.
- Released 0.81 as a bugfix release, so that is now the latest
- stable version. Also added a makefile, not exactly as good as
- a fully working Configure/Make/Make Install system, but I
- haven't gotten any of those some of you sent me working yet.
- I guess I just have to learn a little bit more about it first,
- until then you'll have to do with this simple,
- platform-dependent makefile.
- 1999-06-28 Version 0.80 stable released.
