NEWS / ANOUNCEMENTS
New version with importan gui controlls will be released shortly aswell as better optimization.
Made a new build because the old one behaved strangely and this one also
is 2x faster, so its about 18x realtime speed. So here is the
0.8.21 COPY NOW
and the usual source code with both gui/cli projects etc...
Also is fixed the effect where it wouldnt do anything when redoing a new conversion. It should
be faster too, 11x realtime on p3-750. So go for it peoples.
UPDATE: Mac Version of AC3DEC.
Ok finaly a new version, whats new? well like mpeg2avi PX3 0.1.4 , I am going the GUI, but unlike them, Im being one
step smarter/cooler and making it work in both GUI and CONSOLE mode, so if its run from an icon its in gui, if its
run with args or from dosprompt it acts like the old cli version. Har! Now why did I make it gui ? coz personaly
I was getting tired of typing ;-) So now even if your drunk and half asleep at 4am, you can just drag/drop the ac3
files on it and snooze for 13mins. So get it folks,
0.8.20 COPY NOW
and the usual source code with both gui/cli projects etc...
V3 of Divx2mp4 is done, just fixed
bugs, and updated some features. Go to Downloads area. Also
try my program XFILES for 'hidding' secret files
is ready... just a little feature to seek to TIMECODE. Also decodevob
1.5 is done, it will also optionaly write out
the VOB if you wish to remove an angle from a source VOB. So...
get your 0.8.19 COPY NOW.
8.18 is done now, a few goodies here, you can save/load codec settings,
the -44100 option is fixed and also its of higher quality when downsampling.
Also I have 'taken' the improvements of the official acedec0.6.x
on the linux side and put them (some) into this build, it should
be faster and give better quality. Also this should handle some
ac3 files which would make it crash. Oh and if you didnt notice
a little site redesign because the old look was getting boring,
(no frames too). So... get your 0.8.18
8.17 is out now, you can now automaticaly do PCM output without
that Chooser Box, so it can be scripted much happier now. Enjoy
here, 8.17 zip file. Also from now
on I am including decodevob part of the zip package because its
damn usefull and is much faster in combination by demuxing the ac3
first, then decoding the ac3. Demux can take 5mins, and ac3dec can
be upto 6.5 times real time speed.
Note to people who request 5.1 output in 3 wav files, yes it will
be done, patience please.
One Word, www.ac3dec.com is all you
need to remember.
On 24Mar I did upload a fixed ac3dec
which fixed the 1 channel problem, some wierd compiler effect. Now
the update, we have a new DECODEVOB which can decode vobs into m2v/ac3
files, now this special version will autohandle vobs that are encoded
in multi angles and this will just ignore the extra ones and only
keep angle 0. Note to hackers: the angle info is stored in the Navigation
Packets in the second area of the packet. I updated decodevob a
few hours after posting , fixed a bug where the last segment in
an angle segment was misoutputed, it sok now. As far as I can see.
AC3Dec fixes the status printouts
after 1gig of wav written, some other cosmetic fixes in status also.
But the biggest fix is DIVX2mp4, added some extra options to restore
your changes, or to do custom ID changes, and also a bug is fixed
New features for ac3dec, these include
better seeking without currupted audio and an insertMS option to
insert blank MS of audio into the output file, for those needing
to sync properly ;)
Also decodeVOB has been fixed/updated, better support for output
location which was part broken before and also better spanning from
1 vob to a second vob without missing data at all, and also fixed
the writing of the buffered IO which didnt flush the cache if it
finished half way into a block. Its all technical so basicly you
just gota know that its all ok now. And also you can specify the
buffer sizes to with -savesize and -preloadsize options to maxmize
you thruput. Having a brand new fast HD sure makes things fast.
Decode time for me of a 2:30hr ac3 took 14minutes. So download away
Ok, a small fix for ac3dec, just the
last buffer wasnt outputting nicely, and some other minor bits fixed
and you can now optionly decide the output buffer size too. AAC
code started, but not complete or working yet. So .814 ready now.
Decodevob has been updated with a
little better option, you can specify the output drive now, enjoy
Also I do have a future outline of plans to share with all.
1. incorporate use of the AAC encode DLL (MPEG-2 audio) to produce
mpeg-2 audio files. This looks easy since the encode is an easy
to use DLL. Also a possibility is to use the XING encoder too if
you wish to make mp1-layer2/layer3 audio files quicker than the
slow official implementation
2. A longer term plan is to make a version of ac3dec into a perfect
Decoder DLL just like the AAC is formated so that it then as a decoder
could be incorporated into mpeg2avi source, which btw at the same
time mpeg2avi could do a lot of fixes like the status info to be
more ac3dec like and handle those anoying crashes and ofcourse add
cooler options to it.
Heres an update of DecodeVOB
1.1 , supports a few extra commands and multi vob files spanning
and also output of multiple AC3 files at once, -audio 0 -audio 1,
you can put multiple of these in.
Not to mention ac3dec has gone to .8.13, just a few optimizations
in the heaftiest area (mantisa) and also more efficient buffered
output to make the HD happy.
Made a new program, DIVX2MP4, this will
re-convert an AVI/ASF back to MPEG4-v3 codec IDs from the DIVX one,
why? because we dont want stupid ASF files dependant on a codec
which is hard to find , we want an ASF made with the latest codec
and also be able to play back on any Windows OS too. Use it if you
like, if not, I dont care, but remember, all the DIVX codec is,
is the true mpeg4 codec , just the ID changed to make it work in
AVIs, (Why oh why is it called divx, tsk tsk tsk)
Been re-writing the VOB reader in
a seperate project for you all to try, get the program DecodeVOB
, ofcourse its in source and reads/decodes vob really fast and saves
out the m2v or ac3 file. Enjoy it. Its a hell smaller/easier to
read than BBDMUX stuff and faster. Feel free to incorporate it into
your own code, this should without too much trouble apear in ac3dec
Also ac3dec as a few tiny more features , thats all for now, enjoy
your transcoding. Dont forget, keep reading 2600,
Viva La Resistonce and freedom to all.
I think I fixed the high pitch sound,
blame optimization code in uncouple.c, it should be fine, testing
on one file I could hear an improvement.
Patience... been taking a break lately,
will make a major improvement soon in terms of speed + more cool
New beta code, in_ac3.dll is a plugin
for Winamp to play AC3 files, its more or less working still needs
some work for perfect use ,but its at least there.
-44100 from 48khz conversion seams to sound ok, so give that a try.
Thanks for all your emails, too busy to email
all individualy, but I addressed all bugs/problems , you can use
dvdsoft.de's forum also to address features. If you get wierd high
pitch audio effects, thats some core level maths stuff, I am talking
to the original author on possible fixes, but only some files seam
to do that, not all.
