BSN=BeSweet+Nero

[DSPguru]

ok, i had written something.

this is a very basic ac3->mp4 transcoder.
it is based on "nencode", but uses BeSweet.dll instead of nero's input plugins.

source-code is public and anyone with some basic c knowledge, can extend it to take advantage of all BeSweet's features (mpa input, two-pass, etc'..). more info here.


i really hope that someone will actually take the code and push it forward, this time. must admit that until today, lots of people had asked for my tools' source-codes but none had done anything with stuff i did publish.

enjoy,
Dg.



edit : BSN.exe is obsolete, and now integrated in BeSweet as bsn.dll.

[OBcecado]

Hi, I downloaded the app you've wrote, but i can't find out how to define bitrate to be used, it says something about presets or something, but i can't figure it out.
Sorry for this lame question.



Thanks in advance.

Has anyone tried this great tool. I can't get it to work. I have copied 'aac.dll', 'aacenc32.dll' and 'NeroIPP.dll' to BSN dir and I'm using one of DSPguru's commandline examples from readme.txt file (I have tried both actually). It starts fine, I can choose settings for Nero's encoder and BeSweet starts finding maximum gain but once the maximum gain has been found it just crashes. Microsoft's error report says that the crash
occured because of aacenc32.dll but I don't know what's causing it.

Can anyone else please test this and report the results?

DSPguru, thank you for all your work, it is greatly appreciated.

[DSPguru]

currently, two-pass isn't implemented..

you can set a static gain value like 10db or the value it found in the first pass before crashing..

Thanks DSP guru,

This is the S/W i was looking for.I tried it over small ac3s-Working perfectly....no crashes...no problem.I have got a doubt:which AAC.dll is to be put in this,From Nero 60011 or later?(I have already put 60015 plugin:some confusion on reading the other thread on neroac3 plugin. )Thanks again.

This is really weird. I'm using a very simple commandline, as simple as this:

bsn.exe -core( -input test.ac3 -output test.mp4 -2ch )

But it always tries to find max gain and of course after that it just crashes. Here is how it looks before the crash:

As you can see it writes 'Input: ac3input' even though the input file name is 'test.ac3'. I have also tried with setting manual gain with the -ota( -g 4.7db ) switch but again, it tries to find max gain.

I don't know what it is but it's obviously something on my side as Tuning's post proves that it's definitely working.

DSPguru, any thoughts on this?

Just use the ones from 6.0.0.15 release and later. They have the standard WAV ordering input which is what BeSweet outputs.

@mfluder,
The above post was based on the 5.1AAC creation and i also tried stereo AAC.The lenght of ac3 was only 1 min 32seconds(both case).Created a fine file.
Using this line bsn.exe -core( -input d:\aurora.ac3 -output d:\test.mp4 -2ch ) -ssrc( --rate 44100 )

No crash and completed encoding the entire length.
I'm currently using AAC.dll from nero 60019.
Thanks mfluder.

Edit: i'm going to try a huge ac3 of 3hr42min now.Results will be posted later.bye

5.1
I could trancode the ac3 of length 3:42:52 in to AAC.The bitrate chosen was constant HE-AAC profile at 128kbps.The resulted file had a size of 224MB instead of 204MB as indicated by GK(don't know if Mutichannel makes larger file).

The another thing i could find problem is the playing in winamp.This mp4 file playes very slowly than regularly encoded files[Correct channel order in winamp..Ok].

After installing the 3ivx codec and CoreAAC,every media player crashed and auromatically quit when trying to play.Then I tried the
Older AAC.dll(60011) and encoded a part of the same ac3 at same settings.The resulted file could be played in winamp,media players and i can assure ,without a single problem.But the channel order of second file is wrong.

2.0
The same 'short' ac3 file was again encoded by using the two AAC.dlls(60011&60019@128kbps HE-AAC:

So is there anyway in which correct channel ordering can be made and everybody could use the old (60011)AAC.dll ?DSPGuru??

Tuning

[DSPguru]

channel mapping problem and this playback issue had already been discussed in here.
to change channel ordering, use the switch "-azid( -oc,l,r,sl,sr,lfe )"


anyway,
i had released BeSweet v1.5b22 with bsn.dll .

commandlines are :
BeSweet -core( ) -shibatch( ) -boost( ) -azid( ).... -bsn( -2ch/-6chold/-6chnew )

[bond]

any plans to support quicktime too? there is also a quicktime commandline wrapper available here

no

btw are there any plans to incorporate the bsn options into the besweet gui

The new BeSweet pack with BSN proved to be the easiest way of 5.1AAC encoding.

The incompatibility of newer AAC.dll on playback forced to me to use the older version in Nero 60011.Using this & the altered commandline generated using GUI helped me to create(Finally..)5.1 HE/LC streams working on every media player which had installation of 3ivX Codec & CoreAAC filter.

For Creating 5.1 HE/LC AAC :

BeSweet -core( -input "d:\ac3test.ac3" -output d:\outtest.mp4" -6chaiff -logfilea "d:\BeSweet.log" ) -azid(-oc,l,r,sl,sr,lfe ) -ota( -G 1 ) -ssrc( --rate 44100 )-boost( /b3=5 /l=0.95 ) -bsn( -6chold )



For Creating 2.0 HE/LC AAC :

BeSweet.exe -core( -input "d:\Lagaan.ac3" -output "d:\Lagaan.mp4" -logfilea "d:\BeSweet.log" ) -azid( -z1 -b1 ) -ota( -G 1 ) -boost( /b3=5 /l=0.95 ) -bsn( -2ch )

Following information was obtained during this test:
The center channel found to be louder,by above mentioned 5.1AAC method.Is there anything wrong?


HE-AAC is only enabled :
in CBR mode:Below or equal to 80kbps.
in VBR mode:below or equal to streaming:medium Quality.

In all other conditions,even if u try to set HE-AAC, LC-AAC is used.

The 5.1mp4 file created by this process plays in winamp2.92 with incorrect channel mapping even when used with latest AAC plugin from Rarewares.
This file plays without problem in most of media players,including WMP6.4,MPC6.4.6.5...

Encoding in BeSweet is slower for 5.1 than 2.0.
The MKV file created using mkvmerge0.7.0 woked well in media players.
Please correct me if anything stated here was found wrong.

[Gaia]

You're using very old version of Winamp2 aac plugin.


Latest is always here http://www.hydrogenaudio.org/index.p...428&st=100&hl=

[Tuning]

I followed ur link and downloaded two filters,in_mp4 & CoreAACDS.The filters responded differently.The 5.1mp4 played with correct channel order in CoreAACDS[I can confirm this as i'm using the ac3test file],while it played in winamp with center as right and right as SR and some more changes.Therefore this confirms the channel mapping is not corrected in this release.

that's very good news!
btw, for 6ch, i would suggest the following commandline :

BeSweet -core( -input "d:\ac3test.ac3" -output "d:\outtest.mp4" -logfilea "d:\BeSweet.log" ) -azid( --maximize -c normal ) -bsn( -6chold )

and the "-ssrc( --rate 44100 )" is only optional..
afaik, all multichannel soundcards can playback 48khz streams, so the only motivation to downsample to 44.1khz is if the nero encoder is better tuned for 44.1khz streams than for 48khz. (better ask Ivan)
---
same idea for 2ch:

BeSweet.exe -core( -input "d:\Lagaan.ac3" -output "d:\Lagaan.mp4" -logfilea "d:\BeSweet.log" ) -azid( --maximize -c normal ) -bsn( -2ch )

Following information was obtained during this test:
The center channel found to be louder,by above mentioned 5.1AAC method.Is there anything wrong?

nothing i know of..

Encoding in BeSweet is slower for 5.1 than 2.0.

that's reasonable.

[Tuning]

Thanks again,

I will change the line as suggested by u from the very next rip.

BTW,The greater loudness of center channel is a guess or assumption as I have only 4.1 Card.The sound "Center" is heared to be louder than "Left" or "Right" through front speakers.
