MAREO 2.0 Development

Hi, i have started to develop MAREO 2.0 ... I'm planing on using free pascal's multithreaded routines to run multiple encoders at the same time ... so the question is ... is there any other option that the community sees it is needed?

EDIT:
LIST OF  NOT LOCKING ENCODERS
lame.exe
oggenc2.exe (OggEnc v2.3 (libvorbis Post 1.0.1 CVS))

LIST OF  LOCKING ENCODERS

another thing i would need to know is for each used encoder, does it "opens" the wav in exclusive mode? so if, for example, i try to run flac on the same source wav, at the same time, would it generate a protection error? i would try lame.exe, but i don't know/have all the used encoders

I have no experience with MAREO or with using commandline encoders with EAC, so just ignore me if this is a stupid question, but why do you need a source wav? I have written an output plugin for Winamp that can use commandline encoders and I simply pass the data through a pipe (I can even retrieve the output data through a pipe again), this should work flawlessly for multiple encoders too.

Because EAC writes a wav file. Does not pipe it.
Or perhaps I am totally clueless.

You are absolutely right (I just checked), I hadn't thought of that option yet, EAC is probably very worried about being able to store the PCM data fast enough.

exactly, besides, mareo can work with ANY ripper, cdex, dbpoweramp, audiograbber, etc.

I use MAREO with EAC to encode to OptimFROG DualStream.  EAC renames the .ofs file but not the .ofs correction file.  So to get round this I have a second line in MAREO that doesn't do any encoding but does rename the file:

Code: [Select]
ofc NONE NONE donothing.exe


In order for this to work I have had to create a donothing.exe program in Delphi which is a console program that literally does nothing.

Code: [Select]
program donothing;
{$APPTYPE CONSOLE}
begin
end.


This is a bit messy.  So would it be possible to enhance MAREO so it can take NONE as the CommandToRunWithParameters (ie. the fourth item in an action line)?

Code: [Select]
ofc NONE NONE NONE


I would think this would be useful with any hybrid encoder that generates two output files, although I haven't used any other.

EDIT: Or if there is already a simpler way to do this I have overlooked, please let me know.

Another request:

it would be great if MAREO would take an additional command line parameter telling it which ini file to use.  So instead of having to edit mareo.ini and comment out lines to change encoder, I can create different ini files for each combination of encoder I use and then simply type the required ini file in the EAC "Additional command line options".

i have also been asked to make mareo "create" a WAV file, so if the CommandToRunWithParameters is WAVNONE  mareo would only rename, and not encode.

Excellent.  Thank you.  (and for the ini file parameter)

If you have already implemented NONE as a CommandToRunWithParameters value, would WAVNONE really also be necessary?  Surely the same can be acheived using

Code: [Select]
wav <2ndParam> <3rdParam> NONE


Or have I misunderstood?

you are correct ... they are both related to each other ... so maybe the 2nd is not needed ... i would look at it for sure.

Hi, i have started to develop MAREO 2.0 ... i have already moved it to Lazarus/Free Pascal so anyone can compile it (and even move it to LINUX) since Borland no longer offers a free version of Delphi. I'm planing on using free pascal's multithreaded routines to run multiple encoders at the same time ... so the question is ... is there any other option that the community sees it is needed?

Did you consider C#?  It's available for both Windows and Linux (the compiler comes free with Windows, just not the IDE) and C# at least has a future.

frepascal is GPL, so it has a future for sure ...

ok guys, i finally made MAREO 2.0 compile under lazarus ... it took me more time than i thought  .... anyway, i haven't goot feedback from users of other encoders than lame.exe on wheter the encoders lock or not the WAV files ... i need to know it, cause if  that is the case, mareo would need to ccpy the wav, once for each encoder threat ... so, any feedback?

I just tried oggenc2.exe (OggEnc v2.3 (libvorbis Post 1.0.1 CVS)) and it seems it doesn't lock it (at least not for reading), as I could play the wav with winamp while encoding, CoolEdit also didn't mind opening it.
As for copying the wav, that does sound awfully slow, I understand now why EAC doesn't pipe the PCM data to the encoder directly, but I see no reason why you couldn't pipe the data to the encoders (if some encoders do lock that is). That would probably be quite a lot faster than first having to copy the WAV file.

Multithreading? Awesome, this should speed things up with my hyperthreaded P4! Anyway, I use MAREO to do LAME and FLAC and have been recommending it on Ars Technica message boards for some time to others looking to do the same. One thing that I have done in the past but am no longer doing is WaveGaining after a FLAC is made but before an MP3 is made so that the MP3s are normalized but the FLACs are the original source. This required me to have MAREO "leave" the WAV but also run a delete batch file I made on the WAV file (so MAREO thought it was leaving the WAV alone but in reality it was deleting it at the end.) Hopefully that makes sense. That's a feature that would be nice to have in the finished version of MAREO 2.0. I'm willing to help beta test (Windows XP, EAC, LAME, FLAC.) Keep up the good work!

hi rh, thanks for your help ... what is exactly the problem with wavegain ... i don't quite get it :| ... i would be posting as soon as i have a working prototype of M2

you are right ... i would do it in C# then ... so users then have to download a 15 MB "runtime" ...  ... if it does what i need, why should i ditch free pascal? have you bothered to go to the lazarus site?

Actually they don't have to download a 15 MB runtime, although that might be simplest.  Do you know about mono the open source C# initiative?

But, your point is good.  Then why not C++?  Or C?  Or any language that people could hope to use on a job, someday?  Working in Pascal is about as practical as working in FORTRAN.  (And yes, I know that a lot of work is done in FORTRAN on supercomputers....)

You wouldn't have all that much trouble learning C/C++.  Back when Pascal was first beginning to dry up and all the Pascal programmers were converting to C, it was very popular to define a bunch of manifest constants so that C code looked like Pascal.  You know:

#define BEGIN {
#define END }

etc.

why should i change? would it be faster in C/C++? would it do more things that it would do with FP?

besides, the beautifull thing about all this GPL thing is, you can see the code, and translate it to C/C++ ... it appears you are very good with them ... anyway, i wanted to know what users wanted from "MAREO 2.0" ... i think the ones using 1x don't care it was writen in Delphi ... they care that it works for them ... so any more *relevant* info?

PS: by the way, did you ever tried Delphi? ... if you did, and liked it, let me tell you, it is pascal ... i just moved to FP, cause this is a very basic, command line tool, and i win nothing by using delphi ... finally, you can check here:, but just in case:

Don't misunderstand me, I was just curious.  Some developers I highly respect use Delphi, but it seemed strange that if one was going to abandon Delphi why one would stick with Pascal.  I mean, the reason people use Delphi (as far as I can tell) is because it is a great development environment, not because it is Pascal.

As far as "would it be faster in C/C++," well, I'm not all that big a proponent of making speed my primary yardstick of program goodness, but in this case the answer is "it could be," in the sense that you can get much closer to the metal with C.  I mean, I'd bet a considerable sum that Delphi isn't written in Delphi...

The reason for my original suggestion of C# was that .NET is a very supportive development environment.  I've noticed that my productivity has increased considerably since I began doing most of my work in C#.  The one thing .NET isn't, though, is fast at execution.  Fast at development, yes, fast at runtime, no.

And I'm too much of a smart-aleck to let this go by:
