Can someone explain to me how to tag my files trancoding from FLAC (with full tags) to AAC (m4a), using the "Nero AAC" in Media Coder? My file encode's correctly, but the tag info is blank in my m4a files. I have no problems (full Tags) when I use FAAC and iTunesEncode. Thanks.

Files produced with Nero AAC encoder aren't tagged, as I haven't seen any tagging related interface of Nero AAC Encoder. In this case, they need manually tagged afterward, but currently tagging m4a files is not implemented.

EDIT: I found a MP4 tagger [a href="http://www.hydrogenaudio.org/forums/index.php?showtopic=12075]here[/url]. I will try to merge it into MediaCoder.

Introduction
MediaCoder is an open source audio/video batch transcoder, putting together many excellent audio/video softwares from the open source community into one friendly GUI. On video side, MEncoder is used as back-end, which provides support for nearly all known video compression and container formats as well as rich and useful video filtering features (e.g. post-processing, 3D de-noise). On audio side, MPlayer and Winamp input plugins used as decoders, various encoders integrated, MediaCoder can simply batch transcode among any known audio formats, with tags transferred, file names generated, and even performing audio filtering (e.g. resample, normalize) on the fly.

Supported source formats: MP3 (Lame), OGG/OGM (Vorbis), AAC, MusePack, FLAC, WavPack, APE, WAV, CUE sheet, WMA/WMV/ASF, RealMedia (rmvb), AVI, MPEG1/2 (MPG/DAT/VOB), QuickTime/MOV, MP4, Matroska and any other formats supported by Winamp input plugins
Supported target audio formats: [Lossy] MP3, Ogg/Vorbis, LC-AAC (iTunes, Nero AAC Encoder, FAAC), HE-AAC/Parametric Stereo (CT, Helix),  MusePack, WMA [Lossless] FLAC, WavPack, APE, WMA Lossless, WAV
Supported target video formats: H.264, Xvid, DivX 4/5, MPEG1/2, MS-MPEG4, H.263 etc.
Supported target container formats: AVI, MPEG, Matroska, MP4 (audio only)

Thanks for the link to the source code.

I've now fixed everything that was stopping me from using this great app.

I've also added in another stage post-AACPLUSv2 encoding where the AAC stream is now converted from MPEG2-AAC into MPEG4-AAC using Nic's AACPATCH too. Got the naming to work too.

Lurveleee!!

Now I just wish this was written in .Net, using C is like going back a 1000 years and also growing a ponytail and a beard! lol j/k

Theres also a number of areas in the code where the shell calls are not managed well, this can cause the application to stop responding, when a junk file is thrown at it for instance.

Off to bed now, been up all night!

hey optimus!

thankyou for making such a fantastic tool. it has made my life a thousand times easier. i cant thank you enough!

now that the sucking up is complete, i have a couple of questions for you. MUAHAHAHAHA

anwyays, why is it that when i try to re-encode an mp3 file that is say 100mb in size and about 70mins long (dj mix) to an ogg file, it stops encoding at approximately 40% of the file?? this only happens using the winamp input plugins as the source. everything is fine using mplayer as the source. why im asking this is because when i first used mediacoder  when it was in 0.2.8 revision, everything was fine with the winamp input plugins.
have u changed the in_mp3.dll or whatever? it doesnt seem to be working snmoothly anymore.
ive installed the latest winamp v5.112 so ill maybe just copy the in.dll file to mediacoder and see whetgher that corrects the problem...but it seems as though the input plugins of past revisions are more stable.

my last question is this. what are the chances of you implementing support for sonys ATRAC3plus encoder/decoder? personally i think this would be and absolutely genius move on your part!

i really dont know enough about .dll files etc to tell you exaclty what files you would need to even begin to try and implement the ATRAC3plus support, so if you would have the time and patience of figuring that part out as im not competent, it would be much apprecitated!

oh, and the oggenc.exe that you use for mediacoder is a slowe, non SS2 enhanced version. there is an oggenc made by Lancer that is twice as fast as the regular oggenc and on par/faster than aac2plus encoder.

keep up the great work bud!

I just tried TG.exe and it works perfectly with the MP4 container too!

* Use the existing TAG for MP3's etc and TG for MP4 sources and MP4 containers.

* Can you remove the -SBR option you have hardcoded for MP4Box commandline? And add the following switches as checkboxes in the MP4Box settings node:

-mpeg4
-packed
-hint
-ocr
-rap
-ts
-size
-idx
-isma
-new
-lang xxx       (where xxx = language such as ENG)
-sbr
-keepsys


Put ocr/rap/ts/size/idx as child nodes for hint as they are configuration options for hint.

Also add a list of languages as a drop down 3 letter abreviated list, I believe there is a MPEG4 standard list somewhere over on MPEG4IP docs.

Dont forget to change destination filename extenstion to .MP4 or .M4A on MP4Box destination filename. Put the option in the MP4 container settings to allow users to select between different output filename extensions (just makes life easier for iPOD users too)

Cant wait for the next version!!!!

What's going on, Optimus.You release 0.33 version of Mediacoder.What is new.
[a href="index.php?act=findpost&pid=342699"][{POST_SNAPBACK}][/a]

Hi Optimus, good to see you're back on the case, MediaCoder will be a legend as time goes by!

I would love to co-work on this project, but I'm totally uncomfortable with basic C. Why not do a poll? supporting both Linux and Windows will limit your abilities to really take advantage of Windows frameworks, plus a few of the dependancies of the project are already windows only, so I reckon you should keep it windows? thats where a sizeable chunk of the userbase is anyway.

I will be extremely interested in co-working on a .Net C# application, it will make things very interesting, but at the same time you can still utilize C for libraries where you want total performance and control, but making the GUI .Net will make coding easier and also allow us to implement tonnes of feature fairly easily.

Have a coffee and think about it... and I suppose if people want to branch off a version to work on Linux, they can still use Mono anyway...

Talking about C#, I have switched to a new company, where C# is the main development tool. Though I don't know much about C# before, I will be surely using it in future.   And some time ago, I was planning to design a wizard to make MediaCoder easier to use for people other than advanced users. I was thinking of using a more effiecient GUI development tool other than the mechanism I am currently using and .Net is one choice. So I think it might be a good idea to firstly development part of MediaCoder in C#/.Net (the wizard maybe). This takes serveral factors in to consideration, one is my limited experience with C#/.Net and that I need time to get used to the new tool, the second is to keep the existing work (rebuilding everything from ground will take much more efforts). The third, might not be so important, is that I am still in favor of languages that can be compiled into machine code directly.

How about this, if you can start by making the existing C/C++ core code into modular libraries but continue to use the existing GUI code, I can then work with your libraries alongside and develop a .Net gui, that way it doesnt impact on Mediacoder directly and we effectively seperate the application layer from the interface layer (gui). I will develop the GUI to also be modular so that others can create plugins to utilise the GUI in applications such as dbPowerAMP, EAC etc etc.



So put all your functions into actual DLL with interfaces, and then re-work your existing GUI code to make calls to your DLL. Once you have that done, I will then take the code as is and develop a .Net C# interface, we'll include it into the Visual Studio solution on sourceforge, and then meanwhile you can get aquainted with C# and eventually move onto the C# gui, but at least you will have the core functions in a DLL which will make it much more easier for others to use the DLL in other platform compatible GUI's?

What you think? Good idea?

I too come from a background of assembler 286/386, I remember the days when the double word registers appeared, I would spend hours optimizing code and play with bit masks and XOR techniques to improve the efficiency of my graphics code back in the dos days..... nowadays its all high level development, not even programming anymore, but hey, at least we can get a job done a lot quicker with likes of .Net, and thats the crucial bit, as long as we keep the code clean and optimised and modular, the sky's the limit!

If I convert an MP3 that is around a 100MB, it gets halfway and then just continues to the next one, so only transcodes 50% odd of the original file..... any ideas??

Plus, I have also noticed another bug, if the directory structure is very long, meaning aaaa/vbbbbbb/ccccc/.........../xyzxxxxxxxxxxxxxxxxx.mp3, mediacoder falls over. Looking at the code, I notice the char array is limited to 1024 chars, this causes an overflow when it tries to create the commandline to pass to the shell function.

Also, my other idea was to break up the processing into a chain system that is fully configurable by user? So that adding plugins via a simple scripting feature could be achieved? This would make mediacoder more adaptable by pro-end-users to utilise the huge number of commandline apps and dlls? flexibility and modularity is key, mediacoder will be king if it has a flexible scriptable chain-processing functionality, I would recommend keeping all functions as in loading winamp plugins and loading mencoder/mplayer plugins as a configurable chain system, so that when I start on the C# gui I am able to provide a chaining system, the core DLL should be a set of functions with inputs and outputs and control parameters, no application driving logic should be held in there, this way we can effectively have an interface layer (gui) and an application layer and a facade on-top of underlying functions, all process co-ordination can take place in the application layer.

So basically, you will end up with your C++ GUI and application code in one exe, and all the underlying functions will be available in the mediacoder DLL. This way there will be no hardcoded limitations on how we can utilise the functions in our application layer.

I am also interested in implementing VirtualDub plugin support for video cleaning/effects/transformation.... so once we have a modular design, then anything is possible because by implementing a scriptable chain system (drag-n-drop to amateur users) the sky is the limit!

I've already started on the initial design of the GUI, I can get on with setting up the design of the GUI to incorporate batch file processing, scheduling, etc etc.... and hopefully once you have modularised your functions, I can start on the application layer to utilise the functions and build from there... I've got some experience in GDI+ and I'm hoping to integrate a virtual graphic representation of a chain hook up system, similar to graphedit too.... this is going to be fun!!!!

Optimus, I have 2 issues with encoding FLAC with the latest build.  I get a really loud click at the beggining of the file.  I tested it against the FLAC front end & I didn't get any clicks with that one.  The other issue is that I don't get any tags in FLAC....but I do with the FLAC Front end program.  Thoughts?

Which format are you transcoding from?
