very nice,thank!
any estimation when v2.4 might come?

edit: tiny cosmetics: readme says install.bat, while its register.bat ;)

p.s. any info about cpu usage or something like that? is it better in this field as coreflac or ffdshow audio for example?

edit: have some playback problems with that flac file Ive written about in the eac3to thread. this time madflac wont play the 5.1 dd+ -> flac file (24-bit) inside that .mkv, which played back just fine with coreflac or ffdshow audio. the video is there, but theres absolutely no sound to be heard. when I take that critical 2.0 dd+ -> flac commentary file, which accelerated the fps to 40 with ffdshow audio and coreflac, there are just clicking noises and mpc crashes soon after.
does playback only work with files outside .mka/.mkv ?

Haven't compared that yet.

madFlac is only meant for external files. FLAC files inside of any containers are not supported by madFlac.

THX!

Nice work...-.until now i used illiminable FLAC Source/Decoder.

But it wont decode 24bit Flac (only muxed in mka).
For FALC in Container i use ffdshow ,works perfect.

Is it possible to connect with AC3 Filter at the End in the decodig chain ? I use it to Output AC3 640 SPDIF

Should be no problem. Well, at least I'm not doing anything to disallow that.

It's a combined source/decoder filter. Currently you cannot disable the decoder. What would you need that for?

For people that want to use ffdshow, probably with conversion or down-mixing filters, or another decoder.

madFlac's decoding is bit perfect (as it should be for a lossless codec). Because of that I see no reason to use another decoder. You can still use ffdshow's "raw" audio processing to do down-mixing, conversion and other stuff. FWIW, ffdshow currently cannot handle 8 audio channels (sound gets distorted). So for 8 channel FLACs ffdshow wouldn't work, anyway.

madFlac v1.1 released

http://madshi.net/madFlac.rar

* BASS libraries replaced with libFlac
* seeking works now for > 4GB files, too
As far as I can see, the filter should now be "perfect" for external FLAC files. Please let me know if you find any problems.

tested v1.1 with my speedy gonzales problem commentary track, placed it with same filename outside the movie .mkv as .flac, used commandline mpc with /dub command, but mpc just crashes then with

AppName: mplayerc.exe AppVer: 6.4.9.1 ModName: coreflacdecoder.ax
ModVer: 0.4.0.46 Offset: 00014e34

edit: allright, crash was caused by coreflacdecoder, which was still active until I unregistrered it, despite all block setting.
still, also with v1.1 those stupid clicks in the commentary track :S

just noticed when playing back that commentary track in .mka with normal media player it reported the same length as the movie track, but the time elapses quite some bit faster. could it be possible that the commentary track was recored with a different number of fps and this might be the reason why he accelerates the video? is there a way to slow it down to 23.976fps then, without having it to sound stupid?

Are you sure that the commentary track is ok? Maybe there's something wrong with that track?

How fast does the track play with madFlac? If the speed is ok with madFlac, the problem must be related to the mka container somehow.

@madshi

Ive Problems with madflac

Ive no correct channel decoding on 5.1 /6.1 FLAC .
FFdshow and illiminabel works perfect. But with madflac ive no Center Channel...i tried all System/Soundcard Speaker Settings, all the same
That's strange. It seems to work for me. At least I've forced the ffdshow raw audio decoder into the chain and it shows that there's some action on the center channel (see "volume" page, check the bottom most checkbox).

Checked with an AviSynth script that loads 6 FLAC files representing 6 channels, and all are fine. :)

Mine is 6 seperate FLAC files, his is probably a 5.1 channel FLAC file. It may well be the way it's encoded.

Is it possible to swap the channels in such a file, like with AviSynth, and losslessly encode again?

madshi

Yes, you can do e.g. "eac3to source.flac dest.flac -0,1,2,3,5,4" to swap the last two channels.

...the encoded FLAC Files are Ok....all Channels present . Thats not the Problem, only the decoding with madflac is wrong.

Friend of mine has the same Problem :) And the PC on my work too
FLAC Output with madflac analog Output has no center channel
Illiminable ffdhow and CoreFLAC are working , i m sure its not a Problem caused by my Setup

Very interesting :

When i add ffdshow Audiio Processor behind madflac the Output is OK !
Without ffdshow Center Channel isnt present (i can hear itvery silent in L R )

The Decoder appears not as "madflac" in the Dshow Player Filter Properties when you play a Flac File as like as other Decoder ? right ?...
http://img520.imageshack.us/img520/3448/sourcegn8.th.png (http://img520.imageshack.us/my.php?image=sourcegn8.png)

Ofcourse you can acces the Options whne you click Filter Options/"Source File :customized Graph" in Zoomplayer or in mpc its in "Play/Filters"

Its marginal, but maybe you can make the Decoder visible as "madflac" for Dshow Playback so that the Decoder is listed in the Filter/Graph Optiones so we can acces the Options from there ...would be more obvious :)

And i have a 6.1 FLAC File reencoded from DTSHD 6.1 with latest eac3to. eac3to info is DTS HD "6.1" 24
and .wavs Output is 7 mono waves

But Madflac Info on 6.1 Flac 7.1 CH
I made a few Tests and all Flac Files reencoded from dts (hd) 6.1 are 7.1 in madflac Properties.
I Dont know if its only a wrong info or madflac decodes them wrong as 7.1

I'm using MPC and and not ZoomPlayer, and in MPC the madFlac options are available in the same place where any other decoder's options are available, too. Not sure what madFlac would have to do different (technically) to show up in ZoomPlayer where you want it to show up. If that's important for you, maybe you can ask ZoomPlayer support about this? They might be able to tell you what a decoder needs to do exactly to show up where you want it to show up.

And i have a 6.1 FLAC File reencoded from DTSHD 6.1 with latest eac3to. eac3to info is DTS HD "6.1" 24

I Dont know if its only a wrong info or madflac decodes them wrong as 7.1
LPCM tracks are 7.1, even if the soundtrack is only 6.1. The back channel is then simply stored twice with identical data. DTS Discrete can be 6.1 or 7.1, I believe. TrueHD is usually 5.1 or 7.1, I think. In order to avoid having so many different channel configurations eac3to is intentionally converting 6.1 channels to 7.1 by doubling the 7th channel. FLAC should handle such situations very efficiently. I expect there to be no noticable disadvantage in file size.

Could it be because of my old CPU (no SSE)?

Can you post the crash report? At least in which dll it crashed? If it's inside of libFlac.dll then it might be SSE related. Honestly I'm not sure which version of libFlac.dll I'm using. You could try replacing that libFlac.dll (which is distributed with madFlac) with a SSE free version to see if that fixes the problem.

I got a similar bug report for my program CUE Tools which uses libFLAC, and indeed there is sometimes a problem with libFLAC's SSE detection routine. I'm pretty sure this is the same problem here because I was able to reproduce it on one of my older computers. Try this compile (http://www.moitah.net/misc/libFLAC_DLL_TryCatch_1.2.1.zip) of libFLAC.dll, I compiled it with USE_TRY_CATCH_FLAVOR defined which changes the way the error handling in the SSE detection works.

@Madhsi

I simply mean that in mpc for example for AC3 the Decoder apperas as AC3 Filter, or for x264 its CoreAVC or ffdshowVideoDecoder etc
You can click on the Decoder to enter Options.

Thats what i mean for madflac too because the Decoder appears not as madflac as like as AC3 Filter for example....but its marginal , forget it :)

Ah, I see what you mean. madFlac shows not with "madFlac", but with the filename of the FLAC file. That should be easy to change.

Ouch. Didn't test madFlac on Vista64 yet. But I've already had trouble with installing the simple "Dump" filter (MS filter which ships with GraphEdit) on Vista64! So it seems that installing 32bit DirectShow filters on Vista64 is a general problem. I'll look into this later. Can't promise a specific date for a fix, though.

This is just for playing flac without a container, yes?

I have lots of working 5.1 flacs but as soon as I put them in an mka and mkv and use ffdshow, the sound breaks up every few seconds.

Can I ask what people are using to decoder flac inside a mkv container?

Currently I have all my FLACs as external files. I might add decoding support for FLACs in containers, but I'm not sure if I can make it better than ffdshow.

The Vista problem might be because of UAC. Try disabling that. And of course register the filter with admin privileges.

You are right! Disabling UAC lets me install it! I've never had to do that with a codec before though.

Hmmm... Do you have some "strange" filter in the "external filters" section? Don't know what else could stop madFlac from working...

What happens if you just drop a FLAC file into GraphEdit without manually choosing madFlac. Does GraphEdit automatically choose madFlac and does playback work that way?

Maybe you still have another filter installed (e.g. CoreFlac)?

"The format is not supported."

I do not have coreflac installed, nor any other flac source filter nor decoder, but clearly somethings wrong on my end, as seems to be more and more often the case:(
That's a bit strange. Maybe there's another filter which tries to read the FLAC file but fails. Does MPC show you which filter it used for the "cannot render file"?

madFlac v1.4 released

http://madshi.net/madFlac.rar

* bugfix: "madFlac" is shown in MPC/ZoomPlayer now instead of file name
* bugfix: maybe installation in Vista64 works now without having to deactivate UAC (not tested)
* bugfix: using different libFlac.dll build to avoid crashes on older CPUs
* in addition to the "madFlac Source" there's now a "madFlac Decoder" filter for decoding FLAC inside of MKV (or other containers)
The new "madFlac Decoder" filter for MKV FLAC decoding is not very well tested yet. So I'd be happy about some feedback. Especially I'd like to know if there are audio dropouts or audio sync problems or anything like that. If everything works great, I'd like to know that, too, of course. :) Thanks.
