Lame ACM codec

[Gabriel_Bouvigne]

Here it is!
We finally have am acm codec in the Lame source code.

This is just too good to let slide by. It's true, all those Flaskers that were once asking for it can now have it. it's a new version of the LAME ACM. mitiok is building it on a daily basis it seems. perhaps the fact that this got no response means that people have finally moved on from flask and the like?

[Doom9]

it's just lame.exe and the lame ds filter having it's impact.. you will only find very few guides using an acm codec and normally acm means cbr only (haven't tested this particular acm yet)

... we had to hit the Newbies hard all the time but finally it seems we've done it :D ... no more Flaskers, all use BeSweet and mux with nandub .....

and much better than Fraunhofer ( Radium hack ) ACM ;). Hehe for people like me who just use CBR ( I don't like VBR for AVI since I dislike Nandub. Only DivX3, SBC is too complicated for my tasks ( easy 2 CD rips and stuff like that ) and it does screw up the header information ) a Lame ACM codec is the way to go ;). I hope it completly overwrites the Radium hack. I've seen older Lame ACM codecs and it looked like they were using different FourCC codecs than the Radium/Fraunhofer ACM codec which would cause incompatibility on most computers since the players didn't know that it's just MP3 inside the AVI files.

Does this use the CBR alt-presets?

[ProfDrMorph]

Although the hack to use VBR even though it isn't really support works I prefer CBR since I want to have maximum compatibility. Even with older machines. I'm waiting for TMF or another file format which has the potential to become well known and widly spread that really supports VBR audio before I'll it ( I would like to use Ogg Vorbis; better VBR implementation than Lame because of the MP3 restrictions ;) ).

I prefer using features and not hacks. Which program author ( e.g. Microsoft and it's DirectShow AVI splitter filter ) cares about the hacks some people use? They care about the features of their programs and if someone decides to change his program ( maybe to improve performance or to fix a bug ) then there is a chance that the behaviour of the program changes in such a manner that the hack doesn't work anymore. I don't fear that the hack isn't working anymore some time but I dislike hacks in general.

Nando's way of muxing the VBR audio into AVI was the only possible way, but of course Avery had pointed out it may cause problems .... but only for editing the AVI afterwards, you shouldnt exspect any problems for playback. I dont have any ...
I'm waiting for TMF or another file format which has the potential to become well known and widly spread that really supports VBR audio before I'll it ( I would like to use Ogg Vorbis; better VBR implementation than Lame because of the MP3 restrictions ;) ) love to hear this ( why ;) ? ). If you like to test something in the meantime ( it will be middle of the year until 1st betas are available ) you may check this thread here http://www.powerdivx.com/phpbb2/viewtopic.php?t=108 . Tobias released a 1st Ogg stream implementation under GPL and as i understand it Neo Neko and others were already successful in muxing DivX 4 video streams with Vorbis as Ogg files.
I still dont believe the Ogg format will make TMF ( or MCS as it may be called soon ) redundant, because it doesnt have all the features TMF is specified ( in fact i still dont know what its features are, cant find a spec ) to and maybe is a bit focussed on Vorbis and Tarkin ..... but this maybe my ( balanced ? ) point of view only ...

hehe look a little bit closer at the other threads and you'll see that there's someone who calls himself ProfDrMorph. Now take a look at the left what my nick name is ;) .

Oooopps .... sorry, my bad ! We dont have that much members now, so i normally should have known better :o

Is anyone experiencing problems with this new lame ACM as well? I tried to use it in vdub and ndub, but it doesn't produce propper output. Most of the times i even get the error "couldn't iniciate audio compressor"...

Any ideas?

I haven't tried it yet since it looks like it uses a different FourCC code than the Fraunhofer MP3 codec. So it's of no use for me. ATM I'm playing around with .ogg files.

I think the old version also used the same fourCC code. The problem is also found in this new ACM codec. I still have to find why sometimes it will play, and sometimes it will not.

Also note that the current mitiok build (21/01/2002) is not the latest one. And that decoding is currently disabled (until it works) so you need to keep the FhG one working to decode. And it's not working well yet. So consider it as alpha state. (not "production" compatible)


btw, I'm the developper behind ;)

Nop, but that will be in the TODO (use the same possible presets as the command line, save/restore the encoding config).

Nop, it's the exact same one. The problem is... still unknown. But encoded files will not always work/play. I think it's because of the attached (proprietary) structure that is currently not used, and maybe FhG use it. So I'll have to work on that. Once this is solved, it will be in beta state.

BTW, I think Avery Lee should add a "configure" button for the audio codec. It's sad that it's possible for video and not audio :(

The new beta version is up : http://mukoli.free.fr/lameACM.v0.8.0.zip

It's now compatible with the FhG codec, so you can safely use it. Any bug report is welcome !
