ac3/ogg decoder/plugin for winamp

[N_F]

I've been searching for a while now after a plugin to winamp which will make it possible to play ac3 and/or ogg through it, with no success. Does anyone have of know of such a plugin?

Alternatively, is there another way to play ogg/ac3 without having to mux them into an avi-file first (players seem to be able to play these audio streams under this circumstance)?

The reason I wanna do this i mainly because I want to compare mp3/ac3/ogg.

lousy ac3 decoder plugins :

http://www.liquidaudio.com/products/liqplayer/plugin/index.asp

good ogg decoder plugin :

great mp3 decoder plugin :

Thanks! I'll try them when I get home.

BTW, I hope you didn't spend half an hour just searching these down for me... ?

Thanks DSPGuru,

I've been looking for AC3 decoder plugin, too, recently. I found the ac3dec but the version I got didn't allow seeking in AC3. Guess, I'll try the current version you provided the link to.
Ah, it would be nice to have an Azid Winamp plugin or even DirectShow filter, but I guess we'll never see such a thing.

Thanks for so much patience in this forum.

naaa.. it only took me few minutes to gather all those links.. :)

as for azid-based winamp ac3 decoder,
it's a great idea, but it seems like no-one finds the time to do it.. :(

[DSPguru]

i use wmp.

[ookzDVD]

@DSPGuru,

Thank you.... ooops.... sorry,

it's my fault, after I un-install Mpeg2parser.ax,
WMP can play the AC3 very well.

@DSPGuru,
thank you for the info,

@valex,
we should call you "AC3Guru" ;)
I think the channel mapping is screws up :(

Thanks. I actually never got winamp to play ac3, hope this works better.

[Valex]

Ah! AC3 for Winamp discussion is here :).

Does anyone have Winamp plugin working?

@ookzDVD
Can you try this test file:
http://xvalex.hotbox.ru/download/ac3test.zip
Also try different outputs - standart DirectSound, WaveOut.

[N_F]

The ac3 decoder plugin for winamp that DSPguru's linking to is working great for me. Are you the author?

[Valex]

2N_F
Yes. And just released a new version with configuration like in AC3Filter:
http://xvalex.hotbox.ru/download/in_vac3_0_2a.zip

2ookzDVD
Can you try new version?

[rjamorim]

Great new version, Valex! Works very well here.

But maybe you could add "non-configurable" information (Bitstream information, levels, CPU usage...) to the file info (alt-3) window?

Then, the bitstream information can be removed from the scrolling title.

Thanks a lot for the good work. :)

Regards;

Roberto.

Edit: CPU usage doesn't shows here. Stays at zero. AMD XP 1500+, Win2k.

[ookzDVD]

@valex,

Thank you for the latest version,
but somehow it still reporting that my AC3 file is Dolby Surround,
with only Left & Right channel, the output is only to the left speaker. :(

[Valex]

2ookzDVD
but somehow it still reporting that my AC3 file is Dolby Surround,

How I understand. I did not test it on DS files because have no any... Can you send me a part of this file (~100k)?

[Rrrough]

@valex

your plugin is working really great for me. especially do I like the master gain feature and the fact, that the whole file is seekable now. the sound quality is fine !!!
With the older plugin I had (in_ac3) there was only low sound and only the first 5 minutes were seekable.
great work !

cheers

Did it:
http://xvalex.hotbox.ru/download/in_vac3_0_3b.zip
Also it is now supports AC3-PES files.

2ookzDVD
You can really help me if you can send me a part of this problem file.

[janosch]

God bless you all,
i am waiting for this plugin since two months.
And now the link ís dead :p

@Valex where can i get this file ?

[Valex]

I know that some people have troubles with my hosting. So now I'm moving this project to Sourceforge. But it can take some time, so if you promise to find lots if bugs I can email it to you ;-).

Great! Thanks a lot.

Works perfectly here. Including CPU usage. :)

@Valex,

Sorry, I was my mistake, it was 2.0ch file, so the input is only L&R,
but somehow it still played only L channel.

I just try it with 5.1ch at my home, and everything is working well,
is that possible to choose the "output" setting not only stereo?

Thank you.

[Bluedan]

Is there another hosting space for this plugin?
I'm still unable to download, IE says something weird like "cannot copy file, check for write protection or if file is already in use...". Never occured to me before.
Firewall? Here it's Tiny Pers.pro.
How did you all manage to dl?

Well, as usual user fault: seems to be a temporary issue on my girl-friends computer- she denies to having messed around with some settings...

[Valex]

2ookzDVD
Try this:
http://xvalex.hotbox.ru/download/in_vac3_0_4b.zip

It was a bug with stereo files decoding.

[Valex]

@Bluedan
Sourceforge project was approved, so now you can download it here:
http://sourceforge.net/projects/winampac3/

[ookzDVD]

@Valex,

Sorry I just reply you today,
the 04b is working with 2_0 Ac3 file now.

Btw, is that possible to get the 5.1 output rather than just stereo
output ?

Thank you.

I have this working with Winamp 2.81. Winamp 2.78 does not work. Also it may not work with different output plugins (if you are using non-standart output plugins)

[ZYron]

@Valex

Very nice Plugin ... works great!!

@All

I like to transcode a AC3-File to a AC3-CD but got no luck with
Headac3 or BeSweet 1.4.. when I Play the file with Azid i got the
following error messages and the Sound is buggy.

[00:00:01.504] E7: CRC error
[00:00:01.504] W1: Found sync after 32 bytes
[00:00:01.504] E7: CRC error

[00:00:01.504] E7: CRC error
[00:00:01.504] W1: Found sync after 32 bytes

with the in_vac3_0_5b.zip i got no problem playing this file in
Winamp. So I used the WaveOut Plugin and got a 6 Channel Wave file but
this is very big.. after a while I used the out_vorbis.dll and got a
nice 6 Channel Vorbis file .. not so big! The question is how can I
use this File to get a AC3-CD ??

Ciao ZYron

[Valex]

Most likely is is not a pure AC3 stream but PES-AC3. Look at file information (Alt-3) in Winamp (last checkbox shows it).

[ZYron]

@Valex,

Yes .. it is a PES-AC3 ! How can i convert it to a normal AC3 ?

Ciao ZYron

[DSPguru]

you can fix it with BeSplit/BeSliced. :readfaq:

[ZYron]

@DSPguru

I already tried this but this is not working .. Original Ac3 Ca. 120MB
fixed ca. 13MB ;((

BeSplit v0.9b4 by DSPguru.

[DSPguru]

interesting.
can you cut 100kb of this file and attach in here ?

[ZYron]

@DSPguru

OK i try ;) .. Have attached it to the post hope you can download it.


Thx for the Help so far

Ciao ZYron

[DSPguru]

sorry mate, your stream is totally f*cked up.
i get endless crc errors.

[ZYron]

@DSPguru

..but the winamp Plugin from Valex play the AC3 Correct ;-)
OK thx DSPguru so I will have to free up some Space on my Harddisk decode it to a 6 Channel Wave using the Winamp Plugin and feed this into BeSweet I think.

Ciao ZYron

[Valex]

@ZYron

I usually do it with Graphedit. But you'll need some additional filters:
http://xvalex.hotbox.ru/download/filters/dump.zip
http://xvalex.hotbox.ru/download/filters/nullip.zip

Graphedit itself:
http://xvalex.hotbox.ru/download/graphedit.zip

In Graphedit:
File->Render Media File (your file). Then delete everything after 'MPEG2Splitter' filter.

Insert NullInPlace and Dump filters (Graph->InsertFilters->DirectShow->...). When you add dump filter it will ask you for output file name.

Connect MPEG2Splitter output to NullInPlace input. With right mouse button open NullInPlace filter properties and select audio format with media type = MEDIATYPE_Audio and MEDIASUBTYPE_DOLBY_AC3.

Connect NullInPlace output to Dump input.

That's all. Then just run graph with play button on toolbar. It will take some time to convert (prgress is not shown).

rename your .ac3 file into .vob and feed it into BeSweet.
it should work.

ps,
if you're just interested in "fixing" the stream, use vstrip with the following commandline :
vstrip.exe [infilename].ac3 -o [outfilename].ac3 -d 0xbd 0x83

[ZYron]

@DSPguru

Thx .. finally this works !!!

Valex, you are truly the AC3 king! Great plugin, it works very well here and the seeking is wicked fast.

I noticed the SPDIF feature request is already on SF. Of course I'd be more than happy to help you debug it if soomething like this could be made possible:) Thx again.
