The last release is based on aoTuV Beta5. Anyone knows the status os the project, if there are plans to a next release?

As far as I know, it's dead

[lvqcl]

I wonder is it possible to determine the most time-consuming routines and manually port them from lancer to current aotuv?

[lvqcl]

I'm trying to mix "aotuv5.7+bs1" codec and lancer. Only 55...60% speed increase

There are several routines that were changed from beta5 so I cannot accelerate them with lancer code.

55-60% is very good speed boost. Can you post your code and binaries?

Some results for dual core:
Lancer 20061110 sse3+MT: 10 seconds
aotuv5.7b-P4: 7 seconds

That's 40-50% of speed gain.

Currently I'm trying to make OPENMP work. Some changes made between b5 and b5.7 interfere with OPENMP support code. My current version just doesn't support multi-threading.

I tested several encoders with foobar2000 as a frontend (dual-core processor, but only 1 encoder process at a time).

Lancer SSE3: 60.79x realtime
Lancer SSE3+MT: 84.00x realtime

Oggenc2 (aotuv5.7) from RareWares: 29.16x realtime

b5.7+bs1 patch (MSVC): 26.11x realtime
b5.7+bs1 patch+lancer (MSVC): 41.07x realtime

I will upload the code and exe files one of these days.

[lvqcl]

I decided not to add OpenMP support, it's too complicated for me. And, 2 parallel single-threaded encoders are still better than 1 multi-threaded.

Patches and Win32 MSVC compiles: http://www.hydrogenaudio.org/forums/index....showtopic=76272

[IgorC]

Here is +45% speed gain.
Thank you,lvqcl

I didn't find any issue with this version until moment.

OK, folks, I finally got round to compiling under ICL 11.1.048. The results are from my development system which is an E4300 cpu clocked to 3GHz with 4GB OCZ Reaper in a Gigabyte EP45-DS3 running XP Pro SP3.

The first run is using the regular P4 ICL compile of aoTuV5.7 that's on Rarewares, the second is using lvqcl's Lancer-style patch. I'll leave you to do the maths, but the speed gain is somewhat alarming!!

So, I suppose you will want to try this out? You can d/l from here: http://www.rarewares.org/files/ogg/oggenc2...b5.7-Lancer.zip

If this appears stable, and I'd like feedback regarding this, then I'll make it generally available on Rarewares.

Quick test on Windows 7 64 bits on E6600 using foobar2000 v1.0 beta2 with pipelining and times indicated by foobar:

Converted 4 CD Box Set encoded at FLAC -8:
oggenc2.85-aoTuVb5.7-P4 with q5.0 -> 3:39 (219 secs)
oggenc2.85-aoTuVb5.7-Lancer with q5.0 -> 2:14 (134 secs)

Converted 5 CD Box Set encoded at FLAC -8:
oggenc2.85-aoTuVb5.7-P4 with q5.0 -> 5:11 (311 secs)
oggenc2.85-aoTuVb5.7-Lancer with q5.0 -> 3:23 (203 secs)

Thanks to all for this fantastic speedup!

[lvqcl]

Core2Duo E4300, --quality 5, 44.1/16/2ch:

unaccelerated version from RW: 29,9x realtime (=>100%);
accelerated (my MSVS9 compile): 44,0x realtime (~147%);
accelerated (ICL 11.1.048 by john33): 48,8x realtime (~163%);

//Lancer 20061110 (based on b5): 62,9x realtime (~210%).


Yes, ICL compile is faster than MSVS one. Old Lancer is even faster, but further acceleration is beyond my knowledge. To anybody: feel free to accelerate it further.

[lvqcl]

Two more suggestions:

1) To have more consistent date format, I think it is better to define CPDATE macro to e.g. "20091201"

2) oggenc2.exe says that it is "based on aoTuV exp-bs1" (and that isn't true). It was my mistake in the very first version of the patch... Current version reports "based on aoTuV b5d [20090301]". Please fix it.

[skamp]

Is the patch supposed to make it faster on Windows only? Last time I compiled it under linux, it didn't make vorbis encoding any faster.

[lvqcl]

Don't forget to define __SSE__, __SSE2__, __SSE3__ macros.

...At least The_Sven compiled aoTuV-beta5 for Linux with success.

I found a strange problem... The difference between various compiles is usually insignificant, but not always.

When (input samplerate = 22050 or 24000 Hz) AND (encoding quality > 5.000) there is noticeable difference between ICL and MSVS compiles.

For example: input file is 22.05kHz/2ch; quality is 8. => "Nominal" bitrate is 138.4 kbps.

P3/P4/Lancer from RW (ICL): 116.1 kbps
venc from Aoyumi (MINGW32?): 116.1 kbps
generic version from RW (MSVS 9): 136.3 kbps
my compiles (MSVS 9): 136.3 kbps.

(For 24kHz/-q8 the difference is 123.0 kbps for ICL vs 144.5 kbps for MSVS).

Don't forget to define __SSE__, __SSE2__, __SSE3__ macros.

I must admit that linux is not my favorite OS and I didn't have it installed on my HDD.

Maybe The_Sven can help you more than me... At least you can take his versions of xmmlib.c and xmmlib.h.
Here they are, extracted from vorbis-lancer-gcc-HEAD.tar.gz:  xmmlib.zip ( 3.82K ) Number of downloads: 259

[lvqcl]

Fixed with a new upload available on the same link.

Great. Yet it still writes "BS; LancerMod(SSE3) [Dec 2 2009] (based on aoTuV b5d [20090301])" to *.ogg files (although it's not a big problem ).

Even after fixing compiling errors, oggenc fails with "undefined symbol: PCS_NRNR". Recompiling vorbis-tools also fails with several errors regarding "undefined reference to…".

Well, PCS_NRNR is defined in xmmlib.c and used in mdct.c and smallft.c... I think you should add "xmmlib.c" and "xmmlib.h" to "libvorbis_la_SOURCES" variable in aoTuV makefile (as it done in this compile)

Duly amended with a new version on the same link.

Thanks!

Here is an x64 compile of oggenc2.85 with FLAC support. Currently this is based on the standard 1.2.3 libs, but if some kind people would like to test this and confirm whether it's OK, or not, I'll go ahead and build an aoTuV version.

Any chance to have an x64 compile of this Lancer mod too ?
