There are some bugs when encoding very large files (>2G):

Hi, ..

recently installed Win7x64
and purchased 2x HD7970

but... Flaccl v0.4
does not work...

AMD drivers 12.6

Flaccl v0.3 works... but... no GCN, no Crossfire.
very small performance increase...?

cuetools.flaccl.cmd.exe --11 --task-size 64 --group-size 64 cd1.wav

crark v3.41 also does not work...

any ideas?

FLACCL is very hardware-dependant, because architectures were rapidly changing at the time it was written. First thing it does is tries to determine which hardware it runs on, and selects parts of code appropriate for that hardware.
I need to debug the general case for unknown hardware to increase the chances of it working on any new GPUs.

i thought it was a Windows problem...
because cRARk for Linux has incredible performance increase HD7970 vs. HD6970
but cRARk for Windows does not even work. strange.

It seems that the --ignore-chunk-sizes option is missing which makes it impossible to use with foobar's default flac profile.

Is this just some missing functionality or is not needed with this version?

By the way, I read that the Nvidia 600 series aren't the fastest with flac-cuda I'm still very happy to see encoding speeds of 200-350 with my GTX670. Thanks!

Only 300x? Depends on the source format of course, but a GTX670 should reach 800x speeds even at -8. Try this:

-q -8 --verify --slow-gpu --task-size 32 --cpu-threads 2 - -o %d

Thanks! I'll certainly try them later this week.

Somehow after updating nvidia drivers to 306.23, flaccl 0.4 stopped working on GTX 570... this is just me?

EDIT: it says
Error: GetDeviceIDs failed: INVALID_VALUE

Works nicely with a GTX560Ti on Win7/32

[Kvanto]

So, can I hope that this will be worked around somehow, or should I stick to old drivers forever?

[Kvanto]

OK I see this project is dead. Then does anyone know what libraries and/or other files that are part of nvidia windows7 driver FLACCL make use of? So I'll be able to copy them, install new driver and then put old files in sandbox environment or overwrite new files. Or what files in driver package are opencl-related? Maybe someone have some info about GetDeviceIDs failed issue? From its name it looks like some general issue that can happen not only in flaccl.

Edit: I also did some googling and it looks like this problem indicates bug in opencl application

Hi. try this:
CUETools.FLACCL.cmd.exe --opencl-type CPU somefile.wav -o somefile.flac

Edit: of course this doesn't solves the issue but at least it works.

Yeah, it works, confirmed. Thank you.

[Miguk]

My netbook has Nvidia ION graphic. The whole time I had to use 267.54 driver as flaccl refused to work with later versions always showing "Out of resource" error after encoding several files.

Today I tried the latest 306.97 version - with the same result.

Then I tried flaccl 0.3 from the command line - it worked!

I tried flaccl 0.4 from the command line - it worked, too! Though a little bit slower than 0.3.

I replaced 0.4 in Cuetools folder with 0.3 files - the same out-of-resource error but after 12 encoded files (before it were 4).

So I decided to say farewell to flaccl as dll and tried to use it as command-line encoder in Cuetools.

With these settings it works now!





BTW, my home computer has an ATI Radeon 5870 graphic card. After upgrading the processor to i5 3570K I don't use ATI opencl anymore - Intel 4000 graphic is faster :-)

I don't know why but FLACCL works again with the latest ATI Catalyst driver (12.10).

[06_taro]

I don't know why but FLACCL works again with the latest ATI Catalyst driver (12.10).

Because 12.9 fixed an issue from 12.4 that OpenCL runtime was broken, resulting in crash or incorrect results on some programs.

[sefr-g]

I've been using and testing FLACCL for some days now, and I ran into some questions:

- will there be tagging support in a future update?

- I've tested up to 24 bits / 96khz / 7.1 channels successfully. will the samples rates 88.2/174.4/192khz be supported at some point (not that I'm a fan of those...)?

- when using flaccl as a command line encoder in foobar, is there a way to force fb2k to use the source wav and not create a temp wav thus slowing the operation down?

- at the moment I'm using batchenc as a gui/frontend and while it skips the foobar delay it lacks tagging. is there a better alternative or a way to include metaflac for the task?

thanks!

btw, here are some benchmarks on a low-end system (with cuetools):

CODE

Celeron E1200 @ 1.6 Ghz, FLAC 1.2.1b -8 -V: 22x, +0%
Celeron E1200 @ 3.0 Ghz, FLAC 1.2.1b -8 -V: 42x, +91%
Celeron E1200 @ 1.6 Ghz, Geforce 210 @ default, FLACCL 0.4 -8 --verify --slow-gpu: 53x, +141%
Celeron E1200 @ 3.0 Ghz, Geforce 210 @ default, FLACCL 0.4 -8 --verify --slow-gpu: 73x, +232%

If it uses temp wav in foobar, I believe you set up it that way. It should do encoding from any source without temp file. Not sure what you say about tags, but if they was in source file, they'll be in final encoded file too.
Btw be careful with anything that is more than 16bits 5.1. It often produces broken files. Verify them after encoding. They may be not completely broken, but some part of it.

[sefr-g]

if I skip the %s in foobar's commandline I get an error: The encoder has terminated prematurely with code 1 (0x00000001)

as for tags, if the source wav has tags (shown in foobar) the resulting flac will have none, at least with the "regular" CUETools.FLACCL.exe [options] <input.wav> commandline.

with verifying you mean listening or just using --verify?

Simply skipping it is not a proper way. check fb2k documentation for correct way, I don't really remember without checking myself.
Thing with tags is a feature of the front end. it will work with foobar, not with FLACCL.exe alone
By verify I mean verify md5 using anything that works for you. personally I use fb2k plugin. maybe FLACCL.exe can do that, I never tried. Original flac package should have ways to do it. If you'll try to mux it in mkv using mkvmerge for example, it will give an errors too. Listening may or may not work as it not always completely broken. It's hard to spot anything that way. BTW while it happens only with more than 16bits audio, it looks like it depends on the _content_ of the audio. For some 24bit audio it never happens, for some other it always happens with any compression level and whatever.

[sefr-g]

alright thanks.
I've noticed the missing - in foobar's commandline although I could swear I've used it initially. now it works, though a bit slower than with plain cmd.exe.
I'll look into md5, thanks again.

Hi, Happy New Year....

i installed drivers 12.10 and was a BIG improvement over 12.6.
but i read somewhere that 12.11 are even better...

uninstalled the 12.10, reboot & installed the 12.11beta11 NET4

it does improove a bit... over 12.10,
but something strange happens...

with Hitachi 2TB HDD goes faster, than using RamDrive...? crazy right?

sadly HDTach 3.0.4 software was discontinued, to test Ramdrive speed.
very strange....

also the latest 12.11beta11 NET4 does not support --group-size 64
gives a Error : internal error: invalid stereo mode.
but with --group-size 32 works ok.

also does not auto-detect the OpenCL name, i guess because i have installled the "Intel SDK OpenCL 2012"

anyway... here are some results:

will the samples rates 88.2/174.4/192khz be supported at some point (not that I'm a fan of those...)?

WTF...not a fan? you really need to change your loudspeakers.
