| zequence | Need to get a live system working, and so far whatever I try, there's always something putting a stop to things | 00:16 |
|---|---|---|
| Len-nb | zequence, LMMS added to "generation" in seeds. | 00:48 |
| Len-nb | We'll see how it goes | 00:48 |
| Len-nb | micahg, besides -look, ubuntustudio-icon-theme and ubuntustudio-default-settings need to be uploaded. | 00:52 |
| Len-nb | The changes in one match the other. | 00:53 |
| Len-nb | zequence, if our ISO builds with lmms, then we will need to generate a *.desktop file to go with it. | 00:56 |
| Len-nb | zequence, I think that is my studio work for the day (week?) | 00:57 |
| micahg | Len-nb: ACK | 01:02 |
| Len-nb | micahg, thanks | 01:02 |
| zequence | Len-nb: I find that our categories don't make much sense | 01:13 |
| zequence | Wouldn't say lmms is well categorized under generation, as it is a seuqencer | 01:14 |
| Len-nb | It is where qtractor is. | 01:14 |
| Len-nb | I would like to have fewer audio metas | 01:15 |
| zequence | But, I can see there's other categories within audio that are used strangely as well | 01:15 |
| zequence | Yea | 01:15 |
| zequence | One would really be enough | 01:15 |
| Len-nb | Or one pro and one not? | 01:15 |
| zequence | If we want to use subcategories, we can add those in the seed source, for reference | 01:15 |
| zequence | You're thinking about standard desktop audio vs pro audio? | 01:16 |
| zequence | Perhaps standard desktop stuff should be in its own meta | 01:16 |
| Len-nb | Standard desktop should already be in desktop | 01:16 |
| Len-nb | Maybe one would be fine | 01:17 |
| zequence | Yea, that is probably the best one. If someone uses another desktop, they will already have a standard set of desktop audio apps | 01:17 |
| Len-nb | What about things like jack for video? | 01:18 |
| zequence | That should be a dependency in video | 01:18 |
| Len-nb | I think video depends on a basic audio meta now. | 01:18 |
| zequence | Audacity only from what I can see | 01:20 |
| Len-nb | no it doesn't, jack should be there as there are some things that use jack for timing. | 01:20 |
| zequence | Perhaps we should leave this for later | 01:20 |
| zequence | We need to thoroughly go through each workflow | 01:21 |
| Len-nb | we have 5 audio metas. | 01:21 |
| zequence | I think at least we could put all the audio metas together for now | 01:21 |
| zequence | There's a lot of stuff we could improve for all metas | 01:22 |
| Len-nb | the name ffmpeg should be replaced | 01:22 |
| Len-nb | It is now av-something | 01:22 |
| zequence | Well, that is one of those details that someone going thoroughly through video might want to look at | 01:23 |
| zequence | You could add workitems about that | 01:23 |
| Len-nb | libav now | 01:23 |
| zequence | ffmpeg does install the av stuff though | 01:23 |
| Len-nb | Ya, but that will not last forever | 01:24 |
| zequence | This package contains the deprecated ffmpeg program. This package also serves as a transitional package to libav-tools. Users are advised to use avconv from the libav-tools package instead of ffmpeg | 01:24 |
| zequence | I'm hoping this kernel build actually get me somehwere. Been working on getting to work for two days now. That's no way of getting things done | 01:25 |
| Len-nb | I gave up on kernels soon as I could :) | 01:26 |
| zequence | Yea, well. I really need one that I can actually use for something | 01:26 |
| Len-nb | being bale to use premade kernels is nice | 01:26 |
| zequence | That's where I'm out of luck | 01:27 |
| Len-nb | *able | 01:27 |
| zequence | There's not a single one I can use right now, save the 9.10 realtime kernel | 01:27 |
| zequence | I'm not that eager to install puredyne in 2012 | 01:27 |
| Len-nb | That works at all or just for one task? | 01:27 |
| zequence | That works at a reasonable latency | 01:28 |
| Len-nb | Right | 01:28 |
| zequence | The Debian rt is quite nice, but there's a bug in the system. If I was not busy trying to find something that works, I might actually have time to figure out what it is | 01:28 |
| Len-nb | Is that a 2.6* | 01:28 |
| zequence | Shuts down an irq after a while. In this case, the firewire device | 01:28 |
| zequence | Debian Wheezy. 3.2 | 01:29 |
| zequence | Same as Precise | 01:29 |
| Len-nb | (2.6 in 9.10) | 01:29 |
| zequence | Yea | 01:29 |
| zequence | 9.10 was the last Ubuntu to contain a -rt kernel | 01:29 |
| Len-nb | That is disappointing | 01:29 |
| zequence | linux-lowlatency won't work, unless I install Ubuntu 10.10 | 01:30 |
| zequence | And there's no garantee that is up to par either | 01:30 |
| zequence | I wish I had done some cyclic tests on the -lowlatency back then | 01:30 |
| Len-nb | So what changed from 2.6 to 3*? | 01:30 |
| zequence | Practical tests were giving wonderful results | 01:30 |
| zequence | I built a 2.6.38 kernel on 12.10 recently, thinking I'd get better performance, but no | 01:31 |
| Len-nb | Have some buffer sizes gone up? | 01:31 |
| zequence | There's something outside the kernel that seems to affect the performance as well | 01:31 |
| zequence | Or, I just don't have good enough testing data | 01:32 |
| zequence | There was a weird time when we were testing -lowlatency during 10.10 | 01:32 |
| zequence | It was 2.6.37 | 01:32 |
| zequence | We were getting awesome results. All of us | 01:32 |
| zequence | Then, a week later, or so. The same exact kernel, after a system update. Worse performance | 01:33 |
| Len-nb | I wonder if something like upstart or dbus is a problem | 01:33 |
| zequence | I don't know enough about the inner workings of linux in order to have a clue. But, if I can just get a 3.2 kernel working on Ubuntu without the irq bug that Debian suffers from, I can relax and start working on what I really should be doing, namely preparing a 1.0 version of the audio software that my band is to use for live gigs | 01:35 |
| Len-nb | I wonder if the slackware audio distro has this problem. | 01:35 |
| Len-nb | It is totally roll your own. compile everything. | 01:36 |
| zequence | It is related to audio somehow. Only audio devices were getting borked | 01:36 |
| zequence | But, it's not in the vanilla kernel. It's something Debian specific | 01:37 |
| Len-nb | Is it the FW stack? | 01:39 |
| zequence | This time it was. On another machine it was a pci audio device | 01:40 |
| zequence | This time it was when using jack. the other time pulseaudio | 01:40 |
| zequence | So, alsa | 01:41 |
| zequence | er.. :P | 01:41 |
| zequence | I'm getting tired now | 01:41 |
| zequence | I don't know. Seems like there should be no connection at all when I think about it | 01:41 |
| zequence | Just happened to be two audio devices both times | 01:41 |
| Len-nb | just found this: | 01:45 |
| Len-nb | jackd has to run with realtime priviledges. One way to do this on Slackware would | 01:45 |
| Len-nb | be to use set_rlimits. Since 12.2 there's another way, though experimental. If | 01:45 |
| Len-nb | you have a filesystem that supports posix capabilities (reiserfs does not), you | 01:45 |
| Len-nb | can grant jackd the rights to run in realtime mode, even when started as normal user | 01:45 |
| Len-nb | with the following command: setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/jackd | 01:45 |
| Len-nb | zequence, That sounds like it sets bits on the binary file itself. | 01:46 |
| smartboyhw | What the...My newest dist-upgrade wants to remove ubuntustudio-desktop!!!! | 08:13 |
| smartboyhw | Hey ttoine | 08:37 |
| ttoine | smartboyhw, hello | 08:47 |
| ttoine | zequence, the ticket for emails is handled ! I just get the email notification | 08:48 |
| ttoine | zequence, if the jetpack package cannot be installed, I have another way to share posts | 08:48 |
| smartboyhw | ttoine, yes:D | 08:50 |
| ttoine | smartboyhw, it means that like any other ubuntu flavour, we are a community ! | 08:54 |
| smartboyhw | ttoine, :D;D | 08:55 |
| ttoine | smartboyhw, and I am happy, the delivery of my brand new VPS is this morning ! | 09:00 |
| smartboyhw | ttoine, :D | 09:00 |
| ttoine | and my brand news VPS is delivered this morning ! | 09:01 |
| * ttoine feel happy this monday morning | 09:01 | |
| smartboyhw | :D | 09:04 |
| zequence | ttoine: I did see that they put the ticket in queue, but still no email adresses from what I can tell | 09:11 |
| smartboyhw | zequence, well at least they will do it:P | 09:11 |
| ttoine | zequence, yes, but you can notice than it seems to be faster than for jetpack | 09:12 |
| zequence | I think that's just coincidental | 09:12 |
| zequence | Don't think they have many people working on those tickets | 09:13 |
| zequence | I've been trying to get a well performing kernel all day tomorrow | 09:14 |
| zequence | ttoine: Have you built an -rt with nvidia support? | 09:14 |
| zequence | I'm getting awful results from cyclic testing, but finding out now that it doesn't tell you how well audio performs | 09:15 |
| smartboyhw | zequence, uh I have -rt kernels here built, but without Nvidia support | 09:15 |
| zequence | smartboyhw: Yes. That is the normal result, without patching either the linux source, or the nvidia source further | 09:15 |
| smartboyhw | zequence, you mean http://linuxmusicians.com/viewtopic.php?f=27&t=7496 ? | 09:16 |
| zequence | all day yesterday* | 09:16 |
| zequence | smartboyhw: No | 09:16 |
| smartboyhw | zequence, er? ( I don't use Nvidia anyway:P) | 09:16 |
| zequence | Without nvidia proprietary drivers, you might get worse performance | 09:17 |
| smartboyhw | zequence, so what you want is a -rt kernel with the "proprietary" drivers | 09:18 |
| astraljava | smartboyhw: Probably a conflict with packages, the archives are fluxuating. Don't worry, try again later. | 09:20 |
| ttoine | zequence, you may use the nouveau driver, no ? | 09:20 |
| smartboyhw | astraljava, try again what? | 09:20 |
| ttoine | with -rt kernel, the only good result I have ever had is on full Intel pc | 09:20 |
| zequence | ttoine: Yes, but at a cost to performance | 09:21 |
| astraljava | smartboyhw: dist-upgrade | 09:21 |
| zequence | Funny enough though, I was getting bad results from cyclic testing, but no xruns at really low latency with my FW device | 09:21 |
| smartboyhw | astraljava, ah:D | 09:21 |
| ttoine | zequence, yes, for sure. but I was one of the first to use a rt kernel with Ubuntu, I guess with Ubuntu Edgy. It has always been special to use. I thank a lot Alession for his work ! | 09:22 |
| ttoine | zequence, what do you mean with "bad resulst from cyclic testing" ? | 09:23 |
| zequence | ttoine: There's a test for determining latency, called cyclictest | 09:23 |
| ttoine | ok | 09:23 |
| zequence | But, it doesn't tell you how well your audio hardware will perform against the system of course | 09:23 |
| ttoine | zequence, sorry, I am not very concentrated. I am playing with my new server | 09:24 |
| zequence | I was getting exactly the same results from both -rt and -lowlatency on this machine, on 12.04 | 09:24 |
| zequence | Bad results from the cyclictest, that should give xruns | 09:24 |
| zequence | But, no xruns | 09:24 |
| zequence | Anyway, seems like I'm actually getting the performance I need now | 09:25 |
| smartboyhw | Well anyway I will try to build a -rt kernel with the Ubuntu drivers, but I'll wait till 3.8 releases. There are no -rt patches for 3.7... | 09:25 |
| zequence | Just need to start using the software and see how it goes | 09:25 |
| zequence | jack2 1.9.9 is out. I'd expect it to appear in raring sometime soonish | 13:23 |
| zequence | should hopefully be a lot more stable than previous version | 13:23 |
| smartboyhw | zequence, Oh! | 13:43 |
| smartboyhw | Hi scott-work | 13:45 |
| scott-work | good morning smartboyhw | 13:48 |
| scott-work | zequence: ping | 13:48 |
| zequence | scott-work: pong | 13:56 |
| smartboyhw | Eh scott-work zequence you guys ping-ponged without any discussion?:? | 14:11 |
| zequence | Len-nb: There's really only one thing I can think of which might need some consideration, when it comes to having only one audio meta | 14:20 |
| zequence | Len-nb: plugins | 14:20 |
| zequence | Either we find a way to make it easy for users to find "recommended" applications no matter what application they use with the plugins, or we add a ubuntustudio-audio-extra meta (which could include a lot more than audio plugins) | 14:21 |
| zequence | Sorry, "recommended" plugins | 14:21 |

| Len-nb | zequence, whats with im-switch/im-config conflicts? It looks like one depends on the other. Has one been upgraded and the other not? | 23:05 |
| Len-nb | zequence, ^^ to do with ISO builds. | 23:06 |
| micahg | needs a seed change/meta upload | 23:06 |
| micahg | same that xubuntu did | 23:06 |
