| abstrakt | anyone awake :) | 01:12 |
|---|---|---|
| abstrakt | looking for anyone here who has successfully done a simple video montage by putting clips of video to music | 01:13 |
| abstrakt | for example | 01:13 |
| abstrakt | cuz that's what i am trying to do, but kino doesn't seem to have any features for doing this | 01:13 |
| rlameiro | try openshot or pitivi | 01:14 |
| abstrakt | ok yeah pitivi has the audio+video sequencing | 01:15 |
| abstrakt | now the tricky part :) | 01:15 |
| abstrakt | how can i crop | 01:15 |
| rlameiro | well i dont know | 01:16 |
| abstrakt | e.g. have 4 different vid clips playing in e.g. four "boxes" | 01:16 |
| rlameiro | but i should be easy | 01:16 |
| rlameiro | when i did video plus audio i used xjadeo only for the video and edited the audio on ardour | 01:17 |
| abstrakt | right well i already recorded a song in ardour | 01:17 |
| abstrakt | so that's done, that was a fairly decent experience, ardour is nice | 01:17 |
| abstrakt | will be nicer when it has midi, but fundamentally i don't want to be making midi music anyway | 01:18 |
| rlameiro | well import the audio to pitivi | 01:18 |
| abstrakt | i guess maybe i need openshot now, don't think pitivi will crop | 01:18 |
| rlameiro | and the video | 01:18 |
| abstrakt | yeah i already did that | 01:18 |
| abstrakt | that'll be fine, but now i need to crop/collage/montage | 01:18 |
| rlameiro | i think i used openshot | 01:18 |
| abstrakt | e.g. multiple clips in the same vid | 01:18 |
| abstrakt | k i'll try openshot next | 01:18 |
| rlameiro | yeap, maybe openshot suit best | 01:18 |
| rlameiro | sleep time now | 01:19 |
| rlameiro | cya and good luck | 01:19 |
| abstrakt | comes with 10.04 but not 9.10 :( | 01:19 |
| abstrakt | well pooh | 01:19 |
| acerimmer | abstrakt? | 01:39 |
| === acerimmer_ is now known as acerimmer | ||
| abstrakt | ok so now that i've created my video in openshot | 05:02 |
| abstrakt | i wanted to export it as h264 and mp3 | 05:02 |
| abstrakt | and, probably, flv | 05:02 |
| abstrakt | but if i choose flv then i only see h263 in the other list | 05:03 |
| abstrakt | what's up with that? | 05:03 |
| bawww | hello | 08:13 |
| bawww | does ubuntustudio have repositories that are more upto date for multimedia applications ? | 08:13 |
| bawww | or video editing software? | 08:13 |
| astraljava | bawww: Ubuntu Studio uses the same repositories than Ubuntu vanilla, so no external repos with more up-to-date applications, sorry. | 08:26 |
| mawst | Oh word. | 13:18 |
| mawst | Anyone know if theres a PC keyboard controllable virtual midi I can use with energyxt? | 13:18 |
| psidrum | anyone know if theres a gnome applet that connects to google bookmarks | 14:16 |
| psidrum | what does the Enable Nice option in Ubuntu Studio Controls mean? | 15:00 |
| VehementStar | http://en.wikipedia.org/wiki/Nice_(Unix) | 15:01 |
| VehementStar | That explains it better than I could attempt to right now :) | 15:02 |
| psidrum | ok thnks, whats the recommended nice for running music apps | 15:07 |
| VehementStar | depends on what else you have running on the machine | 15:07 |
| VehementStar | and how much power you really have | 15:07 |
| VehementStar | I wouldn't mess with it unless I needed to | 15:07 |
| psidrum | dual core, just wondering since im running a RT kernel and i set jack to RT and i get more xruns than when im using softmode in generic kernel | 15:08 |
| VehementStar | Are you seeing high utilization and load? | 15:09 |
| psidrum | no | 15:10 |
| VehementStar | I don't think nice will help you, then. | 15:10 |
| psidrum | ok | 15:10 |
| VehementStar | However, it wouldn't hurt to give it a shot. | 15:11 |
| VehementStar | you may be able to improve overall performance, but I doubt it. | 15:11 |
| VehementStar | the guys in #jack may be able to help, too | 15:11 |
| VehementStar | yay! | 15:17 |
| artisan | re | 19:40 |
| artisan | I had a strange experience the last 2 hours :) | 19:41 |
| artisan | I had blacklisted snd_hda_indel to have my ews88mt as primary soundcard with no interference | 19:41 |
| artisan | after reboot, I booted into -rt kernel for testing, I experiened horrable x-lags | 19:42 |
| artisan | after trying everything with nvidia drivers / compiz / metacity $whatever, I just un-blacklisted snd_hda_intel and | 19:42 |
| artisan | voila, all is back to normal. | 19:42 |
| artisan | it seems pulseaudio was hogging the system. | 19:42 |
| artisan | I suppose it had something to do with the intel card being selected in the pulse audio settings. | 19:43 |
| artisan | now wanting to switch those setting to the ews88mt I had to realize, that the hardware tab in sound preferences just lists no card at all | 19:44 |
| artisan | (should be three: onboard intel, ews88mt & bt848 tv card) | 19:44 |
| artisan | how do i start to debug here? | 19:45 |
| artisan | argl. this pulse audio will kill me one day .. garl | 20:53 |
| artisan | it is unbelievable. once pulse has a problem and doesn't start properly, the whole system lags like not see nbefore | 20:59 |
| artisan | htop shows nothing, but the whole X is lagging like hell | 20:59 |
| artisan | anyone here familiar with this pulseaudio mess? | 21:11 |
| Reaby | hi, where can i find expander ladspa plugin for ardour which has sidechain option | 21:37 |
| Reaby | i found only one expander - at tap dynamics, but it lacks the sidechain | 21:40 |
| holstein | hey Reaby | 21:52 |
| holstein | have you asked in #ardour ? | 21:52 |
| holstein | also, #opensourcemusicians | 21:53 |
| Reaby | just asked at #ardour | 21:53 |
| holstein | im sure there is one available | 21:53 |
| holstein | did you talk to las Reaby ? | 21:53 |
| Reaby | holstein: nope, i got some tips from #ardour | 22:12 |
| holstein | :) | 22:13 |
| artisan | ok, so far I got pulse using my 8 channel card as default output. is it possible with pulse to have apps on selected outputs? (like on channel 1&2 and not 3-8? | 22:21 |
| artisan | (actually pulse puts the mplayer putput to all 8 channels) | 22:21 |
| artisan | or is that definitive a job for jack? | 22:21 |
| holstein | JACK artisan | 22:24 |
| holstein | that should do it | 22:25 |
| holstein | route whatever you want really | 22:25 |
| artisan | holstein: ok, so, how do I integrate jack & pulse? (as there seems to be no real option to just uninstall pulse) | 22:27 |
| artisan | ok, just wile testing, i got for the first time ever multiple pulse outputs into jack and multiple system captures into pulse :) | 22:33 |
| artisan | looks good! | 22:33 |
| holstein | artisan: in my lucid set upt | 22:34 |
| holstein | up* | 22:34 |
| holstein | and the way it should work | 22:34 |
| holstein | pulse gets suspended when you start Qjackctl | 22:34 |
| holstein | if you want to use pulse through jack | 22:35 |
| holstein | you want... | 22:35 |
| artisan | funny though, that pulse has 8 sinks and sources and my ews88mt now has 12 captures and 10 playbacks (it is only 8 channels each in hw .. so I thought) | 22:35 |
| holstein | well | 22:35 |
| holstein | at least you want to read about | 22:36 |
| holstein | https://launchpad.net/kxstudio | 22:36 |
| artisan | yay, another approach :) | 22:36 |
| holstein | jack-pulse bridge i think? | 22:36 |
| holstein | i havent tried it yet | 22:36 |
| holstein | BUT i know it works | 22:36 |
| artisan | I have tried it a couple of times, but always pulse was on the wrong card, jack coughed somehow and went onto the same card. | 22:37 |
| artisan | suddenly with all my testing today, the multichannel card got card0 in alsa, and voila | 22:38 |
| artisan | now pulse-jack even works for me. | 22:38 |
| artisan | I never really understood why it didn't work :) | 22:38 |
| artisan | now it does and I won't touch it again, lol | 22:38 |
| artisan | kxstudio is a fork of ubuntustudio? | 22:38 |
| holstein | OH | 22:38 |
| holstein | thats a whole different thing actually | 22:38 |
| artisan | rly? | 22:39 |
| holstein | ive never heard about a sucessful 2 card test | 22:39 |
| artisan | ooops, you now what: | 22:39 |
| holstein | i got an 8 channel card too | 22:39 |
| artisan | external has 8, internal has 2 and tv card has 2 .. makes 12 | 22:39 |
| holstein | but i just use it with JACK sans pulse | 22:39 |
| holstein | artisan: nice :) | 22:39 |
| artisan | uh, funny :) | 22:40 |
| artisan | never knew it works | 22:40 |
| holstein | kxstudio is pretty sweet | 22:40 |
| artisan | (have the falk-t-x ppa there, must be jack2 :) | 22:40 |
| holstein | ckeck it out | 22:40 |
| holstein | and falktx hangs out in the ubuntu-devel channel and #opensourcmusicians | 22:40 |
| artisan | why is kxstudio not the same as ubuntustudio (lost track of dev efforts for ubuntustudio) | 22:41 |
| artisan | good to know! | 22:41 |
| holstein | kx is just his | 22:41 |
| holstein | AFAIK | 22:41 |
| artisan | ic, and he is in ubuntustudio as well? | 22:41 |
| holstein | falk's personal project | 22:41 |
| artisan | k | 22:41 |
| holstein | its lucid based | 22:41 |
| holstein | BUT | 22:41 |
| holstein | you can use his repos and cutom packages | 22:41 |
| holstein | with lucid | 22:42 |
| artisan | so I do, nice to get the latest development nicely packaged for testing :) | 22:42 |
| holstein | yup | 22:43 |
| holstein | i havent done it yet | 22:43 |
| holstein | BUT lots of folks say its solid | 22:43 |
| holstein | and the guy is really on the ball it seems | 22:43 |
| artisan | well, it looks solid .. 12 in 10 out .. o.O | 22:44 |
| artisan | a thing everybody always said would never work. | 22:44 |
| artisan | but hey, I expect samplerate problems :) | 22:44 |
| artisan | and no, there is no output on the onboard card :) | 22:45 |
| holstein | thats awesome | 22:45 |
| holstein | you should check out the wiki over there at #opensourcemusicians | 22:45 |
| holstein | if you feel like sharing that setup | 22:45 |
| artisan | hm, nah, actually there is *no* sound on the internal | 22:46 |
| holstein | thats supppose to be the output card? | 22:46 |
| artisan | nope, supposed output card is the 8 channel. which works | 22:47 |
| holstein | OH | 22:47 |
| holstein | i gotcha | 22:47 |
| holstein | 8 out | 22:47 |
| artisan | but I was just curious and connected sound to the left over 12 channels | 22:47 |
| holstein | i got 8 in | 22:47 |
| artisan | (9-12) | 22:47 |
| artisan | yeah, and 8 in as well | 22:48 |
| holstein | ok | 22:48 |
| artisan | but there is actually 12 in in qjackctl and 10 out, which is funny | 22:48 |
| holstein | maybe some spidif out it doesnt know about? | 22:48 |
| artisan | hm, could be | 22:49 |
| artisan | there are supposed to be some digital ins and outs I seem to have forgotten (and jack never showed them up before as well) | 22:51 |
| holstein | what unit? | 22:51 |
| artisan | ews88mt from terratec | 22:51 |
| holstein | good to know | 22:52 |
| holstein | i bet you can get a used one now pretty reasonalbe | 22:53 |
| holstein | whats the latency like? | 22:53 |
| holstein | decent? | 22:53 |
| artisan | yeah, now I remember whats the tricky part with that setup .. | 22:56 |
| artisan | you can't easily restart jack, as pulse freaks out | 22:56 |
| holstein | with that custom distro | 22:56 |
| holstein | KXstudio | 22:57 |
| holstein | jackk is running at login | 22:57 |
| artisan | yeah, here too, but wanna change frames? reboot .. | 22:57 |
| artisan | hmm | 22:57 |
| artisan | I was working with 16ms latency, just wanted to test with 2ms | 22:58 |
| holstein | not bad | 22:58 |
| artisan | and now, with a freaking pulse, X isnt responding properly. hehe, i was trying all afternoon finding out why my system lags like hell, until i discovered pulse is the source for that | 22:59 |
| artisan | holstein: is there only reboot as a way to restart sound services in that kind of setup? | 23:00 |
| holstein | no | 23:00 |
| holstein | theres a restart.d or seomthing | 23:00 |
| artisan | hmm | 23:01 |
| holstein | i cant remember though | 23:01 |
| holstein | OH | 23:01 |
| holstein | i used jack_control -something | 23:01 |
| holstein | that didnt get pulse though | 23:01 |
| artisan | ah | 23:01 |
| artisan | jack_control is a very good hint! thx | 23:02 |
| * holstein cant remember.... | 23:02 | |
| artisan | hmm, dbus: jack server could not be started .. | 23:03 |
| artisan | *sigh* | 23:03 |
| holstein | hmmmm | 23:03 |
| holstein | no other errors? | 23:03 |
| holstein | can you kill it | 23:03 |
| holstein | and start is with qjackctl in the terminal | 23:04 |
| holstein | OR look that the 'massages' window | 23:04 |
| holstein | in Qjack? | 23:04 |
| artisan | 00:04:49.338 D-BUS: JACK server could not be started. Sorry | 23:05 |
| artisan | thats all | 23:05 |
| holstein | hmmm | 23:06 |
| holstein | sudo killall jackd ? | 23:06 |
| holstein | maybe something is still hanging on | 23:06 |
| holstein | OH | 23:06 |
| holstein | wait | 23:06 |
| holstein | you changes settings right? | 23:06 |
| holstein | i bet thats it | 23:07 |
| artisan | no jackd running, no pulse running. | 23:07 |
| artisan | new started qjackctl, yields the error above .. | 23:07 |
| holstein | what changes did you make? | 23:08 |
| artisan | just swithc from 256 frames/period to 32 | 23:08 |
| artisan | but, I believe it is a pulse issue | 23:08 |
| artisan | someone is sitting on alsa | 23:08 |
| artisan | that must be pulse | 23:08 |
| artisan | E: module.c: Failed to load module "module-jack-sink" (argument: "channels=8"): initialization failed. | 23:10 |
| artisan | thats what pulse sez | 23:10 |
| artisan | because jack isnt running | 23:10 |
| artisan | jack i cant start, because there is something borked. | 23:10 |
| artisan | no sound apps running so far | 23:10 |
| holstein | doesnt seem to want all your 8 channels now | 23:11 |
| holstein | hmmm | 23:11 |
| artisan | funny thouhg, starting jackd from cli works. | 23:13 |
| artisan | and pulse just started itself. | 23:14 |
| artisan | hm, to much automagic for me :) | 23:14 |
| artisan | holstein: ever tried different realtime kernels? https://launchpad.net/~abogani/+archive/ppa/ | 23:35 |
| artisan | so, does one want lowlatency or realtime .. hmmmmm | 23:35 |
| holstein | i just use the RT one | 23:36 |
| holstein | ive used other distro's RT kernels | 23:36 |
| artisan | yey, I 'll try alesio's :) | 23:38 |
| rlameiro | artisan: it depends what you want to do with it | 23:38 |
| rlameiro | if you run a RT kernel on you laptop you will dry much faster the battery | 23:38 |
| artisan | usually i want to have a decent low latency for audio. | 23:38 |
| artisan | and on a lappi suspend would be fantastic. | 23:39 |
| rlameiro | but for what? f | 23:39 |
| artisan | dj mixing | 23:39 |
| rlameiro | ok | 23:39 |
| rlameiro | so you need RT maybe | 23:39 |
| artisan | to prevent xruns .. | 23:39 |
| artisan | why is rt using more battery? | 23:40 |
| holstein | you dont really need low latency though | 23:40 |
| holstein | for DJ'ing | 23:40 |
| rlameiro | well to prevent XRUNS low dow you latency | 23:40 |
| rlameiro | up your latency sorry | 23:40 |
| rlameiro | you dont need 8 ms latency for djing | 23:40 |
| holstein | if you dont need it, i wouldnt push it | 23:41 |
| holstein | yeah | 23:41 |
| rlameiro | 20 ms is ok | 23:41 |
| holstein | 60+ even | 23:41 |
| holstein | who cares | 23:41 |
| holstein | your not needing to sync up with anything | 23:41 |
| rlameiro | yeah, you are not worring if a frame drops or not, it doesnt matter for that job | 23:41 |
| rlameiro | and also RT kernel uses more power , because it is contantly assigning task and scheduling for audio usage or other usages | 23:42 |
| rlameiro | RT is for all the system :D | 23:42 |
| artisan | well, but to use mixxx properly you need jack, jack without rt usually sucks alot | 23:48 |
| rlameiro | artisan: no it doesn | 23:48 |
| rlameiro | it works great with the generic kernel in 10.04 | 23:48 |
| artisan | never experienced jack without rt running without xruns .. | 23:48 |
| artisan | just tested on my t41p | 23:48 |
| rlameiro | i use it with ardour plus firewire sound interface plus Puredta and it works ok :D | 23:49 |
| artisan | hm | 23:49 |
| artisan | maybe the cpu with 1.7ghz single core pentium m isn't decent enough anymore for that kind of tasks :) | 23:49 |
| rlameiro | the last generic kernel on ubuntu, actually have some rt capabilities, or elese you couldnt use jack :D | 23:49 |
| rlameiro | and you configure jack at install time for that :D | 23:50 |
| rlameiro | artisan, maybe you need to increase the latency | 23:50 |
| artisan | rlameiro: hm, cant remember to have jack configured. otoh it was a dist upgrade .. | 23:51 |
| rlameiro | either the frame/period or period buffer | 23:51 |
| rlameiro | well, it should work | 23:51 |
| artisan | Cannot lock down memory area (Cannot allocate memory) | 23:52 |
| artisan | 00:52:27.670 XRUN callback (1). | 23:52 |
| artisan | alsa_driver_xrun_recovery | 23:52 |
| artisan | **** alsa_pcm: xrun of at least 34.126 msecs | 23:52 |
| artisan | just after starting jack with qjackctl | 23:52 |
| rlameiro | hummm | 23:53 |
| holstein | thats a nasty one too | 23:53 |
| artisan | 512 frames, 2 periods/buffer | 23:53 |
| artisan | ack | 23:53 |
| rlameiro | well the settings did changed from 9.10 to 10.4 | 23:54 |
| rlameiro | the limits.conf is in diferent place for audio | 23:54 |
| artisan | hm, so do you think a pentium M 1.7ghz should be enough for mixxx/jackd without RT ? | 23:54 |
| artisan | oh. /etc/security/limits.conf or another one? | 23:54 |
| rlameiro | it changed in this release | 23:55 |
| rlameiro | let me digg up the help wiki | 23:55 |
| rlameiro | https://help.ubuntu.com/community/UbuntuStudioPreparation | 23:55 |
| rlameiro | thre is a note somewhere about it | 23:55 |
| artisan | etc/security/limits.d/audio.conf | 23:56 |
| artisan | hm | 23:56 |
| rlameiro | maybe it didnt changed it on the dist upgrade | 23:57 |
| rlameiro | or you didnt accept the window that usualy appears on install time | 23:57 |
| artisan | ack, it just took the settings from the former limits.conf | 23:57 |
| rlameiro | well put the buffer at 1024 :D | 23:59 |
| rlameiro | its my normal usage for playing stuff | 23:59 |
