RzRdl9pf, rdp10:16
RzRdl9pf, there is no network transparency in wl10:17
RzRdl9pf, so RDP is the fallback option10:17
RzRdl9pf, you need to use RDP backend , I am not sure you can use several at the same time10:17
RzRbut but but...10:18
RzRhttps://blogs.s-osg.org/wow-wayland-over-wire/10:18
RzRdl9pf, is this helpful to you ?10:19
dl9pfRzR: looking ...10:23
dl9pfRzR: got a pointer/link for the rdp backend ?10:24
RzRI think it's part of package10:24
RzR weston --backend=rdp-backend.so --width=1024 --height=768 --rdp-tls-cert=/root/tizen.crt --rdp-tls-key=/root/tizen.key10:25
RzRI had this in my notes10:26
dl9pfcool ... hmm, so I'd craft a weston ini . are the certs needed ?10:26

CTtpollardgunnarx: did you get a tattoo in the end before you left?11:08
gunnarxlol.  Yeah I woke up with a dragon tattoo on my back...11:08
CTtpollardSounds like quite the night11:10
gunnarxtbh, after this week all I wanted to do was sleep11:11
CTtpollardI still want to sleep, long week indeed11:12
gunnarxI went a 2-3 hours early to the airport, had nothing to do.  then found out the flight was delayed 3 hours...11:13
gunnarxso close to 7 hours at SFO before we took off, and then of course missed connections etc.11:13
gunnarxI figured out I got home exactly 24 hours after arriving at SFO.  without my luggage of course.  I'm getting used to it.  Air travel... :-/11:15
dl9pfleon-anavi: did you try with smack on rpi?11:24
CTtpollardgunnarx: yeh our original flight from SF - Dublin got cancelled, so we had a 4 hour wait in Dublin for the Manchester connection. In a tiny room, with a vending machine for amusement11:26
gunnarxoh lovely11:26
CTtpollardBut sucks about your luggage, I always fear that11:26
leon-anavihi dl9pf no, I have built and booted a version with Anton's and yours patch this morning.11:28
gunnarxCTtpollard, it was all due to the connection confusion and several screwups despite rebooking, they managed to finally put me on waiting list for the last flight out but failed to rebook/forward my luggage11:28
gunnarxI got it next day though11:28
leon-anavidl9pf, Weston was working fine now. The version of OSTree was v2016.11 because I checked out the branch from Gerrit11:28
leon-anavidl9pf, After merging it with the top of the master the version should be 2016.12 because of my patch from the previous day.11:29
dl9pfleon-anavi: yep, things look fine. we likely need to check smack11:29
leon-anavidl9pf, I am working on the documentation. I am preparing a simple HTML header, footer and css for pandoc.11:30
dl9pfleon-anavi: very good11:30
leon-anaviI am writing the tutorials as md and I am using pandoc to export them to HTML and PDF.11:30
dl9pfok, so we'd need pandoc in jenkins. ok, will add11:30
leon-anavipandoc is capable of merging several md files and after that exporting the whole thing into HTML (or PDF).11:31
dl9pfshoot me the cmdlines to create html and pdf , I can add a ci job over the weekend11:31
leon-anaviok, perfect11:31
leon-anaviwhere are you going to host the generated HTML files for the documentation?11:31
dl9pfwell, jenkins can only write out to download.automotivelinux.org ...11:32
dl9pfso there to start with11:32
leon-anaviok11:34
leon-anavithis sounds as a good start11:34
leon-anavilater today I will post details about my progress in the mailing list11:34
RzRdl9pf, it  depends on your RDP client IIRC11:46
Mathieu_DuHey o/12:04
Mathieu_DuStill no one around to discuss AudioManager ?12:05
CTtpollardMathieu_Du: you're best of taking it to the audiomanager mailing list, the maintainers don't hang around here :)12:06
CTtpollard*off12:06
Mathieu_DuCTtpollard, oh OK!12:07
Mathieu_DuI assumed I would get lucky at some point, too bad12:07
CTtpollardI mean, there will be folks here with AM experience12:08
*** dirkb has left #automotive12:38
radiofreedoes anyone have screenshots of the new hmi?12:53
* radiofree wonders if it's as nice as the AGL or neptune uis12:54

*** jobol has quit IRC12:58
radiofreeah13:00
radiofreeit's certainly nicer than the last one13:00
*** tylercampbell has joined #automotive13:01
*** kooltux_ has joined #automotive13:01
CTtpollardit makes better use of the ivi-extension13:02
radiofreelooks a lot nicer as well13:05
radiofreei remember a colleague commented "i see you're using the GDP from the 1990's" when he saw me using the old one ;)13:05

reinarHi #automotive! Anyone familiar with AVB used for streaming video (more exactly, camera views to head unit)?13:53
*** JordonWu_ has quit IRC14:00
gunnarxreinar, familiar in what way?14:02
reinargunnarx: to give few hints about how transmitting h264 video over AVB is working. Or point in some right direction, if stable implementation is available in AGL14:08
gunnarxI can't imagine the AVB standard requires a particular video encoding...14:10
gunnarxprevious work in GENIVI (and everywhere else in open source world) have always looked toward: https://github.com/AVnu/Open-AVB14:10
gunnarxI guess you know it already...14:10
gunnarxAs an alternative you might want to track this project https://github.com/GENIVI/slotted_udp.  It's a matter of evaluation/research but interesting to see where it leads, since full AVB is a quite complex beast14:12
reinarwell... it's part of the problem. I also used to think so, but the payload format maybe is depending on the codec14:16
reinarhttp://grouper.ieee.org/groups/1722/contributions/2011/1722a-dolsen-avtp-video-v2.pdf14:16
reinarand as far as I understand, avtp pipeline from open-avb implements some h264-related logic while processing those avtp packets (though the protocol is specified as RTP, but why it should care then?)14:22
reinarso I was asking if someone has better picture and understanding14:22
gunnarxhmm... as I said a complex beast :)14:22
reinarhttps://github.com/AVnu/Open-AVB/tree/master/lib/avtp_pipeline/map_h26414:22
gunnarxWell now that I know what your picture is, it's easier to answer that:  No I do not have a better understanding.14:23
reinarthanks anyway :)14:23
gunnarxlooks like I was wrong - guess they have included some opinion on the codec and how it should be handled14:24
gunnarxyou're welcome14:24
reinarI'm trying to grasp if I could get frames, cut AVTP headers and reassemble this in RTP or mpegts stream that I could pass further14:25

furyCurious to know, I'm new at Linux for embedded systems, what's a good way to be able to do dynamic volume-based & speed-based EQ per speaker?16:47
furyLike, is there an SoC that has a ton of outputs that I can send a different filtered signal to each, or does it require a separate DSP chip?16:49

dl9pffury: use master. was not fully ready for blowfish.20:14
furyah. makes sense. but still having that problem where I can't start up the demo :(20:15
furyunless that's been fixed within the last day or two20:16
*** jobol has joined #automotive20:36
dl9pfis it failing with some dbus message and a segfault ?20:36
furyyeah, something about dbus20:38
furySPEC-270 on the jira20:38
dl9pfyep. if SPEC-270 is not yet fixed, that is the problem.20:39
furycool, seems like i'm stuck i guess :D master doesn't finish booting up on wandboard (stuck at splash screen, i can get to a terminal via ctrl+alt+fsomething but dunno where to look from there)...i get that dbus error on pi and porter from latest master build...because of the older graphics drivers not being available from renesas, i can't jump back in time20:43
furyand build an older version for porter20:43
furyi wish irccloud would just stop me from typing instead of auto splitting lines, that looks ugly20:43
dl9pffury: renesas added20:43
dl9pfthe old gfx drivers back on the homepage20:44
furyoh, sweet20:44
dl9pfrecheck their dl page20:44
dl9pfthey added the zip back for us20:44
dl9pfjust today20:44
dl9pfSee https://www.renesas.com/en-eu/solutions/automotive/rcar-demoboard.html20:44
furylicenses are fun... i wonder why it is they can't just allow the drivers to be included and run unlimited...20:44
dl9pfthere are not 2 download links20:45
dl9pffury: no comment ;)20:45
dl9pfs/not/now/g20:45
furyok sounds good. so which tag/branch do i check out for that demo to work, 2.0.0 2.0.1 2.0.2?20:46
*** waltminer has joined #automotive20:48
furysorry for taking up so much time with noob questions the last few days :D i'm just really excited at the idea, open software running all the things, less wheels for me to reinvent (well, except the ones i need to reinvent one last time and throw into AGL)20:48
dl9pfI'd use latest blowfish branch, so just:20:48
dl9pf  $ repo init -b blowfish -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo20:48
dl9pf  $ repo sync20:48
furyok cool20:49
furythat MacBook Pro getting quite a workout with the compiles the last few days lol20:49
furyseriously considering spending my computer replacement budget on a massive 48 core server if i'm gonna be doing too many more of these :D20:52
*** jlrmagnus has quit IRC20:55
dl9pffury ... wait a sec20:57
dl9pfprobably a mistake20:58
furywouldn't be my first one :D20:58
dl9pfnot you ... just verifying the blowfish branch ... continue my bad20:59
furyoh ok20:59
furyi am somewhat familiar with git as i've been using it at work with the software team (2-3 guys), is what AGL uses basically a bunch of git repos? that's what the repo sync looks like to me anyway21:00
*** jobol has quit IRC21:01
*** jlrmagnus has joined #automotive21:03
dl9pf5 from AGL + 8 or 9 external repos21:05
dl9pfcombined21:05
furysweet21:05
furyso i just keep getting forwarded back to the download page when i try to download the older renesas drivers :D21:12
furyseems like it's not staying signed in or something21:13
furyi love web browsers. it amazes me that they ever work at all21:13
furybut sometimes, man, simplest stuff goes wrong21:14
JEEBnever forget how much people can get web services wrong, too :)21:18
JEEB"oh, you had a session? no, not found."21:18
*** nisha has joined #automotive21:30
furyyeah, mine did that not too long ago when the ram disk got full and it could no longer write anything new to /tmp/sessions21:32
furysomeone found out they could simply create new sessions as a DDoS on the server if they did it enough, created hundreds of thousands21:34
furyone of these days i'll learn how to admin a server :D21:34
furybeen doing it for like 15 years21:34

furyhmm. i may have been compiling on the wrong computer for the last few days :P i thought the macbook pro quad core i7 2.3ghz, which i installed an SSD into, would be faster, so i partitioned off 200 gb for linux and been running there. compiling a build for the porter there. but 10 minutes later started a compile on a thinkpad with a spinning hard drive but a21:54
furyquad core i7 2.6ghz, it's about to overtake21:54
furycompiling for the wandboard21:54
