*** hyades has joined #timvideos16:36
hyadeshello16:40
rihnapstorhyades:  hi16:42
hyadesI wished to take part in gsoc.Had a discussion few days back about timvideos in general. Wanted information about the the tasks of improvements in flumotion & gst-switch16:42
hyadeshad a brief look into the codes of both of them.16:43
rihnapstorhyades: do you have instance of streaming video running  on your server ?16:44
hyadesDue to some hardware constraints currently, i dont have it running it now. Any online link  available?16:46
rihnapstorhyades: thats what I am looking for . :) I think hyades  its a weekend so mentors are offline .I am struggle to get my instance working.16:48
rihnapstorbtw flumotion and gst-switch is an hardware project ?16:48
CarlFKrihnapstor: here16:49
CarlFK flumotion and gst-switch are software16:50
CarlFKhdmi2usb is hardware16:50
hyadesyup16:50
hyadeshow do u test it on own machine??16:52
hyadesAre'nt the sources of the streams configured for specific input cameras?16:53
rihnapstorCarlFK: bottstrap scrit ''make serve" fails to download ez_setup !  traceback here http://dpaste.com/1066504/16:58
tpbTitle: dpaste: #1066504: timvideo bootstrap fails (at dpaste.com)16:58
CarlFKrihnapstor: where did bottstrap come from?16:59
CarlFKand yeah, I am unfamiliar with what is where.  I have just worked in the same room as Tim, not actually worked on the same code17:00
rihnapstorCarlFK: The "make file" command successfully made virtual stack for streaming-system frontend code, but it fails to download some dependencies.17:01
CarlFKhyades: there is no reason everything can't run on the same box17:01
rihnapstorCarlFK:  here is the link of my traceback http://dpaste.com/1066504/17:02
tpbTitle: dpaste: #1066504: timvideo bootstrap fails (at dpaste.com)17:02
hyadesit can if i tweak the input sources in gstreamer, but i can never test performance related issues17:02
CarlFKrihnapstor: what do I run to reproduce that?17:02
hyadestry installing pypi through easy_install17:03
rihnapstorok17:03
CarlFKinstalling pypi ?17:04
hyadesCarlFK: what part of the project do you work on??17:05
CarlFKhyades: currently none17:07
hyadesk17:07
CarlFKI do the video *recording* for pycon17:08
CarlFKand Tim hooks into that system as a video source17:08
hyadesTim is mithro?17:08
hyadesright?17:08
CarlFKI just give him admin access to the boxes, trust he wont break anything, and streaming happens17:08
CarlFKyes17:08
hyadesafk?17:08
CarlFKyeah, it is 3am in Australia where he lives17:09
hyadesok ok :)17:10
rihnapstorohh CarlFK  then mithro is asleep :)17:10
hyadesat the recording end the setup is same as mentioned in some of the diagrams or is that thing proposed?17:12
CarlFKI use DVswitch, which can stream ntsc/pal dv over tcp - connect to port 2000, get a 30mbs sream of dv frames17:18
CarlFKtim wrote a gstreamer source to manage that connection17:18
rihnapstorCarlFK: what can you say from my traceback ?17:20
hyadesand how many end clients/ servers are present?17:20
hyadesin this system?17:20
CarlFKrihnapstor: nothing new .. I need steps starting at step 117:20
CarlFKhyades: pycon had 400 viewers at one time I think17:21
hyadesand this had how many servers?17:21
CarlFKrihnapstor: your trace back should start with a prompt so we can see what dir you are in and what command/parameters you did17:22
CarlFKhyades:  no idea about servers.  but the processes run in VMs, so the concept of 1 server gets a little fuzzy17:23
rihnapstorCarlFK: ok ,posting traceback again.I think its python compatibility  issue.requires python2.6 ? really ?17:24
CarlFKhyades: I wouldn't worry about testing performance until there are docs showing how to set things up17:24
rihnapstorCarlFK:  new traceback here http://dpaste.com/1066526/17:25
tpbTitle: dpaste: #1066526 (at dpaste.com)17:25
hyadesi went through some of the gstreamer pipeline elements, and I dont think much can be improved in this part. Only interaction if required with other things will require some extra elements.17:26
*** skay has joined #timvideos17:28
CarlFKhyades: personally, I want to see setup docs17:31
hyadesso which area requires most attention apart from the hardware part?17:32
rihnapstorfor development version setup docs  https://github.com/timvideos/streaming-system17:33
tpbTitle: timvideos/streaming-system · GitHub (at github.com)17:33
rihnapstorCarlFK:17:33
CarlFKrihnapstor: have you actually done it?17:35
rihnapstordone what CarlFK  ?17:35
CarlFKsetup a stream17:36
CarlFKwhat you pointed me do is not "how to set up the streaming system"17:37
CarlFKI don't think such a document exists yet17:37
skayhi all, I'm going to lurk here, though I am busy at hte moment with a last minute assignment17:38
skaybut in way of intro, I've been to a few pycons and other conferences where I've seen tim running streaming stuff17:38
CarlFKI know how to setup/configure the cameras and vga converter sources to create .dv files that get encoded and uploaded to youtube.  I have no idea how to hook up the stream stuff17:39
rihnapstorCarlFK:  sorry , here is the Initial config for setting up https://github.com/timvideos/streaming-system/tree/master/website17:39
tpb<http://ln-s.net/-2c1> (at github.com)17:39
skayand I'm interested in whether this can happen at an upcoming conference. I do not have experience deploying the system for a conference17:39
CarlFKrihnapstor: that's better.  have you done it yourself ?17:39
skayI've pinged the organizers to see if they are open to having volunteers show up to set up streaming, and they are intrigued, but I don't know if whoever is doing av will be doing anything that would work with streaming17:41
skayat any rate, if they are doing anything plausible, and any of the gsoc folks find it easy to get to Austin for scipy, maybe it would be a good trial run?17:42
skayanyway, I need to go afk17:42
rihnapstoryeah.cloned but stuck on "make server" command.17:42
CarlFKrihnapstor: on Ubuntu 11.10 oneiric it seems to work - I got to "You just installed Django's auth system, which means you don't have any superusers defined.  Would you like to create one now? (yes/no): "17:43

hyadesthe django server18:16
rihnapstorexactly CarlFK  its fails with permission denied error18:16
CarlFKthere we go.18:17
CarlFKone of you should open an issue about that18:17
rihnapstorCarlFK: not so soon ,keep trying18:17
hyadesis it a git related issue that you are getting?18:18
CarlFKI would call it a permissions problem18:20
CarlFKbut as long as there is a problem, it should be reported18:20
CarlFKlet the person who handles the problem figure out the details18:20
hyadeshave u setup github keys properly?18:22
CarlFKme?18:23
rihnapstorCarlFK: check out your .ssh directory18:24
hyadesya18:24
CarlFKyou are missing the point.  no where does it say I should be setting up github keys.18:25
CarlFKand I doubt that is really necessary.  I can guess what happened, but that doesn't matter.18:27
hyadeszip file doesnt work also????18:27
CarlFKif the docs are wrong, you should open an issue.18:27
hyadeshas anyone setup gst-switch?18:49
CarlFKI don't think gst-switch has ever been used in production18:50
CarlFKuntill that happens I am not touching it18:51
hyadesalways dv switch?18:51
CarlFKyeah - I have been using dvswitch for about 5 years18:52
hyadesooh18:52
CarlFKlooking forward to gst-switch - but don't have time to hack on it until it is at least functional18:52
hyadeswanted to know how to test gst-switch19:31
hyadesi installed it, now what ?19:32
hyadesits listening on 3k,4k,5k ports. How do i connect to them?19:34
CarlFKwhat do you want to use as an input?19:37
hyadesseems to be some stream19:39
CarlFKUm.. I was expecting web cam, file, or something at generates a test pattern19:40
hyadessay webcam and a file19:42

CarlFKI am going to make some assumptions and skip ahead.. please open an issue about lack of docs19:43

rihnapstorhyades:  what is the git url you cloned into your computer ?19:55
rihnapstorand it worked fr you with no errors19:55
rihnapstorwhat is the git url  for timvideos you used?19:56
hyadesu want which package?19:58

rihnapstorok thanks20:03
CarlFKthats all in the issue, right? :)20:06
hyadeshaha20:06
hyadesCarlFK : in the dvswitch how do i view a source?20:10
*** rihnapstor has quit IRC20:11
*** parx has joined #timvideos20:11
CarlFKhyades: you should see a thumb.. but that kinda tells me you haven't connected a source yet.. here is what I recomend:20:12
CarlFKgit clone git://github.com/CarlFK/dvsmon.git20:14
CarlFKcd dvsmon20:14
CarlFK~/dvsmon$ ./testit.sh20:14
CarlFKthat should give you a gui with lots of "run" buttons.  start from the top, click one, wait a sec or 2 for it to get up and running, repeat20:15
hyadeswx is what module?20:15
CarlFKoh yeah...20:16
CarlFKsec...20:16
CarlFKsudo apt-get install python-wxgtk2.820:18
CarlFKI thinik...20:18
CarlFKat least that's what I have in dvsmon/debian/control  but I am not sure I ever have used the package.20:20
hyadessec..installing20:20
hyades.20:21
CarlFKdvsmon is great for testing dvswitch and I use it for production, but it is kinda daunting and has had issues over the years, like some problem with wx and ubuntu's desktop manager or something that I could never pin down - Tim fixed it by rewriting a big chunk20:22
CarlFKthere are a few ways the dvswitch components are managed - all of them have some flavor of problem ;/20:23
hyadesit gives an error20:24
hyadeswhat hostname and port?20:24

CarlFKnope21:23
CarlFKunless your webcam is a DV device21:23
CarlFKwhich there are only like 3 in the worlds21:23
hyadeshence the need for gst-switch21:23
CarlFKdon;t spend too much time on dvswitch - other than it makes a handy source for the streaming stack21:23
CarlFKyeah - gst-switch will do "everything"21:24
CarlFKI know the streaming stack is ready - I have seen it work twice .. maybe 3 times21:25
CarlFKbut it has lots of parts that all need to be setup21:25
CarlFKand from what I can tell there the docs don't even come close to telling anyone how to set up anything21:26
CarlFKso you have dvswitch running, it would be great if you could figure out how to setup the stuff that goes between it and a browser21:26
CarlFKso you open firefox on the same box, hit http://localhost/room1 and see the 1/2 test patterns21:27
CarlFKgetting that to happen would be great, and showing someone a doc that they can use to get it going is the real goal21:28
