*** tpb has joined #timvideos00:00
mithropk__: ping?00:30
mithropk__: we generally only load onto the cypress RAM rather then FLASH, so you can just power cycle the board to go back to the Atlys firmware00:31
*** tpb has joined #timvideos01:02
puckAh, so that's why the board keeps on forgetting the firmware!  ;)01:39
*** Super_Roach is now known as SuperRoach01:52
mithropuck: At the moment we don't have a good story for writing to the Cypress FLASH yet02:21
mithroNickB_: ping?02:23
mithropuck: we really need to investigate a FOSS firmware to load onto the Atlys board which supports flashing the Xilinx02:24
mithropuck: there are a bunch out there, we just need to figure it out :(02:25
puckE_NOTIME huh?02:26
mithropuck: yeah02:32
mithroso the question is, do we have enough mentors to do GSoC?02:33
puckNot I02:50
mithrolukejohn_ / NickB_: thoughts?03:10
mithrohyades: ping?03:10
mithro~seen iiie03:11
tpbmithro: iiie was last seen in #timvideos 4 days, 3 hours, 37 minutes, and 54 seconds ago: <iiie> update does a database update and doesn't run signals either03:11
lukejohn_mithro: sorry been away from desktop, thoughts on what?03:24
mithrolukejohn_: Google Summer of Code, trying to figure out if we have people who are willing to be mentors03:24
lukejohn_i'm uncertain how gsoc works, but i can't imagine you'll have trouble finding people willing to give advice to people coding on the open source video conferencing stack.03:30
lukejohn_Though after reading https://code.google.com/p/google-summer-of-code/wiki/Mentors ,  it looks like it would be tricky as i imagine most gsoc student are in US timezones and would struggle to get timely responses to irc queries.03:32
tpb<http://ln-s.net/AsSG> (at code.google.com)03:32
mithrolukejohn_: so a mentor needs to be available for a minimum of ~10ish hours a week to work with the student03:37
mithroI need 3 other mentors minimum03:38
mithrothaytan: I'm assuming you don't have the time03:38
CarlFK ~10ish hours a week is 2h / day m-f - that seems a bit much03:40
lukejohn_mithro: We've got our local lug agm tonight so I will ask the lca14 av team about availability.03:41
mithroCarlFK: good students obviously need less time03:42
mithrobut I would say I was doing at least 1 hour a day (during the week) but sometimes up to 3 or 403:42
lukejohn_also just a heads up, the lca14 av team may be involved with av for the edge of the web (EOTW) conference this year. (i haven't actually spoken to the av team about this, I just bumped into the organiser late last week)03:44
lukejohn_is there a wiki/git_repo/some_other_thing that is documenting what events are being streamed by who and with what stack03:44
CarlFKoh my :)03:46
CarlFKlukejohn_: there is a goog calendar of events for .. um.. event's mithro has some ties to .. not sure how to define it03:48
CarlFKmithro: use gst-switch somewhere!!! :p03:48
CarlFKwouter wants to start using it too - but like me, doesn't want to be the first03:49
mithroI need to submit an application to GSoC over the next 24-48 hours03:49
mithroCarlFK: yeah I know03:49
mithrowhois wouter?03:49
CarlFKcurrent dvswitch project lead, and lead of video for fordem03:50
CarlFKfosdem did 22 rooms a few weeks ago.  with 22 twinpacts.  and wants to use something else next year.03:51
mithroCarlFK: did I tell you about snowmix?04:00
CarlFKmithro: don't think so04:00
mithroIt looks a lot like gst-switch04:01
tpbTitle: Snowmix | Free Audio & Video software downloads at SourceForge.net (at sourceforge.net)04:01
mithroSnowmix is a video mixer tool for mixing live and recorded video and audio feeds. It supports clipping, scaling and transparent overlay of video, png graphics and text. It supports animation of video, images and texts through native commands changing scale, placement, transparency and rotation. Animation and actions can also be controlled through native04:01
mithroscripting and an embedded Tcl interpreter. Snowmix is designed for control over low bandwidth links and can work as a standalone CLI based program. Control over both CLI and a TCP connections. Live and recorded video feeds can be fed to the mixer via GStreamer pipelines. Output can be accessed through GStreamer pipelines.04:01
CarlFKI am skeptical04:02
CarlFKat fosdem someone was trying to tell me vlc could be used in place of DVswitch04:02
CarlFK"because it can do pic n pic."04:03
CarlFKI didn't feel like pursuing that conversation04:03
CarlFKpretty sure the person had never run DVswitch.04:04
*** pk__ has quit IRC04:06
mithroCarlFK: snowmix seems to have been actually used in production settings04:57
mithroCarlFK: but it doesn't appear to be publicly developed04:57
CarlFKScreenshot 3 / 5   Snapshot of the GUI based control application Snowcub04:59
CarlFKi worry that it isn't something that some volunteer can figure out basic operation in 5 min05:00
lukejohn_mithro: the linuxconfau2014 youtube account has been terminated, who should I talk to about this?05:06
CarlFKlukejohn_: woa.  any idea why?05:07
lukejohn_CarlFK: no idea, just spoke to Steve Walsh and it sounds like mithro is aware of the problem.05:08
mithrolukejohn_: I'm on it05:16
mithrolukejohn_: who is the dvswitch management software developer again?05:28
lukejohn_mithro: wouter? I think you may have me confused with CarlFK though. (luke john is from perth lca)05:30
mithrolukejohn_: the one lca2014 used, starts with an e - restarts dvswitch when it crashes and stuff?05:31
lukejohn_my mistake leon wright (techman83) and jason nicholls (nimm) would be the project leads05:32

pk__Gsoc times :)06:17
* pk__ feels nostalgic :)06:17
mithropk__: you where a GSoC student or mentor?06:20
mithro~seen Sewar06:21
tpbmithro: Sewar was last seen in #timvideos 18 weeks, 0 days, 3 hours, 19 minutes, and 31 seconds ago: <Sewar> CarlFK, nice06:21
pk__student several times :)06:21
pk__upto three projects in a single year...lol06:22
pk__mithro: http://people.videolan.org/~pk06:24
tpbTitle: Pankaj Yadav's WebHome (at people.videolan.org)06:24
mithropk__: just a tip for that site, you should be putting spaces after both full stops and commas -- IE  "abc. Test" not "abc.Test"06:26
pk__although i have not visited the site myself in last 3 years :)06:27
*** pk__ has quit IRC06:40
*** pk__ has joined #timvideos06:40
pk__i tried on prebuild on atlys yesterday06:42
pk__made mcs of the bit file and loaded to the flash of atlys06:42
pk__then hardware was running properly..i could see the test pattern on my tv06:43
pk__but on computer i ran ubuntu and then programmed the cypress chip06:43
pk__and i could see that an UVC device was shown /dev/video106:44
pk__but when i played it via vlc then no video :(06:44
mithropk__: the test pattern appears before you flash the Atlys bit file07:34
pk__why would it appear before ?07:34
pk__i connected my set top box to HDMI IN of atlys07:35
pk__and tv to hdmi out07:35
pk__then i started atlys07:35
pk__since the bit file is written on flash so it loads the bit file automatically07:35
pk__then test pattern appears on tv07:36
pk__then i press some button and video  came on tv07:36
pk__so basically hardware is working okay07:36
pk__then i programmed the cypress chip07:36
pk__and on dmesg it was shown that a uvc device is connected07:36
pk__and /dev/video1 was created automatically07:37
pk__then i did  vlc -vvv --color v4l2://dev/video107:37
pk__says device opened successfully but no video07:38
pk__mithro: ^07:38
mithrowhich test pattern?07:39
pk__yellow rectangles07:39
pk__with shades of manu colours :)07:40
pk__mithro: what command you use to play the device finally?08:07
mithrocan you send a picture?08:07
pk__my screen?08:07
mithrothe test pattern08:14
pk__yes got the video this time08:24
pk__but the frame rate is too low08:25
mithropk__: the captured frame rate on 720p will be roughly 17fps at the moment, we haven't had time to optimise the mjpeg core for full frame rate08:31
mithro(the hardware can do 30fps easily)08:31
pk__it is sending raw or mjpeg ?08:36
pk__ohh so v4l2 automatically decompresses mjpeg and the player always gets raw video08:37
pk__is that true?08:37

mithropk__: you have two options09:33
mithroraw or mjpeg09:33
mithropk__: appreciate feedback on the documentation10:09
thaytanpk__, libv4l will automatically do decompression if vlc is using that10:42
mithrothaytan: ping?11:29
mithrothaytan: now I totally forget what I was going to ask you :P11:29
*** dhanush has joined #timvideos11:30
thaytanthat's why you should never ask to ask ;)11:30
mithrothaytan: well the primary thing I was going to ask you11:30
mithrothaytan: secondary things11:30
mithrothaytan: * I assume you are too busy to mentor a gstreamer related GSoC project?11:30
thaytanprobably, I've never done it to assess how much effort it takes11:31

thaytanartifactory cut them and posted them over?11:33
thaytanah robodino11:33
mithrostill working on trying to get one at work11:34
mithrothaytan: I had something I wanted to ask regarding the gst-plugins-dvswitch, but can't remeber what11:34
mithromentoring totally depends on the student. I estimate around 10 hours a week, but CarlFK thinks that is too high11:36
mithrothaytan: have you heard of snowmix btw?11:38
thaytanrings a bell11:39
mithroCarlFK: https://sourceforge.net/p/snowmix/wiki/Development%20Plans/11:39
thaytanyeah, I don't have 10 hours a week11:39
tpb<http://ln-s.net/Asp0> (at sourceforge.net)11:39
mithrothaytan: yeah I didn't think so11:39
dhanushmithro: I am interested to work on porting flumotion to gstreamer 1.0 as part of a GSoC.11:42
dhanushHow do I get started on it?11:42
*** dhanush has quit IRC12:48
pk__mentoring does not takes much time13:26
pk__and if this is first time you are getting 2-3 slots at max13:30
pk__so only 2-3 serious mentors and students will be needed13:33
pk__and ideas page look good13:35

parxFancy schmancy.  A magical gift from Santa?19:44
CarlFKif that's the best Santa can do, I am disappointed19:47
CarlFKit is pretty clunky.  but an image on a web page isn't normally used for doing data entry into a web page, so .. um.. I am not really sure what "good" should look like19:47
