CarlFKmithro: welcome back!01:42
mithrojust starting to go through my email, have 60+ messages to look at01:42
mithroCarlFK / shenki / xfxf: we still of the GSoC people the blog post from LCA/TimVideos Sprints01:43
mithroCarlFK / shenki / xfxf: we still owe the GSoC people the blog post from LCA/TimVideos Sprints01:43
shenkimithro: woot!01:43
mithroshenki: I see lots of mini-spartan-6+ activity01:44
shenkimithro: oh? where?01:44
shenkimithro: ive been flat out with work since getting back from lca01:44
mithroshenki: I'm subscribed to the forums01:46
shenkiah cool01:46
shenkii out a design onto mine01:46
shenkibut i wasn't near a HDMI device to test tit01:46
shenkis/tit/it01:46
mithroshenki: so I think we should have a "Port the HDMI2USB firmware to miniSpartan6+" as a GSoC project01:48
mithroshenki: plus "Design a HDMI2Novena expansion board" as well01:48
shenkimithro: yep!01:49
mithrowe have until "Org Application Starts: February 09 at 19:00 UTC" or 3 days, 17 hours remaining to get things ready for GSoC01:49
shenkiokay. what needs to be done?01:49
mithroshenki: fixed up all our issue trackers01:51
mithrowhich means making sure everything is tagged correctly01:52
mithroshenki: make sure all our "new" ideas are in issue trackers01:52
mithroshenki: lots of work on making the website more friendly01:52
mithroshenki: and making "setup" really quick and simple01:52
mithrothis year I think we are going to concentrate on gst-switch and HDMI2USB as our two big projects01:52
mithrowith the HDMI2USB, the main thing I'd like to concentrate on this year are01:53
mithro a) reliability & debugging01:53
mithro b) code quality01:53
mithrowith the idea by the end of the year we can start looking at extending support for more than one board01:54
shenkisounds good01:54
shenkimithro: have you got any displayport to mini-dp cables?01:54
mithroshenki: yes01:55
shenkiokay01:55
mithrodo yo want me to send one back with my parents?01:55
shenkiwe should see if we can reproduce the bad behaviour with that01:55
shenkii can buy one if you point me to where you got them01:55
mithroamazon01:58
mithroshenki: they didn't ship to Australia01:59
shenkiah01:59

apsmithro: Morning. Take a look and suggest how should I go about replacing pngcrush - https://github.com/timvideos/streaming-system/pull/79#issuecomment-7232076502:51
tpbTitle: Add script to check and show no-signal preview by aps-sids · Pull Request #79 · timvideos/streaming-system · GitHub (at github.com)02:51
mithroaps: just call pngcrush on the output file before moving it to a final destination03:08
mithroaps: otherwise looks good03:10
apsmithro: okay. Also, is it a good idea to use gstreamer for taking snapshot than calling mplayer thing generate.sh was using?03:10
mithroaps: I would have started just using mplayer, but if the gstreamer stuff works - then I don't see any reason not to use it03:11
mithroaps: only thing is you probably want to make this threaded03:11
apsmithro: It works fine on my local machine03:11
mithrobecause if for example there is a firewall issue, the gstreamer command might take 30-60 seconds to timeout03:12

lukas2511i can also make a nice little pullrequest for you if you want, add some cat pictures or whatever, no problem ;)03:15
CarlFKmithro: re: No Signal generator - why would there be anything like firewall issues?  (all the boxes / connection are running on machines we control, right?)03:18
mithroCarlFK: because there have been firewall issues in the past03:18
mithroCarlFK: and sometimes it takes a while to fix03:19
mithroCarlFK: and you don't want all the preview images blocked because one is failing03:19
mithroaps: should be like 2-3 lines to add threading support03:19
mithrofrom threading import Thread03:19
mithroclass Preview(threading.Thread):03:19
mithro  def run(self):03:20
mithro    while True:03:20
mithro      <generate preview>03:20
CarlFKPersonally, I would rather have simpler code than try to contend with problems that should be fixed anyway03:20
CarlFKer, make that problems that shouldn't be happening in the first place03:21
mithroCarlFK: the code is simpler by 5 lines03:21
mithroIt means we can delete the following shell script -> https://github.com/timvideos/streaming-system/blob/check-signal/tools/preview/generate.sh03:23
tpbTitle: streaming-system/generate.sh at check-signal · timvideos/streaming-system · GitHub (at github.com)03:23
mithroaps: do you scale down the video size? or is that already part of the gstreamer pipeline?03:24
CarlFKshouldn't the gstreamer pipeline just keep running and generating an image every X seconds, and then use noimpae.png when that exits?03:24
CarlFKmithro: the scaling is done in the pipeline03:24
apsmithro: scaling done in pipeline - https://github.com/timvideos/streaming-system/pull/79/files#diff-e4fd8ffb95125dfe686c67164d487690R1803:24
tpbTitle: Add script to check and show no-signal preview by aps-sids · Pull Request #79 · timvideos/streaming-system · GitHub (at github.com)03:24
mithroaps: great!03:25
mithroaps: a lot of the problems that the shell script was having is worked around by your head request on line 4303:27

LeeSSorry it took so long.03:29
mithroLeeS: could you do a rebase onto master03:37
shenkimithro: are those adapters passive?03:44
shenkimithro: oh, they are miniDP to HDMI03:44
shenkimithro: i wanted miniDP to DP03:44
mithroshenki: why miniDP to DP?03:51
shenkimithro: so that we are talking directly to the device, instead of via the translator chip in the cable03:51
apsmithro: I just noticed a problem. How do I import config.py (non-package) which lies in a parent directory?04:20
apsokay, I can use absolute import04:21
mithroaps: see what the other tools do04:21
CarlFKhow I do it: sys.path.insert(0, '..' )04:51
CarlFKah, "other tools" is code in the streaming server project?04:52
MaZderMindmithro: welcome back04:53
MaZderMindmithro: I'm really busy with paid work this week but I started into rewriting the timing management of the int.-tests04:55

MaZderMindmithro: would you mind taking a look at https://github.com/MaZderMind/gst-switch/blob/int-tests-rewrite2/python-api/tests/integrationtests2/test_controller.py and especially at https://github.com/MaZderMind/gst-switch/commit/c9cfee60f4c2c8935e2ff8955c0fb83a7f94bbe518:40
tpbTitle: gst-switch/test_controller.py at int-tests-rewrite2 · MaZderMind/gst-switch · GitHub (at github.com)18:40
MaZderMindthe latter removes the sleep(0.5) with a more powerful output monitoring facility. I'm pretty sure these sleeps are one of the main reasons the int-tests failed on travis ans also they make the tests much slower then required when running on localhost18:41
MaZderMindthis way we can ie. wait until the server itsself tells that the preview-port should be ready and then probe it via tcp18:42
