xfxfmithro: i still have major doubts about the routing/nat ability of that device00:59
mithroxfxf, probably00:59
xfxfannoyingly i have a 4g usb card at home that 'just works' on ubuntu00:59
xfxflet me see if i can buy one outright...00:59
mithroxfxf, I think I might get a multipath project developed01:08
mithroso we can have both Optus and NextG up at the same time01:08
mithroand it'll send the data over both01:08
mithrowe also need some much better monitorin01:08
xfxfhow would you do that; aggregate the data back at the relay point?01:09
xfxfi am 75% certain that this would work fine with a proper USB 4g card01:10
xfxfwell, assuming no network congestion issues01:10
xfxfwhat we're seeing is that router thing being a pile of balls01:10
xfxfgoogling the model number results in lots of peopel complaining about dropouts01:11
xfxfwhen i was fiddling with it yesterday i was able to load a usbserial module by forcing the vendor/product id  and talk to the modem directly01:11
xfxfproblem was the computer locked up after a minute or two, but it mayy be a kernel bug01:12

xfxfmithro: ^^01:17
mithroTasman A needs help with lights01:21
mithroxfxf, ^^01:22
xfxfta, will be over01:23
xfxfif you're with them, tell them they can sms me, as their sheet says :)01:24
mithroxfxf, there is only 1 guy here?01:26
xfxfyes, that's intended01:45
xfxfsame as prior years01:46
xfxfstrong preference for 2-3 per room as per pycon us, but we're doing this on less than 4% of the budget01:47
xfxf1 works, just means that person needs to pay full attention01:47
xfxfalso re lighting01:47
xfxfhave organised spot lihtts to go in at lunch with venue av01:47
*** mithro has quit IRC01:48
xfxfinternets here is awesome01:48
xfxfCarlFK: you watching the stream?02:00
xfxfhow is it working?02:00
CarlFK query = query % tuple(( get_codec(a, self.encoders)(db, a) for a in args )   Is this bad? :)02:00
CarlFKpretty good02:00
xfxfwe're streaming it over a crappy mobile hotspot over mobile data02:01
CarlFKdrops now and then.. like every 20-20 min02:01
xfxfnice it works, gives us good options for streaming02:01
xfxfplonk standard dvswitch loop in, join slave camera to a wireless network, stream02:01
xfxfthat's the 4g device02:01
xfxfnot the network02:01
xfxfwith a better device this would work better02:02
xfxfi think tim worked out the data to be about 1gb/hr, but that's at 2mbits02:02
xfxfat 1mbit (current bw?) it'd be about half02:02
CarlFKit is about the same as any other stream... so pretty much on par with what people expect02:02
xfxf12gb is $18002:02
xfxfwhich.. for streaming.. is doable02:02
xfxfso beyond s3 costs for the relay, we're talking like $80/day/room or something02:03
xfxfas horrible as 12gb for $180 is, the venue we're in can't give us any better than an ADSL connection, and it's a lot cheaper than what venues charge anyway :)02:04
xfxfhow much was that connection for pycon us - some stupid figure?02:04
CarlFKmeh, it was a funny number that's really just part of being at a venue02:05
xfxfother advantage of mobile data is we don't ahve to run a network between rooms, which can be challenging/impossible in some venues02:05
xfxfoh, i realise02:05
xfxfbut it's still a real cost to a conference if they want streaming02:05
xfxfirrespective of hw the figure is derived02:05
CarlFKand we don't have to deal with venue tech dummies02:06
xfxfhow many telcos have LTE in the US?02:07
xfxf4G for most is what we call 3G02:07
CarlFKwhat's lte02:07
CarlFKare you in the Jacob room?02:07
xfxfin the same room that is streaming02:08
xfxfso yes02:08
CarlFKcan you get them to do pnp for a sec?02:08
CarlFKI want to see if audio drops02:08
xfxfone sec02:08
xfxfaudio ok?02:08
CarlFKi think02:09
CarlFKbring the mic level back up02:09
xfxfaudio being done by venue, can't02:09
xfxfwell, easily02:09
xfxfthere was an audio bug with pnp?02:09
CarlFKso dvswitch without any effects just moves DV frames around .. 120000 bytes each.02:10
CarlFKwhatever frame comes in, goes out, not modified02:10
CarlFKpnp and fade have to decode, construct a new frame, encode back to DV02:10
CarlFKsomething about the encode parameter does not get along with gstreamer's dv decode02:11
CarlFKbut ffmpeg (so ffmpeg2theora and melt) is not effected by it02:11
CarlFKoh, and it was in both my PPA version of dvswitch, and git master.  Ben did a "I think I see the problem, try this patch" which I think I applied and it didn't fix it02:21
xfxfah, right02:31
xfxfmakes sense - was going to say, how the hell would there be an audio drop that isn't in the saved file02:31
xfxfbut, makes sense if there are incompatibilities between the dv encode/decode02:31
xfxfis this a bug in dvswitch?02:32
CarlFKI think the bad data does end up in the saved file..but it isn02:33
CarlFKbut ffmpeg workes around it, gstreamer doesn't02:34
CarlFKthe audio data is there, just something funky with the metadata flags something02:34
*** mithro has joined #pycon-av02:43
CarlFKmithro: dvswitch pnp didn't kill the audio.  not sure what dv libs ryan's dvswtich uses - any chance your collector gstreamer side is different?02:48
mithrowe not using dvswitch pnp02:50
mithrothere is a hardware mixer involved02:50
mithrodvswitch just gets the already mixed feed02:50
CarlFKxfxf: video!03:00
CarlFKmithro: hit xfxf!03:00
CarlFKther we go\03:00
mithroCarlFK, you watching the stream?03:11
xfxfCarlFK: remember martin? he's the one manning the stream you're watching03:14
xfxfi'm running around between rooms with my hair on fire as per usual03:14
* CarlFK knocks on the screen HI MARTIN!!!03:14
xfxfCarlFK: the dvswitch we're running should be the same as what your pycon usa 2013 laptops used03:14
xfxfi'm using the same image03:14
xfxfwhich is an old version of ubuntu with your deb files afaik03:14
CarlFKbut what did you use to make the pnp?03:14
xfxfwe're using a hardware video switcher but it's only for switching between two lecturns03:15
xfxfand only one twinpact, grabbing the output of that03:15
CarlFKwill you two figure out what is going on :)03:15
xfxfi don't understand your question03:15
CarlFK(09:50:16 PM) mithro: we not using dvswitch pnp03:16
xfxfwe are03:16
xfxfmithro: what are you referring to?03:16
xfxfthis is basically the same as the loop at pycon usa for the main room, but cut down03:16
xfxfCarlFK: stream still working ok?03:17
CarlFKoh hell.. we jinxed it03:17
CarlFKnm, just presenter pausing03:17
xfxfshould i get a long stick to poke him with?03:18
CarlFKyeah, this talk is boring03:19

skayI like testing03:27
xfxfthat said, if you're looking at this carl, and you reckon it's working well, then the experiment is working from my perspective (i care about dvswitch -> relay, i.e. is 4g workable for doing this)03:27
xfxfskay: hi!03:28
Guest24680I care the switching and video is pretty03:28
Guest24680quality matters.03:28

CarlFKcaptainvideo:  I can hear him typing ... i bet it looks interesting04:28
xfxfhow long was audio out for04:29
xfxfalso this is the exact argument _for_ streaming04:29
CarlFK30 seconds04:29
xfxfright, ta04:29
captainvideoNOTE TO SELF. dvswitch is alive.04:31
xfxfCarlFK: wtf happened to the patch for dvswitch that allowed for audio monitoring?04:31
CarlFKno clue04:31
CarlFKI use dvswitch-command -- ffmpeg stuff04:32
xfxfi'm not a fan of tha tthough04:32
xfxfvisual indicator is ok04:32
xfxfactual audio out is delayed and cpu heavy04:32
xfxfany idea where that patch went?04:32
xfxfi have somebody who can review it04:32
CarlFKnever saw the patch04:32
xfxfwho wrote it?04:33
xfxfor was it the lca2011 dude who ended up dissapearing?04:33
CarlFKI seem to remember it being related to lca..04:34
xfxfguessing it never actually fully existed04:35
xfxfguessing intent to create which was miscommunicated04:35
CarlFKor it kinda worked.. on his box.. using who knows what... and crashed...04:35
xfxfwhat are basic features we really need to get into dvswitch, keeping in mind i'm keen on phasing it out within 12 months04:35
xfxf- not disabling fade on pip04:36
xfxf- audio out ability04:36
xfxfanything else?04:36
CarlFKi don't even think those are worth messing with04:36
xfxfso anything?04:36
xfxfyou can't, you just derped04:37
