aps-sidsmithro: I'm wondering why is watchdog not able to fix flumotion?07:48
mithroaps-sids: that is a good question07:48
mithroaps-sids: which I don't understand07:48
*** Niharika has quit IRC07:54
mithroaps-sids: if you can figure that out, I'd be really happy! :P07:56
aps-sidsmithro: yeah, I'm looking at that only.07:56
aps-sidsI love making out lives easier :D07:56
aps-sidsmithro: I'm not able to kill watchdog on hays collector. Can you take a look?08:24
mithroaps-sids: what trouble where you having?08:25
mithroaps-sids: I think you meant barbie right?08:25
mithroaps-sids: sometimes you need kill -908:25
aps-sidsmithro: It was stuck at "can't stop reactor" thing08:26
aps-sidsoh -908:26
aps-sidsmithro: what process is this command supposed to kill (after restarting flumotion service)?
tpbTitle: streaming-system/tools/watchdog/ at master · timvideos/streaming-system · GitHub (at
mithroaps-sids: itself08:36
aps-sidsmithro: you mean the watchdog? Apparently it says "no such process"08:37
mithroaps-sids: it's a safety measure08:37
mithroaps-sids: the watchdog should exit cleanly08:37
mithroaps-sids: but if it doesn't it should be killed08:37
aps-sidsmithro: and is there a difference in running "/etc/init.d/flumotion stop" and "service flumotion stop" ?08:38
mithroaps-sids: that has always confused me08:39
aps-sidsmithro: I think we should replace "/etc/init.d/flumotion stop" with "service flumotion stop"

tvCommitBotstreaming-system/master 6f64662 Amanpreet Singh: Use service instead of /etc/init.d/ in watchdog...08:51
*** tvCommitBot has left #timvideos08:51
aps-sidsmithro: done, now we need to setup again?08:52
mithroaps-sids: no, you just need to do a git pull08:52
aps-sidsat collector box right?08:52
mithroaps-sids: well, the encoders too08:53
aps-sidsmithro: okay, and separately for every room in collector?08:54
mithroaps-sids: you mean each collector, the reason you only ssh into one box is because we are remote to the venue08:55
aps-sidsoh, yes08:55
aps-sidsmithro: Is it a good idea to keep this (while true; do python -m user:[email protected]; sleep 30; done)  inside watchdog script and maybe pass arguments for sleeptime?09:01
mithroaps-sids: btw you just pasted a username/password into a logged IRC channel....09:02
aps-sidsoops, really sorry09:02
mithroaps-sids: we could have a watchdog wrapper wrapper09:02
mithroaps-sids: luckily we can just change it in the config.private.json and then run the pusher09:03
aps-sidsmithro: I've git pulled and restarted watchdog on all 4 collectors and encoders09:09
mithroaps-sids: btw, how did things go last night?10:01
aps-sidsmithro: one collector went down, watchdog couldn't handle. had to manually restart flumotion10:02
mithroaps-sids: yeah10:13
mithroaps-sids: it would be nice if the watchdog / register commands where a single entity10:13
mithroaps-sids: and where a web-server rather then a command line tool10:13
mithroaps-sids: I started doing something like that at
tpbTitle: Starting to merge the watchdog and register into a fluhelper module. · 8f18abf · timvideos/streaming-system · GitHub (at
mithroaps-sids: but never got all that far10:15
mithroaps-sids: it would also be nice if the watchdog understood the flumotion pipeline10:15
mithroaps-sids: IE, there is no point restarting all but the front element which is hungry10:15
aps-sidsmithro: I thought watchdog tries to restart just that element and a full restart if that fails.10:16
mithroaps-sids: it restarts any individual component that is in non-happy state10:17
aps-sidsmithro: so it should restart non-happy and non-hungry component?10:18
mithroaps-sids: and once it's doing enough restarting, it gives up and does a restart10:18
mithroaps-sids: nah, sometimes a component is hungry that is the problem10:19
mithroaps-sids: but if you have something like     producer -> demux -> encode -> mux -> etc10:19
mithroproducer (hungry) -> demux (hungry) -> encode (hungry) -> mux (hungry) -> etc10:19
mithrothen it should just restart the producer10:20
mithrothen if you get something like this10:20
mithroproducer (happy) -> demux (happy) -> encode (hungry) -> mux (hungry) -> etc10:20
mithroit should restart the encoder10:21
aps-sidsmithro: while porting generic decoder here,  using "Gst.Pad.new_from_template()" leads to a crash.10:45
aps-sidsits similar to this bug,
tpbTitle: Porting generic decoder · cf3cfbf · aps-sids/flumotion-orig · GitHub (at
tpbTitle: Bug 702062 crash after Gst.Pad.new_from_template (at
aps-sidsmithro: if you look at comment 4,5  I think python-gi version might be a problem since I have 3.2.2 on precise10:46
mithroaps-sids: so, how far are we from be able to run a encoder/collector using the timvideos config?10:50
aps-sidsmithro: this decoder, if fixed, will fix many other problems with other components. I've ported most of them, but can't test because of this decoder not working.10:51
mithroaps-sids: I don't quite understand how this decoder is connected? Is it the base class or?10:54
aps-sidsmithro: its required for decoding the stream from fgdp producer
tpbTitle: streaming-system/tools/flumotion-config/pusher/encoder.xml at master · timvideos/streaming-system · GitHub (at
mithroaps-sids: technically that block could be replaced with a more specific component10:57
mithroaps-sids: well, we know what type of video we are sending it, because we control the collector11:17
mithroaps-sids: is that the last step?11:34

aps-sidsmithro: yeah almost last step, and some more testing and small fixes.12:17
mithroaps-sids: well, once I get this pin issue figured out, lets see if we can figure out what is needed for twisted upgrade12:19

tpbTitle: desmaj / orbited / commit / 0748fc94eb08 Bitbucket (at
mithroaps-sids: good question14:13
mithroaps-sids: you were saying you can run flumotion without installing?14:19
mithroaps-sids: you were saying you can run flumotion without installing?14:19
aps-sids mithro yes, that's what I do14:19
mithroaps-sids: can you explain how?14:20
aps-sidswe need to activate the local environment14:20
aps-sidsusing ./env bash14:20
aps-sidsexecutables are made in bin folder14:20
*** CarlFK has quit IRC14:21
mithroaps-sids: so it seems I have to first?14:22
aps-sids./env bash14:23
aps-sidswhich flumotion14:23
mithro0.14 should be new enough to cause the issue right?14:27
mithrotwisted 0.14?14:28
aps-sidsIs it 0.14? Let me check14:28
mithroaps-sids: how do I start flumotion now? I normally use the "service flumotion start" :P14:30
aps-sidsmithro: it's the right time to use flumotion-admin ;)14:30
mithroaps-sids: flumotion-admin will start flumotion?14:31
aps-sidsmithro: it will start a gui and u can start a manager, worker and add components. or are you trying to run streamin-system config?14:32
mithroaps-sids: no14:33
mithrojust something basic14:33
aps-sidsthen start admin, choose 3rd option14:34
aps-sidsand follow the wizard choosing default options14:35
mithroaps-sids: I'm trying to run flumotion inside virtualenv14:35
mithroaps-sids: seems to kind of work14:35
mithroThe command that failed was:14:36

mithroI think that means it14:36
mithroI think that means it's failing14:36
mithroaps-sids: where do the logs end up?14:37
aps-sidswait wait, I start admin with cmd  "flumotion-admin"14:37
mithroaps-sids: that was the output from flumotion-admin14:38
aps-sidsmithro: if it fails due to twisted issues, output is like this --

mithroCarlFK: ping?15:18
mithroaps-sids: the stupid package hooks flumotion has are fighting with an absolute import that twisted is trying to use15:23
mithroaps-sids: the package hooks should all be ripped out eventually15:23

CarlFKhmm.. not sure I am getting dhcp now15:52
CarlFKnot sure how this connection is up15:53
aps-sidsmithro: I initially started from original flumotion repo (not the timvideos one) and recently merged timvideos master branch with my repo15:53

*** CarlFK has quit IRC15:56
aps-sidsmithro: you have any idea where the flumotion core dump is stored?16:13
mithronot really16:13
mithroaps-sids: you get a core dump now?16:22
aps-sidsmithro: getting that when using "Gst.Pad.new_from_template()"16:23
mithroaps-sids: you should see if flumotion runs on trusty now16:24
aps-sidsmithro: the twisted-fix branch?16:24
mithroaps-sids: that would give you the new gi16:25
mithroand trusty has gstreamer1.0 in the repo16:25
mithroaps-sids: starting on ubuntu precise was always just a temporary measure16:30
