aps-sidsmithro: still no luck with the LinkError. Basically, while trying to link srcpad to sinkpad, I get a "GStreamer-CRITICAL **: gst_mini_object_ref: assertion `mini_object != NULL' failed" and consequently a "<enum GST_PAD_LINK_NOFORMAT of type GstPadLinkReturn>"08:34
aps-sidsHere's the part of code where error occurs - https://github.com/aps-sids/flumotion-orig/blob/porting-to-gst1.0/flumotion/component/feedcomponent010.py#L918-L93408:34
aps-sids#gstreamer people tell that "It might be a refcounting bug"08:34

aps-sidsmithro:  I don't understand why the pads are not compatible since we get them using get_peer() and unlink them in the first place. I think problem is in Blocking probes which are used in place of "set_blocked_async"08:34

mithroayush3504: got your power back?09:45
mithroaps-sids: will look at in a moment09:45
aps-sidsmithro: okay. I got an idea and I'm trying that.09:45
aps-sidsyay \m/ Problem fixed. phew...09:58
aps-sidscleaning, committing and posting update..09:58
mithroaps-sids: great!10:06
mithroaps-sids: I won't look at it then :P10:06
aps-sidsyeah, don't need to. I'll post the problem and solution.10:06
aps-sidsSo, now I have a perfectly working Test Audio + Video stream that I can stream and watch :)10:07
mithroaps-sids: awesome!10:29

mithromparuszewski: ping?11:45
mparuszewskimithro: pong11:45
mithrogot some time to chat?11:46
mparuszewskiI will be more available at 1pm utc. :) Would you like to talk on hangouts or here?11:48
mithrohere would be preferred, I'll be in bed by then11:52
mparuszewskiI have 5-10 minutes now, we can talk now. :)11:54
mithromparuszewski: want to chat about, a) where the planet is at, b) where the new website is at, deployment and editing, c) the GitHub issues tool11:54
mithromparuszewski: will probably take longer than 5-10 minutes11:54
mithroI can't do tomorrow or Thursday either. Maybe I can catch you on the other side of sleeping in like ~10 hours?11:55
mithroayush3504: ping?11:55
mparuszewskiOk, I understand. :) 10 pm utc will be great. :)11:57
mithromparuszewski: okay11:57
aps-sidsmithro: I just posted on my blog.12:01
mithroaps-sids: okay, we should make sure we get someone to replicate your result12:03
aps-sidsmithro: Yes. Also, this was my milestone for mid-term evaluation. You should probably give me some instructions about writing documentation and other tasks while I continue working with other components.12:03
ayush3504mithro: back12:25
mithroI'm heading to bed anything you need before I go?12:30
ayush3504mithro: can you point me to the open source cypress firmware you had mentioned?12:33
tpbTitle: FX2 CyStream throughput test with SDCC and fx2lib | All My Brain (at allmybrain.com)12:34
ayush3504mithro: thanks12:34
mithroThere are multiple ones out there. Do a search for fx2 firmware / code / examples12:35
mithroThere was some stuff in a github issue to (the one about porting to sdcc).12:35
mithroGoogle is your friend :)12:36
mithroHeading to it now.12:36
ayush3504mithro: okay! thanks :)12:36
ayush3504mithro: good night. I hope I will be able to catch you around morning?12:36
mithroI'll be back in like 8-10 hours12:37

CARAM_mithro: any tips on testing encoder/collector configs?22:18
mithroJust getting up now, I'll be around in about 30 minutes22:24
CARAM_I'm having trouble getting an encoder setup, CarlFK's notes mention using an already existing one22:44
aps-sidsCARAM_: what are you trying to do? I might help.22:49
CARAM_just need any encoder up and running, any of the ones in flumotion config will work?22:51
aps-sidsCARAM_: encoder will need a feed as well. Here's a sample working config you could use. - https://github.com/aps-sids/flumotion-orig/blob/8223a46cacf0beb8889dcfe704343ed20ca5be7f/test_config.xml22:52

aps-sidsthere are two encoders being used in this22:53

mithroI'm here now23:11
mithromparuszewski: you still awake?23:11
mithroayush3504: ping?23:13
ayush3504mithro: pong23:24
mithroayush3504: one thing I forgot to mention last night is that we could just break the headers into individual pins23:26
mithroayush3504: how are things going? What progress have you made? Do you need any more help?23:26
ayush3504mithro: hmm, like spread it throughout the daughter board to give it more stability?23:26
ayush3504mithro: not much, i got to sleep evening and woke up early (an hour ago)23:27
ayush3504mithro: we need to discuss things that are important to schematic - like we need to discuss your idea of stacking the daughterboard artwork on the motherboard pcb and the bidirectionality of midi and dmx.23:28
mithroNo, I mean break the 2.54 pin headers into individual pins so they fit the rs232 layout.23:31
mithroayush3504: did you get the mechanical information for existing expansion boards into the spreadsheet?23:32
ayush3504mithro: not yet, but how will that help? coz the we're limited mainly by your case dimensions right?23:32
mithroThe case dimensions are flexible and informed by the above.23:33
ayush3504mithro: but, existing expansion boards seem to be just the right size for their application.. i..e they seem to be arbitrary. what kind of things do you think are important to note from those?23:35
ayush3504mithro: for e.g. i have the vmod bb board and it's sized just enough to have the connector, header and its breadboard. I don't see it having a standard size23:36
mithroayush3504: yes, but if we make the case large enough to fit all existing boards then that is useful23:40
mithroayush3504: these things are all iterative, we collect information and then use that information to decide how to proceed23:41
mithroayush3504: once we have the information we can make better decisions instead of guessing23:41
mithroonce you have the information you can decide to ignore it23:43
ayush3504mithro: okay. Since I do not have all the boards, and I don't think there's official information on this. Should I be asking the HDMI2USB group to measure the dimensions of their expansion boards (that I don't have) with a scale?23:45
mithroayush3504: The information is probably on the Digilent website23:45
ayush3504mithro: I couldn't find. I see documentation and schematics.23:46
mithroayush3504: looks like you are right, you do have the picture and know the size of the VHDCI header though23:47
mithroayush3504: you can also try emailing digilent23:48
ayush3504mithro: haven't looked at it yet, but i think they have the connector dimension on the website.23:48
ayush3504mithro: yes, i'll do that23:48
mithroayush3504: did you purchase any expansion boards?23:48
ayush3504mithro: yes, vmod bb23:49
mithroayush3504: it seems safe to assume that they used the same VHDCI connector for all the boards, so you can measure that and use it for reference on the pictures23:50
ayush3504mithro: sure23:51
mithroayush3504: and your best bet is to actually download the image, draw lines on it using something like gimp and then using the measure tool23:51
mithroayush3504: then actually saving / posting the images somewhere23:52
mithromparuszewski: I assume you've gone to bed?23:52
ayush3504mithro: ha, okay. I'll put a warning with that spreadsheet :p23:53
mithroyeah that is perfectly fine23:53
mithroayush3504: try your best and then other people can improve it23:53
ayush3504mithro: sure, any ideas about the bidirectional thing with MIDI and DMX and the IR remote that you want this to work with?23:54
mithroayush3504: I was pondering it23:55
mithroayush3504: give me 5 minutes23:55
ayush3504mithro: sure, no prob23:55
