| mithro | aps-sids: but that I think is unrelated | 04:00 |
| mithro | aps-sids: the error seems to indicate that the eater / feeder elements where not correctly set up | 04:00 |

| tpb | Title: Rejected Emojis (at rejectedemojis.tumblr.com) | 04:27 |
| aps-sids | mithro: I don't think it should be "dvswtich name=src %s" since the name of element itself is dvswitchsrc and dvswitch will not be found by gstreamer | 04:32 |
| mithro | aps-sids: name=src allows you to use pipeline.get_by_name("src") to get that element - currently it doesn't have a name | 04:33 |
| mithro | aps-sids: take a look at some of the other producers | 04:33 |
| aps-sids | mithro: "dvswtich name=src %s" gives -- no element "dvswitch" | 04:35 |
| aps-sids | "dvswtichsrc name=src %s" gives same error as in blog | 04:35 |
| mithro | "dvswitchsrc name=src %s" | 04:35 |
| mithro | aps-sids: yeah, as I said that is probbaly unrelated | 04:35 |
| aps-sids | okay | 04:36 |
| mithro | aps-sids: so you want to look at class ParseLaunchComponent(FeedComponent): | 04:36 |
| mithro | in flumotion/component/feedcomponent.py | 04:36 |
| mithro | aps-sids: that is what creates the elements that it is trying to get the name for | 04:37 |
| mithro | aps-sids: btw what is the actual name it is failing to get? | 04:37 |
| mithro | IE what is feeder.elementName ? | 04:37 |
| aps-sids | mithro: 'feeder:dv' | 04:38 |
| mithro | okay, that is a bit weird... | 04:38 |
| aps-sids | mithro: can you tell me where is self.feeders.values() coming from? | 04:39 |
| aps-sids | [<Feeder dv (0 client(s))>, <Feeder audio (0 client(s))>, <Feeder video (0 client(s))>] | 04:39 |
| mithro | oh I see now | 04:40 |
| aps-sids | mithro: pipeline.get_by_name works for audio and video | 04:40 |
| mithro | Take a look at | 04:40 |
| mithro | https://github.com/aps-sids/flumotion-orig/blob/9fa3fdb39b8b7ef79d0571f91d719337e362c281/flumotion/component/producers/dvswitch/dvswitch.xml | 04:40 |

| aps-sids | mithro: Okay, so that's where it comes from. But why pipeline.get_by_name() can't find it? I does for unported flumotion right? | 04:42 |
| mithro | ithe pipeline template at L100 needs a "@feeder:dv@" in there somewhere | 04:42 |
| mithro | see how there is a @feeder:audio@ | 04:42 |

| mithro | aps-sids: I have no idea :P | 04:44 |
| aps-sids | Fair enough. | 04:44 |
| mithro | aps-sids: maybe we have always had that error and I just never paid any attention to it? | 04:45 |
| mithro | aps-sids: maybe there is a fix in another branch? | 04:46 |
| mithro | aps-sids: take a look at flumotion/component/producers/firewire/firewire.py | 04:46 |
| mithro | aps-sids: maybe you fixed something else that had always been broken which showed up this issue :P | 04:48 |
| aps-sids | haha, yeah | 04:48 |
| aps-sids | mithro: there is a ' t. ! queue ! @feeder:dv@' in firewire.py | 04:48 |
| mithro | aps-sids: yeah | 04:49 |
| mithro | dunno why/how I removed it, because dvswitchsrc is almost a direct copy from firewire.py | 04:49 |

| rohitksingh | mithro: Isn't there any chance that we can have this layout? https://docs.google.com/drawings/d/1Q8SRjYLjhRFQtuQP0uSEUU5B_FltX_Y2pVN5fQyM6CE/edit?usp=sharing | 11:06 |
| tpb | Title: VGA Capture Mechanical Specification - Google Zeichnungen (at docs.google.com) | 11:06 |
| rohitksingh | mithro: My reasons are that in your proposed layout all the important traces (Analog RGB, HSYNC and VSYNC) are going to be very long. The datasheet warns that we should emphasize to reduce these traces as they pick up noises. The digital ones are not that critical but theses ones are. Whereas in layout in above drawing, the traces are comparatively very shorter in length. | 11:10 |
| mithro | rohitksingh: pong | 11:14 |
| mithro | rohitksingh: the problem with that layout is the edge the connectors are on | 11:16 |
| mithro | rohitksingh: can you move the AD chip downwards? | 11:17 |

| mithro | 8:47 PM <mithro> rohitksingh: can you move the AD chip downwards? | 11:23 |
| rohitksingh | mithro: ? | 11:24 |
| rohitksingh | Moving the chip downwards will increase length of all digital lines. Maybe colors lines won't be affected much but DATACK, HSOUT, VSOUT and SOGOUT might be | 11:24 |
| mithro | rohitksingh: what type of length are we talking? | 11:24 |
| rohitksingh | trace lengths...extra increase in lengths by about 40-45mm | 11:25 |
| rohitksingh | or lower at aorund 30-35mm | 11:26 |
| rohitksingh | mithro: For digital lines datasheet says "Try to minimize the trace length that the digital outputs have to drive. Longer traces have higher capacitance and require more instantaneous current to drive, which creates more internal digital noise. Shorter traces reduce the possibility of reflections." | 11:28 |
| mithro | rohitksingh: yes correct | 11:28 |
| mithro | rohitksingh: everything is a trade off :) | 11:29 |
| *** tija has joined #timvideos | 11:29 | |
| mithro | tija: you should extend your current program to support both modes | 11:30 |
| tija | mithro: okay | 11:30 |
| rohitksingh | mithro: So what do you recommend. Should I move ahead with your layout with some trade-offs? or go with my layout? | 11:32 |
| mithro | rohitksingh: I think we should drop them into the pcb and have a look at it | 11:32 |
| rohitksingh | mithro: great. I will start routing with your layout. Lets see how it comes out! | 11:34 |

| rohitksingh | mithro: okay then! I'm moving ahead with its routing! :) | 12:09 |
| mithro | rohitksingh: don't forget to line up the connectors properly | 12:10 |
| rohitksingh | mithro: yeah. This was just a hurried placement. Will align them properly (Although exact alignment is very difficult with coordinates, newer KiCad development version has alignment, P&S Router as well as length-matching) | 12:12 |
