|---|---|---|
| aps-sids | planet.timvideos.us is still being redirected | 00:03 |
| aps-sids | morning mithro | 00:04 |
| mithro | mparuszewski: we also need that monitoring | 00:04 |
| mithro | aps-sids: you have a happy flumotion component? | 00:06 |
| aps-sids | mithro: yes, videotest producer (only that is ported yet) | 00:14 |
| aps-sids | I'm using flumotion-admin of a working flumotion installation to view this. | 00:15 |
| mithro | aps-sids: commented on your blog post. | 00:17 |
| mithro | mparuszewski: I think the way we have the GitHub pages means code.timvideos.us and planet.timvideos.us are fighting? | 00:18 |
| aps-sids | mithro: there is one problem with the tests (both on my machine and travis) that since some modules are ported and others are not, running all tests (using trial flumotion.test) freezes, probably due of import conflicts but individual tests run (and pass) just fine. | 00:27 |

| mithro | aps-sids: I think trial can take a list of things to run? | 00:34 |
| aps-sids | mithro: I can add names of only ported modules in .travis.yml so only those tests are run? | 00:35 |
| mithro | aps-sids: maybe just a "working-tests.txt" or similar file? so people can run it locally too? | 00:35 |

| CarlFK | aps-sids: are you able to play a test stream in a video player? (like vlc) | 01:02 |
| aps-sids | CarlFK: encoder and streamer are not ported yet, so that won't work. As I mentioned in my post, I'm going to do it in this week. | 01:03 |
| CarlFK | what about the original unported code? | 01:03 |
| aps-sids | test stream works for completely unported code, not partially ported. I will post an instructions post soon. | 01:05 |

| shenki | mithro: any tips on setting up a machine? | 02:39 |
| *** mparuszewski has quit IRC | 02:41 | |
| mithro | shenki: we should use 14.04 as the base version I think? | 03:01 |
| *** ayush3504 has joined #timvideos | 03:14 | |
| shenki | mithro: yep | 03:41 |
| shenki | mithro: is it more expensive to run an instance in sydney? | 03:41 |
| shenki | hrm, pv vs hardware | 03:41 |
| shenki | is there a 'hackers guide to aws'? | 03:46 |
| shenki | it would make sense to use the free tier to install the tools, and then run it on the bigger ones when we're doing a build | 03:47 |
| shenki | tija: hello | 03:48 |
| mithro | Yes but I don't know by your much. The latency improvements are probably worth it. | 03:58 |
| mithro | S/your/how/ | 03:58 |

| mithro | shenki: I assume Xilinix stuff doesn't have an option to try and parallelize stuff? | 04:54 |
| shenki | mithro: you can run the multi-threaded par algorithims, yeah | 04:56 |
| shenki | mithro: they're different altorithims, so different outcomes to the single threaded ones | 04:57 |
| shenki | afaik | 04:57 |
| shenki | we should make sure everyone is using them if we switch to them | 04:57 |
| shenki | tija: do you have experience using the -mt options | 04:57 |
| shenki | ? | 04:57 |

| mparuszewski | mithro: planet and getting started are fighting, because planet folder on timvideos.github.io can behave in 2 ways: 1. It can be a folder inside timvideos | 05:20 |
| mparuszewski | Timvideos.github.io repository | 05:20 |
| mparuszewski | But planet folder on timvideos.github.io can also be a website from gh-pages in project planet. | 05:21 |
| mparuszewski | Sorry that I answered so late, but I was in bed at the time you wrote the message. :) | 05:21 |
| mparuszewski | Today I will be fixing both repos, and find a monitoring tool that will suits our needs. Maybe Google Analytics can do that. Definitely we need something to ping if website is up and check if content is loading properly. | 05:23 |

| mithro | shenki: did you get anywhere with setting up that machine? | 07:00 |
| mithro | shenki: and we should set up a way to idle timeout the machines too | 07:00 |

| mithro | ayush3504: do you have your power back now? | 07:09 |

| mithro | just wondering where rohit is... | 07:09 |
| mithro | hold on a sec | 07:09 |
| mithro | ayush3504: do you have power back on, IE should we do a normal hang out? Or should I call your phone? | 07:10 |
| ayush3504 | mithro: normal. i've joined | 07:10 |
| mithro | okay | 07:10 |
| mithro | if we need to do phone, I need to use an alternative room | 07:10 |
| ayush3504 | ok | 07:11 |
| shenki | mithro: no, i'll do some more on it tonight | 07:29 |
| shenki | mithro: i was thinking of setting up jenkins or something on a !aws machine | 07:29 |
| shenki | mithro: and that could fire up the aws machine, build the system, suck out the logs and bitstream, and shut it back down | 07:30 |

| ayush3504 | rohitksingh: are you making a 2 layer PCB or 4 ? | 10:19 |
| rohitksingh | ayush3504: 2 layer! | 10:22 |
| ayush3504 | just a note..if you take a look at the info about power supply rails on page 10 of AD9984A datasheet, you will see that it requires you to have ground plane. In general chips with multiple supplies, esp mixed mode chips require you to have that | 10:25 |
| ayush3504 | but you can get away with that if you make sure that the supplies in your circuit are star connected. This star ground is usually at the negative terminal of the bypass capacitor.. | 10:26 |
| ayush3504 | this may help : http://www.analog.com/library/analogdialogue/archives/46-06/AD46-06_FIG_02.jpg | 10:28 |
| rohitksingh | yes, there would be a ground plane below and in vicinity of the AD9984A. I'll look into the star ground thing. Never knew about it. | 10:28 |
| rohitksingh | many thanks for the help! :) | 10:29 |
| ayush3504 | no prob! :) | 10:29 |
| rohitksingh | I think i'm beginning to understand this star ground. Will see more | 10:33 |
| ayush3504 | basically the idea behind a star connection is that the current flowing to ground from one circuit does not create voltage drop in other circuit. in simple words, the ground currents of different circuits get isolated from one another with star connection | 10:36 |
| ayush3504 | by ground current i mean the current going from the respective power supply of a circuit to the ground | 10:37 |
| ayush3504 | i got to learn this when I had trouble running some ADC that was too sensitive to noise. Even your chip looks quite sensitive to grounding issues | 10:39 |
| rohitksingh | yeah, it is quite sensitive to voltages as well has noise due to its very high bandwidth | 10:47 |
| ayush3504 | see if there are reference designs based on that chip, that should you out with noise problems. | 10:58 |
| rohitksingh | there is one based on AD9984, and I'm using AD9984A. Mostly similar. It is there in the 'docs' folder of the "HDMI2USB-vmodvga" repository | 11:05 |
| rohitksingh | although its not a complete design, just schematic... | 11:08 |
| ayush3504 | Yes, I guess you can stick to that schematic except for the digital input part that you will be customizing. For the regulator part that you mentioned, I would prefer sticking to the power supplies given there in the reference design. It's generally a benefit for the manufactuers to show that their chips needs less extra parts so I would assume that those parts are necessary at least in the first few prototypes of the board. | 11:15 |
| *** FeltonChris has quit IRC | 11:17 | |
| *** FeltonChris has joined #timvideos | 11:19 | |
| rohitksingh | yeah! great suggestions! Will not be changing the power supplies atleast until whole project is almost done | 11:25 |
| ayush3504 | thanks and btw. i found some PCB layout suggestions in pg 40 of the datasheet. | 11:27 |
| mithro | rohitksingh: http://www.elmac.co.uk/pdfs/Lord_of_the_board.pdf | 11:45 |

| shenki | so a xilinx ise isntall is 18GB on my machine | 14:47 |
| shenki | which is annoying, as there is no way you want to dynamicly install that on a vm to do a build | 14:48 |
| shenki | so i wrote a fuse filesystem that records all the files that get opened in the ISE install dir when building the firmware | 14:48 |
| shenki | and copied all those files out | 14:48 |
| shenki | du -sh | 14:48 |
| shenki | 206M | 14:49 |
| shenki | very hacky - i assume if eg. a different vhdl package is used then it will fail | 14:49 |
| shenki | but for 1% of the file size, it's a bit of a win | 14:50 |
| shenki | in the time that i managed to do all that, the ISE download to the ec2 VM is still only at 61% | 14:50 |
