| 11:25 | felix_ | we tried to test the axiom with the sdi module here, but the kick_manual script failed with this message: https://paste.fedoraproject.org/paste/jjx0eFerXBhD7XrH9HUNOA
|
| 11:26 | felix_ | also the fan on the zynq board sounded rather unhealthy
|
| 11:28 | felix_ | not sure if some other image got flashed to the camera; i remember it working at 34c3

| 17:00 | se6astian | good evening
|
| 17:00 | se6astian | meeting time
|
| 17:00 | se6astian | who is here to participate?
|
| 17:00 | davidak[m] | hello
|
| 17:02 | Tr3n4rT | joined the channel |
| 17:03 | se6astian | davidak[m]: please go ahead
|
| 17:04 | davidak[m] | i can report how the 34c3 went
|
| 17:04 | davidak[m] | i organized an apertus° assembly
|
| 17:05 | davidak[m] | it was a long time very chaotic on our table, but there was some people from apertus
|
| 17:05 | davidak[m] | and also a lot of people interested in the project
|
| 17:05 | davidak[m] | general very positive feedback on the idea to have an open hardware camera
|
| 17:06 | davidak[m] | also that we have a working prototype
|
| 17:07 | seku | joined the channel |
| 17:07 | davidak[m] | we successfully connected 2 Betas to the streaming setup of the c3voc via SDI
|
| 17:07 | se6astian | the demo setup not the live recording setup I assume right?
|
| 17:07 | davidak[m] | with minor issues that where known
|
| 17:08 | davidak[m] | i don't achieved everything, but in general it was a success for me
|
| 17:08 | davidak[m] | se6astian: yes
|
| 17:08 | davidak[m] | i suggest to attend again next year. the project totally fit's there
|
| 17:09 | davidak[m] | but i wish se6astian and Bertl_zZ also attend to answer more detailed questions
|
| 17:09 | davidak[m] | and discuss the hardware design
|
| 17:09 | se6astian | thanks!
|
| 17:09 | davidak[m] | i can again organize everything
|
| 17:09 | se6astian | I would love to attend
|
| 17:10 | se6astian | but the timing is challenging to say the least :)
|
| 17:10 | davidak[m] | maybe one year :)
|
| 17:11 | se6astian | I hope so
|
| 17:11 | se6astian | quick update from my side
|
| 17:11 | se6astian | 1. we had piotr from https://1bitsquared.com/ visiting last week
|
| 17:12 | se6astian | he will host a video log show on youtube that covers the entire process of building the AXIOM Beta hardware from scratch
|
| 17:12 | se6astian | over the course of 2018
|
| 17:13 | se6astian | 2. we had another visitor today at the office who we will collaborate with to build an AXIOM Recorder device that acts as a camera controller as well
|
| 17:13 | se6astian | focus is on a proof of concept software first
|
| 17:14 | se6astian | 3. we will move the assembly facilities to a new office next week: https://factoryhub.at/
|
| 17:14 | se6astian | that will halt production of boards for a bit
|
| 17:15 | se6astian | as we first have to pack and move all machines
|
| 17:15 | se6astian | and then again unpack and setup everything again there
|
| 17:15 | davidak[m] | looks cool
|
| 17:15 | davidak[m] | can you use machines there?
|
| 17:16 | davidak[m] | and collaborate with other open hardware projects?
|
| 17:17 | se6astian | collaborate definitely
|
| 17:18 | se6astian | how any collaboration with the on site manufacturing equipment is done exactly we will need to see once we are there
|
| 17:18 | se6astian | its not like you can just go into the assembly line and start building your boards
|
| 17:19 | se6astian | but its definitely an interesting possibility, even if we just have a chat with the people working on the assembly line occasionally
|
| 17:19 | se6astian | ah another point:
|
| 17:20 | se6astian | 4. phabricator has been installed in the newest version at http://lab2.apertus.org/
|
| 17:20 | se6astian | we migrated all content over once
|
| 17:20 | se6astian | currently its a test/playground to see if everything is working properly
|
| 17:20 | se6astian | if there are no bugs we will migrate the live site to the new version
|
| 17:20 | se6astian | so please feel free to test and play around with lab2
|
| 17:21 | se6astian | any content there will be overwritten anywa
|
| 17:21 | se6astian | y

| 17:22 | danieeeel | <-- hand raised
|
| 17:22 | davidak[m] | can you also report what Bertl_zZ was working on?
|
| 17:22 | danieeeel | changed nick to: danieel
|
| 17:23 | se6astian | I would have loved to get an update myself :)
|
| 17:24 | se6astian | danieel: please go ahead
|
| 17:24 | danieel | well, with commercial projects finished/halted, we are looking back to production of our own hardware, the most easy one to put together is a SDI I/O card, with mainline kernel drivers
|
| 17:25 | danieel | there is no such device yet, since vendors like BMD or deltacast use their own drivers/api's, not V4L2
|
| 17:26 | danieel | the initial hardware is 6 din connector, 2x6G out, 2x6G in, 2x 3G i/o, putting together a 4in/2out (our reverse) operation, based on Artix with 8 MGTs, pcie x4
|
| 17:26 | danieel | we have our own s/g dma core for pcie in that..
|
| 17:26 | se6astian | interesting!
|
| 17:27 | danieel | the BMD devices are limited to SMTPE video, while we have some experience with Deltacast, which can capture RAW data (we used that in our 4k camera, on 3G sdi)
|
| 17:27 | davidak[m] | very good
|
| 17:27 | danieel | so the option to support custom formats is definitely there
|
| 17:27 | davidak[m] | we also talked about that at 34c3
|
| 17:28 | danieel | BMD is starting with some raw support now.. whereas we did that 3 years ago :) but then got diverted

| 17:28 | davidak[m] | the VOC would also like to have such a product
|
| 17:28 | davidak[m] | and other people around
|
| 17:28 | davidak[m] | one important point is to have access to error count and statistics
|
| 17:29 | davidak[m] | BMD don't support that
|
| 17:29 | se6astian | danieel: so are you interested in electronics production of this or development collaboration?
|
| 17:29 | danieel | like crc errors and mis-numbering the lines?
|
| 17:29 | arpu_ | joined the channel |
| 17:30 | danieel | we can prototype by hand (even BGAs), so maybe on low-volume series (10s) where it does not make sense to employ a commerical fab
|
| 17:30 | danieel | with 50-100+ it is again fine
|
| 17:30 | davidak[m] | crc
|
| 17:31 | davidak[m] | i think that is no problem with open hardware to support
|
| 17:31 | danieel | se6astian: rather use case scenario, the current V4L2 does not support 10bit yuv video
|
| 17:32 | danieel | davidak[m]: the biggest problem are API's ... this is why other vendors choose to use their own (with benefit of being same across platforms)
|
| 17:33 | illwieckz | left the channel |
| 17:33 | davidak[m] | Ffelix_ said that our SDI module for the beta also has the essential parts for such a product and only need some work
|
| 17:33 | danieel | we did a CXP (CoaXPress frame grabber) where the non-video data was on ioctl, by device nodes according to card or a input connector
|
| 17:33 | se6astian | sounds interesting, I would suggest to chat with Bertl_zZ about the technical details
|
| 17:34 | se6astian | if he gives green light we are happy to order one from you
|
| 17:34 | se6astian | its open hardware?
|
| 17:37 | danieel | hardware is not yet open, only drivers are aimed to be included to mainline at some point
|
| 17:37 | se6astian | ok
|
| 17:37 | se6astian | thanks for sharing!
|
| 17:37 | se6astian | anything else for todays meeting?
|
| 17:37 | danieel | np, passing the mic back :)
|
| 17:38 | se6astian | otherwise I would conclude todays meeting and say we meet again in two weeks as usual
|
| 17:38 | davidak[m] | great

| 22:36 | felix_ | davidak[m]: how? can you point me to a howto if that exists? and which would be the right image to flash? i have about 0 experience with the beta
|
| 22:41 | felix_ | ah, danieel is also interested in making a good and open source pcie sdi io card
|
| 22:42 | felix_ | i was also thinking about using an artix with 8 gtp and using that with a pcie 2 x4 configuration and multiple 6g sdi inputs and outputs
