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

good evening

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

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

can you also report what Bertl_zZ was working on?
17:22

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

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

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]

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
