felix_: I would suggest to restore the backup (you or somebody hopefully did) from/at 34c3 because the 'normal' SD image will not work with the SDI plugin
01:43
Bertl
regarding danieel's pcie sdi card: as far as I understood, there are no plans to make it open hardware, only open source the drivers at some point (aimed for mainline inclusion)
01:44
Bertl
(please correct me if I got that wrong)
01:52
felix_
on the sd card image: it would be good if whoever made the backup from that could send me the image
01:53
felix_
on the pcie card: i don't really care about the pcb artwork not being open source; full schematics and open source gateware would be nice though. working on the second one at the moment ;)
01:59
Bertl
I think Apertus° cares ;)
01:59
Bertl
regarding SD image: how about getting a copy from the other Beta?
02:02
felix_
the other one isn't here yet
02:03
Bertl
where is it?
02:06
felix_
i don't see much benefit of having the pcb design completely open other than "because we can", but i'm not opposed to the idea. not havin the designs open source probably won't prevent clones, so that't not a very good argument against publishing that and i can't really think about any other good argument against. i also don't have a good pro argument
02:07
felix_
Bertl: _florent_ has the second one; he'll arrive at the weekend
02:07
Bertl
the pro argument is that it can be reproduced and modified without putting in extra work to reverse engineer it
02:08
Bertl
means, no vendor lockin, no restrictions on modifications
02:09
felix_
ok, being able to easily modify the device is a pro argument. building your own device yourself is probably more expensive than just getting an assembled unit and requires tools most people don't have
02:10
Bertl
yes, but let me make an example here: let's say we use a proprietary card from vendor XY with excellent open source drivers we incorporate in our 'product'
02:11
Bertl
everything is fine, till one day, vendor XY goes bankrupt or decides to not build any more of those cards
02:12
Bertl
the result for us is that we either have to reverse engineer the card to build our own version or to switch everything to a new card, given that there is one available
02:12
felix_
yeah, that will be a problem. the beta uses a commercial module though where i'm not sure it the pcb artwork is public...
02:13
Bertl
which module are you referring to?
02:14
felix_
the zynq board
02:14
Bertl
the layout for all revisions is available for download
02:14
felix_
ah, nice
02:14
Bertl
also the bom list
02:15
felix_
ok, didn't know that
02:15
Bertl
and of course the schematic
02:15
felix_
yeah, i've alerady looked in the schematics
02:22
Bertl
regarding SD image: maybe _florent_ can make a copy dd/xz and make it available for you before the weekend
02:23
Bertl
note that when you have both cameras running with the same SD image, you want to modify the MAC address for one of them (on the SD card) if you want to put them in the same network
02:23
felix_
i don't depend on that at the moment, but yesterday i wanted to show the setup to someone at the timvideos hackfest
02:46
mithro
Bertl: So - it would be really awesome if we could get the AXIOM camera into the LCA video recording set up here
02:47
mithro
Bertl: What is needed to get video (say, raw 720p30?) streaming out the Ethernet port on the AXIOM?
02:52
Bertl
a real time video compressor which can reduce the data to 500Mbit/s or so?
02:55
Bertl
720p30 is 27 megapixel per second, so assuming 24bit RGB, it could almost work, for raw, at least a 2:1 compression is required
02:56
felix_
iirc there's mjpeg encode support in the hdmi2usb project
02:57
Bertl
in any case you need some kind of streaming server which can send out the data at the given rate
02:57
felix_
but just using either the hdmi or the sdi output will require much less work
02:57
felix_
for getting it working for the conference
03:00
Bertl
yes, definitely

davidak[m]
felix_: i flashed the image and don't made a backup before, since it is mostly the same as the other beta
05:29
davidak[m]
the HDMI image don't work because it is too old for the hardware
05:31
davidak[m]
sadly we don't automatic image building yet
05:31
davidak[m]
do you know who flashed the two betas initially? the person should have the right image
05:32
davidak[m]
or just clone the sd card from the other beta
05:34
felix_
uh, i neither know who flashed that not their nicknames
05:35
davidak[m]
probaply Bertl
05:35
davidak[m]
but i don't know. maybe mithro knows?
05:36
felix_
ah, yeah, Bertl_zZ built the right image. i thought you meant at 34c3
05:37
felix_
probably the newest version from here http://vserver.13thfloor.at/Stuff/AXIOM/BETA/FLORENT/
05:43
davidak[m]
felix_: that seams to be the bitstream for the SDI FPGA
05:43
davidak[m]
not the camera firmware image
06:01
felix_
that should be the image for the axiom side
06:48
davidak[m]
maybe for the FPGA
06:49
davidak[m]
but it's not the image for the sd card. it's too small
06:49
davidak[m]
that was 16 GB!
06:51
felix_
ah. i meant the image that gets shoved into the device that is used to configure the fpga fabric
06:54
davidak[m]
ok. then that might be right
06:55
davidak[m]
isn't that included in the firmware image and get's flashed when the kick script is executed?
07:06
felix_
should be, but i don't know for sure

danieel
Bertl_zZ: / felix_ : the bankrupcy issue is solved by *USING STANDARDS* so that you can use any other vendor's card. There is nothing really proprietary in SDI

Bertl_oO
danieel: good to hear that you plan to write your drivers for other vendor's cards as well!
10:12
danieel
Bertl_oO: eh?? it will have V4L2 so you dont need to change your app, if other vendors follow the standard ways :)
10:14
Bertl_oO
and as you already stated, they don't so that doesn't help either
10:17
danieel
being not compatible is their choice, not mine.
10:17
danieel
we could not find any with arm drivers, so we built it this way
10:18
Bertl_oO
do you provide schematics to your card?
10:23
danieel
what for? I except it might need NDAs
10:24
Bertl_oO
