off to bed now ... have a good one everyone!

Hi Herbert.

great! (channel language is english, jfyi)

meeting starting soon, I am just finishing my dinner

ok ready!

I am

but it looks like we are the only ones

I'm here :)

so GrahamM how are you?

Good, thanks.

With regards to HDMI compatibility, can anything be tweaked easily, or is it all VHDL related?

HDMI is done completely in the FPGA, so the code is VHDL

I have a Blackmagic Video Assist 4K and it won't accept any framerate I choose. It would be nice to use it.

i.e. connect it to a PC and dump the edid tables

Strange, it shows max of 1920x540 60Hz.

it is quite small and upload it somewhere for a start

probably not

please quickly explain the commands

but ddcontrol helps as well, and on recent kernels, the edid is extracted

I will add it to the wiki then

for example, on my linux system, when I check for the graphics card with lspci

which results in a device path under /sys with

there is a drm entry which contains per card and per port subdriectories

and the full path to the edid for the first port here is:

in the same dir is a processed version which lists the detected modes in 'modes'

GrahamM: are you still with us?

great

thanks

wiki?

decode them as well somehow?

but a decoded version is enough to work with

how can we decode it?

can you paste me the result please

Bertl, the email was rejected.

uploaded the attachment to the above link

is that not the case?

yes, here is the output from edid-decode:

so the reason it doesn't work with the typical modes seems to be that it simply doesn't do 1080p60 as advertized (VIC blocks) but only supports the detailed modes which are not really anything we currently produce

adding to wiki

all the clock rates given there suggest that 1080p30 is somewhat the maximum you can do

can it take 4K signals only via SDI?

It accepts 1080p60 from my PC. I have used a 4K camara with no problems.

added to wiki

what was the process to capture this edid now?

Extended HDMI video details: HDMI VIC 0 3840x2160@30Hz HDMI VIC 1 3840x2160@25Hz HDMI VIC 2 3840x2160@24Hz HDMI VIC 3 4096x2160@24Hz

I have a meyer optic lens that i can get sent to apertus if i get the VAT number, then you can give it to me along with the camera once that is done

comradekingu: what kind of lens is it?

GrahamM: the TV might be extra picky

se6astian: Trioplan f2.9/50 and Primoplan 58 f1.9

hi, just sent a request for edit access for the current flyer google doc

done

They are in nikon mount

and what do you need the VAT number for?

good night

Because then i dont have to pay that

what is the actual ZIF socket type for the sensor?
