| 17:59 | se6astian | meeting starting soon, I am just finishing my dinner
|
| 17:59 | se6astian | give me a few more minutes :)
|
| 18:07 | se6astian | ok ready!
|
| 18:07 | se6astian | so who is here for the meeting?
|
| 18:07 | Bertl | I am
|
| 18:08 | se6astian | great :)
|
| 18:09 | Bertl | but it looks like we are the only ones
|
| 18:09 | Bertl | in which case I suggest to spend the time better :)
|
| 18:09 | GrahamM | I'm here :)
|
| 18:09 | Bertl | ah, no, we got one more, great! :)
|
| 18:10 | se6astian | so GrahamM how are you?
|
| 18:10 | se6astian | what did you work on recently?
|
| 18:11 | GrahamM | Good, thanks.

|
| 18:18 | GrahamM | With regards to HDMI compatibility, can anything be tweaked easily, or is it all VHDL related?
|
| 18:19 | se6astian | a lot can be tweaked
|
| 18:19 | Bertl | HDMI is done completely in the FPGA, so the code is VHDL
|
| 18:19 | Bertl | but it is designed in such way, that you can control it from the cpu side
|
| 18:19 | se6astian | https://wiki.apertus.org/index.php/AXIOM_Beta/AXIOM_Beta_Software#HDMI_Output
|
| 18:20 | Bertl | i.e. a number of currently memory mapped registers control the various aspects
|
| 18:23 | GrahamM | I have a Blackmagic Video Assist 4K and it won't accept any framerate I choose. It would be nice to use it.
|
| 18:24 | Bertl | probably the first step is to figure out what it 'claims' to accept
|
| 18:24 | Bertl | i.e. connect it to a PC and dump the edid tables
|
| 18:26 | Bertl | once you know that, you can start building a suitable mode
|
| 18:35 | GrahamM | Strange, it shows max of 1920x540 60Hz.
|
| 18:36 | Bertl | simply dump the entire EDID to a file
|
| 18:36 | Bertl | it is quite small and upload it somewhere for a start
|
| 18:36 | se6astian | do we already have a section in the wiki that covers how to do that?
|
| 18:36 | Bertl | probably not
|
| 18:36 | se6astian | I think it would make sense to start collecting EDID from multiple devices
|
| 18:36 | se6astian | please quickly explain the commands
|
| 18:37 | Bertl | definitely
|
| 18:37 | davidak | joined the channel |
| 18:37 | Bertl | the simplest way is probably with monitor-edid
|
| 18:38 | Bertl | but ddcontrol helps as well, and on recent kernels, the edid is extracted
|
| 18:40 | se6astian | GrahamM: can you please run both commands and upload the output
|
| 18:40 | se6astian | I will add it to the wiki then
|
| 18:40 | se6astian | I think we can officially end todays team meeting and deal with HDMI documentation instead :)
|
| 18:41 | Bertl | for example, on my linux system, when I check for the graphics card with lspci
|
| 18:42 | Bertl | I see that the card is at bus-id 03:00.0
|
| 18:42 | Bertl | which results in a device path under /sys with
|
| 18:42 | Bertl | /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:03\:00.0
|
| 18:43 | Bertl | there is a drm entry which contains per card and per port subdriectories
|
| 18:43 | Bertl | *subdirectories even
|
| 18:43 | Bertl | and the full path to the edid for the first port here is:
|
| 18:43 | Bertl | /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:03\:00.0/drm/card0/card0-DP-1/edid
|
| 18:44 | Bertl | in the same dir is a processed version which lists the detected modes in 'modes'
|
| 18:45 | Bertl | here I found a python script which seems to get the data from xrandr

|
| 18:53 | se6astian | GrahamM: are you still with us?
|
| 19:01 | GrahamM | Yes.
|
| 19:04 | se6astian | great
|
| 19:15 | GrahamM | Sent it by email to you both.
|
| 19:24 | se6astian | thanks
|
| 19:28 | se6astian | Bertl: how should we collect them
|
| 19:28 | se6astian | wiki?
|
| 19:28 | se6astian | github?
|
| 19:28 | se6astian | decode them as well somehow?
|
| 19:31 | Bertl | I would definitely store the binary somewhere
|
| 19:32 | Bertl | but a decoded version is enough to work with
|
| 19:32 | Bertl | (and can be easily shown on the wiki)
|
| 19:41 | se6astian | how can we decode it?
|
| 19:43 | Bertl | edid-decode
|
| 19:44 | se6astian | can you paste me the result please
|
| 19:44 | Bertl | haven't got the edid data yet
|
| 19:45 | GrahamM | Bertl, the email was rejected.
|
| 19:47 | se6astian | i ll upload it
|
| 19:48 | se6astian | https://cloud.gerade.org/index.php/s/T6HQJymJLn5HtZu
|
| 19:50 | GrahamM | I have sent another email to you both.
|
| 19:54 | se6astian | uploaded the attachment to the above link
|
| 19:54 | se6astian | I thought decode actually makes it human readable?
|
| 19:54 | se6astian | is that not the case?
|
| 19:55 | getzi | left the channel |
| 19:57 | Bertl | yes, here is the output from edid-decode:
|
| 19:58 | Bertl | http://pastebin.com/raw/6qzxAziG
|
| 20:00 | Bertl | 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
|
| 20:00 | se6astian | thanks
|
| 20:00 | se6astian | adding to wiki
|
| 20:01 | se6astian | what model is it exactly GrahamM ?
|
| 20:01 | Bertl | all the clock rates given there suggest that 1080p30 is somewhat the maximum you can do
|
| 20:02 | se6astian | strange, its called "Blackmagic Video Assist 4K" so it should do more
|
| 20:02 | se6astian | can it take 4K signals only via SDI?
|
| 20:03 | Bertl | it advertises four extended HDMI modes
|
| 20:03 | GrahamM | It accepts 1080p60 from my PC. I have used a 4K camara with no problems.
|
| 20:04 | Bertl | so what settings does your 1080p60 PC setup produce/use?
|
| 20:06 | se6astian | added to wiki
|
| 20:06 | se6astian | https://wiki.apertus.org/index.php/HDMI_EDID_Archive
|
| 20:06 | se6astian | what was the process to capture this edid now?
|
| 20:06 | se6astian | I want to also add that to the wiki page
|
| 20:06 | se6astian | Extended HDMI video details: HDMI VIC 0 3840x2160@30Hz HDMI VIC 1 3840x2160@25Hz HDMI VIC 2 3840x2160@24Hz HDMI VIC 3 4096x2160@24Hz
|
| 20:14 | GrahamM | According to the AMD settings, 1080p60 *email address removed*4K displayed this OK.
|
| 20:15 | comradekingu | 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
|
| 20:16 | GrahamM | I tried the Beta on a Samsung 1080p TV and it would only accept 1080p60, it would not display 25 and 50.
|
| 20:16 | se6astian | comradekingu: what kind of lens is it?
|
| 20:17 | GrahamM | Got to go for now, will be back later.
|
| 20:18 | Bertl | GrahamM: the TV might be extra picky
|
| 20:19 | se6astian | right, thanks for pushing this GrahamM, stay on it :)
|
| 20:38 | comradekingu | se6astian: Trioplan f2.9/50 and Primoplan 58 f1.9
|
| 20:39 | comradekingu | p r o d u c t i o n v a l u e for the teamtalks. Just need amiga toaster and everything will be just so
|
| 20:53 | intracube | hi, just sent a request for edit access for the current flyer google doc
|
| 20:54 | intracube | se6astian: ^ (or whoever owns the doc)
|
| 20:59 | se6astian | done
|
| 21:00 | intracube | danke
|
| 21:01 | comradekingu | They are in nikon mount
|
| 21:01 | comradekingu | or nikkor maybe it is
|
| 22:07 | ItsMeLenny | joined the channel |
| 22:12 | se6astian | comradekingu: what do you envision we do with those lenses?
|
| 22:12 | se6astian | and what do you need the VAT number for?
|
| 22:14 | se6astian | off to bed
|
| 22:14 | se6astian | good night
|
| 22:16 | comradekingu | se6astian: film the team talks
|
| 22:16 | comradekingu | Because then i dont have to pay that
|
| 22:17 | comradekingu | I think they would be well suited to show the capabilities of the sensor. Sure are expensive enough
|
| 22:26 | intracube | what is the actual ZIF socket type for the sensor?
|
| 22:26 | intracube | if I remember correctly, it was an intel 386 type?
