Bertl: http://paste.linux-vserver.org/40132 does the exposure() function returns ns ?
01:20
FergusL
given the 1e9
01:20
FergusL
but that's unclear to me...
01:21
FergusL
if you've got a moment to explain, based on what the doc says: Exposure time (ns) = [(Exp_time-1) x (reg85+1) + 1701] x LVDS_CLK_P/N-period x #bits

se6astian
good day
10:56
carsonau
how are you?
10:57
carsonau
apologies in advance, not quite familiar with using IRC
11:05
se6astian
hi carson
11:05
se6astian
good good
11:05
se6astian
but unfortunately I have to leave right away now for lunch
11:06
se6astian
will you still be here afterwards to chat?
11:06
se6astian
you can try in the meantime if Bertl is around, he normally lives more the US timezone so it might take a bit of more time until he is up
11:08
carsonau
ahh right. timezone's going to be of a bit of a problem. I'm off to bed just now! (Sydney, Australia timezone)

HI se6astian, in case you haven't noticed
12:19
FergusL
I pushed to the repo. tell me if there is anything you notice
12:22
se6astian
great thanks
12:22
se6astian
you know there is a demo register dump in the repo to test it right?
12:23
FergusL
that's the only one I tested with
12:23
FergusL
I need to test with some other which I exactly know the exposure time, that's the first test I'm doing
12:25
FergusL
se6astian: is there some more coding like this to do in some area ?
12:26
se6astian
if the metadata reader is finished we could do something similar for the PHP that runs on the camera
12:27
se6astian
https://twitter.com/ApertusOSCinema/status/423806487501086721/photo/1/large
12:29
se6astian
I have not commited the php code itself yet but I can do that soon
12:30
FergusL
that erh... that is *on* the camera root@...114 is a shell on the camera itself ?
12:31
se6astian
webserver on the camera yes
12:31
FergusL
ha yes, apparently, sorry didn't read the tweet that comes with i
12:31
FergusL
t
12:32
se6astian
a bit more difficult to test then without a camera but we should be able to find a way to do that as well
12:34
se6astian
like we can set up a fake register source on the actual apertus webserver for example
12:35
FergusL
I don't know php though but I'm sure I can understand and contribute on something that is already partly done, like i've done for the reader
12:35
se6astian
great!
12:36
FergusL
and I'd like to learn some web dev too
12:36
se6astian
perfect opportunity then
12:40
FergusL
se6astian: it's based off bootstrap ?
12:41
se6astian
yes
12:41
FergusL
so is the website anyway
12:41
se6astian
yes
13:01
FergusL
Okay I think I can confirm the exposure function works fine
13:02
FergusL
"72[23:0] Exp_time: 40960 422.765 Exposure Time (ms)" for scene_lowlight_422ms_c.raw16, makes sense
13:03
se6astian
looks good yes
13:07
FergusL
the sensor is detected as monochrome sensor in the registers
13:09
se6astian
interesting, lets look into that, maybe its missconfigured on the camera defaults atm
13:10
FergusL
the issue can't be in the C code ? :) or shall I double check ?
13:10
se6astian
maybe :)
13:10
se6astian
please check
13:21
FergusL
se6astian: code is fine
13:21
FergusL
it's for interleaved read out only though
13:22
FergusL
so nothing to worry about to much I think
13:23
se6astian
I see, well lets keep it in the back of our heads, I want to test the HDR modes soon
13:23
FergusL
ok
13:25
FergusL
I'd like to shift Description by one \t right to increase readability
13:33
se6astian
good idea, please go ahead
13:45
FergusL
beautiful !

opusprod
first congratulations for your projet :
13:49
opusprod
beautiful ideas
13:49
opusprod
i'm french , pardon me if i am not 100% correct with my english
13:50
FergusL
je suis français aussi, je traduirai si besoin donc hésite pas si tu as des mots qui manquent !
13:50
opusprod
ha OOk super alors
13:53
opusprod
I' a graphic designer specialist in 3D vizualisation and animation
13:54
opusprod
and i'd love to participate to your Axiom project
13:54
opusprod
if you need to make 3D photorealistic renders
13:54
guesst
oh, no renders, make product :)
13:55
opusprod
hahaha
13:55
guesst
otherwise you end up like blackmagic :P
13:55
opusprod
true in a sense
13:56
opusprod
i've done some 3D vizualisation of the BMCC
14:00
opusprod
i guess that the priority is finishing the prototype
14:01
FergusL
maybe some help can be needed now or later for 3D visualisations, I don't know
14:01
opusprod
but if you need some help for the artworks, i' an here
14:03
se6astian
check your pm view opusprod
14:10
FergusL
ok; pushed the last changes se6astian
14:13
se6astian
thanks!

FergusL, I just committed the PHP scripts, etc. to github
17:31
se6astian
https://github.com/apertus-open-source-cinema/alpha-software/tree/master/misc_scripts_and_utilities/webserver_root
17:31
FergusL
nice !
17:31
se6astian
its a bit messy at the moment but I am fine answering any questions to help you get an overview
17:31
FergusL
se6astian: php is
17:32
FergusL
se6astian: php is your thing usually ? I mean that's what you know the most
17:32
se6astian
yes, the platform I develop in most regularly
17:33
FergusL
I see
17:34
FergusL
php is server side only right ? does it help in the generation of html ? I've encountered php already and worked my way around small glitches but never written any lign of it, I don't actually know what it *is* exactly
17:34
FergusL
I can rtfm as well
17:36
se6astian
yes, server side only, it generates html as output
17:40
FergusL
I get it
17:40
FergusL
looking at the files there
17:41
FergusL
just being curious, php is generally registered as a module of some sort by the webserver, like in apache iirc
17:42
FergusL
so when serving pages like foo.bar/registers.php it is first processed by php, that outputs valid HTML code that is then sent to the requesting client ?
17:43
intracube
joined the channel
17:47
se6astian
yes
17:49
FergusL
I think I get it, and I think I like it !!
17:49
FergusL
what's the next milestone for this part ?
17:52
se6astian
I just compiled your latest commits to the metadatareader
17:52
se6astian
very nice
17:52
FergusL
cool
17:53
se6astian
I love the "--" for blank values, makes it much more readable
17:53
FergusL
as I've noted, the time calculations are working !
17:53
se6astian
great work
17:53
FergusL
thanks :) I'm really happy to have brought some help
17:54
se6astian
I am just reading through the output
17:54
se6astian
76[23:0] Exp_kp1: 0 171799 Exposure Time (ms)
17:54
se6astian
what does the 171799 mean?
17:55
FergusL
well it is the result of the calculation when all the arguments are at 0
17:55
FergusL
"72[23:0] Exp_time: 20480 211.411 Exposure Time (ms)" is the only meaningful line, which is correct since it was a standard exposure
17:55
FergusL
or did I get it wrong ?
17:56
se6astian
no I think the formular is right
17:57
se6astian
but I guess for the kneepoint 0 means "disabled"
17:58
FergusL
hm, yes, maybe adding a switch there ? case 0 : Disabled else prints the value
17:58
se6astian
good idea
17:59
FergusL
though it doesn't mean disabled as per the datasheet unless I missed it
17:59
se6astian
I just renamed the Exposure times for the knee points to "Knee Point 2 Exposure Time"
17:59
FergusL
because when in multiple slope mode, you might be able to set kp at 0, it won't result in something interseting but it will not be disabled
18:00
se6astian
I see
18:00
FergusL
so I don't mind leaving non-sense values in the output as long as they are "right"
18:00
se6astian
lets leave them for now, when I take some test images with the HDR mode we can take another look at what the proper values mean
18:00
FergusL
ok
18:01
FergusL
good idea
18:01
FergusL
can you take a look at line 523
18:01
FergusL
for register 116, I added a comment
18:02
FergusL
I think "mult" is for multiple exposure mode, to have different values... but maybe not
18:02
se6astian
in that case it means "muliplier"
18:02
se6astian
*multiplier
18:03
FergusL
ha !
18:03
se6astian
and also applies to non hdr modes
18:04
FergusL
how do you know that ? simply guessing ?
18:04
se6astian
by testing :)
18:04
se6astian
and a bit of guessing
18:04
FergusL
got it
18:05
se6astian
first I thought the values for 116 in the datasheet contain a typo
18:05
se6astian
since its 3 for both 10 and 12 bit mode
18:05
FergusL
well maybe update (or not) the description and remove my comment then !
18:05
FergusL
yes I saw your comment
18:06
se6astian
but if you look at the bits: 1 = 0001, 3 = 0011 in front of the ADC_range it seems like its actually a single register
18:07
se6astian
let me post the output on twitter as development update now :)
18:08
FergusL
sure !
18:10
se6astian
done
18:10
se6astian
do you have a twitter account?
18:11
FergusL
yes, logging in now to retweet !
18:11

se6astian
username?
18:12
se6astian
thanks
18:14
FergusL
thanks for the mention !
18:16
se6astian
credits are the only currency I can pay you in atm :)
18:17
FergusL
I must confess I'm proud of it, it's an important achievment to feel you've contributed something meaningful, regardless of how much meaning it has
18:18
FergusL
I got a recommandation to follow Digital Bolex when I started following Apertus on twitter hah
18:18
FergusL
I wonder what they are at now
18:19
FergusL
didn't we have some conversations with Joe some time ago ?
18:19
FergusL
must have been a year
18:19
se6astian
a brief one a long time ago
18:21
FergusL
I never understood why so much empashis on the aesthetics
18:21
FergusL
we're doing the same... but only in 3D models :)
18:24
se6astian
well I do think its important to like a product not just because of its features, if there is an emotional connection it makes it more special
18:25
FergusL
yes... that's true as well
18:25
se6astian
latest viewing stats of today: 1082 unique visitors to main website and minisite together
18:26
FergusL
increased since yesterday
18:26
se6astian
and the day isnt over yet :)
19:35
FergusL
so se6astian, what about that php ?
19:45
se6astian
yes, it would be great to have the same amount of register explanation and decoding as on the metadata reader
19:46
se6astian
currently I just copy/pasted in all register names from the datasheet
19:46
FergusL
ha yes I see
19:46
FergusL
maybe displayed differently though ?
19:46
FergusL
because as I've seen it allows writing to it, does it ?
19:46
se6astian
yes
19:46
se6astian
I am open for all new ideas
19:47
FergusL
well maybe sorting, grouping things together
20:00
se6astian
yes the grouping together works with the button at the top
20:00
se6astian
where you select "topic"
20:00
se6astian
and then only get the registers that are relevant in that context
20:00
se6astian
like exposure time, kneepoints, etc in "HDR"
20:01
se6astian
ok gotta go afk for a bit, let me know if you have any questions, etc. in a PM
20:10
FergusL
understood se6astian, going to play a bit with php to understand how it works
