15:51
supragya55
hi
15:51
supragya55
seems like you gave me voice
15:51
se6astian
I did
15:52
supragya55
nice...
15:52
supragya55
how did it go at LOreal?
15:54
se6astian
loreal?
15:55
supragya55
RexOrCine said you went to talk to the shampoo guys
15:56
se6astian
lol
15:56
se6astian
yeah, right - sounds very much like rex
15:57
se6astian
I see now what he told you: http://irc.apertus.org/index.php?day=30&month=07&year=2018#90
15:57
se6astian
very sneaky
15:58
supragya55
yes... :)
15:58
supragya55
[Well, they're interested in the camera, and Sebastian. let's say that] :) XD
16:38
supragya55
BAndiT1983, can you give me directions to understand the internal format of ProRes and ARRIRAW for example?
16:38
supragya55
All I can get is whitepapers
16:38
supragya55
No implementation details
16:39
supragya55
Is that even available?
16:40
supragya55
ProRes says there is one, although unofficial at FFMpeg.... is that worth consideration even?
16:41
nmdis1999
Is this for the task sebastian assigned you ? @supragya
16:41
supragya55
that's my gsoc task
16:41
supragya55
basically I have to compare many different ones, and select one and show a working prototype for that
16:41
nmdis1999
before gsoc deadline?
16:42
supragya55
that's the project for the most part
16:42
supragya55
done a large chunk of it in phase 1
16:42
nmdis1999
alright :) good.
16:42
supragya55
although did not go deep into implementations of these
16:43
nmdis1999
you can continue that after evaluation though, shouldn't be much hard now you have done so much stuff, right?
16:43
supragya55
should be
16:43
supragya55
yes
16:43
nmdis1999
nice :)
16:45
se6astian
prores and arriraw are proprietary formats, there is no documentation
16:46
nmdis1999
Good evening sebastian!

17:22
TofuLynx
Hello!
17:22
nmdis1999
Hey :)
17:23
TofuLynx
Yeah, I couldn't talk here, but I could send PM xD
17:24
nmdis1999
and I am for some reason can't send pm, I guess alexML pm is working fine now but now mine is not.
17:24
se6astian
hopefully the spam wave will cool down soon then we can set the channel to the way it was before
17:25

irc meeting time!
18:00
se6astian
welcome everyone
18:00
se6astian
in the usual manner please pm me now and I will put you in speaking order
18:00
se6astian
quick update from me
18:01
se6astian
as you might have noticed the freenode network is currently being spam attacked
18:01
se6astian
https://freenode.net/news/spam-shake
18:01
se6astian
as countermeasure we have switched the channel here to "moderated"
18:01
se6astian
meaning only users with "voice" can talk
18:02
se6astian
we usually just give everyone on the channel voice beside the spam bots
18:02
se6astian
they just come spam links and leave again
18:02
se6astian
hopefully this will stop soon and we can switch the channel back to the way it was before
18:02
TofuLynx
Hello!
18:02
se6astian
but in general it should not make any difference for talk going on here
18:02
se6astian
nmdis1999: please go ahead
18:03
nmdis1999
Okay!
18:04
nmdis1999
Good evening everyone, so last meeting although my tools were ready there was one problem with it. I was reading 8 bit data and thus, my graph was not exactly how they should be
18:04
nmdis1999
so, I changed the code slightly to read 12 bit data (used uint_16t) and everything was good.
18:05
nmdis1999
After getting "right" graphs, and discussing what else I can add in those tools (in future, probably after gsoc) I started writing documentation
18:06
nmdis1999
https://nmdis1999.github.io/ <- this contains a brief overview of tasks and what else I'd like to add it in future, as GSoC allows students to continue working on project if there's room for additions or improvements
18:06
nmdis1999
https://drive.google.com/file/d/1REFGou8_7o2Yvxkw8vaRwVV7ByrSWwWP/view here is documentation consisting of results of three images I used, IT8-chart-5ms.raw12, img.raw12 , darkframe.raw12
18:07
nmdis1999
all these codes and images are present in beta as well as on my github profile (link to which is attached in the above url)
18:07
nmdis1999
so, after getting reviewed I guess everything is done
18:07
nmdis1999
that's it :)
18:08
se6astian
great, many thanks
18:08
nmdis1999
:)
18:08
g3gg0-mobile
joined the channel
18:08
se6astian
2 quick suggestions: 1. please add a preview image of the images you are showing graphs of as well
18:08
se6astian
like the IT8 chart
18:09
se6astian
2. please add axis labels to your graphs
18:09
TofuLynx
Are the graphs more understandable now?
18:09
TofuLynx
Last week there was an hypotesis that it probably was just random noise
18:09
nmdis1999
Okay, I'll do that.
18:09
nmdis1999
@TofuLynx : yes , because I wasn't reading 12 bit data at that time
18:09
nmdis1999
I corrected that
18:09
TofuLynx
Cool! :D
18:09
se6astian
also the label "sample.txt using 1:2" - what does it mean?
18:10
se6astian
maybe you can think of something clearer as label
18:10
nmdis1999
oh..that's text file name, I can change it
18:10
nmdis1999
yes, thank you I will do that .
18:11
se6astian
here are general suggestions by google for the "work product" submission: https://developers.google.com/open-source/gsoc/help/work-product
18:11
se6astian
for all of you
18:11
se6astian
right, TofuLynx your turn!
18:11
TofuLynx
Okk :)
18:12
TofuLynx
So, this week I didnt do very much. My mentor changed the Base OpenCL class to use a OpenCL C++ Wrapper from Khronos
18:13
BAndiT1983
sounds somehow wrong ;)
18:13
TofuLynx
How so?
18:13
BAndiT1983
go on, was just a joke
18:13
TofuLynx
Oh ok xD
18:14
TofuLynx
So, he also made an Interface for Debayer Processors
18:14
TofuLynx
which helped me create the Bilinear Processor
18:14
TofuLynx
I developed a working processor, although it feels a bit cumbersome in the code
18:15
TofuLynx
and then I had a lot of struggles making it fast. I simply wasn't able to make it any faster than it was
18:15
TofuLynx
Maybe I need more knowledge or something, or maybe the problem (debayering) isn't particularly easy to port to OpenCL
18:15
BAndiT1983
main problem is just the instantiation in unit test
18:16
TofuLynx
hmm yeah
18:16
BAndiT1983
in real application, you would create just one instance of ocl manager and then call the debayer class and enqueue them
18:16
TofuLynx
We can solve it this week
18:16
TofuLynx
So, the benchmarks said with the latest optimizations say that it takes 41ms
18:16
TofuLynx
on my GPU
18:17
TofuLynx
(RX 560)
18:17
TofuLynx
which is 10 times slower than the OpenMP version, that is 4ms
18:17
TofuLynx
on my CPU (Ryzen 1600)
18:18
TofuLynx
Also, I have been working on my "final report" which is more about talking about my experience as a GSoC'er
18:18
TofuLynx
I would like to publish it in apertus website or so
18:18
TofuLynx
And now I am working on a gist, with links for everything I did for GSoC, in order to give to Google during this last evaluation phase
18:19
TofuLynx
By the way BAndiT1983 , we can also simplify how unit tests work
18:20
TofuLynx
That's all, se6astian :)
18:20
se6astian
great thanks!
18:20
se6astian
we would love to publish an article about the GSoc results and experiences
18:20
TofuLynx
Cool! :)
18:20
se6astian
depending on how long these articles are we could do one article per person
18:21
se6astian
or one article for all of you
18:21
TofuLynx
Mine is fairly long
18:21
se6astian
last year we did this one
18:21
se6astian
https://www.apertus.org/GSoC-completed-results-report-smart-switching-regulator-article-oct-2017
18:21
se6astian
which was also fairly long and technical
18:21
se6astian
maybe a good middle ground is to do one article with a summary linking out to the full editions for those interested
18:21
TofuLynx
That's true!
18:22
TofuLynx
Good idea
18:22
se6astian
gsoc is almost over again, time went by so quickly....
18:22
se6astian
anyone else here who wants to report?
18:23
TofuLynx
I loved it! It was so great :)

18:31
TofuLynx
How was the rendering made?
18:32
TofuLynx

18:32
TofuLynx
screen*
18:32
se6astian
right that concludes todays meeting. next week will be our last gsoc IRC meeting if I did not make a mistake with the timeline
18:32
se6astian
the rendering was made based on actual CAD models
18:32
se6astian
its a 320x240 TFT
