#apertus IRC Channel Logs

meh

now i got a mail, about 5 minutes later

the code didn't work

se6astian: can we delete the "test" board? https://wiki.apertus.org/index.php/Beta_Main_Board

morning folks!

off for now ... bbl

hi

Hi everyone!

yes

Source/CinemaDNGDecoder says otherwise, what about processingtest?

ah, you mean the old project, i should remove it, was used as test for DNG, till i'Ve implemented new structure for OC some years ago

that is what I asked 2 days ago... I felt stupid... :)

i had no time to get online, had to pack for my move to new city

imageprovider.cpp is one of important classes

TIFF DNG MLV

what about OpenCine/DataProvider? saw LibRawDataProvider there

FFMPeg is disabled as you earlier notified...

OpenCine/DataProvider

this is an old project, have also to be removed

current ones are, occore, ocui, ocbackup, processingtest and oclauncher

what about raw images? analogous to librawdataprovider in the new working project? the place where plugin development should root from?

i could extend the imageprovider, so it loads further files from DNG folder, because till now it was used for single frames

also we can avoid debayering at the moment, if we load just known pixels

DNG folder? DNG sequence?

avoid debayering at the moment did not understand this bit...

to accelerate playback, we could load just every second pixel and avoid empty between them, this depends on R,G or B order/layer

but then it would be grayscale?... only one channel

nope, it would be colored

if we have RGGB, then you would load every 1,3,5 and so on, this would be the red one, at the end of the line (width) you would jump the same amount of pixels in width to the 3rd line and continue

something you referenced earlier... like Aftereffects preview..

something like that

this for RAW ?

this approach came from Bertl_oO by the way, he mentioned it long time ago, but i had no time to implement it

this is for bayer sensor images, so DNG

ok... so what exactly is difference in DNG and RAW12/RAW14?

DNG is an extension to TIFF and holds many infos about the image

metadata... which raw12 dont

okay

focussing on that and MLV first, as MLV golds DNG inside the container

was not happy with FFMPEG implementation of the decoder and created one myself, also a bit as excercise to see how it work internally

for MLV it would also be interesting to load the frame data quickly and bypass the header of all files after the first one

the code is not big and works fine, but for one image at the moment, have still to do the sequence loading

if you need more infos or support just ask

regarding MLV and DNG... difference?

don't remember, to be honest

had other tasks at apertus, so opencine wasn't maintained for some time

https://www.magiclantern.fm/forum/index.php?topic=7122.0

e.g. you can allocate several 200mb pages and use the allocator to place the data quickly, without the need to search for free segment in RAM

or here it is visual -> https://github.com/mtrebi/memory-allocators#pool-allocator

no problem, just ask if you need something

BAndiT1983: am I wrong to say that TIFF loader currently doesn't concern much with Header data? seems like it's only referenced to get IFDOffset.

it walks through the tags and extracts the infos it needs, like width, height and so on

nothing fancy... like compression level etc?

hi TofuLynx, how is it going?

I just built openCine

I have postponed the openGL stuff

first I want to get to know how OpenCine works and stuff

OC doesnt detect my pendrive

it should usually, have you started OCBackup, just asking as there was some confusion, have to remove old projects from the repo or at least move to archive folder

skips can be done by BayerFramePreProcessor::Process(1)

can I know why

https://sourcemaking.com/antipatterns/software-development-antipatterns

e.g. SHOODAK etc.

why two different codes for same thing?

yes, this class would be used for first data split

TofuLynx, i suggest exploring OCCore

TofuLynx, depends on what you want to start with

if you want to check why it does not find your pendrive, then check drivemanager, there are 2 implementations which are compiled depending on your OS, linux or win

my pendrive is recognized as hard disk drive on my drive manager

supragya, OCcore is the core of OpenCine?

TofuLynx, yes but consult BAndiT1983 I sugget

Ok thanks :P

questions?

yes, but i have to take a look first how i have done it :D was long ago

Any hint where is it?

https://github.com/apertus-open-source-cinema/opencine/tree/master/Source/OCcore/Platforms/Linux

used virtual cd in linuxmint, was done with native tools in distro without requiring extra packages

hmm

I can try it

but why is it restricted to media?

April Fools Joke video this?

no, the videos clips at the end, with the girl and last one with the 3d printed model

BAndiT1983, do you suggest I start with plugin already? [maybe we can add skip mode there, just try if it works for you, we can discuss your code after you have done it]

if you are comfortable with the code, you can also start with the VP plugin

But dont think you could just use a path chooser?

is this?

yes, there are 5 clips of MOV, but i would suggest DNG first, as FFMÃœEG is siwtched off

just to repeat it, switched QtAV/FFMPEG off, as there were build problems under windows, so i wanted to get the process straight, before enabling it again

maybe point people to a page which builds FFMPEG and provides includes and libs, which have to be put in special folder in OC in windows

when I get home later this afternoon I will check it

Understood!

no problem, just showing up the directions, ask if you need anything

wait a second, will switch from PC to phone

there is no pre-fixed, processingtest uses bilinear one

BilinearDebayer* debayer = new BilinearDebayer(*_image.get());

see processingpresenter.cpp in processingtest, line 41

if you disable the line with debayer->Process(); then the image would be plain

supragya, try to create a simple VS script first, to get also comfortable there

get a video clip and try to provide it through VS to some video editor

all the others are done... the only optional remains is beta-axiom software to run the debayer on...

does that count? or does it have to be latest commit?

running it on beta software is just a bonus point

it was just some days ago

[get a video clip and try to provide it through VS to some video editor] - I will try SVP...

have contacted the guy who has created newer scripts and trying fix them with him, but have to get logs from errors they show

supragya, sounds good, which OS?

15.1

why 15.1?

*them

BAndiT1983: just saw links at https://lab.apertus.org/T872 for review... am i still allowed to change my codes? when will reviews be?

so is it being reviewed?

will be soon, i have just taken a quick look so far

K sure...

If its no problem

2 i guess

oh :/

https://lab.apertus.org/T872

phabricator*

haven't found supragya in Lab, so placed IRC nick

It would be better for the community if there was people interested to contribute in the other two challenges, dont you think so?

the FPGA one and...

the other 3 challenges

last year there were many more applications, don't know what this year is different

maybe challenges are spooking people off, but we have to be on the safe side, after a bit of fiasco last year

i think the challenges are great!

I learned a lot with it!

so that is seen in challenges

and they keeped up with the challenges?

can't say, am not up to date on FPGA, and so on, ones

Okk! :)

people can attend the project also outside of gsoc - that is how it should be I guess

I think it is good to sort of "advertise" the organizations

i found the project on blendernation.com 4.5 years ago, seen OC mock-ups and wrote an e-mail

otherwise... it's just another job

BAndiT1983... who was working on OC then

hmm, how many years ago

gosh it's midnight here already... lost track of time

Midnight? wow

where are you from supragya, may I know?

hmm

Nice!

see this ./prepare_all.sh: line 133: cd: /home/supragyaraj/PiNG12RAW/axiom/axiom-beta-qemu/external/ext4fuse: No such file or directory

Something went wrong?

OC change direction a couple of times, if you look at the commit list, then you will see, that not many other commits were done, generally people do not like C++, the hype nowadays is web stuff, but it's still not fast enough for such things

ext4fuse?

what is it used for in your project?

no, it's just update on the log i am creating

and what's your area of work?

uh

your specialization or anything

i'm a full-time software developer

HTML, CSS etc... only few I like Django for ex

i'm waiting more than writing code, as the code has to be deployed often

if you google him, you will know ;) - did you search me? :)

google can be very frightening

wow bandit xD

while preparing for gsoc it is often important to get more info to learn the background of people, as without personal contact it can be difficult to get the details

Hope you have the same taste in videogames

i'm not judgung by that, no worries ;)

but i would be confused, if it were my little pony or similar :D

we should turn the discussion to the main stuff after that

don't want to junk up the main chat channel

supragya, have also visited your homepage some days ago, wondered about TensorFlow logo, but have not found any traces of that in your repos

what... I am embarased

Not touched it for quite sometime

it's just a placeholder... TensorFlow

https://www.google.de/search?q=cuda+logo&client=opera&hs=uDl&source=lnms&tbm=isch&sa=X&ved=0ahUKEwidzZnnnsTZAhWEJFAKHenEBugQ_AUICigB&biw=1920&bih=1008

you can go with black one or paint it orange

or even make cuda orange and nvidia letters black

https://www.google.de/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=2ahUKEwiwmdiSn8TZAhXSh7QKHeB-Ae0QjRx6BAgAEAY&url=https%3A%2F%2Fnvidianews.nvidia.com%2Fnews%2Fnvidia-dramatically-simplifies-parallel-programming-with-cuda-6&psig=AOvVaw13v0U2VuBmnW9nAH1Fqi4C&ust=1519757260651211

when i've talked to a colleague about it, he suggested to add self-learning module, which can estimate from learned PCBs which are bad and which are good

so tensorflow jumped to my mind

that you went throught the website

tell me about the work at apertus

relax, i just wanted to check what your interests are

not many people are using C++ nowadays, at least not in my area

you just need some framework like bootstrap, to make this task simpler, no need to go for full-blown processing pipeline

I guess so

http://sass-lang.com/

it's not tensorflow currently, but opencv, let me get the link to the lab task

but the problem is still that with sass you have to write browser specific code

webkit not used everywhere

some older screenshots there, new version, not uploaded yet, has a webpage where you can drag an image to the drop field, it will be sent to the node.js server, processed by python script (maybe c++ later for performance) and pushed back to the webpage automatically

used LESS SASS SCSS

not much

bur for that i've used gulp and gulp-pump

alright, then please upload it to the task

https://lab.apertus.org/T737

Bandit, regarding that research about me you made, I think you didn't find a lot of information at all about me, I guess

no, not as comment, please pack it in a text file

Oh ok

It's that I don't have any stuff about me online at all, except on LinkedIn

Roblox? xD

TofuLynx: someone is spying XD..

Yeah steam is surely me

Anyways if you want any info, specially info that actually is interesting for you as mentor

Really? xD

I don't know any football player called Cláudio Gomes

supragya, you can find the name at github

but let us go back to the professional stuff

Portugal :)

then se6astian has to delete some stuff ;)

but he accepts only big amounts of money

thanks for the log, supragya, forwarded it to the developer of the QEMU scripts, will try to get logs from LinuxMint also

found it already ;)

I get money for deleting logs, what?

se6astian takes money?

for deleting compromising logs ;)

as if we have nuke codes shared here

what is "compromising"?

and actually Bertl_oO is the one who could delete stuff in the logs

oh, then you need even more money

xD

don't know if true, but there are several stories about people twittering photos of their new credit card, gues what happens next

Ahaahah that's so true

hi everyone !

Hi max_bxl, long time no see!

(guess i should not be the one welcoming)

Hey max!

Huh

*you built

None I think

Just that 2 commented lines

What older scripts?

yes.. the latest one

this one -> https://github.com/apertus-open-source-cinema/axiom-beta-qemu/tree/351364045b0e0c59caaa496499da25c81efe528d

it should be sufficient - challengewise?

try to use kernel 4.6, it had less problems, according to docs

just as a test if the student can run this advanced stuff

will try a bit more..wont fret over it

And follow cautiously the instructions

It was irritating to me to get it to work but it was just because it was 4.9 kernel, I think you will do fine :)

supragyaraj, just a quick suggestion, create a simple application which uses OCcore

as simple as console app, so you can test the interaction

thanks for the heads up

because most extensions are my part, as preparation for gsoc, they should allow the student to progress more smoothly

prepared myself more or less thorughly last year and wrote Go application before mentoring started, so i know how the app could look like

Hmm is somewhere a kind of briefing about OC progress?

wiki.apertus.org, but i had no time to get it up to date, maybe we can approach it together step by step

hey, i haven't chosen the name for it

😂

i see a square with 4 zeroes

Ok sorry xD

i've thought that it is the icon of a go board

:D

maybe you have an extension for that

no... it came bundled with manjaro.. don't know if plugin there

however i do see that boxes from time to time

I use hexchat too :)

I have a desktop computer with windows 10, waiting to have some money to buy a second ssd to put Linux on it

And I have a laptop with Linux, where I do most of apertus and university stuff

Bertl_oO: true

However a great thing I found about windows is the integrated Linux shell

Very great

still not used to that ubuntu shell, using virtualbox mostly for apertus

Docker?

MCU -> microcontroller unit, microprocessor, like atmega or broadcom like raspi

to provide enough power for many clients

and i've thought that you have used punch cards and just recently discovered VIM ;)

that was 45 years ago :)

okay, 40 years ago :)

exposure to daylight is dangerous, you know ...

you've said something about orders from clients

any special area?

i mean are of industry, e.g. i'm working for a company, which is planning, building and developing software for automatic warehouses

ah, no, I usually look for customers with interesting projects

freelancer?

just wondering what else people are doing for living, besides regular office job

office job does not mean, that one only sits there, have to go to the new warehouse this year in another country

Wow

no, it's just short term, for some weeks

European Union?

i was asking for income as: apertus is related to camera and that camera sells right?

if you mean me, yes, in germany

Okk :)

Do you find work life as an informatics is stable?

Think*

TofuLynx, a job as software developer has many sides, sometimes i like it a lot, but on other days it's just tedious, but overall i can do the stuff i'm imagining in my free time, liek apertus

:D

in a company you have to follow the rules, but if you know your stuff you can shape the rules

TofuLynx, it depends on what you want to achieve

<Bertl_oO: I think it is better if some other set of eyes can look at your code... it is better for you too... and others as well>

(for a number of reasons)

(for a number of reasons) - can you list a few?

was just wondering when Bertl_oO said about another pair of eyes

I would pass using the cpp the DNG files and read that back..

otherwise you have to learn how to use CMake and so on

can you tell me how to do that... because then everything breaks

usually you don't have to modify them, just link to the shared lib, OCcore.so if i remember correctly and point the path to occore folder, have not extracted an API currently

like it is unable to find "OCcore_export.h" after this..

the process is aligned for CMake, but i will try to help you in the next days, as far as i have time, said already that i'm packing boxes for my move to new city soon

look for -> Compile main program and link with shared object library:

there should be seome info

hm... am i the only one not seeing messages by supragya ?

my hexchat is in sync to irc logs, so must be your client

all of them 😂

check with /ignore

good night, see you

i've meant, that my hexchat output is same as the one at irc.apertus.org

Ah okk

alright, LinuxMint logs for failing QEMU scripts posted, hope Medicine will take care of it or tell us how to fix

off to bed for me

there are 14 bits sensors?

wow

KAC12040

awesome

BAndiT1983, i am looking now at openCine source code

me too, want to move old stuff to archive, before deleting it finally at some point

in the image folder

seems incomplete

not sure, what does _ do in the start of variables?

i mark private variables like that, so i know that they shouldn't be accessible from outside the class

it's your technic

have started coding guidelines some time ago, have to make them more prominent

what is this?

sorry, double post, but there i've tried to gather some of them, not many at the moment

yep

it's empty

so the static analyzers don't complain

ah ok

what's that?

dynamic analyzers which look through the code by running it can cost several ten thousands of euros

just installed it

but there also free ones, this comes with some disadvantages though, as one has to go through a lot of output in console to find right info

you created a class called OCImage

was meant for general stuf of an image

it's not empty

but seems fairly complete

No problem :p

you can activate a plugin in qtcreator to show them in a separate window

well about that

I have never used the IDE before

don't know what can be used instead

also I think the OCImage class won't suffer major alterations, just minor ones

this kind of stuff

this is something i've talked about earlier today

also

what's an enum class?

hmm

hm, the guy is working at dropbox it seems, never knew that, although that article is known to me for years

no problem, it helped me a lot when started learning c++11 back then

Ok, so

yes

right?

.h and .cpp

yeah

as main file, otherwise had problems to build

all the modules were added long time ago, so there is a lot of stuff which has to be reviewed, removed and refactored

OpenCine

right?

hmm

wait

34

Okk :)

ah xD

What's OCui?

OCui is unified place for OC UIs, it provides same look and feel for all apps, like theme, application frame and so on

just look at OCBackup.cpp

application class is inherited from OCui::GUIApplication

makes sense!

is the most worked module

yes, focus shifted to backup solution, after numerous requests were made
