I'd like to work on Live histogram, waveform, vectorscope.
08:27
ams_
This project interests me. Since I work on computer vision problems and applications.
08:45
ams_
I tried compiling and running cmv_hist3
08:46
ams_
Its giving me "error mapping 0x60000000+0x00400000 @0x60000000." This error.

inside the AXIOM Beta camera
09:19
ams_
Okay
09:20
ams_
So how should I start contributing? Can you give me a direction?
09:21
davidak
Rex0r: to see what language is used in a repository you can click on the bar with multiple colors under "145 commits" https://github.com/apertus-open-source-cinema/opencine
09:21
davidak
that is a very nice designes and helpful feature :)
09:31
alexML
ams_: it's probably best to start with a PC implementation of those overlays, e.g. in plain C, so they don't require additional hardware
09:32
se6astian
Bertl_zZ: will be able to guide you on getting started on the FPGA side
09:32
se6astian
he should be online soon
09:34
alexML
you'll need some sample images in the internal representation used on the Beta; there are raw12 samples online, but the format is different than what you get from the image capture process, and for speed reasons, it's probably best to avoid conversions
09:35
alexML
they are easy to get; Herbert captured such images for researching the experimental raw recording via HDMI
09:38
alexML
(I wouldn't mind these indicators for raw2dng as well, though they probably belong to OpenCine)
09:40
alexML
(not sure if OpenCine already has them; they are present on the screenshot, but a quick search on the source code for histogram or waveform gives nothing interesting - BAndiT1983|away ? )

I did find the raw files on Beta.
09:48
ams_
alexML: As for the code implementation in plain C. Is it available somewhere?
09:50
alexML
ams_: you already have a Beta?
09:52
alexML
for source codes of our existing tools, look at https://github.com/apertus-open-source-cinema/
09:53
alexML
the overlays you asked about are already implemented in various open source projects (they are pretty well known)
09:57
ams_
alexML: I meant this : https://github.com/apertus-open-source-cinema/beta-software/tree/master/beta-images

BAndiT1983
which one? old screenshot, so i've almost forgot about it :)
18:51
d0
found it in the wiki
18:51
d0
the switch between Manage Process and Export on top rioght
18:51
d0
IMHO a split between OCBackup and the rest makes sense
18:51
BAndiT1983
ah, this thing, this was the first idea, to use almost the same principle like darktable and rawtherapee
18:52
d0
a split between Manage and Process not so much
18:52
BAndiT1983
some people told me that it would be better
18:52
d0
Well dunno
18:52
d0
Davinci Resolve also works like this
18:52

18:52
BAndiT1983
we can think about it, you have the experience in film making, i have experience in software development
18:52
d0
From a practical standpoint
18:53
BAndiT1983
there was also a request for btach processing through scripts
18:53
BAndiT1983
*batch
18:53
d0
it makes sense to make OCBackup its own thing
18:53
d0
lightweight, efficient, fast, reliable. Something you could even carry with you on some thumbdrive without pain
18:54
d0
Should do what it has to do and that pretty well
18:54
BAndiT1983
i thought about another thing -> backup on android ;)
18:54
BAndiT1983
haven't tried how qt behaves on android, but it would be interesting
18:54
d0
interesting how did you imagine it?
18:54
BAndiT1983
my smartphone allows to connect card reader through otg-cable
18:55
d0
aha well if it doesn't cost too much nerves..?
18:55
BAndiT1983
i'm doing backup of my dslr sometimes in that way, as the phone has total of 64GB
18:55
d0
for professional use it might not be that usefull
18:55
BAndiT1983
just saying, that we are not limited to windows or linux
18:55
d0
what would be useful though would be to have some remote status checking capabilites
18:56
d0
so if you copy you can check via network
18:56
BAndiT1983
good idea, if you don't mind, could you create a task in Lab, so we don#t loose the ideas?
18:56
d0
maybe you could even display remaining time on the camera
18:56
d0
I will note it down
18:57
d0
because Axiom can do networking â why not using it inside OCBackup
18:57
BAndiT1983
there are many possibilities, my focus is lightweight and speed
18:57
d0
I am with you : )
18:58
BAndiT1983
i've asked Sebastian about special features, but it was long ago, now i have a little bit more understanding of camera internals, so it should be possible
18:58
d0
shall I put this task under user wishes?
18:58
BAndiT1983
currently i'm occupied with fixing the build process, documentation in wiki and repository adjustments
18:58
d0
design?
18:59
d0
I see, I will try to collect everything
18:59
BAndiT1983
take a section, don't know which one, would usually say, that you can create a new one, but we have already too many of them
19:00
d0
I will put it in https://lab.apertus.org/T449
19:00
BAndiT1983
maybe under plugins, would be nice to add this feature in that way
19:00
d0
there seems to be a lot already
19:00
d0
maybe I should do some cleanup
19:00
BAndiT1983
T449 is rather specific and such task would be lost in there, so Plugins should be fine
19:01
BAndiT1983
if you believe you can, feel free
19:01
d0
cool
19:01
BAndiT1983
everything in there is open, i'm not hiding anything related to the project from people
19:02
d0
Did not get the feeling : )
19:02
BAndiT1983
jsut saying, as Sebastian asked often enough, if it is ok to share screenshots or infos on OC :D
19:03
BAndiT1983
and everytime i'm repeating that it is open source, so no restrictions from my side
19:10
d0
I like the spirit.
19:15
BAndiT1983
nice one, finally somebody who is actively creating tasks for OC
19:15
d0
haha, I just cand stand when ideas get lost
19:15
d0
when they get lost, it should happen on purpose, kill your darlings and all
19:15
BAndiT1983
all the tasks should be reviewed soon and sorted, as some things are already obsolete
19:16
d0
I am trying to get a overview, but I fear the wiki entry is also a bit stale already
19:16
BAndiT1983
some of them were transferred from github, but the last ones should also be
19:16
BAndiT1983
i'm on it, but i cannot proceed if the build process is not working to my liking
19:17
d0
sure
19:17
BAndiT1983
i've began to add build instructions, and while i'm on it the wiki will be adjusted, maybe you cann also take a look then, to read over and tell what's missing
19:18
d0
sure
19:19
d0
About Batching. One really needs to give it a thought. I think this would require deep integration into everything else, if it should be done in a way that Blender does it (everything scriptable via python)
19:19
BAndiT1983
if done correctly, then it shouldn't be too invasive
19:19
BAndiT1983
*invasive
19:20
d0
exactly, but it is not something that you can just add in the end
19:21
d0
I will brainstorm a little how this could look
19:21
BAndiT1983
no, not then, this should be done relatively soon, but i have no idea what to use it for
19:21
BAndiT1983
this is great
19:22
d0
I think there should be multiple ways. In blender you can call scripts from blender directly or start blender via shell with arguments and script and let it run in background
19:22
d0
both could have it's use
19:23
BAndiT1983
this is fine for processing, have to think of something for backup
19:23
BAndiT1983
by the way, how is you rendering progressing? already done?
19:23
BAndiT1983
*your
19:24
d0
Yes the next one is already starting, was in editing the whole day
19:24
d0
I am doing ten things at once
19:24
BAndiT1983
me too :D
19:24
d0
now that the daily is rendering I am working for open source stuff
19:25
BAndiT1983
tried my new FPGA programmer a bit and now OC development, tomorrow i should post-process the film further
19:25
BAndiT1983
do you use network rendering of blender?
19:25
d0
Also modular PCBs I designed arrived from china today
19:25

changed nick to: ams_
19:26
d0
I did too, for half my life, now my hunger for modular stuff won
19:27
BAndiT1983
i know that feeling, wanted to build some effects for my guitar before, but currently you see yourself :D
19:27
BAndiT1983
for example treble booster, to ressemble brian may one
19:31
d0
ah pretty basic circuit : ) well this is all about having the tools, the parts and a free evening
19:31
d0
Did a black magic camera repair the other time, their boards look really not that good
19:32
d0
soldering was bad, that was why the camera wouldn't charge anymore
19:32
BAndiT1983
overburdened or bulky routing?
19:32
BAndiT1983
ah, i see, quality issues
19:32
d0
not enough solder applied
19:32
d0
all over the board basically
19:32
d0
also a way to make more money on customers : D
19:32
BAndiT1983
china quality is varying, otherwise they produce great stuff
19:33
d0
as seen in my PCBs
19:33
d0
there is really nothing to complain
19:34
BAndiT1983
my package from bremen was okay, enclosure of the beepr is broken, but it works, is just an evaluation board and the programmer was more important to me
19:34
d0
where are you residing?
19:35
d0
or living
19:35
BAndiT1983
germany, near aschaffenburg
19:35
BAndiT1983
and you?
19:35
d0
ah, I am in Hamburg
19:35
BAndiT1983
lived there in 2010, while writing diploma at blohm+voss, fun time with cryengine3
19:35
d0
(I am Austrian though)
19:36
d0
did you like it?
19:36
BAndiT1983
no problem, i can live with that :D
19:36
d0
(jsut to warn you)
19:36
BAndiT1983
yes, it was ok, but i was almost alone there
19:36
BAndiT1983
hasn't mattered much as i've traveled often home and to my then girlfirend in würzburg
19:37
BAndiT1983
i have a colleague who is also austrian, is a foreigner according to papers :D
19:38
BAndiT1983
somehow it's funny, same language, history is also not far apart, but then this
19:38
d0
yeah the one thing where you feel it the most is actually when you go to the doctor
19:39
d0
foreigner means more paperwork, so they don't like you that much : )
19:40
BAndiT1983
really that bad? you are still have your austrian papers?
19:41
BAndiT1983
*-are
19:42
d0
not that bad, but the doctor situation in Hamburg is generally a bit odd. To much patients for too little doctors. If you are not an emergency you need to make dates two months in advance and such
19:43
BAndiT1983
i know a similar thing, got a cold while being in hamburg, had to search for a doctor
19:55
d0
do you have a plan how OCprocess would/could look like?
19:55
d0
a node based system? Or something with layers?
19:55
BAndiT1983
look at apertus site :D there is a mock-up which lead me to apertus back then in 2013
19:56
d0
sorry must have missed it
19:56
BAndiT1983
i think a simple node system, OC is not meant as full-blown editor, at least for now
19:56
BAndiT1983
no problem
19:56
intracube

19:56

https://www.apertus.org/opencine
19:56
d0
ahh below
19:56
d0
cool
19:56
BAndiT1983
nodes are my favorite, i played with node synths before
19:57
BAndiT1983
you see some resemblance in my screenshots
19:57
BAndiT1983
your task will be stylesheet adjustment, if you want
19:57
BAndiT1983
you also seem to like to play around with graphics, like me
19:58
d0
well actually I worked as Graphic Designer quite some time and learned typography with at some old guy who still learned how to do the metal typesets
19:58
d0
but I really like to tweak stuff like that yeah
19:59
d0
but can also be quite annoying at times. Depends how much the customer thinks he can do himself
19:59
BAndiT1983
i'm working with web development at work every day, but our UI is done by Google Web Toolkit (GWT), so i mainly write Java code, but sometimes i have to adjust CSS also
20:00
BAndiT1983
my mother complains about customers, when they send PDF files and all the layers for printing are misplaced
20:00
BAndiT1983
she is doing cup designs in a company which mainly does it for bigger companies in large amount
20:01
d0
haha
20:01
d0
well I do a lot of CSS too
20:02
d0
wrote something to process fountain files (a markdown-like screenplay format) into nice looking pdfs. Wasn't that easy to get it to behave
20:03
BAndiT1983
i'm still a little bit afraid of the work on PDF summary list of drive transfers
20:04
BAndiT1983
maybe i can prepare something in jasper reports, but it's java mainly
20:05
d0
I did a roundtrip via HTML but I worked with python
20:05
BAndiT1983
or maybe Qt allows to use HTML template
20:06
BAndiT1983
hm, maybe i can generate HTML and export to PDF afterwards
20:06
BAndiT1983
XML/XSD/XSLT, there are so many possibilities....
20:07
d0
well no need to tear one's leg, I would go for something fast easy with not too many dependencies
20:08
d0
any idea what kind of scripting language you would use there?
20:08
BAndiT1983
yes, that's also my point, but still evaluation of possible ways has to be done when we need
20:08
d0
exactly
20:08
BAndiT1983
don't know, python, lua?
20:08
d0
those are the typical ones
20:08
BAndiT1983
i have to follow the herd sometime :)
20:08
d0
if we wanna have good ties to blender maybe python would be smart
20:09
d0
so people who work on films, already do python stuff in blender can easily expand our apps here if they want to
20:10
BAndiT1983
good idea, maybe we can provide specific stuff from OC to blender for post-processing or something like that
20:11
BAndiT1983
it's possible that cameras could capture depth of the scene, then it would be interesting to insert objects in blender, without tracking
20:11
BAndiT1983
but it's all future music at the moment
20:11
d0
maybe even a blender integration? Blender has a lot over very might compositing tricks up its sleeve. If you could just say click a button and the selected clip loads in blender already placed into a compositor, that would be a dream
20:11
d0
and I know it is actually not that hard to do
20:12
d0
(even for 2D stuff only)
20:12
BAndiT1983
would be a good test for some special formats, like CDNG
20:13
d0
well I think we jsut need a node
20:13
d0
for blender
20:14
d0
like do whitebalance feed clip to a specific blender file, add some 2D compositing, write it back and work on with it or sth like that
20:14
BAndiT1983
hm, nice, ocprocess as node
20:14
d0
well I am coming from modular synthesizers â here even the master clock is jsut another node
20:14
d0
: D
20:15
BAndiT1983
have you seen dream theater performing pink floyd?
20:16
d0
I think this was the time I was in Iceland
20:17
BAndiT1983
there is a scene where the keyboarder is plugging cables into old synths
20:17
BAndiT1983
don't remember which song, although i know them rather good

nice one, d0, have always wondered about blender pipeline, was about film projects and i wanted to include substance designer or painter
20:45
d0
Honestly the only thing that is still annoying to do with blender is editing and fast paced compositing

but I find myself animating titles and other stuff in blender. Not because it is Open Source, but because it is great for certain animations
20:47
BAndiT1983
i know :D the old UI was awful, in my opinion, as 2.5 appeared it improved a lot
20:48
BAndiT1983
tried keying with it and was very surprised how good it works
20:49
d0
I actually entered with 2.5 and skipped using Blender Internal directly
20:49
d0
but I fell in love with the GUI
20:49
d0
it is nicely modular
20:50
d0
you can do everything you want, and at the same time hide all the 10.000 things not needed at the moment

i had to use blender internal, 2012 i joined the film group and required smoke and flame, but it was in GSoC development then, so i've installed ubuntu and built blender from specific branch every day anew
20:50
BAndiT1983
cycles hasn't supported smoke and fire for long time
20:53
d0
this was the only exception I made for BI : )
20:53

i've seen that some guys who had interest in OC where involed in latest blender version, if i'm correct that it was the latest
20:54
BAndiT1983
one has done 2d stabilizaton stuff, another one done filmic color options
21:01
d0
ah the filmic blender guy? Would really be an asset
21:03
BAndiT1983

here to get the idea of people which came by in the last years -> http://www.imdb.com/name/nm2794624/
21:04
BAndiT1983
oha, he is also Libra :)
21:07
BAndiT1983
and the guy from this project -> http://www.imdb.com/name/nm2794624/ , has done 2d stabilization for blender
21:07
BAndiT1983

using filmic blender a while now yeah
21:08
d0
much better color behaviour
21:08
BAndiT1983
troy told me about splitting OC first
21:09
BAndiT1983
haven't used it yet, as i had more post processing in AE todo, latest blender render session was in december to get some dragon fire to fry some bandits
21:10
d0
mhhh
21:11
d0
you know I am not to sure. Splitting is good in big productions, but for smaller stuff it is impossible to predict waht will be needed at a time
21:11
d0
for example if you have a data wrangler he/she might wanna "manage" the metadata before doing the backup
21:11
BAndiT1983
splitting the apps is not a big deal, they will interprocess of course, if required
21:12
BAndiT1983
modular ;)
21:12
d0
exactly : )
