hi good evening folks
04:47
gits
want to ask about GSOC2018, C++ qualifying tasks
04:47
gits
do I still have sometime to do them?
04:47
gits
I see some dates in GSOC2018 website
04:47
gits
I hope i can still do it before 27 right?

Hey, BAndiT1983 , can you review my C++ challenge code?
16:57
TofuLynx_
I mean, when you are available.
16:57
supragya
Hi TofuLynx_
16:58
supragya
have you registered yourself at summerofcode.withgoogle.com?
17:02
TofuLynx_
Hey Raj!
17:02
TofuLynx_
not yet
17:02
TofuLynx_
going to do it right now :)

BAndiT1983
supragya, what is the latest state with AVI provider?
20:04
supragya
state as in?
20:04
BAndiT1983
have you solved color problem?
20:04
supragya
not really
20:04
supragya
would still have to look it up
20:04
BAndiT1983
native ubuntu video player was still giving errors, but VLC shown a gradient from pink in the top to green in the bottom
20:05
supragya
yes... that is the error
20:05
supragya
IDK why that is happening
20:05
BAndiT1983
i will check your proposal now and afterwards play a bit around with re-structuring, have still some tasks for apertus on my list which are not done
20:05
supragya
sure.. have a look
20:05
BAndiT1983
how is the frame data embedded?
20:06
supragya
well it is not embedded as of now
20:06
supragya
but if you look in the main function
20:06
BAndiT1983
what is VLC showing?
20:06
supragya
VLC is showing a synthetic image
20:06
supragya
you can have a look at the frame data
20:07
supragya
from avi_create,cpp or something of the driver file
20:07
supragya
used in the project
20:07
BAndiT1983
is it RGBRGBRGB...?
20:07
supragya
yes
20:07
supragya
it should be white and shades of grey
20:08
supragya
The frame logic in you PM

BAndiT1983, can we discuss here?
20:30
LordVan

20:35
BAndiT1983
yes
20:36
supragya
did you infer something from the link you gave me?
20:37
supragya
how does MEDIASUBTYPE_RGB24 show itself in FOURCC?
20:38
BAndiT1983
still checking it, but also looking a bit at the mentor guide for gsoc about your scope question
20:38
supragya
scope question?
20:39
BAndiT1983
about goals and how they can be extended
20:39
BAndiT1983
the scope of the gsoc in general
20:39
supragya
here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd407212(v=vs.85).aspx . Seems like top-down DIBs had errors too
20:39
supragya
okay sure
20:40
BAndiT1983
the direction is also important, but we should fix the compression problem first
20:40
BAndiT1983
if you use RGB2, then the red channel is not there
20:40
supragya
I guess top-down DIB error can be corrected if DWORD is set to int32_t not uint32_t
20:40
BAndiT1983
try to extract 1 frame with VLC and check the content
20:41
supragya
the lower stripes have shade of red
20:41
BAndiT1983
seen it just now
20:42
BAndiT1983
Codec: 8 bits RGB (RGB2)
20:42
BAndiT1983
this is the info about your file
20:43
BAndiT1983
check the values here maybe -> https://github.com/usnationalarchives/AVI-MetaEdit/blob/master/Source/MediaInfoDLL/CodecIDs.h

supragya, orientation is top-left, according to VLC info
20:50
supragya
strange
20:50
supragya
it was bottom up DIB
20:50
TofuLynx
BAndiT1983, I will share the draft proposal on GSoC's platform
20:51
supragya
see L126
20:51
BAndiT1983
TofuLynx, alright
20:51
supragya
success BAndiT1983
20:51
supragya
we got it
20:51
BAndiT1983
?
20:52
supragya
the codec is 0x00000000
20:52
BAndiT1983
:D
20:52
supragya
or SF.biCompression.byte[0] = SF.biCompression.byte[1] = SF.biCompression.byte[2] = SF.biCompression.byte[3] = 0;
20:52
supragya
affects L131
20:52
supragya
try it on your end
20:52
supragya
you may want to affect L100 too
20:52
supragya
SH.fccHandler.byte[0] = SH.fccHandler.byte[1] = SH.fccHandler.byte[2] = SH.fccHandler.byte[3] = 0;
20:53
supragya
BAndiT1983, tell me if gradient is okay on yor end
20:53
BAndiT1983
there is a bit nicer solutions for that, but for the moment it's ok
20:53
supragya
and it is bottom up DIB for sure
20:53
BAndiT1983
will compile in a moment
20:53
supragya
works for now! will refactor later
20:54
BAndiT1983
VLC still refuses to load, if i change both
20:55
supragya
let me commit my changes
20:55
supragya
what works on my end
20:56
supragya
done, you may now git pull
20:56
BAndiT1983
ok
20:57
supragya
use create.sh
20:57
TofuLynx
BAndiT1983 , shared. I would be glad if you reviewed it when you have time :)
20:58
BAndiT1983
supragya, works here too
20:58
supragya
:)
20:58
supragya
finally...
20:58
BAndiT1983
TofuLynx, will try to do it, if the access is there
20:59
TofuLynx
Thanks!
20:59
supragya
BAndiT1983, so all systems are in place... just need to be coupled
20:59
BAndiT1983
yes, and big refactoring required
20:59
supragya
and refactored ofc
20:59
BAndiT1983
TofuLynx, i don't have acces to gsoc yet, se6astian has to invite mentors etc.
20:59
BAndiT1983
*access
20:59
supragya
thanks for help tonight
20:59
BAndiT1983
you have done it, not me
20:59
TofuLynx
Roger! I can send via PM the share link if you want
21:00
BAndiT1983
google docs maybe?
21:00
TofuLynx
yeah it's on google docs
21:00
BAndiT1983
ok
21:01
supragya
BAndiT1983, I really don't know the extent of things I should write. I will ask your feedback maybe tomorrow, when I complete most of it
21:02
supragya
if you are still going through the doc, put some comments and I will check!
21:02
se6astian
BAndiT1983: ah thanks for the reminder
21:02
BAndiT1983
will try to get some time tomorrow, but not for sure, as many things like water system installations and electrical stuff have to be done in the new apartment
21:03
supragya
so much for new apartment. :)
21:03
se6astian
done
21:04
supragya
se6astian, much of my proposal is not done... however 60% of it is complete. Should I share the draft?
21:04
BAndiT1983
used to do this things myself, it's like Lego for big children ;)
21:04
supragya
using the website?
21:04
supragya
just a few more years for me... then these would be my problems too
21:05
TofuLynx
same supragya
21:05
TofuLynx
would love to build the furniture in my new house though
21:05
supragya
easier said than done
21:05
TofuLynx
I have a hobby with woodworking
21:05
TofuLynx
and I love it :P
21:06
seku
mh... random question thrown in: are we going to see an E-mount socket on the beta?
21:06
supragya
BTW, a large one off my shoulder... the AVIEncode finally works... so off for now
21:06
BAndiT1983
no space for such stuff here, but i have at least a table where i can solder and so on
21:06
seku
(as e-mount can accept speedboosters :)
21:06
BAndiT1983
https://lab.apertus.org/search/query/cG2BZKl_J7K8/#R
21:07
seku
thanks for the quick answer :)
21:08
BAndiT1983
hope it helps, i don't have much insight into available things
21:08
seku
(i'd love to combine an e-mount speedboosters with some of my anamorphics ... wonder how big i can go)
21:08
se6astian
supragya: se6astian, much of my proposal is not done... however 60% of it is complete. Should I share the draft? <- hard to say, do you think its ready for feedback?
21:08
supragya
I guess I should take a bit more time
21:08
se6astian
seku: mh... random question thrown in: are we going to see an E-mount socket on the beta? <- uhm, the Beta has only an emount currently
21:09
seku
se6astian: my bad. i should keep up more
21:10
supragya
good night everyone!
21:10
TofuLynx
Good night!
21:10
supragya

21:11
seku
seeing as i already asked stupid questions : how about cineform RAW? waiting for the ffdshow implementation i gather?
21:12
seku
just being curious :)
21:12
se6astian
the beta currently cannot write footage internally
21:13
BAndiT1983
is ffdshow still alive?
21:13
se6astian
the plan is to transfer raw data over usb3 and then store it as uncompressed raw
21:13
se6astian
cineform compression would need to happen on the FPGA in realtime -> big challenge so probably not something for the near future
21:14
seku
of course
21:14
se6astian
even though now that cineform has been open sourced it would definitely be technically possible
21:14
se6astian
if the logic fits into the FPGA which would still need to be evaluated
21:14
seku
last time i checked in, there was some talk about multiple SDI to get the data off the beta
21:14
se6astian
correct
21:14
se6astian
that development is currently ongoing
21:14
se6astian
dual 6G SDI output
21:15
seku
great :) as USB3 seems quite a bit restrictive, bandwidth-wise
21:15
se6astian
we showed first prototypes of the hardware and a single 3G SDI stream at the CCC
21:16
seku
yeah, i read about those conferences, nice job!
21:16
se6astian
thanks
21:16
se6astian
off to bed now
21:16
se6astian
good night!
21:16
se6astian

21:16
seku
gut nacht :)
21:19
seku
(the reason i asked is manifold. we did some silly calculations about using the super35mm chip in opengate 4:3 RAW mode on the axiom. add a .71x speedbooster on that, and add an anamorphic lens. one should be able to "fake" the Alexa65 sensor size)
21:19
seku
which should be a quite fun experiment
21:23
seku
ah, well, just a fun thought experiment
21:23
BAndiT1983
TofuLynx, funny stuff if i google "tofulynx github", then your c++ challenge code appears as first result, they know too much about my habits
21:24
BAndiT1983
would discuss your code tomorrow in PM
