| 22:40 | jucar1 | hello
|
| 23:00 | jucar1 | he likes the project and asks me what is needed
|
| 23:16 | Bertl | hey jucar1! how's going?
|
| 23:17 | jucar1 | hello
|
| 23:18 | jucar1 | well I was talking to lu_zero a hw and sw hacker from torino gentoo and ffmpeg as I told you
|
| 23:18 | jucar1 | asking him for helping here
|
| 23:18 | jucar1 | he likes the project and he didn´t know about it
|
| 23:18 | jucar1 | he is in freenode now too
|
| 23:19 | jucar1 | I asked him to come but some time ago he told me he was going to sleep ...
|
| 23:19 | jucar1 | lets see
|
| 23:19 | lu_zero | joined the channel |
| 23:19 | lu_zero | hi
|
| 23:19 | Bertl | welcome lu_zero!
|
| 23:19 | jucar1 | opa luca
|
| 23:19 | jucar1 | wellcome and thanks
|
| 23:19 | lu_zero | jucar1: told me wonders about your project
|
| 23:19 | jucar1 | then bertl can tell you what is needed
|
| 23:19 | Bertl | jucar1 told me that you like it and want to help out
|
| 23:19 | jucar1 | lu_zero: we are very enthousiastic about it also with nik (3d man)
|
| 23:20 | jucar1 | Bertl: lu_zero was inside some other hw projects in media very interesting too
|
| 23:20 | jucar1 | and he was also developping some stuff for streaming for the turin politecnic , and specially lu_zero is an excellent person :)
|
| 23:21 | jucar1 | sorry my network still very bad today, with cell phone, tomorrow will be good, new connection at home
|
| 23:21 | lu_zero | ^^;
|
| 23:21 | Bertl | jucar1: not a psychopat like us?
|
| 23:21 | jucar1 | worst :)
|
| 23:22 | jucar1 | well lu_zero sove our lifes many times :)
|
| 23:22 | jucar1 | hacking
|
| 23:22 | lu_zero | I'm one of the people behind evil projects such as Libav or vlc (or Gentoo)
|
| 23:22 | Bertl | lu_zero: well, did you get an idea what apertus and axiom is about?
|
| 23:22 | jucar1 | aparently now he is half sleeping :)
|
| 23:22 | lu_zero | so take your guess ^^;
|
| 23:22 | lu_zer | is 3/4 asleep
|
| 23:22 | jucar1 | :)
|
| 23:23 | Bertl | we can postpone this till tomorrow, if you want to go to bed
|
| 23:23 | jucar1 | well the contact is done
|
| 23:23 | jucar1 | but I supouse lu_zero is chatting lots ...
|
| 23:24 | jucar1 | lu_zero: go ahed, we need people , I want to have a camera in january :)
|
| 23:24 | jucar1 | max february
|
| 23:25 | lu_zero | 4k ?
|
| 23:25 | lu_zero | Bertl: quick question
|
| 23:25 | lu_zero | who is in charge of the drivers?
|
| 23:25 | lu_zero | and how does it connect?
|
| 23:25 | Bertl | I'm currently working on the axiom prototype, so technical questions in my general direction, apertus and general axiom project related questions are better targeted at sebastian
|
| 23:26 | Bertl | we plan to use Linux on the Zynq as OS, so there will be drivers (to some extend) to access the video
|
| 23:26 | Bertl | I've started maintaining a kernel branch for this purpose, but it isn't set in stone yet
|
| 23:27 | Bertl | the heavy lifting (processing and buffering wise) will be done in the FPGA (PL part of the Zynq_
|
| 23:27 | Bertl | )
|
| 23:28 | Bertl | the PS (Linux) part mainly serves the setup and configuration purposes and 'some way' to capture frames or sequences
|
| 23:29 | Bertl | (if you do not understand what I'm talking about, please do not hesitate to ask :)
|
| 23:30 | jucar1 | I think lu_zero is reading the website ...
|
| 23:30 | lu_zero | I mean
|
| 23:30 | lu_zero | 4k
|
| 23:30 | lu_zero | either you encode it on fly
|
| 23:30 | lu_zero | or you need something able to push it to somewhere
|
| 23:31 | Bertl | nah, we do not want to encode it, at least not lossy encoding
|
| 23:31 | lu_zero | and it is a huge amount of data
|
| 23:31 | Bertl | and I know, really huge amount
|
| 23:31 | Bertl | for the prototype, the data path is like this:
|
| 23:31 | Bertl | 4k sensor data => PL (preprocessing) => 1080p => HDMI out
|
| 23:31 | jucar1 | excellent
|
| 23:32 | Bertl | for capturing 4k frames, I'm not worried about the data
|
| 23:32 | lu_zero | ah
|
| 23:32 | lu_zero | so basically
|
| 23:33 | Bertl | the final product (aka axiom) will feature several high speed serial ports
|
| 23:33 | lu_zero | you just put a scaler and then use the normal hdmi to validate the sensor
|
| 23:33 | Bertl | kind of, it's a little more complicated, but that's it basically
|
| 23:33 | lu_zero | I have some experience with genicam devices
|
| 23:34 | lu_zero | so I was curious about it
|
| 23:34 | Bertl | we need to do dead pixel removal, debayering and then rescaling
|
| 23:34 | lu_zero | debayering isn't a good idea =)
|
| 23:34 | Bertl | well, as the sensor uses bayer pattern, and hdmi is not :)
|
| 23:35 | Bertl | anyway, all this will happen in the FPGA on the fly
|
| 23:35 | lu_zero | then nobody cares beside who has to program it once ^^
|
| 23:35 | Bertl | the data will be buffered in DRAM, via the built in DMA controller
|
| 23:36 | lu_zero | sounds interesting
|
| 23:36 | Bertl | we might also do a proof of concept implementation of an overlay
|
| 23:36 | Bertl | which can be overlayed in the hdmi stream
|
| 23:37 | lu_zero | I can help probably mostly further down the road
|
| 23:37 | Bertl | yes, I figured from the ffmpeg reference
|
| 23:37 | lu_zero | (driver, capture integration, on-camera encoding and such)
|
| 23:38 | jucar1 | OT - lu_zero and in hw can you or do you know some good person ?
|
| 23:38 | jucar1 | (poli-people...)
|
| 23:41 | lu_zero | hw wise nobody
|
| 23:42 | jucar1 | ok, then I go for keltron
|
| 23:43 | jucar1 | I come back soon. go to kitchen
|
| 23:45 | lu_zer | goes to sleep
|
| 23:45 | lu_zero | let me know it/when you need me =)
|
| 23:47 | Bertl | have a good one!
