| 21:05 | BAndiT1983 | good luck with going through the process to use it, as you need the license from this guys -> http://www.mpegla.com/main/programs/AVC/Pages/AgreementExpress.aspx
|
| 21:07 | BAndiT1983 | at least there is no royalty under 100,000 units per year, but the license hassle could be bigger than necessary
|
| 21:07 | BAndiT1983 | isn't there some open alternative to that stuff?
|
| 21:11 | Kjetil | depends on what you need?
|
| 21:11 | Kjetil | you have the VP8-family of codecs
|
| 21:12 | Kjetil | Or VC-2/Dirac
|
| 21:12 | Bertl | there is HDL code for that?
|
| 21:13 | Kjetil | That is a different story :)
|
| 21:14 | BAndiT1983 | VP9 has HDL
|
| 21:15 | BAndiT1983 | but the question is more how to get hold of it, as it's not very clear at first glance
|
| 21:15 | BAndiT1983 | https://www.webmproject.org/hardware/vp9/
|
| 21:19 | BAndiT1983 | mithro, what about theora? some vhdl -> https://svn.xiph.org/trunk/theora-fpga/theora_hardware/
|
| 21:19 | Bertl | we should definitely inquire about the VP8 and VP9 HDL
|
| 21:21 | BAndiT1983 | Bertl, will you complete their form to get hold of it?
|
| 21:23 | BAndiT1983 | maybe this is the right link -> https://www.webmproject.org/license/
|
| 21:24 | BAndiT1983 | as their "form" link jumps to the "Hardware" page which is not very helpful besides getting overview
|
| 21:24 | Bertl | don't know ... haven't found the form yet :)
|
| 21:27 | BAndiT1983 | "The WebM Project develops video hardware IP designs to assist our partners wishing to deploy VPx technology. OEMs, please contact your Google partner representative for more information."
|
| 21:28 | BAndiT1983 | maybe you can set off an e-mail and see if they reply
|
| 21:32 | Bertl | RexOrCine and se6astian are good at this stuff ^^;
|
| 21:34 | BAndiT1983 | right :)
|
| 21:40 | BAndiT1983 | Bertl, how many changes does the sensor tolerate, will there be a problem if we set config buffers over and over at very short time, e.g. moving slider and setting gain, which include 5-6 different settings
|
| 21:40 | BAndiT1983 | it's about porting the script to Go and daemon part -> https://github.com/apertus-open-source-cinema/beta-software/blob/master/beta-scripts/set_gain.sh
|
| 21:41 | Bertl | the sensor doesn't really care, but usually you want to synchronize changes to the frame
|
| 21:42 | Bertl | (to avoid having mid-frame changes)
|
| 21:43 | BAndiT1983 | hm, how can this be accomplished? is there some way to implement it partially in HDL, so it pushes the things to the chip in sync?
|
| 21:43 | BAndiT1983 | we had some discussion about it before, but it was long time ago
|
| 21:43 | Bertl | I've thought about that, but it's rather tricky to handle
|
| 21:44 | Bertl | I think the best way to address this is with a frame interrupt
|
| 21:44 | BAndiT1983 | let's start with simple things, how could i do the sync from daemon? is the interrupt accessible in arch?
|
| 21:44 | Bertl | we don't have one yet but that would be easy to add
|
| 21:45 | Bertl | the interrupt could be used from a kernel driver or from bare metal
|
| 21:45 | Bertl | the simplest way to utilize it from Linux userspace is via the UIO driver
|
| 21:45 | Bertl | (which provides a blocking read interface)
|
| 21:47 | BAndiT1983 | currently approaching the state of things, where we could start to test the daemon etc. on the camera soon
|
| 21:47 | BAndiT1983 | just want to ensure beforehand, that we are taking the right way
|
| 21:48 | Bertl | we might later add a special kernel driver to take care of all the frame related details
|
| 21:49 | BAndiT1983 | alright
|
| 21:49 | Bertl | btw, I'm really curious to see the daemon in action :)
|
| 21:50 | Bertl | (i.e. looking forward to have it running on real hardware)
|
| 21:51 | BAndiT1983 | me too ;) very simple GUI with gain slider is there, now i will implement the Go part, afterwards i will just check the daemon, if it has all the necessary stuff for first tests, as the image sensor configuration waws implemented before gsoc
|
| 21:52 | BAndiT1983 | maybe se6astian can assit with moving stuf to right place on the camera, e.g. webpage to the webserver and so on
|
| 21:52 | BAndiT1983 | *assist
|
| 21:52 | BAndiT1983 | *stuff
|
| 21:52 | Bertl | I'm sure he can
|
| 21:59 | se6astian | sure :)
|
| 21:59 | se6astian | the default firmware has no webserver installed
|
| 21:59 | se6astian | but I created a guide: https://wiki.apertus.org/index.php/Installing_a_webserver_on_AXIOM_Beta
|
| 22:00 | BAndiT1983 | what's the progress of the build script, by the way?
|
| 22:00 | se6astian | none
|
| 22:00 | se6astian | at least not in the lab
|
| 22:00 | se6astian | https://lab.apertus.org/T737
|
| 22:01 | BAndiT1983 | not QEMU, the general one for the firmware, wasn't there another task for it and some discussion not long ago?
|
| 22:03 | se6astian | not that I am aware of
|
| 22:03 | se6astian | Bertl: you made some progress with firmware building IIRC?
|
| 22:04 | BAndiT1983 | https://lab.apertus.org/T697
|
| 22:05 | se6astian | we should revive that :)
|
| 22:06 | se6astian | but to do that with more energy I am going to sleep now :)
|
| 22:06 | se6astian | good night!

| 22:43 | RexOrCine | Here.
|
| 22:49 | RexOrCine | BAndiT1983 "Google, Matroska and the Xiph.Org Foundation make the various components of WebM openly available on royalty- free terms" Is there no alternative to working with Google?
|
| 22:50 | BAndiT1983 | Rex, don't ask me, i'm not a user, so i don't know precisely what the initial post about h264 was pointed at
|
| 23:06 | RexOrCine | Reading the terms. Is HDL Hardware Distribution License?
|
| 23:10 | RexOrCine | hardware description language right.
|
| 23:11 | BAndiT1983 | second one
|
| 23:11 | BAndiT1983 | i don't think that Bertl wants to do much with licenses on Zynq ;)
|
| 23:16 | RexOrCine | Is the intention to use VP8 HDL, just examine it, or to use it for the purposes of creating something different?
|
| 23:17 | RexOrCine | use it for ideas with the purpose*
|
| 23:19 | RexOrCine | Also, is the cross-license agreement something that's already been signed by timvideos for Numato Opsis?
|
| 23:22 | BAndiT1983 | maybe it was about encoding in hardware, don't really know, we have to ask mithro
|

| 00:42 | mithro | I was asking because it is an implementation of h264 and apparently works on FPGAs
