• [00:30:41] <robclark> any NEON/VFP folks awake?
  • [00:30:56] * mru is here
  • [00:31:21] <robclark> what exactly is an integer reciprocal? I mean, does VRECPE.U32 just give you an array of zero's?
  • [00:31:40] <robclark> (ie 1/n) if n != 1 => zero in integer
  • [00:32:28] <robclark> (basically, I'm trying to figure out how to scale numbers, ie multiple and divide, with integer result)
  • [00:32:49] <mru> you should really try to avoid the need to divide

  • [00:33:14] <robclark> I know.. but I need scaled random #'s... and the current code is horrible on ARM
  • [00:33:25] <robclark> gint64 tmp = gst_fast_random_uint32 ();
  • [00:33:25] <robclark> tmp = (tmp * (end - start)) / G_MAXUINT32 + start;
  • [00:33:39] <robclark> ends up being emulated..
  • [00:34:03] <robclark> but end and start are always the same..
  • [00:34:10] <robclark> so I was wondering if I could vectorize it..
  • [00:34:42] <mru> is G_MAXUINT32 not 0xffffffff?
  • [00:34:51] <robclark> nope, it's 0xffffffff
  • [00:35:09] <robclark> (I mean, yes it is)
  • [00:35:48] <mru> can't you use 1<<32 instead?
  • [00:35:52] <mru> it's only one more...
  • [00:36:02] <mru> and >>32 instead of /
  • [00:36:11] <robclark> yeah, that would make it a power of two.. but I'm not sure if the results will be right..
  • [00:36:23] <robclark> I guess I could try it when I'm in the office on monday, and see how it sounds
  • [00:36:23] <mru> who cares if random numbers are the same
  • [00:36:37] <mru> (a*b)>>32 is a single instruction
  • [00:36:43] <robclark> (this is for dithering, for converting audio samples from 32b float to 16b int
  • [00:37:35] * _gm_ (n=_gm_@190.173.94.75) has joined #beagle
  • [00:38:09] <robclark> well, I'll try that.. if it works, the rest of the conversion code should be easy to vectorize
  • [00:38:47] <mru> do you need really random numbers?
  • [00:38:56] <mru> or would looping over a table be good enough?
  • [00:39:21] <robclark> not sure.. I'm not really a signal processing guy
  • [00:39:40] <mru> dithering is an audiophile thing, not a signal processing thing
  • [00:40:04] <mru> you can't actually hear any difference
  • [00:40:07] <robclark> well, all I know is what wikipedia told me (http://en.wikipedia.org/wiki/Dithering)
  • [00:40:18] <robclark> I guess it needs to be psuedorandom
  • [00:40:34] <robclark> but I'm not sure how often it can repeat.. so I don't know about the table thing..

  • [13:14:25] <dual> I'm reading the beagle beginner page, and I've connected the board to my computer using an usb-miniusb. It says one led will light up immediately and two others will after a while
  • [13:14:40] <dual> It's been connected for a few minutes now, but still only one is lit
  • [13:14:58] <dual> One of them flashes on and of from time to time
  • [13:15:20] <adj> those two leds are software controlled
  • [13:15:32] <dual> Ok, so everything is fine then?

  • [14:51:51] <mithun4609> hello all...
  • [14:53:32] <mithun4609> any techie good in dsp????
  • [14:54:47] <Crofton|work> how good?
  • [14:56:00] <mithun4609> am doing a project in RF voice transmission... u like help me???
  • [14:56:44] <mru> why don't you buy walkie-talkie instead ;-)
  • [14:57:02] <mithun4609> guys am serious.....
  • [14:57:17] <mru> doesn't mean we are
  • [14:57:18] <mru> ;-)
  • [14:57:24] <mru> hey, it's sunday...
  • [14:57:37] <mithun4609> so...
  • [14:57:48] <mru> so I'm extra silly
  • [14:58:00] <ldesnogu_> which says a lot
  • [14:58:53] <mithun4609> mru wer u frm?? its interesting...
  • [14:59:20] * dirk2 (n=dirk@p5B041BC6.dip0.t-ipconnect.de) has joined #beagle
  • [15:01:03] <Crofton> what do you mean
  • [15:01:35] * mru didn't know silliness was confined to some particular geographic region
  • [15:02:01] <mithun4609> i am having an RF module working in TDMA
  • [15:02:21] <mithun4609> i would like interface it with beagle..
  • [15:02:27] <Crofton> what kind of rf module?
  • [15:02:53] <mithun4609> its freq in 2.4ghz tdma
  • [15:02:59] <mru> maybe you can use wires to connect it to the beagle
  • [15:03:12] <mru> jokes aside, what interface does it have?
  • [15:03:38] <mithun4609> ya its having usb interface thats not an issue..
  • [15:04:04] <Crofton> is there a web page for this device?
  • [15:04:09] <mithun4609> but the thing is beagle should act as a switching centre
  • [15:04:39] <Crofton> my crystal ball is out of focus .....
  • [15:04:45] <mithun4609> ya u can visit www.rfm.com and go to device DNT2400
  • [15:04:49] <Crofton> so you will need to describe the hw in detail
  • [15:05:12] <mithun4609> ya am ready...
  • [15:06:01] <mithun4609> the frame structure sending by the rf module is having 16 time slots..
  • [15:06:25] <Crofton> so basically you need a driver
  • [15:06:33] <Crofton> do they provide linux driver already?
  • [15:06:52] <mithun4609> no dont want driver
  • [15:06:58] <mru> wtf?
  • [15:07:55] <mithun4609> but beagle should have voice codec and should pick voice/data from user1 and direct it to user2
  • [15:08:33] <Crofton> the user guide says "Coming soon"
  • [15:09:25] <mithun4609> if the user1 calls user2, then rf will assign slot1 to user1 and assin slot2 to user2
  • [15:09:36] <Crofton> mithun4609, it looks interesting, but there is not enough docs to figure out how to proceed
  • [15:10:20] <mithun4609> beagle should pick the voice from slot1 and puts it to slot2. so user2 can hear wat user1 says..
  • [15:10:47] <mithun4609> u can get the documents of the device DNT900
  • [15:11:13] <mithun4609> there is only difference is that freq will be different..
  • [15:12:33] <Crofton> yeah
  • [15:12:43] <Crofton> basically, you need to work out how to do the interfacing
  • [15:12:55] <Crofton> you could buy an extra kit and send it to me!
  • [15:14:05] <mithun4609> not interfacing...
  • [15:14:35] <mithun4609> there is already usb interface...
  • [15:14:58] <ldesnogu_> which should magically make it work?
  • [15:15:19] <Crofton> you still need to write some code
  • [15:15:24] <Crofton> most likely using libusb
  • [15:15:29] <Crofton> well libusb1
  • [15:15:38] <mithun4609> ya definitly...
  • [15:15:51] <mithun4609> am not good in dsp...
  • [15:16:00] <mithun4609> am an RF engineer
  • [15:16:05] <Crofton> heh
  • [15:16:12] <Crofton> that is a normal problem
  • [15:16:25] <Crofton> you should be able to find some codecs
  • [15:16:41] <Crofton> also need to work out how the interfce works
  • [15:16:48] <Crofton> is it packet or stream based
  • [15:17:00] <mithun4609> wat should i do if i buy a beagle board..
  • [15:17:02] <Crofton> do they do any error detection/correction etc
  • [15:17:17] <Crofton> find someone that knows the software end
  • [15:17:32] <mithun4609> ya... CRC will be done on chip by RF module..
  • [15:18:06] <Crofton> so you could almost just feed samples from the mic to the rf board
  • [15:18:45] <mithun4609> ya. it can be done but it will encrypted on AES
  • [15:19:14] <Crofton> ok
  • [15:19:59] <mithun4609> would u plz guide me for this????
  • [15:20:16] <Crofton> I do not have enough information to do that
  • [15:20:29] <Crofton> and I do not think you have done enough research on the software
  • [15:20:39] <Crofton> basically, I would need the hw and have to do the design
  • [15:20:57] <Crofton> I do not mind answering questions, but I can't do the entire project for you
  • [15:21:00] <mithun4609> if this interface works.... it can act as a 3G tower at the cost of around $400
  • [15:21:24] <Crofton> well, I'm not sure about that
  • [15:21:46] * mru has seen software destined for 3g towers
  • [15:21:50] <mru> it wasn't pretty
  • [15:21:55] <mithun4609> ya it can acts as...
  • [15:22:20] <Crofton> can it handle multiple users, or is it designed for point to point links
  • [15:23:05] <mithun4609> no its point to multi point and multipoint to multipoint
  • [15:24:40] <mithun4609> buddy i think u understood wat should be done on beagle
  • [15:25:46] <mithun4609> mru u got any idea???
  • [15:26:13] <mru> you need to find out the interface to the module and obtain/write a driver
  • [15:27:19] <mithun4609> wat all software should be in my check list????
  • [15:31:17] <Crofton> dunno
  • [15:31:20] <Crofton> google
  • [15:32:06] <Crofton> we do not know
  • [15:32:20] <Crofton> we understand roughly what you are trying to do
  • [15:32:26] <mithun4609> ohhhh
  • [15:32:46] <mithun4609> thats good....
  • [15:32:47] <Crofton> basically, we would start googling and collecting information about possible sw packages that would hlpe sovle the problem
  • [15:33:18] <mithun4609> i have roaming around in google for 1 week...
  • [15:42:59] <djlewis> yep, chasing howto's on new products makes it an even better game :)

  • [17:48:53] <ldesnogu_> the name "para" sounds too much like parallel...
  • [17:49:13] <dual> ldesnogu, And that's no good?
  • [17:49:36] <ldesnogu_> I don't think it's good :)
  • [17:49:46] <mru> dual: is your computer less than 20 years old?
  • [17:49:55] <mru> if so, that's definitely the wrong cable
  • [17:49:56] <dual> mru, yes ;)
  • [17:50:11] <dual> mru: Ok
  • [17:50:16] <dual> I made my own cable too
  • [17:50:16] <mru> 25-pin serial ports are very rare these days
  • [17:50:39] <dual> I took a cable looking pretty much like this: http://amigakit.leamancomputing.com/catalog/images/30cm-ide-cable-44-pin.jpg
  • [17:50:48] <dual> Cut it so that it had 2x5 holes
  • [17:50:58] <dual> In both ends, and I've tried to connect it
  • [17:51:20] <dual> I've connected it to the COM slot on my motherboard, which has 9 pins, and to the beagle board
  • [17:51:36] <dual> 3 leds lights up, but would it work?
  • [17:51:43] <lemay> do you know what the pinout is supposed to be?
  • [17:51:55] <lemay> it's not necessarily stright through
  • [17:52:01] <dual> No, Just hoping for it to work.
  • [17:52:09] <ThomasEgi> dual, that wont work.
  • [17:52:13] <ldesnogu_> that looks dangerous
  • [17:52:22] <ThomasEgi> hope i mean. it's the desperate try to make things work by whishful thinking.
  • [17:52:22] <lemay> abort!
  • [17:52:33] <lemay> I *never* hope
  • [17:52:34] <mru> pins 2,3 on the beagle should connect to pins 3,2 on the pc
  • [17:52:38] <mru> pin 5 to pin 5
  • [17:52:51] <dual> Aha, ok
  • [17:53:20] <ThomasEgi> and if oyu dont know what pin are which number. they usualy are printed somewhere on the connectors. even if very small.
  • [17:53:57] <lemay> and once the cable is built, ring it out to make sure
  • [17:54:19] <dual> I don't have a serial port on my computer, do I need a serial to usb then?
  • [17:55:15] <djlewis> in a configure script id --with-gstreamer is selected is is supposed to block ffmpeg?
  • [17:55:22] <djlewis> id - is
  • [17:56:11] <dual> mru: is there a page that says what is pin should be connected to what pin?
  • [17:56:19] <djlewis> in a configure script with --with-gstreamer is selected is it supposed to block ffmpeg?
  • [17:56:31] <djlewis> better sentence :)
  • [17:56:56] <djlewis> do gstreamer and ffmepg coexist well ?
  • [17:57:03] <ThomasEgi> dual, mru just told you :)
  • [17:57:12] <dual> Is that the only differences?
  • [17:57:15] <mru> gstreamer doesn't really exist without ffmpeg
  • [17:57:20] <ldesnogu_> dual, if you don't have a serial port, then you'll have to either buy a serial card or a USB to serial cable
  • [17:57:26] <djlewis> thanks mru:
  • [17:57:43] <ThomasEgi> dual, you only need those 3 pins. leave the rest unconnected
  • [17:57:51] <dual> ldesnogu, I think I have a serial port card laying around somewhere
  • [17:58:14] <dual> ThomasEgi, Ok, then it doesn't sound that hard :)

  • [18:04:06] <koen> sounds suspiciously like gnash
  • [18:04:30] <djlewis> This is on BB local.

  • [18:05:42] <mru> gstreamer is just a silly wrapper around ffmpeg
  • [18:05:53] <javaJake> Or...
  • [18:06:03] <javaJake> gstreamer provides functionality for ffmpeg plus much more ;)
  • [18:06:21] <javaJake> (would rather ffmpeg, though; covers all the bases afaik)
  • [18:06:24] <djlewis> mru: so no real benefit to speeding up webcam or image decoding/encoding?
  • [18:06:27] <mru> true, it adds some bugs
  • [18:07:13] <javaJake> djlewis: try it with gstreamer and see if it's any better. Then go back to ffmpeg if it didn't speed it up any.
  • [18:08:00] <djlewis> javaJake: well, adds lots of time to project but its doable.
  • [18:08:17] <javaJake> djlewis: cp -R gnash gnash_with_ffmpeg
  • [18:08:27] <javaJake> djlewis: then recompile gnash/ with gstreamer
  • [18:08:32] <javaJake> djlewis: but keep your old ffmpeg copy

  • [18:10:35] <javaJake> OK
  • [18:11:04] <djlewis> thansk for the advice though. I'll note it for later.
  • [18:14:08] <djlewis> noted. I love copy/paste :)
  • [18:24:03] <djlewis> javaJake: I have already test a good deal with ffmpeg so this time I go gstreamer.
  • [18:26:55] <koen> when looking at gnash I always get the "their acid from the 60s must have kicked in while coding" feeling
  • [18:28:14] <djlewis> well, opencv is almost that old ;)
  • [18:28:53] <koen> I think xml usage is usually due to crack, not acid

  • [19:00:21] <ds2> at a high enough fps, the exposure time must go down
  • [19:02:09] <dual> Instead of using serial cables and null modems, can I make a cable like this? http://bildr.no/view/464800

  • [19:03:31] <dual> And if I'm right, I only need these 3 cables?

  • [19:04:42] <ds2> if you know what you are doing, you can just wire wrap 3 wires and be done with
