20130414 21:59:39 <sgothel> Good evening / morning
20130414 22:00:03 <sgothel> Dominik ? Still there ? I have a t-shirt question for siggraph 2013
20130414 22:00:33 <sgothel> i.e. I would like to buy ~50 t-shirts depending on costs .. w/ your logo
20130414 22:00:56 <sgothel> so we have give aways in our BOF .. and one for ourselves ofc
20130414 22:02:12 <sgothel> other than that - status: walking the bugs .. as you can see in git commits :)
20130414 22:03:50 <xranby_ac100> good evening, i am figting with a movie decoder (i guess).. the seek function in the FFMPEG media player is broken on my macine.. i get a divisin by zero due to pos1 2414, time_base.num 1 , time_base.den 90000 in Java_jogamp_opengl_util_av_impl_FFMPEGMediaPlayer_seek0
20130414 22:04:40 <xranby_ac100> thus 1000/90000 is about 0 in int64_t pts1 = (int64_t) pos1 / my_av_q2i32(1000, pAV->pVStream->time_base);
20130414 22:04:42 <sgothel> yeah .. seek didn't work well .. but I got no NaN error yet
20130414 22:05:07 <sgothel> oh .. if you can add a safe value .. your patch is ofc welcome!
20130414 22:06:15 <sgothel> but that should work, i.e. my_av_q2i32(1000, pAV->pVStream->time_base)
20130414 22:06:38 <xranby_ac100> my_av_q2i32(1000, pAV->pVStream->time_base) returns 0 on my machine
20130414 22:06:41 <sgothel> if not - the whole ffmpeg stuff would be broken, since they all operate on this timebase similar ..
20130414 22:06:47 <sgothel> that is weird
20130414 22:06:56 <xranby_ac100> time_base.num 1 , time_base.den 90000
20130414 22:06:58 <sgothel> time base 90000 ticks ..
20130414 22:07:07 <sgothel> yup
20130414 22:07:31 <sgothel> whats your machine ?
20130414 22:07:44 <xranby_ac100> the ac100 running ubuntu 12.10
20130414 22:08:05 <xranby_ac100> armhf
20130414 22:08:25 <sgothel> int32 calc should be correct .. hmm, no I need to check the methods again .. my_av_q2i32 .. etc
20130414 22:10:01 <xranby_ac100> static inline int32_t my_av_q2i32(int32_t snum, AVRational a){
20130414 22:10:02 <xranby_ac100> return (snum * a.num) / a.den;
20130414 22:10:02 <xranby_ac100> }
20130414 22:10:12 <sgothel> thx :)
20130414 22:11:49 <sgothel> int based .. would be always zero
20130414 22:11:59 <sgothel> hu ?
20130414 22:12:13 <xranby_ac100> yes.. and indeed i get a division by zero
20130414 22:12:24 <sgothel> so why not on other machines ?
20130414 22:12:41 <xranby_ac100> time_base.num 1 <---- i guess this is broken
20130414 22:13:29 <sgothel> stream timebase (DVD for example) is AFAIK always 1/90000
20130414 22:13:39 <sgothel> the magic ticks of mpeg stream
20130414 22:15:05 <sgothel> a: pos1 / ( ( 1000 * 1 ) / 90000 )
20130414 22:15:11 <sgothel> b: ( pos1 * 90000 ) / ( 1000 * 1)
20130414 22:15:16 <sgothel> a == b .. should help ?
20130414 22:16:03 <sgothel> i.e.: ( pos1 * time_base.den ) / ( 1000 * time_base.num )
20130414 22:16:06 <xranby_ac100> the big bucj bunny movie is ok time_base.num 1 , time_base.den 24
20130414 22:16:41 <sgothel> right .. and you play a DVD ?
20130414 22:16:55 <sgothel> mpeg / vob ..
20130414 22:17:03 <xranby_ac100> yup
20130414 22:17:20 <xranby_ac100> well i tested top layback one mpeg
20130414 22:17:39 <sgothel> so: ( pos1 * 24 ) / ( 1000 * 1 ) -> 0
20130414 22:17:58 <sgothel> for pos1 < ~400
20130414 22:18:15 * DemoscenePassiv (~Lutsche@anon) Quit (Ping timeout: 260 seconds)
20130414 22:18:22 <sgothel> err .. ~50 :)
20130414 22:19:27 <sgothel> guess that would help right ?
20130414 22:19:36 <sgothel> ( pos1 * time_base.den ) / ( 1000 * time_base.num )
20130414 22:19:50 <sgothel> pls test .. and commit, thx ..
20130414 22:19:54 <xranby_ac100> i will test
20130414 22:19:58 <sgothel> how about the t-shirt idea ?
20130414 22:20:04 <sgothel> Dominik just left .. :(
20130414 22:20:19 <sgothel> well, he created the artwork so far
20130414 22:20:23 <xranby_ac100> do us want baseball cap's with thick thread ?
20130414 22:20:56 <sgothel> hmm .. I am selfish, hence I thought of t-shirts :) .. me not wearing those caps
20130414 22:21:16 <xranby_ac100> if you want to have a logo with good quality then it might be a good idea to use thread instead of paint
20130414 22:21:38 <xranby_ac100> good that the logo is made up of 2 colors
20130414 22:21:54 <sgothel> 'thread' ? oh you mean actual stitching ?
20130414 22:21:59 <xranby_ac100> yes
20130414 22:22:14 <sgothel> holy moly .. we would have the best shirts on site then :)
20130414 22:22:56 <sgothel> good printed shirts .. might be around 20-30 USD, stitching ? I guess much more
20130414 22:24:31 <sgothel> guess I shall open a thread on forum .. hmm .. and invite Dominik in it as well
20130414 22:25:44 <xranby_ac100> stitched around 55 USD
20130414 22:26:41 <xranby_ac100> http://www.zazzle.se/logo+broderade+tr%C3%B6jor based on this data
20130414 22:31:13 <xranby_ac100> hmm got better price when browsing the US page http://www.zazzle.com/embroidered+shirts $34.9
20130414 22:32:16 <sgothel> small logo, more 'elegant' - nice idea
20130414 22:32:59 <sgothel> 1st I was more thinking in a 'jazz' direction, colors .. mosaic of logo, BOF history dates .. etc front and back :)
20130414 22:33:37 <sgothel> grrr .. can't find the link of Dominik's 1st edition of stuff .. some webpage, we did it years ago :(
20130414 22:34:10 <sgothel> http://www.cafepress.com/jogamp
20130414 22:34:37 <sgothel> why is this _not_ on our homepage ? :)
20130414 22:35:20 <[Mike]> There is also a teddy?!?!?!
20130414 22:35:27 <sgothel> hehe
20130414 22:35:54 * xranby_ac100 (~xranby@anon) Quit (Read error: Connection reset by peer)
20130414 22:45:30 <[Mike]> Aww man, what a perfect location for siggraph and I won't be able to go. Only 2 hour drive from my place.
20130414 22:46:27 <[Mike]> Well perfect as in distance from me. Never actually been to anaheim to say its 'perfect' for siggraph.
20130414 22:46:48 <sgothel> well .. it's a t-shirt :)
20130414 22:47:05 <sgothel> a fun thing, nothing big
20130414 22:47:38 <sgothel> but for some reasons, if 'they' can get free t-shirts, even the most educated folks get all crazy about it :)
20130414 22:48:10 <[Mike]> Hahaha, what people will do for free things.
20130414 22:48:29 <sgothel> .. some even asks questions for it :)
20130414 22:49:23 <sgothel> hmm .. hope the mpeg timebase term didn't fry Xerxes ac100 machine :)
20130414 22:49:30 <[Mike]> That's quite considerate of them
20130414 22:53:22 <[Mike]> 22d23h until poster submissions are due. Are you ready! :)
20130414 22:54:02 <sgothel> submitted for mobile session and our BOF, BOF accepted. I don't like those ancient poster, hey, we have a webpage :)
20130414 22:57:36 <[Mike]> True, QR codes? ...Or are they so 2012?
20130414 22:58:06 <sgothel> hu ?
20130414 22:58:11 <sgothel> which QRs ?
20130414 22:59:13 <[Mike]> The little barcode squares people put on advertisements so when people scan them with say a smart phone it will take them to a website or something.
20130414 23:00:41 <sgothel> oh right .. I sort of missed that one :) I am even too lazy to take my phone w/ me to check the ingredients of food w/ the bar-code :)
20130414 23:00:48 <sgothel> but .. nice idea though :)
20130414 23:01:19 <sgothel> if your URL is that complicated to memorize .. so you need QR .. well, something is wrong maybe ?
20130414 23:04:56 <[Mike]> True for the main website. Some embed the links to promotional videos or links that direct them to a product.
20130414 23:06:32 <[Mike]> I never really caught on, as you mentioned, too lazy to take out my phone, start an app that will read the code, and then take me to a website or something.
20130414 23:08:36 <[Mike]> On another note, we put them on our resumes to provide a link to our linkedin page (a university requirement).
20130414 23:09:42 <sgothel> oh, yeah, I put it in letters, well. sure, looks sort of fancy, even though it creates another tech-barrier
20130414 23:18:37 <[Mike]> That is a good point. How to break through that barrier? Become a cyborg?
20130414 23:18:50 <sgothel> buy google glass :)
20130414 23:19:02 <sgothel> err .. so yes :)
20130414 23:19:25 <[Mike]> That was going to be my first statement :P, but opted for something a little more far fetched :)
20130414 23:19:26 <sgothel> wonder when 1st fist fights break out in bars about it ..
20130414 23:19:51 <[Mike]> about google glass?
20130414 23:20:06 <[Mike]> or cyborg racism
20130414 23:20:10 <sgothel> sure .. I mean, heck, thats where you would want it .. :)
20130414 23:20:14 <sgothel> PRIVACY
20130414 23:22:25 <[Mike]> Ahh, privacy. Quite hard to obtain in these times.
