[01:19:47 CET] <kierank> Lavfi doesn't know what time is so it won't work in real-time
[12:14:18 CET] <gagandeep> kierank: i think i have fixed the other bug where the last 8 pixels were distorted in 1080 frame
[12:14:55 CET] <kierank> gagandeep: send a patch to the mailing list
[12:15:49 CET] <gagandeep> yeah, will do today only, let me see that i haven't broken anything else and it was because of the extra space allocated to height
[12:16:28 CET] <gagandeep> kierank: btw why were you doing the FFALIGN on height anyway, because of other formats?
[12:16:43 CET] <kierank> yes probably
[12:17:45 CET] <gagandeep> k, kierank: will send the patch today after some work and by sunday i want to fix that interlaced issue because after that i have some course work to catch up to in university
[12:17:54 CET] <kierank> ok
[13:09:47 CET] <jdarnley> If I declare "const Plane *p" where "Plane" is a struct, all members in the struct are considered "const", right?  That is why I am getting warning about discarding the const qualifier, right?
[13:11:56 CET] <jdarnley> I guess so.  Removing the const on the pointer declaration gets rid of the warning.
[13:16:47 CET] <nevcairiel> indeed
[13:17:31 CET] <nevcairiel> if you just want the pointer itself to be const you would have to write Plane * const p, but thats usually a bit unusual of a thing to do
[13:17:39 CET] <kyle> hey all guys
[13:17:59 CET] <kyle> im trying to parse EPG on my TS stream , somone on it? so we can coolaborate?
[13:18:53 CET] <jdarnley> I've not heard of anyone working on that in regards to ffmpeg.
[13:19:01 CET] <jdarnley> Dammit man!
[13:19:27 CET] <jdarnley> Are you the same kyle as a moment ago?
[13:19:40 CET] <jdarnley> I've not heard of anyone working on that in regards to ffmpeg.
[13:20:14 CET] <Kylehyde5> Yes im the same
[13:20:34 CET] <Kylehyde5> Im working on it, but i dont know if it will be possible so thought if somone working on same
[13:20:44 CET] <Kylehyde5> Anyway i appreciate your help a lot.
[13:20:45 CET] <jdarnley> It could have passed me by because I don't follow TS developments.
[13:21:40 CET] <nevcairiel> EPG probably wouldnt fit ffmpeg properly anyway, you could expose it as a data stream or something, but any handling/processing is probably outside of what fits into  our design
[13:25:58 CET] <Kylehyde5> So ffmpeg cant send epg info?
[13:26:41 CET] <Kylehyde5> Its not possible to program it ? on mpegtsenc.c ? Im asking because im trying to devel it and i thought is the same possible as programming it on Python (Opencaster) is
[13:31:23 CET] <jdarnley> ffmpeg could demux and send it as a data stream to a user program or a muxer.
[13:31:46 CET] <jdarnley> in theory
[13:32:35 CET] <jdarnley> But I haven't heard that it is yet capable of doing that.
[13:36:44 CET] <Kylehyde5> Not capable yet, but it wont be capable of doing that?
[13:36:49 CET] <Kylehyde5> so EPg has to be inserter on a muxer?
[13:36:53 CET] <Kylehyde5> inserted*
[15:48:54 CET] <bogdanc> @muken, what externals did you mean in bug 3776?
[16:00:35 CET] <muken> bogdanc: some means outside the decoder such as demuxer which tell it the current frame number
[16:02:39 CET] <bogdanc> would it be a good idea to save the currently working alsDecContext and make a getter function for the frame id?
[17:07:20 CET] <BBB> kierank: are you partying @ nab this year?
[17:07:29 CET] <kierank> yes
[17:07:57 CET] <durandal_1707> so anyone gonna try hrtfm filter, and report if horizontal spatialization works for him?
[17:10:43 CET] <jamrial> wm4: https://github.com/jamrial/FFmpeg/tree/buffer_pool_dyn
[17:12:07 CET] <jamrial> it seems to work, and reuses most of the existing API
[17:13:22 CET] <jamrial> michaelni's AVTreeNode api is pretty neat
[17:21:43 CET] <wm4> can look later
[17:29:49 CET] <kierank> BBB: are you
[17:32:19 CET] <BBB> thinking about it
[17:32:23 CET] <BBB> probably yes this time
[17:32:31 CET] <BBB> what days should I go?
[17:32:34 CET] <BBB> the website is terrible
[17:33:20 CET] <wm4> what's a nab
[17:34:03 CET] <BBB> wm4: its something that eats your wallet
[17:34:11 CET] <BBB> nabshow.com
[17:36:09 CET] <durandal_1707> better spent it on bitcoins seminars
[17:38:14 CET] <wm4> oh, commercial jacking off show
[17:57:03 CET] <BBB> wm4: I spose, yes
[17:58:52 CET] <kierank> BBB: monday-wed
[17:59:01 CET] <kierank> if I'd have known we'd have got a bigger airbnb
[17:59:04 CET] <kierank> going as one is expensive
[17:59:10 CET] <kierank> but adding more people is cheap
[17:59:37 CET] <durandal_1707> go into normal hotel, like a hipster
[17:59:56 CET] <BBB> ?
[18:00:01 CET] <BBB> what is so expensive?
[18:00:06 CET] <BBB> I checked hotels and flights and its not so bad
[18:00:11 CET] <BBB> are tickets expensive?
[18:01:36 CET] <kierank> hotels
[18:01:49 CET] <kierank> comparable with new york i guess
[18:02:46 CET] <durandal_1707> why pick cheap? when you can spend all your money!
[18:03:07 CET] <atomnuker> durandal_1707: its las vegas, never been there but I don't suppose there are any normal hotels
[18:03:08 CET] <BBB> you need money to go again next year, durandal_1707 
[18:08:34 CET] <durandal_1707> you work all next year for next nab show
[18:10:31 CET] <durandal_1707> atomnuker: LDAC decoder/encoder when?
[19:13:58 CET] <amanharitsh123> Hello Everyone , I am a experienced C programmer and also very familiar with git . I want to contribute to the Org this year under GSOC
[19:14:36 CET] <amanharitsh123> Can any mentor please suggest me a way to start with ? Thank You :)
[19:15:23 CET] <durandal_1707> pick project you want to work on and contact mentor.
[19:25:01 CET] <amanharitsh123> durandal_1707 : I am currently going through the list .I have some doubts like ,  Do the organization have some priority among the projects ? I would like to work on a project which would be more beneficial to the community 
[19:25:29 CET] <durandal_1707> there is no priority
[19:25:48 CET] <kierank> BBB: where are you staying
[19:25:59 CET] <durandal_1707> amanharitsh123: only already taken projects and not taken
[19:26:27 CET] <durandal_1707> kierank: at your place, as always
[19:27:37 CET] <BBB> dunno; wynn appeared to be nearby
[19:27:50 CET] <BBB> I havent planned yet :-p
[19:42:50 CET] <atomnuker> durandal_1707: what's LDAC?
[19:43:00 CET] <atomnuker> dac == digital audio tape?
[19:43:34 CET] <atomnuker> which reminds me, TD-Linux: what happened with opus on a casette tape?
[19:44:29 CET] <durandal_1707> atomnuker: hifi codec similar as aptx hd, but bigger bitrate and from sony, there is encoder lib under apache 2.0
[19:46:50 CET] <atomnuker> got a link to the lib?
[19:48:08 CET] <durandal_1707> atomnuker: https://android.googlesource.com/platform/external/libldac/+/master
[19:49:53 CET] <atomnuker> seems similar though simpler than atrac9
[19:50:37 CET] <durandal_1707> hah
[20:45:16 CET] <wm4> jamrial: seems reasonable, but would we need mechanisms to prevent what would be effectively memory leaks due to huge fragmentation?
[20:46:15 CET] <jamrial> wm4: something like a function to nuke the tree based pool without uninitializing the whole thing?
[20:49:29 CET] <jamrial> notice that it tries to replaces the currently bigest buffer in the pool if none of the needed size is available, with one that does meet the required size
[20:52:00 CET] <wm4> I guess there are many kinds of heuristics possible to deal with it somehow
[21:19:32 CET] <daddesio> atomnuker: if he finishes that project, next one should be av1 on a VHS tape
[21:36:07 CET] <kierank> durandal_1707: you are more than welcome to sleep at my place
