[00:11] <cone-85> ffmpeg.git 03Andrey Utkin 07master:8cc6e91f6950: Document smoothstreaming muxer
[00:51] <brimestone> hey guys... i'm getting frustrated with AVFoundation and wants to add ffmpeg into my Objective-C project, where shold i start.. any pointers?
[03:00] <jamrial> libav keeps postponing the native opus decoder because any fix or improvement seemingly needs to be squashed into the first big commit
[03:09] <iive> yes... it must be perfect on the first commit or the project would crash in flames.
[03:10] <iive> and all copyright assignments should be scrubbed clean, so nobody knows who changed what.
[03:12] <iive> It's not like (L)GPL requires proper copyright attribution.
[03:12] <iive> ~~
[03:32] <jamrial> I mean, i could see them wanting to do that with show stopping bugs, but to factor out code for performance reasons and remove an unused variable?
[03:33] <jamrial> v5 will probably not be posted until like monday, then the cycle will begin anew
[03:34] <jamrial> because that "int j" line must not make it into the tree under any circumstances
[03:40] <compn> jamrial : why do you want it rushed into libav ? thats now how they roll
[03:41] <jamrial> well, I wouldn't call it rushed at this point
[03:45] <iive> well, it is not like they have a competition or something...
[03:45] <iive> ;)
[04:04] <cone-551> ffmpeg.git 03Michael Niedermayer 07master:dc6b99d6b20e: avformat/movenc: Check ff_put_wav_header() return code
[04:23] <jedir0x> does avpicture_fill copy the data - or just copy the pointers to the data?
[12:42] <funman> http://ks.chui-pas.net/~fun/ffmpeg_chocolate.jpg
[13:44] <ubitux> michaelni: with which subtitles/cmd did you trigger that issue?
[13:58] <ubitux> i'm surprised ubsan doesn't have an abort mode
[14:41] <michaelni> ubitux, you mean for "avformat/mux: 2 subtitle packets could have the same DTS" ?
[14:41] <ubitux> yes
[14:41] <michaelni> IIRC the one from carl in the referenced ticket
[14:42] <ubitux> ah, missed that, my bad
[14:43] <michaelni> funman, i just woke up and looked at that pic, got me confused for a second ;)
[14:46] <BBB> hcocolate yummy
[14:46] <BBB> do we get some?
[14:54] <cone-56> ffmpeg.git 03Michael Niedermayer 07master:2e55f3e90715: avfilter/vf_lut3d: check size in parse_dat()
[14:55] <ubitux> michaelni: does it have the same pts too?
[14:55] <michaelni> -debug_ts should show it
[14:56] <michaelni> I dont remember
[14:58] <michaelni> demuxer -> ist_index:10 type:subtitle next_dts:426311 next_dts_time:0.426311 next_pts:426311 next_pts_time:0.426311 pkt_pts:7783637667 pkt_pts_time:86484.9 pkt_dts:7783637667 pkt_dts_time:86484.9 off:-86484364989 off_time:-86484.4
[14:58] <michaelni> demuxer -> ist_index:10 type:subtitle next_dts:497978 next_dts_time:0.497978 next_pts:497978 next_pts_time:0.497978 pkt_pts:7783637667 pkt_pts_time:86484.9 pkt_dts:7783637667 pkt_dts_time:86484.9 off:-86484364989 off_time:-86484.4
[14:59] <michaelni> so yes, look the same on the input side already
[15:01] <cone-56> ffmpeg.git 03James Almer 07master:fa23190a7ac9: hevcdsp: add missing header include
[15:13] <funman> michaelni: ;)
[15:14] <funman> BBB: there is lots of chocolate in Berlin
[15:36] <cone-56> ffmpeg.git 03Matt Oliver 07master:c6bf660bef8f: opencl: Make init_mtx static with volatile lock
[15:37] <BBB> funman: for me to eat chocolate, it needs to be in the same location as me
[15:45] <funman> BBB: where are you?
[15:45] <BBB> funman: ny
[15:45] <BBB> can you send me some?
[15:45] <funman> http://shop.borgodoro.it/products/libav-chocolate can
[15:45] <funman> if you were in mountain view i could have brought some next month
[15:47] <BBB> but I'm not in mtv :-p
[15:47] <wm4> doesn't this libav chocolate use the ffmpeg logo
[15:48] <BBB> anyway maybe next time you guys are in the proper city
[15:48] <BBB> :-p
[15:48] <funman> wm4: http://ks.chui-pas.net/~fun/ffmpeg_chocolate.jpg clearly does
[15:53] <nevcairiel> wm4: its the same logo :p
[18:54] <cone-56> ffmpeg.git 03James Almer 07master:8e078000010b: hevcdsp: include stddef.h for ptrdiff_t definition
[19:38] <ubitux> michaelni: why not add the TS_NONSTRICT fmt flag to teletext instead?
[19:38] <ubitux> ah my bad it's for formats meh
[19:38] <michaelni> yes, meh
[19:38] <ubitux> well i haven't work on dvb teletext
[19:38] <ubitux> i have no idea if that's normal to have subs at the same pts/ts, but i guess it makes sense
[19:39] <ubitux> but isn't pos or something suppose to make a different in order?
[20:09] <michaelni> all reordering code should maintain the order of packets with equal dts within one stream, if thats what you menats
[20:18] <ubitux> ok
[20:18] <ubitux> well i see no objection, but as i said i'm probably not the best person to review that kind of stuff
[20:28] <ubitux> seems i'll have to wait for the next gcc version to use -fno-sanitize-recover with ubsan :(
[20:29] <ubitux> it's almost useless now
[21:46] <cone-56> ffmpeg.git 03Michael Niedermayer 07master:6b9e0bf42fb3: avfilter/vf_removelogo: fix memleak on failure
[21:58] <cone-56> ffmpeg.git 03Reimar Döffinger 07master:97bcb0588916: Add missing "const" to pointer arrays.
[22:05] <Daemon404> wm4, yes fuck eurovision
[22:05] <Daemon404> gf is watching it by me
[22:05] <Daemon404> kill me now.
[22:05] <wm4> lol
[22:06] <ubitux> as long as she is just watching and not listening everything is ok
[22:06] <Daemon404> lol
[22:06] <Daemon404> i dont get eurovision
[22:06] <nevcairiel> ubitux: actually, i wouldn't agree with that
[22:07] <Daemon404> seemingly normal europeans suddenly like what seems to be x factor
[22:07] <Daemon404> but with N countries
[22:07] <ubitux> nevcairiel: ah, visual are insane as well?
[22:07] <nevcairiel> here, have this .. guy http://shrani.si/f/P/sK/2lp1q32o/3.png
[22:07] <ubitux> ahah
[22:08] <Daemon404> nevcairiel, russia and belaruse wanted him kicked off
[22:08] <Daemon404> somthing about a wasteland of sodomy
[22:08] <wm4> interesting
[22:08] <wm4> I guess in some obscene way eurovision might be interesting for the "politics"

[22:09] <iive> do russia and belaruse participate in eurovision? I thought they are not in EU.

[22:09] <Daemon404> iive, what has it got to do with EU?
[22:09] <nevcairiel> its a european thing, not a EU thing really
[22:09] <Daemon404> eurovision is much older than the EU
[22:09] <cone-56> ffmpeg.git 03Michael Niedermayer 07release/1.1:3af977d4d644: avfilter/graphdump: Fix pointer to local outside scope

[22:09] <nevcairiel> cant throw someone out of the continent :P
[22:10] <iive> never heard of it before EU
[22:10] <JEEB> it even has israel and turkey there
