[00:08:37 CEST] <drwx> 12:41 < drwx> hi, could anyone look at this bug? https://trac.ffmpeg.org/ticket/2975
[00:08:40 CEST] <drwx> 12:41 < drwx> also, https://trac.ffmpeg.org/ticket/4487 looks like a duplicate
[01:14:47 CEST] <penthief> Do you want a bug report containing something like the following http://paste.lisp.org/display/147622 ? (Incorrect resolution with x11grab causes a segfault when switching windows.) 
[01:16:15 CEST] <penthief> I can also chuck you a 7 meg core dump if you tell me where to put it.
[01:18:12 CEST] <penthief> Possibly introduced with a6674d2e7771dbf7a4a5556f5e126be83cadac96 (Aug 24 2014).

[16:16:02 CEST] <saste> kierank, michaelni, do you know why there is no multi-program support in the mpeg-ts muxer?
[16:16:33 CEST] <saste> see http://trac.ffmpeg.org/ticket/4525

[17:19:32 CEST] <cone-503> ffmpeg 03foo86 07master:e80b2b9c8171: avcodec/dca_parser: Extend DTS core sync word and fix existing check
[17:26:07 CEST] <j-b> So, what's the status/mess with DCA?
[17:26:43 CEST] <ubitux> stall game?
[17:26:43 CEST] <Compn> i think they are arguing about some encoder patch 
[17:27:33 CEST] <Daemon404> "just use foo86's library"
[17:28:03 CEST] <j-b> I mean, there is a new DTS-HD decoder in libav, but was it merged here? There was different code here for DTS-HD too, right? And there is the foo86 decoder, too, now?
[17:28:23 CEST] <Daemon404> j-b, the foo86 one is the only one with a fixed point dca core implementation
[17:28:27 CEST] <Daemon404> i.e. actually lossless
[17:29:22 CEST] <j-b> Daemon404: ok. The libav one was merged in FFmpeg or?
[17:29:57 CEST] <Daemon404> hell if know
[17:30:18 CEST] <cone-503> ffmpeg 03Michael Niedermayer 07master:8a710ddc7c11: avcodec/libx264: Remove cleanup code, its uneeded since FF_CODEC_CAP_INIT_CLEANUP
[17:32:24 CEST] <Compn> its chaos! 
[17:32:25 CEST] <Compn> :P
[17:44:09 CEST] <wm4> j-b: it was merged, and disabled by default
[17:44:31 CEST] <wm4> at least AFAIK
[17:44:53 CEST] <wm4> and the libdcadec wrapper exists in both libs too now
[17:45:16 CEST] <j-b> wm4: disabled, because of innaccuracy?
[17:45:38 CEST] <j-b> what about X96 ?
[17:45:39 CEST] <wm4> and I think there were other problems with it too? maybe nevcairiel knows details
[17:45:48 CEST] <wm4> no idea
[17:46:07 CEST] <wm4> if you want some feature, I'd say foo86 is likely to implement it in his lib
[18:27:53 CEST] <cone-503> ffmpeg 03Michael Niedermayer 07master:14e9a20083c9: avformat/mpegts: Also parse the FMC descriptor if the codec has not been identified yet
[18:29:44 CEST] <nevcairiel> j-b: wm4: libav disabled it as well by default on my suggestion, to avoid regressions in decoding, which do exist, and X96 is not supported
[18:30:12 CEST] <nevcairiel> dcadec from foo86 supports all of the things in perfect accuracy however, the only missing feature is DTS Express, aka. LBR
[18:32:43 CEST] <kierank> That is a separate codec
[18:34:19 CEST] <nevcairiel> well it uses the same extension header, and presumably shares similar coding techniques
[18:35:57 CEST] <kierank> It's different totally
[18:36:11 CEST] <kierank> It's like e-ac3 vs ac-3
[18:36:20 CEST] <kierank> But it is marketed like it is similar
[18:36:31 CEST] <nevcairiel> which share a lot of code in avcodec? :d
[18:36:49 CEST] <kierank> Yes share code because of headers etc
[18:36:56 CEST] <kierank> But it's a bigger gap
[18:37:01 CEST] <j-b> nevcairiel: regressions? how can there be regressions?
[18:37:12 CEST] <j-b> I mean, the core is the core, no?
[18:37:30 CEST] <nevcairiel> j-b: trying to parse HD parts, failing, causing odd behavior, like switching between 5.1 and 7.1 decoding every other audio frame
[18:39:51 CEST] <j-b> nevcairiel: do you have samples for such fails?
[18:40:19 CEST] <nevcairiel> somewhere, i gave them to the libav people when it was first merged
[18:54:04 CEST] <rcombs> any particular reason why libavformat/tls.c doesn't verify certs by default?
[19:01:19 CEST] <wm4> because it just breaks shit
[19:01:48 CEST] <rcombs> what kind of shit
[19:01:52 CEST] <rcombs> (maybe someone should fix that)
[19:02:43 CEST] <BtbN> I think enablding it would break a bunch of stuff.
[19:03:17 CEST] <BtbN> And cause a bunch of angry people, because their self-signed certs suddenly don't work anymore.
[19:03:51 CEST] <rcombs> there's an AVOption to disable it
[19:04:04 CEST] <BtbN> Yes, but it breaks existing setups.
[19:04:17 CEST] <BtbN> changing defaults allways does
[19:04:32 CEST] <rcombs> biggest issue I see is that it doesn't seem to pull in the system cert bundle by default
[19:05:23 CEST] <wm4> rcombs: maybe the main reason is because nobody wants to fight these crappy tls libs
[19:06:10 CEST] <rcombs> it's not like self-signed cert users haven't had to disable verification in every other piece of software they use (or actually add their certs to their cert bundle, in which case this isn't a problem if that's used [which it isn't but should be])
[19:10:41 CEST] <rcombs> hmm, curl (which does this pretty reliably cross-platform) uses OSX's and Windows's built-in TLS facilities (Secure Transport and Schannel), and on Linux the default CA bundle for OpenSSL/GNUTLS and all the other libs they support is a configure option
[19:16:36 CEST] <wm4> make libavformat use libcurl
[19:18:20 CEST] <rcombs> I've seen that done, actually
[19:18:53 CEST] <rcombs> quite some time ago, before lavf's protocol support was as stable
[19:19:09 CEST] <rcombs> (wait a sec why is avio part of lavfnever mind)
[19:20:37 CEST] <nevcairiel> i dont bundle any tls/ssl support in my windows builds right now because openssl is a license nightmare, and gnutls is terrible to build on windows
[19:20:54 CEST] <nevcairiel> i was meaning to see if building a schannel native-windows th ing would be as terrible as people claim..
[19:25:19 CEST] <rcombs> Secure Transport does let you provide your own read/write callbacks, so tls.c could continue to use lavf's tcp interface as usual
[19:25:24 CEST] <rcombs> hmm, I might actually do this
[20:00:55 CEST] <ramiro> are aac frames always standalone? (as in they don't depend on data from previous frames)
[20:22:10 CEST] <cone-503> ffmpeg 03Michael Niedermayer 07master:828759ed9afa: avcodec/cook: Remove unneeded #if
[20:25:36 CEST] <michaelni> about ssl certs, everything should check them by default IMHO, its more secure
[20:28:34 CEST] <wm4> lol
[20:28:36 CEST] <wm4> "secure"
[20:28:48 CEST] <wm4> a remote server can make ffmpeg connect anywhere you want
[20:34:16 CEST] <rcombs> wm4: http://suptg.thisisnotatrueending.com/archive/24232601/images/1365921834628.jpg
[20:36:59 CEST] <wm4> at least http redirects and things like MOV reference files and HLS (which open further requests)
[20:44:53 CEST] <rcombs> well that's the server you asked for (which could be verified) directing you somewhere else
[23:23:53 CEST] <cone-837> ffmpeg 03Michael Niedermayer 07master:f8fa392a2edb: avfilter/vf_vignette: force per frame evaluation if per frame variables are used
