[00:28:27 CEST] <jamrial> thardin: lmao, that's dedication :p
[00:34:08 CEST] <thardin> :]
[00:34:16 CEST] <thardin> well, I was curious
[00:34:27 CEST] <thardin> and as I write, toy codecs are useful for these things
[00:34:58 CEST] <thardin> if we can get performance issues on a codec from 1991, what possible nightmares await for say av1?
[00:37:19 CEST] <thardin> I'm of course quite for adding very conservative constraints, but they have to be added at the very start
[00:39:37 CEST] <thardin> if cvid requires that the entire frame be encoded, then the decoder should reject files that don't behave. instead we get this shotgun parsing garbage. I hate it
[00:46:12 CEST] <thardin> oh wait, you meant the mxf thing
[00:46:36 CEST] <thardin> or not, I dunno. it's getting late
[00:52:21 CEST] <jamrial> thardin: no, i was talking about the cinepak stuff with win3.1 :p
[00:56:21 CEST] <thardin> I got even got 24-bit graphics to work (:
[01:00:13 CEST] <J_Darnley> Wow
[01:00:40 CEST] <J_Darnley> I only every got to use 3.1 on a black and white laptop
[01:04:34 CEST] <thardin> we had 16 colors, which was ok until I noticed a friend of mine somehow got 256 colors on his machine
[02:35:07 CEST] <cone-690> ffmpeg 03Andreas Rheinhardt 07master:c294f38c91f4: avformat/matroskadec: Fix seeking
[02:37:44 CEST] <cone-690> ffmpeg 03Andreas Rheinhardt 07release/4.2:299e0dff1fbc: avformat/matroskadec: Fix seeking
[06:16:57 CEST] <philipl> BtbN: so even after fixing the 0x0 problem, I just get a green screen from nvdec. What was that guy looking at?
[06:17:25 CEST] <philipl> I tried generating a sample with ffmpeg itself and I see the same thing as the samples I have from the nokia phone.
[06:17:45 CEST] <philipl> Guess I should email him.
[08:28:40 CEST] <Compnn> Lynne, the reason i ask who you are, not even talking about personal details like name. but what other projects you could work on where you insult multiple developers and name call
[08:31:40 CEST] <durandal_1707> Compnn:  stop insulting him
[08:32:02 CEST] <Compnn> did you just assume Lynne 's gender ?
[08:34:14 CEST] <pross> 'stop insulting it?' seems more even insulting..
[08:34:28 CEST] <Compnn> 'them' would be acceptable
[08:34:29 CEST] <TheAMM> ("them"...)
[08:34:31 CEST] <Compnn> pross speaks
[08:34:43 CEST] Action: pross types
[08:35:11 CEST] <pross> i sadly don't have much to contribute
[08:35:15 CEST] <Compnn> is ok
[08:35:26 CEST] <Compnn> at least you are still around
[08:35:56 CEST] <pross> setting up color filters in mutt for codecs/formats i am interested in has really helped
[08:39:16 CEST] <Compnn> i am not sure why more people dont setup email filters to only review xxx.c and yyy.c and trash all the rest
[08:39:26 CEST] <Compnn> for those people who only contribute or follow certain code of course
[08:41:09 CEST] <durandal_1707> because certain developer which name should not be spoken like to touch everything and break it at random
[08:43:25 CEST] <Compnn> Lynne, you committed code without attributing copyright
[08:44:10 CEST] <Compnn> well carl committed your patch
[08:44:24 CEST] <Compnn> Carl if you are reading this, Lynne's code has no copyright
[08:46:04 CEST] <Compnn> in the past this was an issue with many developers who did not like anonymous or Elvis authors
[08:46:43 CEST] <durandal_1707> which code?
[08:46:48 CEST] <Compnn> j-b, how much anonymous code in your codebase ?
[08:47:16 CEST] <Compnn> durandal_1707, http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/aarch64/opusdsp_neon.S
[08:47:47 CEST] <TheAMM> Elvis authors?
[08:47:55 CEST] <BBB> prores :D
[08:48:10 CEST] <BBB> which caused us to have two decoders o_O
[08:48:23 CEST] <BBB> when did we turn into mplayer?
[08:49:48 CEST] <Compnn> no one offered to combine the two decoders :P
[08:49:54 CEST] <durandal_1707> since Compnn
[08:50:12 CEST] <Compnn> i cant remember current status of prores codec numbers :D
[08:50:32 CEST] <durandal_1707> its growing
[08:50:47 CEST] <Compnn> apple users seem happy with it
[08:50:59 CEST] <durandal_1707> lies
[08:51:17 CEST] <Compnn> think it would be easy to common code the two decoders somewhat...
[08:51:38 CEST] <durandal_1707> first apple users are not using ffmpeg
[08:52:45 CEST] <BBB> Compnn: I don't think anyone wants to have two decoders
[08:52:49 CEST] <durandal_1707> Compnn will write win32 wrapper for lavc in 2020
[08:53:24 CEST] <Compnn> BBB, right. but removing one will cause some issues with some people maybe
[08:53:25 CEST] <Compnn> or maybe not
[08:53:50 CEST] <Compnn> in that thread, VLC should not maintain its own demuxers, codecs etc either
[08:54:04 CEST] <Compnn> why are multiple projects reinventing wheels we can all reuse
[08:54:16 CEST] <durandal_1707> you just insulted j-b
[08:54:34 CEST] <Compnn> he may agree with me
[08:59:11 CEST] <durandal_1707> Compnn: are you ok that one person singlehandly controls ffmpeg various resources
[08:59:43 CEST] <Compnn> durandal_1707, if you are upset with alex b's handling of the domain name, you should post to the ml
[09:02:40 CEST] <Compnn> durandal_1707, you could commit more things instead of wasting time on irc
[09:02:52 CEST] <Compnn> night
[09:03:49 CEST] <durandal_1707> on vacation
[09:04:54 CEST] <Compnn> durandal_1707, you could vacation more things instead of wasting time on irc
[09:13:36 CEST] <Compnn> https://support.apple.com/en-us/HT200321
[09:13:38 CEST] <Compnn> ehehe
[09:13:49 CEST] <Compnn> Unauthorized codec implementations
[09:13:49 CEST] <Compnn> In some instances, unauthorized codec implementations have been used in third-party software and hardware products. Using any unauthorized implementation (such as the FFmpeg and derivative implementations) might lead to decoding errors, performance degradation, incompatibility, and instability.
[09:23:33 CEST] <Compnn> BBB, another prores encoder http://mogurenko.com/2019/05/17/prores-quality/
[09:48:25 CEST] <kurosu> 184K vs 163k (and thus uploaded a version 163k too)
[09:51:48 CEST] <kurosu> but still much better
[10:01:52 CEST] <thardin> hum, I see one or two companies on that list that I know use ffmpeg internally
[10:03:18 CEST] <thardin> unless they added a plugin for apple's encoder
[10:25:51 CEST] <kurosu> the weird thing is the encoding is almost constant quantizer and uses the proxy quality/quant matrices
[10:26:06 CEST] <kurosu> probably some further eob optimization
[11:24:56 CEST] <durandal_1707> full parsing of aac celp bitstream done
[11:25:09 CEST] <durandal_1707> now to do avtual decoding
[15:11:44 CEST] <kierank> Prores encoder is clearly a (l)gpl violation
[15:51:05 CEST] <durandal_1707> kierank:  why?
[15:51:48 CEST] <kierank> That guy in the blog post
[15:51:56 CEST] <kierank> He ships FFmpeg binary
[15:52:56 CEST] <durandal_1707> well he can do with it whatever can be done
[15:53:46 CEST] <kierank> Also compn talking nonsense as always
[15:59:39 CEST] <durandal_1707> compn is ffmpeg mascot
[18:02:56 CEST] <durandal_1707> michaelni: why carl and reimar are on @security ml and I'm not? this is outrageous discrimination.
[18:21:58 CEST] <cone-728> ffmpeg 03Limin Wang 07master:ad3ef00ce513: avfilter/f_select: yuv will use Y plane only for scenecut detect
[18:21:58 CEST] <cone-728> ffmpeg 03Limin Wang 07master:6a3bdf314886: fate: add accurate_rnd+bitexact sws_flags for fate-gifenc
[18:26:33 CEST] <durandal_1707> this user is really multimedia dumb
[18:27:05 CEST] <durandal_1707> now  we  link also to torrents
[18:27:49 CEST] <durandal_1707> this not legal and they might drop from service
[18:35:10 CEST] <durandal_1707> michaelni: why nobody cant take your job? why are you so special?
[19:00:15 CEST] <cone-728> ffmpeg 03Marton Balint 07master:a82f8f2f10d0: avformat/avio: add avio_print_string_array and avio_print
[19:00:16 CEST] <cone-728> ffmpeg 03Marton Balint 07master:61b4daf78ce0: avformat/assenc: optimize writing dialogs
[19:00:17 CEST] <cone-728> ffmpeg 03Marton Balint 07master:95fa73a2b48f: avformat/avio: remove 4k limit from avio_printf
[19:12:08 CEST] <durandal_1707> michaelni: why are you ignoring me? is that because i reviewed so many of your ( only ) fuzz patches?
[19:49:17 CEST] <cone-728> ffmpeg 03Limin Wang 07master:6866c54ee474: avfilter/showinfo: support Content Light Level information
[20:10:30 CEST] <durandal_1707> jamrial: you basically ignored nicolas request
[20:11:10 CEST] <jamrial> what was it?
[20:12:49 CEST] <durandal_1707> sizeof content light i think in showinfo
[20:15:42 CEST] <jamrial> he didn't request anything in that thread
[20:16:57 CEST] <jamrial> someone else asked for a check that can't be done from outside libavutil
[20:19:29 CEST] <durandal_1707> not explicitly
[20:32:05 CEST] <DMI-1407> hi, only a small question... im using ffmpeg in version N-34549-g13b7781, (since 2011)
[20:32:23 CEST] <DMI-1407> i used gdigrab on June this year
[20:32:33 CEST] <DMI-1407> (on windows 7)
[20:32:46 CEST] <DMI-1407> now it tells me ffmpeg is not supporting gdigrab
[20:32:56 CEST] <DMI-1407> i think its because some last updates
[20:33:06 CEST] <DMI-1407> is that known already ?
[20:33:15 CEST] <BtbN> Maybe don't use an 8 year old version?
[20:33:55 CEST] <DMI-1407> was gdigrab depricated ?
[20:34:26 CEST] <BtbN> No idea, but nobody here is gonna give you support for an almost 9 year old version, other than telling you to update it.
[20:37:05 CEST] <nevcairiel> I dont really see any relevant changes in gdigrab, maybe your version was just build without it
[20:38:03 CEST] <nevcairiel> gdigrab was only officially added in 2014, so no clue what your 2011 v ersion did
[20:41:15 CEST] <DMI-1407> hm oki dunno that thanks
[20:52:19 CEST] <durandal_1707> DMI-1407: why so old version?
[20:52:38 CEST] <DMI-1407> dunno it worked
[20:52:56 CEST] <durandal_1707> for what?
[20:53:07 CEST] <DMI-1407> screencapture pixel by pixel
[20:53:40 CEST] <DMI-1407> i use it to capture my screen to frames stored as png
[20:54:04 CEST] <DMI-1407> then i can edit and compress them to an video
[21:10:58 CEST] <guest278776> hi what's the command to capture a portion of a youtube clip plz?
[21:11:29 CEST] <guest278776> 720size or whatever the default is
[21:11:35 CEST] <durandal_1707> no such thing
[21:11:41 CEST] <guest278776> : ( really?
[21:12:19 CEST] <guest278776> i can't say i want from 1:20 to 3:20 and it gets downloaded to where i specify?
[21:12:55 CEST] <guest278776> i can only download the who clip?
[21:13:02 CEST] <guest278776> whole
[21:13:21 CEST] <BtbN> ffmpeg does not support downloading from youtube to begin with, so you should ask whoever made the tool you are using
[21:14:17 CEST] <guest278776> oh, but it is capable of clipping an already downloaded video for me?
[21:16:01 CEST] <guest278776> could it be piped from a curl get command that grabs the video then passes it to ffmpeg, the clip is saved then the original deleted? is that possible at all? thx
[21:18:05 CEST] <BtbN> You can't just "curl grab" a YouTube video
[21:18:16 CEST] <BtbN> Also, this is the wrong channel.
[21:21:13 CEST] <durandal_1707> lol kierank
[21:21:25 CEST] <kierank> why lol
[21:21:31 CEST] <durandal_1707> how he violates gpl?
[21:21:57 CEST] <kierank> he ships ffmpeg binary with --enable-gpl
[21:22:00 CEST] <kierank> with his own encoder
[21:22:33 CEST] <durandal_1707> but his stuff is linked with his lib 
[21:22:53 CEST] <kierank> it's gpl
[21:22:55 CEST] <kierank> doesn't matter
[21:23:55 CEST] <kierank> he remove my comment
[21:23:57 CEST] <thardin> doesn't he publish the source code?
[21:24:03 CEST] <thardin> of his own encoder?
[21:24:05 CEST] <durandal_1707> he have blog and this on github so send him dmca
[21:25:19 CEST] <kierank> thardin: he has some code but i don't think it's the whole thing
[21:25:38 CEST] <kierank> as usual guy says "ffmpeg is shit" then violates copyright
[21:25:45 CEST] <durandal_1707> his code is his company code
[21:26:42 CEST] <thardin> ah
[21:26:48 CEST] <thardin> yeah that sounds like a gpl violation
[21:27:05 CEST] <durandal_1707> he did previously sent patches to prores but he was ignored
[21:29:32 CEST] <kierank> on new years eve lol
[21:29:36 CEST] <kierank> when people have better things to do
[21:33:23 CEST] <thardin> did he even ping them?
[21:33:45 CEST] <durandal_1707> nope
[21:47:24 CEST] <durandal_1707> kierank: i see no point in such bug reports
[21:48:02 CEST] <kierank> ok
[21:48:27 CEST] <durandal_1707> if nothing gonna change
[21:49:34 CEST] <durandal_1707> and michaelni does not care
[21:55:16 CEST] <durandal_1707> kierank: how to post dmca to github page?
[21:55:35 CEST] <kierank> https://github.com/contact/dmca
[21:58:18 CEST] <michaelni> durandal_1707, how would you feel if someone pinged you every day and claimed something random about you ? please stop this
[21:59:44 CEST] <durandal_1707> michaelni: post counter claims if you have them, instead you just hide and ignore
[22:00:50 CEST] <jamrial> durandal_1707: you're obsessed. you pinged him in the middle of a discussion about some dude violating the gpl for no other reason than because you wanted to
[22:01:48 CEST] <kierank> durandal_1707: michaelni: neither of you are exactly in the right
[22:02:49 CEST] <durandal_1707> yes, i am obsessed with our beloved leader. fuzz patches make me fuzzy
[22:03:47 CEST] <jamrial> nothing better to help your cause than admitting you're harasing him
[22:04:03 CEST] <durandal_1707> only on irc
[22:07:47 CEST] <durandal_1707> and if you call this harassing when i only want respect and not discrimination so be it
[22:08:17 CEST] <nevcairiel> respect is earned, you are not on a good way currently
[22:09:23 CEST] <durandal_1707> my patience is very low, i started being nice but when i keept getiing ignorred i changed
[22:09:37 CEST] <nevcairiel> too bad, no respect for you then
[22:10:36 CEST] <durandal_1707> nevcairiel: you are not helping and you are of limited use to the project
[22:11:03 CEST] <nevcairiel> i'm not trying to help you, and you can keep your bad insults :)
[22:12:02 CEST] <durandal_1707> you never respected me either
[22:12:07 CEST] <jamrial> durandal_1707: you were not ignored, you got replies. you simply didn't get the one you wanted
[22:12:17 CEST] <nevcairiel> of course not, look at how you act, thats not respectable attitude
[22:12:25 CEST] <jamrial> and you're not going to get more if your reaction at not getting things exactly like you wanted to is increased harassement
[22:15:42 CEST] <durandal_1707> i was ok at start but i see more and more how pathetic this project was from start
[22:16:47 CEST] <durandal_1707> voting comitee, more like vomiting comitee
[22:19:15 CEST] <jamrial> yes, the voting comitee left a lot to be desired, nobody will disagree with you in that regard
[22:19:23 CEST] <durandal_1707> it sad that kostya was right in most of things
[22:19:56 CEST] <kierank> cehoyos: ndi problem is fixed, no, it is removed?
[22:20:14 CEST] <cehoyos> I don't think it was fixed at least nobody has claimed so yet
[22:20:38 CEST] <durandal_1707> fixed in what sense?
[22:20:47 CEST] <kierank> we removed it from ffmpeg
[22:21:27 CEST] <nevcairiel> and they stopped shipping it as well
[22:21:47 CEST] <durandal_1707> but violation remains
[22:22:13 CEST] <kierank> ok technically true
[22:22:50 CEST] <cehoyos> The ticket is not about the sad removal of ndi from FFmpeg but their copyright violation
[22:27:52 CEST] <kierank> i am not sad about removing a proprietary protocol in which the manufacturer attacked open source developers for reverse engineering
[22:43:42 CEST] <durandal_1707> i expect that all commits which cause decoder to not return frame causing vfr in cfr to be effectively reverted or disabled
[22:45:32 CEST] <kierank> I will fork if it happens to important decoders (h264, mpeg2)
[22:46:40 CEST] <durandal_1707> i expect that voting comitee is no more called
[22:47:40 CEST] <durandal_1707> i expect one true leader in FFmpeg to show up finally
[22:47:59 CEST] <kierank> all forms of committee have been and will continue to be nonsense
[22:48:17 CEST] <kierank> it is like soviet union
[22:48:25 CEST] <kierank> we tried to change this at vdd
[22:48:33 CEST] <kierank> same with code of conduct
[22:48:43 CEST] <kierank> even linux kernel has a real code of conduct
[22:48:47 CEST] <kierank> only it's us left 
[22:48:52 CEST] <kierank> with stupid bill and ted thing
[23:00:33 CEST] <thardin> did anyone try talking to him in private?
[23:00:43 CEST] <thardin> like calling them out immediately is possibly not the best approach
[23:04:00 CEST] <durandal_1707> kierank sent comment on blog or github i think
[23:05:18 CEST] <durandal_1707> michaelni: you havent made vfr from cfr in msrle case, this inconsistency must end
[23:22:32 CEST] <tjones> I'm trying to generate the most complete ffmpeg that I can.  I have no concerns for tainted or non-free code. Do anyone have pointers to the required external libraries and configure options?
[23:23:08 CEST] <tjones> Primarily for Linux 64bit, but maybe Windows
[23:34:18 CEST] <thardin> configure --help has quite a bit of this info
[23:35:16 CEST] <tjones> I was just curious if someone had already been down this road.  The configure --help gives some good info on what it understands, but what about adding the external libs?
[23:36:21 CEST] <jamrial> configure --help will give you the list of external libraries you can link to
[23:40:28 CEST] <tjones> It must be a forest / trees issue because while I see the list of --enable options, I'm not getting the relationship between built-in versus external libraries.
[23:43:47 CEST] <tjones> The reason that I ask is because a setting to enable a bunch that I thought should be there resulted in errors.
[23:44:44 CEST] <tjones> I was looking to find a list of external libs to install to make sure things were covered.
[23:48:25 CEST] <tjones> Ah - I've located what I was looking for in the "General Documentation" - Supported External Libraries, Formats, Codecs or Features.
