[00:36:09 CEST] <you_all_suck> hey you dregs, I have an ffmpeg issue
[00:36:09 CEST] <you_all_suck> http://pastebin.com/ZX1jxxWc
[00:36:24 CEST] <you_all_suck> I'm trying to convert a series of bmp images to a video file
[00:36:41 CEST] <you_all_suck> repeated attempts have only served to frustrate my goal of doing something that NOT only should be very simple
[00:36:47 CEST] <Anoia> calling us dregs and saying we all suck is a great way to get help.
[00:36:57 CEST] <you_all_suck> but should be the minimum expectation of any video editing tool
[00:37:20 CEST] <you_all_suck> Anoia: I call em as I see em
[00:37:22 CEST] <you_all_suck> now help me
[00:38:26 CEST] <Anoia> fuck off
[00:38:45 CEST] <Anoia> (not official channel stance)
[00:39:08 CEST] <you_all_suck> I get that alot
[00:39:16 CEST] <you_all_suck> the question
[00:39:24 CEST] <you_all_suck> *the question's still open to anyone who can answer it
[00:39:37 CEST] <you_all_suck> otherwise I'm fixing to tweet about my negative experience using this tool
[00:41:37 CEST] <absent2> lol
[00:48:39 CEST] <Anoia> don't forget the #ffmpegsuxballs hashtag.
[00:49:14 CEST] <Anoia> and maybe #peoplewonthelpmeafteriinsultthem
[00:49:30 CEST] <absent2> FFMPEG fails using the slackbuild because it can't find caca, but I have libcaca installed. Works fine on my laptop but not the server. Weird.
[00:49:32 CEST] <Anoia> #nfiwhy
[01:10:28 CEST] <Anoia> no twitter post about it yet
[01:10:34 CEST] Action: Anoia goes to sleep
[01:14:10 CEST] <absent2> looks like alien bob's package installed fine, something weird with the slack package I guess
[01:20:50 CEST] <you_all_suck> well I waited here and even had enough time to take a crap
[01:20:56 CEST] <you_all_suck> and I still don't see a solution
[01:21:08 CEST] <you_all_suck> talentless hacks, all of you
[01:21:53 CEST] <you_all_suck> I won't recommend this tool to anyone else that I know and I'll shortly update my blog with my unpleasant experience with it and with the irc support channel
[01:22:11 CEST] <you_all_suck> thanks for nothing
[01:34:02 CEST] <Anoia> lol
[01:34:20 CEST] <Anoia> still not on twitter
[01:36:55 CEST] <absent2> they see me trollin
[01:36:57 CEST] <absent2> they hatin
[01:37:00 CEST] <absent2> ...
[03:01:01 CEST] <bertieb> In case there's someone here who knows now: is there a way to specify an output codec_time_base (tbc) when encoding?
[04:52:15 CEST] <troy_s> Anoia: We will miss him. I am certain that his blog and Tweets will have a tremendously adverse impact on the FFMPEG project.
[04:56:17 CEST] <ac_slater_> hey all.
[04:56:50 CEST] <ac_slater_> Im muxing some mpegts. What if I say a stream's timebase is 1/15 but I insert into the context (mux) more that 15 times a second?
[09:43:28 CEST] <feliwir> how to resolve undefined reference to `DtsProcOutputNoCopy' when linking with ffmpeg?
[09:43:46 CEST] <feliwir> i am not sure from which library that function is
[09:47:48 CEST] <feliwir> help is appreciated
[10:23:54 CEST] <chrisss123456> Hi, I have a typical nooby question: I'm trying to convert an mp4 file into an mpg file, without loss. I used the standard ffmpeg -i input.mp4 output.mpg but while the video was still in 1080p, the quality was shitty. Any help?
[10:31:01 CEST] <cbsrobot_> chrisss123456: try: ffmpeg -i input.mp4 -t 1 -q:v 0 output.mpg
[10:31:19 CEST] <cbsrobot_> and if you like the sample output, remove the -t 1
[10:31:20 CEST] <chrisss123456> cbsrobot_: thanks! what do those flags mean?
[10:31:52 CEST] <cbsrobot_> if the file is tooo heavy, you could rise the -q value
[10:36:28 CEST] <hrw> can someone point me into some howto to convert multiaudiolanguage/dvd into multiaudiolanguage/h264 something?
[10:42:06 CEST] <feliwir> does someone know if the ffmpeg vp6 decoder does actually fill the frame with ALPHA_DATA?
[10:44:22 CEST] <cbsrobot_> feliwir: I think there is commit on the ml
[10:44:48 CEST] <cbsrobot_> hrw: check for the -map option - I think there's something on the wiki
[10:45:02 CEST] <hrw> cbsrobot_: thanks
[10:45:05 CEST] <cbsrobot_> hrw: https://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option
[10:45:19 CEST] <feliwir> cbsrobot_: ml?
[10:45:24 CEST] <cbsrobot_> Mailinglist
[10:45:26 CEST] <cbsrobot_> ffmpeg-devel
[10:45:54 CEST] <feliwir> cbsrobot_: i saw that one
[10:46:20 CEST] <cbsrobot_> and ?
[11:10:01 CEST] <feliwir> how do i apply a change from the ml?
[11:14:24 CEST] <durandal_1707> git apply patch
[11:16:02 CEST] <feliwir> durandal_1707: and how to get the patch out of the mail?
[11:16:22 CEST] <rcombs> if you've got the message as a .mbox then `git am` can help
[11:17:29 CEST] <feliwir> i got it as a mail. And the mail has the patch in it like this: http://pastebin.com/mjgBiXwm
[11:17:36 CEST] <feliwir> is this already applyable?
[11:21:27 CEST] <chungy> yeah
[11:21:54 CEST] <chungy> looks like you cut off the headers.
[11:22:14 CEST] <feliwir> i applied this now
[11:22:30 CEST] <chungy> Your email client probably has a "Save as mbox" option, use that :)
[11:22:38 CEST] <feliwir> will this change already make AVFrame being filled with rgba data when decoding vp6 that has alpha?
[11:22:44 CEST] <chungy> otherwise git won't take the commit message or author information as intended
[11:24:51 CEST] <feliwir> is the patch author in here? peter ross?
[11:32:16 CEST] <JEEBsv> I think he's on the -devel channel
[11:34:56 CEST] <feliwir> ah, never saw that channel before
[11:39:43 CEST] <hrw> when 'ffmpeg -i' lists several audio tracks is there a way to get language info?
[11:40:04 CEST] <Mavrik> doesn't ffprobe list it?
[11:41:58 CEST] <hrw>     Stream #0:2: Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s
[11:41:58 CEST] <hrw>     Stream #0:3: Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s
[11:41:58 CEST] <hrw>     Stream #0:4: Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s
[11:42:56 CEST] <Mavrik> That usually means it can't recognise the language :/
[11:43:03 CEST] <hrw> ok
[11:43:31 CEST] <hrw> used mplayer to find out en/cs/pl/en-with-comments
[11:45:06 CEST] <hrw> started "ffmpeg -f concat -i /tmp/del/l -c:v copy -c:a:0 copy -c:a:2 copy -c:a:3 copy out.vob" and then can reencode video if this works
[12:02:54 CEST] <hrw> http://pastebin.com/kZiyVRK8 - what I am doing wrong? I want to copy audio streams without reencoding them and ffmpeg wants to reencode
[12:07:07 CEST] <hrw> numbers were wrong ;d
[12:09:48 CEST] <Mavrik> I think just "-codec copy" works as well :)
[12:10:20 CEST] <hrw> :D
[12:13:09 CEST] <hrw> now only make audio stream #2 -> #1 and #1 -> #2 so it will start with proper language
[12:25:38 CEST] <nick123> Anyone know what this mean "overread end of atom"
[12:26:26 CEST] <feliwir> does ffmpeg have some functionality to mask one AVFrame on top of another?
[13:03:05 CEST] <bertieb> nick123: Seems to be a warning log message (see https://ffmpeg.org/pipermail/ffmpeg-cvslog/2013-November/070705.html)
[13:05:58 CEST] <nami> hey. no way to play media with ffmpeg static on linux?
[13:07:06 CEST] <nami> there is only: ffmpeg, ffprobe, ffserver and qt-faststart in it
[13:10:24 CEST] <BtbN> If you don't build it with SDL support, no.
[13:13:00 CEST] <nami> http://johnvansickle.com/ffmpeg/
[14:54:01 CEST] <hrw> is there a way to add language tags to audio streams?
[15:13:15 CEST] <feliwir> how frequently zeranoe builds are created?
[15:15:09 CEST] <feliwir> damn there was just a build that doesn't have the changes i needed -.-
[15:20:23 CEST] <feliwir> can anyone actually confirm this works: https://www.ffmpeg.org/platform.html#Native-Windows-compilation-using-MinGW-or-MinGW_002dw64
[15:23:36 CEST] <feliwir> because i keep getting this:Unknown OS 'msys_nt-6.3'.
[15:29:14 CEST] <feliwir> can anyone please help me out with this problem?
[15:32:34 CEST] <feliwir> it also tells me to use enable cross compile (which doesn't change a thing)
[15:33:30 CEST] <feliwir> http://pastebin.com/FS0x9GT6
[15:33:35 CEST] <feliwir> (yes cl is in path)
[15:51:14 CEST] <feliwir> did noone here ever compile ffmpeg that way?
[15:55:16 CEST] <bertieb> feliwir: If no-one answers that means probably not
[15:55:47 CEST] <bertieb> But a quick search turns up https://trac.ffmpeg.org/ticket/3203 and https://ffmpeg.org/pipermail/ffmpeg-user/2012-December/011861.html which you may already have sene
[15:55:56 CEST] <bertieb> s/sene/seen/
[15:58:26 CEST] <bertieb> In fact, a search for "cl is unable to create an executable file" returns a number of results from zeranoe forums itself, which may be of use
[15:58:30 CEST] <feliwir> bertieb, it didn' really get answers
[16:01:20 CEST] <feliwir> ah i think i got it
[16:01:23 CEST] <bertieb> feliwir: Indeed, but it suggests starting points for getting futher information which are not included in your pastebin link. If you have searched and read those trac issues/ml threads/forums posts it is worth saying what you have tried
[16:01:55 CEST] <bertieb> feliwir: Since that will let people know you have done your own research before coming here
[16:02:23 CEST] <feliwir> it was using the wrong link.exe
[16:02:37 CEST] <feliwir> maybe you should mention that on the mainpage since every msys2 installation has that
[16:03:09 CEST] <bertieb> If you are referring to me, I'm just here to get help with a problem, like you
[16:03:25 CEST] <feliwir> ah okay. What's yours?
[16:03:31 CEST] <feliwir> i was talking to ffmpeg staff :D
[16:04:02 CEST] <bertieb> An email to them with a well-phrased suggestion stands more chance of being read if that's you intention
[16:04:41 CEST] <bertieb> Thanks for asking, I've posted my problem to the ml, but here it is:  https://ffmpeg.org/pipermail/ffmpeg-user/2015-June/027255.html
[16:05:18 CEST] <bertieb> (There are also a couple of posts on SuperUser relating to it)
[16:07:01 CEST] <davidpeach> hi there
[16:07:36 CEST] <bertieb> But to summarise- Small question: can I set output tbc in some way? Much longer question: can I match codec parameters to concat demux video files together
[16:07:53 CEST] <davidpeach> i was in need of some help with streaming some ffmpeg output please? I have it in place and working - i just needed some advice if possible?
[16:07:58 CEST] <feliwir> bertieb, sorry no idea
[16:08:10 CEST] <bertieb> Since I've not yet had a reply on SU or in here I suspect it is a fairly niche question
[16:08:19 CEST] <bertieb> But I'm relatively patient :)
[16:08:32 CEST] <bertieb> feliwir: Appreciate you asking anyway
[16:08:50 CEST] <bertieb> davidpeach: Ask (don't ask to ask)
[16:11:16 CEST] <davidpeach> oki. So i am using nodejs and am running the ffmpeg command (this time just creating a new video from current - no filters) and when I pipe it out in the response stream, the result is very choppy. I think the rate at which it is creating the new video is much slower than playback speed. Any advice on speeding up the creation process / better way to approach the problem?
[16:11:38 CEST] <BtbN> pur more cores into the host
[16:11:59 CEST] <davidpeach> My end goal is to use the complex filter, inserting images over the base video to create new video and piping it straight out to user.
[16:12:16 CEST] <davidpeach> currently all videos need to be made in advance (there's thousands of them)
[16:12:39 CEST] <davidpeach> BtbN : how do I do that please?
[16:12:43 CEST] <feliwir> hm. Make install is faling now :'D
[16:12:52 CEST] <BtbN> By taking out the old, slow, CPU, and putting in a new one.
[16:13:09 CEST] <BtbN> If your server is overwhelmed with a single live-transcode, i think you are out of luck with that approach for a productive public setup.
[16:13:20 CEST] <feliwir> ideas: http://pastebin.com/W02HNgA8 ?
[16:14:34 CEST] <bertieb> feliwir: Are you cross-compiling?
[16:20:19 CEST] <feliwir> bertieb, i am compiling on windows for windows
[16:20:24 CEST] <feliwir> so i guess no
[16:20:40 CEST] <bertieb> feliwir: Have you disabled cross-compilation related options?
[16:20:56 CEST] <feliwir> bertieb, i am only doing: ./configure --toolchain=msvc --enable-shared
[16:21:17 CEST] <feliwir> like the guide on the homepage told me to do
[16:22:44 CEST] <BtbN> of course make install fails on windows
[16:22:48 CEST] <BtbN> if make succeeded, you are done
[16:23:24 CEST] <bertieb> feliwir: Can you run what has been built?
[16:23:51 CEST] <feliwir> BtbN, why the homepage says to do make install then?
[16:24:17 CEST] <BtbN> It does?
[16:24:23 CEST] <feliwir> bertieb, i have no idea where it is located
[16:24:31 CEST] <feliwir> BtbN, https://www.ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows
[16:24:34 CEST] <bertieb> feliwir: Which homepage? I'e searched for "make install" on http://ffmpeg.org and get no results
[16:24:55 CEST] <BtbN> that make install seems strange there
[16:24:59 CEST] <BtbN> just don't run it
[16:25:32 CEST] <feliwir> BtbN, i can't find any .lib or .dll files in my ffmpeg folder
[16:25:45 CEST] <BtbN> But make succeeded without errors?
[16:26:09 CEST] <feliwir> yes, only a couple warnings
[16:26:28 CEST] <BtbN> You should have the ffmpeg binaries in your build dir then
[16:26:30 CEST] <feliwir> wait, nevermind
[16:26:46 CEST] <feliwir> http://pastebin.com/2rw0vJVy
[16:27:18 CEST] <bertieb> feliwir: that's included in your make install output
[16:27:31 CEST] <bertieb> Did the previous 'make' command also generate that?
[16:27:36 CEST] <feliwir> bertieb, also occurs when running make
[16:27:37 CEST] <feliwir> yes
[16:28:09 CEST] <bertieb> Hmm. Do you need the shared libraries option? You could try a static build
[16:29:54 CEST] <feliwir> bertieb, i tried that before
[16:29:59 CEST] <feliwir> also no files generated
[16:30:07 CEST] <bertieb> Same error?
[16:30:19 CEST] <feliwir> i gonna try "make" now instead of "make -j4"
[16:30:27 CEST] <feliwir> maybe it doesn't like that
[16:30:45 CEST] <davidpeach> Thanks anyway
[16:33:08 CEST] <Eduardo_1> hello
[16:39:50 CEST] <Eduardo_1> I just downloaded, compiled, and installed ffmpeg 2.7.1, to use nvenc. It works with no problem at all, but i'm unable to use 2 pass encoding, the log file that ffmpeg generates always has size 0.
[16:39:50 CEST] <Eduardo_1> the command is: ffmpeg -i input.mp4 -y -vcodec nvenc -2pass 1 -preset llhq -b:v 1000k -profile:v main -pass 1 -an -f mp4 test.mp4
[16:43:00 CEST] <Eduardo_1> how should i do it?
[16:52:47 CEST] <feliwir> bertieb, that was the error :D
[16:53:02 CEST] <feliwir> someone knows what are the possible reasons of avformat_open_input failure?
[16:53:30 CEST] <bertieb> feliwir: Presumably some race condition in the makefile then, glad you got the compile tow ork tho
[16:53:48 CEST] <feliwir> thanks for the help
[16:55:06 CEST] <feliwir> the return value is 0xbebbb1b7
[17:00:10 CEST] <feliwir> what does it mean?
[17:00:17 CEST] <feliwir> the file specified does exist 100%
[17:07:22 CEST] <feliwir> the error is this: Invalid data found when processing input
[17:07:33 CEST] <feliwir> this morning it worked on linux -.-
[17:07:39 CEST] <feliwir> now on windows i get this
[17:55:45 CEST] <feliwir> can someone tell me where that error comes from?
[18:24:56 CEST] <delarita_> Do someone know something about how to influence pic_init_qs_minus26 value in a ffmpeg commnand ?
[20:16:50 CEST] <Odyssey> Hi everyone. I'm using GNU/Linux since a few months and I want my system to be as free as possible. FFmpeg is a free sotware package, but why is it in the "non-free" repository on debian ? (I'm very new in the GNU/Linux world, so I'm not an expert ^_^)
[20:19:30 CEST] <relaxed> Odyssey: "apt-cache show ffmpeg" lists Filename: pool/main/f/ffmpeg/ffmpeg_2.7.1-1_amd64.deb
[20:21:17 CEST] <bertieb> Odyssey: Also, some parts have (had?) non-free licenses
[20:22:41 CEST] <relaxed> so, pool/main isn't pool/non-free
[20:25:18 CEST] <Odyssey> So there's two repository ? One with non free package and one without them ?
[20:26:27 CEST] <relaxed> Where are you getting that it's non-free?
[20:28:02 CEST] <Odyssey> Because I have to install Ffmpeg but I have to add this line in the source.list : "deb http://www.deb-multimedia.org jessie main non-free", that's why I'm asking if it's free or not ^_^
[20:28:23 CEST] <relaxed> which debian version?
[20:28:37 CEST] <relaxed> ffmpeg should be in jessie and unstable
[20:29:21 CEST] <relaxed> er, it's not in Jessie
[20:29:40 CEST] <Odyssey> (Yes, I'm on Jessie)
[20:30:41 CEST] <relaxed> it's in unstable not, but I don't recommend using external repos for anything. If you want a gpl'd version you can use my static build. http://johnvansickle.com/ffmpeg/
[20:31:04 CEST] <relaxed> I'm meant "it's in unstable now" :)
[20:32:16 CEST] <Odyssey> Thank you :)
[20:32:45 CEST] <relaxed> Debian will include it in the next release
[20:57:41 CEST] <postmodern> what is the precision of dvd chapter start-times?
[20:57:48 CEST] <postmodern> they seem to always end in 0 or 500 ms
[22:26:37 CEST] <Eduardo_1> hello, anybody knows how to make 2 pass encoding using nvenc ?
[22:48:00 CEST] <scottcall> Hello!  I have a quick Is this possible question for you all.   I have a video that I need to replace about 1 minute of in the middle.  I know I can take the original, cut it into two pieces and then concat it with the new middle part but I was hoping to do it all in one swoop with select filters and a concat.  While the first segment (from file A) gets put into the final file just fine, but when the 2nd segment (from the new file) is append
[22:48:01 CEST] <scottcall> I get buffer overflow errors.  My questions is, is this possible or should I just go ahead the split the file up before running a second command to stitch them back together?
[22:51:42 CEST] <scottcall> Okay will do.  I just trimmed my command down to remove some of my complications I added in debugging Ill put the pastebin link up in a sec
[22:54:44 CEST] <scottcall> http://pastebin.com/C81d0XVj
[23:01:44 CEST] <llogan> does the output not play correctly?
[23:05:22 CEST] <scottcall> llogan- the output plays out, but only contains the first segement, So the first 2773 frames are copied from input 0 to the output but where input 1 should come in is when the right before the overflow errors start.  Ive let it sit for 5-10 minutes of errors to see if it picks back up but it doesnt.   Ive even tried just using two different select filters from the same input and concating them but they have the same issue, buffer queue overflow
[23:05:22 CEST] <scottcall> soon as the first select segment is complete.  Ive used select for a while to split a file into pieces and multiple selects with multiple outputs work just fine, just seems trying to skip the step of writing them out causes problems.
[23:09:32 CEST] <scottcall> I did eventually get [output stream 0:0 @ 0x1d296a0] 100 buffers queued in output stream 0:0, something may be wrong. after 10 minutes or so and then had to kill -9 the process because it wouldnt respond to the q command
[23:10:39 CEST] <xdexter> Hello, Hello, I installed ffmpeg through rpmfusion, when I check the version appears to min "ffmpeg version 12:10:15", however I see that the site shows version 2.7, is that correct?
[23:11:04 CEST] <llogan> scottcall: i had to do something similar lately for a client's prores files. i was just lazy and stream copied the segments to individual output files, then used concat demuxer, but i re-encoded the final output instead of stream copied.
[23:11:48 CEST] <scottcall> Thats pretty much where I was at, I figured if I could streamline the process great, but I realize Im asking a lot of it ;-)
[23:12:05 CEST] <llogan> xdexter: version 12:10:15 means nothing in FFmpegese. run "ffmpeg" in console and see what version it's using
[23:12:56 CEST] <xdexter> llogan, http://pastebin.com/uksDZEFG
[23:13:03 CEST] <llogan> scottcall: another idea is to try -ss and -t as input options for each segment instead of (a)trim with concat filter. i've never tried that though.
[23:14:10 CEST] <llogan> xdexter: 0.10.15. that's an old branch. 2.7 is most recent release, but general users are recommended to use a build from current git master. releases are basically for distros and other distributors.
[23:14:21 CEST] <llogan> http://johnvansickle.com/ffmpeg/
[23:14:24 CEST] <scottcall> -ss isnt frame accurate (at least in my experience) and since Im subbing in a 1:1 match (basically the same video with different localized credits) I need that precision.
[23:14:49 CEST] <llogan> i was hoping you didn't need such accuracy
[23:15:17 CEST] <scottcall> Its okay, Ill just live with temp files and tell the department requesting the feature they need to allow a little more time.  I really do apreciate you taking a look tho
[23:15:30 CEST] <xdexter> llogan, hmm, ok
[23:15:42 CEST] <llogan> or https://trac.ffmpeg.org/wiki/CompilationGuide/Centos
[23:16:41 CEST] <xdexter> llogan, Through some rpm package I can not use the latest version?
[23:16:50 CEST] <llogan> not that i know of
[23:17:48 CEST] <xdexter> llogan, Ok, thankyou
