[00:00] <SeanDuncan_> I get the possibility of piping to x264.  it's just that piping defeats the purpose of why x264opts exists in ffmpeg in the first place.  :) That's just me complaining tho :)
[00:00] <durandal11707> i'm not talking about piping
[00:01] <ElMarikon> or u try out if it hides in ffmpeg's -x264-params
[00:01] <ElMarikon> that is a strange other option there...
[00:02] <SeanDuncan_> @durandal11707 I didn't quite know what you meant when you said "!pb"
[00:03] <SeanDuncan_> cna you elaborate?
[00:04] <SeanDuncan_> oh
[00:04] <SeanDuncan_> oops, didn't see your question there
[00:04] <SeanDuncan_> yes, I made sure it works with x264
[00:04] <iive> SeanDuncan_: !pb is command to the helper bot, to provide instructions how to use pastebin
[00:05] <SeanDuncan_> @ durandal110707 yes, I made sure it works with x264
[00:05] <SeanDuncan_> thanks @iive .  color me red
[00:07] <SeanDuncan_> @durandal11707 my .qp file looks just like the one described (format wise)
[00:08] <SeanDuncan_> at http://mewiki.project357.com/wiki/X264_Settings#qpfile
[02:06] <Zarx> does ffmpeg support trimming by frame range, or only by time?
[02:07] <durandal11707> Zarx: see select filter
[02:07] <durandal11707> it support both by time-pts and frame number
[02:10] <durandal11707> but this is not for -c copy only case ...
[02:10] <Zarx> where can i find documentation for using the select filter?
[02:13] <Zarx> thanks
[02:20] <otters> so if ffmpeg can't do it, what IS good for editing mp4 chapters?
[03:13] <plut0> any suggestions on a good crf # for encoding bluray movies?
[03:14] <zap0> depends on the content
[03:15] <zap0> if it were that simple to state, don't you think it'd be automated by now
[03:15] <plut0> i would think so
[03:28] <shakaponk> hello folks, compiling  ffmpeg like in the ffmpeg ubuntu compilation guide getting error xext not found
[03:28] <shakaponk> what is missing?
[03:29] <klaxa> xext apparently
[03:29] <klaxa> even though this is not an ffmpeg command, please paste everything regardless
[03:31] <shakaponk> hold on, different machines
[03:32] <shakaponk> pastie.org/7745934
[03:33] <shakaponk> doin the same steps as here: http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
[03:33] <shakaponk> stepinstalling ffmpeg
[03:33] <klaxa> try installing libxext-dev
[03:33] <klaxa> then run configure again
[03:34] <klaxa> um... did you install all the packages listed at the top?
[03:34] <shakaponk> yes i did... that's the package name i would like to know, couldn't find it
[03:35] <klaxa> so can you install it now or is it somewhat missing?
[03:35] <shakaponk> what is the package name for xfixes? quite the same error
[03:35] <klaxa> libxfixes-dev
[03:36] <klaxa> these files are listed in the preparation packages for compilation at the top of the page you linked
[03:36] <shakaponk> seems to work, movin on, thx a lot
[03:37] <shakaponk> klaxa: oh i guess i lost track and executed for servers instead... now i see it
[03:37] <shakaponk> thx anyway for your input
[03:37] <klaxa> heh

[14:14] <chrisbuchholz> Hey guys. Can somebody tell me what the exit code 5 mean in ffmpeg?
[14:35] <chrisbuchholz> I am trying to run ffmpeg from php by running exec('/usr/local/bin/ffmpeg') but i get error code 5
[14:54] <xlinkz0> chrisbuchholz: run with -report and check the log
[14:55] <chrisbuchholz> im afraid it doesnt work. Just get empty output and error code 5
[14:57] <xlinkz0> if no output then you have a broken ffmpeg instalation
[14:57] <xlinkz0> fix that
[16:46] <bugggg> anyone here with a samsung tv have a working set of arguments for ffmpeg that will make it play 1080p full sbs 3d movie trailers? the half sbs ones work just fine
[18:47] <DooMMasteR> hmm
[18:47] <DooMMasteR> maybe someon can help
[18:48] <DooMMasteR> ffmpeg version 1.2 Copyright (c) 2000-2013 the FFmpeg developers  knows -start_number
[18:51] <DooMMasteR> ffmpeg -start_number 0767 -i IMG_%04d.JPG -s 1280:-1 -r 5 -vcodec libx264 -crf 15 test.mkv
[18:52] <DooMMasteR> Unrecognized option 'start_number'
[18:52] <DooMMasteR> is the return for that sequence -.-
[18:55] <DooMMasteR> hmm on another ffmpeg version that line works fine -.-
[18:59] <klaxa> http://ffmpeg.org/ffmpeg-formats.html#image2-2
[19:33] <CalimeroTeknik> er, is that normal? ffmpeg: relocation error: ffmpeg: symbol swr_get_class, version LIBSWRESAMPLE_0 not defined in file libswresample.so.0 with link time reference
[19:50] <CalimeroTeknik> is this supposed to work? I get either the error up there with the -loop 1 option, or a video that lasts for a fraction of second http://ffmpeg.org/trac/ffmpeg/wiki/Create%20a%20video%20slideshow%20from%20images
[19:53] <manitu> hi ho.. i have a little question.. i recovered videos using testdisk, but ffmpeg gives me that error now: "Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), 1920x1080): unspecified pixel format"
[19:53] <manitu> i have another, working files from that camera.. is there any way to manually define those parameters?
[19:53] <manitu> i want to convert mov to mp4
[19:54] <CalimeroTeknik> yes indeed, you can force these
[19:54] <manitu> it already writes the 1920x1080 down, but how can it not find the pixel format.. or is that something else
[19:57] <CalimeroTeknik> try x264
[19:57] <CalimeroTeknik> or variants like x264rip-tmod-git
[20:03] <WilliamWS> hi
[20:04] <WilliamWS> how fast is ffmpeg in matter of accessing a camera and creating a image file from a single frame? Some extras, the processor is very limited and memory is very low
[20:05] <pzich> I think it frequently depends on the camera drivers, actually
[20:05] <pzich> in terms of getting the camera powered up and ready to go
[20:05] <WilliamWS> My point is, ffmpeg is a good way to make this or it will have a inferior speed compared with other options like mplayer, etc?
[20:06] <pzich> I haven't personally tried it, but I doubt ffmpeg/mplayer would make a big different in the whole process
[20:06] <WilliamWS> the processor in question is a pentium MMX 266MHz with 64MB RAM under linux
[20:07] <WilliamWS> I would like to make a video stream from this machine, but... yeah I know...
[20:07] <bugggg> ah it looks like people are awake now, i'll re-ask something that i asked earlier...
[20:07] <bugggg> anyone here with a samsung tv have a working set of arguments for ffmpeg that will make it play 1080p full sbs 3d movie trailers? the half sbs ones work just fine
[20:08] <WilliamWS> ffmpeg can keep the camera running and get frames only when a particular event happens?
[20:09] <WilliamWS> ffmpeg has too many options and really I took a long time on the docs to "understand" something usefull.
[20:09] <WilliamWS> Sorry if I am asking something stupid.
[20:09] <manitu> CalimeroTeknik, how to configure that? other video has Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 14729 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc
[20:10] <SeanDuncan_> @manitu: you may want to try adding '-probesize 5000000 -analyzeduration 500000'
[20:11] <SeanDuncan_> sometimes that helps ffmpeg to figure it out
[20:11] <durandal_1707> SeanDuncan_: why you keep adding @ before nick?
[20:12] <SeanDuncan_> the colorspace, I mean
[20:13] <manitu> SeanDuncan_, doesn't work also.. normal videos taken by the cam works, but the problem is that they are recovered (my girlfriend deleted :/ ).. looks like it couldn't recover all meta-data.. i hope they are not broken now
[20:15] <WilliamWS> manitu you should delete girlfriend to avoid this in the future.
[20:15] <WilliamWS> to prevent*
[20:15] <manitu> WilliamWS, i know, but baby still needs the food
[20:15] <WilliamWS> manitu that sad =/
[20:15] <WilliamWS> hahahah
[20:16] <manitu> :D
[20:16] <WilliamWS> If is from some interest I am compiling ffmpeg on the refered machine right now
[20:23] <CalimeroTeknik> manitu, if I were you I'd just concat your video with some of the beginning of a file that has the same format
[20:25] <CalimeroTeknik> dd if=validvideo bs=1024 count=1024 |cat brokenvideo > trythis ; mplayer trythis
[20:28] <WilliamWS> 2:38h to complete ffmpeg compilation
[20:28] <WilliamWS> on a 266MHz processor 64MB RAM Debian Squeeze
[20:29] <WilliamWS> not that bad I thought I would take longer
[20:33] <WilliamWS> surely ffmpeg can do it faster than mplayer and fswecam
[20:33] <WilliamWS> cool lol
[20:35] <WilliamWS> lol I can even make a "decent" movie using ffmpeg on this machine
[20:35] <WilliamWS> I did not got it even with opencv or some v4l withery
[20:35] <WilliamWS> witchery*
[20:35] <manitu> CalimeroTeknik, i tried it and it's still broken hmm
[20:37] <manitu> CalimeroTeknik, the really first line is nearly the same
[20:38] <WilliamWS> what is the less resource (processor) hunger format to use on a video?
[20:38] <manitu> niko^A|^M&mdat^@^@^@^B and niko^K^LfGmdat^@^@^@^B
[20:38] <WilliamWS> I am using mp4 right now, but I do not know...
[20:38] <manitu> is the a bit changed part
[20:49] <WilliamWS> the Debian ffmpeg version returns this [video4linux2 @ 0x8748a60]Wrong size (0x0) /dev/video0: Error while opening file
[20:49] <WilliamWS> but the one I jsut compiled worked fine
[20:49] <WilliamWS> why the debian version of ffmpeg can not open the camera?
[20:50] <WilliamWS> I did: ffmpeg -f video4linux2 -i /dev/video0 -vframes 120 output.mp4
[21:21] <durandal_1707> WilliamWS: debian version is very old fork of ffmpeg
[21:22] <WilliamWS> I see, thank you
[21:23] <WilliamWS> anyways I already compiled it. I compiled it because the debian pkg did not worked then I thought it was sme hardware issue.
[21:23] <WilliamWS> hardware compatibility issue*
[21:27] <Jordan_> So I'm going to be including ffmpeg.exe as gplv2 along side my proprietary, what all do I need to do? I just have a FFmpeg License.txt file in my install dir. http://pastebin.com/sJzi3XFe
[21:27] <Jordan_> Just want to make sure I comply etc.
[21:29] <Jordan_> is that all I need to do?
[21:30] <Rathann> Jordan_: read the GPLv2
[21:30] <Rathann> if in doubt, ask a lawyer
[21:31] <Jordan_> Ok give me 30 mins to read thouroughly
[22:03] <Jordan_> the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does
[22:04] <Jordan_> depends on what the program does, real explicit
[22:04] <Jordan_> no one could judge that and no lawyer is going to know that either
[22:23] <Jordan_> JEEB there?
[22:26] <WilliamWS> Jordan_ do not take me bad but your mother are covered by some licence?
[22:26] <WilliamWS> I mean, she gave birth to you and now you are her property?
[22:28] <Jordan_> if i 7z ffmpeg and x264 how small can i make it cuz i'm getting 80mb?
[22:28] <Jordan_> but the 7z i extracted that included binaries was 25mb
[22:28] <WilliamWS> ok I will let this law stuff aside and keep quiet and as well ignored.
[22:29] Action: WilliamWS makes silence
[22:29] <Mavrik> Jordan_, basically you'll have to be able to show exact source of ffmpeg as you distribute it
[22:30] <Mavrik> Jordan_, if you link against it your code will also have to be covered with GPL compatible license
[22:30] <Jordan_> no not according to Section 2, there are 3 possibilites
[22:30] <Mavrik> if you only invoke it then no
[22:30] <Jordan_> I mean section 3
[22:30] <Jordan_> I don't link, but i do use its output
[22:31] <Mavrik> output doesn't matter.
[22:31] <Jordan_> i use the CLI
[22:31] <Mavrik> GPL covers the code, not what software produces
[22:31] <Jordan_> ffmpeg.exe stderr output as well as the encoded video
[22:32] <Jordan_> not necessarily all I can tell you is that it depends
[22:32] <Jordan_> someone was too lazy to explain it further
[22:32] <Mavrik> again, GPL covers the software source code
[22:32] <Mavrik> not the products of running a compiled executable
[22:34] <Jordan_> Mavrik output from the Program is covered only if its contents constitute a work based on the Program
[22:34] <Jordan_> and that depends
[22:35] <Mavrik> "ok".
[22:35] <Jordan_> so the answer is to anyone that uses output must be it depends, and no one knows
[22:36] <Jordan_> What does "You must cause"
[22:36] <Jordan_> what do they mean by "cuase"
[22:38] <Jordan_> Actally 2 doesn't apply to me I didn't make any modifications
[22:38] <Jordan_> (Section 2)
[22:41] <Jordan_> wtf how is the source 87mb!!!
[22:41] <Jordan_> after 7zip
[22:43] <Jordan_> unless i can get it to 2-3mb range i'll just include a written offer
[22:56] <Jordan_> OK so it looks like the largest usage of disk is the .git folder by far
[22:56] <Jordan_> can I delete that with no problem, that's not actual source
[22:58] <iive> Jordan_:  that's the whole source repository :P
[22:58] <Jordan_> so i can delete that right
[22:59] <iive> i guess you don't want to distribute it, since people can just pull it from ffmpeg git repository.
[22:59] <Jordan_> i doubt anyone would ever even look at it
[22:59] <Jordan_> but that is not what GPL is referring to right
[23:01] <iive> nope. I doubt that you have committed your changes in it.
[23:06] <Jordan_> so now 7mb still kind of high
[23:07] <Jordan_> what's the best compression available
[23:26] <Jordan_> 7mb is just too much, I will include written offer
[23:52] <Zarx> can the -progess option in ffmpeg be redirected to stderr, or only to a url or file?
[23:53] <sacarasc> http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-3.html assuming you're on *nix.
[23:53] <Zarx> windows actually
[23:54] <sacarasc> Then I don't know.
