[00:57] <chriys> hi all I'm running ubuntu 12.04 and I'm trying to set up http live streaming using ffmpeg and ffserver. I found no full tuto on how to set it up. Does some of you have links ? [01:22] <dahat> hrm... per the folks over in #x264dev, I should (and am) be spitting out an libx264.lib file, however ffmpeg's configure is not able to locate it at all... even if I rename it to x264.lib (which ffmpeg seems to be looking for) [08:09] <hanshenrik> cats [08:28] <anshul_mahe> I am trying to compile ffmpeg with libx264 on cygwin using mingw compiler [08:29] <anshul_mahe> but it configure says libx264 not found [08:29] <anshul_mahe> here are my command http://pastebin.com/DwbRGVid [08:30] <anshul_mahe> I would like to clear that I have already compiled x264 using same mingw compiler that I am using for ffmpeg [08:30] <anshul_mahe> and path of pkg-config are set and showing linx264 installed [08:32] <anshul_mahe> here are details of config.log [08:32] <anshul_mahe> http://pastebin.com/XXRyRVmd [08:37] <anshul_mahe> I dont know, what ffmpeg configure is trying to use for cflags of x264, where should I find that? [08:55] <bramgg> Would it be possible to record a PC game with FFmpeg without it being displayed on the screen? (ie the game is running an a background process) [08:59] <anshul_mahe> I figured out that configure does not look for pkg-config of x264, used extra-flags to solve my problem [09:01] <K4T> how I cna check libx264 version in my ffmpeg? [09:22] <anshul_mahe> @K4T x264 --version [10:16] <Olivius67> Hello [10:22] <Olivius67> I'm using the following cmd to split a streamable mp4 into 60seconds parts: ffmpeg.exe -i in.mp4 -codec copy -f segment -segment_time 60 -reset_timestamps 1 out%02d.mp4 [10:23] <Olivius67> The problem is that the resulting parts require a lot of buffering (around 6 MB) before they start playing with jwplayer. By Googling around I have found a fix to this by passing the following cmd to each part: MP4Box.exe -inter 500 outxx.mp4. The resulting parts stream smoothly after a very short buffering (around 500KB). [10:23] <Olivius67> Now, is there a way I could integrate directly this 'fix' in the initial ffmpeg cmd I use to split and thus avoid the extra mp4box step? [11:17] <BtbN> Olivius67, you can't just split a video (without reencoding) at random points. You have to split at I frames. Also, mp4 is not ideal for fast start. Use a more simple format, like flv, or add the faststart atom [11:33] <Olivius67> Btbn: mp4 is the format I need to use (basically the project states that there will also be a direct mp4 download link for each part. Thus, as I don't want to multiply video format I would preffer sticking to mp4 for both streaming and direct download) ). The mp4box cmd I used (I confess I don't know much about what I'm doing here) actualy generated parts that fast started good enough for me. [11:33] <Olivius67> How can I have ffmpeg split at correct I frames? [11:37] <fdf> Hi, I have this error when using "pad=width=300:height=170:x=0:y=40:color=black" -> Cannot find color 'color=black' any idea what i`m doing wrong? [11:41] <fdf> http://pastebin.com/qtRV70X5 [12:13] <BtbN> Olivius67, if you want to stream it, keep in mind that mp4 is not streamable [12:14] <BtbN> if you want to offer static downloads, mp4 is somewhat ok, but not for streams, as it can't start at random positions [12:18] <Olivius67> Well when post processed with mp4box.exe -inter 500. The parts were just as good as non splitted original mp4: fast start and fast forwarding are smooth. [12:19] <Olivius67> I just would like to reproduce the magic of mp4box into my initial ffmpeg split cmd. And thus avoid the extra mp4box step. [13:11] <vlatkozelka> hi [13:12] <vlatkozelka> when i use -copyts with -f segment -segment_time x ... instead of recording files of x length it starts recording one frame long videos (with correct stamp tho ) [13:13] <vlatkozelka> <vlatkozelka> when i use -copyts with -f segment -segment_time x ... instead of recording files of x length it starts recording one frame long videos (with correct stamp tho ) [13:13] <vlatkozelka> sorry i think i DC while typing that [13:17] <vlatkozelka> is it some kind of bug with TS or .. ? [13:19] Last message repeated 1 time(s). [13:31] <vlatkozelka> ok sorry about repeating but im not sure if i got disconnected before or after i pressed enter so ... [13:32] <vlatkozelka> <vlatkozelka> when i use -copyts with -f segment -segment_time x ... instead of recording files of x length it starts recording one frame long videos (with correct stamp tho ) [14:40] <sepero> Re-encode h264 without quality loss http://video.stackexchange.com/questions/12523/ffmpeg-re-encode-libx264-with... [14:47] <ubitux> sepero: encode the first time in lossless, otherwise not possible [15:09] <Kolizer> ABL CAA:85? [15:11] <Kolizer> O >48= [15:11] <sfan5> sepero: re-encoding is probably the only way to do what you want to acheive [16:17] <Wader8> hello [16:17] <Wader8> no offense [16:17] <Wader8> by why is FFMPEG documentation such a POS [16:18] <spaam> in what way is it Point of sale? [16:18] <Wader8> and ...why do I seem to have to spend 2 days to research to find some help in some 2-3 year old forum post in the corner of the web ? [16:18] <Wader8> never mind ... here's my issue http://forum.videohelp.com/threads/366893-FFMPEG-deinterlace-convert-to-squa... [16:19] <Wader8> my biggest problem is that ffmpeg keeps changing the command line namings without updating the documentation, can't find anything on YADIF just doesn't exist, deinterlacing, nonexistant on ffmpeg.org [16:20] <Wader8> all i find is some text-only ticket postings with a ton of dumped hard to read outputs [16:22] <Wader8> I am sorry it's just me maybe, maybe it's supposed to be like this [16:23] <Wader8> I am patient now, that i found this chatroom [16:23] <Fjorgynn> I see [16:24] <saste> Wader8, -vf yadif [16:24] <saste> what's so hard about it? [16:25] <Wader8> well it took me way more time to find this with google than I expected, especially when the ffmpeg documentation doesn't mention this odd name at all, but never mind back to work ... [16:26] <Wader8> and i suppose to use some 1:-1:1 or something after yadif ? [16:26] <Wader8> found that somewhere [16:27] <Wader8> anyways, what about square pixels, can i remove the awful pixel aspect ratio and render in 854x480 ? [16:28] <sacarasc> Wader8: http://ffmpeg.org/ffmpeg-all.html#yadif-1 [16:28] Action: sacarasc shrugs. [16:29] <Wader8_> there was network disconnect [16:30] <sacarasc> Did you get this link: http://ffmpeg.org/ffmpeg-all.html#yadif-1 ? [16:33] <Kolizer> What is wrong http://dumpz.org/1189119/ ? [16:33] <Kolizer> help [16:34] <sacarasc> Can you pastebin the ffmpeg output, too? [16:34] <Kolizer> I? [16:34] <sacarasc> Yes. [16:34] <Kolizer> sacarasc: [16:34] <Kolizer> yes [16:37] <Kolizer> here http://dumpz.org/1189122/ [16:39] <Kolizer> And? [16:42] <sacarasc> What problem are you having? [16:43] <Kolizer> low fps [16:43] <Kolizer> very low fps [16:44] <sacarasc> The video? Or the encoding? [16:44] <Kolizer> max 9 and drop [16:45] <Kolizer> everywhere [16:47] <Kolizer> What's the problem? [16:49] <Kolizer> you run this code sacarasc? [16:50] <sacarasc> Someone who might know what's happening could be around soon, and as they will have the information, they will have an easier time. [16:52] <Kolizer> You code works? sacarasc [16:52] <sacarasc> I haven't tried it. [16:53] <sacarasc> What is your CPU usage like when you run the command? [16:53] <Kolizer> start plz? [16:54] <Kolizer> 12% max [16:54] <Kolizer> or 6% [16:59] <Kolizer> you run code? sacarasc [17:00] <sacarasc> No, I am not at a Linux machine, so I can't/. [17:00] <sacarasc> You're going to probably have to wait for someone else, anyway. They'll have the information needed, though. [17:01] <Kolizer> I think who in "-filter_complex overlay=" bug [17:02] <Kolizer> >:o [17:02] <Kolizer> bug!!!

How would I do that? [20:22] <dahat> Quick sanity question... when building ffmpeg under MinGW for Windows with the VS2013 compiler and using the --enable-libx264 argument when running configure... which .lib file should it go looking for? libx264.lib or x264.lib? [21:39] <mr_lou> Hello. Can ffmpeg create an "audio only" video from a wav file? (for blu-ray audio) [21:44] <mr_lou> Nevermind. [21:44] <mr_lou> tsMuxer did the trick. [21:48] <gcl5cp> is there a x264 irc channel? i'm searching all motion parameter to minimize cpu usage building slideshow-video [21:52] <Devrim> ehm [21:52] <Devrim> try #x264 [21:52] <Devrim> like [21:52] <Devrim> just a guess [21:52] <Devrim> ^^ [21:57] <t4nk773> hi everyone!
