[01:45] <active8> hi. when i .configure ffmpeg with --enable-x11grab, if fails and config.log says ERROR: Xext not found
[02:10] Last message repeated 1 time(s).
[02:10] <active8> iwas able to do this before
[02:43] <rcombs> active8: you may need to install Xext; if you already have it, check config.log to see exactly what failed
[02:46] <active8> rcombs, finally from http://matrafox.info/error-xext-not-found.html i found libXext-devel missing -- https://ffmpeg.org/pipermail/ffmpeg-user/2013-November/018668.html  listed a few. one, i had, one i installed and it didn't help, and the other was not available from a NORMAL CentOS repo "Normal" meaning not RPMFarce or most of the stuff at rpmfind
[02:48] <active8> rcombs, do you have access to the spec file to build the ffmpeg rpm?
[03:18] <rcombs> active8: no, and I'm not sure how that's relevant
[03:20] <active8> long story - i'll spare you
[04:51] <reisio> is there a straightforward way to rip a stream that 'ffplay' plays?
[04:52] <reisio> or better yet, watch it and rip it simultaneously
[05:09] <fling> Why are people encoding with black borders? -> http://lurkmore.so/images/6/69/Blacklines.JPG
[05:14] <klaxa> because they think they know what they are doing while in reality they do not
[05:20] <emhs> Dudes, is there a way to generate a video from images and audio, but set the cut of each image to a specific time?
[05:20] <emhs> Like, it starts with Frame01.png, and cuts to Frame02.png at x seconds,
[05:20] <emhs>        Frame03.png at y seconds, and so on.
[06:09] <fling> emhs: try openshot
[07:30] <mark4o> emhs: if you want to do it with ffmpeg: http://superuser.com/a/619843/2087
[07:36] <rcombs> is it possible to set an OPT_BOOL to 0 on CLI?
[07:36] <rcombs> (I ask because `print_stats` is -1 by default and is an OPT_BOOL, so I don't think there's a way to set it to 0)
[07:56] <emhs> mark4o: Thanks. Wound up going with Lightworks, but I'll keep that in mind when 1sec resolution'll work. D'you know if concat can do a finer resolution than that?
[08:13] <mark4o> emhs: yes, the ffconcat duration takes any valid duration
[09:45] <rjp421> is there a length limit to a librtmp output string?
[09:45] <rjp421> the long stream URI works fine when publishing from FMLE, but when i use ffmpeg the server complains about not getting the full URI string (bottom msg), http://pastebin.com/ktPxFvCr
[09:45] <rjp421> the adobe multicast configurator forces me to use that long of a string...
[09:45] <rjp421> is there a way to make ffmpeg send the entire rtmp output URI?
[11:38] <c_14> rjp421: You might want to try asking on the user mailing list and if that doesn't work try opening an issue on trac.
[14:50] <Amnesia> question, how could I convert a dvd to x264?
[14:50] <Amnesia> ffmpeg -i concat:VTS_01_0.VOB\|VTS_01_1.VOB\|VTS_02_0.VOB\|VTS_02_1.VOB\|VTS_02_2.VOB\|VTS_02_3.VOB|VTS_02_4.VOB -vcodec libx264 -preset veryslow -qp 0 -acodec copy output.mkv doesn't do the job
[14:53] <Amnesia> https://privatepaste.com/b603e6b3a3
[14:56] <c_14> You forgot the \ in front of |VTS_02_4.VOB
[14:56] <c_14> As seen in line 2
[14:56] <c_14> But I'm not sure that the concat protocal will work for that.
[14:58] <Amnesia> c_14: ah ty:P
[16:14] <sine0> can someone please tell me if this plays without fail for them www.pcyard.co.uk/sample.mvk
[16:14] <sine0> bugger
[16:14] <sine0> www.pcyard.co.uk/sample.mkv
[16:15] <Fjorgynn> m
[16:15] <c_14> works for me
[16:15] <sine0> there are no blips ?
[16:15] <sine0> or grey frames
[16:16] <c_14> None I can see.
[16:16] <sine0> ok. then there is something wrong my end.
[16:16] <sine0> it plays on my hardware player but not in vlc
[16:16] <c_14> Try updating vlc.
[16:17] <sine0> its the latest
[16:17] <sine0> im wondering what build flags i have missed
[16:17] <sine0> is there a way of playing with ffmpeg
[16:17] <c_14> ffplay
[16:17] <c_14> With update, I meant try the nightlies
[16:17] <sine0> ffplay -i file
[16:18] <c_14> just ffplay file
[16:18] <sine0> wow it works!!!!!
[16:18] <sine0> sweet
[16:19] <sine0> at least i can watch it for now. that must mean it IS vlc
[16:19] <sine0> do you know how i can start play halfway through the movie ?
[16:19] <c_14> try using -ss
[16:20] <c_14> you have to give it a position in seconds
[16:20] <sine0> hmm ok
[16:20] <c_14> though HH:MM:SS should also work
[16:42] <kaotiko> hi
[20:19] <__jack__> hah
[20:19] <__jack__> (ups)
[20:31] <wodim> __jack__ are you from python?
[20:32] <__jack__> yep, I'm a builtin
[20:35] <Alina-malina> guys
[20:35] <Alina-malina> i need some program for adding video effects to slideshow, something custom, do you know anything?
[20:53] <Nosomy|off> Alina-malina, avisynth, but is script oriented
[21:22] <Alina-malina> Nosomy|off, ok let me try that
[21:40] <Fjorgynn> thank you Alina-malina
[22:00] <edoceo> You know how some MP4 play sooner than others in my browser?  Whats that called? How to make my mp4s have that and how to verify it's present?
[22:07] <JodaZ> edoceo, they have the moov atom early in the file, common tool to do that would be qt-faststart, ffmpeg might be able to do it by itself now, and alternatively you can make the mp4 "progressive" somehow, but the qt-faststart method is the most commonly cited one
