[00:00] <burek> grab it to an image file
[00:00] <burek> and use what-the-font
[00:00] <burek> :)
[00:00] <Zeeflo> yea
[00:00] <Zeeflo> excactly
[00:16] <Zeeflo> What the hell!
[00:16] <Zeeflo> Its not creating a stream with the subtitle!
[00:17] <Zeeflo>  -vf "scale=1280:720,subtitles=wolfman.srt"
[00:18] <Zeeflo> [Parsed_subtitles_1 @ 0x2750800] Neither PlayResX nor PlayResY defined. Assuming 384x288
[00:18] <Zeeflo> but its not in the output file!
[00:19] <saste> Zeeflo, you on Mac?
[00:19] <Zeeflo> no
[00:19] <Zeeflo> its being encoded on a debian headless server
[00:20] <Zeeflo> with bureks latest build
[00:20] <Zeeflo> i think maybe, i need to install some fonts..
[00:20] <Zeeflo> i cant think of anything else
[00:20] <saste> Zeeflo, dunno but i used the subtitles filter before and it works fine
[00:20] <Zeeflo> perhaps the ms-fonts
[00:20] <saste> may be a libass issue
[00:21] <Zeeflo> could it not be because of missing fonts?
[00:21] <Zeeflo> but then it should give me a warning shouldnt it?
[00:21] <saste> Zeeflo, yes this is what i suppose
[00:21] <Zeeflo> ill try and install ms fonts
[00:21] <burek> [Parsed_subtitles_1 @ 0x2750800] Neither PlayResX nor PlayResY defined. Assuming 384x288      <-    that's just a warning, nothing more
[00:21] <saste> but with libass/fontconfig you never knows
[00:21] <burek> did you use -vcodec copy
[00:22] <Zeeflo> nope
[00:22] <Zeeflo> ill pastebin the whole thing
[00:22] <Zeeflo> http://pastebin.ca/2303615
[00:22] <Zeeflo> but I do suspect its because its missing system fonts
[00:23] <burek> could you provide complete output
[00:23] <Zeeflo> sure
[00:24] <saste> Zeeflo, loglevel debug may help
[00:25] <Zeeflo> yea
[00:26] <Zeeflo> but i do have absolutely no fonts installed..
[00:26] <Zeeflo> the server is brand new
[00:26] <Zeeflo> http://pastebin.ca/2303620
[00:26] <Zeeflo> ms fonts is the msttcorefonts right?
[00:27] <saste> yes fontconfig issue
[00:27] <Zeeflo> and i assume its gonna want the arial font
[00:27] <saste> i find a bit weird that libass doesn't complain hard and exits though
[00:27] <Zeeflo> most likely
[00:27] <Zeeflo> Yes
[00:28] <Zeeflo> I would have gotten a warning like i mentioned earlier
[00:28] <Zeeflo> but it did not complain
[00:29] <Zeeflo> im installing the corefonts and gonna try again
[00:44] <Zeeflo> Works flawlessly
[00:44] <Zeeflo> Yeaha!
[00:44] <Zeeflo> no need to convert to ass anymore!
[00:49] <Zeeflo> I will say Adieu and be on my merry way again!
[00:49] <Zeeflo> have a splendid evening!
[02:51] <PMacDiggity> Hello, I'm having some trouble with libfaac, using this command: "ffmpeg -i $1 -codec:1 libx264 -q 16 -s 1920x1080 -vf yadif=0:0 -pix_fmt yuv420p -acodec libfaac -ab 192k $1_x264.mp4" I get this output: http://pastie.org/5700798 which, best as I can figure says the audio should be 192k like I asked, but when I listen to it (VLC/FFplay?QT), or extract the stream with QuickTime it says it's 33kbps, and sounds like it, any ideas?
[02:52] <klaxa> i think it's generally advised to use fdk-aac for aac encoding
[02:53] <PMacDiggity> ok, thanks
[03:00] <llogan> PMacDiggity: what is the -q 16 for?
[03:00] <llogan> if ffmpeg is interpreting that as -q:a 16, then it may be ignoring your -ab
[03:01] <llogan> because -q:a and -b:a (or -ab) are mutually exclusive
[03:02] <PMacDiggity> thanks, I'll check that as well
[03:04] <llogan> and libx264 ignores -qscale if -q is being applied to the video. that is why -crf 23 (the default) is being applied to your video stream
[03:09] <PMacDiggity> yup, that was it, thanks
[03:14] <llogan> PMacDiggity: consider using -q:a (range is 0-250) instead of -b:a with libfaac.

[03:51] <Fedcomp> hi. Can i ask?
[03:51] <klaxa> always
[03:52] <Fedcomp> how to connect two ffmpeg?
[03:52] <Fedcomp> i mean i want to send some file from pc 1 over network to pc 2
[03:52] <klaxa> piping over ssh maybe?
[03:52] <Fedcomp> pc 2 will receive it and encode. It looks stupid but it's for livestreaming
[03:52] <klaxa> or using udp directly
[03:52] <Fedcomp> not fits for livestream
[03:53] <Fedcomp> tell me please how to do it over udp
[03:53] <Fedcomp> i tryed some ways but i dunno how exactly to do it.
[03:53] <Fedcomp> ffmpeg doesn't looks like want to listen port
[03:54] <Fedcomp> ffmpeg -re -i "output.flv" udp://192.168.0.103:1924
[03:54] <Fedcomp> pc1
[03:54] <Fedcomp> ffmpeg -i udp://127.0.0.1:1234 test.flv
[03:54] <Fedcomp> not working
[03:54] <Fedcomp> oops, udp://192.168.0.103:1924 both
[03:54] <Fedcomp> not working.
[03:55] <klaxa> 192.168.0.103 is the first computer?
[03:55] <Fedcomp> second
[03:55] <Fedcomp> first one is 192.168.0.100
[03:55] <klaxa> then try that ip instead
[03:55] <klaxa> you stream to your local network point, then kinda grab it from there with the second ffmpeg instance
[03:56] <klaxa> it's like when you access a website, google doesn't push the data to you, you pull it from them
[03:56] <Fedcomp> okay i'll try now.
[04:06] <Fedcomp> on local machine sending and receiving working just fine. On linux machine old ffmpeg 2010 year
[04:06] <Fedcomp> is there any possible problems with ffmpeg 2010?
[04:06] <Fedcomp> built on Jan 29 2012 23:56:18 with gcc 4.1.2 20080704 (Red Hat 4.1.2-51)
[04:07] <klaxa> can you get a newer one working? compiling from source would be the best option for most optimized results
[04:08] <Fedcomp> i tryed to compile ffmpeg once, there's a lot of dependecies.
[04:08] <Fedcomp> i'll try probably
[07:30] <zabidin> hi
[07:30] <zabidin> can ask about ffmpeg here?
[07:31] <zap0> yes
[07:35] <zabidin> i'm compiling from source for sles11 sp1. using this command: ./configure --enable-gpl --enable-libmp3lame --enable-libvorbis --disable-yasm
[07:36] <zabidin> i get this error: http://pastebin.com/WpEfQsYZ
[07:36] <zabidin> i have install libvorbis but still get those error.
[07:53] <beware> can i use ffmpeg to remux an avi without anu junk chunks etc to make it more compact?
[07:53] <beware> any*
[09:42] <_jm> hello, ffprobe shows an error on some media file (contains h264 stream), can someone help with the meaning of the error ?
[09:44] <_jm> the exact message is: missing picture in access unit with size XX
[09:46] <_jm> this message appears several times and the sizes is equal to my SPS and PPS NALU
[09:49] <_jm> full output is here: http://pastebin.com/sQ7xiG4U
[09:50] <_jm> the stream begins with SPS, PPS and an IDR but i still see some garbage when i play the file
[10:27] <TeknoJuce> is there a way to get ffserver to capture and stream with less than 1ms of delay on a smaller clocked device like a 500Mhz processor, I can get this from MPEG_Streamer but not from ffmpeg is MPEG_Streamer based on anything to do with ffmpeg?
[10:44] <b_jonas> I would like to encode only a particular set of frames from a video, given by a list of timestampts (or list of frame numbers). How do I do that?
[11:18] <klaxa> b_jonas: look at -ss and -t
[11:23] <b_jonas> klaxa: the problem is, I don't want an interval of consecutive frames
[11:23] <klaxa> ah um... hmmm...
[11:24] <klaxa> i assume those frames you want are not in equal time-dinstances? if they are, see http://ffmpeg.org/trac/ffmpeg/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video
[11:24] <b_jonas> indeed
[11:25] <b_jonas> if they're equal time distances, I could just use a framerate
[11:25] <klaxa> true
[11:25] <klaxa> the inefficient and naive process would be to go through the video n times for n frames and always extract the desired frame
[11:25] <klaxa> but that would be... well inefficient and naive
[11:26] <b_jonas> that would be slow, yes
[11:26] <b_jonas> another inefficient process would be to decode all frames then delete the ones I don't need
[11:27] <Mavrik> mornin
[11:31] <b_jonas> hmm, there's a "select" filter that can keep and drop frames, though I'd have to pass a complicated expression to it to compare with a list
[11:37] <powerkill> hello
[11:39] <powerkill> is there a ffmpeg guru present ?
[11:42] <simonec77> Hi , I'm triyng to compile ffmpeg libraries (I have download c99wrappr.exe ecc.. from the network, I do not build from myself) with msvc toolchain, whit enable shared and DEBUG, but I got an error, thi is my  "config.log" file is:http://pastebin.com/8NV2U8EM
[11:43] <simonec77> any idea?
[11:57] <viric> simonec77: '-m' are not parameters for the msvc toolchain
[11:57] <viric> ah
[11:57] <viric> well, I don't know c99wrappr at all.
[11:58] <powerkil_> viric do you code on ffmpeg ?
[11:58] <viric> not at all.
[11:59] <viric> Take me as a person you don't know that you have simply met through irc
[11:59] <powerkil_> :)
[12:01] <powerkil_> anyone coding in ffmpeg ? can help me ? I have some depreacted function in my patch that need update
[12:16] <cbsrobot> powerkil_: join #ffmpeg-devel for developpement
[12:16] Last message repeated 1 time(s).
[12:16] <cbsrobot> or at least give a hint what goes wrong
[12:17] <cbsrobot> powerkill ^
[12:26] <powerkill> j #ffmpeg-devel
[12:28] <powerkill> url_get_filename is deprecated but I don't know what to use instead
[12:28] <powerkill> I'm trying to port a patch to the last ffmpeg version
[12:34] <durandal_1707> powerkill: use URLContext.filename ?
[12:37] <powerkill> so instead of url_get_filename(post_pb, mov->filename, sizeof(mov->filename)); ?
[12:38] <durandal_1707> url_get_filename is gone in latest version
[12:39] <powerkill> Yes I see I have log of deprecated http://pastebin.com/eskr629y
[12:39] <powerkill> *lot
[12:39] <durandal_1707> what version you are using?
[12:39] <powerkill> 1.1
[12:39] <powerkill> I was using 0.7 and want to use 1.1 now
[12:40] <durandal_1707> the 1.1 do not have it at all
[12:40] <powerkill> So I have to update all the function and it will work right ?
[12:41] <powerkill> I already update url_is_streamed to seekable
[12:42] <powerkill> but url_get_filename url_fileno url_connect put_flush_packet av_metadata_get ... are function that are not available anymore
[12:43] <durandal_1707> can we know for what program you are working on?
[12:43] <powerkill> for outputing smoothstreaming format
[12:45] <powerkill> urlcontext.filename is not a pointer anymore
[12:46] <dott_infernus> hi guys, is there any way to use ffmpeg function in c++
[12:46] <dott_infernus> ??
[12:47] <durandal_1707> powerkil_: there is char * filename in URLContext
[12:48] <gxk> #videolan
[12:48] <gxk> sorry
[12:49] <powerkil_> durandal_1707: can you help me with the error if I send you the code ?
[12:51] <durandal_1707> powerkil_: what error?
[12:52] <powerkil_> http://pastebin.com/H6vRY95W here are all the error
[12:54] <durandal_1707> from where you got ism.c code?
[12:54] <powerkil_> I convert url_is_streamed(s->pb) with !(s->pb->seekable)
[12:56] <powerkil_> from http://smoothstreaming.code-shop.com/
[12:58] <durandal_1707> so you paid for it?
[12:59] <powerkil_> there is a commercial and a open licence
[12:59] <durandal_1707> code can be downloaded?
[12:59] <durandal_1707> for free?
[13:00] <powerkil_> yes http://www.unified-streaming.com/support/documentation/ffmpeg-addon/
[13:00] <powerkil_> just have to register on their site
[13:03] <gxk> need recommendation for arm able to encode 1080p30 with ffmpeg?
[13:13] <simonec77> sorry: what is the correct command line to complile ffmpeg with toolchain msvc and debug support for msvc?
[13:22] <durandal_1707> simonec77: it is in documentation available on ffmpeg.org
[13:44] <b_jonas> simonec77: http://ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b
[14:43] <Eric___> I have one question on HLS standard using ffmpeg. Can we force client to always look for the highest bit rate defined in the manifest file? instead of looking for the lowest bit rate in the manifest file?
[14:53] Last message repeated 1 time(s).
[14:58] <simonec77> durandal_1707: I have followed the documentation at http://ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b but in this nothing is related to building ffmpeg  in toolchian MSVC with the MSVC debug support... to be alble to debug whit MSVC needs: *.lib, *.dll, headers, *.pdb and *.ilk , I'm alble to compile obtaining *.lib, *.dll, headers bu NOT the *.pdb and *.ilk necessary to be able to debuf FFMPEG libraries in
[15:03] <JEEB> pdb is only needed when the symbols are wanted to be outside of the binary itself AFAIK. I would guess an --enable-debug library of ffmpeg would work. Not sure how many symbols the standard configured library has
[15:11] <simonec77> this is my command: ./configure --toolchain=msvc --enable-shared --extra-cflags="-Z7" --extra-ldflags="-DEBUG"
[15:11] <simonec77> it run fine, then I do make
[15:11] <simonec77> and run fine
[15:12] <simonec77> but no *.pdb and no *.ilk in the libraries foledr...
[15:12] <simonec77> these are necessary to be able to debug FFMPEG libraries in MSCV envoronment...
[15:18] <JEEB> I disagree with the ilk file, and pdbs just contain the debug symbols in a separate file instead of the binary itself
[15:18] <JEEB> also ilk files are only done during debug compilation
[15:18] <JEEB> --enable-debug
[15:18] <JEEB> try with that
[16:55] <Pinhole> I have an ts stream with 6 mpeg4 programs in it.  I want to convert it to mpeg2 ts with all 6 programs.   I'm not finding any way to do that.  Any hints?
[18:59] <Pinhole> how do you transcode a mpts with mp4 programs into a mpts with mpeg2 programs?
[19:40] <octavio_> Hi i have a quiestion, when i run ./configure i got a error message and the last line of the config.log is "./configure: /tmp/ffconf.VhP28398.sh: /bin/sh: bad interpreter: Permission denied" please help me
[19:41] <octavio_> i have run .configure as root, and the /bin/sh exists
[19:46] <beastd> octavio_: i can't think of any cases where you should run ./configure as root. so please don't do it.
[19:47] <octavio_> beastd: thank you i will not
[19:48] <beastd> octavio_: i never had this error myself but it sounds like configure has probelems executing the e.g. generated shell script
[19:48] <beastd> maybe it is a problem with your /tmp. you could create a directory in your home and try to use that
[19:49] <octavio_> yes, i have set the enviroment variable TMPDIR in my home dir and this fix the problem, thank you!
[19:49] <octavio_> :)
[19:49] <beastd> octavio_: good! you solved your problem already.
[19:50] <beastd> octavio_: but i guess it is better you use some dedicated temp dir like ~/fftemp or so. it is easier to cleanup if temporary files stay for some reason
[19:52] <octavio_> yeah i see that, ok i will try, thank you so much
[19:56] <AL13N> burek: llogan: the thing is, that with -s 640x480, the resulting video file is 640x422 which is correct. but, the image preview is 640x480, breaking the aspect ratio
[19:56] <AL13N> burek: llogan: and, it's only webm with this issue, mp4 and ogg doesn't have this
[19:57] <AL13N> if i do 640:-1 it will not be the expected result if the source file was rotated and thus had 1080x1920
[20:17] <burek> AL13N, what is your goal?
[20:17] <burek> to scale down the video
[20:17] <burek> or to stretch it to fit 640x480
[20:18] <AL13N> burek: my goal was to convert any video to within 640x480
[20:18] <AL13N> keeping aspect ratio
[20:19] <AL13N> -s did that perfectl
[20:19] <burek> you cannot do that
[20:19] <AL13N> i did mp4, ogg and webm
[20:19] <AL13N> burek: ? what do you mean, i cannot do that?
[20:19] <burek> you can either keep the aspect ratio or to stretch it to 640x480
[20:19] <burek> you can't do both
[20:19] <AL13N> ah
[20:19] <AL13N> not stretch
[20:19] <AL13N> to within 640x480
[20:19] <burek> that's called stretching
[20:19] <AL13N> ie: those are the maximum resolutions
[20:20] <burek> oh
[20:20] <burek> then use 640:-1
[20:20] <burek> or -1:480
[20:20] <burek> depending on which ordinate you want to fix
[20:20] <AL13N> 640x200 is ok and 200x480 is also ok
[20:20] <AL13N> burek: any
[20:21] <burek> well choose one
[20:21] <burek> and then choose the right syntax according to that
[20:21] <AL13N> burek: anyway, i used ffmpeg -i file.MOV -s 640x480 -r 12 file.{MP4|OGG|WEBM}
[20:21] <AL13N> it worked
[20:21] <AL13N> the video keeps aspect ratio and it respects the max resolutions
[20:22] <burek> AL13N, it doesn't work that way
[20:22] <burek> i don't know what's the meaning of your "it worked"
[20:22] <burek> but it's not implemented to work that way
[20:22] <AL13N> burek: the documentation said so
[20:22] <burek> so the correct way to say it is: it shouldn't have worked the way you used it
[20:22] <burek> can you give me a link
[20:22] <AL13N> i'll relook
[20:23] <burek> if you specify both X and Y in -s
[20:23] <burek> it stretches video
[20:23] <burek> to satisfy both of your ordinates
[20:23] <burek> if you put -1 for any of those, it will auto-calculate it, to keep the aspect ratio
[20:23] <AL13N> in any case, it did work, but when i open up dolphin and see the 3 videos, 2 preview images are correct, and the 3rd one (webm) displayed the preview in 640x480 aspect ratio, even though the movie was 640x422
[20:23] <burek> as i said
[20:24] <burek> it didnt work
[20:24] <AL13N> burek: but the problem is that i don't know
[20:24] <burek> period.
[20:24] <burek> what worked is probably a bug
[20:24] <burek> and you shouldn't rely on it
[20:24] <AL13N> i don't know if it's 1920x1080 or 1080x1920
[20:24] <AL13N> so i can't just put -1 on height
[20:24] <burek> can you give me a link to the docs that you've read
[20:24] <burek> so i can check what is says
[20:25] <burek> it*
[20:32] <AL13N> burek: i have a hard time locating it
[20:32] <AL13N> burek: ok, so maybe it's a bug, so what do you propose i use instead?
[20:34] <burek> as suggested, use -1
[20:35] <AL13N> burek: but as i said, if i use 640:-1 and it's 1080x1920, i'll have a height that exceeds 480 by far
[20:35] <burek> then use -1:480
[20:36] <AL13N> burek: but, i don't know in advance the resolution of the source
[20:38] <AL13N> at least the -s work; perhaps one could just transform the bug into a feature and document it...
[20:40] <AL13N> burek: anyway, can you tell me if webm has an included preview image (or any other container) and how to find out if it is?
[20:41] <burek> what is a preview image?
[20:43] <AL13N> well, at least some image formats have an included small image (sort of a thumbnail) so that the image doesn't need to get rendered to get a thumnail. i wonder if any video formats have this feature too
[20:44] <AL13N> i donno if i'm explaining myself well here
[20:45] <AL13N> maybe this more related to the libraries who do the actual video codecs...
[20:45] <klaxa> like metadata thumbnails?
[20:45] <burek> i think i understand, but i dont think any of those do support such thing
[20:45] <AL13N> klaxa: yes, that sounds like what i mean
[20:45] <burek> it is the same anyway, you will have to extract either that thumb or 1 frame from video stream
[20:45] <burek> so basically in both cases you'll have to extract it
[20:46] <AL13N> oh yes, i'm not really asking about that
[20:47] <AL13N> this is more for non-video related programs, that they don't need a video decoder to get a preview/thumbnail
[20:47] <AL13N> i suspected some containers (or video codecs themselves) would be able to do this
[20:47] <klaxa> well but they will need a demuxer
[20:47] <burek> i see.. well try google.. i didnt hear of any so far
[20:47] <AL13N> klaxa: true, maybe
[20:48] <klaxa> you might be able to add it to matroska as an attachment
[20:48] <AL13N> well, i was thinking that maybe HTML5 video tags (from browsers) would be able to show the image while the file is caching/loading
[20:48] <AL13N> if such a thing exists
[20:49] <AL13N> but, if it isn't much heared of here, it'll not really be true
[20:49] <klaxa> doesn't look like attachments are supported in webm
[20:49] <AL13N> anyway: burek, klaxa about that earlier issue, do you know of a solution how i can do what i want for scaling?
[20:50] <klaxa> script it :V
[20:50] <klaxa> and do calculation automatically
[20:50] <AL13N> klaxa: how? i'd need to know the resolutions beforehand?
[20:50] <AL13N> or not?
[20:51] <klaxa> well yeah, if you don't know the orientation beforehand, you can't really predict the resolution you want
[20:51] <AL13N> klaxa: yes...
[20:51] <AL13N> klaxa: so, how would you go about it?
[20:52] <klaxa> maybe ffprobe and parse with grep? actually i think you can use variables within one ffmpeg command
[20:52] <klaxa> referencing input resolution
[20:52] <AL13N> klaxa: it's intended for webview and i have a place of maximum 640x480 to put it
[20:52] <AL13N> klaxa: that sounds interesting
[20:52] <AL13N> klaxa: got any search terms or links for that kind of thing?
[20:52] <klaxa> currently looking at the documentation for that
[20:53] <klaxa> more like looking for it
[20:53] <AL13N> awesome
[20:54] <klaxa> maybe this? http://ffmpeg.org/ffmpeg-scaler.html
[20:54] <klaxa> no idea how to use that though :S
[20:56] <klaxa> uh... probably not...
[20:58] <AL13N> unless i could script with if() and max() and stuff, it doesn't seem likely
[20:59] <burek> AL13N, if you compiled your ffmpeg
[20:59] <burek> you can patch it a little bit
[20:59] <burek> add a single if(width>height) in scale filter
[20:59] <burek> which will determine if -1:480 or 640:-1 should be used
[21:00] <burek> :)
[21:00] <burek> or use ffprobe first to determine which dimension is greater
[21:00] <burek> and based on that use one of those 2 for scale
[21:01] <burek> I've created a feature request, but I can't promise it will be implemented any time soon
[21:01] <burek> https://ffmpeg.org/trac/ffmpeg/ticket/2150
[21:01] <AL13N> actually, i just read that complex filters can use some functions
[21:01] <burek> so, i dunno
[21:01] <burek> if ffmpeg supports some kind of conditional functions/expressions, like IF()
[21:02] <burek> you might do something like: -vf scale=IF(width>height,640:-1,-1:480)
[21:02] <burek> :)
[21:02] <burek> -might +could
[21:02] <burek> but i think it doesnt
[21:03] <burek> hmh
[21:03] <burek> try this
[21:03] <burek> scale=640:-1,scale=-1:480
[21:05] <AL13N> after each other?
[21:05] <burek> yes
[21:05] <AL13N> won't work
[21:06] <AL13N> the second one will upscale again if the video would've been 640x422
[21:06] <burek> try it
[21:07] <AL13N> as i thought: 853x480
[21:08] <burek> ok, so you need OR and not AND
[21:08] <burek> well, it is a problem :)
[22:06] <viric> hm it looks like 'ffmpeg' completely decodes the video stream before the start point, if given "-ss".
[22:08] <viric> Can anything make ffmpeg seek? The input is mkv
[22:09] <klaxa> i'm not sure, i know i knew something at some point, i'll go through my logs
[22:09] <viric> thank you!
[22:09] <llogan> placement of -ss matters.
[22:09] <viric> ahh
[22:09] <klaxa> ah yeah that was it
[22:09] <klaxa> no need to go through my logs :)
[22:09] <viric> before -i!
[22:09] <burek> http://ffmpeg.org/trac/ffmpeg/wiki/Seeking%20with%20FFmpeg
[22:11] <viric> amazing
[22:11] <viric> thank you!
[22:13] <burek> :beer: :)
[22:13] <viric> that wiki helps a lot
[22:13] <viric> (not only for that page. For many others too :)
[22:17] <llogan> a VP8/9/Vorbis/webm guide is probably next in line...not that i use those formats (excluding vorbis)
[22:18] <pzich> would fast seek be a reason for audio seeming to be out of sync (and faster than the video), or should I be looking for another issue?
[22:21] <burek> viric thanks, we do are best, with the free time that we all have
[22:21] <burek> -are +our
[22:21] <viric> llogan: yes, that'd be great
[22:25] <viric> What can this be? [swscaler @ 0x28088e0] Warning: data is not aligned! This can lead to a speedloss
[22:26] <juanmabc> viric: old ffmpeg
[22:26] <viric> mh it's 1.0
[22:26] <juanmabc> mmm, then shouldn't
[22:26] <viric> I'll get 1.1
[22:28] <viric> I'm using yadif,crop as filters
[22:29] <viric> ffmpeg1.1 says the same, but the [swscaler..] appears in blue instead of white :D
[22:30] <juanmabc> haha
[22:30] <beastd> viric: would be a good idea to file a bug report (including full uncut output of a sample commandline triggering the message)
[22:31] <viric> Ok
[22:31] <viric> a trac ticket?
[22:32] <beastd> viric: yes
[22:34] <viric> http://ffmpeg.org/trac/ffmpeg/ticket/2151
[22:36] <beastd> viric: normally you submit the ffmpeg output with higher log level. look here for instructions: http://ffmpeg.org/bugreports.html
[22:36] <viric> oh
[22:37] <beastd> anyway thanks for the report
[22:37] <viric> I can do it
[22:38] <beastd> That would be nice.
[22:39] <viric> done
[22:40] <viric> any idea? it seems it's the crop that does that
[22:40] <``durandal_1707> what is problem?
[22:41] <viric> it tells me about "data is not aligned! This can lead to a speedloss"
[22:41] <``durandal_1707> and ?
[22:41] <viric> juanmabc said it's not normal to have that on a recent ffmpeg
[22:41] <viric> and beastd asked for a ticket about it
[22:46] <``durandal_1707> well you are croping to weird dimension, so it is not bug
[22:47] <viric> ok
[22:47] <viric> I thought os.
[22:47] <viric> so
[22:47] <viric> I tried to use multiples of 16, but it didn't change anything
[22:47] <viric> what is the alignment about?
[22:48] <``durandal_1707> multiplies of 16 for what?
[22:48] <viric> the crop numbers
[22:49] <viric> (question apart... anyone knows how can I delay audio vs video?)
[23:31] <llogan> viric: is it synched correctly if you leave out the yadif filter?
[23:32] <viric> audio-video?
[23:32] <llogan> yes. that is what you were asking about I assume.
[23:32] <viric> well, it's not that ffmpeg desyncs anything
[23:32] <viric> I've an original desynched
[23:32] <llogan> oh
[23:32] <viric> and I wanted to more or less correct it
