[00:07] <derrink> Hi guys, i want to get FFmpeg latest version (1.1) on my CentOS 6.3 Server, i dont want to compile from source, any one keep any repo with precompiled latest ffmpeg for centos 6 ?
[00:08] <klaxa> static builds
[00:09] <derrink> the version in repoforge repo is very old, 0.5.2
[00:12] <viric> anyone running linux + firefox watching html5 videos?
[00:12] <viric> Somehow I think videos play much worse if html5, than in flash.
[00:12] <derrink> what version ffmpeg is the dropbox link?
[00:15] <derrink> and how to install it ?
[00:16] <klaxa> you extract the archive
[00:16] <klaxa> and... well that's it
[00:17] <klaxa> you can move the binary to a directory in your PATH
[00:17] <derrink> oh
[00:17] <viric> W 12
[00:22] <llogan> derrink: or just execute it ./ffmpeg -i ...
[00:23] <derrink> yeah llogan i just added the binary to my PATH
[00:23] <derrink> i didnt realize it was a binary in the package
[00:23] <llogan> just double check that the static version is being used instead of your distro's version
[00:39] <elkng> cant ffmpeg make 3D video into regular one ? I want to convert that video http://thepiratebay.se/torrent/6898884
[00:41] <llogan> lol
[00:41] Action: llogan "deletes this page" from Firefox history
[00:45] <elkng> llogan: so to hide it from your mom ?
[00:45] <elkng> I first thought it was directs cut from original avatar
[01:00] <klaxa> elkng: this video is in red-blue-3D you won't be able to really extract one of the two images
[01:01] <klaxa> if it was saved in seperate video tracks it would have been a different story
[01:05] <elkng> klaxa: yes, there are red and blue colors, and also white at the end, if you know what I mean
[01:05] <klaxa> :D
[01:05] <elkng> I mean credits
[01:05] <klaxa> yeah i saw those
[01:43] <KeshlWare> Is there a magical way to signify in an .mp4 file encoded with h.264 for it /not/ to be played in-frame in a browser? For some reason it just never works and I'd like to force people when I link to an .mp4 to download it and play it locally rather than in the window.
[01:44] <klaxa> i highly doubt it
[01:46] <KeshlWare> Dang. D:
[01:46] <KeshlWare> Why doesn't it work in-frame, then? I've tried it on multiple systems, multiple OS's and browsers, but it just /never/ works. Instant blackscreen.
[01:47] <KeshlWare> Video controls pop up, they sometimes move, sometimes don't, but are always responsive, and the screen's always black.
[01:48] <klaxa> is it html5?
[01:48] <KeshlWare> I compress using a line like:    ffmpeg -r 30 -i pngstream.png -vcodec libx264 -preset medium -crf 18 OUT.mp4
[01:48] <KeshlWare> Dunno. I link directly to the .mp4 file, no HTML inbetween. if therre is any, the browser's adding it.
[01:48] <KeshlWare> *If there
[01:48] <klaxa> maybe, just maybe webm might work better
[01:48] <klaxa> no idea though
[01:48] <KeshlWare> Happens on Chrome, afari and Firefox.
[01:48] <KeshlWare> *Safari
[01:48] <KeshlWare> and Opera.
[01:48] <klaxa> i don't like in-line video stuff
[01:49] <KeshlWare> Neither do I. x.x
[01:49] <drv> you probably need to run qt-faststart or a similar tool on the output file
[01:49] <drv> that moves the index to the front of the file so it's streamable
[01:50] <KeshlWare> Ah.
[01:50] <drv> (qt-faststart is part of ffmpeg)
[01:50] <KeshlWare> ...That'd make a lot of sense. Is this part of ffmpeg or -- Kay good. How's I do, oÉo?
[01:51] <drv> pretty much just 'qt-faststart file.mp4 rewritten-file.mp4'
[01:51] <drv> and then you can delete the original
[01:51] <KeshlWare> "ql-faststart is not recognized as an internal or external command", oÉo
[01:53] <drv> depending on what distro you are using, it might not be installed as part of the package
[01:53] <KeshlWare> I'm on windows. D:
[01:54] <drv> this looks promising http://ffmpeg.zeranoe.com/blog/?p=59
[01:54] <KeshlWare> Squee ^É^
[01:55] <KeshlWare> Dankies, oÉo.
[01:58] <KeshlWare> drv: Nupe, oÉo. Didn't do it.
[01:58] <KeshlWare> http://ompldr.org/vaDRxZA/OUT2.mp4
[02:00] <cbsrobot> KeshlWare: try: ffmpeg -r 30 -i pngstream.png -vcodec libx264 -preset medium -crf 18 -movflags +faststart OUT.mp4
[02:02] <KeshlWare> cbsrobot: Nupe, oÉo. http://ompldr.org/vaDRxZA/OUT2.mp4
[02:02] <KeshlWare> Er
[02:02] <KeshlWare> ...
[02:02] Action: KeshlWare facedesks and uploads the right file.
[02:04] <KeshlWare> Appearntly the site thinks it matches the previous upload.
[02:04] <KeshlWare> Checksum must be identical or something.
[02:04] <cbsrobot> nah
[02:04] <cbsrobot> clean your cache
[02:04] <KeshlWare> Yeah, it's the same.
[02:04] <KeshlWare> Just did md5sum on each.
[02:05] <cbsrobot> hmm what version are you using ?
[02:05] <cbsrobot> ffmpeg version
[02:05] <KeshlWare> N-47062-g26c531c oÉo
[02:06] <KeshlWare> November 25th 2012, some nightly build.
[02:06] <cbsrobot> try to update
[02:06] <drv> hmm, i'm not sure what chrome doesn't like about that file
[02:07] <KeshlWare> Chroime, opera, Firefox and Safari, oÉo.
[02:08] <llogan> drv: there is also "-movflags faststart" so you don't have to use qt-faststart
[02:08] <KeshlWare> Updated to 1.1, different sum..
[02:08] <drv> interesting, that must be fairly recent... guess i missed it
[02:08] <KeshlWare> And smaller output, oÉo.
[02:08] <KeshlWare> Barely but yeah.
[02:09] <KeshlWare> http://ompldr.org/vaDRxaw/OUT4.mp4 Nupe.
[02:09] <llogan> drv: yeah, it is fairly recent. just means you need to get back to some ffmpeg code contributin' to refresh!
[02:09] <drv> if only time grew on trees... ;)
[02:09] <KeshlWare> Trees grow on time, oÉo. That close enough for'ya?
[02:10] <drv> i can't find any obvious way to tell what's going on with the chrome video playback stuff, no obvious output in the dev console or anything
[02:10] <llogan> ah, didn't see that cbsrobot already mentioned movflags
[02:10] <drv> this may be related http://stackoverflow.com/questions/13513621/creating-chrome-compatible-mp4-with-ffmpeg-from-commandline
[02:11] <KeshlWare> Ah, baseline might be it.
[02:11] <KeshlWare> Too bad I can't use that.
[02:12] <cbsrobot> ffmpeg -i OUT2.mov segfaults here!
[02:12] <KeshlWare> .mov? These are .mp4's, oÉo.
[02:13] <cbsrobot> also OUT4.mp4 segfaults
[02:13] <cbsrobot> mov, mp4 its almost the same
[02:13] <KeshlWare> Doesn't segfault here, oÉo.
[02:13] <KeshlWare> Almost, yes, but what if you happen to have OUT2.mov on your hard drive, in the same folder, from someone else? .É.
[02:14] <cbsrobot> KeshlWare: can you pastebin the output of ffmpeg -i OUT4.mp4
[02:14] <KeshlWare> Not easily. Lemme see if I can redirect it, one momeeeent..
[02:14] <KeshlWare> Nope. Not easily. Gimme like ten minutes.
[02:14] <cbsrobot> you can use:  ffmpeg -report -i OUT4.mp4
[02:15] <cbsrobot> it will write a log file
[02:15] <KeshlWare> Says "at least one output file must be spe" ...Oh.
[02:15] <KeshlWare> .... Nope that don't work either.
[02:15] <cbsrobot> doesnt matter
[02:15] <cbsrobot> ah
[02:15] <KeshlWare> Just gimme ten minutes.
[02:15] <cbsrobot> strange
[02:15] <drv> this is my (somewhat outdated) system ffmpeg: http://pastebin.com/SeevWMsS
[02:16] <drv> i presume the issue is the color space based on that stack overflow post
[02:16] <cbsrobot> can you pastebin the followin report: ffmpeg -report -i pngstream.png
[02:16] <KeshlWare> Oh, easuier than I thought: http://pastebin.com/c6Uf4m1F
[02:16] <cbsrobot> what is pngstream btw ?
[02:16] <KeshlWare> Frame_%04d.png
[02:17] <KeshlWare> Nope. Says I gotta supply an output file.
[02:17] <KeshlWare> When I do, it complains it cna't use .txt
[02:17] <cbsrobot> ok
[02:17] <KeshlWare> I figure it wants a movie, which, don't make sense.. <.<
[02:17] <cbsrobot> add -pix_fmt yuv420p
[02:17] <KeshlWare> To where oÉo?
[02:18] <cbsrobot> ffmpeg -r 30 -i Frame_%04d.png -vcodec libx264 -preset medium -crf 18 -movflags faststart -pix_fmt yuv420p OUT9.mp4
[02:19] <KeshlWare> ...oh, the, logs are made.
[02:19] <KeshlWare> Weirdo thingy.
[02:20] <drv> hmm, my just-built git ffmpeg does not crash with ffmpeg -i OUT4.mp4...
[02:20] <KeshlWare> Squee OÉO http://ompldr.org/vaDRxbw/OUT9.mp4
[02:20] <KeshlWare> Choppy cuz buffer but sqyee OÉO
[02:20] <KeshlWare> *squee OÉO
[02:21] <cbsrobot> wut ?
[02:21] <cbsrobot> crf 18 is quite high quality
[02:21] <KeshlWare> Ish happynoise, oÉo.
[02:21] <cbsrobot> use crf 27
[02:22] <KeshlWare> And yes, it is. I'm a bit obsessive.
[02:22] <KeshlWare> I really can see the difference between 18 and 25. It bothers me. >w>
[02:22] <cbsrobot> ok - leave it then
[02:24] <KeshlWare> Now, I'm crazy and have more RAM than any sane person needs. Is there a magical way to preload all the uncompressed .png's into RAM and then try each preset, oÉo? Sometimes medium compresses better than placebo, for example. (I also have more time than any sane person, and more processing power. <.< Plus the videos are short.)
[02:24] <llogan> KeshlWare: generally you want to use the highest crf value that still gives and acceptable quality.
[02:24] <llogan> *an acceptable...
[02:25] <llogan> placebo is a joke and a waste of time
[02:25] <KeshlWare> I know it only gives like a 2% return over veryslow, but 2% is 2%.
[02:25] <llogan> less than that
[02:25] <KeshlWare> I use Luxrender for serious stuff. Believe me, I obsess over anything greater than .0001%.
[02:27] <KeshlWare> And when I use pngcrush, I use -brute. <.<
[02:34] <cbsrobot> drv: mine still segfaults
[02:34] <drv> hmm, got a backtrace? maybe i am just lucky
[02:36] <cbsrobot> http://pastebin.com/07WvJytT
[02:36] <cbsrobot> drv: ^
[02:37] <drv> ah, i am building on linux with gcc, maybe it is some corner case that only gets tickled with llvm
[02:37] <drv> (or llvm optimization bug)
[02:37] <cbsrobot> maybe - I'll file a bug
[02:41] <KeshlWare> Just outta curiousity, what are the different settings the presets adjust?
[02:42] <cbsrobot> how hard the encoder should try to encode
[02:43] <KeshlWare> Well, I figured that. XD But I mean, what exactly do they pass? I know they've just got a list of different paramaters, and I wanna know what those are.
[02:43] <cbsrobot> !x264
[02:43] <KeshlWare> I confus. .É.
[02:44] <cbsrobot> KeshlWare: see http://mewiki.project357.com/wiki/X264_Settings
[02:44] <KeshlWare> oÉo.
[02:44] <KeshlWare> Dankies ^É^
[02:47] <llogan> KeshlWare: also see "x264 --fullhelp"
[02:47] <llogan> and the console output will show you what settings are being used
[02:47] <llogan> or: strings input.mp4 | grep x264
[02:49] <cbsrobot> llogan: can you please test http://ompldr.org/vaDRxaw/OUT4.mp4 ?
[02:49] <cbsrobot> just ffmpeg -i OUT4.mp4
[02:49] <cbsrobot> thanks burek
[02:49] <burek> :beer:
[02:50] <KeshlWare> llogan: I don't have x264.exe, oÉo.
[02:54] <burek> http://pastebin.com/RDKYQUq3
[02:54] <drv> x264 --fullhelp has all the details  http://pastebin.com/YcbviuEc
[02:55] <burek> i think he's on win :)
[03:01] <KeshlWare> I said I'm on windows1 D: Anyway danks, was about to say the wikipage doens't got what I need. <É<
[03:15] <llogan> cbsrobot: sorry, endless stream of people in my office. works for me.
[03:16] <cbsrobot> np
[03:16] <cbsrobot> I filed a bug already
[03:16] <cbsrobot> thanks anyhow
[08:32] <sloof> I'm trying to apply a URL watermark to a video. I'm using a transparent PNG.  Right now it's just size 14 bold Arial text.  It looks awful when encoded into an otherwise nice looking 1080p video.
[08:33] <sloof> Is there a guideline to watermark text font type/size etc so the watermark is legible.  It looks like terrible aliasing around the font.
[09:35] <p1r473> hey guys, im having some trouble decoding an h264, the output is just gray video
[09:35] <p1r473> my decoder is set to libva and it plays fine in vlc
[09:44] <relaxed> p1r473: You're using ffmpeg?
[09:47] <p1r473> oh I think it uses hcenc or something
[09:47] <p1r473> but maybe you still know the answer even if this is a ffmpeg room
[09:47] <relaxed> I have no idea what you're doing.
[09:48] <p1r473> im burning a mkv to a dvd using avstodvd but the video encoding of the h264 is coming out as gray
[09:48] <p1r473> even though i can watch it in vlc, and my ffdshow is set to use libvacodec
[09:50] <relaxed> Sorry, no idea.
[09:51] <xiphmont> aaaand looks like mpegts is completely borked.  Damn.
[09:53] <Mavrik> it isn't?
[09:55] <xiphmont> what isn't?
[10:39] <xiphmont> hm.  seeking in ffplay works.  older code doesn't.  Something must have shifted.  OK, n/m, more testing...
[10:40] <durandal_1707> seeking on what?
[10:52] <brx_> how do i create a 5 second mp4 video from a single jpg (no audio required)
[10:56] <relaxed> brx_: -loop 1 -i blah.jpg -t 5
[11:00] <brx_> thanks relaxed
[15:07] <Hfuy> Hello.
[15:07] <Hfuy> The ProRes encoder seems to give me files which are many tens of percent bigger than the Quicktime encoder on the same material with the same requested profile; is this normal?
[15:37] <brontosaurusrex> getting "buffer queue owerflow" with certain input videos (trying to overlay a logo), full -report is here http://pastebin.com/7UhVuHAA , clues?
[15:45] <cbsrobot> Hfuy: at least there is no chromashift !
[15:50] <brontosaurusrex> i mean, does this look like : borken filter or wrong usage on my part, or ...? (Could a fresh git compile solve this?)
[15:57] <brontosaurusrex> can i increase the internal buffer somehow? should i? how?
[16:00] <brontosaurusrex> hrm, if i do an prores intermediate, everything is fine
[16:04] <zmode> hi. is it possible to use `-vf "ass=file.ass` with a stream instead of a file? (something like `-vf "ass=#0:2"`) i'd like to not have to extract the subtitles before streaming my video
[16:28] <cbsrobot> zmode: mkv ? afaik atm not.
[16:29] <cbsrobot> but extracting subtitles is cheap
[16:30] <zmode> cbsrobot: yup, mkv. thank you.
[16:31] <brontosaurusrex> cbsrobot: any clues about that buffer owerflow?
[16:35] <cbsrobot> brontosaurusrex: no - but try to find the smallest command line that triggers the buffer overflow
[16:36] <brontosaurusrex> ok
[16:39] <brontosaurusrex> seems to be anything with -filter_complex
[16:48] <brontosaurusrex> ill try to do a fresh git compile of ffmpeg ....
[17:32] <brontosaurusrex> well, no, fresh git did not help
[17:36] <brontosaurusrex> ehm, what would be a good intermediate format? (prores is slow)
[17:36] <brontosaurusrex> something lossless perhaps?
[17:36] <cbsrobot> utvideo ?
[17:37] <brontosaurusrex> is it fast?
[17:37] <cbsrobot> try it
[17:37] <brontosaurusrex> ok
[17:37] <cbsrobot> or you could try to pipe it
[17:37] <cbsrobot> with yuv4mpeg
[17:37] <brontosaurusrex> an example?
[17:38] <brontosaurusrex> pipe should be must faster right?
[17:38] <cbsrobot> hmm I never remember the bot commands
[17:38] <cbsrobot> ah so
[17:39] <cbsrobot> hehe
[17:39] <cbsrobot> so
[17:39] <cbsrobot> no
[17:39] <cbsrobot> damn it
[17:40] <durandal_1707> lol
[17:40] Action: durandal_1707 kicks ffloger
[17:40] <cbsrobot> burek - I give you a 6pack beer if you fix that ...
[17:41] <cbsrobot> he should also add a command how the bot can send him an email when he's not online ....
[17:42] <cbsrobot> btw. durandal_1707 you still have something to do ?
[17:43] <cbsrobot> I had another idea what you could if you have time ;-)
[17:48] <brontosaurusrex> so the 2nd ffmpeg would just be: ffmpeg -i - or ... ?
[17:49] <brontosaurusrex> well, seems to be working
[17:50] <cbsrobot> yes
[17:50] <brontosaurusrex> damn cool
[17:50] <cbsrobot> brontosaurusrex: please fiel a bugreport
[17:51] <cbsrobot> btw if you use -strict -1 or similar you can also use -pix_fmt yuv444p10 and several others for the yuv4mpeg format
[17:51] <brontosaurusrex> does it matter if input is 420p8 ?
[17:52] <cbsrobot> no - just saying
[17:52] <brontosaurusrex> ok
[17:57] <AL13N> i cannot find any documentation regarding the possible expressions used by ffmpeg in filters. is there a doc regarding this? furthermore, it seems a simple "if(1\,640\,-1)" doesn't work, do i need to set some option to enable expressions in ./configure?
[17:58] <cbsrobot> AL13N: http://ffmpeg.org/ffmpeg-utils.html#Expression-Evaluation
[18:07] <Orphis_> Is there any up to date tutorial I could use to decode some audio data using ffmpeg APIs in C ?
[18:08] <Orphis_> There's of course http://dranger.com/ffmpeg/tutorial01.html but it's a bit old
[18:09] <Mavrik> Orphis_: "doc/examples" subfolder in ffmpeg source has up-to-date examples
[18:09] <Mavrik> for demuxing and decoding
[18:09] <Orphis_> Oh, great
[18:09] <Orphis_> That's too obvious to be found :P
[18:10] <cbsrobot> let's hide it then
[18:23] <Orphis_> What would be the best strategy with the current protocols in ffmpeg to read a non seekable buffer that is managed externally to decode some mp3 data ?
[18:24] <Orphis_> The data is fed to my application by some external code and it fills a buffer that I'd like ffmpeg to decode
[18:24] <Orphis_> A pipe would be nice, but it's supposed to work on some non Unix platforms too
[18:25] <Orphis_> Then, I could use tcp, but isn't that a bit overkill?
[18:25] <Mavrik> Orphis_: check the AVIO functions
[18:25] <Mavrik> create your own AVIO context and pass pointers to functions in it (check doxygen for what do you need)
[18:25] <Mavrik> ffmpeg will call you when it requires data
[18:26] <Orphis_> Alright
[18:26] <Mavrik> and you'll feed it to its buffer
[18:26] <Mavrik> Orphis_: http://ffmpeg.org/doxygen/trunk/avio_8h.html#a853f5149136a27ffba3207d8520172a5
[18:26] <Mavrik> define your own "read_packet" function
[18:26] <Mavrik> fill the passed buffer with data when it gets called and return number of bytes filled
[18:27] <Mavrik> when just do what the examples do for decode :)
[18:27] <Orphis_> That's easy enough
[18:50] <raket> is it possible to generate a ffserver.conf based on ffmpeg -i file.avi?
[19:09] <maxlapshin> Hi. Can anybody help me with libavcodec/libavformat usage. I transcode mpeg2 to H.264 and get h264 frames delayed. Thus I need to sync audio and video.  I try to write them with av_interleaved_write_frame and I thought that it has internal sync queue, but it refuses to accept non-monotonic timestamps
[19:09] <maxlapshin> what is the right way to sync audio and video dts (I need to add constant delay to audio)? Do I need to write my own queue?
[19:15] <Mavrik> um
[19:15] <Mavrik> av_interleaved_write_frame DOES have a queue
[19:15] <Mavrik> however no muxer will accept non-monotonic timestamps
[19:15] <Mavrik> you just need to make sure your PTS/DTS values always increase
[19:17] <maxlapshin> Mavrik: video PTS cannot always increase because of b-frames
[19:17] <Mavrik> point there
[19:17] <maxlapshin> yet audio is increasing and video is increasing
[19:17] <maxlapshin> I'll pastebin now, one moment
[19:19] <maxlapshin> http://pastebin.com/DGcNav28
[19:20] <Mavrik> ah I see
[19:20] <maxlapshin> https://github.com/erlyvideo/flussonic/blob/0b2751626e61b800bfe3eff0d3eeba4012eae492/apps/ffmpeg/c_src/mpeg2coder.c
[19:20] <maxlapshin> and this is source code
[19:21] <Mavrik> that's a rather huge difference in PTS
[19:21] <maxlapshin> this PTS is in 90000 base
[19:21] <Mavrik> I guess you'll have to manually reorder them before muxing :\
[19:21] <maxlapshin> it is not milliseconds
[19:21] <Mavrik> I know, but that's still a second of difference
[19:21] <maxlapshin> Maybe I'm doing it wrong?
[19:21] <raket> where can i get all the ffpreset files for baseline etc?
[19:21] <maxlapshin> more than second, about 1.5 seconds
[19:22] <maxlapshin> but how can it be a problem if libx264 can give up to 5 seconds delay?
[19:22] <Mavrik> raket: uhm... those are obsolete
[19:22] <maxlapshin> how ffmpeg is working?
[19:22] <Mavrik> raket: what are you trying to achieve
[19:22] <raket> Mavrik: well. i need the baseline preset so i can stream rtsp to my old phone :-)
[19:23] <Mavrik> raket: baseline is a profile, presets (if you're using libx264) are "slow, medium, fast" etc. and set encoding speed
[19:23] <Mavrik> raket: so just do "-profile baseline" and you'll get proper output :)
[19:23] <Mavrik> maxlapshin: 5 seconds delay? huh?
[19:24] <Mavrik> maxlapshin: MPEG-TS container requires increasing DTS it seems
[19:24] <Mavrik> so you'll have to reorder packets when muxing by DTS
[19:24] <raket> Mavrik: what should it be in ffserver.conf? AVProfile baseline?
[19:25] <maxlapshin> Heh. It's a pity =) So I need separate queue for each output stream
[19:25] <maxlapshin> I'm writing multibitrate live transcoder
[19:26] <Mavrik> raket: try "AVOptionVideo profile baseline"
[19:44] <raket> Mavrik: haha ultra error there :(
[20:23] <durandal_1707> cbsrobot: ?
[21:31] <brontosaurusrex> raket,bitrate based would look like:  -vcodec libx264 -b:v number -preset slow -profile baseline -threads 0
[21:31] <brontosaurusrex> and profiles are bitrate and video-size/framerate related as well
[21:33] <brontosaurusrex> or maybe not and i mixed that with levels, in any case its cool
[21:34] <llogan> brontosaurusrex: -profile:v
[21:34] <brontosaurusrex> right
[21:35] <brontosaurusrex> how would i artistically calculate logo size overlay, if video input can be of any size?
[21:36] <brontosaurusrex> i need to slap a logo in a bottom corner
[21:36] <sacarasc> Do it as a percent of the main video?
[21:36] <brontosaurusrex> just taking some percentage of width seems pretty cool so far, but ...
[21:37] <Mavrik> brontosaurusrex: why don't you just scale image first and then slap logo on it? :)
[21:37] <brontosaurusrex> sacarasc: yeah, should i include height percentage as well?
[21:38] <sacarasc> I probably wouldn't...
[21:38] <brontosaurusrex> Mavrik: examples: a. input video is 400*300, b. input video is 1920x1080 and so on
[21:38] <sacarasc> It would skew it.
[21:38] <Mavrik> yeah, but is your output video also arbitrary?
[21:38] <brontosaurusrex> yeah, output should be the same size as input
[21:38] <brontosaurusrex> but this will only work until some certain size i guess
[21:39] <brontosaurusrex> probably i should upscale everything smaller than 1280*720 to just that
[21:40] <brontosaurusrex> well, its a kinda silly idea anyway > i mean to hardcode the video, no beauty can be expected
[21:40] <brontosaurusrex> the logo even*
[21:52] <llogan> just give it 15 pixels padding. done. lazy.
[21:53] <brontosaurusrex> allready done in logo itself, even lazier
[21:58] <brontosaurusrex> sacarasc>	It would skew it. < nah, i mean to take cubic proportion of how much space it would take, scaling would still be proportional
[21:58] <brontosaurusrex> anyway, have enough for today
[22:50] <Orphis_> Just curious: is there any buildscript for ffmpeg using cmake?
[23:55] Action: llogan hits 50% in 85 hour encode session
