[00:19] <cbsrobot> Maverick|MSG: sorry i was afk
[00:19] <Maverick|MSG> np
[00:19] <Maverick|MSG> I'm probably going to wind up trying it either tomorrow or the next day
[00:19] <Maverick|MSG> just wanted to try to code proactively
[00:19] <Maverick|MSG> whatever *that* is
[00:22] <cbsrobot>  if I remember correctly the -to option will be convertet to the duration from the starting point, maybe if you set the -ss before the input (which should print a info iirc to put it after the -i, beacuase you could have multiple -i) that changes the starttime
[00:49] <MorehouseJ09> what are your thoughts on the "Warning: data is not aligned! This can lead to a speedloss" warning when using sws_scale?
[00:49] <MorehouseJ09> looked this up online and found that most people said to ignore it
[00:50] <llogan> it's only a warning, not an error
[00:50] <MorehouseJ09> should I worry about it? Is this a video by video thing or should I go back and peak through my code to see whats up?
[00:52] <llogan> i'm not sure how much of a potential speedloss there could be
[00:54] <MorehouseJ09> llogan: I'm only seeing it once, not for every frame as well so I don't think its anything to worry about for now ...
[05:12] <buu> Why the heck does ffprobe print to stderr?
[05:13] <buu> haha https://trac.ffmpeg.org/ticket/2226
[05:16] <buu> And should I ask why -print_format json; doesn't actually work?
[05:58] <lvella> can I speedup a video just by remuxing it?
[05:58] <lvella> I have an mkv of 2:05 duration, but I want it to be just 2:00, can I speed it up a little?
[05:58] <sacarasc> I think you can change frame rate in the container, but I am not 100% sure.
[05:59] <lvella> wouldn't that mess with the audio/video sync?
[06:04] <theholyduck> lvella, easiest is just to cut 5 secs
[06:04] <theholyduck> :P
[06:04] <theholyduck> speeding up is theoreticcally possible, but a bit annoying
[06:05] <theholyduck> lvella, and no, you cant speed up the audio by remuxing
[06:05] <theholyduck> you can CUT the video
[06:05] <theholyduck> by remuxing
[06:05] <theholyduck> mkverge lets you do a lossless cut
[06:12] <lvella> ok, the audio is flac, it supports (almost) any arbitrary sampling rate
[06:13] <lvella> so, how can I increase the sampling rate a little bit (without actually resampling) so it will be a little faster?
[09:16] <MorehouseJ09> hmm... I'm having trouble with a bus error.
[09:16] <MorehouseJ09> I successfully build a packet and write it with av_interleaved_write_frame -- which returns 0
[09:16] <MorehouseJ09> but afterwards, when I call the write_trailer() method, I get a bus error.
[09:17] <MorehouseJ09> when av_interleaved_write_frame returns 0, shouldn't the packet already have been written to the file?
[10:26] <Apic> A wonderful splendid Prickle-Prickle Morning (UGT) to you all.
[11:46] <burek> hi, is it possible to specify the source udp port for the rtp output, something like: ffmpeg -i ... -f rtp rtp://1.2.3.4:5678?localport=7777
[11:58] <allengreen> a naive question? can linux's signal nested? I mean if  I am a signal handler, and in the handler, I write a access violation code, what would happen?
[12:05] <Lanser> I'd like to use ffmpeg to convert a mp4/flv file into VOB.
[12:06] <Lanser> How can I do it?
[12:21] <relaxed> Lanser: ffmpeg -i input -target ntsc-dvd -q:v 3 -f vob output.vob
[12:22] <Lanser> thank you, relaxed. may god bless your girlfriend with boobs.
[12:22] <Lanser> big boobs, ofc.
[12:22] <Lanser> but I am a lil confused.
[12:22] <Lanser> what is this parameter?
[12:22] <Lanser> -q:v 3 -f
[12:23] <JEEB> -q:v sets the video quantizer
[12:23] <JEEB> -f sets the output container format
[12:23] <JEEB> (usually auto-set with the file name)
[12:24] <JEEB> the target should already set bit rate and maxrate/bufsize so the -q:v is not 100% needed, just you overriding the rate control with another type :)
[12:24] <JEEB> and because relaxed has no way of knowing which type of a DVD you want, he set the ntsc- prefix
[12:24] <JEEB> instead of telling you to read the fine documentation and picking one ;)
[12:25] <Lanser> what is a video quantizer, sir JEEB?
[12:25] <Lanser> and -f?
[12:25] <JEEB> already explained that :P Also written in the fine documentation
[12:26] <Lanser> I want to start converting a video from 05:31 instead from the start.
[12:26] <Lanser> is this possible?
[12:26] <JEEB> quantizer basically sets the compression level (higher quantizer means the pictures are compressed more)
[12:26] <relaxed> it's time to rtfm
[12:26] <JEEB> indeed
[12:26] <JEEB> :)
[12:26] <Lanser> <Lanser> I want to start converting a video from 05:31 instead from the start.
[12:26] <Lanser> <Lanser> is this possible?
[12:26] <Lanser> JEEB?
[12:27] <JEEB> http://ffmpeg.org/ffmpeg-all.html
[12:27] <Lanser> but IS THIS POSSIBLE, jeeb?
[12:27] <Lanser> that's my question.
[12:27] <Lanser> is this possible?
[12:27] <JEEB> I wouldn't be pushing you towards the documentation otherwise, would I :P
[12:27] <Lanser> I don't wanna read all that.
[12:27] <Lanser> it'd take me an hour.
[12:28] <Lanser> just give me the page link
[12:28] <Lanser> which gives me the parameter or something else, to start converting a video from 05:31
[12:28] <Lanser> instead of 00:00
[12:28] <Lanser> that'd be appreciated :-)
[12:29] <JEEB> hint: 5.4, Main options
[12:30] <Lanser> Is there any addon for Firefox which can put 2 downloads in a queue? when one download is complete, move to another instead of staying paused?
[12:30] <Lanser> -t?
[12:31] <JEEB> actual reading is recommended
[12:31] <Lanser> is it the -t parameter, JEEB?
[12:31] <Lanser> IS IT?!
[12:31] <JEEB> lol
[12:31] <Lanser> lol
[12:32] <JEEB> you're an ass, unfortunately. And you seriously should know if that option is correct or not by reading the goddamn explanation of the option after the option :P
[13:17] <burek> just to ask again in case someone knows: is it possible to specify the source udp port for the rtp output, something like: ffmpeg -i ... -f rtp rtp://1.2.3.4:5678?localport=7777
[13:25] <buu> So
[13:27] <buu> Why does ffprobe print to stderr? How do you change that? Why does this guy think it prints to stdout: https://trac.ffmpeg.org/ticket/2226? And why doesn't -print_format work for ffprobe?
[13:29] <buu> Oh and how do I get a text file output of the subtitles from a stream?
[13:32] <saste> buu: you are confused
[13:33] <saste> about text file you should write to a subtitles file (which is plain text)
[13:41] <buu> saste: Confused about what?
[13:41] <bouba> hi all, do you consider jpeg2000 or png as lossless codecs for thumb extracting plz ? (with -qscale:v 1 )
[13:42] <buu> saste: You mean I just need to say output.srt and I get text?
[13:44] <buu> Oh.
[13:44] <buu> How interesting.
[13:44] <buu> I still wish it printed to stdout though.
[13:45] <buu> Or json worked
[13:57] <buu> saste: http://scsys.co.uk:8002/272029
[13:58] <saste> buu: yes, what do you want to print?
[13:58] <saste> ffprobe -h
[13:58] <buu> saste: I want the metadata and the chapter information?
[13:59] <saste> buu: did you grep the manual?
[13:59] <saste> you can do that
[13:59] <buu> I've read the manual repeatedly
[14:00] <buu> does it mention stdout someplace?
[14:09] <matthias1> morning, i have one question: I'm compressing my avi file, but the fps is getting lower every time: frame= 8312 !fps= 39! q=-1.0 size= 6795533kB time=332.81 bitrate=167268.2kbits/s is this a problem?
[14:10] <matthias1> at the beginning it was at about 45 and now it is at 15
[14:10] <buu> Also -pretty doesn't seem to change the output
[14:11] <buu> matthias1: You're referring to fps during compression yes? That presumably just means its doing more work..
[14:11] <buu> per frame
[14:17] <buu> Oh wtf
[14:19] <buu> -show_chapters does something completely different HOW DOES THAT MAKE SENSE
[14:24] <buu> Well, that gets bonus points for being massively confusing but it does work now
[15:06] <matthias1> buu: Thanks!
[15:21] <kode54> is it a bad idea in general to bundle a subset of FFMPEG with a project? I find it more convenient than packaging the entirety of the library and using the build scripts
[15:21] <Apic> Does not sound bad to me.
[15:21] <Apic> MPlayer did that too. ^>^
[15:21] <kode54> and since it's GPL, anyone can rebuild the whole project from scratch anyway
[15:22] <kode54> I suppose I am missing out on the benefits of using the assembly bits, though
[15:22] <kode54> I'll have to figure out a way to bundle a fat binary version of yasm with the repository and set the FFMPEG project to use that for .asm files
[15:23] <kode54> or maybe just 64 bit binary, doesn't matter
[15:23] <Apic> Still does not sound bad.
[15:23] <kode54> depends on if the asm files are even designed to target 64 bit output
[15:23] <kode54> ah
[15:23] <kode54> are any of the .asm files designed for 64 bit output?
[15:24] <kode54> I'll have to look, actually
[15:26] <JEEBsv> < Apic> MPlayer did that too. ^>^ <- trying to copy the incestious relationship of ffmpeg and mplayer is _NOT_ a good idea
[15:26] <Apic> ;-)
[15:26] <kode54> heh
[15:26] <Apic> True.
[15:27] <JEEBsv> that said, no-one says that you may not have a git submodule of a certain known-to-work revision of ffmpeg in a directory of your git repository
[15:27] <JEEBsv> that may be used if so wished
[15:27] <kode54> kind of hard to have a git submodule in a mercurial repository
[15:27] <JEEBsv> actually that's quite possible
[15:28] <kode54> oh? hmm
[15:28] <JEEBsv> just make sure you use the ffmpeg compilation system for ffmpeg, and to use --prefix to install the compiled binaries and headrs
[15:28] <JEEBsv> *headers
[15:28] <JEEBsv> and thus only use things you are supposed to use
[15:29] <kode54> ah
[15:30] <JEEBsv> or you could have a separate projectname-build repo
[15:30] <JEEBsv> for simplified compilation
[15:30] <JEEBsv> like mplayer2 and mpv have
[15:30] <kode54> this is a Mac OS X audio player, and currently, I'm using a Framework project to compile the whole thing into a single dylib type object inside of a .framework bundle, which gets bundled inside a PlugIn's Frameworks directory. the Plugin .bundle gets bundled in the app's PlugIns folder
[15:30] <matthias1> how can i extract only the video, without the audio from an avi file. my avi file is over 100gb big, but i do not want to lose quality
[15:30] <kode54> use the -map switch to select just the video stream, and use -vcodec copy
[15:31] <kode54> ie. if it's stream 0, you'd -map 0:0 -vcodec copy
[15:31] <JEEBsv> you could just do -an or -vn depending on which you don't have
[15:31] <JEEBsv> uhh
[15:31] <kode54> at least that's what I remember
[15:31] <JEEBsv> s/have/want/
[15:31] <JEEBsv> (audio/video none)
[15:31] <kode54> oh, audio/video none switches, neat
[15:32] <kode54> map is required for some of the stuff I end up doing, though
[15:32] <JEEBsv> yes, if you have multiple streams of the type then yes
[15:32] <kode54> namely, remuxing mp4 video files to mkv
[15:32] <kode54> since ffmpeg doesn't seem to support iTunes subpicture streams
[15:32] <JEEBsv> oh, and there's -sn as well for subtitles
[15:32] <kode54> ah, sn
[15:33] <kode54> also I was using -map_metadata -1
[15:33] <JEEBsv> yup
[15:33] <kode54> because I was committing the grave sin of redistributing my iTunes store purchases to select friends
[15:33] <kode54> you didn't hear that just now
[15:34] <kode54> I love the Requiem author's reasoning for abandoning the project
[15:34] <kode54> "my child is getting just old enough to become curious about what I do on the computer, but not old enough to understand the subtle nuances of civil disobedience"
[15:35] <kode54> I mostly only unprotect my videos so I can freely use them with other players, like MPlayerX
[15:36] <kode54> I have yet to be motivated to copy them over to my PS3
[15:36] <kode54> I don't think anyone else who uses the PS3 wants to watch my pony purchases
[15:37] <kode54> nope, I'm not a brony, I just watch a cartoon series which is mildy amusing at times
[15:38] <kode54> does the build system support producing Mac OS Frameworks out of the dylib/headers?
[15:38] <kode54> probably little more than just assembling the dylib without an extension and the headers under a directory structure, along with an Info.plist file somewhere
[15:39] <Benjojo> Good afternoon there, I am trying to compile a timelapse from images, I however made the images filenames unix timestamps. How can I get FFMpeg to read them with those names?
[15:44] <Benjojo> Is it possible to do that?
[15:48] <Apic> Nothing is true, everything is permissible.
[15:48] <brontosaurusrex> Benjojo, not directly the last time i tryed
[15:49] <Benjojo> brontosaurusrex: Oh dear. Looks like I'm going to have to try and change my image capture program!
[15:49] <brontosaurusrex> Benjojo, what i did at the end is a script that makes temporary symlinks to my images with names that ffmpeg would support and then load this into ffmpeg ...
[15:49] <Benjojo> brontosaurusrex: Do you happen to have that script on you?
[15:49] <brontosaurusrex> I can find it, its bash
[15:50] <Benjojo> brontosaurusrex: that would be great!
[15:50] <brontosaurusrex> hold on ...
[15:53] <brontosaurusrex> http://paste.debian.net/58351/ (probably interesting only from line 100 and on ) Benjojo
[15:54] <brontosaurusrex> p.s. Only tested on OSX
[16:14] <Benjojo> Thanks brontosaurusrex
[16:18] <Apic> http://narf-archive.com/pix/f3366f6478d922273f64db94543488bd659802b4.jpeg
[16:20] <durandal_1707> ;)
[16:25] <Apic> =)
[17:05] <Apic> http://bash.org/?4281
[17:05] <Apic> ww
[17:14] <bouba> hello, some guru knows a better param than "-vf fps=fps=1/10" to extract thumbnails each 10sec ? it seems like ffmpeg drops frames to keep CFR
[17:14] <bouba> plz
[18:10] <brontosaurusrex> bouba, what is the input codec/stream type?
[18:10] <bouba> brontosaurusrex>, h264
[18:11] <brontosaurusrex> ok, and this are huge/longer files?
[18:11] <brontosaurusrex> also what is the needed thumbnail resolution?
[18:12] <bouba> huge files give me a better precision than small ones
[18:12] <bouba> resolution : 2048x1024
[18:13] <bouba> but the input is not 25fps
[18:13] <bouba> more like 24,98...
[18:13] <brontosaurusrex> ok, so you need thumbnails at 2048x1024 px resolution?
[18:13] <bouba> yeah
[18:13] <bouba> i tried various methods
[18:14] <bouba> -r 1/10
[18:14] <bouba> -vf fps=fps=1/10
[18:14] <bouba> http://ffmpeg.org/trac/ffmpeg/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video
[18:15] <bouba> i also specified a lossless output with "-qscale:v 1"
[18:15] <brontosaurusrex> ok, how about converting your input stream to something I frames only, like prores and then going for the fps=1/10
[18:16] <bouba> sorry, "something I frames only"...I-frame ?
[18:16] <bouba> never used that
[18:17] <bouba> brontosaurusrex, do you have a link/method for me please ?
[18:18] <brontosaurusrex> http://en.wikipedia.org/wiki/Video_compression_picture_types#Intra_coded_frames.2Fslices_.28I.E2.80.91frames.2Fslices_or_Key_frames.29
[18:19] <brontosaurusrex> Like i said i would try your method fps=1/10 method, but would do a temporary prores intermediate and then feed that
[18:20] <bouba> thx, i'll try
[20:01] <buu> So if I use -codec libmp3lame, why does the output say     encoder         : Lavf55.19.102
[20:01] <JEEBsv> because that's the muxer
[20:03] <buu> oh
[20:03] <buu> How about major_brand     : mp42 ?
[20:04] <JEEBsv> that's part of the "mp4" format itself
[20:04] <JEEBsv> the brand as which the file is supposed to be read as
[20:04] <JEEBsv> there can be multiple if the file fits under multiple specifications
[22:46] <ac_slater> Hey guys, this isnt an ffmpeg issue but I think someone in here will be able to help me. I'm interested in taking RAW image data from a camera sensor and creating an RTSP stream. Does anyone know a library capable of this? (assume linux)
[22:46] <ac_slater> (and I use RAW and RGB camera data.... kind of unimportant, but a detail)
[22:49] <ac_slater> And I dont ever have a video container, I want to pipe the raw data into an RTSP pipeline of sorts. Anyway I'll stop flooding the channel. Any help/advice is appreciated.
[22:58] <llogan> ac_slater: http://ffmpeg.org/ffmpeg-protocols.html#rtsp
[22:59] <ac_slater> llogan: right. I'm looking for some development tools though.
[23:00] <ac_slater> Maybe I should be on #ffmpeg-dev
[23:00] <llogan> that's for development of FFmpeg and patch discussion
[23:01] <llogan> (and it's #ffmpeg-devel)
[23:03] <ac_slater> llogan: ah right.I must have misunderstood. It looks like the link you sent me was just a list of protocols ffmpeg can support.
[23:03] <ac_slater> Are there APIs (and libraries) for these things (libavformat?)
[23:04] <llogan> oh, the libraries. might find something useful in doc/examples
[23:04] <llogan> or you ask on libav-user mailing list: http://ffmpeg.org/mailman/admindb/libav-user
[23:05] <ac_slater> llogan: this is perfect. For some reason I didnt even think to actually look at libavformat. I'm new to RTSP so this should be interesting
[23:05] <ac_slater> llogan: thanks for the advice.
[23:06] <llogan> i have no experience with API usage, so I can't give you much more info
[23:06] <ac_slater> it's ok, you'd helped a bunch. Thanks.
[23:06] <ac_slater> you've *
[23:16] <kode54> another of my peeves is that the switches for specifying start/end positions for selecting a range of an input are in timestamps
[23:16] <kode54> there were times when I wanted to chop videos on exact frames
[23:17] <kode54> I would be transcoding anyway, since the original would be in some weak compression that was fast enough for my capture machine to pull a full 60fps
[23:18] <kode54> superdump: ahoy thar
[23:19] <llogan> kode54: did you see if the select filter can do what you want?
[23:19] <kode54> I hadn't
[23:20] <llogan> select="gte(n,1234)" or something like that
[23:20] <kode54> I should try that if I ever need to do some chopping
[23:20] <llogan> http://ffmpeg.org/ffmpeg-filters.html#select_002c-aselect
[23:25] <superdump> hello kode54
[23:25] <superdump> did you used to hang around foobar2000-related channels?
[23:25] <kode54> still do
[23:25] <superdump> and hydrogenaudio?
[23:26] <superdump> :)
[23:26] <kode54> and there
[23:26] <superdump> good good, my memory works
[23:26] <superdump> how goes it?
[23:26] <kode54> just fine
[23:26] <superdump> good good
[23:26] <kode54> saw Gravity yesterday, man was that a ride
[23:27] <superdump> cool :)
[23:28] <kode54> also forked a Mac player called Cog a couple of weeks ago and have pushed over 150 commits to it
[23:28] <superdump> why forked
[23:28] <kode54> the original repository was dead in 2010
[23:28] <superdump> and i'd forgotten about cog :)
[23:29] <kode54> then after pushing about 50 or more updates
[23:29] <kode54> I noticed that mamburu at bitbucket already forked and effectively took it over
[23:29] <kode54> the official update feeds redirect to his
[23:29] <kode54> one of the plugins is based on FFMPEG
[23:29] <kode54> I've done some silly things with that one
[23:30] <superdump> are you going to merge with that bitbucket one?
[23:30] <kode54> like modifying the libavformat MP3 parser to drop silly notions of seek tables
[23:30] <kode54> I am on bitbucket
[23:30] <kode54> but no idea if I can merge with either of the repositories in my current state
[23:31] <kode54> since I manually imported updates from the other fork, since a number of them would have conflicted with changes I already made
[23:31] <kode54> anyway, the FFMPEG thing
[23:31] <kode54> I rewrote the seek function in the MP3 parser so it walks the entire stream
[23:31] <kode54> and I added support for reading the delay/padding from iTunsMPB comments
[23:32] <kode54> and also the seeking operation will try to rollback by up to 8 frames and discard that many frames worth of samples in addition to part of the last frame for a sample exact offset
[23:32] <i336_> hi everyone. I have a rather basic graphics card in this PC atm, and while I can hear audio in the HD MP4 video I just downloaded off youtube, the a video window that opens is completely black. mplayer has options like '-vo x11' that cause it to render directly to X11 without optimization, and '-framedrop' to keep video playback 'fast', if choppy. What are ffmpeg's equivalents? I can't get my head around the plugin architecture :P
[23:32] <i336_> s/a video/video/ *
[23:33] <kode54> not sure I want to import the vorbis decoder and parser into my plugin though
[23:33] <kode54> since some people on the foobar2000 forum have encountered problems with it
[23:33] <i336_> (graphics optimization, that is - like opengl, which doesn't seem to want to work atm)
[23:33] <superdump> hmm
[23:33] <kode54> recent foobar adopted its own copy of ffmpeg with some codecs and parsers and demuxers enabled
[23:34] <kode54> with the binaries renamed because random idiot codec pack updaters will find the common libav*.dll and replace them with their own copy
[23:34] <superdump> orly? interesting
[23:34] <kode54> and foobar's is not binary compatible with the official
[23:34] <kode54> calling convention differences or something
[23:35] <kode54> instructions to build it are posted on the site, along with the package of source which was used to build the latest bundled
[23:35] <kode54> anyway
[23:35] <superdump> still windows only i see
[23:35] <kode54> the vorbis decoder fails on some really old vorbis files
[23:35] <kode54> yeah
[23:35] <kode54> portability is probably a 2.0 thing, if ever
[23:36] <kode54> and even then, people will have to either open source their components, or provide binaries for every goddamn supported platform
[23:36] <kode54> Peter already has a PFCv2 that works on Win/Mac/Linux
[23:36] <kode54> but I doubt that foobar will appear there unless he decides to make a generic GUI framework as well
[23:37] <kode54> then it will be total rewrites for all the components that have any Win32 code
[23:37] <superdump> PFC?
[23:37] Action: i336_ was going to say the same thing
[23:37] <kode54> his foundation classes which are included with the SDK
[23:38] <llogan> i336_: ffplay only supports sdl (if that is what you're asking).
[23:38] <i336_> llogan: oh :<
[23:38] <llogan> AFAIK
[23:38] <kode54> the PFC v1 included with fb2k is only compatible with Windows
[23:38] <i336_> and apparently doesn't provide any error feedback/detection if the video refuses to play
[23:39] <i336_> ffplay <video I just downloaded off youtube.mp4>
[23:39] <i336_> that's all
[23:39] <llogan> and there is no console output at all?
[23:39] <i336_> no, sorry, no video output - there is console output, but ffmpeg doesn't seem to realize the video isn't playing :P
[23:39] <i336_> or at least it isn't telling me, lol
[23:40] <llogan> i'm sorry, but i don't quite understand what the issue is
[23:40] Action: i336_ runs "ffplay video.mp4"
[23:40] Action: i336_ gets sound
[23:40] Action: i336_ gets a video window that is completely black
[23:40] Action: i336_ wonders what to do next
[23:40] <i336_> :P
[23:41] <llogan> you show the complete console output
[23:41] <superdump> kode54: sounds like probably not then
[23:41] <i336_> if you want...
[23:41] <superdump> anyway, i was just swinging through
[23:41] <superdump> have fun :)
[23:41] <superdump> o/
[23:41] <i336_> http://sprunge.us/UFiD
[23:42] <i336_> looks like normal output, but I can haz absolutely no video content :<
[23:43] Action: i336_ notes that the video is 1080p but that his display is 1024x768
[23:43] <llogan> do you see anything with: ffplay -f lavfi -i testsrc
[23:43] <i336_> oooooo, cute :> yes I do
[23:44] Action: i336_ points out that maintaining that causes X to use 17% CPU and ffplay ~30% in one thread, 13% in another, 9% in another and 5% in yet another
[23:45] <llogan> ffplay -f lavfi -i testsrc=s=hd1080
[23:45] <i336_> for a total of about 70% CPU (xmms chews cycles even when paused >.>)
[23:45] <i336_> black && 100% CPU usage
[23:46] <llogan> then i guess it's not the original video and I have no other ideas
[23:46] <i336_> mmm :/
[23:46] <i336_> I also fiddled with that command and 'hd720' doesn't work either, which is depressing :P
[23:47] <llogan> maybe someone on ffmpeg-user will have an idea.
[23:47] <i336_> oh ok.
[23:48] Action: i336_ discovers https://trac.ffmpeg.org/wiki/FancyFilteringExamples in the meantime
[23:48] <i336_> coooool :>
[23:48] Action: i336_ begins to understand why /usr/local/bin/ffplay is 11675564 bytes (ie 12MB)
