[04:26] <whiplash> hey guys
[04:27] <whiplash> got a question here, not exactly related to ffmpeg but i thought you guys might be able to help
[04:27] <whiplash> i'm trying to write a vfw codec that utilizes intel's quick sync feature
[04:27] <whiplash> and i'm having trouble building the encoder example
[04:28] <whiplash> this is the sdk: http://software.intel.com/en-us/vcsource/tools/media-sdk
[04:28] <whiplash> according to the documentation, it should be built using vs2012 on windows 8
[04:54] <thevdude> :/ I've got an mp4 video and I'm trying to cut a short section out. The video has aac audio and h264 video, and apparently I want to split it off of an I frame (whatever that is), so setting -vcodec h264 works fine for that (and the video starts where I want it to), but the audio seems to be playing from that I Frame instead.
[04:55] <thevdude> I'm doing -acodec aac and setting the other settings to match the old one
[04:55] <thevdude> trying -async 1 now
[04:56] <thevdude> audio matches up at about 4seconds in, but is missing before that :/
[05:28] <qeed> hi, im using ffmpeg to encode some image files into a video, ffmpeg -f image2 -r 1 -i pix/%03d.png -target ntsc-dvd -aspect 4:3 out.mpg the command im using
[05:28] <qeed> for some reason some of the png files is opened but skipped and not encoded
[05:28] <qeed> (from what i see from strace) is there a reason how that can be?
[05:29] <qeed> i looked at the images being skipped, the dimensions to them are bigger than the ones that are encoded 3264 x 2448
[05:29] <qeed> other than the dimension it the png encoding is the same
[05:46] <nachii> hello
[05:46] <nachii> i have a problem with a video h264
[05:46] <nachii> can somebody help me?
[05:48] <nachii> can anybody help me?
[05:48] <nachii> http://pastebin.com/HtWy1CSi
[05:48] <nachii> there it is the line i use and the reslt
[05:48] <nachii> result
[05:58] <nachii> please anyone?
[06:03] <nachii> can anybody help me?
[06:03] <nachii> i have a problem with a video h264
[06:03] <nachii> http://pastebin.com/HtWy1CSi
[06:03] <nachii> there it is the line i use and the result
[06:05] <qeed> i found some online answers saying it has to be the same size, so i guess i need to resize them
[06:33] <brimestone> Im getting a weird result when i add -timecode my footage end  up 5 times longer than it should..
[11:11] <Marlinc> Is it possible to get
[11:11] <Marlinc> frame=   23 fps=  5 q=23.9 Lsize=     813kB time=6.60 bitrate=1008.9kbits/s
[11:11] <Marlinc> Is it possible to get
[11:11] <Marlinc> More frequent?*
[13:43] <burek> Marlinc, what exactly are you trying to accomplish?
[13:44] <burek> can you provide a pastebin of your command line + output?
[13:45] <burek> thevdude can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[13:52] <Marlinc> ffmpeg -y -f x11grab -i 1300x744|:0.0+65,24 -r 60 -s 2806x900 -b 50k -minrate 50k -maxrate 50k -bufsize 1835k -vcodec libx264 -f flv hoi.flv
[13:52] <Marlinc> brb
[13:53] <Marlinc> Back
[13:53] <Marlinc> burek, ^
[13:54] <burek> are you sure this is valid "-f x11grab -i 1300x744|:0.0+65,24"
[13:54] <burek> http://ffmpeg.org/ffmpeg.html#x11grab
[13:55] <burek> maybe you wanted to say something like this: -f x11grab -s 1300x744 -i :0.0+65,24
[13:56] <Marlinc> I thought the same
[13:56] <burek> unless your 'hostname' is actually named '1300x744|'
[13:56] <burek> which is not likely
[13:56] <Marlinc> But okay
[13:57] <Marlinc> My question was about the " frame=   23 fps=  5 q=23.9 Lsize=     813kB time=6.60 bitrate=1008.9kbits/s" messages
[13:57] <burek> Marlinc can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[13:58] <Marlinc> https://gist.github.com/08b41b27125186e90d05
[13:59] <burek> you are not using ffmpeg
[13:59] <Marlinc> apparently avconv is the same as ffmpeg
[13:59] <Marlinc> According to the ffmpeg command
[14:00] <burek> if it was, you would be using ffmpeg
[14:00] <burek> go to libav support channels and ask there for the support
[14:00] <burek> it's just a fork project of ffmpeg
[14:00] <Marlinc> The ffmpeg command saids that ffmpeg is deprecated
[14:00] <burek> ubitux :)
[14:00] <Marlinc> And that I should use avconv
[14:00] <burek> we should really create that wiki page
[14:00] <Marlinc> *** THIS PROGRAM IS DEPRECATED ***
[14:00] <Marlinc> This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
[14:00] <burek> that explains all the mess that debian/ubuntu maintainers have created..
[14:01] <burek> Marlinc, long story short
[14:01] <Marlinc> I see...
[14:01] <burek> that's a lie..
[14:01] <burek> sadly..
[14:01] <Marlinc> Okay..
[14:01] <burek> they forked ffmpeg project and wanted all people to just forget about ffmpeg
[14:01] <burek> just like it never existed
[14:01] <burek> can't help much about that
[14:01] <burek> but if you install ffmpeg I might help
[14:01] <Marlinc> Okay that's pretty sad
[14:01] <burek> until then, you'll have to ask there
[14:02] <burek> i know..
[14:02] <Marlinc> As far as I know I have ffmpeg installed
[14:02] <burek> we will soon create a page where people will be able to get ffmpeg deb package from
[14:02] <Marlinc> Okay
[14:02] <burek> but until then, you'll just have to compile it from source..
[14:02] <Marlinc> So
[14:02] <Marlinc> I'm creating a software package
[14:02] <Marlinc> That uses ffmpeg (or avconv)
[14:03] <Marlinc> And I would like to use the apt software manager for Ubuntu
[14:03] <Marlinc> So using debs
[14:03] <Marlinc> As a way to distribute the software
[14:04] <Marlinc> Does the matter if I specify ffmpeg as dependency?
[14:04] <Marlinc> Because it looks like it installs avconv if that's what you're saying
[14:05] <burek> you might join #ffmpeg-devel and ask there, because it's kinda mess right now with debian/ubuntu
[14:05] <burek> so to get the precise answer
[14:05] <burek> you would need to ask developers for advice
[14:06] <Marlinc> Damn
[14:06] <Marlinc> Are there bug differences?
[14:06] <Marlinc> Big*
[14:06] <burek> obviously :)
[14:06] <Marlinc> Can I use ffmpeg and avconv with the same arguments?
[14:06] <burek> I wouldn't know, since I don't use avconv, so, I dunno really..
[14:07] <Marlinc> Okay
[14:07] <Marlinc> But okay is it possible in ffmpeg
[14:07] <Marlinc> To get the " frame=   23 fps=  5 q=23.9 Lsize=     813kB time=6.60 bitrate=1008.9kbits/s" messages more frequently
[14:07] <Marlinc> I'm assuming ffmpeg has it too?
[14:08] <burek> why do you need those log messages more frequent?
[14:08] <Marlinc> Because I'm using the fps and frame parts in my application
[14:09] <Marlinc> I'm trying to make a indicator that activates if the fps drops or the amount of frames get slowed down
[14:09] <burek> maybe -log_level 99 ?
[14:09] <Marlinc> And I can't really create a accurate indicator if I don't get the frame amount that often
[14:09] <burek> did you check the docs?
[14:09] <Marlinc> Yes but I didn't know that to look for
[14:10] <Marlinc> I did use the man page
[14:10] <Marlinc> brb
[14:12] <King_Rat> could anyone give me some help with using x11grab for fullscreen wine windows?
[14:12] <Marlinc> back
[14:12] <King_Rat> i dont really have a clue how fullscreen programs like that work
[14:13] <Marlinc> Unrecognized option 'log_level'
[14:13] <Marlinc> Failed to set value '99' for option 'log_level'
[14:13] <Marlinc> :p
[14:13] <Marlinc> burek, ^
[14:13] <burek> it's not ffmpeg..
[14:14] <King_Rat> do any of x's numerous little tools allow you to list all displays?
[14:14] <burek> maybe -loglevel
[14:14] <burek> instead of log_level
[14:14] <burek> or something
[14:14] <Marlinc> O yes..
[14:14] <burek> Marlinc: http://ffmpeg.org/ffmpeg.html
[14:14] <burek> ctrl+f loglevel
[14:14] <Marlinc> I thought I changed the command but yes.. Ubuntu uses avconv
[14:15] <Marlinc> What mess
[14:15] <burek> King_Rat: https://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20grab%20the%20desktop%20(screen)%20with%20FFmpeg
[14:15] <Marlinc> Is it possible to provide a binary with my software?
[14:15] <Marlinc> Or would it cause library problems
[14:16] <burek> Marlinc, if you're asking for licensing stuff or so, read here: http://ffmpeg.org/legal.html
[14:16] <burek> for libs dependencies and stuff, please ask in #ffmpeg-devel, since I can't help a lot with it
[14:16] <Marlinc> Okay
[14:16] <King_Rat> when I try and capture in fullscreen everything goes black
[14:17] <Marlinc> Really realizing this software is getting harder and harder
[14:17] <m3thyl> when creating a video from from images, with an explicit video size (i.e "-s WxH"), is there a way to have the image preserve its aspect while fitting within the boundaries of the video (the images are resizing to WxH, but don't necessarily have a W:H aspect ratio)
[14:18] <burek> m3thyl you might use pad filter
[14:18] <burek> http://ffmpeg.org/ffmpeg.html#pad
[14:18] <burek> King_Rat can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[14:19] <m3thyl> ok; i was looking at that but was wondering if ffmpeg could do the calculations for me; thanks
[14:19] <burek> Marlinc, at least it's never boring :)
[14:19] <King_Rat> wait, i'll brb in 10 minutes or so
[14:19] <burek> m3thyl, it can, just take a look at examples
[14:19] <m3thyl> alright
[14:36] <Marlinc> burek, https://gist.github.com/a830ddb9d1038367bacb
[14:36] <Marlinc> Whats the difference between the two frame amounts
[14:37] <Marlinc> One says 281 and the other says 323
[14:38] <burek> shevy, did you try: ffmpeg -i input.mpg -map 0 -c copy -c:v libx264 -crf 25 -preset slow output.mp4
[14:39] <burek> Marlinc one is reported by ffmpeg (that is calling the libx264 lib) and another is the output of the libx264 lib itself
[14:39] <burek> the timing of those 2 is what makes it different
[14:39] <Marlinc> Okay..
[14:40] <burek> (I guess)
[14:40] <burek> btw, if you need that accuracy, why don't you code your own libav* wrapper
[14:40] <burek> instead of using cmd line
[14:41] <burek> or modify ffmpeg to display that log line more frequently and recompile it again
[14:41] <Marlinc> I'm using Java because it makes it easier to make it cross-platform
[14:41] <shevy> burek not yet, will try, thanks
[14:41] <burek> and java is calling ffmpeg?
[14:41] <burek> shevy :beer: :)
[14:41] <shevy> hehe
[14:41] <Marlinc> Yes at the moment I'm using the ProcessBuilder class from Java
[14:42] <burek> that means you'll expect from the end-users to have to install ffmpeg on their computer prior to using your app?
[14:43] <Marlinc> I'll let the application download it I think
[14:43] <Marlinc> Or provide it in the package
[14:43] <Marlinc> For Ubuntu I can simply add a dependency to the deb file
[14:43] <burek> if you provide it in the package, you'll have to know the target platform before you pack it
[14:43] <Marlinc> I know
[14:43] <burek> to know which ffmpeg binary to pack (exe, elf, etc)
[14:44] <Marlinc> But I already need to that because of SWT (the window library I'm using)
[14:44] <burek> also, I think, legally, you'll have some issues if you "just pack ffmpeg binary" into your app package
[14:45] <Marlinc> Then I think I should do the same as ffsplit
[14:45] <burek> did you read this already: http://ffmpeg.org/legal.html
[14:45] <burek> it might help
[14:45] <Marlinc> Okay
[14:45] <burek> just so you don't waste time on something that will end up like not recommended approach anyway
[14:46] <Marlinc> Yes I would need some help with that
[14:48] <Marlinc> But okay
[14:49] <Marlinc> I'm running the ffmpeg library quite literally
[14:49] <Marlinc> The application just provides the right arguments
[14:50] <burek> you mean binary?
[14:51] <ubitux> burek: still need help?
[14:51] <burek> always :)
[14:51] <Marlinc> binary yes
[14:51] <Marlinc> Sorry
[14:52] <ubitux> i guess i'll have to backlog?
[14:52] <burek> Marlinc is one of those debian/ubuntu users
[14:52] <burek> who were affected by avconv and stuff
[14:52] <burek> so, in order not to advise him badly, I've asked you (and others) to suggest Marlinc what should he do
[14:52] <Marlinc> Jup..
[14:53] <ubitux> does the static build solve his problem?
[14:53] <Marlinc> You're asking burek right?
[14:54] <ubitux> yeah but talking about you :p
[14:54] <Marlinc> :p
[14:54] <burek> I didn't advise him to use static build, as I didn't know what exactly is his use case
[14:54] <ubitux> Marlinc: did you try the static build? :)
[14:54] <Marlinc> Nope
[14:54] <ubitux> ok ok well, i just woke up, give me a few minutes i'll backlog
[14:54] <burek> ok :)
[14:54] <Marlinc> I just heard about the difference between avconv and ffmpeg
[14:55] <Marlinc> I though it was the same so I could just use the Ubuntu package and have the same results on other platforms using ffmpeg itself
[14:58] <ubitux> ok well, first i don't even understand what the problem is
[14:58] <ubitux> Marlinc: do you mind explaining again what's not working?
[14:59] <Marlinc> There wasn't really a problem
[14:59] <Marlinc> More of a question
[14:59] <Marlinc> I'm using the "frame=  323 fps= 10 q=69.0 size=     192kB time=27.65 bitrate=  56.8kbits/s" messages to provide some useful information in my application
[14:59] <Marlinc> But because it only shows op like one's a second?
[15:00] <Marlinc> I can't really provider accurate data
[15:00] <Marlinc> Provide*
[15:00] <Marlinc> So my original question if it is possible to get those status messages more often
[15:01] <Marlinc> So my original question was if it is possible to get those status messages more often
[15:01] <ubitux> check if the -progress option has a higer rate
[15:01] <ubitux> higher*
[15:02] <Marlinc> Okay thanks
[15:02] <Marlinc> I didn't know what to look for
[15:02] <Marlinc> So thats why I came here
[15:02] <ubitux> it might be the same, but it looks easier to exploit for apps than the cmd output you're pasting
[15:03] <ubitux> i never used it so well..
[15:03] <ubitux> anyway, i'm not sure it's available in the fork
[15:03] <ubitux> so if not
[15:03] <Marlinc> Okay thanks
[15:03] <ubitux> you can try this ^
[15:03] <Marlinc> Is it allowed to provide the binary package with my application?
[15:03] <ubitux> and check if it helps with your problem
[15:03] <ubitux> it depends
[15:04] <Marlinc> It isn't commercial
[15:04] <ubitux> is the source code available?
[15:04] <Marlinc> Fully open-source
[15:04] <ubitux> it also depends if you build ffmpeg with --enable-gpl or no
[15:05] <Marlinc> I read about some license problems with libx264?
[15:05] <Marlinc> On the legal page
[15:05] <ubitux> as well as if you build it with --enable-nonfree and stuff like that
[15:05] <Marlinc> Because I do need libx264
[15:05] <ubitux> i'm not sure, but afaict, the safe choice is to have your app under GPL
[15:06] <ubitux> but i'm not a lawyer so..
[15:06] <Marlinc> But one moment going to take a look at the progress option
[15:07] <ubitux> mmh afaict it seems the progress rate is also 1 second
[15:09] <ubitux> do you really need a higher rate?
[15:09] <Marlinc> I'm trying to make a indicator so the user of the application can listen to the amount of FPS he has
[15:09] <Marlinc> While in game
[15:10] <Marlinc> So he can hear what happens to the FPS when he is in game
[15:10] <Marlinc> Without looking at the application
[15:10] <ubitux> huh?
[15:11] <Marlinc> How do I explain it
[15:11] <Marlinc> When in game you can't see the FPS of ffmpeg right?
[15:11] <Marlinc> Because your games window is in front of it
[15:12] <Marlinc> You can't see ffmpeg and you can't see my application that runs ffmpeg
[15:12] <Marlinc> Okay?
[15:12] <ubitux> yeah right ok
[15:12] <ubitux> and then why ~1 second is not fast enough?
[15:12] <Marlinc> My application makes a sound every 50 frames or so
[15:13] <Marlinc> So the use can sort of listen to the speed of the frames
[15:13] <Marlinc> So the user can sort of listen to the speed of the frames
[15:13] <Marlinc> Sometimes it doesn't work correctly because there is to much time between progress update
[15:14] <ubitux> well, increasing the rate will likely slowdown the processssssssss
[15:14] <ubitux> oups
[15:14] <Marlinc> Could have various reasons one being the FPS goes very high. Higher then 50 fps and thus missing a beep
[15:14] <ubitux> progress*
[15:14] <Marlinc> Really that much?
[15:15] <ubitux> i'm not sure how much but well...
[15:16] <ubitux> anyway, your approach looks weird
[15:16] <Marlinc> I don't know what is does on the ffmpeg backend but isn't it just a message?
[15:16] <ubitux> what would happen if you have a sound each 50 frames and ffmpeg was producing 50 frames each 0.0001 sec?
[15:17] <Marlinc> That's not likely
[15:17] <ubitux> why?
[15:17] <Marlinc> It is for live streaming
[15:17] <ubitux> ok
[15:17] <ubitux> anyway, the fps is printed every second for obvious reason
[15:18] <Marlinc> Pretty obvious indeed
[15:18] <ubitux> since it counts the number of frame per second :p
[15:18] <ubitux> another solution would be to use the api
[15:18] <ubitux> and do something every 50 frames
[15:18] <Marlinc> Okay
[15:19] <Marlinc> Are there Java bindings for the API?
[15:19] <ubitux> no
[15:19] <ubitux> ah maybe you could trick with -vf showinfo
[15:20] <Marlinc> What would that do?
[15:20] <ubitux> and parse the n value
[15:20] <Marlinc> Moment I'll try it
[15:20] <Marlinc> See what it does
[15:23] <Marlinc> How does it work ubitux ?
[15:23] <burek> try ffmpeg -f lavfi -i testsrc -t 10 -vf showinfo -f null /dev/null
[15:24] <burek> ffmpeg -f x11grab -i ... -vf showinfo -f null /dev/null
[15:24] <ubitux> *"-f null -" is even simpler!)
[15:24] <ubitux> ("-f null -" is even simpler!)
[15:24] <burek> oh right
[15:24] <Marlinc> Ah I see
[15:25] <Marlinc> And n provides the frame?
[15:25] <ubitux> it's the frame count
[15:25] <Marlinc> Ah nice
[15:25] <Marlinc> So I get info about every frame
[15:26] <burek> http://ffmpeg.org/ffmpeg.html#showinfo
[15:26] <ubitux> yes
[15:26] <Marlinc> Thats I'll take a look
[15:26] <Marlinc> Thanks*
[15:28] <Marlinc> What did the -t option do?
[15:28] <Marlinc> Time in seconds?
[15:28] <burek> http://ffmpeg.org/ffmpeg.html#Main-options
[15:28] <Marlinc> Ah
[15:28] <Marlinc> Okay
[15:29] <Marlinc> Thanks I'll see that I can do with this
[17:12] <thevdude> It's been a while. My issue is that audio isn't starting from where I'm telling the video to start from when cutting a clip out, it's starting from the I frame before the cut.
[17:14] <thevdude> command is ffmpeg -ss 00:05:13.0 -i ~/videos/to_trim.mp4 -vcodec h264 -acodec aac -ac 2 -ar 48000 -ab 225k -t 00:00:14.0 -strict -2 -y ~/videos/trimmed.mp4 and output is http://sprunge.us/ZjcS
[17:18] <relaxed> thevdude: move the seek after the input, and -vcodec libx264
[17:18] <thevdude> :/ my video is fine, but I'll try it
[17:18] <thevdude> the video is starting in the right place, the audio isn't.
[17:18] <relaxed> add -async 1
[17:19] <thevdude> that makes the audio sync up after about 4 seconds
[17:19] <thevdude> and makes grey frames show up at the start, let me try it with all the changes
[17:19] <spaam> :D
[17:22] <thevdude> holy poop it works
[18:29] <Marlinc> So I just noticed that ffmpeg can run using pipes
[18:29] <Marlinc> Is possible to have one output
[18:29] <Marlinc> And multiple input processes
[18:30] <Marlinc> And switch between multiple inputs so that something else appears on the output stream?
[18:30] <Marlinc> If so can somebody push me in the right direction?
[18:31] <Marlinc> burek, ubitux ?
[18:33] <ubitux> i don't understand
[18:34] <Marlinc> You can pipe video output from one process to the other right?
[18:36] <ubitux> yes?
[18:36] <ubitux> -f rawvideo -pix_fmt ...
[18:37] <Marlinc> Okay
[18:37] <Marlinc> So is it possible to switch between inputs?
[18:39] <ubitux> i don't know what that means :p
[18:40] <Marlinc> So I would have multiple ffmpeg
[18:40] <ubitux> ffmpeg -i ... -i ... -i ... ?
[18:40] <Marlinc> So I would have multiple ffmpeg's that read a file and put the output to stdout
[18:40] <Marlinc> Okay?
[18:40] <Marlinc> And one ffmpeg that reads the video from stdin
[18:41] <ubitux> really i have a hard time figuring out what you want to achieve.
[18:41] <Marlinc> I don't know how to explain it..
[18:42] <ubitux> describe what are your different inputs, and what's your output
[18:42] <Marlinc> For example
[18:42] <Marlinc> One ffmpeg captures my screen
[18:42] <Marlinc> One captures a file
[18:42] <Marlinc> And then I have a ffmpeg that reads from stdin and puts it on a livestream
[18:42] <Marlinc> See where I'm going?
[18:43] <ubitux> how do you want to merge those 3 inputs?
[18:43] <ubitux> you want one livestream out of these 3?
[18:43] <Marlinc> Yes but I don't want to merge
[18:43] <Marlinc> I want to be able to select which one gets send to the livestream
[18:43] <Marlinc> And switch between them without stopping the streaming
[18:44] <ubitux> i'd say you would push to 3 ffm streams on a ffserver and let the user decide which one to lurk
[18:44] <ubitux> otherwise i dunno
[18:45] <ubitux> with the api most likely
[18:45] <ubitux> with the tool dunno
[18:45] <Marlinc> Okay okay..
[18:45] <Marlinc> I think I'm just going try some things and see what it does
[18:47] <klaxa> quick question, how do i apply the fade video filter correctly? as of now it isn't giving me any results here's the ffmpeg output and input: http://pastebin.com/9cG4txEH
[18:49] <ubitux> works for me, and it should start fading around frame 960
[18:49] <ubitux> with your cmd line
[18:50] <klaxa> ah fuck... that was my bad the video has 900 frames :P
[18:51] <ubitux> it should do something like what you get with ./ffplay -f lavfi -i testsrc -vf fade=out:50:40
[18:51] <ubitux> (at 2 seconds)
[18:51] <ubitux> (25 fps)
[18:54] <klaxa> yes works perfectly, was totally me being stupid
[18:54] <ubitux> klaxa: btw, sameq doesn't mean sameq
[18:55] <ubitux> same quality*
[18:55] <ubitux> :)
[18:55] <ubitux> also, why do you select mpeg4 codec?
[18:58] <burek> ubitux, could 'select' video filter maybe be upgraded so that it supports selecting an input stream (just like -map does) based on some criteria
[18:58] <burek> that could solve the switching input's problem :)
[19:01] <ubitux> someone could write a streamselect right :)
[19:01] <ubitux> could be fun
[19:01] <ubitux> shouldn't be that hard
[19:01] <ubitux> maybe there are some problem between framerate or resolution mismatch
[19:02] <burek> yes but it can always spit out an error and refuse to play along if prerequisites are not met :)
[19:03] <burek> it would be like watching the tv :)
[19:03] <ubitux> you tv spit out errors?
[19:03] <ubitux> your*
[19:03] <ubitux> i'm not willing to write such filter anyway
[19:03] <ubitux> but yeah, that could be done
[19:04] <burek> I was just asking if it would be too much of work, so that I know if it makes sense to write a feature request :)
[19:05] <ubitux> could make sense yes
[19:07] <klaxa> <@ubitux> also, why do you select mpeg4 codec? <-- because the video will be played on a machine i don't know, i don't want it to lag, quality is good enough, i didn't notice any artifacts
[19:09] <ubitux> ok
[19:42] <thevdude> http://www.youtube.com/watch?v=9JsDU3CuWNs this is what you guys helped me do. <3 thanks.
[19:44] <ubitux> is it me or most of the sound is on the left channeL?
[20:50] <shevy> Codec is experimental but experimental codecs are not enabled, try -strict -2
[20:50] <shevy> ^^^ Anyone knows how to enable experimental codecs? so I can omit typing -strict -2
[20:50] <shevy> is from converting a .flv to .mp4
[21:15] <burek> shevy, why do you need to omit -strict -2
[21:15] <burek> or -strict experimental (same thing)
[21:24] <shevy> burek I dunno, it seems to be not useful for me to type it
[21:26] <shevy> I suppose there is no configure option to allow this
[21:26] <shevy> (I compile ffmpeg from source usually)
[21:35] <burek> it's not a configure option
[21:35] <burek> but cmd line option
[21:37] <klaxa> why not just alias ffmpeg in your .bashrc (or whatever shell you are using)
[21:58] <nachii> hello, can anybody help encoding mp4 to flv? i am getting an error
[21:58] <nachii> i can past it in paste bin
