[01:18] <Mista_D> really?
[01:41] <TroubledTechnici> Morning gentlemen
[01:42] <TroubledTechnici> I was wondering whether somebody could give me a hand with an error I am receiving when trying to run ffserver after updating from source
[01:43] <TroubledTechnici> ffserver: relocation error: ffserver: symbol ffm_read_write_index, version LIBAVFORMAT_53 not defined in file libavformat.so.53 with link time reference
[01:44] <TroubledTechnici> any ideas?
[02:34] <TrixIsOwned> hey, I'm having a problem with files ending the stream before getting to the end of the file duration, http://pastebin.com/k4r9HTCn the log file doesnt seem to give any hints, this happens with avi's and mkv's as well
[04:54] <TroubledTechnici> hi guys. I am currently trying to get our tv stream setup to work in the browser by using ffmpeg. with ffserver running and using this command "ffmpeg -i rtp://238.255.1.5:5004 http://localhost:8090/feed1.ffm" but i keep receiving a http 403 forbidden message everytime. is there possibly a security settign I have missed somewhere alogn the way?
[04:56] <TroubledTechnici> http://pastebin.com/cR8Rc05B that is the message I receive
[05:06] <TroubledTechnici> anybody? your help would be appreciated
[05:26] <TroubledTechnici> so further testing by using a video file instead of the stream does the same thing. same message exactly. so it appears to be some sort of permissions/file issues
[05:26] <TroubledTechnici> I have chmod 777 the ffserver config and feed1.ffm file but that did not resolve the issue
[06:51] <TroubledTechnici> is there anybody here at all who can help me???
[06:53] <Sashmo> Sorry dude, everyone is sleeping
[06:53] <Sashmo> they are all inEurope, and sleeping now
[06:58] <TroubledTechnici> oh well :( I shall continue my google searching!
[06:59] <Sashmo> just try them in ab about 4 hours
[06:59] <TroubledTechnici> Shall do. thanks for that.
[09:05] <sine_> can someone suggest a really good codec pack that covers xvid nd x264 etc
[09:09] <ubitux> maybe ffmpeg?
[09:17] <sine_> for playback
[09:17] <sine_> say for instance mpc or vlc
[10:20] <nutron> So, I know this may be touchy.... but from my understanding... when I type ffmpeg -switches etc... am I actually running libav instead under debian?
[10:20] <nutron> If so... wtf.
[10:21] <ubitux> debian is packaging libav
[10:21] <ubitux> and the old version of libav has a old deprecated unmaintained version of ffmpeg
[10:21] <nutron> bah... why not call it that then..?
[10:21] <ubitux> propaganda i guess
[10:22] <nutron> oh eff.....  no point in reading the documentation then =/
[10:23] <nutron> question: on wikipedia, libav has a bunch more codecs listed than ffmpeg, but from my research it seems that ffmpeg is the winning (developed faster) project.  Is the wiki page correct or outdated?
[10:23] <ubitux> i don't know anyway "maintaining" the ffmpeg wikipedia page
[10:23] <nutron> I hate asking polarizing questions, so simply shoot  me if I piss anyone off.
[10:24] <ubitux> afaik libav duplicated the ffmpeg page and added its stuff
[10:24] <ubitux> but yeah, ffmpeg has more stuff
[10:24] <ubitux> no worry, you're not responsible for the confusion
[10:24] <ubitux> and that channel is appropriate for such talk :)
[10:25] <nutron> which channel?
[10:25] <ubitux> (s/anyway/anyone/)
[10:25] <ubitux> this one, #ffmpeg
[10:25] <nutron> this? or theirs?
[10:25] <nutron> ahh =)
[10:25] <ubitux> oh sure you can go talk to them as well :)
[10:26] <nutron> I'm confused about this whole thing... I think the deb maintainer needs to screw his head on straight and allow both projects to co-exist
[10:26] <ubitux> check http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html for a non-objective explanation
[10:26] <ubitux> the first part should be fairly objective though
[10:30] <nutron> I just came across this bs after starting some research on decoding bink video for a game.
[10:30] <nutron> Man the internet sucks the life outta ya sometimes.
[10:30] <nutron> ubitux: thanks for the link I started reading it.
[10:43] <nutron> bah .. what an ugly fuck-around....  g/l to ffmpeg, libav feels shitty and shady....
[10:44] <nutron> And now... I move on.
[10:44] <nutron> To understand bink!
[10:44] <nutron> Using ... ffmpeg =)
[10:46] <ubitux> have fun; but please don't bitch too much on libav, they are actually helping ffmpeg getting better sometimes (against their will though)
[10:48] <ubitux> IMO as a user all you can do to improve the situation is complain to your distribution for using ffmpeg name to package libav, and/or complain about making ffmpeg also available
[10:51] <nutron> Indeed.
[10:52] <nutron> is ffmpeg-mt ... multithreaded?
[10:54] <Mavrik> ffmpeg-mt was an old fork that implemented multithreaded decoding
[10:55] <Mavrik> it's merged in master for awhile now afaik
[10:55] <nutron> Sweet.
[12:10] <jmen> Hi! I'm try to configure ffmpeg, but it write error:
[12:10] <jmen> libfaac not found.
[12:10] <jmen> But ls /usr/lib/ | grep faac is:

[12:11] <jmen> Anybody here?
[12:11] <JEEB> see config.log :P

[13:09] <japjap> Hello
[13:10] <japjap> ffmpeg keeps saying:
[13:10] <japjap> non-existing PPS referenced
[13:10] <japjap> non-existing PPS 0 referenced
[13:10] <japjap> decode_slice_header error
[13:10] <japjap> no frame!
[13:10] <japjap> when running this:  ffmpeg -f h264 -i "rec.264" -vcodec libx264 "output.mp4"
[13:10] <japjap> any idea why ?
[13:52] <Andreas_> Hi! I have the following problem: i have two audio tracks in one MP4. One I like to disable because Quicktime plays them simultaniously with the other track. Is there any option?
[13:53] <Andreas_> the track should remain in the MP4 file. it should just set to be "deactivated" (like possible with MP4Box).
[13:53] <Andreas_> Any idea?
[13:55] <Andreas_> (ffmpeg v 0.11.1)
[14:07] <zap0> use a sensible player.
[14:07] <japjap> Is anyone familiar with RTPs ?
[14:10] <zap0> if you hum it...
[14:11] <Jax> hello, is it possible to merge two videos so they play next to each other?
[14:11] <Jax> or is there another tool for this
[14:11] <Jax> i just want to compare how two videos look
[14:15] <zap0> i would imagine there is.
[14:24] <japjap> zap0 ?
[14:25] <Jax> ffmpeg -i thresholded.mpg -s 400x200 -vf "movie=original.mpg, scale=200:200, setpts=PTS-STARTPTS, pad=400:200:200:0, [T1] overlay=0:0 [out]; [in] scale=200:200, setpts=PTS-STARTPTS [T1]" combined.mpg
[14:25] <Jax> seemed to do the trick.
[14:25] <zap0> nice!  thanks also for sharing it.
[14:27] <japjap> zap0 ?
[14:27] <japjap> u there ?
[14:40] <Jax> i noticed that when i extract images from an mpeg, that the first couple images are grey.. how do i get rid of those?
[14:40] <Jax> or how can i tell it to start extracting on a keyframe near my offset?
[14:41] <Jax> using -ss to offset
[14:43] <Andreas_> @zap0: "use a sensible player" is alas no option... i try to create a workflow and it has to run on Quicktime too
[14:46] <peili> I get an BadCursor Error when using x11grab as input: http://pastebin.com/kHPw1S7c
[14:46] <peili> Any idea?
[15:31] <Jax> hm
[15:32] <Jax> i'm using a -vf command and ffmpeg seems to hang after successfully creating the movie..
[15:32] <Jax> how can i prevent this?
[15:33] <ubitux> you need to give all the information necessary so we can reproduce first
[15:56] <Jax> ok
[15:57] <Jax> ffmpeg -i thresholded.mpg -s 2880x1080 -b 320000 -vf "movie=original.mpg, scale=1440:1080, setpts=PTS-STARTPTS, pad=2880:1080:1440:0, [T1] overlay=0:0 [out]; [in] scale=1440:1080, setpts=PTS-STARTPTS [T1]" combined.mpg
[15:57] <Jax> is the exact line i'm using
[16:00] <smj> how can I use ffplay in a terminal, without SDL or X or anything?
[16:02] <smj> -vn and -nodisp don't seem to help
[16:08] <smj> okay, 'ffmpeg -i <inputfile> -f alsa default' seems to do the trick
[17:57] <d4> hi
[17:59] <d4> If I call avcodec_find_decoder(enum CodecID id) it can never find a codec
[18:00] <d4> it always returns NULL
[18:00] <d4> How can this be?
[18:08] <d4> no one?
[18:09] <microchip_> d4: ask in #ffmpeg-devel
[18:11] <d4> microchip_: that channel is only for development on ffmpeg itself
[18:12] <microchip_> no
[18:12] <microchip_> if you want to ask about internals, you ask in #ffmpeg-devel
[18:12] <microchip_> this chan is only for USERS of ffmpeg, not internal API questions
[18:14] <d4> that was not an internal API question
[18:14] <d4> It was an API question ffmpeg is an API
[18:15] <d4> ffmpeg.c is an implementation of ffmpeg
[18:15] <microchip_> d4: dude, you asked about code. In here we don't ask such question but ones about how ffmpeg operates and its flags. Get it in your thick head
[18:17] <d4> Topic for #ffmpeg-devel: Welcome to the FFmpeg development channel. | Discussions about the development of FFmpeg itself are ontopic here. | Questions about using FFmpeg or developing with the libav* libraries should be asked in #ffmpeg | Prores lives ! | This channel is publically logged | FFmpeg 0.11.1 has been released
[18:17] <d4> dude...
[18:19] <microchip_> d4: no one will answer your question here, except ubitux maybe
[18:20] <d4> So you are saying that they should change the subject of the channels and their rules are wrong
[18:21] <microchip_> no, i'm saying that you have better chance of an answer in #ffmpeg-devel
[18:21] <microchip_> d4: in here, people come and ask but no one answers, that's why i redirected you to -devel
[18:22] <microchip_> (trust me, i've seen many asking, and no one answering :D)
[18:22] <d4> thats not what you said
[18:23] <microchip_> d4: fine, stay here and wait for an answer :)
[18:23] <d4> No I already asked in devel
[18:23] <d4> lol
[18:23] <microchip_> good!
[18:23] <microchip_> did anyone help?
[18:23] <d4> yeah :p
[18:23] <microchip_> cool
[18:23] <microchip_> :D
[18:23] <d4> thanks :P
[18:24] <microchip_> no problem :)
[18:31] <microchip_> d4: did you solve your problem? if not, try pinging michaelni (main dev of ffmpeg). Maybe he knows the answer
[18:57] <ubitux> d4: did you get your answer?
[19:08] <user_> hi, is ac3 better than mp3 in high bitrates ?
[19:08] <user_> and mp3 is better than ac3 on less bitrate ?
[19:31] <Olson> im getting really poor performance from ffmpeg + X11grab for recording screen.. it seems what ever I do nowadays the recording FPS can't keep up with what I set it to, and the audio is going out of sync over time. In the past i've recorded at 30fps, nowadays it can't even do 20, it'll drop to 19 or so and gradually the audio desyncs
[19:32] <ubitux> you should try to do a fast lostless capture at first
[19:32] <ubitux> and then do a proper re-encoder
[19:32] <ubitux> -r
[19:32] <Olson> indeed, that is what I am trying sir
[19:32] <Olson> ffmpeg -f alsa -ac 2 -i hw:1,0 -f x11grab -r 60 -s 1920x1080 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -threads 2 output.avi
[19:33] <Olson> except that -r 60 is supposed to be 20
[19:33] <Olson> i just testing some things
[19:33] <ubitux> not better with x264opts qp=0 ?
[19:34] <Olson> I've not head of this option before
[19:34] <Olson> I recall that before when using -vpre there was option lossless_ultrafast though that seems to be changed now
[19:34] <ubitux> about syncing audio i'd be curious to know how to solve that; maybe -async 1 or something; also, i hope you try a recent enough ffmpeg
[19:35] <Olson> i built ffmpeg from source just the other day
[19:36] <Olson> it's not a one off audio dysync, it gets worse over time.. at the beginning of video it would be fine, then depending how long the recording FPS has been below the desired one audio desyncs as time goes on
[19:36] <Olson> could you tell me how to use h x264opts qp=0 within the space of my commandline?
[19:37] <ubitux> -x264opts qp=0 ?
[19:37] <Olson> around where -preset is
[19:37] <ubitux> yes, as output option
[19:37] <Olson> thank you
[19:38] <ubitux> (not sure it will help)
[19:38] <ubitux> (but you'll get lossless stuff at least)
[19:38] <Olson> it used to be fine, this recording and I dont know what happened since, it's kinda put my work on hold and stuff
[19:42] <ubitux> i get around 30 fps here
[19:42] <Olson> indeed
[19:43] <Olson> now it's recording at onlly 7fps and lagging my system...
[19:43] <ubitux> :p
[19:44] <Olson> :*(
[19:45] <Olson> http://pastebin.com/yukk9YJp
[19:46] <Olson> something is terribly wrong
[19:47] <ubitux> no idea, and i have to go :(
[19:47] <ubitux> i'm curious if you find the answer
[20:36] <^prelude^ZZz> hello everyone
[20:36] <^prelude^ZZz> can i ask a few technical question
[20:37] <^prelude^ZZz> im capturing some data with ffmpeg.. and it is just acopy and vcopy and after some time it exists with No more inputs to read from,.
[20:37] <^prelude^ZZz> but its a live stream, it should never end
[20:37] <^prelude^ZZz> is there a flag to say ignore time or whatever so it keeps streaming
[20:50] <lemonjelly> hello, is there a command line option to the "ffmpeg" binary to make it behave like "ffprobe"?
[22:55] <TrixIsOwned> hey, I'm having a problem with files ending the stream before getting to the end of the file duration, http://pastebin.com/k4r9HTCn the log file doesnt seem to give any hints, this happens with avi's and mkv's as well
[23:56] <boudiccas> when using winff to convert a mp4 file to avi on squeeze, it fails everytime with ... /usr/bin/ffmpeg: unrecognized option '-vf' .... does anyone have any idea how i can get round this please?
