[00:00] <llogan> i guess. i've never used it.
[00:00] <llogan> probesize default is sudo checkinstall --pkgname=libvpx --pkgversion="1:$(date +%Y%m%d%H%M)-git" --backup=no \
[00:00] <llogan> wrong paste obviously
[00:00] <llogan> probeseize default ~5 Mo
[00:01] <dmitrykharlamov> thanks for helping me again llogan!
[00:01] <dmitrykharlamov> I'm trying to increase the probesize during probing, just a min
[00:01] <llogan> i'm not very familiar with those options but maybe they'll work for you
[00:03] <dmitrykharlamov> analyzeduration did not yield any results
[00:03] <dmitrykharlamov> still the same error
[00:04] <llogan> maybe your probe needs to be bigger (sounds painful).
[00:05] <dmitrykharlamov> lol
[00:05] <dmitrykharlamov> what do you mean?
[00:06] <llogan> -probesize <integer>
[00:06] <llogan> where did your input files come from?
[00:08] <dmitrykharlamov> ah-ha. It actually just worked. And the files I've been trying to test it on do seem damaged. Which is good and bad news at the same time
[00:08] <llogan> what probesize did you use?
[00:08] <dmitrykharlamov> when I set the -probesize to say 100, it then says that /path/video.mp4 is an invalid argument
[00:09] <dmitrykharlamov> without probesize it worked
[00:09] <dmitrykharlamov> when I enter 'ffmpeg -probesize 100 -i /video.mp4' it says that /video.mp4 is an invalid argument
[00:12] <dmitrykharlamov> k, thanks very much for your help! I have found a problem on my end now!
[00:12] <llogan> dmitrykharlamov: glad you figured it out
[00:50] <Freakshow> I'm trying to capture the total number of bytes going out on a per stream basis, currently we've figured out the raw video, audio and sub-title data... but the decoded bitrate on the consumer side appears to vary a little more than expected. Is there a way to capture the true output data packet size taking into consideration network packaging overhead?
[00:50] <Mista_D> Any explanation on why MP4 atom moov/trak(X)/tkhd/flag = 15? Should be 1 or 7 (ISO/IEC 14496-12:2004).
[01:19] <DelphiWorld> burek :-P
[01:54] <burek> johnbender, did you try reading the docs? :))
[01:54] <burek> DelphiWorld hi :)
[01:54] <DelphiWorld> burek: ;
[01:56] <burek> Freakshow, install tcpdump or pktstat
[01:56] <burek> Mista_D, ask in #ffmpeg-devel
[01:56] <burek> oh you already did ^^
[01:59] <Freakshow> burek: doing this in ffmpeg.c
[02:00] <Freakshow> since the output logging is basically broken on a non-seekable output
[02:02] <burek> why would you measure the bit rate in the code?
[02:02] <burek> on the consumer side you could use vlc
[02:02] <burek> and go to tools - codec information
[02:02] <burek> tab statistics
[02:03] <Freakshow> right, need this to scrap locally as we're using ffmpeg in an encoder on the client side
[02:03] <Freakshow> scrap+e
[02:03] <Freakshow> for output statistics
[02:05] <Freakshow> it looks like in ffmpeg.c there was a comment to fix seeking in live streams
[02:05] <Freakshow> this is kind of in reference to my ticket against output logging with rtsp
[02:05] <Freakshow> https://ffmpeg.org/trac/ffmpeg/ticket/1446
[02:06] <Freakshow> I haven't seen any movement on the ticket, so we're fixing it ourselves and if it's worthwhile, we'll submit it for review as the resultant output data is much more accurate
[02:07] <Freakshow> isn't it really late (or early) for you burek ?
[02:46] <DelphiWorld> how to bind mysql to a specific ip?
[02:47] <DelphiWorld> oh
[02:47] <DelphiWorld> sory
[02:47] <DelphiWorld> not here;(
[07:13] <bwalker8981> Hi I'm trying to install the xuggler extension to ffmpeg, but when I run ant, I get build failed and it reports "/buildhelper.xml:1127: exec returned: 1". Any suggestions?
[07:13] <bwalker8981> Or does anyone know what that means?
[07:23] <bwalker8981> Does anyone know how to install xuggle for ffmpeg?
[08:19] <rohankasat> hi , can anybody tell me . how ffmpeg calls a decoder ( from the different registered decoders) , so that it can process further ? any particular function call or wat ?
[08:21] <t4nk823> hi , can anybody tell me . how ffmpeg calls a decoder ( from the different registered decoders) , so that it can process further ? any particular function call or wat ?
[09:22] <johnbender> burek: I did, I've been going over them for a few hours
[09:22] <johnbender> I think I need more background on basic video configuration :(
[09:33] <johnbender> burek: I should say, I _was_ going over them for a few hours before I posted my question
[09:33] <johnbender> I also tried building ffmpeg from git
[09:34] <johnbender> unfortunately I was getting "invalid dropping"
[09:43] <johnbender> in the meantime
[09:43] <johnbender> I'm back :(, still experiencing a 4 to 5 second lag (seems consistent) in my webcam overlay. Still not sure how to correct it https://gist.github.com/84f47d78cccbf0c632e0
[09:43] <johnbender> as mentioned I've spent a long time on this without getting anywhere
[09:44] <johnbender> I have little knowledge of how video manipulation works
[09:44] <johnbender> so that makes it harder to figure out
[10:56] <astropirate> is it possible to pipe audio from gst-launch into ffmpeg capture?
[11:03] <saste> astropirate: ffmpeg -i -  ...
[11:05] <astropirate> saste, forgive my stupid question.. but should I save it to a file via gst-launch and then read it with ffmpeg?
[11:05] <saste> astropirate: don't know how to use gst-launch, but you can read a pipe from ffmpeg
[11:05] <saste> check the pipe protocol, maybe there is a more clever way, dunno
[11:06] <astropirate> ok, thanks for your help
[11:35] <burek> rohankasat, check how does ffmpeg do it in the source code
[11:36] <burek> johnbender http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20speed%20up%20/%20slow%20down%20a%20video
[11:37] <burek> oh, johnbender, you don't need setpts in that case
[11:37] <burek> try reading about -async -isync and -vsync
[11:38] <burek> also this might help http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20grab%20the%20desktop%20(screen)%20with%20FFmpeg
[11:41] <astropirate> I am trying to record my desktop but also merge audio form an audio file into the recording
[11:41] <astropirate> I am doing this ffmpeg -f alsa -i output.mp3 -f x11grab -r 25 -s 1280x720 -i :0 -vn -acodec flac -vcodec libx264 -preset ultrafast -threads 0 video.mkv
[11:41] <astropirate> but it gives me this error:
[11:41] <astropirate> [alsa @ 0x110ce20] cannot open audio device output.mp3 (No such file or directory)
[12:27] <dougle> i'm setting profile:v to baseline for converting one png to a 5 second segment but i keep getting the x264 error "baseline profile doesn't support 4:4:4" anyone know how i can get away from it?
[12:29] <burek> astropirate, what's the point of this statement "ffmpeg -f alsa -i output.mp3" ?
[12:30] <astropirate> burek, to read the file
[12:30] <burek> remove -f alsa
[12:31] <burek> can you please use pastebin.com, to show your command line and its output?
[12:32] <burek> dougle*
[12:32] <astropirate> burek, I am in your debt sir/ma'am
[12:32] <burek> astropirate :beer: :)
[12:33] <burek> dougle can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[12:39] <dougle> burek: https://gist.github.com/3181423
[12:39] <dougle> (i think i owe you a keg by now burek)
[12:41] <astropirate> here is another dumb question:
[12:42] <madsy> I have a game emulator I'd like to screen capture with ffmpeg and its x11grab interface. But when I run the emulator in fullscreen it takes a fast YUV path with XVideo, so due to the hardware overlay, ffmpeg has nothing to copy. Is there a workaround?
[12:42] <astropirate> ffmpeg stps the x11 grab when the music is finished. how do i make it just use silence :) untill the x11 grab is finished?
[12:42] <burek> dougle try -profile:v instead of -profile
[12:43] <burek> astropirate, why don't you first grab what you need with x11grab and when you finish, just add the audio to it
[12:44] <burek> madsy, most emulators have an option to take a screenshot
[12:44] <burek> try reading its manual for it
[12:44] <astropirate> burek, because.. i'm doing a hack. system audio grab with ffmpeg sucks... lots of static. so i am using gst-launch to capture the audio
[12:44] <astropirate> it saves it to file and ffmpeg reads it
[12:44] <madsy> burek: pcsx-r does not have anything like that. Besides, I want video not still frames.
[12:45] <burek> astropirate, then don't use the mp3 file, use the pipe for audio
[12:45] <burek> so it won't end
[12:45] <astropirate> burek, YES!! :D how do I do that/
[12:45] <burek> btw, astropirate what command did you use when you tried "system audio grab" :)
[12:45] <astropirate> i tried figuring that out but couldn't figure out how to do it
[12:46] <astropirate> gst-launch -e pulsesrc device="alsa_output.pci-0000_00_1b.0.analog-stereo.monitor" ! audioconvert ! lamemp3enc target=1 bitrate=128 cbr=true ! filesink location=output.mp3
[12:46] <dougle> same result, just no deprecation message
[12:46] <astropirate> OHHH
[12:46] <astropirate> sorry i misunderstood burek sec let me find out
[12:47] <burek> ffmpeg -y -loop 1 -threads 0 -i input_image.png -f pcm_s16le -i -  ...
[12:47] <burek> some_script_that_produces_wav_output | ffmpeg -y -loop 1 -threads 0 -i input_image.png -f pcm_s16le -i -  ...
[12:47] <burek> the point is in "-i -"
[12:47] <burek> (and -f before it)
[12:48] <astropirate> i dont know if gst-launch will output audio to stdout
[12:48] <astropirate> :(
[12:48] <astropirate> for me to pipe it to ffmpeg
[12:49] <burek> madsy, it appears you can't do a screen capture in fullscreen, because the emulator is not using system video output, but draws directly using the display hardware
[12:49] <astropirate> ohh i think it does let me try it
[12:49] <burek> so, try capturing in non-fullscreen
[12:50] <burek> madsy, did you read this: http://www.linuxquestions.org/questions/linux-software-2/how-to-record-pcsx-game-play-to-video-file-943006/
[12:50] <burek> dougle, let me check
[12:51] <burek> dougle, x264 does not support that chroma format, so you might use filter to first change that and then to feed it to encoder
[12:52] <dougle> can you give me an example of such a filter
[12:53] <astropirate> burek, Unknown input format: 'pcm_s16le'
[12:53] <burek> dougle, try asking in #ffmpeg-devel, it's kinda advanced usage :)
[12:54] <burek> it should go something like ffmpeg -i input -vf "some_filter_for_chroma_conversion" -vcodec libx264 ...
[12:54] <burek> astropirate, just a asec
[12:55] <dougle> will do thanks burek, am currently reading the wiki
[12:56] <burek> astropirate can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[12:56] <burek> dougle :beer: :)
[12:58] <burek> oh pcm_s16le is a codec, not a format.. silly me :)
[12:58] <astropirate> :)
[12:59] <burek> astropirate, so, "-f u16le -acodec pcm_s16le -i -"
[12:59] <astropirate> so, where will ffmpeg output?
[12:59] <burek> or -f s16le
[12:59] <burek> im not sure now
[13:00] <burek> try this: some_script_that_produces_wav_output | ffmpeg -y -loop 1 -threads 0 -i input_image.png -f s16le -acodec pcm_s16le -i -  ... video.mkv
[13:01] <burek> where ... is all that -vcodec stuff and encoding options etc
[13:02] <astropirate> http://pastie.org/4335828
[13:02] <astropirate> :S
[13:04] <burek> you can't use -vcodec libx264 before -i
[13:05] <burek> it is treated as an input option
[13:05] <burek> so ffmpeg tries to read that -i as libx264 stream
[13:05] <burek> the order of params does matter
[13:05] <burek> ffmpeg <input options> -i input1 <input options> -i input2 ... <output options> output1 <output options> output2 ..
[13:06] <astropirate> ahh
[13:06] <burek> also, no point in using "-i -" if you dont send anything to ffmpeg through the pipe
[13:06] <astropirate> i am going to do that
[13:06] <burek> i.e. you need to have that gst before ffmpeg followed by a pipe
[13:06] <astropirate> i was just tyring to get the command right
[13:06] <burek> ok
[13:08] <burek> gst ... | ffmpeg -y -f x11grab -r 25 -s 1280x720 -i :0 -f s16le -acodec pcm_s16le -i - -acodec flac -vcodec libx264 -preset:v ultrafast -threads 0 video.mkv
[13:08] <burek> something like that
[13:08] <burek> but why not using just: ffmpeg -f x11grab -r 25 -s 1280x720 -i :0 -f alsa -i hw:0 -acodec flac -vcodec libx264 -preset:v ultrafast -threads 0 video.mkv
[13:09] <burek> like described here: http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20grab%20the%20desktop%20(screen)%20with%20FFmpeg
[13:09] <burek> and here http://ffmpeg.org/trac/ffmpeg/wiki/Capturing%20audio%20with%20FFmpeg%20and%20ALSA
[13:12] <astropirate> burek, because there is alot of static with that recording
[13:12] <astropirate> to get around it one has to go into alsamixer and set it to "record"
[13:12] <astropirate> then it becomes clear
[13:13] <astropirate> but i need to do everything programatically
[13:20] <burek> well you can
[13:20] <burek> there is amixer
[13:20] <burek> cmd line tool
[13:20] <burek> read its manual and see how to always first set your recording device
[13:20] <burek> and then fire up ffmpeg
[13:21] <burek> it's far easier than using gst and piping with ffmpeg and stuff
[13:22] <astropirate> HAHAH this failed soo bad
[13:24] <astropirate> (I'm working on an uber slick GUI front end for ffmpeg x11 capture and it looks so sexy you can lick it)
[13:52] <astropirate> burek, do you know if it is possible to change the x11 screen grab area while it is running?
[13:52] <astropirate> idk via sending messages?
[13:52] <astropirate> IPC? :S
[13:52] <astropirate> that would be killer
[13:53] <burek> I think not
[13:53] <burek> once the thread has been initialized and given those coordinates, it runs separately, so I guess not
[13:53] <burek> you might ask for a feature if you like :)
[13:53] <burek> or even better, provide a patch :)
[13:54] <astropirate> hahah i'm not that leet :p
[14:49] <sanfun> hi all. i'm having trouble compiling ffplay.exe and ffserver.exe on windows (mingw). is this expected?
[15:00] <sanfun> after all i managed to compile them, but ffmpeg.exe crashes when it should HTTP-stream to ffserver_g.exe .
[16:26] <fris> what would be the best variables for converting mp3 to ogg im currently just using -acodec libvorbis -ab 192k
[16:55] <stu> I am working on a project that is using ffmpeg to encode mp4. If I understand correctly, ffmpeg compiles with vdpau support by default. I only see flags to disable it when configuring. I have a nvidia GT 520 and have the ubuntu nvidia-currrent package installed. However, I am not seeing any decreases in decoding times. Can anybody give me some hints?
[16:57] <stu> *decreases in encoding times*
[17:07] <microchip_> stu: ffmpeg doesn't do GPU encoding ;)
[17:13] <microchip_> stu: vdpau is only used for decoding, eg ffh264vdpau decoder
[17:14] <roxlu_> hi!
[17:14] <microchip_> hi
[17:14] <roxlu_> I've asked this question in #libav too, but didn't get info there.. I hope someone in here can help me a bit further with this... all info is very welcome
[17:15] <roxlu_> I'm working on a project where I stream generated RGB24 images as h264/flv to a flash media server
[17:15] <roxlu_> this works all fine!
[17:15] <roxlu_> I want to add audio now
[17:15] <roxlu_> I'm wondering what approach I need to take to add this audio to the stream?
[17:22] <stu> microchip_: thanks
[17:27] <rexbron> Hey, Does anyone have any advice for copying a mov timcode track during a transcode?
[17:29] <burek> roxlu_ can you please use a pastebin site (like www.pastebin.com) to show your ffmpeg command and the complete console output?
[17:30] <burek> rexbron -c copy?
[17:30] <burek> or -map 0
[17:38] <roxlu_> burek: thanks, but I'm using the C library
[17:38] <rexbron> burek: I can't get it to copy it. I can post the ffprobe if you would like
[17:38] <roxlu_> burek: I'm happy to paste my code if you can help me with that
[17:39] <rexbron> burek: http://pastebin.com/zGphuBxZ
[17:39] <bwalker8981> Hi, I'm trying to install xuggler on top of ffmpeg, but the build keeps failing and saying "buildhelper.xml:1127: exec returned: 1". Does anyone know what I am doing wrong? Or does anyone have any experience with installing xuggler?
[17:55] <rexbron> ok figured it out
[17:55] <rexbron> needed to add a -dcodec copy and -map
[18:06] <maker> Hello, I was interested in the Summer of Code in Space program, in particoular to the libavfilter project. Is saste, or any other backup mentor going to join before the deadline?
[18:34] <burek> rexbron it seems its unsupported..
[18:34] <burek> roxlu_ did you check ffmpeg source code to see how it does that?
[18:35] <burek> so you can copy/paste the logic?
[18:35] <burek> maker, ask in #ffmpeg-devel
[18:35] <burek> bwalker8981, ask in xuggler support channel?
[18:39] <bwalker8981> burek: the #xuggler chat room has been empty for a very long time (I've never actually seen anyone in the chat), so I was hoping the ffmpeg group might have some advice
[18:41] <maker> burek: ty
[18:41] <burek> bwalker8981, ffmpeg has got nothing to do with xuggler
[18:42] <burek> the error you are trying to solve is xuggler's error, not ffmpeg's
[18:43] <burek> btw, why are you not using JNI to connect your java with ffmpeg, why using xuggler?
[18:44] <bwalker8981> burek: Xuggler uses FFmpeg to compress and uncompress media, and is built on top of it. I agree though, this is a xuggler error. There is very little xuggler documentation out there, so I'm trying to find someone who can help.
[18:45] <bwalker8981> burek: my goal is to get a rtmp stream sent to red5 media server, and I have only found that xuggler built on top of ffmpeg can do it. Do you know of another program that can send rtmp streams to red5?
[18:45] <burek> why do you use xuggler?
[18:45] <burek> why not ffmpeg alone?
[18:46] <bwalker8981> burek: i did not think that ffmpeg had native rtmp support. Does it?
[18:46] <burek> of course it does
[18:46] <burek> at least through librtmp
[18:46] <burek> or something
[18:47] <burek> download latest ffmpeg source code and type ./configure --help
[18:47] <burek> search for rtmp
[18:47] <bwalker8981> burek: k ill try it now
[18:47] <burek> --enable-librtmp         enable RTMP[E] support via librtmp
[18:47] <burek> it does
[18:47] <burek> are you on linux/win?
[18:49] <bwalker8981> burek: im on rhel
[18:50] <burek> well i never used it, but on debian/ubuntu you would just apt-get install librtmp-dev
[18:50] <burek> i dont know how do you do that on rhel
[18:50] <burek> when you install librtmp-dev, then compile ffmpeg with --enable-rtmp and you have it all
[18:52] <bwalker8981> burek: k, I already installed ffmpeg via yum, does that mean i need to uninstall it and then compile after installing lirtmp-dev?
[18:53] <burek> well, check first
[18:53] <burek> type ffmpeg -formats | grep rtmp
[18:53] <bwalker8981> burek: k
[18:53] <burek> no, ffmpeg -codecs rtmp
[18:53] <burek> o man
[18:53] <burek> ffmpeg -codecs | grep -i rtmp
[18:53] <burek> that :)
[18:54] <bwalker8981> burek: okay, ill try that, im wating for the install on librtmp
[18:56] <bwalker8981> burek: here is the output of the ffmpeg codecs: http://pastebin.com/kFWubaAu, does this look correct?
[19:01] <burek> bwalker8981 uninstall it
[19:01] <bwalker8981> burek: k
[19:01] <burek> and compile ffmpeg, after you install librtmp-dev
[19:38] <bwalker8981> burek: sorry this is taking so long, im having trouble installing git on rhel, so i haven't gotten the latest ffmpeg version yet
[19:44] <delicado> hi what functions can i use to make rewind a video decoding that reached an EOF. ?
[19:44] <delicado> hi what functions can i use to rewind a video decoding that reached an EOF. ?
[19:58] <delicado> how many here are chinese?
[20:11] <bwalker8981> burek: I don't understand how to run the ./configure command with the correct options. It tells me the options are not correct. see http://pastebin.com/Cc7LzviW   What am I doing wrong?
[20:12] <burek> why on earth would you enable all that bwalker8981?
[20:12] <microchip_> Unknown option "--enable-liba52"
[20:13] <burek> and the error itself is pretty self-explanatory
[20:13] <bwalker8981> burek: ha, well I guess I don't know what I'm supposed to enable, and I found instructions online saying to do that
[20:13] <bwalker8981> burek: k ill try with just the rtmp enable
[20:13] <burek> what exactly do you want to do with ffmpeg?
[20:13] <burek> what is the use case
[20:14] <bwalker8981> burek: create a live video stream from my computer to a red5 media server.
[20:14] <burek> live video encoded with what codec?
[20:14] <burek> and what codec to use for audio?
[20:14] <bwalker8981> burek: rtmp
[20:14] <bwalker8981> burek: flv
[20:14] <burek> ok, what about audio?
[20:16] <bwalker8981> burek: doesn't matter I guess? Whatever is easiest. The video is more important. we are trying to create an autonomous blimp that flies around our building, with a live video stream onboard.
[20:16] <burek> ok
[20:16] <burek> then you only need librtmp
[20:16] <burek> so
[20:16] <burek> ./configure --enable-librtmp
[20:16] <burek> and that's all
[20:17] <burek> after that, if everything goes ok, do: make
[20:17] <burek> and then: make install
[20:17] <bwalker8981> it says that it's an unknown option again... hmmm
[20:17] <burek> librtmp?
[20:17] <bwalker8981> oh sorry, i did rtmp
[20:17] <burek> are you doing the configure in the ffmpeg source directory
[20:18] <bwalker8981> now it didn't complain about the enable librtmp, but is said that yasm is not found
[20:18] <burek> yasm is small
[20:18] <burek> and powerful
[20:18] <burek> so it would be wise
[20:18] <burek> to download the source code
[20:18] <burek> and just type: ./configure && make && make install
[20:18] <burek> it will finish in less than a minute
[20:19] <bwalker8981> k, do you know where to get it?
[20:20] <bwalker8981> nvm found it
[20:24] <bwalker8981> does yasm need to be installed within the ffmpeg directory? I installed it in my home directory, and adjusted $PATH, but the ./configure still can't find yasm for some reason
[20:25] <burek> ?
[20:25] <burek> you don't have to do that
[20:25] <burek> I don't know how did you install it
[20:26] <burek> but if you compile it, it works
[20:26] <bwalker8981> http://pastebin.com/kjHnbBHa
[20:26] <burek> also, sometimes you need ldconfig
[20:26] <burek> are you root
[20:26] <burek> to do make install
[20:28] <bwalker8981> burek: yes, I'm root, and the make install didn't show any errors i don't think
[20:29] <burek> then just ldconfig
[20:29] <burek> and continue with ffmpeg
[20:40] <bwalker8981> burek: the configure worked now, i'm waiting on make to finish.
[20:43] <burek> ok
[20:53] <bwalker8981> burek: thanks. I've got it installed now, and it saws it supports rtmp. now i just need to figure out how to send a stream to red5...
[20:54] <burek> what is your input
[20:54] <burek> where from do you take it
[20:55] <bwalker8981> burek: im not really sure where to start now. i have a webcam, but i have no idea how to get ffmpeg to take the video from the webcam...
[20:56] <burek> search for grabbing/capture
[20:56] <bwalker8981> burek: fflogger: k ill take a look now
[21:24] <mikmu> Hey there,  I'm capturing a stream from an ip camera and I want to stream it out via http via ffserver or vlc.  I've tried both ffserver and vlc and the problem I'm having is that the client player always waits for the complete file to finish downloading before starting playback, instead of progressive download streaming
[21:25] <mikmu> I'm transcoding to h264, are there any sort of headers or keyframes, etc that I have to add?  Both programs are complaining that the stream does not provide global headers but that my output container requires them.  Is this the issue?
[21:40] <bwalker8981> burek: so i've run into a problem, i realized that my webcam was connected to my ubuntu computer (oops) so now im trying to install librtmp-dev on ubuntu. However, apt-get install librtmp-dev fails because it can't find the package. Do you know what to do?
[21:44] <relaxed> bwalker8981: apt-cache search librtmp
[21:45] <bwalker8981> relaxed: that pulls up librtmp0, but not librtmp-dev. I am trying to get rtmp support for ffmpeg on ubuntu now, and i thought i needed librtmp-dev installed. Wil librtmp0 also work?
[21:51] <burek> librtmp-dev - toolkit for RTMP streams (development files)
[21:51] <burek> you're doing something wrong bwalker8981 :)
[21:52] <burek> try apt-cache search rtmp | grep -i dev
[21:52] <bwalker8981> burek: lol yeah i know. that command produced no results
[21:53] <bwalker8981> burek: synaptic package manager also cannot find librtmp-dev
[21:53] <burek> which version of ubuntu are you using
[21:53] <bwalker8981> burek: 10.04
[21:53] <burek> hm, ok
[21:53] <burek> then you need to compile it from source :D
[21:54] <burek> or update your ubuntu to 11.x
[21:55] <bwalker8981> burek: hmmm... compiling from source would probably be an easier option. I tried installing it from source, but I just kept running into a million dependency issues
[22:00] <bwalker8981> burek: im trying again...
[22:01] <burek> ok
[23:02] <Snaggle> Is the fate server down?
[23:05] <saste> Snaggle: so it seems...
[23:17] <bwalker8981> burek: it looks like 10.04 does not have multiarch support (for librtmp0), so I need to upgrade ubuntu. Just curious, have you ever done this before? Should I be worried about losing programs if I upgrade to 12.04? I've never done it before
[23:27] <d4forze> ffmpeg > libav
