[00:10:00 CEST] <oscarpal> 8-)
[00:12:49 CEST] <antiatom> I want to cut off the beginning of a video witout transcoding using -ss but it requires -t switch
[00:13:05 CEST] <antiatom> But I want it to copy until the end of the file so what do I put for -t
[00:38:55 CEST] <cbsrobot> antiatom: -ss does not require -t switch
[02:04:07 CEST] <DrBenway> is there a public build somewhere of the libraries with x264 built in?
[02:04:09 CEST] <DrBenway> for windows
[02:05:52 CEST] <klaxa> yes, see: http://ffmpeg.zeranoe.com/builds/
[02:07:07 CEST] <klaxa> when you look at the bottom you can see what libraries are included in the builds (afaik)
[02:07:14 CEST] <DrBenway> i thought this build didn't include x264
[02:07:18 CEST] <DrBenway> ok
[02:07:27 CEST] <DrBenway> because im looking at the -dev build and it's not there
[02:07:31 CEST] <DrBenway> (for static at least)
[02:07:52 CEST] <DrBenway> and i sort of figured that using the .dll.a would result in something that didn't include x264 as well
[02:08:12 CEST] <DrBenway> but you're right... it's in the configure line
[03:09:13 CEST] <heoyea> how u fix this error? Invalid frame size: 640×480
[03:09:51 CEST] <heoyea> using the ipod touch commands http://develop.participatoryculture.org/index.php/ConversionMatrix
[03:16:08 CEST] <t4nk327> hello every body i have request
[03:17:04 CEST] <t4nk327> i m trying to develop the ffmpeg based video player
[03:17:43 CEST] <t4nk327> which will play four HD video with video synchronised
[03:18:23 CEST] <t4nk327> how efficient ffmpeeg will be?
[03:19:17 CEST] <t4nk327> anybody thr?
[03:21:46 CEST] <t4nk327> hello durandal_1707..
[03:27:33 CEST] <t4nk327> hi thr, i'm looking for ffmpeg capablity of handling four 1080p HD video decoding & re-scaling in stand alone app
[03:34:07 CEST] <klaxa> ffmpeg is probably as fast as it gets
[05:00:29 CEST] <firefish5000> Good day, I am trying to run ffmpeg x11grab pipe to mpv in the background. While my command works in the foreground, it dies instantly in the background.
[05:02:10 CEST] <firefish5000> ffmpeg -f x11grab -r 25 -s "$(xdpyinfo | grep 'dimensions' | awk '{print $2}' | head -n1 | tr -d '\n')" -i :0.0+0,0 -threads 0 -f rawvideo pipe:1 | mpv --no-cache --demuxer=rawvideo --demuxer-rawvideo-fps=125 --demuxer-rawvideo-mp-format=bgr0 --demuxer-rawvideo-codec=lavc:rawvideo --no-fs --geometry=840x270+1060+800 --force-window-position --x11-name 'ScreenCastPreview' --demuxer-rawvideo-w=${SIZE%%x*} --demuxer-rawvideo-h=${SIZE//
[05:02:10 CEST] <firefish5000> *x} /dev/stdin &
[05:02:11 CEST] <klaxa> how are you invoking it?
[05:02:37 CEST] <klaxa> shouldn't --demuxer-rawvideo-fps be 25?
[05:03:22 CEST] <klaxa> also you have to use -framerate instead of -r
[05:03:24 CEST] <firefish5000> Yes, though higher shouldn't hurt
[05:03:48 CEST] <klaxa> maybe using a container is easier?
[05:04:28 CEST] <klaxa> what errors do you get?
[05:05:32 CEST] <buu> Hey guys, I have what I'm pretty sure is an image file but when I run 'file' on it I get the following: 225682-2-f: MPEG ADTS, layer I, v2, Monaural
[05:05:46 CEST] <buu> Anyone seen something like this before?
[05:07:33 CEST] <grepper> buu: can imagemagick identify/display it?
[05:08:04 CEST] <buu> grepper: `identify` gives up on it
[05:08:10 CEST] <grepper> and ffmpeg ?
[05:08:17 CEST] <buu> errors detected in input
[05:08:27 CEST] <buu> 225682-2-f: Invalid data found when processing input
[05:08:54 CEST] <grepper> maybe if its corrupt that is part of the reason file gets confused
[05:09:12 CEST] <grepper> or maybe it really is adts
[05:10:02 CEST] <buu> I'm pretty sure it's not corrupt
[05:10:09 CEST] <firefish5000> klaxa, No clue on the errors. Nothing is bueing written, tried redirecting as well.
[05:10:46 CEST] <klaxa> when i try to run it SIZE is not set, is that different on your system?
[05:11:09 CEST] <klaxa> i'll replace it by the values of my system
[05:11:51 CEST] <firefish5000> sorry, my SIZE is set to 3360x1080.
[05:12:39 CEST] <klaxa> oh... hmm... it also doesn't work for me when i run it in the background
[05:13:04 CEST] <firefish5000> at least i'm not alone there..
[05:13:20 CEST] <klaxa> i can imagine that it's a shell issue
[05:13:46 CEST] <klaxa> maybe just running it in tmux or screen works around your problem?
[05:17:27 CEST] <firefish5000> zsh is giving 'suspended (tty output) zsh SCRIPT.sh', which is more helpfull
[05:21:59 CEST] <firefish5000> hmm, seems like that actually was the problem. must redirect the output before making it a bg process
[05:28:21 CEST] <firefish5000> Yep! Now, while im at it, are there any other suggestions before I finalize this part? I chose rawvideo because it removed noticable lag compared to mkv,mp4,vob,etc. and mpv fps was bumped (though not that much, earlier ffmpeg the x11grab was 60fps) to ensure playback stays with the latest frames.
[05:29:35 CEST] <Taniey> When I overlay a gif on video ,I get an unexpectedly result , the gif
[05:29:36 CEST] <Taniey> Flicker a little time before Predetermined time ;
[05:32:52 CEST] <Taniey> I command like : ffmpeg -y -i mainvideo.mkv -ignore_loop 0 -i gif.gif -filter_complex "overlay=x=182:y=82:shortest=1:repeatlast=0:enable=between(t\,49.560\,60)" outvideo.mp4
[05:35:31 CEST] <Taniey> how can I resolve this question?
[07:18:29 CEST] <nanoEng> can anyone help me resolve the follow compile error I am getting: http://pastebin.com/eqRkp0as ???
[07:18:51 CEST] <nanoEng> My configure settings are:

[07:22:40 CEST] <nanoEng> I am trying to modify and compile ffplay, to make a simple video player with custom features.
[07:23:03 CEST] <nanoEng> ffplay.exe should be a 64bit program.
[07:24:00 CEST] <nanoEng> Any one know why it is not recognizing 64-bit mode registers?
[07:42:07 CEST] <nanoEng> Also, when i try to go to http://ffmpeg.pastebin.com , I am redirected to simply http://pastebin.com

[08:10:01 CEST] <Taniey> ffmpeg question about overlay gif.
[08:10:03 CEST] <Taniey> before 48.560s e.g. : 48s ,the gif show a little time and disappearance, reach to 48.560s the gif normal display.
[08:10:31 CEST] <ln-> Taniey: please never do that again
[08:14:49 CEST] <nanoEng> Horray Taniey!! \('3')/ stick it to the man!
[08:16:16 CEST] <Taniey> I am very sorry ,i am
[08:16:16 CEST] <Taniey> not intentional
[08:18:05 CEST] <nanoEng> Taniey, you should use http://pastebin.com so that it is easier for the people here to ignore you.
[08:20:50 CEST] <Taniey> thanks very much, I will try it.
[08:24:58 CEST] <Taniey> I paste the information to http://pastebin.com/Eny8Nbvx, can Anybody help me ?
[08:29:00 CEST] <nanoEng> I cannot :\ i am idiot
[08:29:27 CEST] <nanoEng> What is your problem? You said something about .gif images?
[08:30:36 CEST] <Taniey> yes ,ffmpeg about overlay gif
[08:35:45 CEST] <nanoEng> hmm, I am here because I am having erros compiling ffplay
[08:36:03 CEST] <nanoEng> http://pastebin.com/eqRkp0as
[08:40:11 CEST] <buu> nanoEng: is this on windows?
[08:40:12 CEST] <Taniey> About ffplay, I rarely use, I am very sorry about I can not help you .
[08:41:20 CEST] <SteamPoweredH> ffmuffplay
[08:42:48 CEST] <buu> Taniey: You tell ffmpeg to only overlay the gif between 48.560 and 60 right?
[08:43:10 CEST] <Taniey> yes
[08:43:35 CEST] <buu> Taniey: So what is the issue before that?
[08:43:38 CEST] <Taniey> I use enable Parameters
[08:44:08 CEST] <Taniey> before 48.560s e.g. : 48s ,the gif show a little time and disappearance, reach to 48.560s the gif normal display.
[08:45:55 CEST] <buu> Taniey: But it's not supposed to display?
[08:46:02 CEST] <buu> I can't understand what you're asking sorry
[08:47:00 CEST] <Taniey> I am Sad ,my English is Pool.
[08:48:37 CEST] <Taniey> I can`t clearly Expression
[08:48:44 CEST] <Taniey> my idea
[08:52:59 CEST] <Taniey> I just think this situation can`t Happen,but ,I play the result ,It just like my said
[08:57:15 CEST] <Taniey> when the gif have two or more pic, this situation will happen . When the gif fps the litter the obviouslier.
[09:00:21 CEST] <Taniey> <buu> I can gave you the gif sample.
[09:03:04 CEST] <nanoEng> Taniey: Try http://translate.google.com ? :p
[09:04:58 CEST] <Taniey> I am using http://translate.google.com ~~
[09:05:19 CEST] <Taniey> but Is`s slow.
[09:17:04 CEST] <nanoEng> oh :\
[09:23:35 CEST] <c_14> Taniey: could you upload your gif sample?
[09:23:46 CEST] <c_14> I tried your command with some files I have and it seems to work as intended.
[09:24:24 CEST] <Taniey> yes ,I can.
[09:26:58 CEST] <Taniey> c_14 : I send the gif to you . but it show waiting.
[09:27:30 CEST] <buu> Taniey: Try uploading it someplace
[09:27:34 CEST] <buu> Taniey: to a website
[09:28:11 CEST] <c_14> Something like datafilehost is preferred because you get a direct download link
[09:32:50 CEST] <nanoEng> imageshack?
[09:46:31 CEST] <Taniey> ok
[09:50:47 CEST] <Taniey> gave me an email , I send email to you.
[09:55:23 CEST] <c_14> Taniey: I sent you a pm with my email
[12:41:22 CEST] <cbreak> I just compiled ffmpeg
[12:41:45 CEST] <cbreak> and in /usr/local/lib/pkgconfig/libavformat.pc, the Libs line also contains -Wl,-framework,Security
[12:42:02 CEST] <cbreak> why not -framework Security like all the other frameworks?
[14:19:32 CEST] <termos> I'm transcoding some flv h264+aac to an rtmp endpoint, and the video takes about 8 seconds to start in the player. Are there known or common reasons for this?
[14:21:14 CEST] <BtbN> if your goplength is long, it can take a while before an I-Frame reaches a client
[14:40:35 CEST] <termos> hm that's a good point, gop length is 3s
[14:51:14 CEST] <BtbN> so it should take at most 3 seconds before it can start playing after receiving the stream
[15:26:20 CEST] <termos> it doesn't seem to have an effect, but the start up delay does not happen when I push to wowza only when I push to Akamai
[15:26:58 CEST] <termos> so the problem might be on their end, could be the result of something they're doing inside their CDN
[15:57:57 CEST] <ScottSteiner-> how can i list devices available for a selected input? trying to record system audio but cant get it to work with hw:0
[15:59:28 CEST] <claz> how can i split video such that the last few frames and the first few frames of adjacent segments don't overlap?
[15:59:42 CEST] <claz> i need to concat them afterwards and it's not fluid..
[16:00:37 CEST] <claz> -f segment works but i need variable size segments
[18:59:32 CEST] <Stil> Hi.
[18:59:39 CEST] <Stil> Perhabps sb. can help me :
[18:59:46 CEST] <Stil> I have the folowing problem :
[18:59:52 CEST] <BigFeet> Hey guys, I just discovered ffmpeg and I'm wondering if I can use it to get live tv to my FireTV using h.264 instead of mpeg2. Mpeg2 has interlacing probs
[19:01:27 CEST] <Stil> I have a Videofile C:\gamerecord.avi and an sound C:\Input.wav and want's to combine them to H265 For Youtube. Is there an option , to let only play the gamesound with 50 % ? Can you give me the whole command for this output?
[19:01:33 CEST] <Stil> Thanks for your hep
[19:01:35 CEST] <Stil> Thanks for your help
[19:13:25 CEST] <Stil> I have a Videofile C:\gamerecord.avi and an sound C:\Input.wav and want's to combine them to H265 For Youtube. Is there an option , to let only play the gamesound with 50 % ? Can you give me the whole command for this output?
[19:13:27 CEST] <Stil> Thanks for your help
[19:16:42 CEST] <DHE> BigFeet: maybe. if your content is interlaced, you should either deinterlace it (-vf yadif is recommended these days) or specify it as interlaced during processing (-flags ildct for h264)
[19:17:02 CEST] <occupant> That might be possible, but you could always just reduce the volume in Audacity or something.
[19:18:46 CEST] <klaxa> there is also the volume filter
[19:19:17 CEST] <klaxa> see: https://ffmpeg.org/ffmpeg-filters.html#volume
[19:20:34 CEST] <Nolski> Stil: There's also amerge
[19:20:36 CEST] <Nolski> http://www.ffmpeg.org/ffmpeg-filters.html#amerge-1
[19:21:43 CEST] <pzich> I think he'd want amix, not amerge
[19:23:33 CEST] <Nolski> pzich: doesn't amix not support modifying volume?
[19:24:18 CEST] <pzich> I don't think amerge does either, but I think amerge is for adding more channels to an audio stream vs mixing them together
[19:24:31 CEST] <Stil> ok.
[19:24:50 CEST] <Stil> And this H265 , Must there be something imported ?
[19:24:53 CEST] <Stil> Or just
[19:24:58 CEST] <occupant> and this kinda thing is meant for workflows where you know what you're dealing with. if you're making a one-off video, you might be better off adjusting the audio by hand still.
[19:25:27 CEST] <occupant> otherwise there's potentially a lot of encode -> tweak -> encode
[19:25:46 CEST] <Stil> ffmpeg -i input.avi -f h265 output.mp4
[19:26:12 CEST] <occupant> true, true
[19:26:26 CEST] <Stil> so , ffmpeg -i input.avi -tweak -f h265 output.mp4 ?
[19:27:09 CEST] <Stil> ?
[22:12:02 CEST] <ollehippe> hi, could anyone enlighten me on how to interpret this ffmpeg output:
[22:12:05 CEST] <ollehippe> Stream map '0:v:0' matches no streams.
[22:12:05 CEST] <ollehippe> To ignore this, add a trailing '?' to the map.
[22:13:08 CEST] <c_14> The input file has no video screen, since you specified that you wanted the first video stream ffmpeg errors out. If you don't want ffmpeg to error out because of it, you can add a ? to the end of the map (useful for scripts and stuff).
[22:15:21 CEST] <ollehippe> c_14: yep, I just cannot find out where the question mark belongs to. I have a bunch of FLACs, some having coverart and some don't. I am trying the following, to extract metadata, the coverart if present, and reencode it into aac:
[22:15:45 CEST] <ChocolateArmpits> the covert art is not a video stream
[22:16:00 CEST] <ChocolateArmpits> unless it's literally a video
[22:16:05 CEST] <ChocolateArmpits> which I doubt at this point
[22:16:36 CEST] <ollehippe> ffmpeg -i source.flac -f ffmetadata tmpdir/metadata -map 0:v:0 -c:0:v copy -vsync 2 -f image2 tmpdir/coverart -map 0:0 -c:0:a libfdk_aac -vbr 3 -f mp4 tmpdir/target.m4a
[22:17:31 CEST] <ollehippe> this works fine if for flac having coverart, but flacs w/o issue the warning
[22:18:21 CEST] <c_14> ChocolateArmpits: ffmpeg interprets cover art as a video stream
[22:18:30 CEST] <c_14> ollehippe: -map 0:v:0?
[22:19:05 CEST] <ChocolateArmpits> c_14: isn't that...unorthodox ?
[22:19:09 CEST] <ollehippe> c_14: input 0, type video, first stream
[22:19:55 CEST] <ollehippe> c_14: not necessary in this case, but should be fine
[22:19:59 CEST] <c_14> ChocolateArmpits: Want to write the "correct" implementation?
[22:20:09 CEST] Action: ChocolateArmpits shakes head
[22:20:37 CEST] <ollehippe> :)
[22:21:25 CEST] <ollehippe> so I've tried 0:v:0? and everything, but the best I got was "Output file #1 does not contain any stream"
[22:21:54 CEST] <ollehippe> ...resulting I neither a metadata file, nor the target.m4a
[22:22:02 CEST] <c_14> Ah
[22:22:04 CEST] <c_14> hmm
[22:24:12 CEST] <c_14> I see 2 options, split that command into two commands (one for each output), or put it in a script and ffprobe the input to find out if it has a video stream or not and then run a command with/without the image output. (You could also write a patch to add an option to ignore empty outputs)
[22:25:10 CEST] <ollehippe> c_14: I want to extract metadata, (coverart) and reencode in one step. In a second step I want to check whether the coverart file exists, and if yes add it to target.m4a via atomicparsley, and if not add a differnt file
[22:26:43 CEST] <ollehippe> c_14: yep, this would be fine, I was just wandering what the "add a trailing '?' to the map" does. I thought if it was added to the mapping processing of a non-exiting stream would be skipped
[22:26:59 CEST] <ollehippe> /wan/won/
[22:27:43 CEST] <ollehippe> ..which I hoped would lead to an extracted metadata file and the reencoded audio stream
[22:34:15 CEST] <ollehippe> this is btw ffmpeg version git-2015-08-16-767d780
[22:43:33 CEST] <c_14> The non-existing stream is skipped, but ffmpeg errors out if it notices that one of the output files doesn't have any streams.
[22:46:00 CEST] <ollehippe> c_14: so the question mark would be used this way: "-map 0:v:0?" ?
[22:46:46 CEST] <Juli__> Hey all, i could need some help with ffmpeg, i just compiled it for my raspberry pi and installed it aswell. No problems until now. But if i start streaming it starts for a short moment and stop with http://IP:8090/feed1.ffm: Connection timed out. Any idea ? Thanks for help allready.
[22:50:21 CEST] <c_14> ollehippe: afaik yes
[22:50:48 CEST] <c_14> Juli__: Sounds like a network problem
[22:50:56 CEST] <ollehippe> c_14: well then this is bad news :) I was hoping that I used the qeustion mark wrongly...
[22:53:26 CEST] <Juli__> Hm.. currently use a wifi connection and its the only network interface. In my ffmpeg.conf i set the ip of pi and the start file for stream is set with ip aswell.
[22:55:29 CEST] <c_14> Can you ping the host? Can you use netcat to connect to the port?
[22:55:43 CEST] <ollehippe> Juli__: does your Pi have to transcode the stream?
[22:56:26 CEST] <Juli__> oh i dont know. I followed like 20 tutorials on google to get some stuff to work. Im not that much into the pi/linux
[22:56:46 CEST] <ollehippe> i.e. what happens if you try to stream something of really really low quality
[22:57:10 CEST] <ollehippe> (like resolution of 300x200)
[22:58:21 CEST] <Juli__> i could try that. i used the default until now 640x480
[22:59:58 CEST] <ollehippe> Juli__: open a shell to your pi, start streaming, and watch the ffmepg process via /usr/bin/top.
[23:00:08 CEST] <Juli__> didnt work aswell :( here is what happend in console http://pastebin.com/d8Lqvcnd
[23:00:55 CEST] <ollehippe> 640x400 shouldn't be much of an issue as log as your Wifi is not 801.11b (which would be quite ancient for SOHO)
[23:02:16 CEST] <ollehippe> 36864 kb/s
[23:03:00 CEST] Last message repeated 1 time(s).
[23:03:08 CEST] <Juli__> Well ollehippe, it start the process and take about 30% cpu and after 10-20 sec it kills itself
[23:03:39 CEST] <ollehippe> Juli__: can you read what I write? I have strange colours for some reason
[23:03:54 CEST] <Juli__> yes
[23:04:04 CEST] <ollehippe> Juli__: what does it say about 36864kb/s ?
[23:04:23 CEST] <Juli__> to much ?
[23:04:43 CEST] <ollehippe> in order to stream with ~30MB/s yould need at least 802.11n
[23:04:58 CEST] <ollehippe> (I mean your wifi)
[23:05:04 CEST] <Juli__> how can i set it lower ?
[23:05:18 CEST] <ollehippe> I don't know
[23:05:27 CEST] <Juli__> in ffmpeg conf is set to MaxBandwidth 10000
[23:05:35 CEST] <Juli__> kbit/sec
[23:06:38 CEST] <ollehippe> have you triedstreaming over wire?
[23:09:15 CEST] <Juli__> not yet
[23:10:35 CEST] <ollehippe> Juli__: try it first, to exclude wifi problems
[23:10:46 CEST] <Juli__> i see what i can do
[23:12:04 CEST] <ollehippe> Juli__: I don't know your use case, but if you want to stream your home videos or something form a networked storage, I'd try plex. It sucks IMO, but is quite painless
[23:12:16 CEST] <heoyea> how u set the fonts?
[23:12:21 CEST] <heoyea> [Parsed_subtitles_0 @ 0x55d1c15934c0] fontconfig: cannot find font 'Arial', falling back to 'Nimbus Sans L'
[23:12:55 CEST] <ollehippe> Juli__: and there should be images for PI available
[23:14:06 CEST] <ollehippe> c_14: so dammit, I'll do it in two steps. Thanks for your help :)
[23:14:35 CEST] <Juli__> images ? for ffmpeg ?
[23:14:56 CEST] <c_14> heoyea: linux?
[23:15:10 CEST] <ollehippe> Juli__: nope, system image files (RasPlex)
[23:15:39 CEST] <heoyea> c_14: yea
[23:15:44 CEST] <Juli__> i got raspian
[23:16:19 CEST] <Juli__> btw, how can i answer you directly in irc ? like you do to me
[23:16:52 CEST] <c_14> heoyea: put the font files into ~/.fonts and then run `fc-cache -vf'
[23:16:58 CEST] <c_14> Or install the fonts via package management.
[23:17:10 CEST] <ollehippe> Just put nickname followed by a colon at the beginning of the line
[23:19:01 CEST] <pingouin> Hello everybody.
[23:21:36 CEST] <Juli__> ollehippe: okay i restarted the pi now with lan connection and will see what happend now
[23:22:00 CEST] <heoyea> Juli__: type the 1st few letters of the persons name and press tab
[23:22:18 CEST] <Juli__> heoyea: ah ^^
[23:22:33 CEST] <heoyea> c_14: Thanks i will give that a try, seems like i was missing the mscorefonts
[23:22:50 CEST] <ollehippe> Juli__: let's see...
[23:22:55 CEST] <heoyea> Juli__: pro now
[23:28:42 CEST] <heoyea> whats the flag to set the font size for hardcoded burn-in subtitles?
[23:29:24 CEST] <Juli__> ollehippe: Okay now on lan i get the exactly same problem
[23:32:56 CEST] <Juli__> ollehippe: i tried searching on google but nothing helpfull "to connection timed out" i can find. I even can't find something in the source file with "connection timed out" like this sentence doesn't exist
[23:37:01 CEST] <Juli__> ollehippe: i found out something interesting. If i use "ffmpeg -f video4linux2 -i /dev/video0 out.avi" just to but out an avi file and not stream it to a server it works
[23:38:14 CEST] <c_14> heoyea: either modify the subtitle file or use the force_style option for the subtitles filter
[23:38:45 CEST] <heoyea> c_14: does that work for srt files or only ass files?
[23:39:04 CEST] <c_14> All text subtitle formats
[23:39:32 CEST] <c_14> (ffmpeg represents text subtitles internally as ass)
[23:39:42 CEST] <ollehippe> Juli__: your output on pastebin says "rawvideo" and 36864 kb/s. IIRC, the PI has a 100mbit NIC, so this should not work (you can't put 30MB/s over FastEthernet)
[23:40:46 CEST] <ollehippe> Juli__: why do you stream rawvideo, why not something compressed?
[23:42:07 CEST] <Juli__> ollehippe: how can i use compressed ?
[23:43:22 CEST] <heoyea> c_14: can u give me an example of fontsize i dont see any flags for that in the sections http://ffmpeg.org/ffmpeg-filters.html#subtitles-1
[23:43:52 CEST] <ollehippe> Juli__: https://trac.ffmpeg.org/wiki/StreamingGuide
[23:44:13 CEST] <ollehippe> Juli__: I've never done this myself, so I don't know
[23:46:20 CEST] <c_14> heoyea: subtitles=sub.srt:force_style='Fontsize=9001'
[23:48:49 CEST] <Juli__> ollehippe: well okay thanks for help dude, i will try something arround
[23:49:59 CEST] <ollehippe> Juli__: yea, try one of the examples from the guide...
[23:59:06 CEST] <Juli__> ollehippe: i think i found the problem, its my webserver
