[00:00:08 CEST] <llogan> sorry, no. i don't use ffserver. you may get an answer on ffmpeg-user mailing list, but i wouldn't be too hopeful
[00:01:48 CEST] <llogan> i assume you already saw the docs and wiki examples?
[00:01:55 CEST] <llogan> https://trac.ffmpeg.org/wiki/Streaming%20media%20with%20ffserver
[00:07:59 CEST] <Exagone313> yes, i used this example
[00:08:07 CEST] <Exagone313> and it does not work for me
[00:08:42 CEST] <Exagone313> I don't like the mailing lists, what forum can I use?
[00:08:53 CEST] <Exagone313> stackoverflow/other?
[00:09:34 CEST] <llogan> no. stack overflow is only for programming questions. you could try super user, or Gman or Nabble for a "forum" interface to the mailing list
[00:09:43 CEST] <llogan> dir.gmane.org/gmane.comp.video.ffmpeg.user
[00:09:48 CEST] <llogan> http://ffmpeg-users.933282.n4.nabble.com/
[00:10:31 CEST] <llogan> not many ffserver answerers out there
[00:12:13 CEST] <Exagone313> ok i'll try this link
[00:12:36 CEST] <llogan> ping me when you send the message and i'll approve it in moderation queue
[00:13:03 CEST] <Exagone313> no encryption? sorry i don't
[00:13:09 CEST] <llogan> or wait 12-24 hours for me to go though the daily rounds
[00:13:19 CEST] <Exagone313> or ok i generate a password
[00:13:42 CEST] <llogan> what i meant was messages sent from unsubscribed users to the mailing list must be manually approved. this includes messages from nabble.
[00:16:00 CEST] <Exagone313> ok i see
[00:17:28 CEST] <Exagone313> I add my cfg directly here or I use a paste?
[00:17:51 CEST] <llogan> provide all info in the email
[00:18:37 CEST] <llogan> make it easy for the readers, unlike your previous paste.
[00:18:59 CEST] <llogan> provide the command then the complete output. not command1 command2 command3 output1 output2 output3
[00:19:13 CEST] <Exagone313> I have to subscribe to the mailing list?
[00:19:19 CEST] <llogan> no
[00:19:55 CEST] <llogan> but then you'll have to keep checking periodically to see if you get a reply (unless nabble tells you somehow; i don't really know what nabble does)
[00:20:29 CEST] <Exagone313> i prefer this way
[00:20:58 CEST] <Exagone313> i remember a post on launchpad for a bug on ubuntu, without a possibility to unsubscribe to the mailing list so i banned the email
[00:21:19 CEST] <llogan> launchpad sucks.
[00:22:02 CEST] <Exagone313> and i see lots of mailing list with emails... the bots say thanks to it
[00:23:29 CEST] <llogan> i've never recieved any spam from the single use, random, unique accounts i've used to test any potential spam load from sending to the ML
[00:24:23 CEST] <Exagone313> just, this command seems good? ffmpeg -i rtmp://127.0.0.1/live/stream http://127.0.0.1:8182/ogg.ffm|http://127.0.0.1:8182/webm.ffm
[00:24:43 CEST] <llogan> i don't know
[00:24:51 CEST] <Exagone313> ok
[00:26:46 CEST] <Exagone313> sound not ...
[00:26:47 CEST] <Exagone313> ./ffmpeg.sh: line 2: http://127.0.0.1:8182/webm.ffm: No such file or directory
[00:28:03 CEST] <Exagone313> lol it worked for 2 seconds
[00:28:05 CEST] <Exagone313> I think
[00:30:53 CEST] <pzich> Exagone313: does it work if you add -re ?
[00:31:50 CEST] <Exagone313> where?
[00:34:12 CEST] <Exagone313> pzich:
[00:34:29 CEST] <pzich> `ffmpeg -re -i rtmp://...`
[00:34:46 CEST] <Exagone313> with | ?
[00:39:18 CEST] <Exagone313> pzich: the | definitely not work so i tried ffmpeg -re -i rtmp://127.0.0.1/live/stream http://127.0.0.1:8182/ogg.ffm -i rtmp://127.0.0.1/live/stream http://127.0.0.1:8182/webm.ffm
[00:39:26 CEST] <Exagone313> (with and without the -re)
[00:39:57 CEST] <Exagone313> apparently, the -re make it works for 2-3 seconds, mroe often, but it stills fail with conneciton reste by peer
[00:45:04 CEST] <Exagone313> llogan: http://ffmpeg-users.933282.n4.nabble.com/Local-RTMP-to-live-stream-http-webm-ogg-with-ffserver-td4671197.html
[00:50:46 CEST] <llogan> approved, but you forgot to include the command, console output, and ffserver conf
[00:51:32 CEST] <Exagone313> i did
[00:52:25 CEST] <Exagone313> you don't see it?
[00:52:50 CEST] <llogan> https://ffmpeg.org/pipermail/ffmpeg-user/2015-June/027299.html
[00:52:59 CEST] <llogan> that's what my client also sees
[00:53:59 CEST] <llogan> i wonder if the commands and outputs were not included in the text/plain component of your message
[00:54:34 CEST] <nashgul> this line doesn't streams and doesn't  record the audio: http://pastie.org/10260966
[00:55:27 CEST] <llogan> Exagone313: how did you compose the message?
[00:55:48 CEST] <Exagone313> can you copy or screen what you see?
[00:56:03 CEST] <Exagone313> what you said is in <raw> nodes
[00:56:53 CEST] <nashgul> the comand: http://pastie.org/10260966 , and the output: http://pastie.org/10260968
[00:56:54 CEST] <llogan> see the link i provided
[00:57:49 CEST] <llogan> nashgul: it's easier if the command and console output are in the same paste. not sure why the trend lately is to separate them
[00:58:00 CEST] <nashgul> ok ok
[01:00:19 CEST] <nashgul> http://pastie.org/10260977
[01:01:06 CEST] <llogan> anyone else getting popups at the nabble link? first popup ive seen in a very long time
[01:03:06 CEST] <Exagone313> I have ad blockers
[01:03:12 CEST] <Exagone313> and I did
[01:03:22 CEST] <Exagone313> i get one
[01:03:27 CEST] <llogan> annoying
[01:03:52 CEST] <llogan> nashgul: why are you using -vsync 2?
[01:04:23 CEST] <nashgul> llogan: i don't know, ffmpeg tells me i must use it
[01:05:44 CEST] <nashgul> the  problem is the split and the mapping, if i don't make split the webcam streams audio correctly
[01:06:07 CEST] <nashgul> well, the webcam has not audio, i use alsa input
[01:06:55 CEST] <llogan> you probably don't need split if you're not performing other filtering
[01:07:23 CEST] <nashgul> llogan: when i split correctly i'm going to apply some filters
[01:07:41 CEST] <nashgul> add a logo.png, scroll text, etc..
[01:10:07 CEST] <llogan> try the mailing list for that one.
[01:14:38 CEST] <Exagone313> llogan: can you make a screen? if you don't see my cmd/out/cfg i repost without the <raw>
[01:16:22 CEST] <llogan> Exagone313: the link i provided shows what i see
[01:16:45 CEST] <Exagone313> ok i didnt see
[01:16:47 CEST] <llogan> you never answered my question about how you make the message
[01:16:59 CEST] <Exagone313> ok i reply
[01:18:37 CEST] <Exagone313> can you validate my reply?
[01:19:09 CEST] <Exagone313> llogan: on your link my email is shown .......
[01:19:22 CEST] <llogan> message approved
[01:19:36 CEST] <Exagone313> thanks
[01:20:07 CEST] <llogan> your "email" is shown, but it is obfuscated
[01:20:20 CEST] <Exagone313> "at" is not obfuscated for me
[01:21:14 CEST] <llogan> no bot processes that
[01:22:17 CEST] <llogan> if they did i would have received messages to my test accounts
[01:22:36 CEST] <llogan> but it's been years and nothing appeared
[02:12:20 CEST] <Zamboney> hi, quick question.  i wanted to try encoding using nvenc, since ffmpeg supports since version 2.6. however the windows build linked from the download section of ffmpeg.org returns error 'unknown codec nvenc' when i try to use.  so the question, is the version on the download site 2.6 or higher and if not, where do you find it
[02:17:47 CEST] <Zamboney> or do i need to build it myself to have this functionality
[02:19:17 CEST] <c_14> You have to build it yourself.
[02:19:21 CEST] <c_14> Because of license incompatibilities.
[02:19:43 CEST] <Zamboney> yeah i was looking at the forum on the download site and was getting that impression.  ok, thanks
[10:04:54 CEST] <nashgul> hi, good morning, what's wrong with this: http://pastie.org/10261420 ?
[10:06:36 CEST] <nashgul> i'm trying to shoot the filter every 10 seconds, and when it's launched: store 't' in var '1', and then uses '1' to substract from the X position of the text, to make a right-left scroll
[10:07:35 CEST] <nashgul> umm i don't find clearly examples of 'using expressions evaluations'
[12:37:43 CEST] <Fjorgynn> Hey I'
[17:21:38 CEST] <sine0> why would you need to have a constant bitrate when encoding for example an audio clip
[17:21:52 CEST] <sine0> whats wrong with vbr in mp3
[17:23:13 CEST] <RobotsOnDrugs> early hardware mp3 players had issues with vbr
[17:23:23 CEST] <sine0> ok
[17:23:38 CEST] <RobotsOnDrugs> there is no reason not to use vbr today
[17:23:47 CEST] <sine0> ok nice, thats cleared that up for me then
[17:24:04 CEST] <sine0> so its more of a legacy option
[17:24:52 CEST] <RobotsOnDrugs> it's also useful for streaming if you have limited bandwidth
[17:25:06 CEST] <RobotsOnDrugs> but generally, yes
[17:36:14 CEST] <sine0> -codec:v none
[17:36:17 CEST] <sine0> is that correct syntax
[17:37:40 CEST] <sine0> well it works im badass
[19:55:22 CEST] <LigH> Hello.
[19:56:00 CEST] <LigH> Is enforcing a FourCC while multiplexing to AVI, using parameter -vtag, still supported at all?
[19:56:34 CEST] <c_14> Not sure why it shouldn't be, why?
[19:58:04 CEST] <LigH> Because after multiplexing from MPEG-4 ASP (*.m4v), created by xvid_encraw, into AVI, the AVI container uses the FourCC "FMP4", even though MeGUI tries to enforce FourCC "XVID".
[19:58:26 CEST] <LigH> Sample call: "E:\Programme\MeGUI\tools\ffmpeg\ffmpeg.exe" -y -i "*.m4v" -vcodec copy -vtag XVID -r 25 "*.avi"
[20:03:55 CEST] <c_14> Hmm, when you say "still supported" does that mean it used to work?
[20:04:47 CEST] <LigH> People keep reporting this solution, as if it worked once. I don't belong to the people who kept using this over years... ;)
[20:09:12 CEST] <LigH> It may work while converting, but apparently does not work while multiplexing only (-vcodec copy).
[20:26:59 CEST] <c_14> LigH: I tried it out on my system, can't get it to work either. If it used to work on some version, it's a regression. Otherwise it's a feature request.
[20:27:08 CEST] <c_14> Either way, you can open a corresponding issue on trac.
[20:30:37 CEST] <LigH> Will do so, thanks
[20:30:55 CEST] <LigH> \o
[22:23:07 CEST] <microcolonel> I'm trying to build a y4m from a sequence of PNGs, but ffmpeg is pretending the input sequence is 25fps even though I specified 60fps
[22:23:57 CEST] <microcolonel> ease up fella, I'm on it
[22:24:07 CEST] <microcolonel> ffmpeg -f image2 -start_number 20 -i ./rf_final/%04d.png -r 60 -pix_fmt yuv422p rf.y4m
[22:24:13 CEST] <microcolonel> is the command
[22:24:28 CEST] <c_14> ffmpeg -f image2 -start_number 20 -framerate 60 -i ./rf_final/%04d.png
[22:24:41 CEST] <c_14> You specified the output framerate, not the input framerate
[22:25:45 CEST] <microcolonel> hmm
[22:25:50 CEST] <microcolonel> so r works on output
[22:26:00 CEST] <microcolonel> but framerate, when you put it before -i, works on input
[22:26:03 CEST] <microcolonel> or are they equivalent?
[22:26:20 CEST] <microcolonel> this is deeply confusing.
[22:26:39 CEST] <microcolonel> also https://en.wikibooks.org/wiki/FFMPEG_An_Intermediate_Guide/image_sequence this is wrong I guess
[22:26:41 CEST] <c_14> r works on both, but if you put it after the input filename it works on the output, if you put it before the input filename it works on the input. -framerate is an option specific to the image2 demuxer. When using the image2 muxer/demuxer always use -framerate
[22:26:57 CEST] <c_14> yes, that is very wrong
[22:27:07 CEST] <c_14> https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images
[22:27:46 CEST] <microcolonel> maybe the title should be changed to "create a video slideshow or convert a sequence to a video"
[22:27:50 CEST] <microcolonel> I didn't want a slideshow :P
[22:28:27 CEST] <microcolonel> Anyway, thanks, c_14
[22:28:53 CEST] <c_14> Well, technically every video is a slideshow.
[22:28:55 CEST] <c_14> np
[22:30:46 CEST] <techtopia> is there someway i can use -t or -ss to encode to an i-frame
[22:31:00 CEST] <c_14> You want to extract an i-frame from a video?
[22:31:09 CEST] <techtopia> like if i did -t 60 is there someway to make it encode to the closest i-frame to 60 secons
[22:31:10 CEST] <techtopia> no
[22:31:32 CEST] <c_14> You want the video to end on an i-frame?
[22:31:37 CEST] <techtopia> i want to encode up to an iframe, then later encode from that iframe to another that is another 60 seconds ahead
[22:31:40 CEST] <techtopia> yeah
[22:32:01 CEST] <techtopia> like the source file is still being written as im encoding
[22:32:18 CEST] <techtopia> so can't do it all in one go, and if i don't cut on i-frames i get sync errors
[22:32:51 CEST] <c_14> ffmpeg -ss start -t end -no_accurate_seek -i filename out.mkv <- might do it
[22:32:58 CEST] <microcolonel> techtopia: you could try pausing the encoder process as you go
[22:33:03 CEST] <techtopia> thanks will run a test
[22:33:08 CEST] <techtopia> you can pause it?
[22:33:13 CEST] <techtopia> how?
[22:33:18 CEST] <microcolonel> in your terminal you can press C-z
[22:33:25 CEST] <microcolonel> should stop the process
[22:33:30 CEST] <techtopia> nice, will try that too :)
[22:33:31 CEST] <techtopia> thanks guys
[22:33:47 CEST] <microcolonel> enjoy :)
[22:56:30 CEST] <toriso> Hi, I'm coding a video, and I'm having a message past duration too large, anyone know what it means?
[22:58:15 CEST] <techtopia> can you post a log
[22:58:23 CEST] <techtopia> of your encoding line and the ffmpeg output
[22:58:26 CEST] <techtopia> pastebin it
[23:02:21 CEST] <toriso> techtopia, yes, http://pastebin.com/CgRHGiNE
[23:09:08 CEST] <toriso> techtopia: any idea?
[23:29:00 CEST] <toriso> I fixed it
