[00:07:53 CET] <Polochon_street> Hi! I know this is a hot issue, but I have some code that uses libswresample - which is not available for Ubuntu 14.04. It works on my platform, but someone that helps me can't compile the code (obviously, due to the lack of libswresample). He says that there's libavresample-dev available. What should I do? Switch to libavresample? Or is there a more « standard » way?
[00:14:48 CET] <Polochon_street> ... There don't seem to be any difference between libavresample and libswresample, besides the function prefixes? O_o
[00:16:38 CET] <durandal_1707> there is, lavr clips floats
[00:17:09 CET] <Polochon_street> (which means?)
[00:18:08 CET] <durandal_1707> you do not know?
[00:18:41 CET] <Polochon_street> no? It distords sound?
[00:18:57 CET] <durandal_1707> yes
[00:19:20 CET] <Polochon_street> is it really that bad? Is libavresample still developed?
[00:20:08 CET] <Polochon_street> I'm kind of lost, why are libsw/libav coexisting? Is it a side effect of libav/ffmpeg « war » ?
[00:24:14 CET] <furq> yes
[00:49:13 CET] <prelude2004c> can someone help me with vdpau ( nvidia ) decoding
[00:49:16 CET] <prelude2004c> how do i set that up
[00:50:40 CET] <prelude2004c> i have nothing in : Supported hwaccels:
[00:50:43 CET] <Hfuy> Hello.
[00:52:00 CET] <Hfuy> Would the following be a reasonable command for converting things to prores with current ffmpeg builds?
[00:52:01 CET] <Hfuy> ffmpeg -y -probesize 5000000 -i inputfile.mov -c:v prores_ks -profile:v 3 -qscale:v 11 -vendor ap10 -pix_fmt yuv422p10le -s 1920x1080 output.mov
[00:52:09 CET] <Hfuy> I mean, it seems to work.
[00:57:01 CET] <furq> prelude2004c: recompile with --enable-vdpau
[00:57:50 CET] <furq> and/or install libvdpau-dev
[01:01:17 CET] <Mantas_> Hi there! I was following MS tutorial on how to compile FFMPEG for WinRT https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT and used these commands http://pastebin.com/W69G8aZv. However, I got cl is unable to create an executable file. C compiler test failed.
[01:01:51 CET] <Mantas_> Any ideas what could be wrong?
[01:01:53 CET] <waressearcher2> Mantas_: hallo
[01:12:15 CET] <dongs> how does -to work with -ss ? because -ss start -to end doesn't trim the video between them
[01:12:26 CET] <dongs> i hate using -t because i have to calculate timestamp difference
[01:13:46 CET] <llogan> Hfuy: looks ok. not sure if qscale will do anything. might want to look into "-movflags +write_colr"
[01:17:08 CET] <llogan> dongs: are you using -ss as an input option?
[01:17:32 CET] <dongs> yeah
[01:17:40 CET] <dongs> i mean, -ss foo -t bar works fine
[01:17:51 CET] <dongs> but i have to calculate end-start and input it as t.
[01:18:02 CET] <dongs> i want to just do -ss start -to end
[01:24:38 CET] <llogan> dongs: https://trac.ffmpeg.org/wiki/Seeking#Cuttingsmallsections
[01:25:02 CET] Action: Hfuy listens to Faithless's "Insomnia"
[01:25:11 CET] <dongs> llogan: yes, that does not work
[01:25:25 CET] <dongs> oh i guess i need -copyts
[01:25:58 CET] <dongs> no the first example from tehre definitely does NOT work.
[01:26:06 CET] <dongs> it cuts from 1:00 to end of clip
[01:28:03 CET] <dongs> will try with -copyts and see
[01:29:48 CET] <dongs> ffmpeg -ss 10:00 -i "2015.12.02 LIVE.ts" -to 12:00 -c copy ff.ts
[01:29:51 CET] <dongs> made 12 minute long ff.ts
[01:29:53 CET] <dongs> ....
[01:30:05 CET] <dongs> -copyts made 0-byte file cuz it sait it was "empty"
[01:31:28 CET] <dongs> i see, -ss after -i makes it work as intended
[01:31:49 CET] <dongs> but 3rd case with -copyts doesnt work, oh well, at least the 2nd one does.
[01:34:23 CET] <c_14> Seems to work for me
[01:34:35 CET] <dongs> maybe depends on container type
[01:34:53 CET] <dongs> Output file is empty, nothing was encoded (check -ss / -t / -frames parameters i
[01:34:55 CET] <dongs> f used)
[01:35:05 CET] <dongs> ^ thats what it does w/same line as above and -copyts aded
[01:35:06 CET] <c_14> ffmpeg -y -ss '00:05:52.5' -i viedo.mkv -to 6:22.6 -c copy -copyts ~/out.mkv
[01:35:58 CET] <c_14> The listed duration in the container is off though
[01:36:02 CET] <c_14> For whatever reason
[01:39:35 CET] <Hfuy> How would I go about finding whether the version of ffmpeg I have is 32 or 64 bit?
[01:40:51 CET] <cbsrobot-> ^ dongs
[01:40:59 CET] <c_14> Hfuy: file `which ffmpeg`
[01:41:54 CET] <dongs> cbsrobot-: yes beacuse one line of output really needs to be on pastebin.
[01:42:16 CET] <cbsrobot-> dongs: ...  COMPLETE console output
[01:42:23 CET] <Hfuy> c_14: not on windows, I suspect
[01:42:33 CET] <c_14> ah, eh
[01:42:41 CET] <c_14> try right clicking and looking in properties?
[01:43:23 CET] <Hfuy> Not so far as I can see.
[01:43:33 CET] <dongs> cbsrobot-: http://bcas.tv/paste/results/2MxbNq14.html shruggin'
[01:44:23 CET] <cbsrobot-> dongs: Duration: 00:49:03.52, start: 3692.436200, bitrate: 9781 kb/s
[01:44:28 CET] <c_14> Hfuy: copy it to a unix machine and run file on it...
[01:44:29 CET] <dongs> yeah?
[01:44:38 CET] <cbsrobot-> your start ts is not 0
[01:45:02 CET] <dongs> it mostlikely never will be, with mpegts
[01:45:03 CET] <dongs> and?
[01:45:11 CET] <cbsrobot-> I guess that's why your output is wrong
[01:45:12 CET] <c_14> dongs: try adding -start_at_zero
[01:45:29 CET] <Hfuy> Ah. Yes. I have a bit-depth-incompatibility problem.
[01:45:32 CET] Action: Hfuy scratches his head
[01:45:46 CET] <dongs> c_14: nope, same result as w/o, 12minute long cut
[01:46:06 CET] <Hfuy> 64-bit ffmpeg can't talk to 32-bit avisynth
[01:46:06 CET] <c_14> dongs: with -copyts
[01:46:22 CET] <dongs> that worekd.
[01:46:32 CET] <cbsrobot-> \o/
[01:46:52 CET] <dongs> thanks.
[01:47:43 CET] <prelude2004c> hey can anyone help me with how to get -hwaccel vdpau for fmpeg
[01:48:05 CET] <c_14> compile with --enable-vdpau
[01:48:07 CET] <prelude2004c> i instaled the rpms and they are there. i compiled ffmpeg again and still shows no hardware accells available
[01:48:11 CET] <prelude2004c> yup did that
[01:49:29 CET] <prelude2004c> ./configure --enable-gpl --enable-nonfree --enable-nvenc --enable-pthreads --enable-libx264 --enable-debug --enable-static   --enable-vdpau  --enable-hwaccels
[01:49:33 CET] <prelude2004c> that is what i have been using
[01:55:04 CET] <Hfuy> Gaak. How do I make it do 16-bit PCM stereo sound?
[01:55:14 CET] <c_14> -c:a pcm_s16le
[01:55:25 CET] <Hfuy> Thanks.
[01:55:39 CET] <c_14> prelude2004c: seems to work for me (didn't try your exact configure line because I don't have the nvenc headers)
[01:56:01 CET] <c_14> In configure's output, what's listed under "Enabled hwaccels:"?
[02:11:30 CET] Action: Hfuy happily encodes prores quicktimes directly out of windows software
[02:11:36 CET] Action: Hfuy gives apple the virtual finger
[02:19:35 CET] <Hfuy> What does "qscale" mean?
[02:19:39 CET] <Hfuy> Something to do with the quantiser?
[03:52:05 CET] <pinPoint> does -preset parameter work? I use FAST and SLOW and the slow file was larger. Same crf=20 same output format.
[03:52:16 CET] <pinPoint> s/use/used*
[04:37:14 CET] <pinPoint> also are crf leves different in libx265 vs libx264? is crf 23 on x265 the same quality as crf 23 on x264?
[04:37:32 CET] <c_14> yes, eh no, eh they're different
[04:37:38 CET] <pinPoint> i know both have different compression techniques
[04:38:09 CET] <pinPoint> c_14: is there a site that shows a table of the levels side by side?
[04:38:26 CET] <c_14> none I know of
[04:42:06 CET] <pinPoint> c_14: hevc looks like bad news the more I read about it. the fees are just out of control, aka a loose canon
[04:42:35 CET] <pinPoint> no wonder Open Media Alliance wants their own codec(royalty free)
[04:42:44 CET] <pinPoint> cisco has thor or daala.
[04:43:48 CET] <furq> what's wrong with vp9
[04:43:54 CET] <furq> other than the speed
[04:43:56 CET] <pinPoint> not sure
[04:44:09 CET] <pinPoint> google is likely to pitch its vp9/vp10 ideas to the alliance
[04:44:33 CET] <furq> should they not make vp9 usable before working on vp10
[04:44:50 CET] <pinPoint> right now vp9 takes forever to encode anything... not sure why parallel is offline
[04:45:07 CET] <pinPoint> furq: every year they are pushing updates to it.
[04:47:53 CET] <pinPoint> does anyone know what bitrate netflix/amazon pushes their UHD content to viewers?
[04:50:44 CET] <pinPoint> furq: how do you find googles vp9?
[05:37:54 CET] <TD-Linux> furq, well if you look at libvpx git most of the work is on vp9
[05:39:07 CET] <TD-Linux> a lot of people are happy with vp9 now. but many others want a) input into the design other than 100% google b) it standardized c) better guarantees that it's royalty free
[05:40:00 CET] <TD-Linux> also vpxenc uses multiple cores by default now
[07:23:13 CET] <nilspin> Hi guys
[07:24:28 CET] <nilspin> I have a gif I want to render in opengl, so what I did was using imagemagick generate new images, load them as textures, and render.
[07:24:40 CET] <nilspin> It works fine, but messes up the FPS
[07:25:23 CET] <nilspin> another way I could retain the fps is by converting the gif into an mp4, and decomposing *that* mp4 into images and loading them
[07:26:03 CET] <nilspin> granted this will generate too many duplicate frames, but let's say I am not worried about that for now.
[07:27:18 CET] <nilspin> So, how do I make am mp4 from a gif, with an explicitly defined FPS?
[07:27:23 CET] <nilspin> *an
[07:28:53 CET] <furq> the same way you would make an mp4 from anything else
[07:31:26 CET] Action: nilspin is going through the docs
[07:33:08 CET] <furq> there's no reason to go via mp4 if you just want images at a certain framerate
[07:33:31 CET] <furq> ffmpeg -i src.gif -r 60 dest%04d.png
[09:11:23 CET] <nilspin> furq, thank you. However, I didn't understand the 'dest%40d.png' part (linux noob here :)
[09:13:25 CET] <waressearcher2> nilspin: hallo noob
[09:13:38 CET] <nilspin> waressearcher2, hi.
[09:15:45 CET] <nilspin> ah, its just a format specifier. Stupid me indeed.
[11:06:37 CET] <cheater> hi
[11:07:59 CET] <cheater> i am using aconv, converting from a webm file (~20 minutes long) to mp4 (usually less than 1 minute long). as i play back the mp4 in vlc, the progress bar doesn't progress normally. for example it'll stay on 0, and then only jump to 35 seconds, and then to 48 seconds, and then the video has ended. how do i make this work better?
[11:12:41 CET] <JEEB> I think you have an old version of it, although I will have to mention that avconv comes from Libav, not FFmpeg :)
[11:12:49 CET] <JEEB> #libav would be the correct place for questions regarding it
[11:17:50 CET] <cheater> i thought that was the same thing
[11:18:10 CET] <cheater> well in the end maybe someone knows anyways
[11:18:39 CET] <cheater> my version is from march, so not that old
[11:18:46 CET] <cheater> it's the latest my distro has
[11:25:13 CET] <JEEB> build date doesn't matter
[11:33:55 CET] <cheater> oh right right
[11:33:59 CET] <cheater> ummmmm version 9.18-6:9.18-0ubuntu0.14.04.1,
[11:36:09 CET] <JEEB> not here, on the other channel you're on, which is the right forum for support regarding that thing. or you can grab a static FFmpeg ffmpeg build from one of the linked downloads
[11:54:39 CET] <DrSlony> Hello, how can I check an MP3 file for defects, and is there a tool or way to fix any defects without re-encoding the whole file? I have an MP3 which Clementine reports as being 13 hours long @ 40kbps, while ffplay shows it as 4 hours long @ 128kbps.
[11:54:48 CET] <DrSlony> ffplay's assessment sounds more correct
[11:56:09 CET] <DrSlony> the file in question: http://slayrated.org/stream/raw-2015-12-01.mp3
[12:13:22 CET] <jasom> DrSlony: does the file have a xing header?
[12:14:05 CET] <jasom> DrSlony: and mp3diags should be able to add/fix the vbr header
[12:21:21 CET] <cheater> JEEB: thanks
[12:51:01 CET] <dantti> when calling avformat_write_header I get "mpegts dimensions not set", I have set w/h in codec and would assume avformat_new_stream() would fill it, what am I missing?
[12:52:14 CET] <DrSlony> jasom doesnt look like it has a xing or vbri header
[12:54:41 CET] <DrSlony> thank you for mp3diags
[15:16:57 CET] <shincode> why does CONFIG_FFPLAY comment out in make file when disable-everything but dont disable programs
[15:17:02 CET] <shincode> Arch=arm
[15:17:09 CET] <shincode> where as arch=x86 it does not happen
[15:17:34 CET] <shincode> why does it disable even when i go --enable-ffplay
[15:18:41 CET] <shincode> shared libraries
[15:19:08 CET] <shincode> disable debug and doing release
[15:20:50 CET] <DHE> ffplay requires enabling output devices like SDL so it can play back the video
[16:03:46 CET] <Admin_234234> hey anyone around... i am having trouble getting vdpau installed with ffmpeg.. i installed the rpms ( libvdpau-devel-0.4.1-1.el5.rf.x86_64 & libvdpau-0.4.1-1.el5.rf.x86_64 ) and i also did --enable-vdpau on compile of ffmpeg.. using version N-76957-g7b11eea .. not sure what else to do.. nothing shows up for -hwaccels and i need to decode using the GPU .. any help would be great
[16:06:45 CET] <c_14> After the ./configure, what is listed under "Enabled hwaccels:"?
[16:38:02 CET] <utack> Hi. Is it normal that ffprobe outputs "display_picture_number=0" for every frame? without it there is no way to tell which frame it is actually analyzing, or is "coded_picture_number"  always the same as the "display_picture_number" in H264 streams?
[16:53:27 CET] <DHE> I believe it means the container doesn't offer a frame counter feature or that it can't be reliably measured without explicitly counting them
[17:01:21 CET] <utack> DHE thanks for the information. by "explicitly counting" you mean decoding, which would take forever? because it already goes through all frames with ffprobe and does not "count" them
[17:02:38 CET] <DHE> but you couldn't seek to a random frame and say "this is frame #5123" with certainty
[17:03:43 CET] <Admin_234234> hey c14 sorry had a meeting
[17:03:48 CET] <Admin_234234> nothing shows under enalbed hwaccels
[17:03:50 CET] <Admin_234234> thats the problem
[17:04:31 CET] <utack> DHE certainly not, but i had it start from the beginning and analyze the whole thing
[17:06:52 CET] <c_14> Admin_234234: check config.log
[17:27:32 CET] <Prelude_Zzzzz> hey guys.
[17:27:33 CET] <Prelude_Zzzzz> hey anyone around... i am having trouble getting vdpau installed with ffmpeg.. i installed the rpms ( libvdpau-devel-0.4.1-1.el5.rf.x86_64 & libvdpau-0.4.1-1.el5.rf.x86_64 ) and i also did --enable-vdpau on compile of ffmpeg.. using version N-76957-g7b11eea .. not sure what else to do.. nothing shows up for -hwaccels and i need to decode using the GPU .. any help would be great
[17:27:58 CET] <Prelude_Zzzzz> c14.. config.log is stored where ?
[17:28:05 CET] <Prelude_Zzzzz> in the same compile directory.. checking
[17:44:33 CET] <Admin_234234> hey C14... /usr/include/vdpau/vdpau_x11.h:44:22: fatal error: X11/Xlib.h: No such file or directory
[17:44:42 CET] <Admin_234234> can i get that library installed without actually installed the UI ?
[17:45:45 CET] <cluelessperson> Realistically, are there any properly made live streaming applications?
[17:46:02 CET] <cluelessperson> Most of what I've seen look like command line shoddy mickeymouse implementations.
[17:46:24 CET] <klaxa|work> what have you seen?
[17:46:37 CET] <Admin_234234> i think i just answered my own question :)
[17:49:24 CET] <cluelessperson> klaxa|work, gstreamer /ffmpeg plugins/daemons to act as an http server
[17:55:07 CET] <kepstin> for what, HLS/dash?
[17:55:37 CET] <kepstin> in general, both of those are designed to be served directly as files from a standard http server, no special server logic needed.
[17:56:14 CET] <kepstin> so the hls or dash streaming stuff does basically consist of dropping files into a directory to be picked up by an http server, possibly with some cdn in front of it.
[17:58:44 CET] <prelude2004c_zzz> so another issue... now i got it compiled
[17:58:45 CET] <prelude2004c_zzz> Error while decoding stream #0:7: Invalid data found when processing input
[17:58:45 CET] <prelude2004c_zzz> Cannot open the X11 display .
[17:58:45 CET] <prelude2004c_zzz> VDPAU init failed for stream #0:7.
[17:59:26 CET] <kepstin> some of the gstreamer folks were working on an all-in-one streaming server "gst-streaming-server" which did hls/dash/rtsp, maybe other formats, but i don't think it really went anywhere. Not sure of the current state.
[18:15:30 CET] <prelude2004c_zzz> can anyone help ? i am running a linux shell .. i compiled it ok with having the x11_devel installed but it still will not connect to use the card
[18:15:38 CET] <prelude2004c_zzz> does this mean i have to actually install the UI for the system ?
[18:15:48 CET] <prelude2004c_zzz> i dind't want to do that as i don't need it at all and use everything in ssh
[18:15:52 CET] <prelude2004c_zzz> can anyone assist ?
[18:19:45 CET] <kepstin> as far as I know, vdpau is only available when running inside X, which is kind of a pity. what is your intended use? nvidia gpu encoding?
[18:21:06 CET] <kepstin> if so, you'd probably want to look at using the nvenc rather than vdpau
[18:24:42 CET] <prelude2004c_zzz> gpu decoding
[18:24:50 CET] <prelude2004c_zzz> i already use nvenc and it is working well
[18:24:56 CET] <prelude2004c_zzz> the problem i am having is on the decoding side
[18:25:08 CET] <prelude2004c_zzz> i dont' have enough cpu power to decode h264 correctly
[18:25:14 CET] <prelude2004c_zzz> so i need to offload the decoding to the GPU too
[18:25:23 CET] <prelude2004c_zzz> the M4000 has both a decoder and encoder built in
[18:37:30 CET] <prelude2004c_zzz> help.. i need somebody .. help.. not just anybody.. help.. i need someone .. HELLLLPP !!
[18:37:31 CET] <prelude2004c_zzz> :)
[18:58:27 CET] <dantti> I now have my code to encode with h264 then mux to mpegts, the problem is that I'm probably doing something wrong with avframe->pts, when I was creating a raw h264 I set QFrame->startTime() and everything went well, but mpegts it seems to want an increasing number which creates a "1sec" video
[18:58:41 CET] <dantti> how should I deal with pts?
[18:59:18 CET] <dantti> I was setting pts to 1 on first frame, 2 and so on...
[18:59:30 CET] <prelude2004c> anyone know centos ? vdpauinfo: cannot connect to X server :0.0 .. i am on the home strech and can't get it going
[18:59:36 CET] <dantti> it doesn't show any warnings but the output is odd
[18:59:41 CET] <prelude2004c> centos channel is dead
[19:05:31 CET] <DHE> prelude2004c: you're logged into the right server as the right user for an existing X11 session?
[19:08:23 CET] <prelude2004c> i am root
[19:09:14 CET] <prelude2004c> i installex x11-devel and thats aobut it
[19:12:44 CET] <Mavrik> dantti, MPEG-TS should probably have 1/90000 timebase :)
[19:12:58 CET] <Mavrik> meaning that frame at 0sec = 0pts, 1sec = 90000pts, etc.
[19:13:06 CET] <Mavrik> and time_base on stream should be set to 1/90000
[19:13:19 CET] <dantti> Mavrik: 90000 instead of stream->time_base = (AVRational){ 1, 25 }; ?
[19:13:30 CET] <dantti> *instead of 25
[19:14:38 CET] <dantti> and should I calculate the seconds my self? by probably using QFrame->startTime()?
[19:16:31 CET] <Mavrik> I have no idea what startTime() does ;)
[19:16:35 CET] <dantti> on the mux example there is ost->frame->pts = ost->next_pts++; which I did the same, so I'm unsure how to relate that :P
[19:16:41 CET] <Mavrik> You should set PTS so the timestamps on the frames will be good.
[19:16:53 CET] <Mavrik> PTS sets time at which the frame has to be displayed
[19:17:00 CET] <Mavrik> It's expressed in timebase units
[19:17:07 CET] <dantti> Returns the presentation time (in microseconds) when a frame should stop being displayed.
[19:17:17 CET] <Mavrik> Start or stop? :)
[19:17:18 CET] <dantti> *should start
[19:17:29 CET] <Mavrik> Well, then you should use that and convert it to your timebase
[19:17:30 CET] <dantti> copied the docs from the endTime :P
[19:18:04 CET] <Mavrik> (startTime / 1000 0000) * (90000 / 1) :)
[19:18:21 CET] <Mavrik> (Watch rounding and stuff)
[19:19:06 CET] <dantti> and (AVRational){ 1,  90000 }; right?
[19:19:50 CET] <Mavrik> Yep, that's the standard for the container, should be set on AVFormatContext too I think (keep mixing those up -_-)
[19:23:59 CET] <dantti> ok, that didn't work, maybe rounding is to blame :P
[19:27:56 CET] <Mavrik> dantti, for 25fps stream, the PTS has to be 0, 3600, 7200, etc.
[19:29:29 CET] <dantti> shouldn't it be 0, 25, 50?
[19:34:06 CET] <Mavrik> On what basis? :)
[19:34:28 CET] <dantti> 1, 15?
[19:34:32 CET] <dantti> 1, 25
[19:36:11 CET] <dantti> I'm not sure how many frames will I get, so if I get 15 frames in a second pts is 1...15 then 26...50 ?
[19:36:48 CET] <Mavrik> dantti, but didn't you say you get frame timestamps from the source_
[19:36:50 CET] <Mavrik> ?
[19:36:55 CET] <dantti> yup
[19:37:39 CET] <dantti> should I store that value from the first frame and then remove it as a base?
[19:38:57 CET] <prelude2004c> hey can anyone help me.. i am sooo close but i can't figure out this last thing... using vdpau.. i have it all there but its saying tha tit can't connect to X server ; tried xhost + ; tried sshd_config x11forward  = yes .. i am out of ideas
[19:39:08 CET] <Mavrik> dantti, you don't have to, you have to convert to right time units.
[19:39:24 CET] <Mavrik> prelude2004c, you need an active X server with a GPU driver enabled.
[19:39:50 CET] <prelude2004c> how does one do that though .. i have never done this before
[19:40:00 CET] <dantti> this seems to be rounding to 0 always (qFrame->startTime() / 10000000) * (90000 / 1)
[19:40:18 CET] <prelude2004c> yum install xorg-x11-server-Xvfb < ran this
[19:40:24 CET] <prelude2004c> running on port 6001 it seems
[19:40:31 CET] <prelude2004c> i have an nvidia M4000 card installed
[19:45:51 CET] <dantti> ok, startTime() is always -1, I guess that's due the source being the camera, Qt probably sets that on video playback
[19:46:22 CET] <dantti> I wonder why the raw h264 had it fine...
[19:54:41 CET] <dantti> Mavrik: I guess I need a reference clock then no, and check with a reference to know when a second has passed? for a variable fps should I just drop more than 25 frames or is there some better approach, since this will go through network I guess 25fps is a good number...
[19:54:58 CET] <Mavrik> Do you have variable FPS or static FPS?
[19:55:19 CET] <dantti> I think it's variable as I have no control over it
[19:55:35 CET] <dantti> in fact I think those are the frames displayed by the GPU
[19:57:40 CET] <Mavrik> Well do check
[19:58:48 CET] <dantti> not sure how
[20:08:57 CET] <dantti> ok, as it seems it's indeed variable
[20:09:58 CET] <dantti> but I can set a maximum frame rate it will have
[20:11:15 CET] <prelude2004c> can someoen help me please. Cannot open the X11 display .
[20:11:15 CET] <prelude2004c> VDPAU init failed for stream #0:5.
[20:11:23 CET] <dantti> Mavrik: for a variable fps I guess I need to calculate the frame time myself right? otherwise would just be jumping
[20:11:34 CET] <prelude2004c> when i try to use it as -hwaccel .. using root on a centos 7 install .. no GUI
[20:12:17 CET] <dantti> I mean a static FPS is just multiples of itself I think
[21:42:02 CET] <shincode> that --enable-outdev=sdl made it work
[21:42:11 CET] <shincode> thanks whoever said that like 6 hours ago
[21:44:02 CET] <yongyung> So since the
[21:44:03 CET] <yongyung> Past duration 0.999992 too large
[21:44:03 CET] <yongyung>     Last message repeated 20 times
[21:44:12 CET] <yongyung> message doesn't seem to actually do anything
[21:44:15 CET] <yongyung> Can I disable it?
[21:54:40 CET] <shincode> anyone good with xrdp and can make it reuse session?
[21:55:07 CET] <shincode> everytime i switch port=-1 to port=3399 or any port not used it goes from working to not working
[21:55:14 CET] <shincode> all of firewall is destroyed and off
[23:28:29 CET] <Oetker> Hello. I am trying to download a DRM free silverlight stream. It has a ism/manifest, but the url has a token. Whenever i put the entire url into ffmpeg with the token i get "invalid data found when processing input"
