[03:12:27 CEST] <FlorianBd> Hi there! When extracting pictures using -r 0.1 for example, is there a way to apply an rgb level range to it? e.g. I want the output to be from 8 to 180 instead of 0 to 255.
[03:12:49 CEST] <FlorianBd> so it's like RGB curves but total linear
[03:12:52 CEST] <FlorianBd> totally
[03:16:23 CEST] <FlorianBd> hmm I think I found :)    -filter_complex 'colorlevels=aomin=0.0353:aomax=0.706'    correct?
[03:24:04 CEST] <Yay295> Hello. Just wondering, if I did "crop=iw:ih:0:0", does ffmpeg know to ignore that option?
[03:33:56 CEST] <FlorianBd> ok so no, that does not work:       -filter_complex 'colorlevels=aomin=0.0353:aomax=0.706'
[03:48:19 CEST] <FlorianBd> AHHH ok, a is alpha of course... so if I want all channels I need to specify all r, g and b
[04:12:06 CEST] <kepstin> Yay295: it'll still have some overhead because it still has to go through the crop filter. The crop filter is ridiculously fast anyways, so I wouldn't worry
[04:12:41 CEST] <kepstin> (crop filter doesn't actually copy or modify any video data, it just changes buffer metadata like offset, stride, line count, row count)
[04:18:06 CEST] <Yay295> Okay, thanks.
[09:39:00 CEST] <Thor________> hi, anyone know if ffmpeg can act as a RTPM server ?
[09:59:29 CEST] <pfelt> evening all.  i'm trying to generate a 2x2 grid (using [hv]stack) of udp based streams.  i'm having a heck of a time trying to find a way to enable me to change what is being displayed on one of the grid items without having to restart the entire process.  i'd like to be able to kill one of the udp feeds on the source side and not have ffmpeg croak
[09:59:40 CEST] <pfelt> anyone have any ideas on how to do this?
[10:02:58 CEST] Action: pfelt is having a hard time understanding why this is so difficult
[15:03:39 CEST] <KevinA> Hello, I'm trying to build the latest FFMPEG on windows using VS2015.  I've had success with VS2013 before.  My config is ./configure --toolchain-msvc --enable-shared --arch=i386
[15:04:54 CEST] <KevinA> It configures fine. When I type make I get a message """Make: *** No rule to make target `libavdevice/avdevice.dll', needed by `all-yes`. Stop"""
[15:05:30 CEST] <KevinA> If i enable-static.  I fails to link swscale
[16:45:36 CEST] <vanila> hello
[16:45:53 CEST] <vanila> what is the fastest way to take screenshots of various times in a video?
[16:56:21 CEST] <TheGreatDoc> Hi all
[16:58:12 CEST] <TheGreatDoc> I finally have working ffmpeg to udp multicast. Now I have a little problem with the decklink card
[16:58:39 CEST] <TheGreatDoc> If the input fails and come up again, I have to reset the ffmpeg
[16:59:22 CEST] <TheGreatDoc> Also, would be awesome if the input fails, ffmpeg shows an image and when input comes back start streaming the input again
[17:20:14 CEST] <Yo[x]> Hello, Trying to install kdenlive but can't add any video clip due to library codec problem. ffmpeg and libav are involved in this problem. I got this result with avplay video playing test : http://pastebin.com/u2gzd29W.  I don't know where i have to  go to find a way to solve this issue. thanks for any help.
[17:41:00 CEST] <DHE> I'm trying to follow the source code examples for decoding video. I have successfully opened an MPEG2 decoder and got back a 1920x1080 AVFrame, but the AVCodecContext that goes with it still has codec->width and codec->height unset. How do those get set? I'm using examples/transcoding.c open_input_file() as a starting point
[17:55:54 CEST] <Yo[x]> ok sorry.  forget my question.  It's work with mplayer using ffmpeg/libav decoder. So issue is not from ffmpeg/libav
[17:57:23 CEST] <DHE> regarding my issue, as far as I can tell avformat_find_stream_info is supposed to provide this but it's not...
[17:59:57 CEST] <newbie_ffmpeg> Hi all, I am trying to add a cross fade to a video of 1 second each. http://pastebin.com/AG3UJguT The input and the output are present here.
[18:00:33 CEST] <newbie_ffmpeg> The problem is that the output framerate etc is different from the input
[18:00:55 CEST] <newbie_ffmpeg> Is there a way for me to get the same characteristics as the input videos when adding the cross fade?
[18:16:20 CEST] <kepstin> newbie_ffmpeg: I don't know if it would help, but you don't need to use a lavfi input with the color filter; you can include it in a filter_complex string directly.
[18:16:56 CEST] <kepstin> (and the color filter takes a framerate of the video it generates as an option - this should be set to match the input streams)
[18:17:11 CEST] <newbie_ffmpeg> <kepstin> Can you please show me an example?
[18:17:15 CEST] <kepstin> you might want to normalize all the videos to the exact same framerate e.g. with the fps filter.
[18:18:14 CEST] <kepstin> -filter_complex 'color=black:s=1280x720:r=30[black]; ... rest of filter chain ...'
[18:18:28 CEST] <kepstin> where you can then use [black] as an input to another filter
[18:18:57 CEST] <newbie_ffmpeg> <kepstin> Thanks I will try that!
[18:44:47 CEST] <DHE> yeah, I try to use the example transcoding.c sample and the codec parameters (width, height) etc are filled in. I try with my code which is functionally similar but I get nothing in those fields, but I do get coded_width/height set.
[18:54:33 CEST] <DHE> oh I'm an idiot... I found out what's wrong.. miscompilation
[19:00:06 CEST] <pikaro> hi! I'd like to use ffmpeg to record from ALSA with as little a gap as possible. for that, a python script terminates the previous ffmpeg process and immediately starts a new one. this is apparently too rapid as I get "device busy" errors. at what point does the device get freed by ffmpeg? is waiting for the process to terminate reliable enough? or is this more of an alsa question, i. e. does the device maybe stay busy after ffmpe
[19:00:06 CEST] <pikaro> g exits?
[20:03:23 CEST] <zamba> which connection gives the best quality: composite or s-video?
[20:04:41 CEST] <zamba> oh.. looks like it's s-video
[20:10:30 CEST] <DHE> RF < composite < s-video < component < HDMI
[20:17:31 CEST] <zamba> i so didn't know that
[20:18:15 CEST] <zamba> how much difference is there in practice between s-video and composite?
[20:21:29 CEST] <blop> hello ;)
[20:22:28 CEST] <blop> is it possible to disable audio decoding while using -acodec copy ? ffmpeg keeps trying to decode AAC and fail, but all I need is copy
[20:23:26 CEST] <c_14> Not that I know of, and don't post user questions in #ffmpeg-devel
[20:24:00 CEST] <c_14> You might want something like mp4box or mkvtoolnix or l-smash
[20:24:04 CEST] <c_14> Something that only remuxes
[20:24:31 CEST] <blop> ok thanks :) i will give a try at those
[20:26:01 CEST] <furq> zamba: that's not really easy to quantify
[20:26:13 CEST] <furq> it's significant enough that you should be able to tell the difference
[20:26:36 CEST] <furq> although things like cable quality will make a difference
[20:28:42 CEST] <zamba> when using ffmpeg to capture from the device, how can i select s-video as input?
[20:29:03 CEST] <furq> there are some comparison videos on youtube but they all seem to be of games consoles
[20:29:25 CEST] <furq> and i imagine that depends on your capture device
[20:30:02 CEST] <JEEB> blop: here I mean :P
[20:30:05 CEST] <blop> yes
[20:32:37 CEST] <blop> JEEB : I'm trying to copy an encrypted mpeg-ts stream (for recording purpose). If I use -an it's working as expected, but I need to preserve audio of course. And ffmpeg is detecting aac audio channels and try to decode them. Then I have tons of "AAC bitstream not in ADTS format and extradata missing" and finally a "AAC packet too short" followed by "av_interleaved_write_frame(): Invalid data found when processing input"
[20:33:32 CEST] <JEEB> blop: pastebin full command line and terminal output. although I guess it fails even before it starts doing anything
[20:33:33 CEST] <blop> all streams are mapped as "(copy)" but somehow it tries to decode the AAC inputs (which fails because it's encrypted)
[20:33:47 CEST] <JEEB> I want to check how it exactly fails
[20:34:58 CEST] <blop> for example http://pastebin.com/dWc9THSS
[20:35:47 CEST] <JEEB> and same happens with straight-up mpeg-ts output as well?
[20:35:59 CEST] <llogan> zamba: how are you going from device to ffmpeg? what type of device is it?
[20:36:26 CEST] <blop> JEEB: yes it fails with a plain.ts file too
[20:36:47 CEST] <JEEB> as in output, right?
[20:36:53 CEST] <blop> yes
[20:37:47 CEST] <blop> with only: ffmpeg -i udp://239.192.5.46:7092 -c copy -sn out.ts
[20:37:51 CEST] <JEEB> might be trying to parse rather than decode...
[20:38:02 CEST] <blop> yes maybe
[20:38:13 CEST] <JEEB> because remuxing is after all demux and remux
[20:39:17 CEST] <blop> i don't get why it needs to parse the audio channels :)
[20:39:44 CEST] <zamba> llogan: i believe it's an easy cap dc-90
[20:39:46 CEST] <blop> using -an fix the issue, no more warning/errors
[20:40:45 CEST] <zamba> llogan: i use -f video4linux2 with ffmpeg, but it seems to be fixed on composite input
[20:40:50 CEST] <JEEB> blop: because it's needed to correctly mux the stream again I would think :) if you can demux and then remux without doing that, then sure
[20:41:15 CEST] <JEEB> in that case ffmpeg.c or libavformat is doing non-required stuff
[20:41:25 CEST] <JEEB> in which case a bug report + a short sample would be in place
[20:41:42 CEST] <JEEB> (it's encrypted so I'd guess it'd be relatively easily provide'able)
[20:42:19 CEST] <zamba> llogan: for mencoder/mplayer it's said to use :input=X to specify which input to use, but i'm not able to do that with ffmpeg, as far as i can tell?
[20:42:25 CEST] <blop> JEEB:  i guess it's trying to parse too much yes. The stream is encrypted using a mainstream DRM system and is remuxable by some professional appliance
[20:42:44 CEST] <Raiz> ffmpeg is complaining about missing codecs, where I can find those?
[20:42:48 CEST] <blop> i will open a bug report tomorrow ;)
[20:42:53 CEST] <JEEB> yeah, if remuxing is done on a more high level
[20:43:03 CEST] <llogan> zamba: does the device not have a switch on it to select which one to use?
[20:43:17 CEST] <JEEB> basically take the stream and don't even try to touch it. of course that doesn't let you remux to other containers
[20:43:33 CEST] <JEEB> which is what the ffmpeg.c's remuxing does
[20:43:47 CEST] <zamba> llogan: nope
[20:43:47 CEST] <JEEB> it effectively strips things out of the container, then puts them into another
[20:43:54 CEST] <furq> Raiz: which codecs
[20:44:11 CEST] <zamba> llogan: i believe this is done in the kernel module
[20:44:15 CEST] <Raiz> I want to convert an mp4 to ogg file
[20:44:16 CEST] <zamba> llogan: or by the application
[20:44:17 CEST] <JEEB> the fact that input and output containers match in this case don't cause any simpler code path to be used :)
[20:44:35 CEST] <Raiz> it's codec theora
[20:44:36 CEST] <JEEB> I'm actually thinking of making something that remuxes limited streams, too
[20:44:51 CEST] <JEEB> because I have a need for limiting streams that go through
[20:44:56 CEST] <JEEB> so PMT and things have to be rewritten
[20:45:08 CEST] <JEEB> but the actual PIDs' contents can be kept as-is
[20:45:15 CEST] <blop> :)
[20:45:25 CEST] <furq> Raiz: -c:v libtheora
[20:45:36 CEST] <furq> assuming you actually want to keep the video
[20:46:04 CEST] <furq> if that's missing then you need to recompile ffmpeg or install a binary with libtheora included
[20:46:06 CEST] <Raiz> unknowing encoder: libtheora :(
[20:46:17 CEST] <blop> i will provide a sample input.ts with the bug report. I know it's a strange use case, but ffmpeg should also be usable strictly as a remuxer :)
[20:46:26 CEST] <Raiz> sigh
[20:46:34 CEST] <furq> do you actually want to convert the video or just the audio
[20:47:11 CEST] <Raiz> I download music from utube and I want to get rid of the video part of them and leave them as audio files
[20:47:17 CEST] <furq> use -vn then
[20:47:34 CEST] <zamba> llogan: yup, i can do it with mencoder and :input=1 passed
[20:47:34 CEST] <Raiz> for what format I'd convert that?
[20:47:41 CEST] <furq> i wouldn't convert it at all
[20:47:49 CEST] <Raiz> mp4 without video?
[20:47:52 CEST] <furq> -i src.mp4 -vn -c:a copy dest.m4a
[20:48:06 CEST] <Raiz> that's m4a
[20:48:19 CEST] <furq> well yeah that's what i would do
[20:48:29 CEST] <furq> if you specifically want ogg then -i src.mp4 -vn dest.ogg
[20:48:35 CEST] <furq> that'll reencode to vorbis
[20:48:46 CEST] <furq> if you don't need to do that then you shouldn't because you'll lose quality
[20:49:00 CEST] <Raiz> converted it to wav :D
[20:49:39 CEST] <furq> well i guess at least that doesn't lose quality
[20:49:54 CEST] <Raiz> video quality or audio quality?
[20:50:17 CEST] <furq> which do you think
[20:50:21 CEST] <Raiz> audio
[20:50:24 CEST] <furq> hooray
[20:50:25 CEST] <blop> JEEB: thank you for your help ;)
[20:50:42 CEST] <furq> i have no idea what situation you're in where you can use wav or ogg but not aac
[20:50:47 CEST] <furq> but ok
[20:51:04 CEST] <Raiz> trying ogg
[20:51:12 CEST] <Raiz> but what did the -vn option do?
[20:51:18 CEST] <furq> no video
[20:51:55 CEST] <Raiz> it's better now, it's a chiptune so quality is not a big deal
[20:52:18 CEST] <furq> dare i ask what chiptune
[20:52:43 CEST] <llogan> zamba: you can see what is available with ffmpeg -f v4l2 -list_formats all -i /dev/video0
[20:52:55 CEST] <llogan> or "v4l2-ctl --list-formats-ext"
[20:52:58 CEST] <Raiz> 4-mat - rose
[20:53:31 CEST] <furq> you know ffmpeg has libmodplug support, right
[20:53:38 CEST] <Raiz> nope
[20:54:57 CEST] <furq> http://api.modarchive.org/downloads.php?moduleid=157314#4-mat_-_rose.xm
[20:55:02 CEST] <furq> well now you can convert it in a less ridiculous way
[20:55:11 CEST] <furq> or just listen to the xm
[20:55:33 CEST] <Raiz> I use ffplay to run video/audio, can it read xm files?
[20:56:20 CEST] <furq> if it was compiled with libmodplug support then sure
[20:57:20 CEST] <furq> you should probably use a non-debug video player like mpv though
[20:58:01 CEST] <Raiz> since ffplay comes with ffmpeg and all the codecs, why would I install more software :P
[20:58:11 CEST] <furq> because ffplay is a really bad video player
[20:58:29 CEST] <Raiz> I was using mplayer in the past
[20:58:36 CEST] <thebombzen> furq: ffplay is great for certain uses
[20:58:51 CEST] <JEEB> ffplay is a proof of concept / example kind of thing. if it works for you, great. but don't expect it to have good rendering or anything like that
[20:59:12 CEST] <furq> yeah it's good for debugging but not much else
[20:59:18 CEST] <JEEB> mpv is probably the least retarded child of the mplayer family, both on *nix as well as on windows or OS X
[20:59:21 CEST] <Raiz> what you use then?
[20:59:24 CEST] <furq> mpv uses the ffmpeg libs
[20:59:34 CEST] <furq> and is generally more usable and looks much nicer
[20:59:51 CEST] <thebombzen> if you're looking for a video player that works best, I'd use mplayer but make sure you compile it against ffmpeg and not libav
[20:59:56 CEST] Action: JEEB actually had fun getting mpv running on android, too
[21:00:16 CEST] <furq> obviously if you're on windows then mpc-hc is the ultimate king
[21:00:19 CEST] <JEEB> thebombzen: recommending mplayer instead of any more maintained fork? color me surprised!
[21:00:22 CEST] <JEEB> furq: not really
[21:00:33 CEST] <JEEB> mpv has windows as a first class citizen
[21:00:44 CEST] <JEEB> opengl renderer works with d3d through ANGLE
[21:00:49 CEST] <JEEB> and there's a wasapi audio renderer
[21:00:49 CEST] <furq> i know, i have it installed
[21:00:52 CEST] <furq> i still prefer mpc-hc
[21:01:09 CEST] <JEEB> I've worked with mpc-hc and DirectShow for years
[21:01:11 CEST] <furq> it sucks for streaming, though
[21:01:13 CEST] <JEEB> and I just can't take it any more
[21:01:20 CEST] <thebombzen> JEEB: sorry if I'm missing sarcasm here, but mplayer is maintained
[21:01:20 CEST] <furq> what's wrong with it
[21:01:28 CEST] <thebombzen> there was a minor release two months ago
[21:01:31 CEST] <JEEB> thebombzen: *more* maintained
[21:01:34 CEST] <furq> other than where you just said "directshow" obviously
[21:01:43 CEST] <JEEB> mplayer does have one or two guys kind of poking at it
[21:01:58 CEST] <JEEB> furq: the UI is OK but I'm just getting tired of all the issues related to DShow
[21:01:58 CEST] <thebombzen> in that case, what is *more* maintained than mplayer? i.e. which player should I be using instead
[21:02:03 CEST] <Raiz> okay, will try mpv
[21:02:09 CEST] <furq> thebombzen: mpv
[21:02:14 CEST] <JEEB> you should be using whatever you have decided to be best for you
[21:02:24 CEST] <JEEB> mpv is the most maintained mplayer fork currently
[21:02:26 CEST] <thebombzen> right, which was mplayer, and I decided that based on limited knowledge
[21:02:40 CEST] <thebombzen> if mpv is essentially mplayer then I'll probably use that
[21:02:53 CEST] <thebombzen> first I'll have to rebuild git master of ffmpeg though, I'm a bit overdue on that ;-)
[21:02:56 CEST] <JEEB> mpv was forked off a fork of mplayer with various improvements and clean-ups
[21:03:03 CEST] <furq> i like the fact that nobody has yet recommended vlc
[21:03:07 CEST] <furq> long may it continue
[21:03:14 CEST] <JEEB> I use VLC for non-playback usage
[21:03:27 CEST] <thebombzen> haha vlc can't use libass on linux. really annoying
[21:03:36 CEST] <JEEB> huh, it can just fine
[21:03:40 CEST] <furq> i occasionally use it for streaming, but mpv seems to be just as good for that
[21:04:21 CEST] <thebombzen> JEEB: really? I built vlc 3.0.0 from git recently and it says "unrecognized codec ID" and references the streams with the TTF/OTF font files
[21:04:29 CEST] <thebombzen> whereas mplayer can just, render it fine
[21:04:36 CEST] <JEEB> that's not up to libass really
[21:04:51 CEST] <JEEB> and I don't think the fonts are streams, they're supposed to be attachments
[21:05:04 CEST] <thebombzen> you're right, they are. mispoke
[21:05:05 CEST] <JEEB> if you have muxed in OTF or TTF as a stream, then congratulations :P
[21:05:11 CEST] <thebombzen> I mean, vlc can't just render ASS subs the way mplayer can.
[21:05:17 CEST] <thebombzen> it just errors and makes me sad
[21:05:21 CEST] <thebombzen> unless I"m doing it wrong
[21:05:24 CEST] <JEEB> it should be able to, at least when I tested :P
[21:05:26 CEST] <thebombzen> it does on Windows though, which is weird
[21:05:35 CEST] <JEEB> because you don't build that yourself most probably
[21:05:49 CEST] <thebombzen> no, the VLC from the repos also can't
[21:05:57 CEST] <thebombzen> I built it myself because I thought it would fix that
[21:06:02 CEST] <JEEB> then something funky's going on around that :P
[21:06:07 CEST] <thebombzen> clearly
[21:06:21 CEST] <JEEB> there can be a VLC bug but that would then affect all OSs
[21:06:42 CEST] <JEEB> anyways, I've only used VLC on android for playback lately (until I got my mpv-android thingy going)
[21:06:49 CEST] <JEEB> and otherwise it's a useful tool for other things
[21:06:54 CEST] <JEEB> I don't even build it with GUI :)
[21:50:19 CEST] <thebombzen> wow that's a big update to ffprobe
[21:52:08 CEST] <JEEB> well dae and nev et al just got The Evil Plan 2 improvements merged into FFmpeg from Libav
[21:52:27 CEST] <JEEB> ffprobe I think got updated for that earlier today
[21:55:20 CEST] <Milardo> Hi i have a question about ffmpeg video filter in the documentation "9.57 framerate"
[21:55:54 CEST] <Milardo> i have heard this filter can be used for motion interpolation
[21:56:22 CEST] <Milardo> Im not sure exactly about the options of it though
[21:56:45 CEST] <kepstin> it doesn't really do motion interpolation, it just blends (crossfades) between two frames.
[21:56:50 CEST] <Milardo> like interp_start and interp_end and scene?
[21:57:57 CEST] <Milardo> so it has nothing to do with it and no matter how i tweak the options, it wont make my video have motion interpolation?
[22:00:26 CEST] <thebombzen> I have a question myself now - sometimes there's animations at 24 fps but for fairly unintensive graphics, parts of it will only be 8 fps - i.e. every three frames are the same.
[22:00:31 CEST] <thebombzen> if I reduce the framerate from 24 fps to 12 fps with "-r", it will appear choppy because every other frame will be duplicated (2 and 3 are relatively prime).
[22:00:40 CEST] <thebombzen> is there a way to make it less choppy? will -vf framerate do the trick, even though I'm reducing the framerate by an integer amount?
[22:00:43 CEST] <durandal_1707> no motion interpolation, yet
[22:01:14 CEST] <Milardo> no filter yet for it in ffmpeg?
[22:05:39 CEST] <kepstin> thebombzen: huh, I don't think I've seen 8fps animations in 24fps video before. No way around that if you use the fps filter (or -r option), but you might be able to play with the 'mpdecimate' filter to get the effect you want.
[22:06:13 CEST] <thebombzen> kepstin: some animes will do that in scenes that are just characters talking. no reason to move the mouth at 24fps
[22:06:31 CEST] <kepstin> anime is animated at 12fps by standard, then frame-doubled to 24
[22:06:39 CEST] <kepstin> 8fps is very rare in it :/
[22:07:39 CEST] <kepstin> I suppose in some really slow bits where they are running out of budget and/or time, you could see 8fps :/
[22:08:33 CEST] <kepstin> There's usually very little reason to bother changing the framerate from 24 (actually 24000/1001), since the video codec will compress the duplicate frames well anyways.
[22:09:02 CEST] <thebombzen> true. inter-prediction is pretty good.
[22:09:34 CEST] <kepstin> but if you really want to remove them, something like the 'mpdecimate' filter will take them out without changing the frame timing, so you get 24fps video with a bunch of skip frames instead of duplicate frames.
[22:10:18 CEST] <kepstin> (or variable framerate output, basically)
[22:12:03 CEST] <Milardo> no filter for motion interpolation in ffmpeg yet?
[22:12:57 CEST] <zamba> llogan: but this doesn't say anything about which input that's going to be used?
[22:14:56 CEST] <zamba> this is the output if i add -loglevel 99: [video4linux2,v4l2 @ 0x4d47340] Current input_channel: 0, input_name: Composite1, input_std: ffffff
[22:15:06 CEST] <zamba> so i basically need to change input_channel to 1
[22:15:14 CEST] <furq> Milardo: there are avisynth/vapoursynth plugins which will do it
[22:15:34 CEST] <Milardo> yes i have seen that
[22:16:09 CEST] <furq> zamba: -channel 1 (maybe)
[22:16:23 CEST] <furq> https://www.ffmpeg.org/ffmpeg-devices.html#Options-17
[22:19:56 CEST] <zamba> that worked.. thanks :)
[23:08:39 CEST] <zamba> hm.. seems like my system is not able to encode two streams in realtime
[23:40:01 CEST] <petecouture> zamba: multi bitrate?
[23:40:15 CEST] <zamba> petecouture: what do you mean by multi?
[23:40:40 CEST] <petecouture> Nm
[23:40:51 CEST] <petecouture> You can encode a single stream to different bitrates
[23:40:55 CEST] <petecouture> for live broadcasting
[23:41:06 CEST] <zamba> oh.. no.. this is different sources
[23:41:07 CEST] <petecouture> Dunno if that's what you ment
[23:41:15 CEST] <petecouture> Gotcha
[23:51:54 CEST] <petecouture> For a live input/output streams, if the bandwidth of the input drops, what's the flag to have the encoder kept encoding the last frame over and over again so it doesn't pause encoding waiting for packets to arrive?
[23:55:58 CEST] <kepstin> ffmpeg doesn't really have anything like that
[23:57:10 CEST] <llogan> the usual once weekly question of how to show static image or another video when another one is unavailable
[23:58:58 CEST] <petecouture> llogan: No I think that's async protocol you're thinking off. I'm trying to make it so that the encoder won't crap out if it hasn't received RTP packets for a while.
[23:59:59 CEST] <petecouture> kepstin: I could have sworn there was something that the encoder will continue processing 'dead air' as filler so the timemark is maintained
