[00:16:01 CEST] <Guster_> hi there
[00:16:19 CEST] <Guster_> can anyone "new" help me plese with ffmpeg
[00:23:27 CEST] <Draz> Padding on video appears grey: Applying pad filter to video stream gives non-black padding. http://pastebin.com/vuHEVSGZ
[00:24:16 CEST] <Draz> I've tried a few things, including applying format filters and outputting with a different codec, but no success.
[00:24:29 CEST] <Draz> Help appreciate.
[00:24:41 CEST] <Draz> *appreciated.
[00:25:10 CEST] <Draz> Guster_, "When asking a question be precise, detailed...". What's your issue?
[00:25:46 CEST] <Guster_> cant unicast with ffmpeg to ffserver
[00:26:20 CEST] <Guster_> there is log from ffmpeg
[00:26:21 CEST] <Guster_> http://pastebin.com/fXw9qw6V
[00:26:44 CEST] <Guster_> at ffserver just Fri Apr 22 00:12:30 2016 127.0.0.1 - - [POST] "/feed1.avi HTTP/1.1" 200 1282
[04:03:52 CEST] <anadon> People kicking around?
[04:28:26 CEST] <DHE> anadon: standard procedure is to ask your question and wait
[04:36:43 CEST] <anadon> DHE: I know, but some channels stay dead for a very long time.  I just ping once in awhile.
[04:38:30 CEST] <DHE> on the other hand it's late in north america, night in europe, and you've wasted valuable time playing IRC tag already.
[04:39:15 CEST] <anadon> DHE: Don't heap on a mistake.
[04:40:13 CEST] <DHE> sorry, just trying to make a point
[05:37:40 CEST] <wyatt8740> Is there a way to make ffmpeg print ONLY info? (meaning I don't want it to print warnings or errors, but only print the information about encoding that you'd get if it were going smoothly)
[05:38:54 CEST] <wyatt8740> I get spammed by distracting 'Past duration [number here] too large' when combining two streams (video and audio devices) into a single capture
[05:39:53 CEST] <anadon> Could you grep through the output
[05:40:07 CEST] <wyatt8740> not while preserving colors, since I'd have to redirect stderr
[05:40:12 CEST] <wyatt8740> info seems to print to stderr too
[05:40:33 CEST] <wyatt8740> and it behaves differently by not using colors if you put it through a pipe
[05:47:34 CEST] <wyatt8740> also, grepping seems to prevent the progress from being displayed
[05:47:40 CEST] <wyatt8740> probably due to buffering or something
[05:48:31 CEST] <anadon> I'd wait for someone more expert than me (I'm not at all)
[05:48:51 CEST] <wyatt8740> fiddling with socat but I never was able to make this work for anything else so my hopes are low
[05:49:20 CEST] <wyatt8740> (once tried to log all communication between my real RS-232 terminal and my PC with socat, it failed miserably)
[05:49:32 CEST] <anadon> That's dedication
[05:50:33 CEST] <wyatt8740> the terminal is really cool and I'm trying to make it work as well as possible :\
[05:50:44 CEST] <wyatt8740> the termcap definitions seem to be missing a few things
[05:51:08 CEST] <wyatt8740> also I was able to discover and report a bug in GNU Nano where syntax highlighting caused the entire screen to redraw with every keystroke
[05:51:31 CEST] <wyatt8740> it happened regardless of terminal but in modern terminal emulators it was so fast no one noticed :|
[05:52:17 CEST] <anadon> wyatt8740: Sounds l=more like you should be bugging #gnu or something.
[05:52:19 CEST] <wyatt8740> http://i.imgur.com/DKBqQ2b.jpg
[05:52:27 CEST] <wyatt8740> no, this is a ffmpeg problem
[05:52:30 CEST] <wyatt8740> I got the nano bug fixed
[05:52:31 CEST] <wyatt8740> :)
[05:52:49 CEST] <wyatt8740> and this ffmpeg problem is not 1985 terminal related
[05:53:05 CEST] <anadon> nethack?
[05:53:16 CEST] <wyatt8740> that's rogue
[05:53:22 CEST] <wyatt8740> I do have nethack here too though
[05:53:33 CEST] <anadon> On a 1985 machine?
[05:53:49 CEST] <wyatt8740> no, lol, that's a terminal
[05:54:09 CEST] <wyatt8740> my i5-3350p desktop PC has rogue and nethack on it :\
[05:54:27 CEST] <wyatt8740> also a serial port
[05:56:05 CEST] <wyatt8740> anyway, if anyone can help me to make ffmpeg not print errors or warnings but still print info messages, please speak up :)
[06:35:35 CEST] <furq> wyatt8740: -v quiet -stats
[06:39:54 CEST] <furq> also i'm disappointed that someone with a 3161 on his desk isn't using irssi
[06:54:20 CEST] <wyatt8740> furq: nice, you recognized the model
[06:54:23 CEST] <wyatt8740> did you use one?
[06:59:08 CEST] <wyatt8740> also when I find a pic I'll show you - I do use irssi on it
[06:59:14 CEST] <wyatt8740> just not in that pic :\
[07:06:11 CEST] <wyatt8740> durandal_1707: I forget, isn't your name taken from Roland's sword? (Roland the knight of charlemagne)
[07:06:36 CEST] <furq> yeah i definitely didn't type "ibm terminal" into google images and then find another picture of your desk
[07:06:48 CEST] <furq> that's not how i know the model number
[07:09:29 CEST] <wyatt8740> furq: oh, okay. But there are about a million and a half IBM terminals
[07:09:41 CEST] <wyatt8740> and I would've been too lazy :\
[07:09:56 CEST] <furq> well your desk is on the second row so it worked out great
[07:10:06 CEST] <wyatt8740> lol
[07:10:09 CEST] <wyatt8740> is it now?
[07:10:31 CEST] <wyatt8740> so it is
[07:10:36 CEST] <wyatt8740> with the amber screen I need to fix
[07:13:48 CEST] <wyatt8740> most of their offerings
[07:13:54 CEST] <wyatt8740> *don't even work on normal PCs
[07:13:58 CEST] <wyatt8740> you need to have a IBM mainframe
[08:17:55 CEST] <wyatt8740> I really think ffmpeg is one of the most awesome free/OSS projects out there. I'd say it along with the linux kernel and maybe QEMU (...and ffmpeg and qemu are both things that were started by Fabrice Bellard. Wow).
[09:17:16 CEST] <thebombzen> does anyone know if the drawtext filter supports WOFF2?
[09:28:35 CEST] <xbloodhound> I have been trying to add two separate animations as png watermarks using something like this -filter_complex "[0:v][1:v][2:v] overlay=0:0" but I am getting error that says too many inputs specified for overlay filter etc. so my question is it possible to add two overlays at all or am I doing something wrong?
[09:29:53 CEST] <xbloodhound> I only know -filter_complex "[0:v][1:v] overlay=0:0" works at least
[09:32:00 CEST] <furq> xbloodhound: [0:v][1:v]overlay=0:0[tmp];[tmp][2:v]overlay=0:0[out]
[09:43:39 CEST] <xbloodhound> ugh that worked thx
[09:43:58 CEST] <xbloodhound> been messing around for a while
[09:59:25 CEST] <termos> is there a way to reduce the blocking time of avio_open? it's taking 500ms each call to open rtmp:// sockets, it's too long when opening 20+ of them
[11:04:54 CEST] <Eiken_> when i apply a cube lut generated in nuke the output looks exactly the same
[11:05:21 CEST] <Eiken_>  -vf lut3d=/mnt/home/erjo/testlut.cube
[11:05:24 CEST] <Eiken_> is this incorrect?
[11:50:54 CEST] <durandal_1707> wyatt8740: nope
[11:58:43 CEST] <aspiers> hi all, any ideas why ffmpeg 3.0.1 would record audio perfectly via pulseaudio, but when I add -f x11grab for screencasting, the audio is truncated at the last ~3s of every capture ?
[11:59:02 CEST] <aspiers> and BTW a/v sync is perfect in this scenario
[11:59:52 CEST] <aspiers> I used: ffmpeg -thread_queue_size 512 -f pulse -i default -ac 1 -f x11grab -video_size 1280x720 -framerate 30 -i :0.0+0+0 -y test.mp4
[13:41:03 CEST] <GusterChe> hi there
[13:41:23 CEST] <GusterChe> me again like last night :D
[13:41:41 CEST] <GusterChe> same problem with my ffmpeg and ffserver :D
[13:42:37 CEST] <GusterChe> anyone with experience to pvt? :D
[13:54:32 CEST] <GusterChe> there are all outputs from ffserver and ffmpeg with ffserver.conf http://pastebin.com/1KxwWQDZ if soneone know what i did wrong please help
[14:01:05 CEST] <GusterChe> is anyone online? xD
[14:13:17 CEST] <GusterChe> hi oldcode
[14:14:36 CEST] <GusterChe> hi fracting :D
[14:15:07 CEST] <BtbN> Don't use ffserver if you can't figure stuff out on your own.
[14:27:08 CEST] <GusterChe> there are all outputs from ffserver and ffmpeg with ffserver.conf http://pastebin.com/1KxwWQDZ if soneone know what i did wrong please help
[15:26:00 CEST] Last message repeated 1 time(s).
[15:29:35 CEST] <Joeboy> Hi. I'm trying to convert some stereo files to mono, but the resulting files seem to get converted from s24le to s16le. Is there a way I can make ffmpeg not do that?
[15:29:38 CEST] <Joeboy> I'm doing:
[15:30:05 CEST] <Joeboy>  ffmpeg -y -i input.wav -map_channel 0.0.0 junk.wav -map_channel 0.0.1 output.wav
[15:36:17 CEST] <furq> -c:a pcm_s24le
[15:36:36 CEST] <Joeboy> Actually -acodec copy seems to work
[15:36:37 CEST] <furq> or maybe -c:a copy will work but i don't think it'll make any difference
[15:36:50 CEST] <furq> yeah that'll do it
[15:36:56 CEST] <Joeboy> Sorry, should have experimented more before asking
[15:38:03 CEST] <furq> if you don't specify then ffmpeg will pick whatever output codec it thinks is best for the output container
[15:38:14 CEST] <furq> which for wav is pcm_s16le
[15:38:39 CEST] <GusterChe> furq: can u help me with my problem?
[15:39:08 CEST] <furq> i can tell you to not use ffserver because it's basically abandoned and it sucks
[15:39:10 CEST] <furq> does that help
[15:39:38 CEST] <GusterChe> yes xD
[15:39:52 CEST] <GusterChe> and, i have one question more if u have some time :D
[15:40:38 CEST] <furq> well that depends on how long it would take to answer the question
[15:40:41 CEST] <GusterChe> if i want to use nginx and rtmp module. do u can give me guildlines? :)
[15:40:55 CEST] <furq> https://gist.github.com/fur-q/d7028f51c38f7d0bb56e
[15:40:56 CEST] <furq> how's that
[15:41:28 CEST] <furq> you can ignore the lua stuff if you don't care about auth
[15:43:37 CEST] <GusterChe> and how to set unicast to server with ffmpeg?
[15:44:09 CEST] <furq> it's rtmp, it only does unicast
[15:56:37 CEST] <GusterChe> furq: thanks, this works fine for now
[15:56:53 CEST] <GusterChe> i go to test it for another things
[15:57:05 CEST] <GusterChe> thanks a lot and cya!
[17:56:39 CEST] <Joeboy> Ok, I asked a question earlier and thought I'd got it sorted but it turns out I hadn't. So I'm going to ask it again.
[17:57:07 CEST] <Joeboy> I'm trying to convert an s24le stereo file into two s24le mono files.
[17:57:58 CEST] <Joeboy> (actually lots of files)
[17:58:17 CEST] <Joeboy> I got as far as: ffmpeg -y -i $f -map_channel 0.0.0 junk.wav -acodec copy -map_channel 0.0.1 "gve-london-audio/oktava/$f"
[17:58:48 CEST] <Joeboy> But that gives me stereo files, for some reason.
[17:59:06 CEST] <Joeboy> without the -acodec copy, I get s16le mono files.
[17:59:51 CEST] <Joeboy> I just want to do a raw copy of one track from the stereo file into a mono file.
[18:01:02 CEST] <Joeboy> ffmpeg (at least my version) doesn't seem to have any 24 bit output options
[18:09:24 CEST] <durandal_1707> Joeboy: -codec:a pcm_s24le
[18:13:08 CEST] <Joeboy> durandal_1707: Thanks!
[20:27:12 CEST] <johnnny22-afk> i have a mpegts that starts at some pts, is there a way to re-encode that pts/dts, so that it starts at 0 ?
[20:28:23 CEST] <c_14> ffmpeg should do that by default
[20:49:25 CEST] <johnnny22-afk> m'ok, but I have a 39h mpegts, which has a rollover around 13h or so from the beginning. ffprobe seems to tell me that the duration is about 13h long. After re-encoding it, ffprobe still tells me that the duration is about 13h. I was hoping to make the duration be ~26h or so, being that max duration of a mpegts without rollovers.. Should I be adjusting something else ?
[20:49:55 CEST] <johnnny22-afk> maybe it's the DTS value that should be changed ?
[20:52:49 CEST] <c_14> ffprobe doesn't actually go through the entire video to find the duration, it usually either uses a value stored in the container
[20:56:17 CEST] <aspiers> hi all, any ideas why ffmpeg 3.0.1 would record audio perfectly via pulseaudio, but when I add -f x11grab for screencasting, the audio is truncated at the last ~3s of every capture ?
[20:56:22 CEST] <aspiers> I used: ffmpeg -thread_queue_size 512 -f pulse -i default -ac 1 -f x11grab -video_size 1280x720 -framerate 30 -i :0.0+0+0 -y test.mp4
[20:57:09 CEST] <c_14> aspiers: is this a regression?
[20:57:39 CEST] <aspiers> c_14: since the last time I tried it, yes - but that was at least 6-12 months ago
[20:58:05 CEST] <aspiers> c_14: A/V sync is still flawless, however
[20:59:37 CEST] <c_14> Can you test with a recent git build? If it still doesn't work with that, open a ticket on trac and mention that it's a regression (preferably mention which release it last worked with)
[21:00:09 CEST] <aspiers> c_14: I already downloaded a static build from git, but it was missing support for pulseaudio :-/
[21:00:16 CEST] <aspiers> and I don't have time to compile one unfortunately
[21:01:16 CEST] <c_14> You can make a bugreport and mention that you only tested with 3.0.1, but the first thing you're going to be asked is if you can still reproduce with a build from git
[21:01:44 CEST] <aspiers> hah
[21:02:26 CEST] <aspiers> yeah, that's fair - although it would only take someone who already has a git build ~20s to copy/paste my command and see if it's the same for them ...
[21:02:40 CEST] Action: c_14 doesn't have pulse
[21:02:42 CEST] <c_14> therefore can't test
[21:02:45 CEST] <aspiers> ok
[21:04:30 CEST] <johnnny22-afk> c_14: aah ok ,right. In my case it's a .ts file, so I'm not sure where it takes that duration value.
[21:04:53 CEST] <johnnny22-afk> c_14: is there a way to make it check the whole file to compute the duration of a particular .ts file ?
[21:06:27 CEST] <johnnny22-afk> maybe -formatprobesize to the whole size of the file ?
[21:07:19 CEST] <c_14> There is -count_packets and -count_frames, but I don't think either is used to get a duration, you can use ffmpeg -i input -f null /dev/null and the last line of output will contain the total duration
[21:08:42 CEST] <johnnny22-afk> yeah, i guess that would be one way :)
[21:09:08 CEST] <johnnny22-afk> adding -c copy for speed : P
[21:11:17 CEST] <CoffeeFluxx> Heyo! I ran a command to mux some h264 video and aac audio into mp4, but somehow it's creating an empty srt track http://pastebin.com/raw/q8T2Ja4K
[21:11:56 CEST] <CoffeeFluxx> Any idea what I'm doing wrong? Neither of the files I'm muxing in has subs, so I'm a bit confused where that came from
[21:12:14 CEST] <c_14> CoffeeFluxx: the m4a presumably had a subtitle trac
[21:12:25 CEST] <c_14> can you pastebin the complete console output of the first command?
[21:12:32 CEST] <c_14> also, it's not srt. It's mov_text
[21:12:32 CEST] <CoffeeFluxx> sure
[21:13:40 CEST] <CoffeeFluxx> http://pastebin.com/raw/ccnWubmm
[21:15:02 CEST] <c_14> hmm, weird
[21:15:14 CEST] <c_14> you should be able to get rid of it with -sn though
[21:16:38 CEST] <CoffeeFluxx> yeah, i checked both the input files and it wasn't there
[21:19:53 CEST] <CoffeeFluxx> it's still there, even after adding -sn
[21:20:08 CEST] <CoffeeFluxx> lemme pastebin
[21:20:24 CEST] <c_14> add -map_metadata -0
[21:22:01 CEST] <CoffeeFluxx> http://pastebin.com/raw/ytfy4Nth
[21:25:16 CEST] <CoffeeFluxx> added the -map_metadata -0, but it's still there
[21:26:41 CEST] <c_14> eeh, honestly no clue. Try updating to a newer build? Does the mov_text stream always show up or only with those two files?
[21:28:19 CEST] <CoffeeFluxx> no clue, normally i'm just muxing to mkv so i use a different program
[21:31:59 CEST] <c_14> Does a subtitle track show up when muxing those 2 files to mkv instead of mp4?
[21:35:45 CEST] <CoffeeFluxx> conversion fails
[21:35:45 CEST] <CoffeeFluxx> http://pastebin.com/raw/fSYti06j
[21:36:16 CEST] <c_14> well, that's fun
[21:36:20 CEST] <c_14> try mpegts?
[21:37:54 CEST] <CoffeeFluxx> same error
[21:40:13 CEST] <c_14> try muxing to mkv with the older build (if you still have that one)
[21:42:21 CEST] <CoffeeFluxx> nope :\
[21:42:23 CEST] <CoffeeFluxx> lemme grab one
[21:44:17 CEST] <CoffeeFluxx> hmm i can't find older windows builds
[21:45:17 CEST] <kepstin> the issue with your most recent command is that the m4a file has a piece of cover art that's being encoded as video
[21:45:31 CEST] <kepstin> you'll want to use some -map parameters to select specific streams
[21:45:42 CEST] <kepstin> e.g. -map 0:a -map 1:v for your most recent example
[21:45:51 CEST] <kepstin> that'll also solve the subtitle issue
[21:46:55 CEST] <CoffeeFluxx> i thik i tried that earlier and it didn't get rid of the subs
[21:47:03 CEST] <CoffeeFluxx> the video is definitely correctly in the output
[21:47:07 CEST] <CoffeeFluxx> i'll try it again, though
[21:50:14 CEST] <CoffeeFluxx> yeah the subs are still there
[21:54:09 CEST] <c_14> It's probably a bug. I'd open an issue on trac, though if there's no good way to reproduce the issue... If you could upload the files (or parts thereof) to reproduce that would probably help
[21:54:24 CEST] <CoffeeFluxx> huh, re-encoded the audio with -map 0:a and it appeared there too
[21:57:18 CEST] <CoffeeFluxx> i'll file a report, though unfortunately i can't upload the files :\
[21:57:48 CEST] <CoffeeFluxx> i'll see if i can repro by encoding some other stuff the same way, though
[22:19:57 CEST] <spirou> if I want to let ffmpeg convert 5.1 sound in a video to normal stereo, would it be very complicated parameters?
[22:20:40 CEST] <JEEB> if input audio channels are mapped in a normal way and in a single track - it should be as simple as -ac 2 after input
[22:21:11 CEST] <JEEB> it only gets complicated if you have to start doing channel mapping or multiple tracks into channels of a single track
[22:21:13 CEST] <spirou> since I have to let it reencode the sound anyway to make the TV accept it, I guess I could tell it to so stereo
[22:22:57 CEST] <spirou> (I have a mp4, that the tv didn't like, and when I had ffmpeg put it in a mkv instead (with -c copy) there was no sound, so I assume the tv don't like that kind of sound, or that kind of sound in a mkv)
[22:23:02 CEST] <spirou> "Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 447 kb/s (default)"
[22:24:38 CEST] <spirou> JEEB: ok so like this then?   ffmpeg -i in.mp4 -ac 2 -vcodec copy out.mkv
[22:24:54 CEST] <JEEB> add -c:a aac -b:a 192k or so
[22:25:20 CEST] <JEEB> if it complains about experimentality then update FFmpeg or add -strict experimental which enables "experimental" features
[22:26:08 CEST] <JEEB> and you might want to use -c:v copy for video in the short way as well in later commands :)
[22:27:15 CEST] <spirou> aha, the "-c:v copy" would be the new way of say "-vcodec copy"
[22:27:22 CEST] <JEEB> yup
[22:30:09 CEST] <spirou> yeah I had to write  -strict experimental  after the input file. I assume it is same thing as  -strict -2  as it suggested
[22:30:31 CEST] <spirou> btw, what do "[matroska @ 0xa79c120] Codec for stream 0 does not use global headers but container format requires global headers" means?
[22:31:41 CEST] <JEEB> spirou: yeah - except the text-based value is generally more understandable than "-2" which is the internal value :)
[22:31:57 CEST] <JEEB> also you should generally update your FFmpeg
[22:32:08 CEST] <JEEB> the aac encoder was vastly improved recently
[22:32:14 CEST] <JEEB> and the experimental flag was removed
[22:32:36 CEST] <JEEB> among other improvements
[22:35:12 CEST] <spirou> ah yeah I'm still on "7:2.8.3+git1~trusty1", I haven't updated for some time...  the newest would be "7:3.0.0+git1~trusty1" it says here
[22:37:01 CEST] <spirou> I'll should remember to let it do its updates before doing anything I want to store permanently
[22:39:33 CEST] <epifanio> Hi
[22:39:50 CEST] <spirou> Ideally I should try to make some ffprobe-using script that could tell if the TV would be OK with a file...
[22:39:55 CEST] <spirou> hello epifanio
[22:41:33 CEST] <epifanio> Im dealing with 2 windows applications (for which I do not have access to the src code), the first one takes as input a directory with png and generates a .avi as output. The second application takes the .avi (previously generated) as input, and try to make a mosaic from each frame
[22:41:56 CEST] <epifanio> i want replace the first application with some open source code, using ffmpeg
[22:42:32 CEST] <CoffeeFluxx> submitted a bug report - any suggestions in the meantime on how to work around the issue?
[22:42:53 CEST] <epifanio> i do know how to generate a video using a sequence of pngs with ffmpg, but my output is not compatible wiht the input video needed by the second application
[22:43:42 CEST] <epifanio> so, I tried to  run ffmpeg -i goodoutput.avi on the file generated by the  first application, this is the output https://gist.github.com/e7ef38889217aee0fa1e1aefceeaf2a8
[22:44:39 CEST] <epifanio> can you suggest me the correct syntax/codec i need to use with ffmpeg to generate a video of the same type as the one described by the ffmpeg -i output?
[22:44:45 CEST] <kepstin> epifanio: should be as simple as setting the codec to match, "-c:v rawvideo -pix_fmt bgr24"
[23:13:34 CEST] <epifanio> kepstin: Thank you! Im trying with:  !cat *.png | ffmpeg -framerate 5 -f image2pipe -c:v png -i - -c:v rawvideo -pix_fmt bgr24 test3.avi
[23:14:26 CEST] <epifanio> ive a video  output, but the framerate is not accepted this the log:   https://gist.github.com/31592fd73aa4569a73dd73a30422e31a
[23:15:34 CEST] <epifanio> debug
[23:16:19 CEST] <epifanio> the app which triys to open the video goes in segfault
[23:17:58 CEST] <epifanio> this the log of ffmpg -i on the output video i used:   https://gist.github.com/74270e975ae79348c44c63db6467cd3c
[23:17:58 CEST] <epifanio>  
[23:18:15 CEST] <epifanio> the fps are set correctly
[23:20:51 CEST] <epifanio> ill try again ffmpeg -i on both files and post here to double check their format match
[23:24:03 CEST] <epifanio> the output is https://gist.github.com/epifanio/f9ec086b2f946a56583cf46f1de47fcf   left.avi  is the video which works as input for the app Im using, test3.avi  is the one i generated with ffmpeg
[23:26:24 CEST] <kepstin> epifanio: I don't see any notable differences.
[23:26:46 CEST] <kepstin> if the application that tries to open it segfaults, well, that's a pretty bad application bug...
[23:27:01 CEST] <kepstin> that said, you might want to try making the height/width a multiple of 8 or 16.
[23:27:12 CEST] <epifanio> it is  a vey bad app which they are forcing me to use .. :(
[23:27:26 CEST] <kepstin> at this point, you're just debugging that application :/
[23:29:44 CEST] <epifanio> they just dont care, they give me an app which work (please let me use this term & I know) that takes a directory with some png and make a video out of it & my problem is that i have 70.000 images and i need to group them in subfolders of 20 images each .. then make videos for each subfolder
[23:30:31 CEST] <epifanio> so i wanted to script my way to generate those videos, on my unix machine .. rhater than klick who knows how many times on a windows application gui
[23:31:22 CEST] <epifanio> i saw a little difference in the metadata:   encoder         : Lavf57.25.100
[23:31:41 CEST] <epifanio> and the size:  330x330 vs 1360x1024
[23:33:47 CEST] <kepstin> yeah, I suspect the size is the main issue
[23:36:24 CEST] <epifanio> how can i force the output to match this size? which is actually the original size of the png, a sample is:  http://epinux.com/hbc_img/selection/left/201503.20150619.181140656.204627.png
