[01:01:36 CET] <Hybridesque> Okay, I've cooked up my own ffmpeg for Ubuntu 15.10, and it works normally using x264 (after a bit of work of installing the necessary libaries on the transcoding server for mp3, aac etc etc)
[01:01:53 CET] <Hybridesque> It works fine on the x264, but when I try to use the qsv, it's not working.
[01:02:01 CET] <Hybridesque> I followed the compile instruction at https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
[01:02:18 CET] <Hybridesque> with exception of compiling the mfx dispatcher, and using --enable-libmfx
[01:02:50 CET] <Hybridesque> The logs I'm getting from ffmpeg are here: http://pastebin.com/MKUqHmyK
[01:50:17 CET] <Terra> Quick question with ffmpeg and rtmp streams (input), when the stream ends or if ffmpeg does not receive any data, it does not simply die. It continues running instead of just stopping and has to be manually killed
[01:50:22 CET] <Terra> Is there something I'm doing wrong?
[01:51:03 CET] <Terra> This is with nginx-rtmp as the rtmp server if that's any help.
[03:12:35 CET] <waressearcher2> Terra: hallo, wie geht's ?
[03:13:00 CET] <Terra> ? Sorry I only speek English.
[03:14:18 CET] <pepee> lol
[03:14:25 CET] <Terra> Though I got that much at least, I'm fine thanks :P
[03:30:58 CET] <_6U54N0_> does ffmpeg_2.0.4 has support to convert FLTP to S16?
[03:33:34 CET] <_6U54N0_> cause, i am trying to convert a decode frame in format FLTP to frame in format S16, but the result is wrong.
[03:44:39 CET] <Disturbed1_away> sup all....
[03:46:09 CET] <Disturbed1_away> need a little bit of help...
[03:49:55 CET] <Disturbed1_away> i just spent couple days getting ibm systemx3650(7979) working with centos6.7/64bit, with a nvida tesla s870... finally got everything working perfect, ( LOL ) so my next task is to try ffmpeg to use the gpu's.... after searching web for a bit i cant seem to recall the command to tell ffmpeg to use the gpu's.... here a copy of the code i'm using...  " for %%a in ("*.*") do ffmpeg -i "%%a" -s
[03:49:55 CET] <Disturbed1_away> 1920x1080 -c:v libx264 -strict experimental -crf 20 -c:a aac -ab 128k -ac 2 -ar 48000 -vprofile main -g 48 -threads 0 "newfiles\%%~na_master.mp4"
[03:49:55 CET] <Disturbed1_away>  " where would be the best place to put the gpu command?
[05:04:31 CET] <pepee> waressearcher2: hallo, wie geht's ?
[05:05:44 CET] <yongyung> When concatenating a couple of clips, is there a way to tell ffmpeg to create 2 seconds of black frames between them as a sort of "transition"?
[05:41:41 CET] <waressearcher2> pepee: es geht's, und selbst ?
[06:15:02 CET] <pepee> waressearcher2, es geht's. I just learned a bit of german today :P
[09:59:31 CET] <thomedy> hello is anyone working right now
[11:33:43 CET] <neXyon> is 48kHz the default sample rate of anything digital nowadays?
[15:45:34 CET] <Hybridesque> argh, this qsv thing on linux is going my nut.
[15:45:39 CET] <Hybridesque> *doing my nut
[15:50:24 CET] <BtbN> Just forget it exists, it's not worth it.
[15:56:30 CET] <Hybridesque> sodding Intel.
[19:26:46 CET] <senoo> hi, i want to blur a part on the center of my udp video input, how can i do this?
[19:35:27 CET] <waressearcher2> senoo: hallo, wie geht's ?
[19:36:24 CET] <microchip_> waressearcher2: english please
[19:42:24 CET] <Fjorgynn> hello
[19:42:32 CET] <Fjorgynn> I've got an hls mp3 audio stream
[19:42:39 CET] <Fjorgynn> how do I dump it?
[19:43:16 CET] <sylvain> hi
[19:43:42 CET] <Guest40501> any plans to make ffply available thru nacl ? might be very cool to create a new web browser plugin
[19:43:50 CET] <Guest40501> ffplay*
[19:44:43 CET] <Guest40501> https://code.google.com/p/native-client-ffplay/ found this but seems inactive :/
[20:06:38 CET] <Fjorgynn> I can't download
[20:38:23 CET] <Fjorgynn> [mpegts @ 004fe8c0] Non-monotonous DTS in output stream 0:0; previous: 60306610, current: 60301908; changing to 60306611. This may result in incorrect timestamp
[20:38:24 CET] <rjp421> http://cdn.c3voc.de/s1_native_hd.webm
[20:38:26 CET] <Fjorgynn> s in the output file.
[20:38:29 CET] <Fjorgynn> what does that mean?
[21:34:08 CET] <m4t> i'm struggling trying to get a gif input to loop for the duration of an audio input, when combining the two into a video
[21:34:46 CET] <m4t> trying like: ffmpeg -i giphy.gif -i *.m4a -strict -2 -loop 0 protein.mp4
[21:35:14 CET] <m4t> if i  move the "-loop 0" elsewhere, i.e. after the "-i giphy.gif" like "-i giphy.gif -loop 0", it says option loop not found
[21:35:59 CET] <furq> -loop is an input option
[21:36:03 CET] <furq> move it before the gif
[21:37:03 CET] <m4t> ya tried that too, thanks: -loop: No such file or directory
[21:37:16 CET] <furq> before -i
[21:37:46 CET] <m4t> yeah tried that too :( : Option loop not found.
[21:38:39 CET] <furq> i can't say i've tried with a gif but that should work fine for images
[21:42:16 CET] <m4t> hmm, -ignore_loop 0 works
[21:42:30 CET] <m4t> but it uh, seems to go on forever :-)
[21:42:39 CET] <furq> -shortest
[21:43:01 CET] <furq> that one's an output option
[21:44:10 CET] <m4t> perfect, thanks
[22:20:54 CET] <Terra> Asked yesterday but didn't get a reply. Does anyone have any idea why ffmpeg doesn't die/timeout whenever an RTMP stream stops or doesn't exist? It has to be manually killed.
[22:21:05 CET] <Terra> Not sure why or what I'm doing wrong
[22:24:26 CET] <JEEB> Terra: did the server die as well?
[22:24:49 CET] <Terra> ffmpeg -i rtmp://127.0.0.1/live/$uid -vframes 1 -an -s 220x130 -y /var/www/lthumb/$uid.png <- This is the command I use for generating screenshots but if it hits a stream that doesn't exist it just hangs
[22:24:51 CET] <JEEB> because rtmp(e) servers can basically have nothingness in the stream
[22:24:55 CET] <Terra> JEEB, nope.
[22:25:04 CET] <JEEB> so it's a valid stream, it just doesn't contain anything
[22:25:11 CET] <Terra> Yeah basically that.
[22:25:26 CET] <Terra> Is there a way to make it timeout if not actual data is recieved from it if that makes sense
[22:25:39 CET] <JEEB> probably not that limited, but there could be general timeouts
[22:25:49 CET] <JEEB> at least I remember finding one for UDP
[22:25:56 CET] <Terra> -timeout and -stimeout doesn't seem to do diddly
[22:26:18 CET] <Terra> huh udp timeout
[22:26:24 CET] <JEEB> for UDP it was in the URL, also make sure options you set are in the "decoder" side of things
[23:10:41 CET] <pepee> waressearcher2: hallo!
[23:12:15 CET] <waressearcher2> pepee: genug eigentlich
[23:12:49 CET] <pepee> lol
[23:17:38 CET] <_6U54N0_> porque ffmpeg se traga toda la memoria ram?
[23:18:26 CET] <_6U54N0_> me refiero, cuando se usa la liberia con C/C++ para decodificar video stream.
[23:20:29 CET] <pepee> _6U54N0_, has la pregunta en ingles
[23:21:24 CET] <_6U54N0_> no me gusta ese puto dialecto.
[23:22:19 CET] <pepee> ooh, we got a badass over here
[23:25:10 CET] <_6U54N0_> i dont know what did you say ... but ... if by flys  hdp.
[23:41:15 CET] <angeldorado> hello
[23:42:08 CET] <waressearcher2> angeldorado: hallo
[23:44:49 CET] <angeldorado> hi, trying to install ffmpeg static 32 bit on ubuntu studio
[23:45:19 CET] <angeldorado> not really sure how to do it. I tried ./ffmpeg on the folder it is downloaded but that just brought up a help menu it seems
[23:45:43 CET] <c_14> there's no installer
[23:45:47 CET] <c_14> just put it somewhere in your path
[23:46:12 CET] <angeldorado> so if I want to run ffmpeg -i <file>
[23:46:17 CET] <angeldorado> how do I do it?
[23:46:19 CET] <angeldorado> that does not work
[23:46:26 CET] <c_14> just put it somewhere in your path
[23:46:31 CET] <angeldorado> idk what you mean
[23:46:38 CET] <c_14> echo $PATH
[23:46:42 CET] <c_14> put it in one of those directories
[23:47:13 CET] <angeldorado> so do, echo $PATH <file directory>
[23:47:15 CET] <angeldorado> then run it?
[23:47:27 CET] <angeldorado> im a linux amateur
[23:47:52 CET] <c_14> put the ffmpeg binary in one of the directories listed when you run the command "echo $PATH"
[23:48:35 CET] <angeldorado> so echo $PATH calls a process from some other folder.
[23:50:22 CET] <c_14> mv ffmpeg $(echo $PATH | cut -d: -f1)
[23:50:32 CET] <rjp421> JEEB, im assuming ffmpeg will never support the udp rtmfp (p2p/multicast) protocol? i feel more people would use it if they knew how useful it could be
[23:50:39 CET] <angeldorado> echo $PATH /usr/local/bin/ffmpeg-2.8.4-32bit-static/ffmpeg  ffmpeg -i ending.mp4
[23:50:39 CET] <angeldorado> /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games /usr/local/bin/ffmpeg-2.8.4-32bit-static/ffmpeg ffmpeg -i ending.mp4
[23:52:08 CET] <angeldorado> this is too hard.
[23:59:53 CET] <angeldorado> ok, I've taken a breather now. What about software like openshot or blender that might use ffmpeg. how do I get those to access it?
