[00:44:04 CEST] <Filarius> so it seems issue was in short set of test data and my software closing stream before pushing all data to pipe. I think, with coder h264 it just not send "bad" data after last keyframe. [01:12:53 CEST] <fgfhdwfh> hello [01:13:19 CEST] <fgfhdwfh> when i execute : ffmpeg -i rtmp://184.72.239.149/vod -c copy dump.flv [01:13:30 CEST] <fgfhdwfh> i got always a connection refused error [01:13:45 CEST] <fgfhdwfh> can you help cause i cant found any thing on doc [01:14:36 CEST] <fgfhdwfh> it's an open rtmp im testing [01:19:04 CEST] <BtbN> well, the rtmp server refuses the connection [01:21:01 CEST] <fgfhdwfh> thank you for your reply [01:22:56 CEST] <BtbN> Well, it's not something ffmpeg can do much about, so not sure what you'd expect. [01:23:09 CEST] <BtbN> Just make sure you are using the right IP and port. [01:24:25 CEST] <fgfhdwfh> ok i understand [01:24:35 CEST] <BtbN> also, rtmp is usually a two part url [01:24:41 CEST] <BtbN> so it should be /vod/something [01:24:45 CEST] <BtbN> and not just /vod [01:25:20 CEST] <fgfhdwfh> can i use http stream url ? [01:25:26 CEST] <fgfhdwfh> ffmpeg -i http://218tv.ddns.net/ -c copy dump.flv [01:25:38 CEST] <BtbN> sure, if the server serves something ffmpeg understands [01:25:50 CEST] <BtbN> if it's a website with some (flash) player on it, no [01:27:26 CEST] <fgfhdwfh> i understand that i have to ask simply for rtmp url for the live stream so i can use it with ffmpeg [01:28:02 CEST] <BtbN> if the website plays it with some flash player, you should be able to extract it. If not from the source of the site, wireshark will find it. [01:44:19 CEST] <fgfhdwfh> thank you :) [01:46:07 CEST] <fgfhdwfh> i tracked rtmp link but on my server i have again connection refused error. So ill juste ask the stream administrator to give permission to my server ip [01:46:15 CEST] <fgfhdwfh> thank s again [02:46:55 CET] <Keridos> how can i convert an RGB input video into yuv444p output? [02:47:18 CET] <Keridos> currently I got wrong colors in output (looks like it interprets the input as BGR??) [02:52:08 CET] <furq> paste your command line and output [03:00:46 CET] <Keridos> furq: currently cannot, using custom ffmpeg output with obs, cannot get the full command line it launches [03:01:18 CET] <Keridos> just trying to find out how I can select a specific pixel format to interpret the input? [03:02:09 CET] <Keridos> so I do not want to specify pix_fmt for the output, but tell ffmpeg to interpret the input as a specific pixel format, even if it autodetects another one [03:02:21 CET] <furq> specify -pix_fmt before -i [05:24:32 CET] <kanzure> pp/win 79 [06:02:04 CET] <Ekho> probably just being blind but I cant find what flags are needed during configure to compile with alsa support, can somebody point me in the right direction? all i can find is that I need libasound [06:14:38 CET] <furq> Ekho: it's enabled by default [06:15:21 CET] <furq> if you don't have asoundlib.h or libasound then it'll be automatically disabled [06:23:23 CET] <Ekho> I have both asoundlib.h and libasound [06:40:44 CET] <Ekho> ignore me I'm an idiot an had a typo character in my alsa-lib prefix so ffmpeg couldnt find them [12:41:08 CET] <Filarius> funny, FFMpeg not writing all frames from StdIn if StdOut and StdError not closed... [12:49:02 CET] <crst> I'm not being able to figure it out properly when searching google or reading docs. What is the practical best solution with latest ffmpeg to convert a mp3 of a voice recording as small as bearable and applying highest quality conversion for the small filesize? [12:58:28 CET] <StephenS> is there an issue with opus git? It seems I cant clone it with: git clone http://git.opus-codec.org/opus.git [13:00:51 CET] <StephenS> hmm seems to work now, just takes a lot of time heh [15:30:52 CET] <TAFB2> Thank you FFMPEG :) Live streaming of the event yesturday went FLAWLESS! Thank you apple for HLS streaming too. Time lapse Zombie video: http://www.skyviewelectronics.com/zombie-walk-brooklin [15:30:59 CET] <kerio> \o/ [15:50:39 CET] <SchrodingersScat> nice [16:32:48 CET] <paule32> hello, how can i stream X server screen from 800x600 to 640x480 video only compressed? to nginx server port rtmp 1935 ? [16:44:37 CET] <paule32> ffmpeg -f x11grab -maxrate 128k -video_size 800x600 -g 60 -bufsize 1024k -f mp4 rtmp://192.168.178.80:1935/live [16:44:50 CET] <paule32> Output #0, flv, to 'rtmp://192.168.178.80:1935/live': [16:44:50 CET] <paule32> Output file #0 does not contain any stream [16:50:40 CET] <jkqxz> You need to tell it where to get the input from. It's probably X display :0, so add "-i :0" after "-f x11grab". [16:51:24 CET] <BtbN> you also won't have much fun with a 128kbps video stream. [16:52:37 CET] <jkqxz> It would take a while to converge, but for a mostly-static PC stream it might only be an incomplete disaster. [16:54:46 CET] <kerio> i have some 1.8mbps songs [17:14:52 CET] <paule32> jkqxz: what do you can point 1024k ? [17:15:22 CET] <paule32> is ffserver needed? [17:16:02 CET] <furq> no [17:16:22 CET] <paule32> how then rtmp to nginx? [17:17:21 CET] <furq> ffmpeg -f lavfi -i testsrc -c:v libx264 -f flv rtmp://192.168.178.80:1935/live [17:17:32 CET] <furq> if that works then your problem is probably the thing jkqxz said [17:18:47 CET] <paule32> unknown encode libx264 [17:19:21 CET] <furq> well that's a great start [17:19:54 CET] <furq> you probably want to start by getting an ffmpeg binary that has an h264 encoder [17:21:22 CET] <paule32> D.V.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [17:21:22 CET] <paule32> jens@kallup:/media/sdb1/e-learning/mov$ ffmpeg -codecs | grep h264 [17:22:10 CET] <furq> so you probably want to start by getting an ffmpeg binary that has an h264 encoder [17:26:34 CET] <paule32> Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 1532 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default) [17:38:43 CET] <paule32> runs [17:59:27 CET] <paule32> ./tests/../ffserver -f ffserver.conf [17:59:36 CET] <paule32> cancel running [18:02:13 CET] <paule32> https://paste.fedoraproject.org/465342/14778468/ [18:11:03 CET] <paule32> ok, ffmpeg works, for creating mp4 file [18:11:16 CET] <paule32> input is screen, output is file [18:11:28 CET] <paule32> so, how can i send to nginx? [18:11:42 CET] <paule32> or ffserver? [18:12:38 CET] <JEEB> never use ffserver unless you're ready to maintain or rewrite it [18:13:07 CET] <JEEB> if you want to stream, utilize a proper streaming server. icecast and a few others come to mind [18:13:40 CET] <paule32> i am under Linux [18:13:47 CET] <paule32> testing only, at the moment [18:14:26 CET] <paule32> i am c a programmer, so rewriting should not so hard ... [18:14:39 CET] <Mavrik> why on earth. [18:14:40 CET] <paule32> but i shall learn the basics .. [18:14:49 CET] <Mavrik> when you can use nginx-rtmp plugin. [18:15:04 CET] <JEEB> btw, did that thing support multiple profiles in any sane way? [18:15:13 CET] <JEEB> since flv IIRC is limited to a single thing or so? [18:15:39 CET] <Mavrik> nginx-rtmp? [18:15:39 CET] <bencoh> what is "that thing"? [18:15:45 CET] <Mavrik> or ffserver? :) [18:16:02 CET] <paule32> hold on guys [18:16:18 CET] <paule32> i test and then, i try to customize [18:16:21 CET] <bencoh> nginx-rtmp can stream out to hls, so ... yes, somehow [18:16:24 CET] <Mavrik> JEEB, nginx-rtmp supports HLS and DASH streaming which should be used instead of RTMP :P (yeah, dumb name I know :P ) [18:16:36 CET] <JEEB> yes, but the *input* is FLV in RTMP [18:16:47 CET] <JEEB> thus I'm not sure how you're supposed to input multiple video tracks to it [18:16:59 CET] <bencoh> JEEB: sure, but the point is you stream only one (highest) profile to it [18:17:01 CET] <paule32> ffmpeg -f x11grab -i :0.0+100,200 -framerate 7 -f mp4 /media/sdb1/e-learning/mov/feed1.mp4 [18:17:11 CET] <paule32> this create a mp4 file [18:17:17 CET] <Mavrik> JEEB, ahh, it's rather basic [18:17:23 CET] <Mavrik> it doesn't do switching IIRC [18:17:31 CET] <furq> JEEB: https://github.com/arut/nginx-rtmp-module/wiki/Directives#hls_variant [18:17:39 CET] <paule32> but i have to cut it (max size) to not override my hd [18:17:56 CET] <JEEB> furq: ahh [18:17:59 CET] <JEEB> that makes sense [18:18:16 CET] <bencoh> actually this hls_variant thing is far from being perfect, since GOP won't be aligned [18:18:40 CET] <JEEB> aligning GOPs isn't that hard anyways :P [18:18:43 CET] <bencoh> (unless you explicitely turn off scene cut) [18:18:54 CET] <paule32> guys, i am here :-) [18:19:14 CET] <furq> i'd expect to have to use fixed-size gops for adaptive streaming anyway [18:19:16 CET] <bencoh> JEEB: when using separate encoders it's not "hard" but it's kindof a waste ... but anyway :) [18:19:32 CET] <JEEB> furq: I don't but a lot of shit seems to expect it [18:19:48 CET] <JEEB> I was way too happy back with just HLS, where apple and others were all m'kay about it [18:19:52 CET] <bencoh> furq: you can do without it but you'll need synced encoders, somehow [18:19:54 CET] <JEEB> then I entered the lairs of the dragons [18:20:04 CET] <JEEB> and fuck those pieces of shit [18:20:27 CET] <JEEB> (excuse me for the language but that's what I got after interacting with certain vendors) [18:20:28 CET] <paule32> JEEB: i want to go the ffserver way [18:20:32 CET] <furq> streaming is fun [18:20:37 CET] <furq> please don't use ffserver [18:20:53 CET] <JEEB> paule32: which is pretty much "rewrite your own streaming server" [18:21:01 CET] <paule32> no [18:21:03 CET] <JEEB> because ffserver is dead and will not be alive [18:21:08 CET] <paule32> oh [18:21:08 CET] <furq> hopefully after 3.2 comes out i will never have to explain that again [18:21:18 CET] <furq> a beautiful dream~ [18:21:31 CET] <JEEB> a shot in the head and thrown into the back alley [18:21:37 CET] <paule32> so let me try the nginx way? [18:22:15 CET] <JEEB> paule32: just for your information - ffserver sounds probably good as a title but the thing would never work like you'd expect and you had to know its internals to do *anything*. also it required hacks all around because it liked to poke internals of the libraries instead of just utilizing them properly [18:22:25 CET] <furq> paule32: do you have libx264 yet [18:22:48 CET] <Mavrik> Is there anything cheaper than Wowza if you want to have a decent streaming server? [18:22:49 CET] <paule32> yes [18:22:59 CET] <paule32> ffmpeg is compiled and running [18:23:07 CET] <Mavrik> (set-it-and-forget-it variety with transcode and HLS/DASH/Smooth)? [18:23:11 CET] <furq> what's the problem then [18:23:24 CET] <JEEB> I am not sure if I would put transcode together with a media serving thing [18:23:29 CET] <paule32> i cant stream to my nginx server [18:23:36 CET] <JEEB> my preference is usually to separate the two [18:23:36 CET] <paule32> i get error [18:23:56 CET] <Mavrik> JEEB, yeah, mine too, but I get a lot of queries for smaller setups [18:24:12 CET] <Mavrik> Where people aren't really experts, have < 500 streams active and don't want too much hassle. [18:24:21 CET] <Mavrik> I usually recommended Wowza which works well enough for those cases. [18:24:25 CET] <JEEB> Mavrik: well nothing stops you from putting the two onto the same machine if you really want [18:24:55 CET] <JEEB> but yeah, I should start looking at solutions again [18:25:35 CET] <paule32> https://paste.fedoraproject.org/465427/77848319/ [18:25:37 CET] <paule32> look [18:26:12 CET] <BtbN> that's not a valid rtmp url. [18:26:23 CET] <BtbN> the name is missing [18:26:26 CET] <furq> that's also not the same x11grab invocation you just pasted [18:26:42 CET] <paule32> that differs, yes [18:26:50 CET] <paule32> that is, what i try, with nginx [18:29:19 CET] <paule32> https://paste.fedoraproject.org/465440/47784854/ [18:29:26 CET] <paule32> now, i get this [18:29:34 CET] <furq> -f flv [18:29:44 CET] <paule32> flash [18:29:45 CET] <paule32> ? [18:29:49 CET] <paule32> is dead [18:29:50 CET] <furq> rtmp uses flv [18:30:03 CET] <furq> also that's encoding to mpeg4, which is not x264 [18:30:34 CET] <paule32> can you give me correct cmd line? [18:30:36 CET] <paule32> thx [18:31:15 CET] <furq> replace -f mp4 with -f flv [18:31:28 CET] <furq> if you don't have x264 then it's going to encode to some garbage codec [18:31:38 CET] <paule32> ah ok [18:31:53 CET] <paule32> but the client players see mp4 ? [18:33:02 CET] <Mavrik> They shouldn't for live stream. [18:33:10 CET] <Mavrik> At least not for HLS. [18:33:43 CET] <paule32> https://paste.fedoraproject.org/465455/48792147/ [18:51:32 CET] <kerio> can't really livestream mp4 [18:52:17 CET] <JEEB> *objection* [18:52:33 CET] Action: JEEB inserts loads of text about segmented ISOBMFF [18:53:24 CET] <BtbN> in theory you don't even need to segment it. Just generate the moov atom early, and put it in the beginning. like DASH does [18:53:43 CET] <JEEB> DASH is just fragmented ISOBMFF [18:53:59 CET] <BtbN> it has one special element, which contains the header/moov atom. [18:54:00 CET] <JEEB> except you can have separate initialization segments with the parameter sets etc [18:54:11 CET] <BtbN> and if you cat header seg1 seg2 ... you get a valid file [18:54:14 CET] <JEEB> you could as well have them in the beginning of each normal segment [18:54:14 CET] <BtbN> so you can stream that [18:54:21 CET] <Mavrik> JEEB, can we agree on "streaming MP4 is a sin and DASH an abomination" ? :P [18:54:40 CET] <JEEB> no? it's less bad than HLS because MPEG-TS eats bandwidth? [18:54:41 CET] <kerio> long live hls [18:55:16 CET] <JEEB> and I still think fragmented ISOBMFF is the least bad ingest format for HTTP streaming remuxing [18:55:17 CET] <BtbN> that 1 or 2 % of overhead doesn't matter too much [18:55:52 CET] <paule32> hey BtbN nice to see you [18:56:14 CET] <kerio> how did we end up with https/ip [18:56:15 CET] <paule32> did you code in pascal, anymore? [18:56:28 CET] <JEEB> kerio: people wanted to use their HTTP infra [18:56:35 CET] <JEEB> like load balancers and caching [18:56:40 CET] <JEEB> so, uh, here we area [18:56:57 CET] <paule32> JEEB: is that output normal? [18:56:59 CET] <paule32> https://paste.fedoraproject.org/465455/48792147/ [19:01:17 CET] <paule32> the argument -b 128k does nothing [19:01:39 CET] <paule32> what is -crf 20 ? [19:04:15 CET] <paule32> and -vcodec libx264 [19:04:31 CET] <paule32> give me unknown codec 'libx264' [19:05:05 CET] <JEEB> then you built without x264 [19:05:06 CET] <JEEB> simple as that [19:10:12 CET] <paule32> when i remove the option, i get, muxer is not streamable [19:11:38 CET] <paule32> what means "past duration to large" ? [19:12:56 CET] <paule32> will this debug output store in log file? [19:13:24 CET] <paule32> haleyulja, then happy streaming [19:14:05 CET] <TheXzoron> how would I record from multiple audio input devices in ffmpeg [19:16:05 CET] <TheXzoron> ffmpeg -f alsa -ac 1 -ar 44100 -i webcamrate -f alsa -ac 2 -ar 48000 -i looprecvol /tmp/test.wav [19:16:21 CET] <TheXzoron> is what I'm trying but it does not get the webcam mic [19:16:34 CET] <TheXzoron> but it does individually [19:20:53 CET] <Filarius> -i input1 -i input2 -map 0 -map 1 output [19:21:47 CET] <Filarius> if you input is have several tracks, like video and audio, then -i input1 -i input2 -map 0:a -map 1:a output [19:22:52 CET] <Filarius> also works -map 0:0 -map 0:1 here u just how track number, audio must be 1 and more [19:23:00 CET] <Filarius> *show [19:24:46 CET] <TheXzoron> ffmpeg -i alsa -i alsa -map webcamrate -map looprecvol /tmp/test.wav this didn't work so [19:30:00 CET] <TheXzoron> ok I got it it was ffmpeg -f alsa -ac 1 -ar 48000 -i webcamrate -f alsa -ac 2 -ar 44100 -i looprecvol -map 0 -map 1 [19:34:51 CET] <TheXzoron> but [19:34:57 CET] <TheXzoron> no it wasn't [19:43:14 CET] <TheXzoron> it doesn't play properly [19:45:41 CET] <TheXzoron> oh I see [19:45:50 CET] <TheXzoron> one source is 1 channel and the other has 2 channels [19:46:02 CET] <TheXzoron> and it keeps trying to switch between channels for some reason [19:46:06 CET] <TheXzoron> why [19:46:23 CET] <Filarius> ffmpeg -f alsa -ac 1 -ar 48000 -i webcamrate -f alsa -ac 2 -ar 44100 -i looprecvol -map 0 -map 1 out.mkv [19:47:35 CET] <Filarius> and I do not see how you can put 2 audiostreams in one wav file [19:47:58 CET] <TheXzoron> I didn't know wave was mono only [19:48:29 CET] <Filarius> mono/stereo is audio track parameters [19:49:25 CET] <Filarius> and i'm not sure what FFMpeg will do if you try to mux 2 tracks to WAV without make it know what it is left and right channels [19:49:54 CET] <paule32> so, i have pipe the output 2> /dev/null [19:50:04 CET] <paule32> how can i see, if something wrong?

[21:54:48 CET] <steve__> Hi, I just purchased a Garmin DashCam that encodes GPS inside the MP4 files it outputs. I believe its being stored using SEI messages. Does anyone know if/how I can use FFMPEG to export that data? [22:03:27 CET] <paule32> i can't find codec asf for vlc linux [22:03:54 CET] <paule32> i run into error on vlc client side: undf not supported [23:50:59 CET] <deweydb> fhey guys [23:51:02 CET] <deweydb> -f [23:57:09 CET] <deweydb> i've got a file that is in MTS format. usually my scripts use ffprobe -of json -show_streams ... to pull out metadata information, most importantly the number of frames in the video. i get this from a value in the video stream with the key 'nb_frames' but this MTS file doesn't have that populated. Is there some other way of getting the precise number of frames, maybe from sort of magical multiplication of ts and something [23:57:09 CET] <deweydb> else? this is the stream in questions metadata: http://pastebin.com/BRPDDEZi [23:57:57 CET] <deweydb> another stream (any non MTS file i have encountered looks like this, i.e. it has nb_frames): http://pastebin.com/ZrBhbygJ [23:58:25 CET] <c_14> Does your command have -count_frames ?
