[00:57] <Zeranoe> Does anyone know if FFmpeg supports multi thread encoding with vp8/vpx?
[09:06] <Semestert> what is command to join  2 splitted .mp4 file
[09:53] <s0126h> does ffmpeg support joining  splitted .mp4 video files?
[11:00] <lanceio> JEEB, you there?! :D
[11:00] <lanceio> I got it to work perfectly! xD
[11:01] <lanceio> all I did was compile from scratch, and then I had to toy around a little with the excerpt you gave me, and it worked perfectly! :)
[12:50] <lanceio> the -crf option should be higher for more compression? or lower for more compression?
[12:58] <lanceio> compression makes the video smaller in size right?
[13:14] <JEEB> gotta love people leaving within a minute or two
[13:56] <burek> s0126h, try concat: protocol
[14:33] <bartus> hi there ! have problem witch first pass encoding log file.
[14:33] <bartus> when add -flag mv4 flag to firs pass, ffmpeg produce empty log file :/
[14:38] <burek> bartus,
[14:39] <burek> can you please use pastebin.com, to show your command line and its output?
[14:48] <bartus> ok, give me a moment ...
[14:49] <bartus> http://pastebin.com/1FQekDtf
[14:50] <bartus> use this script to convert video for my old iriverx20.
[14:52] <bartus> need to remove '-flags' switch from first pass to make it work.

[14:58] <kmk234> how do i solve this problem
[15:00] <kmk234> anybody
[15:00] <kmk234> help
[15:00] <burek> bartus, there is no output text there
[15:00] <kmk234> help
[15:00] <burek> in your paste
[15:00] <burek> kmk234, don't spam that much
[15:00] <burek> if someone knows the answer, he/she will answer
[15:01] <kmk234> so did you see my message
[15:01] <burek> kmk234, next time use pastebin
[15:01] <burek> to avoid flooding the channel with logs
[15:02] <kmk234> do you know what is going on with the ffmpeg
[15:02] <burek> also, most probably you need make distclean
[15:02] <burek> and repeat the whole process
[15:02] <burek> (ffmpeg too)
[15:03] <kmk234> ok i will try again
[15:06] <bartus> burek, gave me a moment...
[15:06] <burek> I did :)
[15:07] <bartus> burek, here's output from previously showed script '-flags mv4+aic' included in first pass, as it's shows ; http://pastebin.com/60y76T5g
[15:08] <bartus> ffmpeg2pass-0.log is empty, as i mention before :/
[15:10] <burek> bartus, 1st pass is analysis only
[15:11] <burek> hmh..
[15:11] <burek> try: -flags "+mv4 +aic"
[15:12] <bartus> burek, trying ...
[15:16] <kmk234> thanks it work
[15:16] <burek> :beer: :)
[15:18] <stickyboy> 1920x800 is what, 800p?
[15:23] <bartus> burek, [NULL @ 0x7ffc60] [Eval @ 0x7fff9f4bae40] Undefined constant or missing '(' in 'mv4'
[15:23] <bartus> [NULL @ 0x7ffc60] Unable to parse option value "mv4 +aic"
[15:23] <bartus> [NULL @ 0x7ffc60] Error setting option flags to value +mv4 +aic.
[15:24] <LexSfX> stickyboy: it's 1920×800.  there's no need to shorten it, causing ambiguity.
[15:25] <burek> bartus, try -flags "+mv4+aic"
[15:25] <burek> without blanks
[15:25] <burek> stickyboy,
[15:25] <burek> can you please use pastebin.com, to show your command line and its output?
[15:26] <bartus> burek, now it works ;] thanks !
[15:26] <stickyboy> burek: The output of ffmpeg -i?
[15:27] <stickyboy> LexSfX: Ok.  So "1080p" and others are more useful to marketing?
[15:28] <stickyboy> burek: http://pastebin.com/jN19Qgns
[15:28] <LexSfX> "1080p" isn't really useful for marketing.  people bought high-resolution 1920×1440 monitors and suchlike long before "1080p" and "720p" were tossed around.
[15:29] <stickyboy> LexSfX: You're saying it's not useful.  Period. :)
[15:29] <LexSfX> right.  it's more ambiguous than simply providing both dimensions
[15:30] <LexSfX> it's better to say "1920×1080 monitor"
[15:30] <stickyboy> Ok.  Because from both dimensions you can imply aspect ratio?
[15:30] <stickyboy> I take it that's the more important piece of info; whether it's wide screen or whatever.
[15:30] <LexSfX> you could even include the aspect ratio for those who don't want to do the math: "1920×1080 16:9 monitor"
[15:31] <burek> stickyboy, I think your video might be interlaced
[15:31] <LexSfX> or go even further: "1920×1080 16:9 standard widescreen HD monitor"
[15:31] <stickyboy> burek: Ah, maybe that explains my problem.
[15:31] <stickyboy> I'm troubleshooting hardware-accelerated h264 on an Android port I'm working on.
[15:32] <stickyboy> So I'm just testing with various videos I have laying around.
[15:41] <DelphiWorld> hello folks
[15:45] <DelphiWorld> http://dpaste.com/752524/
[15:45] <DelphiWorld> any error in this FFServer configuration?
[15:51] <DelphiWorld> in sdp i have address of 0.0.0.0
[16:13] <DelphiWorld> anyone ?
[16:17] <burek> DelphiWorld, what error do you get?
[16:18] <DelphiWorld> burekno error at all, just sdp file contin 0.0.0.0 ip
[16:18] <DelphiWorld> and audio/video port is null
[16:18] <DelphiWorld> 0
[16:18] <DelphiWorld> burek, sec:)
[16:18] <burek> DelphiWorld, did you check the sample ffserver config file?
[16:18] <DelphiWorld> burek: yes, did you see mine?
[16:20] <burek> just access your stream using: ffplay http://localhost:8090/test1.mpg
[16:20] <DelphiWorld> burek, but i want to access it using iOs ;)
[16:21] <burek> ios?
[16:21] <burek> or ffplay rtsp://localhost:554/test1.mpg
[16:21] <DelphiWorld> burek: iOs... iPhone/POD/PAD/
[16:22] <burek> oh :) idiotOS :)
[16:22] <burek> well, good luck with that :)
[16:22] <DelphiWorld> burek: ;)
[16:22] <DelphiWorld> burwhy?
[16:23] <DelphiWorld> burek: any reason? :|
[16:23] <burek> for?
[16:24] <DelphiWorld> burek: for iOs;)
[16:24] <burek> no reason, only drawbacks :)
[16:25] <burek> but it's offtopic here ;)
[16:25] <DelphiWorld> burek: :P
[18:02] <swick> is there a way to use x11grab with fullscreen? it only shows black with "ffmpeg -f x11grab -r 30 -s 1440x900 -i :0.0 test.mkv"
[18:32] <burek> swick,
[18:32] <burek> can you please use pastebin.com, to show your command line and its output?
[18:32] <burek> and what is your DISPLAY env var?
[18:39] <burek> up until we are still young..
[18:57] <DelphiWorld> burek: re
[19:03] <DelphiWorld> i want to stream a multicast udp stream to a mp4 AAC/H.264 using FFServer any idea ?
[19:15] <burek> DelphiWorld, yes :) start ffserver, start ffmpeg and then stream :)
[19:15] <DelphiWorld> burek: ;)
[19:15] <burek> you have an example in the sample config file
[19:15] <burek> just read it
[19:16] <burek> and mp4 is not a streaming format
[19:16] <burek> afaik
[19:16] <burek> use mpegts or flv
[19:16] <DelphiWorld> burek: so what's mp4?
[19:16] <burek> file format?
[19:17] <JEEB> it's a container that by default needs an index that can only be made after the file has been fully created
[19:17] <s0126h> does ffmpeg support joining  splitted .mp4 video files?
[19:17] <JEEB> although if you use the fragments feature in mp4, you will be able to have small indexes around the file
[19:18] <JEEB> which will enable you to stream it, but I'm not sure what would support it :D
[19:18] <DelphiWorld> JEEB: thx;)
[19:18] <burek> s0126h, already told you, try concat:
[19:18] <s0126h> concat?
[19:19] <JEEB> I don't think the concat filter in ffmpeg properly reads the input and concats, it's just the same if you piped the raw data together and fed it to the ffmpeg's parsers
[19:19] <burek> http://ffmpeg.org/ffmpeg.html#concat
[19:22] <DelphiWorld> JEEB, burek: anyway, my case is the following
[19:22] <DelphiWorld> i have a group of multicast channels
[19:22] <DelphiWorld> i want to be able to transcode them and put them on a rtp of http streamable format to be able to watch using my iphone on the go. that's all
[19:22] <JEEB> I think iphone wants hls streaming
[19:23] <JEEB> which is mpeg-ts + H.264/AAC over http, plus some extra stuff
[19:23] <burek> DelphiWorld, sorry, I don't use nor like idiotOS :)
[19:23] <DelphiWorld> burek: ok, i will tel you something
[19:23] <burek> wait for other people to come and help you
[19:23] <DelphiWorld> burek: can you seat with me and speak what's on mobile scereen all the day ?
[19:23] <burek> don't have time :/
[19:23] <burek> g2g :S
[19:24] <DelphiWorld> burek: yes
[19:24] <DelphiWorld> burek:  but ios speak for me
[19:24] <DelphiWorld> burek: i am blind DUDE
[19:25] <JEEB> DelphiWorld, you will basically want to take that multicast input and stream it via HLS for iOS devices (and possibly android 3.x+)
[19:25] <JEEB> not sure about ffmpeg, but at least VLC can do it afaics
[19:25] <DelphiWorld> JEEB: what's hls?
[19:25] <JEEB> unfortunately I have no experience in that :)
[19:25] <JEEB> <JEEB> I think iphone wants hls streaming
[19:25] <JEEB> <JEEB> which is mpeg-ts + H.264/AAC over http, plus some extra stuff
[19:25] <JEEB> the extra stuff being some kind of playlist with urls etc.
[19:28] <DelphiWorld> JEEB, i did say i don't know hls or hlr...
[19:28] <JEEB> yes, which is why I gave you a short comment on it
[19:28] <JEEB> you would have to see if whatever you use supports it and so forth by yourself, unfortunately
[19:31] <DelphiWorld> LOL
[19:31] <DelphiWorld> nothing hlr on google;)
[19:31] <JEEB> why hlr?
[19:31] <JEEB> hls is what you most probably would need
[19:33] <DelphiWorld> HELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
[20:17] <concrete_> Does anyone know about the ALSA xrun buffer errors while using ffmpeg ?
[21:35] <funkster> getting a "-q:a unreconigzed" on a new server but older one doesnt give that ffmpeg error - slightly different versions though - anyone have any insight
[22:26] <DelphiWorld> saste: yo;)
