[00:06] <Steve132_> the cpu is intel
[00:06] <Steve132_> libraries version, I assume
[00:06] <Steve132_> based on nothing
[00:07] <Steve132_> same version of same OS
[00:10] <ubitux> then just try
[00:10] <Steve132_> ok
[00:10] <Steve132_> thank you so much for the help btw
[00:10] <ubitux> no problem
[00:13] <Steve132_> I'm broadcasting a udp stream with -f mpegts udp://localhost:2106
[00:13] <Steve132_> how do I capture that stream with ffmplay?
[00:14] <Steve132_> http://pastebin.com/bE4eUkEr
[00:14] <ubitux> don't you need a ffserver?
[00:15] <Steve132_> I don't know
[00:15] <ubitux> i'd say you have a ffserver
[00:15] <ubitux> you push stuff on it with ffmpeg
[00:15] <Steve132_> burek suggested just doing that
[00:15] <ubitux> and play the output with ffplay
[00:15] <ubitux> maybe you can skip the ffserver part, but no idea how
[00:16] <Steve132_> Well, let me guess: the ffserver is basicallly a fifo
[00:16] <Steve132_> that stores the data
[00:16] <Steve132_> right?
[00:17] <Steve132_> http://ubuntuforums.org/showthread.php?t=1156082
[00:18] <Steve132_> that also sora implies its not needed
[00:18] <Steve132_> *sorta
[00:18] <ubitux> can't help you there, too tired right now to think about something i never tried
[00:18] <Steve132_> sorry to be so dependant, but you've seriously helped a TON
[01:00] <hexsprite> How can I update the Orientation metadata when writing a MOV Quicktime file? http://wiki.multimedia.cx/index.php?title=FFmpeg_Metadata doesn't list it... wondering if there's a way that's not documented
[01:03] <ubitux> -metadata:v rotate=90 or something?
[01:18] <Steve132_> So, I wanted to make a patch to add hardware H264 to libavdevice/v4l2.c
[01:19] <Steve132_> Its pretty simple, and I did
[01:19] <Steve132_> (basically, just added     { PIX_FMT_NONE,    AV_CODEC_ID_H264,     V4L2_PIX_FMT_H264    }, to fmt_conversion_table[])
[01:19] <Steve132_> and it works for v4l2 capture
[01:19] <Steve132_> at least as far as I can tell
[01:19] <Steve132_> but the timestamps don't update
[01:20] <Steve132_> and the output file doesnt load correctly
[03:35] <aviazul> recently i compiled and installed ffmpeg, but it works only for me, doesn't work for other users (Ubuntu 12.04)
[03:35] <aviazul> how i do to it works to other users?
[03:56] <aviazul> anyone know how I do?
[11:46] <Steve132_> What is the right way to output to stdout?
[11:46] <Steve132_> I want to dump raw frame data
[11:47] <ubitux> video?
[11:47] <ubitux> or audio?
[11:56] <Steve132_> video
[11:56] <Steve132_> actually, something else must be wrong
[11:56] <Steve132_> because it seems to work when I do it on the command line
[11:57] <Steve132_> but when I open it with popen
[11:57] <Steve132_> it doesn
[11:57] <Steve132_> I'm to tired, its 5am
[11:58] <ubitux> anyway, you're looking for -c:v rawvideo
[11:58] <ubitux> assuming you set a pixel format
[12:01] <burek> Steve132_, release stdin/stdout
[12:01] <burek> it might help
[12:02] <Steve132_> release?
[12:02] <burek> stdin I mean
[12:02] <Steve132_> what do you mean?
[12:02] <burek> when you use the shell, stdin/stdout are automatically mapped to your terminal
[12:02] <burek> when you use it in a shell or cron job or (add your case here), you need to take care of those yourself
[12:03] <burek> terminal/keyboard*
[12:04] <burek> something like
[12:04] <burek> ffmpeg -i input.avi -vcodec rawvideo - </dev/null 2>/dev/null | another_process &
[17:06] <junctions> Hello guys, is anyone there?
[17:08] <D4rkSilver> No :D
[17:09] <junctions> hehe, sorry, didn't want to start typing away mootly
[17:10] <junctions> Here's my problem:
[17:10] <junctions> I'm trying to compile with --enable-libx264 after having downloaded and compiled the latest x264 on an ubuntu 11.04 but after doing a make/make install on the x264 going to the ffmpeg folder and running ./configure --enable-libx264 --enable-gpl it say "ERROR: libx264 not found"
[17:10] <junctions> *it says
[17:12] <JEEB> how did you compile x264?
[17:12] <JEEB> you probably want to add --enable-static to its configure
[17:12] <JEEB> also, you built it with yasm, right?
[17:13] <JEEB> otherwise it will not have simd optimizations and will be slow
[17:13] <junctions> hmm... I installed yasm through apt-get before all of this (ffmpeg required it)
[17:13] <junctions> and no, for the x264 I only ran ./configure
[17:14] <JEEB> yeah, you'll need to add --enable-static to get the library as well
[17:14] <junctions> okidokey, let's give that a try. oddly enough for another computer it worked just fine (I don't know if it's related but it has Ubuntu 12.04)
[17:15] <JEEB> probably not
[17:15] <JEEB> you probably had some older x264 around there
[17:15] <JEEB> (already installed via package management)
[17:18] <junctions> hmmm maybe, it's been a bit of a mess trying to find out how to have x264 support, I've uninstalled and installed the -dev part on some of these.
[17:18] <junctions> also had some trouble because I found on some forum the wrong suggestion to use --enable-encoder=libx264
[17:18] <junctions> note that ffmpeg will not give any error if you do this but no libx264 encoder will be installed either
[17:18] <junctions> anyways, the --enable-static worked, thanks! :)
[17:19] <JEEB> np
[17:20] <junctions> do you think I should file a bug report on it not giving any error for --enable-encoder=libx264?
[17:20] <JEEB> you should check the config.log output for that one, and if it really does something wrong then you might just want to do that
[17:21] <junctions> well it doesn't enable the encoder, isn't that a bug?
[17:21] <JEEB> go check config.log after running that
[17:21] <JEEB> and read through it
[17:22] <JEEB> depending on its contents, file the bug or not
[17:27] <junctions> well I did it, and then greped 'h264' on the config.log and all I see are references to the decoder, muxer, parser, hwaccel and others, nothing about the encoder
[17:28] <junctions> and nothing if I run grep ERROR
[17:28] <junctions> do you think I should look for something else before submitting a bug report about the --enable-encoder=libx264 option not doing anything?
[17:32] <JEEB> I'm not sure how that thing is supposed to work
[17:33] <JEEB> does it even try to test it if you look at config.log
[17:41] <junctions> nope, it doesn't say anything about it on the config.log
[17:42] <JEEB> and it doesn't say anything about the --enable-encoder=libx264 setting being wrong or whatever?
[17:44] <junctions> sorry, I just realized I was grepping h264 and not x264, it seems to recognize it as a variable but nothing more.... let me upload it to pastebin
[17:48] <junctions> pastebin.com/gw79T18X
[17:50] <junctions> I can also provide the config.log of --enable-libx264 if you want which does have a lot more mentions to x264 when grepped
[17:52] <JEEB> I guess --enable-encoder=libx264 does something different?
[17:52] <JEEB> not sure tho
[17:52] <JEEB> you could poke and make a trac issue about it
[17:52] <JEEB> (´
[17:59] <junctions> okidokie will do. my uneducated guess is that it used to work but then it was changed to be more uniform
[18:00] <junctions> anyways, thanks a lot JEEB :). Now edit some videos :)
[21:49] <iive> i'll remove some bans that are over 2 years old and have been set by DarkShikari
[21:51] <iive> I hope you don't mind. `md , ubitux , michaelni  ?
[21:55] <ubitux> sure
[22:11] <iive> I have no logs of the other bans. except 2 that i put myself. nmistal ban should stay. luisxp may be removed if you want, it looked like download bot.
[22:11] <iive> maybe the older ones should be removed too?
[22:14] <ubitux> ban can be re-added if necessary
[22:17] <iive> yes. nmistal jumped on my in another channel, that made me check the logs.
[22:17] <iive> on me...
