[00:09] <michaelni> pcbb, jpeg over RTP is recent make sure you have the latest ffmpeg also if it doesnt work please provide more information, full output from ffmpeg and a reproduceable testcase
[00:11] <pcbb> michaelni Yah ... my ffmpeg is updated... well the RTP JPEG is a little different. http://tools.ietf.org/html/rfc2035      "...A special header is added to each packet that immediately follows the RTP header..."
[00:12] <pcbb> I want know if FFMPEG can parse this ...
[00:12] <pcbb> and give me a full jpeg
[00:19] <michaelni> pcbb, rfc2035 / 2435 should be supported
[00:23] <pcbb> michaelni I can't find any topic about my question that is "how convert the AVPacket received from jpeg rtsp to jpeg file"
[00:24] <michaelni> pcbb, the demuxer should provide you with a valid jpeg
[00:25] <michaelni> pcbb, also if you want to debug this yourself, maybe look at libavformat/rtpdec_jpeg.c
[00:25] <michaelni> and the jpeg decoder to see where it fails ...
[00:37] <ubitux> http://cubieboard.org/  "NEON"
[00:38] <ubitux> might be interesting to bookmark for later
[00:39] <pcbb> michaelni
[00:39] <pcbb> what is the difference of muxer vs demuxer?
[00:39] <ubitux> respectively write packets and read packets
[00:41] <pcbb> COOL
[00:41] <pcbb> I've the AVInputFormat... how configure the demuxer?? I can't see this in the documentation
[00:41] <ubitux> look at the doc/examples
[00:42] <pcbb> ok
[00:42] <pcbb> I'll see
[00:42] <ubitux> btw, this is the development channel, not the user/api support channel
[00:44] <pcbb> sorry
[01:02] <pcbb> ubitux don't have examples about demuxers and don't have many informations on documentation
[01:02] <pcbb> -.-

[03:30] <oneal> Hello, I want to know are there any body who are focusing on parallizing the video transcode pipeline. eg, the decode stage, filter processing stage and encode stage are proccessing in a different threads. 
[03:32] <Compn> theres some people
[03:32] <Compn> decode and encode are both threaded 
[03:32] <Compn> i dont know if filters are being threaded yet
[03:32] <oneal> Yes, but the filter stages is not
[03:33] <Compn> have to talk to saste, see if the api is there yet
[03:33] <Compn> i think saste is still working on porting filters atm.
[03:33] <Compn> ubitux may also know
[03:33] <oneal> who is focusing on this. are there some patchs submitted .
[03:35] <oneal> Compn, you mean ubitux and saste know about this.
[03:36] <Compn> i mean saste is the filter guy
[03:36] <Compn> so he knows the api
[03:36] <Compn> saste = stefano 
[03:36] <Compn> if you want to mail him...
[03:37] <oneal> Thanks, Compn, I want to talk about this with him
[03:38] <Compn> are you interested in contributing ?
[03:38] <ubitux> i'm having fun with lavfi, but nothing about //
[03:38] <Compn> or just really want that feature?
[03:39] <oneal> Yes,I'm doing some optimizations on ffmpeg, 
[03:39] <oneal> accelerating the filter processing and the pipeline.
[03:43] <oneal> the current case in ffmpeg is the current frame is proccessed by the filter, then this frame will be encoded, after encoding the current frame, then the filter only process the next frame.  
[03:49] <ubitux> http://ubitux.fr/pub/pics/ebur128.png \o/
[03:49] <ubitux> let's add some fancy info now
[04:02] <oneal> ubitux, I don't catch what's your mean.
[04:05] <ubitux> i'm just talking for myself :p
[04:05] <oneal> hmm, I see.

[05:45] <ubitux> if i want to know if a given channel layout has a LFE and get the id of the channel, how am i supposed to do that?
[05:46] <ubitux> i'm checking (channel_layout & 1ULL<<i) == AV_CH_LOW_FREQUENCY right now (for each channel i)
[05:46] <ubitux> is the LFE always supposed to be at the same id?

[07:45] <ubitux> http://lucy.pkh.me/loudness.webm :)
[07:57] <ubitux> i need to add print text, but i'm unsure about how to achieve that
[07:57] <ubitux> i don't like very much adding a fontconfig dependency
[07:57] <ubitux> since it's basically to print numbers and a few ascii letters
[07:58] <ubitux> it sounds almost better to me to use a bintext encoder
[08:54] <ubitux> michaelni: decode_mb_b() returns void
[08:54] <ubitux> so your last cavsdec doesn't look ok
[08:55] <ubitux> +patch
[12:19] <CIA-56> ffmpeg: 03Carl Eugen Hoyos 07master * r20361bcc26 10ffmpeg/configure: The TrueHD decoder needs the MLP parser.
[13:24] <michaelni> ubitux,  theres a return AVERROR_INVALIDDATA in decode_mb_b() so the chnage to int was needed

[14:54] <CIA-56> ffmpeg: lavfi/amerge: fix input pad name behaviour.
[14:54] <CIA-56> ffmpeg: This fixes two problems:
[14:54] <CIA-56> ffmpeg:  - the invalid pad.name stack pointer after init() ends
[14:54] <CIA-56> ffmpeg:  - the duplicated name for all inputs
[14:58] <ubitux> michaelni: i didn't see you actually fixed it
[14:59] <ubitux> sorry, i was refering to 7ea5dbcb
[14:59] <ubitux> but you fixed it quickly
[15:02] <saste> ubitux: can you compare amerge with amix?
[15:02] <saste> what are the main differences?
[15:02] <saste> at least i see that amix has some options which we lack in amerge
[15:03] <ubitux> mmmh
[15:03] <saste> getting the longest stream it is a nice feature indeed
[15:03] <ubitux> no idea
[15:03] <ubitux> i think Nicolas really doesn't like amix for several reasons
[15:03] <ubitux> but i don't remember them very well

[15:34] <CIA-56> ffmpeg: configure: Don't try to enable the log2 function on msvcrt
[15:34] <CIA-56> ffmpeg: Some msvcrt versions (the static 64 bit libc in MSVC 10) have
[15:34] <CIA-56> ffmpeg: a log2 function, but there is no declaration for it in the headers.
[15:34] <CIA-56> ffmpeg: Therefore, the normal configure check might find it, but it can fail
[15:34] <CIA-56> ffmpeg: during build or at runtime, depending on whether implicit function

[16:28] <saste> can you comment on it?
[16:28] <ubitux> saste: did you get my PV?
[16:28] <saste> i was trying to write a rawvideo AVI and the generated file fails to be sanely recognized
[16:41] <michaelni> saste, i need to know more details to fix it ...
[16:45] <michaelni> Retransmit: saste, i need to know more details to fix it ...
[16:46] <saste> michaelni, try this command
[16:47] <saste> michaelni, ffmpeg -f lavfi -i testsrc=d=5 -codec:v rawvideo -pix_fmt rgb24  -y out.avi
[16:47] <saste> then ffprobe/ffplay/vlc out.avi
[16:48] <Daemon404> question: why does mt-work/ still exist?
[16:48] <saste> avformat_write_header() sets codec_tag to 0, then the AVI demuxer picks bgr24 when guessing the pixel format
[17:17] <Daemon404> also, in here, nevcairiel, ffmpeg only needs a few more patches to work with msvc
[17:17] <Daemon404> one is annoying though.
[17:19] <nevcairiel> whats the annoying one?
[17:19] <Daemon404> for the host-tool print-options
[17:19] <Daemon404> its a makefile and/or configure thing
[17:19] <Daemon404> i think
[17:37] <saste> how can i check which headers are missing in a .c file?
[17:37] <saste> the equivalent of make checkheaders
[17:39] <Daemon404> is andoma still around?
[17:39] <Daemon404> maybe astrange knows
[17:40] <saste> Daemon404: andoma, astrange
[17:40] <saste> can't say them here since ages
[17:40] <saste> *can't see
[17:41] <Daemon404> saste, i want to send an RFC to the ML to rm -r mt-work/, and i thought about moving yuvcmp.c to tools/
[17:41] <Daemon404> but it has no license
[17:41] <Daemon404> just "written by <name>"
[17:41] <Daemon404>  * originally by Andreas Öman (andoma)
[17:41] <Daemon404>  * some changes by Alexander Strange
[17:41] <saste> ah ok
[17:41] <saste> send the patch and keep the no-license
[17:42] <Daemon404> it's just an RFC
[17:42] <Daemon404> and comments we shall get
[17:42] <saste> you may CC one or both of them
[17:42] <Daemon404> mt-work is dead code otherwise

[19:28] <Daemon404> wat
[19:28] <nevcairiel> must've turned it off for ffmpeg-devel

[19:28] <Daemon404> oh that
[19:28] <Daemon404> its old yes
[19:28] <nevcairiel> i mean, it is the libav patchwork
[19:28] <Daemon404> i was gonna set up patchwork

[19:58] <Daemon404> anyone very versed in va_list stuff? (this is for cmdutils.c)
[19:58] <Daemon404> i.e. msvc does not have va_copy
[19:59] <ubitux> #define va_copy(a,b) a=b ?
[19:59] <Daemon404> thats not portable
[19:59] <Daemon404> to anything but msvc
[19:59] <ubitux> well, just for msvc
[19:59] <Daemon404> seems rather ugly
[19:59] <ubitux> don't we have a place for all that stuff?
[20:00] <Daemon404> iirc va_copy is nto required
[20:00] <Daemon404> to write portable code
[20:00] <Daemon404> id rather just get rid of it if possible
[20:00] <ohsix> all it does is copy the initial pointer, just like a=b
[20:00] <Daemon404> ohsix, thats not true for all systems
[20:01] <ohsix> fo course, if the stack layout is interesting it can't be done with just a pointer
[20:01] <ubitux> Daemon404: va_copy is a c99 feature, why not make the c99toc89 handle that simple case?
[20:02] <Daemon404> is it -actually- c99?
[20:02] <Daemon404> as in the spec?
[20:02] <ubitux> according to the man :p
[20:02] <Daemon404> looks like it
[20:02] <ubitux>        The va_start(), va_arg(), and va_end() macros conform to C89.  C99 defines the va_copy() macro.
[20:02] <Daemon404> hmmm
[20:02] <Daemon404> interesting
[20:02] <Daemon404> might be better...
[20:02] <ohsix> maybe you don't get c99 on interesting stacks? :D
[20:03] <ohsix> there's not much reason to need va_copy, in any situation where you might you could change the code so you don't
[20:03] <ubitux> OTOH, doing this in c99toc89 won't generate valid c89 code on all systems
[20:03] <Daemon404> yeah
[20:03] <Daemon404> libav is actually running a converter+gcc instance
[20:03] <Daemon404> to test such things
[20:03] <ubitux> still, it looks like it belongs there
[20:04] <ubitux> we use va_copy in bprint api too

[20:04] <Daemon404> ubitux, not anymore
[20:04] <Daemon404> or, soon
[20:04] <ohsix> zomg that had your in real life earth geolocation in the url
[20:05] <ubitux> ok
[20:05] <Daemon404> /care
[20:05] <Daemon404> its my workplace
[20:05] <Daemon404> everyone knows where i work
[20:06] <Daemon404> ffmpeg likely needs around 4 patche to be msvc compatible
[20:06] <Daemon404> postproc fix, which is in v2 and awaiting michaelni 
[20:06] <ohsix> va_end with no start? also you only need to copy the va if you want to repeatedly do va_arg, then do it again
[20:06] <ohsix> so if there are 3 arguments, va_arg 1, 2, or 3; then use the copy to reset the sequence
[20:06] <Daemon404> ohsix, yeah...
[20:07] <Daemon404> im thinking it isnt even needed
[20:07] <Daemon404> so fixes needed: cmdutils, ffmpeg.c, postproc, bprint
[20:07] <ohsix> invoking a function with va_list isn't going to change it's value :D
[20:07] <Daemon404> ohsix, should i just be able to use va_start
[20:07] <Daemon404> shouldnt*
[20:07] <ohsix> i don't think you even need that, va_start is to set up va_arg
[20:08] <ohsix> i think va_start just assures it's not in a register
[20:08] <Daemon404> then wtf is ca_copy even doing
[20:08] <ohsix> but a) that code looks wrong anyways b) probably don't need to even touch it
[20:08] <Daemon404> s/ca/va/
[20:09] <ohsix> copying a pointer
[20:09] <Daemon404> but why
[20:09] <ohsix> think of the state in strstr, it's sort of the same thing
[20:09] <Daemon404> fun...
[20:09] <ohsix> va_arg just advances the pointer and returns what it pointed at
[20:09] <Daemon404> we arent modifying it anyway
[20:09] <ohsix> so if you're going to start again, you need the starting point
[20:09] <Daemon404> so i dont see why va_copy is needed at all
[20:10] <ohsix> right, it's not; but i'd check the specifications just the same, it's very weird to call va_copy then va_end, so much that i'd be looking at the specs anyways ;]
[20:10] <Daemon404> or i could just ask nicolas
[20:10] <Daemon404> who wrote it
[20:11] <ohsix> the man page says each invocation of va_copy must be matched by a va_end
[20:11] <Daemon404> it is
[20:11] <ohsix> right
[20:11] <Daemon404> also
[20:11] <Daemon404> i just notice
[20:11] <Daemon404> it uses fputs
[20:11] <Daemon404> how evil
[20:12] <ohsix> interesting, va_start can allocate memory to move the arguments out of registers on some systems too
[20:13] <ohsix> so you need the va_copy if you are going to pass va_list to another context :<
[20:13] <ohsix> i've got some code to fix that only coincidentally works at the moment :>
[20:13] <Daemon404> ;p

[20:20] <brimestone> hey guys, what causes my ffmpeg to error out when stiching sequencial images to video...
[20:20] <brimestone> http://pastebin.com/yhnnPYkX
[20:20] <ubitux> -f image2 -i foo%d.jpg ?
[20:21] <ubitux> your ffmpeg is old btw, we don't use svn since& well, prehistoric times
[20:21] <ubitux> (this is a user question)
[20:21] <Compn> brimestone : what are you doing in this developer channel with a user question ?
[20:21] <Compn> get out!
[20:21] <ubitux> haha
[20:21] <brimestone> sorry.. user doesnt know too 
[20:21] <Compn> get out get out get out! dexter is a cookie!
[20:22] <Daemon404> brimestone, uh
[20:22] <ubitux> cookie? *_*
[20:22] <Daemon404> put the filename in single quotes
[20:22] Action: Daemon404 wonders if teh shell is escaping it
[20:23] <ubitux> imo this is just missing the image2 format
[20:23] <ubitux> cause the globbing is likely part of this but well
[20:23] <Daemon404> hehe
[20:28] <brimestone> didn't work
[20:28] <brimestone> im re-compiling the new ffmpeg
[21:03] <michaelni> saste, i see no difference from before 75a9479b393a02ffa03436f275ad2b91bd2acd26 and HEAD both show wrong colors with avi output
[21:04] <saste> michealni: uhm yes i see
[21:04] <saste>  //the current rawvideo encoding system ends up setting the wrong codec_tag for avi/mov, we override it here
[21:04] <saste> does it means that AVI muxing is broken with rawvideo?
[21:05] <saste> basically we're not setting the codec tag, so there is no way the AVI demuxer can guess which is the correct pixel format
[21:09] <michaelni> rgb is normally stored with codec_tag 0 in avi and using a bit per pixel field to identify the kind
[21:11] <saste> michaelni, so do you have an idea why rgb24 is probed like bgr24?
[21:12] <saste> i didn't try with other pixel formats, to say the truth
[21:13] <michaelni> do we have a valid avi sample that contains rgb24 ?
[21:13] <michaelni> if so its probably not hard to implement support for it
[21:35] <saste> michaelni: ffmpeg -f lavfi -i testsrc=d=5 -codec:v rawvideo -pix_fmt rgb24  -y out.avi
[21:35] <saste> if you change -pix_fmt rgb24 with bgr24  it will work fine
[21:36] <saste> so it seems the demuxer cannot distinguish between bgr24 and rgb24
[21:37] <saste> with other formats it is even worse (e.g. rgb4 detected as PAL8)
[21:39] <michaelni> if you have / can find samples that are known to be correctly storing rgb4 & rgb24 then it should be easy to implement them
[21:40] <saste> michaelni, ok
[21:41] <saste> michaelni, can you explain why the codec_tag mechanism is not used/ is considered broken?

[22:09] <Daemon404> swr fate tests crash ffmpeg
[22:10] <nevcairiel> how many patches missing from git now?
[22:10] <Daemon404> the three i just sent, and im working with nicolas to figure out the 4th
[22:10] <Daemon404> then converter needs to be fixed
[22:10] <Daemon404> cause it trips an assert on ffprobe.c
[22:10] <nevcairiel> heh
[22:10] <Daemon404> and i need to figure out why this fate test crashes ffmpeg.exe
[22:11] <nevcairiel> maybe a similar asm issue as avr has :P
[22:11] <Daemon404> ;p
[22:12] <Daemon404> ill try and build with debug symbols
[22:12] <Daemon404> i dont know how to add it with cl.exe
[22:12] <Daemon404> off the top of my head
[22:13] <Daemon404> (what to add to cflags and ldflags)
[22:14] <nevcairiel> --enable-debug should be set to produce it
[22:14] <Daemon404> oic
[22:14] <Daemon404> works for msvc?
[22:14] <nevcairiel> i saw something in the flag filtering for it
[22:14] <Daemon404> vsynth1 and vsynth2 work with ffmpeg.exe
[22:14] Action: Daemon404 goes back to swr
[22:16] <nevcairiel> might need /debug in ldflags, not sure how it behaves whtn the objects have debug info and the linker is not instructed to keep it explicitly
[22:17] <nevcairiel> i'll try that soon enough either way
[22:17] Action: Daemon404 is doing it now
[22:17] <Daemon404> only 8 more years will configure finishes
[22:18] <nevcairiel> full fate run just took (only) 8 minutes, i wonder how much of that time was configure :p
[22:18] <Daemon404> lol
[22:18] <Daemon404> it takes longer than build for me
[22:18] <nevcairiel> about the same time here, 3 minutes each, 2 minutes for the fate run
[22:18] <nevcairiel> crazy
[22:19] <Daemon404> i dont see yout x64 instance
[22:19] <Daemon404> it isnt listed
[22:19] <nevcairiel> its way down with the other x64 instances
[22:19] <Daemon404> oh it is
[22:19] <Daemon404> yeah
[22:21] <Daemon404> oh. BBB just sent the 4th patch to libav's list
[22:23] <nevcairiel> anyone still running pre-XP deserves to be screwed anyway
[22:23] <nevcairiel> personally, i would include people running XP into that group, but i'll probably be chased by an angry mob
[22:23] <Daemon404> lol
[22:23] <Daemon404> i support whatever ms supports

[22:36] <nevcairiel> go nuts
[22:36] <Daemon404> lol
[22:37] <nevcairiel> i simply named it "ar" and put it into path so i dont need a --ar param
[22:37] <nevcairiel> should maybe figure out how to make configure aware of lib.exe
[22:38] <nevcairiel> although after poking configure and the makefiles for an hour or so today to try to figure out shared builds, my head still hurts
[22:39] <Daemon404> there we go
[22:39] <Daemon404> lib.exe is needed for debug builds
[22:39] <Daemon404> otherwise it wont link
[22:39] <nevcairiel> aha
[22:43] <Daemon404> and it works
[22:45] <nevcairiel> got some nice debug info?
[22:45] <Daemon404> indeed
[22:45] <Daemon404> but i need ot get it to michael...
[22:45] <Daemon404> and i have no clue how to export a report
[22:46] <nevcairiel> a nice way is to save a dmp file, but that only works if whoever you're sending it to also has msvc, so ... no :P
[22:46] <michaelni> saste, not sure what you mean by "not used", avi codectags are as they are in avi, its how the thing is designed
[22:46] <Daemon404> nevcairiel, yeah
[22:46] <nevcairiel> but those files are still nice and full of infos
[22:47] <Daemon404> interestingly
[22:47] <Daemon404> it crashes in af_pan.c
[22:47] <nevcairiel> asm?
[22:47] <Daemon404> no.
[22:47] <Daemon404> want a .dmp?

[23:15] <Daemon404> but thats only for logging callback
[23:15] <Daemon404> and shouldnt be an issue here
[23:20] <nevcairiel> the issuer there is odd
[23:20] <nevcairiel> the value of the "len" parameter is very close to the pointer of "arg0"
[23:20] <nevcairiel> somehow it got in there
