[02:23] <darkfires> is there a way to force ffmpeg to this Stream #0.0: Video: mpeg4, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 25 fps, 25 tbr, 1200k tbn, 30 tbc? I'm having a problem with an IP camera, it's got a bug in the firmware and the manufact wont respond to my emails, basically the first time you connect the proper vol header is sent, any subsequent connect without a reboot the header is corrupt [02:23] <darkfires> i've been trying with various options but im getting no where [03:26] <Compn> darkfires : can you relay the stream so we can access it [03:26] <Compn> there is a program called socket2socket, part of desproxy project that can do it, if you cant figure it out in your router ... [03:27] <Compn> and whats ffmpeg say about it after the header is corrupt ? [03:27] <Compn> its possible to force it, depends how much data is coming [03:27] <Compn> and the format the camera streams [03:27] Action: Compn goes afk [03:53] <CIA-17> ffmpeg: 03Anton Khirnov 07master * rf5f5b154e7 10ffmpeg/doc/APIchanges: doc/APIchanges: fill in missing dates and hashes.

I need to know if there are any good sources where I can understand about the fundamentals behind video codecs? [12:45] <Compn> wikipedia has that stuff trupheenix [12:45] <av500> also the video from greg [12:45] <trupheenix> Compn, any good books i can read? or there are no books on this subject? [12:47] <av500> tried amazon? [12:47] <trupheenix> av500, no [12:47] <trupheenix> av500, what video from greg? [12:50] <av500> http://wiki.xiph.org/A_Digital_Media_Primer_For_Geeks/Episode_01 [13:11] <Compn> trupheenix : oh, you mean video coding and dct and stuff [13:11] <Compn> i thought you meant ... how codecs work, not the algorithms and such [13:11] <Compn> yeah there are books [13:11] <trupheenix> Compn, !!! yes!! :) finally! :) [13:11] <j-b> where is episode 2? [13:12] <Compn> trupheenix : http://codecs.multimedia.cx/?p=70 [13:12] <Compn> lists a couple good books [13:13] <Compn> as for the rest, i dunno, best ask someone else, maybe kostya :) [13:16] <trupheenix> Thanks Compn. I'm pretty bad at my calculus. Need to see these! :) [14:09] <kierank> oh he's gone [14:40] <funman> michaelni: you dont' want to use separate postproc repo because of fate? couldn't fate be changed to fetch postproc? [15:35] <Compn> cant git do like svn externals ? [15:36] <Compn> not that i care one way or the other [15:36] <JEEBsv> yes [15:36] <JEEBsv> git submodules [15:51] <michaelni> JEEBsv, submodules are very annoying [15:52] <av500> use repo [15:52] <michaelni> funman, ill just keep external and internal in sync [15:54] <funman> sounds like a plan [15:55] <michaelni> ive looked at submodules and subtree and a few other things but it all looked like it would be a bigger mess [15:55] <funman> in that case merging is free [15:59] <michaelni> Daemon404, ping [16:00] <michaelni> wth is this: Merge: 3a6e4e6 a792a83 8cf4ef5 59d8d9c 7876565 ??? [16:00] <michaelni> i mean yeah its a merge of 5 branches but [16:00] <michaelni> why is it there in libpostproc repo [16:03] <michaelni> also, whats "This file is part of FFmpeg/Libav." ?? [16:03] <michaelni> libpostproc was not developed in libav and isnt part of it either [16:03] <michaelni> its either part of FFmpeg or part of libpostproc [16:06] <michaelni> copyright (c) 2006 Michael Niedermayer <michaelni@gmx.at> [16:06] <michaelni> This file is part of Libav. [16:07] <Compn> its part of XXX or YYY , the line is only to provide where the file came from [16:07] <Compn> altho why it says libav when its from ffmpeg is another question [16:07] <Compn> similar things were done to files in mplayer that mplayer collected over the years [16:08] <Compn> i dont remember the reasoning for abandoning the original 'file is from' part, only so people dont copy over incorrect license headers i guess [16:08] <Daemon404> [10:07] <@Compn> altho why it says libav when its from ffmpeg is another question <-- it has stuff from both sides. [16:08] <Compn> definitely a question to ask dondiego [16:08] <Daemon404> :politics: [16:08] <michaelni> libav and 2006 ... [16:09] <Compn> Daemon404 : it should say @Copyright blah blah if that were the case [16:09] <Daemon404> it has code from both sides. [16:09] <Compn> the 'file is from' is not a copyright declaration [16:09] <Daemon404> what [16:09] <Daemon404> [10:00] < michaelni> wth is this: Merge: 3a6e4e6 a792a83 8cf4ef5 59d8d9c 7876565 <-- i wodnered this myself [16:09] <Daemon404> it seems to be a biproduct of filter-branch [16:10] <Daemon404> [10:03] < michaelni> libpostproc was not developed in libav and isnt part of it either <-- it has commits from them [16:10] <Compn> Daemon404 : i just mean, if libav has changed the file, whoever changed the file should put his copyright on there, assuming it was enough code to add copyright .. [16:10] <Daemon404> it is not a matter of copyright as far as im concerned [16:10] <Daemon404> it;s a matter of where it lived [16:10] <Daemon404> it lived in both ffmpeg and libav. [16:11] <Daemon404> and seriously, you gusy can take your politics and shove it. [16:11] <Daemon404> i will not involve myself in them. [16:11] <michaelni> <Daemon404> it has code from both sides. [16:11] <michaelni> then git blame isnt working [16:11] <Compn> i'm not trying to start a flame so i'll go away... [16:11] <Compn> michaelni : are you saying there are no changes from libav ? [16:11] <michaelni> Compn, not in x86_cpu.h [16:12] <michaelni> or blame -C -w is lying to me [16:12] <Daemon404> then change it [16:12] <Daemon404> i seriously do not give a shit about this libav/ffmpeg political bullshit anymore. [16:12] <Daemon404> do as you wish. [16:13] <michaelni> Daemon404, what about the 5 head merge ? [16:13] <Compn> Daemon404 : you sound upset :( [16:13] <Daemon404> on the technical side there, i dont know what to do to fix that per se, michaelni [16:14] <Daemon404> do you want my git filter branch commandss? [16:14] <michaelni> i could just clone ffmpeg and throw all bit libpostproc out and it wont have such monsters [16:14] <Daemon404> perhaps you could spot it [16:14] <Daemon404> Compn, i merely no longer wish to ever hear any of this politics crap again. too many things i do get plagued with it. [16:14] <Daemon404> i prefer ignorant bliss now. [16:15] <michaelni> if libpostproc is a true clone i also could do a true git merge to keep them in sync ... [16:17] <Daemon404> it's not a clone [16:17] <Daemon404> it's a filtered branch. [16:17] <michaelni> i know [16:17] <Daemon404> my intention was to filter out the noise of all the otehr unrelated commits [16:17] <michaelni> i understand that [16:17] <michaelni> i dont understand why it has 5 headed monsters in there [16:19] <Daemon404> i think it may be teh 2nd command i ran... maybe [16:19] <Daemon404> sec [16:19] <Daemon404> (it has to do with the merges you did from libav) [16:20] <Daemon404> http://pastebin.com/raw.php?i=gr9SUP3M [16:20] <Daemon404> ^ what i used [16:20] <Daemon404> just a ... bit ... ugly [16:22] <michaelni> whats your oppinon on using a true clone, its kinda ... less work ? [16:22] <Daemon404> far less work [16:22] <Daemon404> less nice lookign history wise [16:23] <Daemon404> it's up to you. [16:23] <michaelni> if its up to me, ill pick a clone [16:23] <Daemon404> ok. [16:42] <bgmarete> Hello. I am looking for interlaced video sequences to test the yadif filter. Any down-loadable ones from the web? With varying field parity? Or how can I use FFmpeg to create such? Thanks! [16:46] <cbsrobot> bgmarete: what is varying field parity ? [16:47] <bgmarete> cbsrobot: I mean I would like some samples to be tff and others bff. [16:47] <bgmarete> (If possible) [16:48] <michaelni> i remember generating such (half framerate) sequences with mencoder long ago from progessive input [16:48] <michaelni> i dont remember how exactly i did it though ...
