[02:41] <michaelni> Compn, before your commit the censorship logo was over the heading of the news entry now its not anymore
[02:42] <Compn> michaelni : yeah, should be fixed
[02:42] <pasteeater> Compn: you need to add a space between " and /.
[02:43] <pasteeater> and the img also needs an alt tag
[02:43] <pasteeater> then you can probably remove the <p> and </p<
[02:43] <pasteeater> >
[02:43] <Compn> i'll let you :)
[02:44] Action: Compn brain fried
[02:45] <pasteeater> i still haven't given michaelni my public ssh key
[02:45] <pasteeater> been out of town too much lately
[02:45] <michaelni> Compn, why did you remove the style="position: absolute; z-index:5000" ?
[02:45] <michaelni> was there a problem with it ?
[02:46] <michaelni> it nicely displayed over the text in firefox as it was ...
[02:51] <michaelni> can someone test my original version in some other browser than firefox ?
[02:53] <pasteeater> is it supposed to be over the news entry title?
[02:54] <Compn> i didnt like it over the news entry title
[02:54] <Compn> i just made it a normal image link
[02:54] <Compn> maybe its just me 
[02:54] <Compn> i thought you wanted to post it as an entry, not censoring the news page :P
[02:54] <gnafu> I thought it was supposed to be accross the website's actual logo :-P
[02:55] <Compn> gnafu : it was supposed to be on the 16th, but i didnt see it til the 18th :P
[02:55] <Compn> so we are repositioning it 
[02:55] <michaelni> i liked it over the news entry :(
[02:55] <Compn> well feel free to revert then
[02:55] <michaelni> over the logo looks odd half a week after the thing
[02:55] Action: Compn using opera
[02:56] <michaelni> did it work in opera?
[02:56] <Compn> yes
[02:56] <michaelni> over the heading or text ?
[02:56] <Compn> the sopa bill is still awaiting a vote, isnt it ?
[02:56] <michaelni> iam no politican, no idea
[02:56] <Compn> i mean, just because that website says somethings over.... i didnt get the impression that the fight was over 
[02:56] <Compn> in fact, the meeting that occured on the 16th was really bad
[02:57] <michaelni> the fight is surely never over, these things will be retried and retried ...
[02:57] <Compn> but i mean... sopa isnt dead yet, it just had a meeting on the 16th
[02:59] <michaelni> Compn, ok if i try to put it back over the heading ?
[02:59] <Compn> sure, put it where you want it :)
[02:59] <Compn> i just thought you did a bad copy paste :P
[02:59] <Compn> as evidenced by your removing the <a> tag on template_head2
[02:59] <Compn> er , not replacing the <a> tag that is
[03:00] <michaelni> iam sloppy & scatterbrained :)
[03:00] <Compn> i have no objections to where it goes , i fixed it without asking :)
[03:01] <michaelni> well if theres some way i could improve it iam surely interrested in doing that
[03:01] <michaelni> but IMHO putting it over the heading is a eye catcher
[03:02] <michaelni> so more likely people would look & click & support

[03:04] <ubitux> Compn: you might want to add a alt="censorship..." to the img so it is a bit more valid
[03:04] <ubitux> there is also a <pre> issue that might be fixed by taking out the nested <pre> in the <p>
[03:05] <ubitux> anyway, 'night ppl
[03:08] <Compn> michaelni : ubitux and pasteeater want you to add an alt tag too :P
[03:09] <michaelni> ill add the alt tag
[03:10] <michaelni> Compn, what exactly should i put in it ?
[03:11] <Compn> stop censorship logo
[03:11] <Compn> alt tag is what pops up when you put your mouse cursor over an image
[03:12] <Compn> its used for screen readers so blind people get an audio description of an image
[03:13] <michaelni> added
[03:14] <Compn> ffmpeg logo alt tag should be something like 'ffmpeg logo containing zigzag motion search. created by herve ...'
[03:14] <michaelni> "..." ?
[03:15] <Compn> ... being herve's last name i've forgotten
[03:15] <michaelni> "ffmpeg logo containing zigzag motion search. created by herve being herve's last name i've forgotten" ?
[03:15] <pasteeater> Flores
[03:16] <Compn> heh
[03:17] <michaelni> what is "zigzag motion search" ?
[03:17] <Compn> FFmpeg logo displaying the zigzag motion search algorithm. logo is copyright Hervé Flores.
[03:17] <Compn> isnt that what the zigzag is ?
[03:17] <Compn> i dont actually remember what it is
[03:17] <michaelni> idct scantable
[03:18] <Compn> ah
[03:18] <michaelni> btw, isnt "ffmpeg logo" enough ?
[03:18] <Compn> well would a blind person know what it looks like?
[03:18] <Compn> of course, idct scantable is advanced idea too :D
[03:19] Action: Compn runs afk
[03:19] <Compn> bbl
[03:19] <ohsix> how many blind people are interested in this information heh
[03:20] <michaelni> i dont know, but id imagine they would be more interrested in the content of the page, and the links to other pages
[03:21] <michaelni> ill leave the alt logo text bikeshed to others, iam fine with anything compn likes
[03:28] <pasteeater> "FFmpeg" is fine with me
[03:29] <Compn> you guys are no fun, bikesheds are important.
[03:31] <pasteeater> give me a good mandelbrot example instead
[03:31] <michaelni> pasteeater, the defaults ?
[03:32] <pasteeater> "ffplay -f lavfi mandelbrot"?
[03:32] <pasteeater> that's all i've tried

[14:25] <michaelni> it works with that here with git master

[14:34] <michaelni> are you using git master of ffmpeg?

[14:34] <michaelni> and which libaacplus version ?
[14:35] <kkk> ehm the last
[14:35] <kkk> i think
[14:35] <michaelni> ok
[14:35] <michaelni> maybe its a windows specific bug, i dunno
[14:35] <kkk> windows?
[14:35] <kkk> No, i'm using it under linux
[14:37] <michaelni> kkk you are using a windows build from zeranoe under linux ? ;)
[14:38] <ubitux> zeranoe seems to provide source snapshots too
[14:38] <ubitux> but maybe they are patched?
[14:38] <kkk> windows builds unter linux ?
[14:39] <kkk> No? How i should ? :D
[14:39] <kkk> I'll compile from the source
[14:39] <ubitux> ffmpeg.org also provides snapshots, why are you using zeranoe ones?
[14:42] <michaelni> kkk, also make sure you have matching headers & binaries from libaacplus
[14:42] <kkk> michaelni
[14:42] <kkk> i'm using the same sources

[17:23] Action: Daemon404 pokes nevcairiel again
[17:24] <nevcairiel> hm?
[17:25] <Daemon404> nevcairiel, im not sure if this is an ffdshow bug or a lav splitter bug
[17:25] <Daemon404> but ffdshow + lav splitter refuse to connect for COOK audio
[17:25] <Daemon404> (when splitting rmvb)
[17:25] <Daemon404> lav audio connects fine

[17:27] <nevcairiel> lav splitter doesnt output the full RealAudio header, and i suppose ffdshow expects that
[17:27] <Daemon404> that might be why
[17:28] <nevcairiel> ffmpeg doesnt offer the full header, and i didnt really bother to try to re-create it
[17:29] <Daemon404> i see
[17:29] <Daemon404> ffdshow connects when cook audio is in mkv, and haali is splitting it
[17:29] <Daemon404> so you can check what it does?
[17:30] <nevcairiel> mkv could potentially work with lav splitter as well
[17:30] <nevcairiel> its only the rm demuxer in avformat that doesn't export the full RealAudio header in extradata
[17:30] <Daemon404> i see
[17:31] <Daemon404> cause i tried lav splitter, only cause the internal rm splitter in mpc-hc is busted as hell
[17:32] <nevcairiel> I wouldnt know, i really dont watch any rm
[17:32] <Daemon404> neither do i
[17:32] <Daemon404> but my SO does
[17:32] <Daemon404> thus -> my problem
[17:36] <kkk> michaelni you we're right, libaacplus is not working at all
[17:36] <kkk> maybe because of libvo_aacenc. I'll try it later
[17:43] <Daemon404> interesting nick

[21:46] <NoorulIslaam> im encoding video on android using ffmpeg+x264
[21:46] <NoorulIslaam> but even on the fastest settings for x264, i cant seem to get more than 6 or 7 FPS
[21:46] <NoorulIslaam> im recording in realtime from the camera
[21:47] <NoorulIslaam> the camera frames are processed by an opengl renderer
[21:47] <NoorulIslaam> and i do glReadPixels in RGB565 format to get the video frames
[21:47] <NoorulIslaam> without video encoding, the rendering is as fast as the camera can supply frames
[21:47] <NoorulIslaam> any ideas on how to make the process go faster?
[21:48] <NoorulIslaam> i considered storing the raw frames and encoding them after the user presses stop recording
[21:48] <NoorulIslaam> but at 640x480, RGB565, 24 FPS, for 60 secs... that right there is more than 800 MB of space
[21:48] <iive> NoorulIslaam: can the camera capture in yuv mode?
[21:49] <NoorulIslaam> of course i am using YUV mode
[21:49] <NoorulIslaam> but once renderered to the screen it becomes RGB565
[21:49] <NoorulIslaam> then i read back the pixels using glReadPixels
[21:49] <iive> i don't understand what are you doing?
[21:49] <NoorulIslaam> before passing the frame onto the x264 encoder, i use sws_scale to convert it to YUV420P
[21:50] <NoorulIslaam> sorry, let me explain step by step:
[21:50] <NoorulIslaam> 1 - camera supplies frame in NV21 format (a yuv format)
[21:50] <NoorulIslaam> 2 - opengl renderer runs some effects on the frame, and renders to framebuffer in RGB565 format
[21:51] <NoorulIslaam> 3 - glReadPixels is called to readback the rendered frame in RGB565 format
[21:51] <NoorulIslaam> 4 - sws_scale called to convert RGB565 frame to YUV420P
[21:51] <NoorulIslaam> 5 - YUV420P frame encoded via ffmpeg+x264 and written to mp4 file
[21:52] <NoorulIslaam> thats what im doing
[21:52] <iive> why don't you store the video directly from the camera?
[21:52] <NoorulIslaam> because i need to apply effects on it
[21:52] <iive> what kind of effects?
[21:52] <pasteeater> what are your x264 settings?
[21:52] <NoorulIslaam> anything from warping the image, to sepia tinting, to outline detection, etc etc
[21:53] <iive> are you doing something like simulated reality?
[21:53] <NoorulIslaam> i dont know if you would call it simulated reality
[21:53] <iive> is the opengl done by gpu unit?
[21:53] <NoorulIslaam> i call it realtime effects
[21:53] <NoorulIslaam> yes opengl runs on the GPU
[21:53] <NoorulIslaam> if i turn off video recording, im doing only steps 1 & 2
[21:53] <NoorulIslaam> then i get up to 30 FPS or however fast the camera can deliver frames
[21:53] <iive> NoorulIslaam: virtual reality overlayed over real footage in real time.
[21:54] <NoorulIslaam> iive no thats not what im doing
[21:54] <iive> aka, adding 3d objects that are not present in the reality.
[21:54] <NoorulIslaam> no
[21:54] <NoorulIslaam> im taking the frame from the camera, running a opengl vertex/fragment shader program on it, and the output of that is shown on the screen
[21:55] <NoorulIslaam> to record it to video, i have to read back from the screen and encode
[21:56] <iive> can you benchmark the functions that take most time?
[21:56] <NoorulIslaam> pasteeater: im doing a lot of experimenting, trying to get it to ultrafast. i saw a marginal improvement from 4 FPS to 6~7 FPS, but thats the most i seem to be getting
[21:56] <iive> something like `perf top`
[21:56] <NoorulIslaam> pasteeater: which settings would you like to know about? there are a lot
[21:56] <iive> how much do you get if you send the raw frames to /dev/null.
[21:56] <iive> aka, what framerate.
[21:57] <NoorulIslaam> okay, let me see
[21:57] <NoorulIslaam> what i will do is go up to the glReadPixels call
[21:57] <NoorulIslaam> but not send the frame to the encoder at all
[21:57] <NoorulIslaam> give me 1 min
[22:00] <NoorulIslaam> okay, i was getting a much smoother FPS that way
[22:00] <NoorulIslaam> doing steps 1 to 3, but not steps 4 & 5
[22:00] <NoorulIslaam> dont know exactly what FPS it was since no frames were written to file
[22:01] <NoorulIslaam> let me add step 4 and see how much it slows down
[22:04] <michaelni> If you would do the filtering to the yuv then you would not have to read back the rgb and rgb->yuv
[22:05] <NoorulIslaam> with step 4 its a little more slower, it looks to me around 15 FPS but not sure because i dont have any FPS measuring code in there right now
[22:06] <NoorulIslaam> michaelni thats true but part of the shaders rely on RGB data
[22:06] <NoorulIslaam> so i cant change that part
[22:06] <NoorulIslaam> on the iphone 4 i can do this at about 20 to 25 FPS
[22:07] <NoorulIslaam> on the iphone 4s at the full framerate of the camera
[22:07] <NoorulIslaam> right now im testing on the galaxy note
[22:07] <NoorulIslaam> the resolution is 320x512
[22:07] <NoorulIslaam> on the iphone its 320x480
[22:08] <NoorulIslaam> of course on the iphone i use hardware accelerated encoding
[22:08] <NoorulIslaam> dont have access to that on android
[22:09] <NoorulIslaam> let me try now just encoding the frames but not writing them to the mp4 file...
[22:09] <michaelni> you can probably do some NEON optims here and there that might help a bit (and would be very welcome if you submited them to ffmpeg-dev)
[22:11] <NoorulIslaam> hmm yeah, there were some NEON optims added a few days ago i think
[22:11] <NoorulIslaam> i should update my ffmpeg source tree and recompile and see if they make a difference
[22:22] <NoorulIslaam> hmm okay so now im doing everything except av_interleaved_write_frame. framerate has dropped significantly
[22:22] <NoorulIslaam> but is noticeably faster than if im also writing frames to disk
