[00:00] <Tjoppen> ubitux: where is it from?
[00:00] <ubitux> deringing in pp
[00:00] <ubitux> libpostproc/postprocess_template.c
[00:01] <ubitux> around L1350
[00:02] <Tjoppen> hm
[00:02] <Tjoppen> it's some kind of kernel for deringing?
[00:03] <ubitux> looks like some kind of weigthed histogram or something to me
[00:03] <Tjoppen> this feels worthy of posting somewhere
[00:03] <ubitux> but i really have no idea how that work
[00:04] <Tjoppen> it's ANDing the s[y] together
[00:04] <Tjoppen> ah, and shifts them back. hrmm
[00:04] <ubitux> http://24.media.tumblr.com/tumblr_mamw0rbkSE1qbsw6yo1_400.gif
[00:04] <ubitux> magic
[00:05] <ubitux> saste: so no problem with removing the auto clipping from gradfun options?
[00:05] <Tjoppen> ok, so the (t<<1) & (t>>1) bit basically checks for adjacent pixels which are brighter than average
[00:05] <Tjoppen> for each pixel
[00:08] <Tjoppen> let's see who the hell wrote that mess :)
[00:10] <Tjoppen> 2e212618 postproc/postprocess_template.c               (Michael Niedermayer  2001-10-26 00:35:41 +0000 1448)            t |= (~t)<<16;
[00:10] <Tjoppen> not big surprise
[00:30] <ubitux> we lost michael :(
[00:33] <kierank> cia got him
[00:33] <ubitux> :(
[00:37] <saste> ubitux: ok with removing the clipping to me
[00:37] <ubitux> ok, i'll push in a moment then
[00:37] <saste> s/to me/for me/
[00:49] <cbsrobot> Tjoppen: ping
[00:49] <cbsrobot> your mxf patch breaks fate
[00:51] <Tjoppen> oh noes
[00:53] <cone-798> ffmpeg.git 03Michael Niedermayer 07master:c4a32d92fee3: ffmpeg: Fix shortest with libx264
[00:55] <Tjoppen> it's late so I'll look at it tomorrow
[01:02] <ubitux> michaelni: btw, since you are working looking on libx264, there is a valgrind problem i wasn't able to figure out
[01:02] <ubitux> are you interested?
[01:03] <ubitux> ’ x4->out_pic.quality is sometimes undefined so it leads to uninitialized read in ffmpeg.c (for stats)
[01:03] <ubitux> i don't really understand why it's not init
[01:03] <michaelni> how to reproduce ?
[01:04] <ubitux> valgrind ./ffmpeg_g -f lavfi -i testsrc -frames:v 2 -c:v libx264 -f null -
[01:05] <ubitux> i tried something like http://pastie.org/5549927
[01:05] <ubitux> but i'm not sure to understand why it's needed, and i got another problem iirc
[01:57] <michaelni> ubitux, my valgrind here does not work with x264, later uses some instruction that valgrind cant handle
[02:00] <ubitux> mmh, no libx264 option to disable optim or sth?
[02:00] <ubitux> maybe a simpler profile could help
[02:02] <ubitux> this is what i have: http://pastie.org/private/kvdstjysewqb1bmnngq
[02:26] <michaelni> ubitux, here valgrind gives for this: vex amd64->IR: unhandled instruction bytes: 0x66 0xF 0x38 0x41 0xC0 0x66 0xF 0x7E
[02:27] <michaelni> valgrind-3.7.0
[02:31] <drv> 660F3841C0 is phminposuw xmm0,xmm0
[02:36] <ubitux> p`pwgen` xmm0,xmm0

[02:37] <ubitux> p`pwgen -N1` actually
[02:47] <drv> hehe, the newer SSE instructions do look a lot like line noise :)
[02:58] <iive> ph min pos uw, finds the minimus position in unsigned words? (just guessing from the op name)
[03:10] <ubitux> michaelni: did you try -cpuflags -sse4 or something?
[03:11] <ubitux> (not sure if that get transmitted to libx264 though)
[03:17] <durandal_1707> does anyone have als spec?
[03:17] <Compn> check mikes mirror page ?
[03:18] <durandal_1707> it is in doc and not full
[03:18] <durandal_1707> i want pdf one which is sold

[03:19] <Compn> durandal_1707 : hmm, maybe i can locate it
[03:20] <Compn> which one is als ?
[03:21] <Compn> MPEG-4 Audio Lossless Coding (ALS)
[03:21] <ubitux> i think it's defined in the 1.4k pages from the audio mpeg4 part
[03:21] <Paranoialmaniac> yes
[03:23] <cone-798> ffmpeg.git 03Clément BSsch 07master:de2022c5dd00: lavfi/gradfun: small align cosmetics.

[04:26] <ubitux> michaelni: why is copyAhead=9 for dering, while it seems to be reading up to 10 values?
[04:37] <michaelni> ubitux, its a long time ago since i wrote this code, but dering reads a 1 pixel border on all sides of a 8x8 block
[04:38] <michaelni> the copy ahead probably just counts the 1 ahead of the bllock
[04:38] <ubitux> mmh, ok
[04:38] <ubitux> thx
[07:15] <wm4> ubitux: hilariously outdated, linked from the ffmpeg documentation page: http://wiki.multimedia.cx/index.php?title=FFmpeg_filter_HOWTO
[07:16] <wm4> though I guess there are worse offenders

[12:36] <Matias^> anybody here ever tried to use -use_wallclock_as_timestamps ?
