[00:07] <jamrial> ubitux: it's from http://research.microsoft.com/en-us/um/people/kopf/pixelart/supplementary/multi_comparison.html the filter they call "ours"
[00:08] <ubitux> oh i thought it was xbr
[00:08] <ubitux> that's the MS one, ok
[00:11] <ubitux> http://b.pkh.me/yoshi-16br.png this is xbr x16 (2 successive 4br, assuming that was the process they used)
[00:12] <ubitux> and my eyes hurt now
[00:13] <ubitux> http://b.pkh.me/yoshi-hq16.png this is what i get with 2 sucessive hq4x
[00:14] <ubitux> it's somehow different from their results
[00:14] <ubitux> http://research.microsoft.com/en-us/um/people/kopf/pixelart/supplementary/results_hq4x/smw2_yoshi_01_hq4x_16x.png
[00:14] <ubitux> our hqx=4,hqx=4 looks better :p

[18:19] <kurosu> jamrial: http://ffmpeg.org/pipermail/ffmpeg-devel/2013-May/143520.html
[18:19] <kurosu> when I did that, the benchmark were not particularly enticing
[18:22] <jamrial> save for order 4 it was faster when i benched. i didn't consider the memset overhead but using AVZERO should deal with that
[18:23] <kurosu> yeah, I was surprised when I saw the results, but didn't want to bother
[18:24] <kurosu> *saw my results (at the time)
[18:25] <wm4> nevermind that you can't seek correctly in tak (AFAIK), which completely ruins user experience
[18:25] <wm4> or maybe it was some other format
[18:31] <cone-325> ffmpeg.git 03Paul B Mahol 07master:586ba24ff294: avcodec/exr: fix memset first arg in reverse_lut()
[19:43] <cone-325> ffmpeg.git 03Michael Niedermayer 07master:40adcf576f7d: avformat/oggdec: Check for ost allocation failure
[19:47] <jamrial> kurosu: that patch of yours could be applied. no need to bother adding unaligned AV_ZERO macros for this
[19:48] <jamrial> what did you use to bench back then? the fate sample?
[19:48] <jamrial> because that's probably too short to get proper numbers
[19:49] <jamrial> i encoded a 22 minutes long song using the encoder the author distributes
[19:56] <kurosu> jamrial, I don't quite remember
[19:57] <kurosu> up to you which one should be applied (eg not sure mine still applies)
[19:58] <kurosu> hum, actually I'm sure it wasn't the fate sample, but not sure it was the ones on samples.mphq
[19:59] <kurosu> on a related subject, do you have any idea how feasible is porting to yasm ?
[20:00] <jamrial> porting what?
[20:00] <kurosu> the remaining mlp dsp function
[20:01] <kurosu> you know, that duff device, where jump labels are stored into regs
[20:01] <jamrial> ah, filter_channel
[20:01] <kurosu> yeah
[20:02] <kurosu> I had looked at it like 3 years ago wondering if sometimes shortcut could be taken (like int32_t*int32_t->int32_t)
[20:02] <kurosu> also not sure if doing 2 samples (2 channels) per xmm would be possible
[20:03] <jamrial> something like we're doing with flac?
[20:03] <kurosu> haven't looked at it
[20:03] <kurosu> it probably requires changing a lot of buffers anyway
[20:04] <kurosu> but well, that looks so useless, seeing how mlp is not very used afaik
[20:04] <kurosu> wasn't it hddvd only for instance?
[20:04] <jamrial> no, it's used on blu-ray as well
[20:04] <kurosu> ok
[20:05] <jamrial> it's used on dvd-audio, probably also blu-ray audio, and for lossless tracks on blu ray movies (with ac3 as fallback)
[20:10] <kurosu> I thought dtshd-ma was more frequent
[20:10] <nevcairiel> it is, its still present however
[20:15] <kurosu> https://github.com/kurosu/ffmpeg/commits/mlpdsp <- useless stuff I had worked on
[20:15] <kurosu> refreshed that today, I think now it slows things down...
[20:16] <kurosu> the intent was to cleanup a bit buffers as a start point
