[12:56:25 CET] <durandal_1707> got from 0.3 to 129 real time speed
[13:10:55 CET] <durandal_1707> atomnuker: can i have imdct for 1536, 768, 384, 192 and 96 ?
[13:15:26 CET] <atomnuker> I did actually look into it this morning, and that one is nasty
[13:16:05 CET] <atomnuker> well, not really, its far far better than 15, but still to make one of those you need either 12 or 24 or 48
[13:16:55 CET] <atomnuker> I think for a generic fft capable of those and powers of two and multiples of 15 the kiss-fft approach is better
[13:17:29 CET] <atomnuker> and it would save on needing to prereindex
[13:18:30 CET] <atomnuker> one thing I'm wondering is if such an approach could match the speed for our transform
[13:24:56 CET] <nevcairiel> In another project i recently switched from KissFFT to PFFFT, which is considerably faster and has SIMD, and supports very variable sizes, although I have no clue how to make a IMDCT out of a FFT =p
[13:25:31 CET] <durandal_1707> does mpeg-h have specification somewhere?
[13:28:07 CET] <JEEB> yes, check ISO/IEC and chiarliglione's site for drafts
[13:28:29 CET] <nevcairiel> its mpeg, so probably not for free
[13:39:45 CET] <JEEB> depends. ISOBMFF and HEVC are free for example
[13:39:56 CET] <JEEB> (although then 14496-15 isn't free for some reason)
[13:40:05 CET] <JEEB> which is why the meeting document archives
[13:40:11 CET] <JEEB> and chiarliglione's site
[13:40:18 CET] <JEEB> are nice for draft DOC files :P
[14:01:16 CET] <kierank> nevcairiel: just move some values around iirc
[14:19:29 CET] <durandal_1707> cant open docx with libreoffice
[14:25:13 CET] <JEEB> huh, mine can (surprisingly OK)
[14:25:21 CET] <JEEB> although I guess depends on the exact document?
[14:25:41 CET] Action: JEEB is currently on 6.1.5.2
[14:26:05 CET] <durandal_1707> ISO-IEC_23008-3_(E)_(CD of 3DA).docx - whatever that is
[14:26:33 CET] <JEEB> will check when I have the time. if needed I can print out a PDF at home from MS Office
[14:57:17 CET] <tronifier> Hello everyone.
[15:02:30 CET] <tronifier> clear
[15:06:14 CET] <jdarnley> Dont shock the patient.  Hes still concious.
[15:28:40 CET] <durandal_1707> who gonnna REed ProRes and Blackmagic RAW ?
[15:31:11 CET] <gnafu> Elvis.
[16:41:02 CET] <cone-953> ffmpeg 03Paul B Mahol 07master:007c13e51e73: avfilter/af_anlmdn: add output mode option
[18:11:54 CET] <shivamgoyal> Hi, I have written a XV video file to flv converter ( It is also working on the provided "1.xv" and  "5.xv" files) as my qualification task for GSoC 2019. I just need some guide on how to combine the code with existing ffmpeg codebase.  
[20:23:27 CET] <durandal_1707> can i become ML maintainer so I can ban nicolas and carl? PLEASE!
[21:29:59 CET] <durandal_1707> should i post WIP ac4 patches to ML?
