[00:33:23 CEST] <atomnuker> durandal_1707: yeah, I am
[00:34:14 CEST] <atomnuker> laptop broke down just as soon as I got it working so I haven't been able to make comparisons yet

[09:12:08 CEST] <saste_> I dislike the way the GSoC notice is shown on the website
[09:17:28 CEST] <fritsch> saste_: impressive tasks
[11:36:27 CEST] <saste_> really, are we going to translate the wiki to chinese? ^^
[11:46:45 CEST] <wm4> PHP? wtf
[12:18:05 CEST] <blez> hello
[12:18:19 CEST] <blez> I get "Unknown Error" using ffmpeg, how can I see what's the actual error?
[12:36:24 CEST] <atomnuker> Who wrote this stuff? It's wrong
[12:36:41 CEST] <wm4> what stuff
[12:36:43 CEST] <wm4> ffmpeg?
[12:36:50 CEST] <atomnuker> TNS worked pretty good for low bitrates up until Claudio's RC push broke it
[12:37:09 CEST] <atomnuker> (nobody say anything about that, it'll probably delay him another week)
[12:37:51 CEST] <atomnuker> whatever, I can't be bothered to care
[12:52:50 CEST] <iive> atomnuker: i think you should tell him.
[13:05:39 CEST] <durandal_170> atomnuker: can you fix it?
[13:06:39 CEST] <durandal_170> btw, you have working machine?
[13:28:13 CEST] <superware> I'm playing a live h264 over udp stream, but sometimes (network glitches etc) the stream hangs indefinitely. Restarting ffmpeg continues playback. Since it's very hard to reproduce, I've complied a very messed up stream which reproduces the issue, please see log http://pastebin.com/QuA5nCvQ up to line 229 where is some video, but after that - nothing.

[13:51:19 CEST] <superware> kierank: thanks, tried that, same...
[13:51:36 CEST] <kierank> open it in gdb and see where it blocks
[13:52:00 CEST] <kierank> I used to get these issues a lot
[13:52:35 CEST] <nevcairiel> i think his definition of hang is different, ffmpeg seems to still function, it just doesnt output frames anymore
[13:52:47 CEST] <superware> I don't think the code blocks, no video frame is playing after "the event", you can see the log keeps going...
[13:52:52 CEST] <kierank> ah
[13:52:58 CEST] <kierank> different bug to mine perhaps
[13:53:09 CEST] <superware> it's as if a specific packet/frame causes FFmpeg to enter a certain state from which it cannot recover
[13:53:13 CEST] <cone-619> ffmpeg 03Anton Khirnov 07master:ae25413daf42: lavfi: do not exclude hwaccel formats from ff_all_formats()

[13:54:41 CEST] <superware> the relevant lines from the log: reference count 2 overflow; reference picture missing during reorder; reference count overflow; decode_slice_header error; mmco: unref short failure; number of reference frames (0+2) exceeds max (1; probably corr
[13:54:41 CEST] <superware> upt input), discarding one; ...
[13:54:48 CEST] <kierank> that's just packet loss errors
[13:55:18 CEST] <superware> but it only happens when the issue occurs
[13:56:20 CEST] <kierank> anyway run in gdb and get a trace for all the threads where it hangs imo
[13:56:21 CEST] <superware> before that the video is very choppy (to non-existent) but none of those are reported
[13:56:25 CEST] <kierank> and open a ticket
[13:57:42 CEST] <superware> I don't think I have sufficient knowledge to debug ffmpeg h264
[13:57:46 CEST] <DHE> superdump: does 4 minutes, 20 seconds sound like the time before the stream shuts down? or is it more erratic?
[13:58:28 CEST] <DHE> (this assumes you're using multicast)
[13:59:09 CEST] <superware> superdump is here, but not me :)
[13:59:34 CEST] <superware> it happens after 1 minute and 38 seconds.
[14:01:41 CEST] <superware> I couldn't reproduce in normal operation, so I recorded the network pcap and discarded half of the packets.
[14:02:26 CEST] <DHE> oops
[14:03:24 CEST] <superware> now I have a file which I'm playing via PlayCap, ffplay starts playing some very messed up frames, but always stops outputting frames at the same time. restarting ffplay continues with the bad video.
[14:04:21 CEST] <DHE> so, half of 4:20....
[14:04:31 CEST] <superware> naa :)
[14:04:42 CEST] <DHE> ah, not quite...
[14:04:52 CEST] <DHE> sorry it's still early
[14:06:06 CEST] <superware> do you know of someone that has h264 experience?
[14:06:31 CEST] <DHE> me?
[14:07:10 CEST] <durandal_170> superware: could you upload file you give to ffplay?

[14:07:56 CEST] <durandal_170> does it happens with -threads 1?
[14:08:07 CEST] <DHE> it sounds to me like you've got a multicast stream that's possible encrypted, and missing an IGMP querier

[14:35:56 CEST] <saste_> who's the website maintainer?
[14:36:50 CEST] <saste_> there is this annoying margin-top: 180px attribute for h4 elements, how can I fix it?
[14:37:33 CEST] <wm4> there is a name I've never seen before in MAINTAINERS for the website
[14:38:31 CEST] <nevcairiel> isnt ubitux to blame for the recent redesign
[14:38:35 CEST] <nevcairiel> or do i mis-remember
[14:39:13 CEST] <ubitux> BBB: i'm sorry i won't have time
[14:39:17 CEST] <ubitux> wm4: api, not abi (subtitles)
[14:39:20 CEST] <BBB> oh youre still alive!
[14:39:23 CEST] <BBB> no problem
[14:39:24 CEST] <ubitux> nevcairiel: not really
[14:39:24 CEST] <Compn> the html of the website is in ffmpeg-web repo
[14:39:31 CEST] <ubitux> nevcairiel: db0 is the author
[14:39:41 CEST] <Compn> saste_ : i can commit to ffmpeg-web repo if you have a patch or just tell me what to edit
[14:40:12 CEST] <ubitux> grep website MAINTAINERS
[14:40:16 CEST] <saste_> Compn, I know where the ffmpeg web repository is
[14:40:32 CEST] <saste_> I wanted to ask, is she on IRC?
[14:41:12 CEST] <ubitux> she was, seems she hasn't been for a while
[14:41:20 CEST] <superware> durandal_170: sure, but I first want to verify it's a real issue, can you please try to reproduce?
[14:41:53 CEST] <saste_> there is something about the h4 attribute which is not immediately obvious, I can't grep for top-margin on the local repo
[14:43:51 CEST] <ubitux> BBB: yeah, surviving :)
[14:44:05 CEST] <BBB> awh :(
[14:44:25 CEST] <ubitux> (joking, i'm fine, just heavy load on various aspects)
[14:48:21 CEST] <superware> durandal_170?
[14:51:53 CEST] <superware> are there several different h264 decoders in ffmpeg?
[14:53:22 CEST] <wm4> there's only one, although there are several other wrappers for hw decoding APIs which decode h264
[14:54:20 CEST] <durandal_170> superware: I can't apt-get deps for playcap
[14:55:29 CEST] <superware> durandal_170: are you on Windows?
[15:08:45 CEST] <BBB> does anyone remember if theres an instruction on x86 (sse2 or so) to move just the higher half of a xmm register from one reg to another, but leave the lower half untouched?
[15:09:21 CEST] <BBB> (or move lower half and leave higher bits untouched)
[15:10:04 CEST] <BBB> the best I can think of is shufps but Im wondering if theres something better
[15:10:09 CEST] <nevcairiel> there is movhlps which moves the high-quadword from origin to the low-quadword of dest, without touching dests high-quadword, but i guess thats not quite what you need
[15:11:22 CEST] <nevcairiel> (and the reverse also exists)
[15:11:50 CEST] <BBB> right, thats low to high, I need high to high or low to low
[15:12:02 CEST] <BBB> shuffling is such a pain on x86 sometimes
[15:12:11 CEST] <BBB> too many instructions that do just a small subset of the general thing
[15:12:12 CEST] <nevcairiel> movhps can load the high quad from memory
[15:12:28 CEST] <nevcairiel> still no good eh?
[15:12:39 CEST] <BBB> hehehe right
[15:12:42 CEST] <BBB> I want movhps from reg to reg
[15:13:01 CEST] <durandal_170> superware: no, ubuntu
[15:13:05 CEST] <BBB> punpcklqdq is sort of like movlhps, in fact
[15:13:25 CEST] <BBB> but still not what I want

[15:45:32 CEST] <nevcairiel> BBB: i'll give it a look, but i cant promise much
[15:46:12 CEST] <BBB> nevcairiel: well, more generally, Im looking for someone tor review anything assembly at all
[15:46:22 CEST] <BBB> Ill have a few more coming up and nobodys reviewing, which kind of sucks
[15:47:05 CEST] <durandal_170> I just commit what nobody reviews
[15:51:58 CEST] <saste_> ubitux, are you optimizing testsrc or what?
[15:52:31 CEST] <ubitux> saste_: no, just wondering about the inconsistency between -t and -to
[15:52:42 CEST] <superware> is cehoyos here?
[15:52:50 CEST] <Daemon404> not usually
[15:53:08 CEST] <superware> ok
[16:29:50 CEST] <nevcairiel> getting rid of the convergence_duration hackery from my own code sure made my feel good
[16:29:56 CEST] <nevcairiel> s/my/me/
[16:33:45 CEST] <wm4> oh it's already in?
[16:34:13 CEST] <nevcairiel> an hour ago or so
[16:47:32 CEST] <BBB> I never understood why convergence_duration was introduced
[16:47:50 CEST] <nevcairiel> i think it was introduced for something else entirely
[16:48:00 CEST] <nevcairiel> it was then abused as a 64-bit duration field for subtitles
[16:48:03 CEST] <BBB> it seemed like somebody mistook a doxy comment for abi
[16:48:23 CEST] <BBB> hm, ok
[16:48:34 CEST] <nevcairiel> the comment still states its original concept
[16:48:40 CEST] <nevcairiel> or well used to until it was removed
[16:48:54 CEST] <Paranoialmaniac> i though it is used for gradual decoder refresh but...
[16:49:06 CEST] <nevcairiel> thats what it kinda was for
[16:49:18 CEST] <nevcairiel> time until the stream "converges", ie. when the refresh is done
[16:49:25 CEST] <nevcairiel> but it was never used for that
[17:24:37 CEST] <Gramner> BBB: for merging parts of registers; shufps with SSE, pblendw/blendps with SSE4.1, vpblendd with AVX2
[17:24:49 CEST] <BBB> ah, blend
[17:24:54 CEST] <BBB> ok, this is sse2 targetted, so shufps it is
[17:24:56 CEST] <BBB> ty
[17:25:20 CEST] <Gramner> in AVX-512 you can use an opmask blend with every instruction as well
[17:25:52 CEST] <durandal_1707> BBB: I want to write simd for maskedmerge filter
[17:26:54 CEST] <BBB> Gramner: uh ok that sounds a little overkill
[17:26:58 CEST] <BBB> typically intel I guess
[17:27:13 CEST] <BBB> durandal_1707: algo desc in C? and did you dspize the function?
[17:27:32 CEST] <BBB> (i.e. put it in a blaDSPContext in its own file with a nice header etc., and write a checkasm test, etc.)
[17:28:09 CEST] <durandal_1707> not yet
[17:28:56 CEST] <BBB> px1*weight+px2*(1-weight)?
[17:29:00 CEST] <BBB> (in fixed point)
[17:29:07 CEST] <Gramner> I'd say it's typical intel to invent this completely new backwards-incompatible future-proof instruction encoding called VEX (AVX), just to replace it again a few years later with EVEX. as a matter of fact, they had probably dropped VEX internally before hardware using it was even released to the general public
[18:41:43 CEST] <nevcairiel> so much for future proof =p
[18:53:34 CEST] <wm4> is anyone against applying that videotoolbox patch from Stefano Pigozzi?
[18:59:52 CEST] <TheRyuu> https://sourceware.org/bugzilla/show_bug.cgi?id=19011 <---do my eyes decieve me, sanity from gnu?
[19:01:46 CEST] <Gramner> TheRyuu: nice
[19:03:18 CEST] <JEEB> wow
[19:03:44 CEST] <TheRyuu> he's gonna be sad when it's a patch series though (if I do it)
[19:05:37 CEST] <cone-619> ffmpeg 03Michael Niedermayer 07master:ed18c49f5ff8: fate: Add basic license header check
[19:07:41 CEST] <jamrial> ^ i'd say tools/patcheck is the proper way to check this and not fate, but it wouldn't work for libav merges which is the source of the wrong headers, so guess it's ok
[19:10:41 CEST] <wm4> fate now tests source code too!
[19:11:36 CEST] <wm4> (I think someone wants to force someone else to change the project name on merges?)
[19:14:37 CEST] <durandal_1707> thats ok
[19:16:42 CEST] <durandal_1707> ubitux: is it ok to have assumefps?
[19:24:02 CEST] <DHE> there, hopefully that'll be the last revision of the a53 CC patch

[20:09:35 CEST] <ubitux> durandal_1707: what is it?
[20:13:02 CEST] <durandal_1707> changes fps and pts without dropping or adding frames
[20:25:55 CEST] <ubitux> durandal_1707: what would be the difference with setpts?
[20:26:39 CEST] <durandal_1707> setpts changes framerate?
[20:27:12 CEST] <ubitux> no because of the expression i guess
[20:28:01 CEST] <ubitux> what field are we talking about?
[20:28:07 CEST] <ubitux> we have a link->framerate or sth?
[20:29:38 CEST] <durandal_1707> frame_rate
[20:30:02 CEST] <ubitux> just add a setframerate filter maybe
[20:30:11 CEST] <ubitux> that just changes this field
[20:30:30 CEST] <ubitux> but well, then adding a setpts filter would be annoying
[20:30:43 CEST] <ubitux> yeah well, dunno, no opinion
[20:32:26 CEST] <durandal_1707> setfps is shorter
[20:48:00 CEST] <wm4> why are the old vdpau hwaccels (h264_vdpau etc.) still not gone?
[20:53:58 CEST] <durandal_1707> nobody removed them
[20:59:02 CEST] <cone-619> ffmpeg 03Paul B Mahol 07master:a01914924969: avfilter/vf_atadenoise: do not use uninitialized data
[21:13:22 CEST] <iive> somebody said that libav have delayed ff_api_vdpau once again, so we are doing that too.
[21:13:56 CEST] <nevcairiel> welcome to 4 weeks ago
[21:14:41 CEST] <nevcairiel> the deprecation just isnt that old yet
[21:17:13 CEST] <wm4> Libav have removed these codecs ages ago
[21:17:23 CEST] <wm4> what they didn't remove are some API symbols
[21:17:25 CEST] <durandal_1707> JEEB: tried zscale?
[21:17:38 CEST] <BBB> wm4: I believe the deprecation works functionally, so if you dont like that feature, just use -DFF_API_blabla=0 as extra-cflags=..; configure arg
[21:17:41 CEST] <wm4> (like CODEC_CAP_HWACCEL_VDPAU)
[21:18:11 CEST] <JEEB> durandal_1707: I did before, I should test a newer version
[21:18:11 CEST] <wm4> but hey lets keep this crap because we're so misinformed!
[21:19:04 CEST] <nevcairiel> noone intentionally prolonged its life, but noone send a patch to remove it either
[21:19:13 CEST] <nevcairiel> someone put it under the same deprecation guards as the  API
[21:19:16 CEST] <nevcairiel> so now its tied to it =p
[21:19:48 CEST] <wm4> how about a patch that removes the implementation
[21:19:58 CEST] <wm4> or is going through pointless untested ifdeffery mandatory
[21:22:16 CEST] <nevcairiel> its a decoder, the existance of a decoder is not API
[21:23:29 CEST] <wm4> so I'll send a patch to remove them tomorrow (without the API)
[21:23:38 CEST] <wm4> and then it'll get rejected and I'll be angry
[21:24:07 CEST] <durandal_1707> JEEB: its always much slower than swscale
[21:24:32 CEST] <durandal_1707> wm4: voting!
[21:24:51 CEST] <BtbN> Hm, should I just merge the OpenCL stuff I made? Nobody seems to care.
[21:25:23 CEST] <durandal_1707> fix keyspill
[21:25:41 CEST] <BtbN> I'm thinking about putting that into an entirely seperate filter
[21:25:56 CEST] <BtbN> As it's also usefull without chroma/colorkey
[21:26:15 CEST] <durandal_1707> ok
[21:26:24 CEST] <JEEB> durandal_1707: the idea wasn't really to be faster than swscale, rather being a more correct but still fast thing
[21:26:27 CEST] <JEEB> http://up-cat.net/p/9b8d5c6b
[21:26:39 CEST] <JEEB> it seems like there's more SIMD now
[21:27:07 CEST] <durandal_1707> but results on doom9 are paradise
[21:28:38 CEST] <durandal_1707> I test bilinear only

[21:40:46 CEST] <jamrial> BtbN: if the opencl maintainers didn't comment and noone else knows much about that stuff, then go ahead i guess
[21:41:11 CEST] <BtbN> I think i'll ping it once again, and directly CC the maintainer(s)
[21:43:13 CEST] <BtbN> Great, there's a name and a GnuPG Fingerprint, but no E-Mail.
[21:44:35 CEST] <nevcairiel> wasnt there a mail in the license on top of the generic opencl header
[21:44:59 CEST] <BtbN> ah, right
[21:45:03 CEST] <BtbN> 4 E-Mails
[21:46:51 CEST] Action: ubitux smiles to nevcairiel
[21:47:57 CEST] <nevcairiel> i'm sure he'll find some obscure reason to still protest
[21:48:52 CEST] <ubitux> no i don't think so :)
[22:17:42 CEST] <jamrial> nevcairiel: derp, i thought i was replying to the license header email and not a new one about typos
[22:17:53 CEST] <jamrial> yeah, typo check on fate is silly
[22:18:38 CEST] <nevcairiel> I honestly don't even care a single bit about typos in comments
[22:18:48 CEST] <nevcairiel> and having fate break because of that? please.
