[00:00:39 CET] <edgy> JEEB: so complicated that I couldn't swallow this at all! based upon whatever could be based upon!
[00:01:26 CET] <JEEB> basically, as long as it's considered a modification of an existing patent it's a'ok or something
[00:01:49 CET] <JEEB> so if you work around a patent knowingly or unknowingly, it can be modified to also apply to your way of doing it
[00:02:53 CET] <edgy> JEEB: but this is something that is very difficult to measure, every new invention is a modifiction of a previous one in some way or another
[00:03:27 CET] <JEEB> yes, and then the patent office decides whether or not the thing is different enough from prior art
[00:03:31 CET] <JEEB> or an improvement or whatever
[00:03:38 CET] <JEEB> but that's when you are applying for a new patent
[00:03:48 CET] <JEEB> modifying a patent is a different thing methinks
[00:06:29 CET] <edgy> JEEB: so if vc1 got it patented, then misubishi modified its patent, they can canel vc1 acquired patents? oh! my head
[00:07:25 CET] <JEEB> no, the point is that if the patent applies to the format, then mitsu could start asking for licensing fees
[00:07:32 CET] <JEEB> simple as that
[00:07:44 CET] <JEEB> and not only had to be originally written like that, but they can even edit it
[00:08:51 CET] <edgy> this is complete trash!
[00:09:03 CET] <JEEB> :D
[00:10:07 CET] <edgy> JEEB: so now what do normally use to encode your dvd's? with this bad vp9 situation shall I just use x265?
[00:10:27 CET] <JEEB> at this point x264
[00:10:37 CET] <JEEB> because you'd have to test if x265 is worth the wait for you
[00:11:03 CET] <JEEB> MCW never got a real developer community around x265
[00:11:11 CET] <JEEB> (MCW being the company that licensed the name from x264 LLC)
[00:11:37 CET] <JEEB> so it does improve, but it's definitely hard to beat x264 in stuff like detail retention with higher bit rates
[00:12:03 CET] <JEEB> I will say though, that if you are aiming just for lower bit rates then libx265 is already better than libx264. both look like shit, and x265 gives you less shit.
[00:12:16 CET] <JEEB> but if you want to go to the area where one looks not shit, then usually x264 hits that line quicker
[00:13:01 CET] <JEEB> also this reminds me that I should do another test with 10bit x265
[00:16:11 CET] <edgy> JEEB: thanks a lot will stick to that. Is it safe just to use ffmpeg -i input -c:v libx264 -preset medium -crf 26 output.mp4 for all my videos? I am not an expert here
[00:16:39 CET] <JEEB> use -ss and -t to encode like 5 minutes of footage
[00:16:44 CET] <JEEB> test various crf values
[00:16:48 CET] <JEEB> start at 23
[00:16:52 CET] <JEEB> if it looks bad, go down
[00:16:57 CET] <JEEB> if it looks good, go up
[00:17:08 CET] <JEEB> then when you get the highest value that still looks good enough for you
[00:17:11 CET] <JEEB> use that
[00:17:19 CET] <JEEB> preset medium is a'OK
[00:17:51 CET] <furq> 26 is pretty high
[00:18:04 CET] <JEEB> that's why I said start with 23
[00:18:14 CET] <JEEB> and then go up/down depending on the short clip's results
[00:18:28 CET] <furq> 23 is also pretty high but i guess it does the job
[00:18:31 CET] <JEEB> that way you don't waste time and find your workable value
[00:18:39 CET] <JEEB> the idea is to start with something that might not look perfect :P
[00:18:49 CET] <JEEB> otherwise you start so low you don't know if it's bad or not yet
[00:19:59 CET] <furq> filtering is often more important with dvd anyway
[00:20:18 CET] <edgy> JEEB: I tried 26 and couldn't see a difference. is this because I am not trained to notice details or because the videos are low quality I don't know
[00:20:42 CET] <JEEB> edgy: could just be the content too
[00:20:46 CET] <JEEB> it's content dependent
[00:21:06 CET] <JEEB> also make sure you are actually testing the short clip how you'd actually watch it
[00:21:28 CET] <edgy> JEEB: what do you mean by short clip?
[00:21:46 CET] <JEEB> use -ss and -t
[00:21:48 CET] <JEEB> ss seeks
[00:21:55 CET] <JEEB> t limits how much it encodes
[00:22:05 CET] <JEEB> you don't usually encode a full clip when picking settings
[00:22:19 CET] <edgy> JEEB: oh! I didn't know that
[00:22:20 CET] <JEEB> of course if the whole clip encodes quickly enough then you can do without that :P
[00:22:27 CET] <JEEB> but yunno
[00:22:33 CET] <JEEB> it's a good general hint
[00:22:42 CET] <JEEB> because people usually complain they don't have the time to test different values
[00:22:48 CET] <furq> you'll definitely want to do that when you're testing different presets
[00:23:16 CET] <JEEB> also do note that the same CRF value does not mean the same thing between a) different types of content and b) different presets
[00:23:17 CET] <edgy> JEEB: and for the audio, are the defaults to use aac or copy? should I specify a bitrate like 128 or 160 or what?
[00:23:19 CET] <furq> 480p at medium should be much faster than realtime on any modern cpu, but veryslow won't
[00:23:25 CET] <JEEB> edgy: unless you need to re-encode, don't
[00:23:37 CET] <furq> yeah keep ac3 audio unless you need browser compatibility or something
[00:23:54 CET] <JEEB> furq: I remember laughing out loud when 720p encoded at like 8fps with preset placebo
[00:23:56 CET] <furq> it's usually not worth the space saving
[00:23:58 CET] <JEEB> on my 4790K
[00:24:02 CET] <furq> nice
[00:24:21 CET] <JEEB> I still remember encoding on an old Athlon XP and Turion 64x2
[00:24:30 CET] <furq> fwiw for dvd i normally use -preset slower -bf 5 -subq 10 -crf 20
[00:24:40 CET] <furq> but yeah filtering is generally more important than the settings you use
[00:24:53 CET] <edgy> furq: why you mentioned ac3? I guess it was mp3
[00:24:56 CET] <furq> unless it's a pal film dvd or something
[00:24:59 CET] <furq> because you said dvd
[00:25:13 CET] <edgy> furq: so all dvd's are ac3?
[00:25:27 CET] <furq> ac3, dts, lpcm or mp2
[00:25:50 CET] <furq> 99% of them are ac3 though
[00:26:12 CET] <edgy> furq: so, I would leave it as it's because I thought mp4 works well with aac and might not play with other audio codecs
[00:26:27 CET] <furq> ac3 is supported in mp4
[00:26:31 CET] <furq> maybe not my browsers though
[00:26:38 CET] <furq> s/my/by/
[00:27:08 CET] <edgy> furq, JEEB and all I learned a lot from you today. It's my first time using ffmpeg and really thank you
[00:27:32 CET] <furq> we haven't even got onto deinterlacing and IVTC yet
[00:27:35 CET] <edgy> JEEB: is there something like best practices doc?
[00:27:49 CET] <furq> or properly demuxing titles
[00:27:56 CET] <edgy> furq: if you have the patient to tell me I will love it ;)
[00:28:16 CET] <furq> well i'm in a pal region so i don't know shit about IVTC
[00:29:04 CET] <furq> `-vf yadif=1` is as good as ffmpeg has got for deinterlacing
[00:29:18 CET] <furq> that's not really a thing for film dvd though
[00:30:53 CET] <edgy> furq: when people speak about pal/secam/ntsc I got lost because I play videos in my pc not a tv so I don't even know why that matters
[00:31:20 CET] <furq> pal dvd is 25fps 720*576, ntsc is 30(ish) fps 720*480
[00:31:42 CET] <furq> film is 24fps so how you get that onto a dvd varies depending on the region
[00:31:49 CET] <furq> pal is normally sped up by 4%, ntsc is telecined
[00:32:29 CET] <furq> the first one of those is significantly easier to deal with
[00:34:13 CET] <furq> that only applies to film, tv shows were often shot on video which is normally just 50i/60i, so it's the same either way
[00:34:44 CET] <edgy> furq: how can i tell what kind of dvd I have currently?
[00:35:03 CET] <furq> watch it in mpv
[00:35:08 CET] <edgy> furq: and?
[00:35:29 CET] <furq> http://www.doom9.org/images/Interlace.jpg
[00:35:33 CET] <furq> look for that sort of thing
[00:35:51 CET] <furq> hit . to step frame-by-frame
[00:36:18 CET] <furq> if it happens on some frames with movement at regular intervals, it's telecined
[00:36:24 CET] <furq> if it happens on every frame with movement it's interlaced
[00:36:34 CET] <furq> otherwise it's either been deinterlaced already or it's pal film
[00:38:53 CET] <edgy> furq: you previously complained that every one know mpv better than you. certainly not me. where did you get this .to from?
[00:41:29 CET] <furq> .to?
[00:41:50 CET] <edgy> furq: I don't have a dvd handy now but I have .VOB file in VIDEO_TS folder so I tried . in mpv and it seems it jumps frame by frame
[00:42:05 CET] <edgy> furq: you told me to try ".to" in mpv?
[00:42:18 CET] <edgy> furq: ah!
[00:42:27 CET] <edgy> furq: you mean the . sorry
[00:42:32 CET] <furq> ok good
[00:42:37 CET] <furq> that would have been embarrassing
[00:42:42 CET] <edgy> furq: yes the . now shows that effect
[00:42:54 CET] <furq> i don't normally use mpv, but my regular player deinterlaces automatically and it's a pain to turn it off
[00:43:00 CET] <furq> so this is one of the things i use mpv for
[00:43:27 CET] <edgy> furq: I am rereading your steps again ...
[00:44:08 CET] <furq> you probably also want to check the resolution/framerate
[00:44:08 CET] <edgy> furq: i see that effect when the frame has something moving fast
[00:44:20 CET] <furq> all ntsc dvds are 480p, 29.97fps
[00:44:33 CET] <furq> if it's not ntsc then it won't be telecined
[00:45:34 CET] <edgy> furq: this is stuff is so complicated for me
[00:46:06 CET] <edgy> I guess it's better to leave it since I don't want to annoy you
[00:47:15 CET] <edgy> furq: just if you recommend me to read something like best practices or faq, I will appreciate it
[00:55:06 CET] <edgy> furq: ok again thanks a lot will save this so I re-read it again, bye for now
[02:10:18 CET] <wodim> anybody knows if there's anywhere I can grab a recent package of ffmpeg for ubuntu xenial?
[02:17:06 CET] <KurousagiMK2> https://launchpad.net/~mc3man/+archive/ubuntu/ffmpeg-test
[02:19:02 CET] <wodim> a bit late, I decided to compile it and the binary is being linked as we speak
[02:19:11 CET] <wodim> I looked at that, I didn't like the /opt thing

[02:54:04 CET] <KCat156> Hello! I want to use ffprobe to find the displaymatrix of a video, but in an easily parsable way.
[02:55:14 CET] <KCat156> I've tried to use show_entries, but I don't know how to specify the entry for the displaymatrix because it is in a section within a section
[02:56:57 CET] <llogan> ffprobe -loglevel error -show_entries side_data=displaymatrix -of default=nw=1 input.foo
[02:57:22 CET] <llogan> or "default=nw=1:nk=1"
[02:57:56 CET] <KCat156> That worked! Thanks!
[03:01:10 CET] <llogan> ]\
[03:01:38 CET] <llogan> ^ Wrong console syndrome.
[03:26:30 CET] <kurufu> So, if i have a video with non-square pixels (SAR 8:9, DAR 4:3), is there a setting to square up the pixels when re-encoding?
[03:26:45 CET] <kurufu> encoding as I normally would resulted in a squashed image.
[03:27:07 CET] <kurufu> meanwhile ffplay and all other plays present the image as I would expect.
[03:27:20 CET] <kurufu> (present the image of the original video, the rencoded one is squashed).

[03:48:24 CET] <teratorn> TestIrchatNICK: quote everything so that your argument to filter_complex is one thing
[03:50:59 CET] <TestIrchatNICK> teratorn   Can you give me an example? Thank you
[03:52:02 CET] <teratorn> -filter_complex expects one thing to follow it, you're trying to pass it two things
[04:12:38 CET] <kurufu> Well to answer my question, to get sar and dar set properly when re-encoding. Use -vf setsar=sar,setdar=dar. But wtf why is this not the default why does it reshape pixels if I dont put this?!

[05:00:03 CET] <zpc> Hi! the duration of source video and substracted wav is different , why?
[05:01:51 CET] <zpc> ffmpeg -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -vn test.wav -y
[05:03:25 CET] <zpc> I'm recorgnizing subtitle from audio, and I need to add subtitle back to video. So I want the duration of audio and video the same
[05:14:05 CET] <kurufu> zpc: set the samplerate correctly and it should fix your problem
[05:14:53 CET] <kurufu> It looks like its taking the 44.1 input and outputing 48. Or that is just a devilish coincidence of time reduction
[05:17:59 CET] <zpc> kurufu: I run ffmpeg -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -b:a 44.1k -vn test.wav -y
[05:18:06 CET] <zpc> and the result is the same
[05:21:01 CET] <kurufu> Hmm
[05:23:04 CET] <kurufu> oh you use -b:a
[05:23:11 CET] <kurufu> you need ot use... I think -ar? for sample rate
[05:25:03 CET] <zpc> ffmpeg -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -ar 44.1k -vn test.wav -y
[05:25:14 CET] <zpc> Duration: 00:06:10.40, bitrate: 705 kb/s
[05:25:20 CET] <zpc> result the same :(
[05:25:38 CET] <zpc> I'm very confusing
[05:29:17 CET] <kurufu> well im at a loss lol. Im not to proficient at ffmpeg myself.
[05:30:01 CET] <kurufu> but if it makes you feel better my ffmpeg is doingthe same thing :)
[05:30:50 CET] <zpc> kurufu: No problem, thank you all the same !
[05:50:52 CET] <dr_pardee> zpc: it's the conversion to wav that causing the timing issue. ffmpeg -y -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -vn -acodec copy -bsf:a aac_adtstoasc test.m4a
[06:31:07 CET] <KCat156> How can I rotate an mp4's metadata in ffmpeg? Re-encoding the video is too slow.
[06:49:24 CET] <Prelude2004c> hey guys.. running with ffmpeg -i rtmp://localhost/whatever/whatever.. logs show it gets to " sending play command for 'stream' " but then nothing else
[06:49:29 CET] <Prelude2004c> just sits there.. anyone have any idea why?
[06:59:48 CET] <MrMonkey31> KCat156: the param you want to set is -metadata:s:v
[07:00:21 CET] <MrMonkey31> ex, -metadata:s:v "rotate=90" for a (I think) left hand quarter turn
[07:01:21 CET] <MrMonkey31> and of course -c copy

[08:54:29 CET] <IamTrying> ItWasntMe2013: but i just want be god level on FFmpeg on old versions, its not important i have to sync myself with nightly builds. On one old version i want to make my skill as god level in FFmpeg. there are too many random FFmpeg informations and that confuse the research.

[09:04:34 CET] <IamTrying> donate is natural for me, but i need it my way, i have to feel like i was helped by ffmpeg, still not yet i was helped by it ItWasntMe2013

[12:21:04 CET] <sunny26> Compile on my X86_64 platform
[12:21:06 CET] <sunny26> !!!
[12:21:12 CET] <sunny26> ok...
[12:21:21 CET] <sunny26> let me check...
[12:59:28 CET] <sunny26> Hi <BtbN> still its vailing with the error Test source failed. Look at tests/data/fate/source.err for details.
[12:59:52 CET] <sunny26> And When I open it, its blank
[12:59:55 CET] <sunny26> :-(
[13:13:54 CET] <sunny26> Hi guyz
[13:14:26 CET] <sunny26> While running "make fate" I am getting error like "Look at tests/data/fate/source.err"
[13:14:39 CET] <sunny26> And when I opens it, it is blank
[13:15:17 CET] <sunny26> Is there anything needed to be downloaded before we run the fate suite
[13:15:18 CET] <sunny26> ??
[13:15:23 CET] <sunny26> Please Help
[13:24:26 CET] <durandal_170> sunny26: what are you submitting?
[13:29:01 CET] <nonex86> well, i asked about this before, but i still hope another way exists... its about seeking using ffmpeg on mpegps files, as far as i understand i CANT seek this kind of files to the timestamps
[13:29:22 CET] <nonex86> so right now i just read frames from file till i find pts i needed
[13:29:49 CET] <nonex86> it take some time on big files
[13:30:38 CET] <nonex86> is there are any way to make the process faster?
[13:57:25 CET] <wodim> sunny26, I have no clue, but I don't think you can run the test suite if you're cross compiling
[14:02:40 CET] <termos> are there any good example of using the tee muxer from the libavformat API?
[14:06:35 CET] <sunny26> <wodim> : I am not cross compiling
[14:06:48 CET] <wodim> you just said you are
[14:06:53 CET] <sunny26> I am now compiling it on my onw PC
[14:07:28 CET] <sunny26> Yes I had cross compiled it because i have test my hardware also, that's another story
[14:07:42 CET] <sunny26> make fate-rsync SAMPLES=fate-suite/
[14:07:50 CET] <sunny26> rsync -vrltLW --timeout=60 --contimeout=60 rsync://fate-suite.ffmpeg.org/fate-suite/ fate-suite/
[14:07:56 CET] <sunny26> rsync: safe_read failed to read 1 bytes [Receiver]: Connection reset by peer (104)
[14:08:02 CET] <sunny26> rsync error: error in rsync protocol data stream (code 12) at io.c(251) [Receiver=3.1.0]
[14:08:09 CET] <sunny26> make: *** [fate-rsync] Error 12
[14:08:15 CET] <wodim> well there you have your error
[14:09:06 CET] <sunny26> But i dont understan it what is going wrong ?
[14:09:21 CET] <sunny26> I have enough memory on my PC
[14:09:27 CET] <wodim> there was an error connecting to the rsync server
[14:09:49 CET] <sunny26> So what should i do now ?
[14:10:03 CET] <wodim> what do you do when you try to download something and it fails?
[14:10:25 CET] <sunny26> donot know...
[14:10:33 CET] <wodim> you try again
[14:10:37 CET] <sunny26> please suggest
[14:10:46 CET] <DelphiWorld> hey
[14:10:56 CET] <sunny26> oh great.. Tried 4-5 times
[14:11:01 CET] <DelphiWorld> someone able to transcode hd video  from tvheadend?
[14:11:16 CET] <wodim> sunny26, maybe your connection is not working well, or maybe the remote ffmpeg server is having problems
[14:11:38 CET] <sunny26> Ok.. Will try it tomorrow then
[14:11:48 CET] <sunny26> Hope your suggesion works
[14:15:11 CET] <sunny26> <wodim> at http://fate-suite.ffmpeg.org/ the fate-suite folder doesn't exit !
[14:15:18 CET] <sunny26> can you look at it ?
[14:15:34 CET] <wodim> that's http
[14:15:40 CET] <wodim> rsync is another protocol
[14:15:42 CET] <sunny26> So ?
[14:15:45 CET] <wodim> it does not have to appear there
[14:15:46 CET] <sunny26> ok
[14:15:55 CET] <wodim> the error message clearly indicates a connection problem
[14:16:01 CET] <sunny26> ok ok
[14:16:50 CET] <sunny26> So where it should be available ?
[14:17:01 CET] <sunny26> can I "wget" it  ??
[14:17:57 CET] <sunny26> I am submitting my first patch in ffmpeg community. The last part remainig is "make fate".
[14:18:20 CET] <wodim> maybe you can. I don't know
[14:18:24 CET] <DelphiWorld> wodim: isn't wodim a cd riping app or something?
[14:18:38 CET] <wodim> a cd burning app
[14:18:43 CET] <DelphiWorld> lol
[14:18:47 CET] <wodim> I liked the name so I kept it
[14:18:49 CET] <DelphiWorld> HAHAHA i could remember it ;)
[14:18:55 CET] <DelphiWorld> i see
[14:19:01 CET] <DelphiWorld> WOW! DIM!
[14:22:12 CET] <c_14> sunny26: does fate pass without the samples? what are you patching?
[14:27:27 CET] <sunny26> means ?
[14:27:33 CET] <sunny26> only make fate !
[14:27:50 CET] <sunny26> <c_14> you me "make fate" ?
[14:27:52 CET] <c_14> yes
[14:27:56 CET] <sunny26> *mean
[14:27:58 CET] <sunny26> no
[14:28:04 CET] <sunny26> error is as below
[14:28:18 CET] <sunny26> Test source failed. Look at tests/data/fate/source.err for details.
[14:28:38 CET] <sunny26> cat tests/data/fate/source.err
[14:28:43 CET] <sunny26> It shows nothing
[14:28:48 CET] <sunny26> its blank
[14:30:05 CET] <sunny26> I have executed "make fate" before refering to https://ffmpeg.org/fate.html
[14:33:50 CET] <durandal_170> sunny26: that fate thing might not be needed
[14:34:32 CET] <durandal_170> what are you actually doing regarding your patch you wish to send?
[14:35:13 CET] <sunny26> <durandal_170> : I am adding support for nv12 tile format conversion to nv12 and yuv420p
[14:35:22 CET] <sunny26> Its done, and tested.
[14:35:37 CET] <sunny26> Only one last thing remainig in my checklist is "make fate".
[14:35:49 CET] <sunny26> What should I do ?
[14:36:16 CET] <durandal_170> you can run fate without samples
[14:36:35 CET] <sunny26> Ok but its failing
[14:37:02 CET] <durandal_170> only if you add/change codecs/formats that's relevant
[14:37:24 CET] <durandal_170> sunny26: woks fine here
[14:38:33 CET] <durandal_170> maybe you connection have special rules
[14:39:05 CET] <sunny26> http://pastebin.com/wDTqM0KT
[14:39:13 CET] <sunny26> this error
[14:40:57 CET] <sunny26> <durandal_170> What am missing ?
[14:41:25 CET] <durandal_170> sunny26: valid connection
[14:41:37 CET] <sunny26> :-))
[14:41:40 CET] <sunny26> ok
[14:42:38 CET] <durandal_170> sunny26: your headers are missing guards
[14:43:06 CET] <durandal_170> look at other headers
[14:43:20 CET] <c_14> And license headers
[14:45:03 CET] <sunny26> Ok let me investigate again.
[17:51:06 CET] <MrMonkey31> my head hurts a lot after trying to use filter graphs
[17:51:26 CET] <MrMonkey31> one persistent error I seen is "Input link in1:v0 parameters (size 946x532, SAR 1:1) do not match the corresponding output link in0:v0 parameters (946x532, SAR 255:254)"
[17:52:42 CET] <MrMonkey31> I've decided that I need setsar=sar=1 but inserting this in a logical (to me) manner fails, as does inserting it at all steps of the filtering
[17:53:17 CET] <MrMonkey31> the error's from the line [vr][blended]concat=n=2[fin]
[17:54:43 CET] <MrMonkey31> depending on which input file I choose I have also seen 'in1:v0 parameters (size 946x532, SAR 4256:4257)' and wondered, what's it all mean?
[18:03:01 CET] <agrathwohl> Anyone know of a good place to get color test frames for Rec 709?
[18:03:09 CET] <agrathwohl> Can FFmpeg generate them?
[18:41:19 CET] <MrMonkey31> wow, an hour-long ordeal has ended.  apparently the only thing to fix my complex filter was to put setsar=r=1 on a separate line
[19:23:48 CET] <GuiToris> hello, could anyone tell me why I can't run this command ffmpeg -f concat -i mylist.txt -c copy output.mkv ? 'Unsafe file name'
[19:27:15 CET] <c_14> add -safe 0 before -i
[19:37:54 CET] <GuiToris> c_14, yes it does the trick, but is it the standard way to execute this command?
[19:38:21 CET] <c_14> that or ensure that the paths in mylist.txt are relative
[19:38:56 CET] <GuiToris> they are, I just followed the wiki and I created the list with for f in ./*.wav; do echo "file '$f'" >> mylist.txt; done
[19:39:44 CET] <c_14> I don't really get how the safe paths thing works
[19:39:56 CET] <GuiToris> c_14, no problem, thank you for your help :)
[19:40:02 CET] <c_14> as long as you're not processing untrusted input use -safe 0
[19:40:15 CET] <GuiToris> got it :)
[20:53:33 CET] <sunny26> Hi guyz I wanna submit a new patch to ffmpeg,  but I am stuck with "make fate" error http://pastebin.com/0Pm5Zy3n
[20:53:39 CET] <sunny26> Please help
[20:54:20 CET] <sunny26> same thing I also posted on the mailing list on this link http://ffmpeg-users.933282.n4.nabble.com/make-fate-is-failing-td4678569.html
[20:55:16 CET] <sunny26> I am subbmiting  a patch for the first time,  please help me out.
[20:57:30 CET] <c_14> you're missing inclusion guards
[20:59:05 CET] <sunny26> "you're missing inclusion guards" please elobrate !
[20:59:23 CET] <c_14> #ifndef AVUTIL_AES_H #define AVUTIL_AES_H
[20:59:26 CET] <c_14> ^those
[20:59:31 CET] <sunny26> Oh
[20:59:36 CET] <sunny26> let me see
[21:00:02 CET] <sunny26> ya true...
[21:02:13 CET] <c_14> should be AVUTIL_SPECIAL_FORMAT_H/SWSCALE_NV12TILED2NV12_H I think
[21:03:33 CET] <sunny26> ok
[21:04:27 CET] <durandal_1707> sunny26: development talk is on #ffmpeg-devel
[21:07:51 CET] <sunny26> ok sorry.
