[14:49] Action: michaelni looks sadly at "CIA-40 has quit (Remote host closed the connection)"
[14:52] <ubitux> :(
[14:53] <ubitux> it's because of the heat
[14:56] <maister> So, does this sound like a bug? I am scaling a 256x224 picture to 512x224 using nearest neighbor. Then I scale that back to 256x224 again, using nearest neighbor, but the result looks different. Some colors that are not supposed to be there start to appear.
[14:59] <maister> http://i.imgur.com/Xloqi.png <- test input
[14:59] <maister> ffmpeg -i test_input.png -sws_flags neighbor -vf scale=256:224 test_output.png
[15:00] <maister> http://i.imgur.com/JJEFR.png <- test output. Notice the vertical line of red to the immediate right of the character in the middle.
[15:07] <michaelni> maister, id guess some effect from scaling with subsampled chroma
[15:07] <maister> michaelni, subsampled chroma with png?
[18:36] <Daemon404> humm
[18:36] Action: Daemon404 pokes nevcairiel 
[18:44] Action: michaelni wants to poke CIA
[18:45] <nevcairiel> Daemon404: ?
[18:45] <Daemon404> nevcairiel, can you poke x with: http://ffmpeg.org/pipermail/ffmpeg-devel/2012-August/129707.html
[18:46] <Daemon404> since he seems to have a fear of mailing lists 
[18:49] <nevcairiel> he'll just complain again about still having to have th HAVE_MMX2 alias, which apparently was his main complaint in the first place
[18:49] <nevcairiel> so i prefer to not play communications relay =p
[18:50] <Daemon404> well he doesnt wanna talk to me
[18:50] <Daemon404> so..
[18:50] <Daemon404> (nor i him, fwiw)
[18:51] <nevcairiel> just rip out the libmpcodecs thignys (and the removal of the define alias) from the patch and re-submit it if you care enough, or just drop it, i don't care
[18:51] <Daemon404> ill do the former i guess
[19:01] <nevcairiel> look at me, i probably started quite the bikeshed right now!
[19:02] <Daemon404> nevcairiel, where?
[19:02] <nevcairiel> you'll know when you read it
[19:02] <nevcairiel> i went up against the bracer police!
[19:03] <Daemon404> i tried that once
[19:03] <Daemon404> enjoy.
[19:55] <burek> sorry for asking here, but this is kinda weird and I don't know if it's a bug or intended behavior
[19:56] <burek> does this command line do what I think it does: ffmpeg -y -i 1.flv -vn audio.wav -an video.avi
[19:56] <burek> creating separate audio and video from the given input
[19:56] <JEEB> no
[19:57] <JEEB> unless it does
[19:57] <JEEB> I'm not sure if setting -an/-vn like that works
[19:57] <JEEB> I think mapping would be the thing to use there
[19:57] <Compn> who knows :D
[19:57] <burek> -map 0:a and -map 0:v ?
[19:58] <burek> ok, good suggestion, let me test it
[19:58] <burek> thanks :)
[20:05] <burek> it works :)
[20:05] <burek> thx again :)
[20:05] <burek> ffmpeg -y -i 1.flv -map 0:a audio.wav -map 0:v video.avi
[20:09] <burek> hm, I think I just found a bug :)
[23:41] <j-b> you must be nut :)
