[01:47:00 CEST] <BBB> atomnuker: <3 nice work
[06:53:31 CEST] <atomnuker> for some reason the timestamps out of the decoder are INT64_MIN
[06:53:54 CEST] <atomnuker> I think I need to specialcase atrac9 in utils.c like the other atrac codecs ;/
[11:08:46 CEST] <kaot> Hi everyone! Quick question: I submitted a patch set (libavformat/aadec) several days ago. I wonder what's going to happen with it? Do I need to find a sponsor or something to get it included into the codebase?
[11:09:49 CEST] <durandal_1707> just bump patch with new mail requesting action for  it after several days
[11:13:43 CEST] <kaot> ok, thanks, will do
[13:46:27 CEST] <atomnuker> michaelni: could you upload https://pars.ee/temp/atrac9_fate.tar.gz to fate? I've sent a patch to add a atrac9 testing
[14:03:14 CEST] <JEEB> atomnuker: ooh, test samples :D
[14:27:26 CEST] <j-b> awesome
[14:46:05 CEST] <michaelni> atomnuker, test fails on qemu mips. Before uploading, am i correct that making the samples smaller is not a good idea ? 
[14:46:22 CEST] <michaelni> about the failure see ML i just posted it
[15:07:02 CEST] <DXK77> I am trying to extract image from .mp4 file, but it just mangled the .png output filename from the batch file
[15:08:17 CEST] <jdarnley> Batch file huh?  Are you aware that % is a special character in them?
[15:08:21 CEST] <atomnuker> michaelni: yeah, I knew they would, sample 2 uses PNS which needs random numbers, which the lfg outputs
[15:08:29 CEST] <DXK77> Could not open file : outputC:\ffmpeg\1.bat5d.png
[15:08:53 CEST] <jdarnley> Yep.  Learn to work your shell.
[15:09:12 CEST] <DXK77> is there a frontend for ffmpeg that can extract specific timecodes
[15:10:28 CEST] <DXK77> why won't this work in batch file?  "C:\ffmpeg\bin\ffmpeg.exe" -i "input.mp4" "frames/out-%03d.jpg"
[15:12:15 CEST] <jdarnley> Because %0 gets substituted for the 0th argument to the batch file
[15:15:06 CEST] <jdarnley> If you want to learn more I suggest this website https://ss64.com/which I have found extremely useful in the past.
[15:15:19 CEST] <jdarnley> And take all further support questions to #ffmpeg
[15:15:38 CEST] <jdarnley> I mean https://ss64.com/
[15:15:45 CEST] Action: jdarnley curses his spacebar
[15:15:53 CEST] <DXK77> thanks! much appreciated :)
[16:55:14 CEST] <michaelni> atomnuker, the lfg should output the same numbers on mips and x86, or did i misunderstand what you meant ?
[17:19:49 CEST] <atomnuker> michaelni: the lfg is float-based, so that's not guaranteed
[17:20:07 CEST] <atomnuker> or maybe its the imdct which is non bitexact
[17:20:23 CEST] <atomnuker> anyway, it needs a fuzz value so now I know about how much it ought to be
[17:20:29 CEST] <michaelni> i thought you meant the integer one
[17:21:00 CEST] <atomnuker> no, I'm using the float one, not the alfg or mlfg variants, those output 32bit uints
[17:21:51 CEST] <atomnuker> I've asked someone to decode the files with the reference decoder to see how they compare, though if someone here has a windows machine handy and wants to help I can send the binaries over
[17:25:45 CEST] <michaelni> not me, my windows box has not been used for years, but ill test with the updated ref files when i see them
[17:27:25 CEST] <atomnuker> thanks
