As has been said, I have a new patchset that adds this sooner; then the internal-pointers will stay for a few days in the public context.
<jamrial>
cool

<Traneptora>
elenril: AVFrame.metadata sux sure, but how do you propose we solve the issue mkver raised
<Traneptora>
which is that Exif and AVDisplayMatrix are similar metadata
<Traneptora>
atm when I attach Exif I parse the orientation and add AVDisplaymatrix but what happens if a user changes that? how do we wish to handle it? what happens if avdisplaymatrix isn't in D4? etc.
<Traneptora>
(D4 being the dihedral group)

wbs: Why does x86/intreadwrite.h still contain a check for HAVE_MMX?
<JEEB>
röllercopter
<jamrial>
mkver: so said optimization can be disabled at configure time, i guess
<mkver>
But isn't MMX the wrong instruction set to check here?
<jamrial>
all asm used to be disabled with --disable-mmx
<jamrial>
yeah, it is, but there probably used to be some mmx impl of AV_COPY64
<jamrial>
using movq
<jamrial>
which was removed
<mkver>
Yes, by wbs, which is why I pinged him.
<j-b>
MMX Is dead :D
<Lynne>
what about 3dnow?
<Lynne>
we still have 3dnow! assembly

<j-b>
Lynne: you serious?
<j-b>
Do some linux distributions still support things without SSE?
<jamrial>
that should also be removed. same effect on state as mmx
<j-b>
Ah, a lot are now i686-without-SSE mandatory. TIL.

<Lynne>
it gets better, the only 3dnow we have left is in inline asm for mpegvideoenc
<j-b>
Not sure when, but that makes no sense anymore
<psykose>
i can almost make out more than 4 pixels

oldschool pc marketing sure was something
<Marth64>
i kept 2 of the cardboard boxes cause they were cool
<Marth64>
have a soundblaster and ATI one
<Marth64>
get your v.92 modems ready
<Gramner>
I remember SSE being marketed as "internet acceleration" because why not? that totally makes a lot of sense
<Marth64>
i still believe in Windows Vista
<Marth64>
it didn't deserve all the hate it did, maybe some of it
<Gramner>
it was called ISSE with the I being for Internet before someone came to their senses and dropped that terminology
<Marth64>
lol
<Gramner>
vista sure had issues but most of the problems were due to a) vendors selling very underpowered hardware that had no business running vista and b) terrible nvidia chipset drivers that crashed all the time
<Gramner>
if you had a decent pc with a non-nvidia chipset it was ok
___nick___ has quit [Ping timeout: 264 seconds]
<Marth64>
i was not a fan of nvidia chipset in general, i am convinced one of the nForce SATA controllers had a bug that destroyed hard drives
<JEEB>
I generally just do disable-stripping, as in most cases having optimizations has not been a problem
* sdc
ah I see I'll give that a try
<JEEB>
do note that the ffmpeg_g binary in the build root generally is one that isn't stripped as well, but disable-stripping also has the build system not strip the final binary by the name ffmpeg, or the libraries
