question about the message "Use --disable-x86asm for a crippled build." What does "crippled build" mean? For context, I have found a FATE test that fails when configure is run with the disable-x86asm flag, but is that expected/allowed since it running against a "crippled" build ?
<Lynne>
it means it'll be a very slow build
<Lynne>
definitely not expected, which test fails?

it'll go through at least 1 more revision anyway

Lynne: is there any news about the vp9 decode spec?
<Lynne>
it'll happen, there's plenty of interest, but we're all very busy until we release av1 encode
<llyyr>
ah i see
<Lynne>
there's already plenty of code written though
<Lynne>
collabora wrote driver code for a mesa extension, and I think dave had a vp9 decode ffmpeg branch

hello, it's a bit of a loose question but I've been asked to figure out what filters and plugins get instantiated in ffmpeg when I play a certain video stream, is there any way from code or otherwise to find out exactly?
<BtbN>
as long as you don't tell it to filter, there won't be much. Maybe some colorspace/pixel format conversion if neccesary, but that's about it
<BtbN>
and ffmpeg does not have plugins
<King_DuckZ>
I think we call plugins that kind of virtual class emulation mechanism, for example in mpegts.c at the bottom there are these structs of function pointers
<King_DuckZ>
I'm not entirely sure where they get called from exactly but if there's a place that has the full set of everything, it'd be great if I could quickly loop over them and printf() their name

Lynne: fate-filter-fps-cfr fails when configured with disable-x86asm. I am on an intel mac, which also may be a factor? I can make a bug report, I just wanted to clarify about "crippled build" first.
<Sean_McG>
hmmm, that shouldn't happen
<Sean_McG>
have a configure line I can check that on Linux with? it should be OS-agnostic
<Sean_McG>
OK yes, can confirm that fate-filter-fps-cfr fails on Linux as well with --disable-x86asm, so go ahead and open a bug ticket
ngaullier has quit [Quit: Leaving]
<Sean_McG>
the non-CFR version of that test fails as well

ok, silly q about bug reports- "Only send bug reports there if you also intend to provide a fix." I'm not confident I am currently able to provide a fix for the borked-with-disable-x86asm test. also… I must be missing something because I can't seem to register (yes, this is my first bug report).
<Sean_McG>
ouch, who wrote that
<Daemon404>
where is that written? that can't be right for trac
<Sean_McG>

<Daemon404>
ok found it... that's referring to the developer mailing list
