<jamrial> compnn: wouldn't that be a bug in our hevc decoder?
<compnn> i think its demux
<compnn> but i havent investigated
<compnn> all i know is apple really, enough with stuffing everything into mp4
<compnn> please just stop
<compnn> ehe @ elon musk comment 6 years ago "No. No. No."
<jamrial> can you share the sample?
<jamrial> untiled heic should work just fine
<jamrial> tiled heic is exported as separate tiles
<compnn> maybe its me? what command am i supposed to use to output the file
<compnn> not just ffmpeg -i file.heic out.jpg
<compnn> this file is tile grid, the other one that went gray was not. lets see if i can find the grey one again
<compnn> yeah its just pebcak
<compnn> i selected the gra
<compnn> Stream #0:49[0x33]: Video: hevc (Rext) (hvc1 / 0x31637668), gray(pc), 2016x1512, 1 fps, 1 tbr, 1 tbn
<compnn> Stream group #0:0[0x31]: Tile Grid: hevc (Main Still Picture) (hvc1 / 0x31637668), yuvj420p(pc, smpte170m/smpte432/bt7
<compnn> just a grayscale picture inside the file for no reason
<compnn> well for reasons that i dont need
<jamrial> compnn: you can use the xstack filter for the tile grid
<compnn> someone should write a ffmpeg docs about how to do it. probably
<compnn> as imagemagick has solved my issue already
<jamrial> the idea is to eventually have the cli do it automagically
<compnn> ah
<compnn> also i didnt know it was split up like that. i'd rather not support broken apple ideas like this
<jamrial> it's not just iphone, also samsung and probably others

<Lynne> the new apt frontend is inferior in every way
<Lynne> it is the terminal version of web 3.0
<Marth64> +1 Lynne
<Marth64> I get confused
<elenril> aptitude 4lyfe
<Lynne> list of packages is up-down-right instead of up-right-down, so you can't copy a list of alphabetically following packages
<Lynne> it won't group both updated and installed packages

<mkver> What systems actually need the sinf, cosf etc. compatibility functions in lavu/libm.h? Did requiring C11 remove support for them?
witchymary has joined #ffmpeg-devel
<jamrial> mkver: most likely. it was probably added back when we were doing c99-to-c89 madness
<mkver> It was added in fab0a8b2c6caa0e6478915bb42904995d70c4b3f without explanation.
<mkver> The "discussion" on the libav-ML was nonexistent; wbs simply lgtm'ed it.
<jamrial> then just send a patch removing most of those

<sfan5> suppose a decoder returns AVFrames that encapsulate hardware buffers, and you close the decoder. would thoses frames generally be expected to stay valid?
<Lynne> yes
<Lynne> every frame carries a ref to avhwframes which carries a ref to the device
<Lynne> neither are gone until all frames are deref'd
<sfan5> alright, ty
