wbs: Do you happen to know why the subtitle output is not written to a dynamic buffer in hlsenc, while the ordinary output is?
<mkver>
(IIRC it can lead to crashes, because the code tries to treat the subtitle output as dynamic buffer even though it isn't.)
<wbs>
mkver: no idea, sorry
<wbs>
(I haven't touched those areas of that muxer, and very little other than those patches I just sent)
<Daemon404>
the answer for hlsenc.c is usually just that it was written bt diff people
<Daemon404>
and noone cared
<wbs>
yes
<mkver>
Ok.

I think the subtitle code in that one just crashed very easily since IIRC at some point it tried to handle it as if it had the separate segment stream open
<JEEB>
or well, mux or however you call it

lol, _mktemp() can only generate 26 filenames on windows

26 filenames should be enough for anyone

thats not exclusively a windows limitation, but of a class of implementations "Some implementations follow 4.3BSD and replace XXXXXX by the current process ID and a single letter, so that at most 26 different names can be returned."

michaelni: do you know why swscale uses a 15-bit internal representation rather than the more obvious 16-bit? are you worrying about overflow in some step? afaict the scalers already clamp, so..

but it's to avoid overflow when multiplying in filter coefficients in the next step

llyyr: if paul hasn't changed the license or requested that his work not be merged into FFmpeg, then it could be posted for review like anything else.

elenril: I hear 4-bit integers are popular these days
<courmisch>
elenril: HF is so last decade
<JEEB>
do you then NN upscale the 4bit integers?
<courmisch>
also sorry to inform you that your courmisch-free week is over
<kasper93>
human eye don't see more than 4bits
<JEEB>
4 bits at 24 frames per second. everyone knows this
<courmisch>
4 bits is for AI. For video, obviously 1 bit per pixel is enough
<JEEB>
classic dithering
<courmisch>
X11 even supports it
<courmisch>
well, X11 is lying about supporting 1, 4, 8, 15 and 16-bit pixmaps

the funniest thing about LLMS is being able to see in realtime how its thinking degrades when you increasingly quantize its neurons

concepts just get.. fuzzier
