<Lynne> TheVibeCoder: do you have the decompiled opencl chunks or just the opencl programs used to run the prores raw decoder?
<Lynne> I got transforms working, but I want to get the output exact
steven-netint has joined #ffmpeg-devel
<TheVibeCoder> Lynne: ghidra
<Lynne> does ghidra identify opencl embedded binary?
<TheVibeCoder> it find is as string
<TheVibeCoder> the kernels are stored as strings
<TheVibeCoder> big strings
<Lynne> lol, really? plaintext strings
<Lynne> oh wow, fucking score
<Lynne> so many separate shaders for each operation, I'd hate to know how slow it is
<Lynne> I've got 512 threads per tile
<TheVibeCoder> plaintext, need to filter out \b\t\nt and similar
<TheVibeCoder> Lynne: you cant get output exact, and codec is not lossless
<Lynne> the idea is to get the brightness to hopefully match
<Lynne> and the bands to disappear in the waveform
<TheVibeCoder> different IDCT?
<Lynne> nah, I doubt that makes a difference
<Lynne> apple are probably using their ASIC FFT/DCT processors which are definitely not bitexact with C

<averne> indecisive_turtl: sounds like a bug honestly, which driverare you encountering this with?
steven-netint has quit [Quit: Connection closed for inactivity]
<indecisive_turtl> averne: Testing with nvidia 575 on linux
<averne> I've been working on radv which has been fine. The other day I tested my entropy decode shader on nvidia and it was hanging though :')
<indecisive_turtl> lol

<Lynne> got prores raw vulkan fully working
dliu has joined #ffmpeg-devel
<Lynne> still not exact, but fucking hell its fast
lemourin has quit [Quit: The Lounge - https://thelounge.chat]
<Lynne> around 6x faster on intel, which is still too slow for realtime
<Lynne> but I can't feed it fast enough on a discrete GPU
