		const uint8_t	key[16],
		int	rounds
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/tea.h>

Аргументы

ctx	an AVTEA context
key	a key of 16 bytes used for encryption/decryption
rounds	the number of rounds in TEA (64 is the "standard")

av_tea_crypt()

void av_tea_crypt	(	struct AVTEA *	ctx,
		uint8_t *	dst,
		const uint8_t *	src,
		int	count,
		uint8_t *	iv,
		int	decrypt

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/tea.h>

Encrypt or decrypt a buffer using a previously initialized context.

Аргументы

ctx	an AVTEA context
dst	destination array, can be equal to src
src	source array, can be equal to dst
count	number of 8 byte blocks
iv	initialization vector for CBC mode, if NULL then ECB will be used
decrypt	0 for encryption, 1 for decryption
