Detailed Description

Detection of available hardware resources.


Function Documentation

void hardware_init ( void   ) 

Initialize some hardware-specific variables, which are needed by other hardware_* functions.

References hardware_cores().

void hardware_memlimit_set ( uint64_t  memlimit  ) 

Set custom memory usage limit. This is used for both encoding and decoding. Zero indicates resetting the limit back to defaults.

References memlimit_custom.

uint64_t hardware_memlimit_encoder ( void   ) 

Get the memory usage limit for encoding. By default this is 90 % of RAM.
