# Introduction
|
|
|
|
For test purposes, environment variables can be set to control libyuv behavior. These should only be used for testing, to narrow down bugs or to test performance.
|
|
|
|
# CPU
|
|
|
|
By default the cpu is detected and the most advanced form of SIMD is used. But you can disable instruction sets selectively, or completely, falling back on C code. Set the variable to 1 to disable the specified instruction set.

# Test Width/Height/Repeat
|
|
|
|
The unittests default to a small image (128x72) to run fast. This can be set by environment variable to test a specific resolutions.
|
|
You can also repeat the test a specified number of iterations, allowing benchmarking and profiling.
|
|
|
|
set LIBYUV_WIDTH=1280
|
|
set LIBYUV_HEIGHT=720
|
|
set LIBYUV_REPEAT=999
|
|
set LIBYUV_FLAGS=-1
|
|
set LIBYUV_CPU_INFO=-1
