* fix(record): Improve OpenCV backend handling for Windows systems * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Resolved ruff's E402 error (import statements not at the beginning of the file): - Moved all import statements to the beginning of the file - Defined _fix_opencv_backend() as a function - Adjusted the timing of the fix call - Code structure conforming to ruff * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix(record): Correct OpenCV backend for Windows systems * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix(opencv): Set OpenCV environment variable for Windows systems * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix(opencv): Refactor MSMF hardware transform environment variable setting for Windows * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
