## Backward Compatibility
No code changes may be introduced that would regress support for any currently supported hardware.
All contributions must ensure continued compatibility and functionality across all supported hardware platforms.
Failure to maintain hardware compatibility may result in the rejection or reversion of the contribution.
Any deliberate modifications or removal of hardware support will be transparently communicated in the release notes.
API options are solely considered as a stable interface.
Any debug parameters, environmental variables, and internal data structures, are not considered as an interface and may be changed or removed at any time.
## Known Issues and Limitations
1. Intel(R) Media Driver for VAAPI is recommended to be built against gcc compiler v6.1
