Developed interlaced video encoding support in the VDEnc AVC encoder for Xe2 and Xe3 architectures within the intel/media-driver repository, expanding hardware-accelerated processing for broadcast-ready workflows. The work involved low-level C++ development and direct integration with the VDEnc API, focusing on architecture-specific encoding pipelines to efficiently handle interlaced content. By enabling this feature, the implementation improved output quality and reduced CPU usage compared to software encoding, aligning with broader codec support goals. The developer prepared comprehensive documentation and test plans to ensure QA readiness, demonstrating a methodical approach to feature delivery and validation in driver-level video encoding environments.
