Worked on the libsdl-org/aom repository, focusing on AV1 codec development and video encoding enhancements using C. Delivered an improved Temporal Prediction Layer data handling feature for rate control, leveraging the source buffer from the previous GOP to optimize both external and built-in rate control, which improved encoding performance and quality metrics. Addressed stability and compatibility by fixing reconstruction buffer handling, refining UV intra prediction for high bit depth and subsampling, and simplifying tile area constraints for better platform support. Further improved encoder reliability by correcting reference frame index mapping in the temporal prediction model, reducing artifacts and enhancing encoding quality.
