PROFILE
Diego De Souza
During a three-month period, Daniel De Souza enhanced hardware-accelerated video processing in the ossrs/ffmpeg-webrtc and FFmpeg/FFmpeg repositories. He expanded CUDA pixel format support to include 4:2:2 formats and implemented 10-bit encoding and decoding for H.264 and HEVC on NVIDIA Blackwell GPUs, broadening compatibility and color depth. Daniel also introduced adaptive B-frame decision control for HEVC encoding, giving users greater flexibility when lookahead is enabled. His work leveraged C and CUDA programming, focusing on low-level codec development and GPU acceleration. The features delivered addressed real-world workflow needs and demonstrated a deep understanding of video encoding and processing pipelines.

Dec 1, 2025December 2025: Delivered Adaptive B-frame decision control (b_adapt) for HEVC encoding in FFmpeg/FFmpeg, enabling user control of adaptive B-frame decisions when lookahead is enabled. Implemented in avcodec/nvenc and committed as 499b5f5f92f73e5b0e6108242983695fcb6409e2 with message 'avcodec/nvenc: add b_adapt option for HEVC encoder'. No major bugs fixed this month for this repository. Overall, the feature adds valuable configurability for encoding quality and performance under lookahead, improving flexibility for users and potential gains in efficiency on hardware-accelerated paths. Technologies demonstrated include C/C++, HEVC encoding workflow, NVENC integration, and disciplined, commit-based development.
