This pull request introduces several significant changes to the video processing pipeline, environment configuration, and transcoding logic. The main improvements include downloading source videos to local disk before processing, updating environment and performance tuning variables, simplifying the transcoding logic by removing the per-title VMAF complexity probe, and enhancing audio stream metadata handling. Additionally, new audio ABR profiles are introduced.
