This enables "alternate reference frames," which allows the encoder to use frames from the future to improve the quality of current frames, particularly useful for scene transitions. Libvpx-VP9 Best Practices Summary (2026)
Hidden in temporary buffers, partially decoded frames, motion vector tables, and probability models are gigabytes of "zombie data." If left alone, these remnants will slow down the next encoding job, cause memory bloat, and eventually crash the worker node. duster libvpx
(This section would typically contain code snippets demonstrating how to initialize a VP9 encoder context using the Duster build parameters.) This enables "alternate reference frames," which allows the
