The Silent Janitor: How Duster LibVPX Cleans Up Video’s Messy Pipeline

Duster is the windshield wiper. It acknowledges a hard truth: Even elegant codecs leave behind messes. And sometimes, the most important tool in the stack isn’t the encoder—it’s the silent janitor that follows it, making sure the next job starts with a clean slate. duster libvpx

They traced it to LibVPX’s vpx_codec_enc_config_t structure. The encoder was reusing a configuration object but not resetting the rc_min_quantizer and rc_max_quantizer internal states. A developer wrote a simple Duster routine: The Silent Janitor: How Duster LibVPX Cleans Up

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. A developer wrote a simple Duster routine: Hidden
