WebApr 11, 2024 · The Opus padding mechanism provides a safe way to extend the Opus codec while preserving interoperability and without having to transmit any extra packets. [ RFC6716] specifies that all padding bytes "MUST be set to zero" by the encoder, while the decoder "MUST accept any value for the padding bytes".
WebSplitting valid Opus packets is always guaranteed to succeed, whereas merging valid packets only succeeds if all frames have the same mode, bandwidth, and frame size, and when the total duration of the merged packet is no more than 120 ms. The 120 ms limit comes from the specification and limits decoder memory requirements at a point where ...
