Abstract

A method for context-dependent in-call video codec switching includes receiving an indication that a far-side endpoint includes a capability to switch from an initial video codec to a secondary video codec during a call. During a call with the far-side endpoint, the method includes determining that a performance of an encoder satisfies a codec switching threshold. The codec switching threshold indicates that the performance of the encoder justifies switching from the initial video codec mid-stream of the call. During a call with the far-side endpoint, the method also includes switching from the initial video codec initially negotiated to govern the call to the secondary video codec.
