Yes. > Salsify uses a purely functional video codec to achieve this. Our video codec is 100% conformant with the Google VP8 format, but has one major trick: the encode and decode functions are purely functional, with no side effects, and represent the inter-frame “state” of the decoder explicitly. This allows Salsify to make the encoder compress a frame relative to an arbitrary decoder state, allowing the application to safely skip frames on output from the encoder, not just on input.
