Module link 

The link between the media engine and whatever captures, encodes, decodes and paints video (a webview over a loopback socket, or an in-process port). Binary messages, the first byte says what follows.

Enums

FromLink

Received from the encoder side of the link.

LinkMsg

What one link message is.

ToLink

Sent to the encoder side of the link.

Constants

KIND_CONTROL

A JSON control message.

KIND_FRAME

A video frame: the 16-byte wire header, then the encoded bytes. The same bytes go on the QUIC stream, so nothing is re-framed in between.

KIND_PCM

Raw audio from a screen share: a 5-byte header (sample rate u32, channels u8) and interleaved little-endian f32 samples. Cancelled and encoded on the other side.

PCM_HEADER_LEN

Functions

control

A control message ready to send to the encoder side.

parse

Parses a message from the encoder side. frame is the header plus payload, the exact bytes to put on the wire.
