func DecodeSDP ¶

func DecodeSDP(in string) (webrtc.SessionDescription, error)

DecodeSDP reverses EncodeSDP.

func EncodeSDP ¶

func EncodeSDP(desc webrtc.SessionDescription) (string, error)

EncodeSDP serialises desc as JSON, zstd-compresses it, and base45-encodes the result.

func ParseSTUN ¶

func ParseSTUN(stunAddr string) error

ParseSTUN validates a STUN address of the form "host:port"

func ResolveSDPFlag ¶

func ResolveSDPFlag(value string, stdin io.Reader) (string, error)

ResolveSDPFlag returns the encoded SDP string referenced by value, validates it via DecodeSDP, and returns a descriptive error when the supplied value is unusable. value must be non-empty; callers are responsible for the "unset" branch.

A leading '@' switches to file mode: @- reads stdin, @<path> reads a file. Otherwise the value is treated as a literal encoded SDP.
