Functions ¶
func StreamToDiscordOpus ¶
func StreamToDiscordOpus(ffmpegPath, input string, stdin io.Reader, seekSeconds float64, playbackSpeed float64, inetOnly bool) (audioFrameCh <-chan []byte, errCh <-chan error, killCh chan<- struct{})
Takes a file path/HTTP(S) stream URL and returns Discord audio frames through audioFrameCh. After audioFrameCh is closed, errCh can be read to get any potential error. Will cleanly kill ffmpeg if a struct{} is sent through killCh (IMPORTANT: only send the kill signal ONCE: there is a chance that this goroutine exits just before you send a kill signal; this will be absorbed by the channel buffer, but your program might get stuck if you try to send two kill signals to a dead stream).
