SecondsToClockTime converts seconds to seconds relative time.

func ServeTranscodedStream

func ServeTranscodedStream(w io.Writer, input interface{}, ff *exec.Cmd, ffmpegPath, subs string, seekSeconds int) error

ServeTranscodedStream passes an input file or io.Reader to ffmpeg and writes the output directly to our io.Writer.

func StreamURL

func StreamURL(ctx context.Context, s string) (io.ReadCloser, error)

StreamURL returns the response body for the input media URL.

func URLtoListenIPandPort
