Functions

func HMSMSToSeconds

func HMSMSToSeconds(hhmmssms string) float64

HMSMSToSeconds - converts timecode (H:M:S.MS) to seconds float64 (S.MS).

Types

type File

type File struct {
	Format  Format   `json:"format,omitempty"`
	Streams []Stream `json:"streams,omitempty"`
}

File represents the information about media file returned by FFprobe.

func Probe

func Probe(filePath string) (f *File, err error)

Probe returns media file information.

func (*File) StreamDuration

func (f *File) StreamDuration(i int) (d float64, err error)

StreamDuration return streams duration as float64, uses MKV tags if the default duration value is not found. Returns -1 on errors. Returns format duration and error if no stream duration was found. returns 0 and error if no stream or fromat duration were found.

func (*File) String

func (f *File) String() string

Print prints out the contents of the media file.
