func CreateArgs ¶
func Transcode ¶
func Transcode(ctx context.Context, source, destination string, tOptions TranscodeOptions) ( progress chan Progress, done chan error, )
Transcode is specifically created to transcode video files which require some sort of burnt subtitles. It'll check for available streams in our source and if it contains a subtitle stream, it'll burn the subtitles (hardsub) otherwise it'll leave it and assume that the video already contains hardsubs. NOTE: assumes you have 'ffmpeg' in your PATH environment variables
Types ¶
type Progress ¶
type Progress struct {
FramesProcessed string `json:"framesProcessed"`
CurrentTime string `json:"currentTime"`
CurrentBitrate string `json:"currentBitrate"`
Percentage float64 `json:"percantage"`
Speed float64 `json:"speed"`
Duration float64 `json:"duration"`
CurrentDuration float64 `json:"currentDuration"`
}
Progress defines a transcode progress.
type TranscodeOptions ¶
TranscodeOptions are options. InputOptions are options defined before the source. OutputOptions are options defined after the video filters as mappings.
