How to transcode a media file

go get github.com/xfrr/goffmpeg

package main

import (
    "github.com/xfrr/goffmpeg/transcoder"
)

var inputPath = "/data/testmov"
var outputPath = "/data/testmp4.mp4"

func main() {

	// Create new instance of transcoder
    	trans := new(transcoder.Transcoder)

	// Initialize transcoder passing the input file path and output file path
    	err := trans.Initialize( inputPath, outputPath )
    	// Handle error...

	// Start transcoder process
	done := trans.Run()

	// This channel is used to wait for the process to end
	err = <-done
	// Handle error...

}

How to get the transcoding progress

...
func main() {

	// Create new instance of transcoder
    	trans := new(transcoder.Transcoder)

	// Initialize transcoder passing the input file path and output file path
    	err := trans.Initialize( inputPath, outputPath )
    	// Handle error...

	// Start transcoder process
	done := trans.Run()

	// Returns a channel to get the transcoding progress
	progress := trans.Output()

	// Example of printing transcoding progress
	for msg := range progress {
		fmt.Println(msg)
	}

	// This channel is used to wait for the transcoding process to end
	err = <-done

}

Progress properties

type Progress struct {
	FramesProcessed string
	CurrentTime     string
	CurrentBitrate  string
	Progress        float64
	Speed           string
}

Example

func main() {

	// Create new instance of transcoder
    	trans := new(transcoder.Transcoder)

	// Initialize transcoder passing the input file path and output file path
    	err := trans.Initialize( inputPath, outputPath )
    	// Handle error...

	// SET FRAME RATE TO MEDIAFILE
	trans.MediaFile().SetFrameRate(70)
	// SET ULTRAFAST PRESET TO MEDIAFILE
	trans.MediaFile().SetPreset("ultrafast")

	// Start transcoder process
	done := trans.Run()

	// Returns a channel to get the transcoding progress
	progress := trans.Output()

	// Example of printing transcoding progress
	for msg := range progress {
		fmt.Println(msg)
	}

	// This channel is used to wait for the transcoding process to end
	err = <-done

}
