FFMPEG wrapper written in GO which allows to obtain the progress.
How to transcode a media file
go get github.com/xfrr/goffmpeg
package main
import (
"github.com/carousell/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 without checking progress
done := trans.Run(false)
// 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 with progress checking
done := trans.Run(true)
// 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
}
type Progress struct {
FramesProcessed string
CurrentTime string
CurrentBitrate string
Progress float64
Speed string
}
Those options can be set before starting the transcoding.
