package main

import (
    "flag"
    "log"
)

var (
    srcFile = flag.String("file", "", "The path to the soruce video.")
    destDir = flag.String("dest", "", "The directory where the manifest and segments are stored.")
    segment = flag.String("segment", "1000", "Dash segment value")
)

func main() {
    flag.Parse()

    if *srcFile == "" || *destDir == "" {
        log.Fatalf("The --file and --dest flags must be provided.")
    }
    MPDGen(*srcFile, *destDir, *segment)
}
