# FFMPEG

A simple package for using FFMPEG

## Open a video file

```go

package mypackage

import (

	"ffmpeg"

	"fmt"

)

func MyMovie() {

	movie := ffmpeg.Movie{}

	var path string = "/Users/leon/Downloads/4.mp4"

	err := movie.Initialize(&path)

	if err != nil {

		fmt.Println(err)

	} else {

		fmt.Println(movie)

	}

}

```

## Transcode a video file

```go

package mypackage

import (

	"ffmpeg"

	"fmt"

	"path/filepath"

)

func MyTranscoder() {

	path_str, _ := filepath.Abs("movies/awesome_widescreen.mov")

	movie := ffmpeg.Movie{}

	movie.Initialize(&path_str)

	out_path_str, _ := filepath.Abs("movies/output/awesome_widescreen.mp4")

	transcoder := ffmpeg.Transcoder{Movie: movie, OutputFile: out_path_str, RawOption: ffmpeg.EncodingOption{VideoCodec: "h264"}}

	transcoder.Run()

	fmt.Println(transcoder.Movie)

}

```

## Append a video file to another

```go

package mypackage

import (

	"ffmpeg"

	"fmt"

	"path/filepath"

)

func MyAppend() {

	path_str, _ := filepath.Abs("movies/1.mp4")

	advert_path_str, _ := filepath.Abs("movies/awesome_widescreen.mov")

	movie := ffmpeg.Movie{}

	movie.Initialize(&path_str)

	out_path_str, _ := filepath.Abs("movies/output/awesome_widescreen_1.mp4")

	transcoder := ffmpeg.Transcoder{}

	transcoder.Initialize(&movie, &out_path_str, &ffmpeg.EncodingOption{VideoCodec: "h264", AppendMovie: advert_path_str}, &ffmpeg.TranscoderOption{})

	transcoder.Append()

}

```

## Prepend a video file to another

```go

package mypackage

import (

	"ffmpeg"

	"fmt"

	"path/filepath"

)

func MyPrepend() {

	path_str, _ := filepath.Abs("movies/1.mp4")

	advert_path_str, _ := filepath.Abs("movies/awesome_widescreen.mov")

	movie := ffmpeg.Movie{}

	movie.Initialize(&path_str)

	out_path_str, _ := filepath.Abs("movies/output/awesome_widescreen_2.mp4")

	transcoder := ffmpeg.Transcoder{}

	transcoder.Initialize(&movie, &out_path_str, &ffmpeg.EncodingOption{VideoCodec: "h264", AppendMovie: advert_path_str}, &ffmpeg.TranscoderOption{})

	transcoder.Prepend()

}

```
