FFmpeg

使用 FFmpeg 实现 视频转码、缩略图、获取时长

转码

转码为 h264 mp4 文件

app.yml

ffmpeg:
  ffmpeg: /opt/homebrew/bin/ffmpeg
  ffprobe: /opt/homebrew/bin/ffprobe
  command_timeout: 1h

main.go

package main

import (
	"github.com/langwan/langgo"
	"github.com/langwan/langgo/components/ffmpeg"
)

func main() {
	langgo.Run(&ffmpeg.Instance{})
	ffmpeg.Get().Transcoding("../../../samples/sample.mov", "./output.mp4", true)
}

生成缩略图

app.yml

ffmpeg:
  ffmpeg: /opt/homebrew/bin/ffmpeg
  ffprobe: /opt/homebrew/bin/ffprobe
  command_timeout: 1h

main.go

package main

import (
   "github.com/langwan/langgo"
   "github.com/langwan/langgo/components/ffmpeg"
   "time"
)

func main() {
   langgo.Run(&ffmpeg.Instance{})
   ffmpeg.Get().Thumbnail("../../../samples/sample.mov", "./output.jpg", time.Second, true)
}

获取视频时长

main.go

package main

import (
   "fmt"
   "github.com/langwan/langgo"
   "github.com/langwan/langgo/components/ffmpeg"
)

func main() {
   langgo.Run(&ffmpeg.Instance{})
   duration, err := ffmpeg.Get().Duration("../../../samples/sample.mov")
   if err != nil {
      return
   }
   fmt.Println(duration)
}

output

12.96s
