Capture video footage from RTSP IP cameras.
Provides a simple interface to set FFMPEG options and capture video from an RTSP source.
Lots of other libraries out there do ffmpeg and rtsp things, but I couldn't find any that fit this simple task of "get a video snippet from a camera."
package main
import (
"log"
"golift.io/ffmpeg"

func main() {
/*
* Example non-transcode direct-save from securityspy.
*/
securitypsy := "rtsp://user:[email protected]:8000/++stream?cameraNum=1"
output := "/tmp/securitypsy_captured_file.mov"
c := &ffmpeg.Config{
FFMPEG: "/usr/local/bin/ffmpeg",
Copy: true, // do not transcode
Audio: true, // retain audio stream
Time: 10, // 10 seconds
}
encode := ffmpeg.Get(c)
cmd, out, err := encode.SaveVideo(securitypsy, output, "SecuritySpyVideoTitle")
log.Println("Command Used:", cmd)
log.Println("Command Output:", out)
if err != nil {
log.Fatalln(err)
}
log.Println("Saved file from", securitypsy, "to", output)
/*
* Example transcode from a Dahua IP camera.

dahua := "rtsp://admin:[email protected]/live"
output = "/tmp/dahua_captured_file.m4v"
f := ffmpeg.Get(&ffmpeg.Config{
Audio: true, // retain audio stream
Time: 10, // 10 seconds

cmd, out, err = f.SaveVideo(dahua, output, "DahuaVideoTitle")
log.Println("Command Used:", cmd)
log.Println("Command Output:", out)
if err != nil {

log.Println("Saved file from", dahua, "to", output)
