• how to stop the FFmpeg process programmatically without using Ctrl + C ?

  30 septembre 2024, par bee

  const shell = require("shelljs");

const processShell = shell.exec(
  `ffmpeg -i "https://pull-hls-f16-va01.tiktokcdn.com/game/stream-2998228870023348312_or4/index.m3u8?expire=1728629296&session_id=000-2024092706481532076B1319E1100113F8&sign=1016b521d08053bc0ae8eddb0881b029" -movflags use_metadata_tags -map_metadata 0 -metadata title="Chill chill kiß║┐m k├¿o Warthunder" -metadata artist="bacgaucam" -metadata year="2024" -c copy "downloads/bacgaucam-927202491939.mp4" -n -stats -hide_banner -loglevel error`,
  { async: true }
);

setTimeout(() => {
  // processShell.kill();
  process.exit();
}, 20000);


  


  my video only works when I use Ctrl+C to stop it. I’ve tried using process.exit(), .kill(pid, "SIGINT"), and the .kill() method from the shell.exec() ffmpeg() of fluent-ffmpeg or spawn() of child_process reference, but none of them work

  


  If you want to test it directly, please message me to get a new live url in case it expires (https://t.me/ppnam15) or clone this :

  can anyone help ? Thanks !

  


• How to extract the first frame from a video ?

  10 août 2024, par Andrew

  I am trying to extract the first frame from a video to save it as a preview.

  


  Here's an almost working solution using ffmpeg :

  


  func extractFirstFrame(videoBytes []byte) ([]byte, error) {
    input := bytes.NewReader(videoBytes)

    var output bytes.Buffer

    err := ffmpeg.Input("pipe:0").
        Filter("select", ffmpeg.Args{"gte(n,1)"}).
        Output(
            "pipe:1",
            ffmpeg.KwArgs{
                "vframes": 1,
                "format":  "image2",
                "vcodec":  "mjpeg",
            }).
        WithInput(input).
        WithOutput(&output).
        Run()

    if err != nil {
        return nil, fmt.Errorf("error extracting frame: %v", err)
    }

    return output.Bytes(), nil
}


  


  The problem with this is that it can only process horizontal videos. For some reason it will throw a 0xbebbb1b7 error for a vertical videos. I don't understand why is that, probably because this is my very first time with ffmpeg.

  


  Also, I am concerned if this solution is optimal. My assumption is that the whole video will be loaded into the memory first, which is kinda bad and I would like to avoid that

  


  I use https://github.com/u2takey/ffmpeg-go, but errors are the same even if I run it using exec :

  


      cmd := exec.Command(
        "ffmpeg",
        "-i", "pipe:0",
        "-vf", "select=eq(n\\,0)",
        "-q:v", "3",
        "-f", "image2",
        "pipe:1",
    )


  


  Interestingly enough, I noticed that running command in the terminal will work as expected with any type of video ffmpeg -i .\video_2024-08-10_00-03-00.mp4 -vf "select=eq(n\,0)"  -q:v 3 output_image.jpg, so the problem may be on how I send those videos to my server. I useFiber and send videos as multipart/form-data and then read it like this :

  


      form_data, err := c.FormFile("image")
    file, err := form_data.Open()
    bytes, err := io.ReadAll(file)
    ....
    preview, err := extractFirstFrame(bytes)



  


  I also managed to find logs for the failed attempt :

  I also realized that the problem was not related to the video orientation, but to to the video from a specific source uploaded specifically on my server 🤡 Such a weird coincidence that I decided to test my video upload with those files, but anyway. And those are.... Downloaded instagram reels lol. But again, ffmpeg works just fine when ran in terminal
