how to stop the FFmpeg process programmatically without using Ctrl + C ?
30 septembre 2024, par beeconst 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 kiếm kèo Warthunder" -metadata artist="bacgaucam" -metadata year="2024" -c copy "downloads/bacgaucam-927202491939.mp4" -n -stats -hide_banner -loglevel error`,

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 theshell.exec()
ffmpeg()
of fluent-ffmpeg orspawn()
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 AndrewI 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 usingexec
:

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 asmultipart/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
