• FFMPEG Compilation and Video Thumbnail Issues [on hold]

  2 janvier 2016, par P. Paul

  I have compiled FFMPEg on a Linux, Centos machine according to the guide in here https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu , and the auto video thumbnail creation command in here https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video

  The problems are...

  1- When I use ffmpeg or ffmpeg -version command to check if ffmpeg has been installed I get the error message, "Command not found". But when I check for ffmpeg directory "~/ffmpeg_sources" is found and the machine says, "is a directory".

  2- Also, I did a test and upload video to the site to see if the video’s thumbnail will be automatically generated, but it didn’t show any thumbnail.

  Any help would be greatly appreciated.

  Thanks in advance !

• closing goroutine spawned by fiber endpoint

  30 mai 2023, par Nitin

  I have a program that is rtsp cameras to hls format using ffmpeg for streaming.
creating goroutines for each rtsp link as ffmpeg runs in background

  


  Streams are added by following code.

  


  func StreamProcess(data <-chan StreamData, ctx context.Context) {
for v := range data {
    ctx, _ := context.WithCancel(ctx)
    go func() {
        if !getStreams(v.camera_id) {
            var stream StreamState
            stream.camera_id = v.camera_id
            stream.state = true
            go Stream(v, ctx)
            wg.Wait()
        } else {
            return
        }
    }()
}   


  


  }

  


  Streaming function which runs ffmpeg command.

  


  func Stream(meta StreamData, ctx context.Context) error {
    log.Println("Started Streaming")
    ffmpegCmd := exec.Command("ffmpeg", "-i", meta.rtsp, "-pix_fmt", "yuv420p", "-c:v", "libx264", "-preset", "ultrafast", "-b:v", "600k", "-c:a", "aac", "-b:a", "160k", "-f", "rtsp", fmt.Sprintf("rtsp://localhost:8554/%s", meta.camera_id))
    output, _ := ffmpegCmd.CombinedOutput()

    log.Println(string(output))

    for {
        select {
        case <-ctx.Done():
           log.Println("killing process")
           ffmpegCmd.Process.Kill()
           return nil
        }
    }}


  


  my Goal is to stop each os.exec process (ffmpeg command) or at least close all goroutines that are under ffmpeg commands without closing fiber server.
