  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • FFmpeg stdout emits more frames than it should

    29 décembre 2022, par distante

    I am running this command to get two images per second from an rtsp stream :

    


    const ffmpeg = spawn(this.ffmpeg, [
      // Set the frame rate of the input video to 2 frames per second
      '-r',
      '2',
      // Specify that the RTSP stream should use TCP as the transport protocol
      '-rtsp_transport',
      'tcp',
      // Set the input source to the RTSP stream specified by the `rtspUrl` variable
      '-i',
      rtspUrl,
      // Set the video filter to only output two frames per second (final video)
      '-vf',
      'fps=2',
      // Set the output format to "image2pipe," which specifies that the output should be written to stdout as a series of images in a pipe
      '-f',
      'image2pipe',
      // Overwrite any existing output file without prompting for confirmation
      '-y',
      // Set the output destination to stdout
      '-',
    ]);



    


    I am subscribing to the stdout and saving each emit into a file (just for testing, I need to process the data later)

    


        let i = 0;
    from(ffmpeg.stdout)
      .pipe(
        concatMap((data) => {
          i++
          return writeFile(`file_${i}`, data).then(() => i);
        }),
      )
      .subscribe((i) => {
        this.imageLogger.log(`file_${i} saved`);
      });


    


    The thing is, I am getting a lot more than 2 images per second :

    Edit 2 :

    


    When I run this command on the terminal :

    


    ffmpeg -r 2 -rtsp_transport tcp -i "rtsp://user:password@192.68.45.54:554/stream2" -vf fps=2 -timecode 00:00:00:00 test.mp4


    


    The generated video has a frame rate of 2 but it looks like it is in slow motion. Since the source video has also a timer, I see how it takes something like 12 "frames" to go from one second to another.

    


    This is the output :

    Trying to publishlive streaming video via incoming live stream via rtmp.But the video's pixel get breakdown when played live.Error generates non monotonically increasing dts to muxer in stream. I am using xuggler api.
