  On supprime donc le double systeme de zoom URL + JS en laissant uniquement le zoom JS : par defaut le graphe jour est zoome sur les 90 derniers jours, mais il suffit de double-clicker pour avoir tout l’historique, que l’on peut zoomer/dezoomer par selection a la souris dans le graphe

• How do I make audio work with pulseaudio in systemd ? [migrated]

  1er avril 2022, par user5827693

  I'm trying to live stream my website to the rtmp server via pulseaudio, ffmpeg and chromium in ubuntu 20.04. Everything works great if I execute the following commands in shell :

  


  pulseaudio&
ffmpeg -y -f x11grab -draw_mouse 0 -s 1280x720 -i :1.0+0,0 -f pulse -ac 2 -i default -c:v libx264 -c:a aac -b:a 128k -f flv MY_SERVER &> /dev/null < /dev/null &
DISPLAY=:1.0 chromium-browser --autoplay-policy=no-user-gesture-required --disable-gpu --user-data-dir=/tmp/test --window-position=0,0 --window-size=1280,720 --app=MY_URL &


  


  However if I try to setup the same logic via systemd - everything works fine, except there is no audio. Below are my systemd files.

  


  pulseaudio.service

  


  [Unit]
Description=PulseAudio system server

[Service]
User=ubuntu
Type=notify
ExecStart=/usr/bin/pulseaudio --daemonize=no
Restart=always

[Install]
WantedBy=multi-user.target


  


  chromium.service

  


  [Unit]
Description=start chromium browser
After=pulseaudio.service

[Service]
User=ubuntu
Type=simple
Environment=DISPLAY=:1.0
ExecStart=/usr/bin/chromium-browser --autoplay-policy=no-user-gesture-required --disable-gpu --user-data-dir=/tmp/test --window-position=0,0 --window-size=1280,720 --app=MY_URL
Restart=always

[Install]
WantedBy=multi-user.target


  


  ffmpeg.service

  


  [Unit]
Description=start ffmpeg
Requires=display.service pulseaudio.service
After=pulseaudio.service

[Service]
User=ubuntu
Type=simple
ExecStart=/usr/bin/ffmpeg -y -f x11grab -draw_mouse 0 -s 1280x720 -i :1.0+0,0 -f pulse -ac 2 -i default -c:v libx264 -c:a aac -b:a 128k -f flv MY_SERVER
Restart=always

[Install]
WantedBy=multi-user.target


  


  I do not see any errors in my syslog regarding the audio. I can't figure out why it would work from shell but not from systemd.

  


  I tried the following :

  


  

  • Ran pulseaudio systemwide

  


  • Tried to setup systemd under root user

  


  • Tried to setup systemd under non root user

  


  • Tried all possible pulseaudio params

  I am trying to make a module for react-native that will change a video into a gif. I have little to no experience with android studios/java, but I would love to learn more ! I am using this library to convert the video to a gif. Here is my code :

  package com.reactlibrary;
  
  
  
  import android.widget.Toast;
  
  import com.facebook.react.bridge.ReactApplicationContext;
  
  import com.facebook.react.bridge.ReactContextBaseJavaModule;
  
  import com.facebook.react.bridge.ReactMethod;
  
  import com.github.hiteshsondhi88.libffmpeg.FFmpeg;
  
  
  
  public class RNGifMakerModule extends ReactContextBaseJavaModule {
  
  
  
    private final ReactApplicationContext reactContext;
  
  
  
    public RNGifMakerModule(ReactApplicationContext reactContext) {
  
      super(reactContext);
  
      this.reactContext = reactContext;
  
    }
  
  
  
    @Override
  
    public String getName() {
  
      return "RNGifMakerModule";
  
    }
  
  
  
    @ReactMethod
  
    public void alert(String message) {
  
        Toast.makeText(getReactApplicationContext(), "Error", Toast.LENGTH_LONG).show();
  
        String[] cmd = {"-i"
  
                , message
  
                , "Image.gif"};
  
        conversion(cmd);
  
    }
  
  
  
    public void conversion(String[] cmd) {
  
  
  
      FFmpeg ffmpeg = FFmpeg.getInstance(this.reactContext);
  
  
  
      try {
  
  
  
  
  
        // to execute "ffmpeg -version" command you just need to pass "-version"
  
        ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
  
  
  
          @Override
  
          public void onStart() {
  
          }
  
  
  
          @Override
  
          public void onProgress(String message) {
  
          }
  
  
  
          @Override
  
          public void onFailure(String message) {
  
          }
  
  
  
          @Override
  
          public void onSuccess(String message) {
  
          }
  
  
  
          @Override
  
          public void onFinish() {
  
          }
  
        });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
        // Handle if FFmpeg is already running
  
        e.printStackTrace();
  
      }
  
    }
  
  }

  And I get this error :

  Error:(43, 31) error: cannot find symbol class ExecuteBinaryResponseHandler

  This seems odd to be, because in the documentation for ffmpeg-android-java it says to use almost exactly the same code.

  Bounty

  The bounty will be awarded to you if you can find a way to convert a video.mp4 into a gif. You do not necessarily have to use FFmpeg, but your solution has to work with java/android studios.
