• App crashes on Google TV when playing MP4 videos

  14 avril 2023, par fab

  I am having problems with an Android app that was developed for me. The issue occurs when playing MP4 videos ; the app plays them correctly, but at some point, the app crashes and exits. I have been reviewing errors using Android Studio, and the only error that appears is the following :

  One clarification is that the app is built with IONIC and Angular.

  


  The FFMPEG code that converts the video in golang is as follows :

  


  func ConvertVideoFile(inputFileName, outputFileName string) error { err := ffmpeg_go.Input(inputFileName). Filter("scale", ffmpeg_go.Args{"800:600"}). Output(outputFileName, ffmpeg_go.KwArgs{ "c:v": "libx264", "profile:v": "high", "level": "3.1", "pix_fmt": "yuv420p", "preset": "medium", "crf": "23", "b:v": "782k", "r": "25", "c:a": "aac", "b:a": "2k", "ar": "48000", "movflags": "+faststart", "max_muxing_queue_size": "1024", }, ). OverWriteOutput().ErrorToStdOut().Run() return err }

• Museum of Multimedia Software, Part 4

  20 août 2010, par Multimedia Mike — Software Museum

  This is the last part of the series, at least until some more multimedia software shows up at my favorite thrift shop or the other boneyards I scavenge.

  Miscellaneous Multimedia Programs
  This set includes the titles Matinee FMV Screensaver, MetaCreations Painter Classic, and Multimedia JumpStart. The second one is likely a creation program. I have no idea what the third one is, while the first title gives me chills just thinking about the implications.

  
  
  

  Miscellaneous Creativity Software
  Magic Theatre and Microsoft Home : Creative Writer. I think I loaded up the former once to find a very basic animation program. The latter isn’t necessarily multimedia-related but certainly classifies as creative software. It also reminds me of the ad I once spied in Entertainment Weekly magazine during the mid-1990s for a Microsoft music history CD-ROM. MS branched out into all kinds of niches.

  
  
  

  More Multimedia Creativity Software
  VideoCraft and U-Create Games & Animation. I wager these would be fun to play around with if I had the time.

  
  
  

  Showcase CD-ROMs
  "What Can You Make ? Showcase 7" from Macromedia and Microsoft Multimedia Pack 10.

  
  
  

  Basic Multimedia Software Discs
  As a multimedia nerd, these Apple QuickTime and Microsoft Video for Windows discs make me sentimental.

  
  
  

  Real Software Collection
  Grit your teeth and gaze upon CD-ROM distributions of Real’s software. There is a RealAudio disc back from when Real still called themselves Progressive Networks. "Everything you need to hear the web roar !"

  
  
  

  Clips
  And a few multimedia clip CD-ROMs, along with a disc that promises to test and tune your MPC setup.

  
  
  

  Wrap-Up
  I would be remiss if I neglected to mention a few more pieces of multimedia creation software in my collection. First, there’s the Barbie Storymaker. I actually gave that one a go, as you can tragically see from that link. Further, the Taco Bell fast food restaurant chain ran, as one of their many kids meal promotions, a series of 4 simple Comics Constructor CD-ROMs. I played briefly with it here and again during an exploration of XML data formats and the parsing thereof (which the software uses).

• Play audio files on a guild channel (Not working on Ubuntu Server)

  18 octobre 2018, par danielperales555

  I want to make a "soundboard" on my Discord Bot.

  The bot is currently running on Ubuntu Server 18.04 in a VPS Hosting.

  I installed ffmpeg via aptitude apt-get install ffmpeg, and the respective node modules on my project via npm : npm install ffmpeg-binaries --save and npm install node-opus --save

  I have this provisional code :

  //Command syntax: !play (sound)
  
  if (!args[0]) return message.channel.send('noCorrectSyntax'); //args is provided by module.run
  
  
  
  let sound = args[0];
  
  let isReady = true;
  
  
  
  if (isReady) {
  
      isReady = false;
  
      let voiceChannel = message.member.voiceChannel;
  
      if (!voiceChannel) return message.channel.send('noChannel');
  
  
  
      voiceChannel.join().then(connection =>{
  
          const dispatcher = connection.playFile(`../resources/audios/${sound}.mp3`);
  
          if (!dispatcher) return message.channel.send('soundNotFound');
  
  
  
          console.log(`Playing ${sound} on ${message.member.voiceChannel.name}`);
  
  
  
          dispatcher.on("end", end => {
  
              voiceChannel.leave();
  
              console.log(`Finished`);
  
          });
  
      }).catch(err => console.log(err));
  
      isReady = true;
  
  } else {
  
      return message.channel.send('botNotAvailable');
  
  }

  When my bot joins the voice room, it leaves instantly without playing the sound.

  Am I doing something wrong by installing the ffmpeg codec this way ? Is a problem with the VPS ?

  (I tried with a new bot, installing ffmpeg on windows and setting the environment variable path and it worked fine)

  EDIT :

  I listened for the "error" and "debug" events on the StreamDispatcher (as specified in https://discord.js.org/#/docs/main/stable/class/StreamDispatcher?scrollTo=e-error), but I don’t receive errors or debug info.

  When I listen for the "speaking" event, is showed on my console as false
