• 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).

• How to set FFmpeg overly text opacity / transparent ?

  28 novembre 2022, par ujjally

  I want to add overly text into video with custom opacity or transparent like 50% 80%

  


  ffmpeg -i video.mp4 -vf drawtext="fontfile='C\:/Users/BRIGHT/AppData/Local/Microsoft/WINDOWS/fonts/RacingSansOne-Regular.ttf':text='YouTube.com':fontsize=h/15:fontcolor=yellow@0.5:bordercolor=white:borderw=1:y=(h-text_h*24):x=(mod(-0.5*n\,w+tw)-tw)" -codec:a copy output.mp4


  


• How do I redirect the output of SpeechSynthesizer to a Process of ffmpeg

  27 septembre 2020, par TheOneAndOnlyMrX

  I am trying to have a SpeechSynthesizer generate some audio data, pipe it into a Process of FFmpeg, and have FFmpeg save the data to a file (output.wav). Eventually, the audio data will be used for something else, which is why I am using FFmpeg.

  


  using (MemoryStream voiceStream = new MemoryStream())
        using (Process ffmpeg = new Process())
        {
            SpeechSynthesizer synth = new SpeechSynthesizer();

            int samplesPerSecond = 48000;
            int bitsPerSample = 8;
            int channelCount = 2;
            int averageBytesPerSecond = samplesPerSecond * (bitsPerSample / 8) * channelCount;
            int blockalign = (bitsPerSample / 8) * channelCount;
            byte[] formatSpecificData = new byte[0];

            synth.SetOutputToAudioStream(
                voiceStream,
                new System.Speech.AudioFormat.SpeechAudioFormatInfo(
                    System.Speech.AudioFormat.EncodingFormat.Pcm,
                    samplesPerSecond,
                    bitsPerSample,
                    channelCount,
                    averageBytesPerSecond,
                    blockalign,
                    formatSpecificData
                    )
                );

            synth.Speak("Hello there");

            synth.SetOutputToNull();

            ffmpeg.StartInfo = new ProcessStartInfo
            {
                FileName = "ffmpeg",
                Arguments = $"-y -f u8 -ac 2 -ar 48000 -i pipe:0 out.wav",
                UseShellExecute = false,
                RedirectStandardOutput = true,
                RedirectStandardInput = true
            };

            ffmpeg.Start();

            using (Stream ffmpegIn = ffmpeg.StandardInput.BaseStream)
            {
                voiceStream.CopyTo(ffmpegIn);
                
                ffmpegIn.FlushAsync();
            }
        }


  


  When running the program, FFmpeg said that the input stream contains no data, and returns an empty file.
I believe that I do not interface properly with the Process object, however, the problem might also be my incorrect specification of the audio stream, since I do not know much about audio.
