  here is my code,

  package video_audio_text.project;
  
  
  
  import javax.sound.sampled.AudioFileFormat.Type;
  
  import com.sun.speech.freetts.FreeTTS;
  
  import com.sun.speech.freetts.Voice;
  
  import com.sun.speech.freetts.VoiceManager;
  
  import com.sun.speech.freetts.audio.AudioPlayer;
  
  import com.sun.speech.freetts.audio.SingleFileAudioPlayer;
  
  
  
  public class AudioToText {
  
  
  
      /**
  
       * Example of how to list all the known voices.
  
       */
  
  
  
  
  
      public static void main(String[] args) {
  
  
  
         // listAllVoices();
  
          System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
  
  
  
          FreeTTS freetts;
  
          AudioPlayer audioPlayer = null;
  
          String voiceName = "kevin16";
  
  
  
          System.out.println();
  
          System.out.println("Using voice: " + voiceName);
  
  
  
          /* The VoiceManager manages all the voices for FreeTTS.
  
           */
  
          VoiceManager voiceManager = VoiceManager.getInstance();
  
          Voice helloVoice = voiceManager.getVoice(voiceName);
  
  
  
          if (helloVoice == null) {
  
              System.err.println(
  
                  "Cannot find a voice named "
  
                  + voiceName + ".  Please specify a different voice.");
  
              System.exit(1);
  
          }
  
  
  
          /* Allocates the resources for the voice.
  
           */
  
          helloVoice.allocate();
  
  
  
          /* Synthesize speech.
  
           */
  
  //create a audioplayer to dump the output file
  
         audioPlayer = new SingleFileAudioPlayer("/Users/user/Documents/test",Type.WAVE);
  
  //attach the audioplayer 
  
         helloVoice.setAudioPlayer(audioPlayer);
  
  
  
  
  
          helloVoice.speak("Thank you for giving me a voice. "
  
                           + "I'm so glad to say hello to this world." + 
  
                          + "here you go good way");
  
  
  
  
  
  
  
          /* Clean up and leave.
  
           */
  
          helloVoice.deallocate();
  
          audioPlayer.close();
  
          System.exit(0);
  
      }
  
  
  
  }

  But i need to give the audio file and extract text from the audio file.

  However I am continuously getting the followng error :

  



  RuntimeError: No ffmpeg exe could be found. Install ffmpeg on your system, or set the IMAGEIO_FFMPEG_EXE environment variable.


  



  I have installed ffmpeg in my system and have added it in path. Also in cmd,

• How to do reprocessing H264 data to image/video

  3 octobre 2017, par somethingunexpected

  I have been working on a project which blows my mind.

  First of all, I have an IP camera that streams H264 data. I am able to stream it with its RTSP url via VLC/ffmpeg/python (rtsp ://ip:port/PSIA/Streaming/channels/2 ?videoCodecType=H.264). So, there is nothing to worry about streaming.

  However, on the project, camera is connected to the another system. This system gives the H264 data via ethernet to my PC, so camera is not connected directly to the PC.
  The system gives the data in every 10 ms at 1000 bytes. For example, if incoming data is 800 bytes, it adds 200 null bytes.

  What I can do is to extract these null bytes and take the raw data via a socket. For latency, I use thread module so there is no data leakage.

  What I gotta do is to turn these raw H264 data to an image sequence or a video that can be displayed via VLC, ffmpeg, Classic Media Player etc.

  I preferrebly want to write my code in Python and every operation has to be in real-time. So, any help would be appreciated.
