• How do I install FFmpeg for my bot to play music ?

  28 juin 2023, par Shiqi Wang

  I followed a Youtube Tortual on how to make a music bot, and every piece of code made sense, there is just one problem. I thought I installed FFmpeg which is the thingy which makes the bot play audio I believe, the way I installed it was running the following command : pip install ffmpeg

  


  So I waited it to finish up, and attempted to play music, and here is the error message

  


  Traceback (most recent call last):

• Compressed mp4 video is taking too long time to play in Android(exo player)

  4 mai 2018, par User

  Video(mp4) is recorded from android camera and sent to backend, here I am using ffmpeg wrapper to compress the video[44mb video to 5.76mb]. compression is working well, But when I send the video for play in android(exo player), is taking too long time to start.

  below is my code to compress :

   FFmpegBuilder builder = new FFmpegBuilder()
  
                     .setInput("D:/dummyVideos/myvideo.mp4")     // Filename, or a FFmpegProbeResult
  
                     .overrideOutputFiles(true) // Override the output if it exists
  
                     .addOutput("D:/dummyVideos/myvideo_ffmpeg.mp4")   // Filename for the destination
  
                     .setFormat("mp4")       // Format is inferred from filename, or can be set
  
                     .disableSubtitle()       // No subtiles
  
                     .setAudioChannels(1)         // Mono audio
  
                     .setAudioCodec("aac")       // using the aac codec
  
                     .setAudioSampleRate(48_000) // at 48KHz
  
                     .setAudioBitRate(32768)     // at 32 kbit/s
  
                     .setVideoCodec("libx264")     // Video using x264
  
                     .setVideoFrameRate(24, 1)     // at 24 frames per second 
  
                     .setVideoResolution(1280, 720) // at 640x480 resolution
  
                     .setVideoBitRate(762800)
  
                     .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
  
                     .done();

  Can anyone tell me why video is taking too long time to play in exo player ? Is anything wrong in the compression ?
