• carrierwave-ffmpeg .weba audio convert to .mp3 or .mp4

  14 mai 2018, par nmadoug

  I use react-mic on the front-end of my React/Rails application to capture audio from the user. react-mic formats the audio blob as .weba. I’m trying to convert the .weba to .mp4 or .mp3 using carrierwave-ffmpeg . I can isolate the issue to my Rails uploader, which is as follows :

  require 'fog/aws'
  
  
  
  class UserResponseUploader < CarrierWave::Uploader::Base
  
    include CarrierWave::FFmpeg
  
  
  
    if Rails.env.test?
  
      storage :file
  
    else
  
      storage :fog
  
    end
  
  
  
    version :mp3 do
  
      puts `which ffmpeg`
  
      # binding.pry
  
      process encode: [:mp3, audio_codec: "a libmp3lame -qscale:a 2"]
  
      # process :encode_audio=> [:mp4, audio_codec: "aac",:custom => "-strict experimental -qscale:a 2"]
  
  
  
      def full_filename(for_file)
  
        super.chomp(File.extname(super)) + '.mp3'
  
      end
  
    end
  
  
  
    # Directory where uploaded files will be stored on file system or AWS
  
    def store_dir
  
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  
    end
  
  end

  ffmpeg is installed on my local PC and I can run the command on the terminal to get an audio file created

  ffmpeg -i audio.weba -codec:a libmp3lame -qscale:a 2 willwork.mp3

  My problem is when I try and run everything in my code, I get the following error message :

  NameError (undefined local variable or method `e' for #):

  I don’t know where it’s complaining. I have a feeling the encoding line is causing the problem and I don’t have it set up properly.

  Any ideas ?

• Looking for Javacpp FFMPEG CustomIO Example

  26 février 2017, par user1902291

  I am trying to get Custom IO working with JavaCPP FFMPEG. Has anyone succeeded at this ? Can you post your code ?

  Here is mine (Scala), which does not work. It compiles and runs, but does not seem to call my Read and Seek methods

  val readPtr = new Pointer()
  
  val seekPtr = new Pointer()
  
  val userDataPtr = new Pointer()
  
  val read = new Read_packet_Pointer_BytePointer_int(readPtr) {
  
    override def call(userDataPtr: Pointer, @Cast(Array("uint8_t*")) buf: BytePointer, buf_size: Int): Int = {
  
      super.call(userDataPtr, buf, buf_size)
  
    }
  
  }
  
  val seek = new Seek_Pointer_long_int(seekPtr) {
  
    @Cast(Array("int64_t")) override def call(userDataPtr: Pointer, @Cast(Array("int64_t")) offset: Long, whence: Int): Long = {
  
      super.call(userDataPtr, offset, whence)
  
    }
  
  }
  
  
  
  val bufferSize = 1024 * 1024
  
  val readBuffer = new BytePointer(bufferSize)
  
  
  
  val avioContext = avformat.avio_alloc_context(
  
    readBuffer,   // internal buffer
  
    bufferSize,   // and its size
  
    0,            // write flag (1=true,0=false)
  
    userDataPtr,  // user data, will be passed to our callback functions
  
    read,
  
    null,         // no writing
  
    seek
  
  )
  
  
  
  formatContext.pb(avioContext)
  
  formatContext.flags(formatContext.flags | avformat.AVFormatContext.AVFMT_FLAG_CUSTOM_IO)
  
  formatContext.iformat(avformat.av_find_input_format("mp4"))
  
  
  
  avformat.avformat_open_input(formatContext, null.asInstanceOf[String], null, null)
