• MobileFFMPEG Output file #0 does not contain any stream

  30 septembre 2020, par Alhaj

  I am using implementation 'com.arthenica:mobile-ffmpeg-full:4.4'

  


  I just want o crop audio file to 10 second to 20 second

  


  '''
fun cropAudio(input :String)

  


      val newFileName = UUID.randomUUID().toString()

    val location: String = getBatchDirectoryName()!!

    val output: String = location + "/" + newFileName + ".mp3"

    val temp=" -i $input -ss 60 -to 70 $output"

    Log.e("alhaj", " a $s")

    FFmpeg.execute(temp, object : ExecuteCallback {

        fun onSuccess(message: String?) {
            uploadOnFirebase(output, title)
            mediaPlayer.stop()
            Log.e("alhaj", message!!)
        }

        override fun apply(executionId: kotlin.Long, returnCode: Int) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                Log.i("alhaj", "Async command execution completed successfully.");
            } else if (returnCode == RETURN_CODE_CANCEL) {
                Log.i("alhaj", "Async command execution cancelled by user.");
            } else {
                Log.i("alhaj", String.format("Async command execution failed with rc=%d.", returnCode));
            }
        }
    }.toString())
}

• avfilter/f_ebur128 : add all sample rates support

  4 mars 2021, par Paul B Mahol

  avfilter/f_ebur128 : add all sample rates support
  The magic constants come from the unofficial "ITU-R BS.1770-1 filter
  
  specifications"¹ by Raiden (libebur128) which relies on "Parameter
  
  Quantization in Direct-Form Recursive Audio Filters"² by Brian
  
  Neunaber.
  The constants seem to include a quantization bias, for example :
  
   Vb is supposed to be exactly √Vh in a high shelf filter
  
   the Pre-filter Gain should likely be 4dB
  
   Pre Q and RLB Q are respectively very close to √½ and ½
  Those are not adjusted to prevent the values from drifting away from
  
  the official specifications.
  An alternative to this approach would be to requantize on the fly as
  
  proposed by pbelkner³, where the 48kHz code path would use the exact
  
  specifications constants while derivating constants for other
  
  frequencies.

  Le pb vient du fait que c’est le forum id_thread qui est enregistré dans la table spip_resultats.
