Experimental 4-channel and 5.1-channel support in MediaCoder (Stanley posted on July 20th, 2007 )

Experimental 4-channel and 5.1-channel audio transcoding is added in MediaCoder Please note that multi-channel transcoding only works with audio encoders that supports them. Currently following audio encoders in MediaCoder can support multi-channel.

  • Nero Encoder
  • FAAC
  • Vorbis
  • FLAC
  • Waveform/PCM

To the multi-channel transcoding work as expected, you need to:

  • Make sure that your source file has at least a multi-channel audio track
  • If the source file has more than one audio track, choose an audio ID (on the Audio tab) that represents the audio track containing multi-channe audio (usually the first track is stereo and the second one is 5.1 for DVD)
  • Same on the Audio tab, set “Channel” to “4 Channels” or “5.1 Channels”.
  • Set a supported audio encoder

As it is still quite experimental, there are some other limits. A major limit is multi-audio transcoding still cannot be used when ripping a DVD, but it works with VOB files. So you can use freeware like DVD decrypter to dump the VOB file to your hard disk and then transcode it.

    I’m brazilian too, and I’ll try to translate Luiz’s message – with some changes to made more clear.

    “I install the full MediaCoder in my PC to open my mobile phone videos, but just the video works, without sound. I don’t understand english then I don’t know what change to made works fine. Wait informations. Luiz”

    Luiz, from and to how format are you trying to convert? I suppose that the mobile video is 3gp, then try to convert do Xvid for example (and in audio tab just check ‘copy audio’)

    Now in portuguese:
    Luiz, de qual e para qual formato você está tentando converter? Eu imagino que o formato do video do celular seja 3gp, então tente converter para vídeo formato Xvid (format) e Default (Container). Na aba audio, clique para marcar a opção ‘copy audio’

    Good luck,
    Boa sorte

    Please…some help!

    To Transcode the avi file into mpeg:
    left window:
    Audio tab:
    – Source: MEncoder
    – Encoder: Lame MP3
    rest remains as default
    Video tab:
    – Format and Container: MPEG1
    – Source and Backend: MEncoder
    Subtitle tab: Subtitle select the file srt in same directory of the avi file

    right window: default of software
