Experimental 4-channel and 5.1-channel audio transcoding is added in MediaCoder 0.6.0.3820. 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
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.
