Re-encode 6-channel discrete audio to stereo

[MonkeyBites]

Hi,

I have a couple of HD movies (1080p) encoded with 6-channel discrete audio. When re-encoding them for my iPad, the only option available is AAC Stereo. The result movie file, though, is three times as long as expected. It obviously joins two of the six audio channels to create stereo sound, adding the remaining pairs of audio channels after the video track has ended.

On the other hand, my iPad plays SD movies with 6-channel discrete audio just fine. So my question really is: Is there a way to leave the 6-channel audio untouched when re-encoding a movie file (i.e. something like AAC Passthru)?

Thanks!

Use the nightly builds. Announcement is at the top of every forum. Support of multi-channel inputs such as yours was added after 0.9.4 was released.
