[vlc] #Transcode - mpga (a52->mpga) 6 channels to 2 Channels transcoding

[Simon]

Many thanks for fixing AC3 to mpga transcoding problem I reported earlier
(CVS version). It now defaults to 2 channels (stereo) which is even better
(see my original email below).

However, this is causing problems in a number of DVDs I have. I hear perfect
background music, but some of the conversation channels are barely audible.
I presume the transcoding route picks up 2 predefined  channels. Ideally,
all 6 channels should be mixed into 2 channels. Alternatively, is there a
way of selecting which 2 audio channels get copied to mpga format?

Best regards
Simon

Make sure you specify a stereo outut stream as the mpga encoder won't deal

Using "--sout=#transcode{acodec=mpga,ab=192,channels=2}:blabla" for
instance.

Hope this helps,
