[xine-devel] OSS multichannel sample order

[Eduard H. <ed...@ao...>]

Hi. Multichannel again :)

While playing surround content using XINE that the sample order
is not the same I expected.

For 5.1 playback I expect:
1. Front L
2. Front R
3. Rear L
4. Rear R
5. Center
6. LFE

As XINE now only provides 1-5, LFE is simply left out. But,
I do not get this order. I assume there is no standard for the
sample order.

My sample order has the advantage that every format only skips
the last channels, if they are not provided. So no reordering
has to be done in the soundcard driver.

Here are all possible formats which make sense for the SbLive 5.1:

5.1	5.0	4.0	2.0
===	===	===	===
Front L	Front L	Front L Front L
Front R Front R Front R Front R
Rear L	Rear L	Rear L
Rear R	Rear R	Rear R
Center	Center
LFE

So, what is the order which is used now and do you intend to provide
the order I need?
