[MPlayer-dev-eng] [PATCH] ad_hwac3.c patch for cmpci sound card

[C.L. Tien - 田承禮]

Hi,

I tested MPlayer with my cmpci driver on Mac G4, and found the reason why it cannot use -ac hwac3 to send AC3 data. The AC3 data need the same processing as for little-endian system because AC3 data is independent on byte-order.

The attach patch is necessary for cmpci to send AC3 data through the S/PDIF output.

I also found that MPlayer cannot send multichannel PCM with PowerPC because it insisted on sending AFMT_S16_BE, while our hardware only support AFMT_S16_LE, pitty.

And the description in mplayer.1 about -output is wrong -- it doesn't match the format defined in afmt.h

Sincerely,
ChenLi Tien
