[MPlayer-dev-eng] AC3 passthrough, about ac3 stream bitspersample.

[Wei Jiang]

Hi, 

I am a developer for XBMP, thanks to great work of
mplayer team, we have a very powerful media engine in
XBOX.

My issues is when I testing AC3 passthrough codec
hwac3, I find the bitspersample actaully retuen a
value of 8. 

As current hwac3 codec does is wrap the AC3 stream in
16 bits PCM package, this value should be 16.

The problem for this 8 bps return is it caused wrong
initial audio delay calculation.
(Audio Buffer)/output_bps.

The code is in libao2, afmt.c, I just quto the lines
that are concerned.

	case AFMT_MPEG:
	case AFMT_AC3:
	default:
	    return 8;//default 1 byte
	
Monkeyhappy.
