[MPlayer-users] error compiling: libao2: missing AFMT_U* defines

[Walter Haidinger]

Hi!

I'm unable to compile MPlayer-1.0pre6 and the most recent CVS version 
unter SuSE 9.1 with vanilla 2.6.10 kernel and commercial OSS 3.99.1i 
drivers.

The OSS developers think it is a mplayer bug. 
I've appended their reply below.

Here's the output of the failed compilation.

Previous mplayer 1.0pre5 version did _not_ have the AFMT_U* defines.

Any hints howto solve this?

PPS: Here's the response of the OSS developers regarding the bug.
     Hope that helps too!

Hi,

This is definitely a bug in mplayer.

The only unsigned format being used by any hardware is AFMT_U8. The 16 and
24 bit formats supported by the sound cards are always signed ones. So
trying to use formats like AFMT_U32_LE doesn't make any sense.

I don't know where the authors of mplayer have found formats like
AFMT_U32_LE but they don't exist in OSS and they will not be added to it
in the future.

Best regards,
