[MPlayer-dev-eng] [PATCH] endian fixes for ASF streaming

[Guillaume Morin]

Hi,

Here is a patch which adds some support for big endian archs. Since I
tried this on a WMV2 stream, I could not do extensive testing. But,
before Mplayer complains about the lack of codecs, data looked similar
to what I got with an x86 box.

Please apply.
