[MPlayer-dev-eng] [PATCH] biPlanes must always be 1 in avi files (bug #146)

[Reimar Döffinger]

Hi,
this patch makes sure that biPlanes is always 1 when writing an AVI, as
according to Microsoft that's how it must be (see bugzilla for more
information).
I intend to apply soon.

Greetings,
Reimar Döffinger
