Date: Mon, 27 Oct 1997 03:02:30 +0100 (MET) From: Eivind Eklund <eivind@bitbox.follo.net> To: multimedia@freebsd.org Subject: Bt848 driver patches Message-ID: <199710270202.DAA00345@bitbox.follo.net>
next in thread | raw e-mail | index | archive | help
The following patches add PAL support, and make some more of the code
table-driven than before. Beware that I don't know the correct magic
for RSVD - heck, I don't even know what it means :-)
I still don't get sound, and haven't looked at the 32-bits color issue
yet - I'll look at those issues as soon as these patches (or similar)
have been OKed.
Could somebody test that it still work OK with NTSC? Should I commit
it if it work OK?
Eivind.
