I thought I should ask the obvious question before delving into details
- has anybody tried this configuration:
Gentoo Linux
mplayer (1.0pre5 - not the latest but I have other issues with later
versions.)
amd64
DirectFB-0.9.24
Matrox G450
I'm using the dfbmga output driver in mplayer.
This setup *does* work with DirectFB-0.9.22 - simply upgrading to
DirectFB-0.9.24 seems to cause a problem. Changing back to
DirectFB-0.9.22 fixes it again...
This same configuration (with 0.9.24) *does* work on a 32-bit Pentium3
machine (still Gentoo, mplayer 1.0pre5, Matrox G450 etc.)
I tried running the failing version within gdb, and get this:

...So this looks like possibly something bad happened in maven_init().
Is this enough to give someone a clue?
I will happily do some more investigation if someone would be kind
enough to suggest some things for me to have a look at. It would be good
to get this working on the amd64 platform as I am writing some stuff
myself using DirectFB and want to be using the more recent (0.9.24)
implementation.
Meanwhile I'm stuck at 0.9.22...
I didn't try 0.9.23 as it didn't exist long enough for the Gentoo guys
to make an ebuild for it. In fact I raised the bug to get the ebuild for
0.9.23 and by the time I sent it there was 0.9.24... ;)
Regards,
James.
