: Greg, No I'm not running in 16bpp, but there is something else to this...
because there are 2 Segfaults. If I run with the --novideo option , I still get
the second segfault.
: But regardless... shouldn't it work also with 4bpp but slow!?
Usually the video bits are computed using YUV, and then blitted
using a specialized YUV->RGB blitter in SDL. If SDL doesn't have the
blitter, which I don't think it does for < 8bpp (dvdview requires >= 16),
then SDL will "parachute", which usually ends up in a segfault, I think
because of the multi-threaded nature of SMPEG.
:
: Do you have a time frame in the DVDview app release?
This will be included in the next mwin release. I will try to check
in most of the Microwindows changes in the next day or so.
Regards,
Greg
