Make sure you're using the 1.0-2960 drivers from nvidia, and the original line
in XJ.cpp. The previous nvidia drivers had I420 video (the format it's using
internally) flipped with YV12.

Basically, you're seeing blue because the two color fields are swapped.

If it still doesn't work, do this:

Replace line 746 (848 in current cvs) of NuppelVideoPlayer.cpp (the memcpy)
with this:

memcpy(X11videobuf, vbuffer[rpos], video_width * video_height);
memcpy(X11videobuf + video_width * video_height, vbuffer[rpos] +
video_width * video_height * 5 / 4, video_width *
video_height / 4);
memcpy(X11videobuf + video_width * video_height * 5 / 4,
vbuffer[rpos] + video_width * video_height, video_width *
video_height / 4);

That _will_ fix it, as it swaps the two color fields in memory before the
buffer's sent to the video card for output. It'll revert back to funky
colors when it's paused, but the fix for that is similar.

I think I shall add a 'PeopleAreBlue' setting to the config file (it'll
basically just do that memcpy change)..

Oh, and if you upgrade CVS, check out the new 'Codec' setting in the config
file. Might as well use some more of that P4, no? =)

That solved it. I was acutally using a more recent driver (lower version
number, but later release date). This is *much* better.

Am thinking about the following mythTV related projects (I'll start working
on one of them over the weekend):

- a mythImage system to read/display digital photos
- a burning system to move video onto VCD/SVCD(/DVD?)
- also burning from playlist(s) onto music CDs and mp3 CDs
- LCD display module (use remote without tv on to play music, for example)
- second tuner card support (watch one, record other and/or record 2)

If anyone has any thoughts on these, please let me know.

BR,

Thor

Yay! That would rock.

And maybe even picture in picture?!?! This would also
be VERY cool.

I think I better get busy and build my Mythbox so I
can start messing with this stuff. :)

There's been a newer release?

I've gotten 3 or 4 requests for that, I think...

Probably one of the most requested features, and the one of the ones I'm least
interested in writing =)

I've been planning on working on the multiple tuner stuff for awhile..
Already have a second card sitting here doing nothing. So unless you
_really_ want to, I probably will get to it soonish. I've got things sorta
half setup for it already.

Hi.. Been lurking here since people mentioned this project on slashdot
:) I've been planing on building a pvr/multimedia server for some time.
Just want to say an lcd or led display would be really neat IMHO.

OK, I'll try and focus on that.

If you're already deep into second tuner card work, makes much more sense
for me to focus on the burning stuff.
