its really not a big deal... only takes a min to rescan my library. I guess i didnt read the post that said not to do a make install... what do you do to install the binaries without using "make install"?

either way, everythings running good again..

Hmm, what's this about not using make install? I did it and it's working for me.

Also, what's the procedure for updating my copy of xbmc-vdpau?

Is this right: (?)

svn update
make clean
make -j2 (for my dual core processor)
make install

you forgot the ./configure and any arguments after the make clean. If you have build problems, i did, they usually are resolved with make distclean.

I use make install but I first set up a prefix.

Code:
./configure  --prefix=~/svnXBMC

This means I can keep the stable XBMC installed and use it if I have problems.

The only thing to be aware of is it does use ~/.xbmc for settings. This is good in that you share settings but problems like library changes can cause issues.

So wait, is the 8400GS that people are using the PCI version? I'm very, very interested in all this since my xbmc computer, hooked up to my projector, is unfortunately pretty ancient (1.2GHz Athlon), so PCI-E is out of the question. If there's a PCI card that can run VDPAU fast enough I'll be jumping for joy!

Nope, 8400GS that people mention is PCI-E (most of the time is asus silent version)
I am afraid with PCI only you are out of luck as far as vdpau support, however new nvidia drivers (180.35) seems to start supporting the whole variety of nvidia chipsets so I am probably wrong Smile

Not true. I am using an 8400GS PCI, purchased from newegg. See here:

perfect Smile thx a lot
I have at least two systems (friends....) with PCI only that will benefit from that
thx again

Does WMV work with this build? I've tried playing a VC1 WMV file and it crashes XBMC. Sad


- motd2k - 2009-03-01 11:22

The commit log answers that question. WMV/VC1 is fine (on 32-bit systems, there's a small driver issue on x86_64), however FFmpeg - and therefore XBMC - does not support WMA-Pro. If the video is encoded with WMA-Pro audio then the likelyhood is that you're out of luck.


- dbldown768 - 2009-03-01 19:22

that must be my problem. I have a some movies i originally encoded in i believe windows media 10, probably professional, it crashes. I know they worked on the old xbox but not linux. anyway, i guess this is something i can live without as everything i encode now is mkv.

Hi chaps. First off well done to all involved in this project. I can't wait to sell my NMT and get XBMC setup again!

Please excuse my ignorance and forgive me if this is not posted in the correct thread / forum but I was wondering how far off this is from making it into the main official download for Live / Linux ?

Man I feel like such a n00b! Blush

i noticed that it really makes a BIG difference if the memory is in single or dual channel
same hardware (p5n7e-vm 4 gigs ram, 512 shared, ubuntu jaunty) gives me 49 dropped frames (and choppy playback and 19 or so fps) on killasampla in single channel, 7 (at the start) dropped frames and perfect playback in dual channel... i guess this problem doesn't exist with a dedicated video card, does it?
again, great work on vdpau, but i must second Birtybasset, isn't this mature enough to go to the main branch?


- nikiiv - 2009-03-01 21:20

One frame dropped in killa sample... single frame only!
Great job man


- pcjason - 2009-03-01 22:38

I just wanted to chime in and thank you for your hard work, motd2k. Now my lowly Sempron 3200+ (1.8GHz) coupled with a Nvidia 8200 based motherboard has no problem playing HD content!

As a hint to others, I was having a strange issue where there were a lot of frames being dropped and odd colors on the screen (lots of pink or green "trails" behind moving objects). The issue ended up being the powernow daemon. I guess it wasn't scaling the CPU power up quickly enough and was causing issues with the decoding. I didn't have the time to play with the powernowd configuration, so I just removed it and everything seems fine now!
