- bobo1on1 - 2010-07-06 I'd use a 50 hertz mode instead of 25. - Goga777 - 2010-07-06 even for 50 field per seconds video or 25 frame per second you would like to use 50 Hertz ? Do you propose to remove mode "1920x1080_25" at all ? - bobo1on1 - 2010-07-06 50 hertz is fine for 25 fps and 50 fps video, but 25 hertz can only do 25 fps video. - Goga777 - 2010-07-06 but I suspected that with Code: Modes "1920x1080" "1920x1080_25" "1920x1080_24_0" "1920x1080_30" "1920x1080_60" for 25 fps video xbmc will choice "1920x1080_25" but for 50 fps video xbmc will choice "1920x1080" which mean "1920x1080_50p" - bobo1on1 - 2010-07-06 No, if 50 hertz is available it will always choose that for 25 fps. - Goga777 - 2010-07-06 thanks, I didn't aware about it. But let's come back to "1920x1080_50p" mode for 25 fps video. How xbmc will increase the fps from 25 fps (or 50 field per second) to 50 fps ? - davilla - 2010-07-06 Goga777 Wrote:thanks, I didn't aware about it. show the same frame twice 50 / 25 = 2.0000... also, stop thinking "fields per second" unless you are taking interlaced - Goga777 - 2010-07-06 And such idea also correct for interlaced video ? as far as know for video with 50 field per second need very powerfull deinterlacer (hardware or software) to do such job (50 fields per second ----> 50 frame per second), right ? what happened if vdpau graphic card doesn't have such performance or CPU is very slow ? - bobo1on1 - 2010-07-06 Goga777 Wrote:what happened if vdpau graphic card doesn't have such performance or CPU is very slow ?Then you're screwed. But this only happens on really slow hardware. Problems with a JVC DILA - wmilas - 2010-07-08 I have a JVC DILA I'm trying to get running with an ION chipset. I've having a bit of a problem. I have a whole slew of modes validate correctly: Code: (II) Jul 07 20:05:23 NVIDIA(0): --- Modes in ModePool for JVC ILAFPJ -- XT4 (DFP-1) --- But then when the it then adds the modes it doesnt add the the 60p or 24p modes: Code: (II) Jul 07 20:05:23 NVIDIA(0): Assigned Display Device: DFP-1 I'm at a loss as to why its doing this. No errors or anything? Help - trolly - 2010-07-08 Hi, I follow this guide with success, but i just miss something in part 4. export DISPLAY=:0; nvidia-settings -a "SyncToVBlank=1" -a "AllowFlipping=1" -a "FSAAAppControlled=1" -a "OpenGLImageSettings=3" -a "LogAniso=0" -a "GPUScaling[DFP-1]=1,1"; nvidia-settings -r On my config (9.10 x86, svn 31642, nvidia 256.35), when I launch the command manually (ssh) it work. But after a reboot, tv don't switch in the appropriate mode anymore. So I try to put the line in : /etc/profile /etc/bash.rc /home/user/bash.rc but it doesn't work (when I access with ssh it launch the command and xbmc work fine). Question is : Where can I put the command so it apply settings automatically at startup ? Thank you. Sorry, not my native languague. - JumJum - 2010-07-08 trolly Wrote:Hi, nvidia-settings requires a running Xorg to work.

I removed 25 herz mode and now I have Quote:Modes "1920x1080_50" "1920x1080_24_0" "1920x1080_30" "1920x1080_60" but xbmc reported 19:12:43 T:3032754048 M:159531008 INFO: ID:0x128 Name:1920x1080 Refresh:25.000000 Width:1920 Height:1080 why ? http://paste.ubuntu.com/460698/ - trolly - 2010-07-08 Quote:nvidia-settings requires a running Xorg to work. Try with "DISPLAY=:0; nvidia-settings -l" in ~/.xinitrc Don't seems to work. I create a ~/.xinitrc file with the line but xbmc don't start anymore. So I try to put it in /etc/X11/xinit/xinitrc, /etc/X11/Xsession don't work either. The only thing that work is to start a ssh session from another pc and launch Quote:export DISPLAY=:0; nvidia-settings -a "SyncToVBlank=1" -a "AllowFlipping=1" -a "FSAAAppControlled=1" -a "OpenGLImageSettings=3" -a "LogAniso=0" -a "GPUScaling[DFP-0]=1,1"; nvidia-settings -r. Can't find the right place to add this. But I have to find it cause the result is like the topic says, perfect. - trolly - 2010-07-09 Don't know if it's clean, but it works. 1. Set $DISPLAY variable export $DISPLAY=:0 in /etc/environnement 2. Create a file called 56nvidia-settings i, /etc/X11/Xsession.d/ which execute nvidia-settings -l Quote:# loads nvidia-settings config |
