View Full Version : Adjust refresh rate - New Video Player setting?
Just got SVN version 19205 and I noticed there's is a new option in the Video Player settings that wasn't there before called 'Adjust refresh rate'.

What does it do exactly?

It adjusts the refresh rate of the screen to match the video. Perhaps the string needs to be extended with:
"of screen to match the video"

According to what logic? How does it adjust the refresh rate?
Based on refresh of video being played.
Oh, and I believe only on Linux. Elupus, correct me if I am wrong.
Based on refresh of video being played.Ok, but I'm sorry to repeat myself... according to what logic.
If a movie has 23.976 fps and you have a 48Hz display refresh rate available, will XBMC pick that? If you have just 60Hz, what will it do?
Oh, and I believe only on Linux. Elupus, correct me if I am wrong.
That would explain why I don't see any difference in FPS between it being On or Off then.

It doesn't alter dinamically the frame rate as Reclock does, it simply picks the refresh rate closest to the frame rate, if I'm not mistaken.
Still, sad to see it only on Linux, for now. My experiments with Ubuntu ended up less than successfully.
Nothing on this http://xbmc.org/trac/ticket/5307 unfortunately. :sniffle:

If you want the logic, read the code:
// Find closest refresh rate
for (int i = (int)CUSTOM; i<(CUSTOM+g_videoConfig.GetNumberOfResolutions()) ; i++)
{
RESOLUTION_INFO &curr = g_settings.m_ResInfo[m_iResolution];
RESOLUTION_INFO &info = g_settings.m_ResInfo[i];
if (info.iWidth != curr.iWidth
|| info.iHeight != curr.iHeight)
continue;
int c_weight = (int)(1000 * fmodf(curr.fRefreshRate, fps) / curr.fRefreshRate);
int i_weight = (int)(1000 * fmodf(info.fRefreshRate, fps) / info.fRefreshRate);
// Closer the better, prefer higher refresh rate if the same
if ((i_weight < c_weight)
|| (i_weight == c_weight && info.fRefreshRate > curr.fRefreshRate))
m_iResolution = (RESOLUTION)i;
}
fps is the input framerate.

Added in r16196 with some modifications to make sure it selects 59.94 instead of 29.97 for 23,97 clips.
That proves it's not yet working for Windows for me - any idea when it will be?

When someone does code to:
1. Get the refresh rate of the current video mode.
2. Set the refresh rate of the current video mode.
As far as I am aware, this is not possible through SDL, so we'd have to use some other method.
Cheers,

Is this the same thing as 'shearing' ?
I have the Atlantis 8.10 final and even though I have my settings set to:
(Vertical Blank Sync always enabled)
I still get tearing in my movies.
Can I fix this somehow?

try a newer build
I am using the build from here:
http://downloads.sourceforge.net/xbmc/XBMC_for_Windows-8.10.exe?use_mirror=
(the newest build?)
or is there a newer build than this?
yes
look in the forum stickies
reading is fun-dum-mental :P

Tried it, same problem :p
fingers crossed, i hope this works out for the windows release
Is there any way to check current refresh rate while playing a movie?
That stats involed by the "o" key on the keyboard doesn't provide this info (would be great)
I think we're reaching a consensus in another thread about how resolution and framerate switching should work and be stored internally, so this will come after that is nailed down.
For my own information though: folks which want adjusting of refresh rate, I'm assuming your display device is a television over DVI/HDMI right? What kind of options show up in the windows display resolution dialog? I mean do you get 1280x720@24, 1280x720@30, and 1280x720@60 etc?

Just an FYI here, sometime the info retrieved from the Monitor is just pain wrong. It's a big problem under the Linux world so this is an area where one has to program defensively. Just something to think about..

The screen refresh rate isn't shown anywhere but it can be added to the "Video Mode Info" display, the one shown when you cycle zoom modes if you patch thuslyIndex: xbmc/GUIWindowFullScreen.cpp

I'll add it now :)
WOW, Guys, that was fast :D
Thank you!!
edit:
However, If I upgrade to the latest SVN version on Live (using the svn repo), I only get SVN:16188, which doesn't include this feature... What am I doing wrong?

I mean do you get 1280x720@24, 1280x720@30, and 1280x720@60 etc?I connect through VGA and I created custom resolutions for 1366x768@24, 1366x768@48, 1366x768@50 and 1366x768@60 in Nvidia control panel.

Good question. It went in in r16241, are you on the right branch? Try running svn info in the top level directory and make sure the url is https://xbmc.svn.sourceforge.net/svnroot/xbmc/branches/linuxport/XBMC
Unless I'm missing something about what you mean by "Live" ???
And thanks ashlar, I dragged my TV into my office and hooked it up and I'm trying to get some other resolutions and refreshes to it for testing. ATI's CCC seems to only want to give me 60Hz on it though. Damn you ATI, you will do what I desire!
You are using the repo. Use svn instead and build yourself.
The repo is only a nightly thing I believe.
Can this be done on XBMC Live?
I don't have found any info on this. And it seems the standard Linux build instructions are removed (if it at all would be applicable)
Thanks!
