Can't do that with the standard xbmc dvdplayer

The tearing on WinXP has made this unusable since and I don't get the sense that there's any urgency to fixing it. I hate to be coarse here, but I finally got around to giving the latest build a try on my main rig, thinking that maybe the laptop I've been testing dsplayer on just wasn't up to snuff, but my main rig suffers from horrendous tearing too.

For the record - specs are:

WinXP x86 SP3
ATI Radeon HD3200 (onboard 780G chipset)
Catalyst 9.10

I don't have *any* tearing whatsoever with 28016 or earlier, but *every* build since then has had this problem. So can you PLEASE either revert the renderer, *OR* can you give us the plain old OVERLAY mixer as an alternative? I have no idea why people insist on using VMR9 - it's shit and has no benefit over Overlay, since overlay can do DXVA and subs too and overlay *never* has issues with tearing.

Please

Cheers
The REAL Joe

on WinXP SP3, Ati HD 3200/780G. Never knew what I could do against it. I blame 780G chipset, its much praised but has a lot of flaws.

zilexa Wrote:Here is an example of tearing. Found it via internet, its a game but same thing. It's when the screen 'image' isn't rendered (or whatever you call it) fast enough, you get lines as if the picture is cut.

As far as I understand, VSync or Vertical Synchronisation will prevent any form of tearing, but will take slightly longer for the image to build, so maybe this could cause audio delay when not applied correctly.
I didn't try this option in XBMC yet.

Also I read about people that change the refresh rate (Hz) to the exact frame rate of the video they are currently watching. It is suppose to be a (better?) solution. But that seems a VERY dumb thing to do for me, since video frame rate is VERY low compared to your screens frame rate (60Hz or higher). Any lower might cause headache/flickering screen. But I am not an expert on this part, might be wrong here.

>>X<<' Wrote:No wonder you have tearing on everything if your not using vsync



When you run the same refresh rate as frame rate it doesn't mean your screen runs at that rate you screen will run at a multiple of that rate, so when you run at 24Hz screens normally run at 72Hz (24Hz x 3)

Edit: Just tried Rev29334 on XP and didn't have any problems enabling vsync from within XBMC but even with it off I could still over ride it in my GPU control panel, if you check the screenshot your see top vsync enable using xbmc so refresh rate matches my screen, bottom its off so out of sync with my screens refresh rate all over the place hence you get tearing

Problem I get with this realease is high cpu even with avi (xvids)

For me, with Nvidia 8400GS PCI using driver 196.21 (Windows XP SP3), instead of getting 60 hz like you got on the first screen shot, I am getting refresh rate fluctuating between 55 to 58 hz with vsync on, and 62hz + w/ vsync off.

>>X<<' Wrote:Don't use that as the sole indication that vsync is working I only posted that because there's quite a difference with mine, if I start in full screen mine hovers around 55 as well but I still don't have tearing, its only stable around 59-60 if I switch to full screen from windowed which I hadn't noticed until now

If you have tearing then vsync probably isn't working as I don't know of any other reason for tearing

zilexa Wrote:hmm ok will test that out. Thanks for explaining the difference between screen refresh rate. Now I finally understand!

But than whats the deal with some people being addicted to ReClock, when XBMC can already adjust refresh rate to fps?

more ontopic: will install the latest build and test.
