Topic: SVP Lag & Crash

Sometimes, SVP playback starts lagging. If I reboot the computer, after the computer comes back, I get a message saying SVP ran into an error and it opens the LastErrorLog.txt, saying to post it on this forum. When the lag happens, clicking on the tray icon also causes SVP to crash.

I have only seen this problem on 1080p TV, it hasn't yet happened on my laptop display.

Here's the content of LastErrorLog.txt

Re: SVP Lag & Crash

It is not complete error log. I don't see any error there.

But I see that refresh rate of external display can't be detected correctly.

23:19:45.645; screen settings refinement: Display#00010001: 1920 x 1080 @ 59

must be something like that:

23:19:45.645; screen settings refinement: Display#00010001: 1920 x 1080 @ 59.94

Sometimes it happends. In this case you need to manually point right refresh rate.
Because of incorrect refresh rate you got incorrect smooth factor and output framerate.

23.974 * (22 : 9) = 58.603 fps
29.917 * (43 : 22) = 58.474 fps
2.586 * (23 : 1) = 59.478 fps
27.698 * (23 : 1) = 637.046 fps
29.954 * (41 : 21) = 58.482 fps

So big smooth coefficients lead to higher GPU load and to worse picture quality.
Right smooth formula must be:

29.954 * (2 : 1) = 59.908 fps

Re: SVP Lag & Crash

I'm not getting any specific error message, nor does the log contain any specific error message.

When rebooting, there was a process that wouldn't stop that had to be killed, related to video rendering (don't know the exact process name).

On the TV, there are 2 refresh modes available on Windows 8: 59hz or 60hz. Not sure what the difference is. When I put 60hz, however, whenever I switch between regular desktop and full screen, the screen flickers with "Video Mode Changed".

Re: SVP Lag & Crash

I'm getting to understand how the frame ratio is working. Videos are generally playing at a 2:1, 5:2 or 12:5 on my TV with current settings.

Something is causing the frame ratio calculation to go out of wack in certain cases.

With my background in programming, I can say that random bugs that can't be reproduced consistently are the worst kind.
