Video Playback Issues
#1
Good day,

Just curious as to why when I playback a movie on my laptop using xbmc the movie is playing in a fastforward type speed but when i hook it up via hdmi to my receiver the video playback is perfect on my projector?

Any ideas?

Thanks

What device have you set in XBMC -> Settings -> System -> Audio Output Device, when just viewing on the laptop?

Sounds like your two display sources have different resolution and refresh rates.

Well, that's probably the problem. That's a real non standard resolution for an HDTV. I know you're not using a TV, it's your laptop.

Did you try setting your laptop's display to 1280 x 720?

Loads of laptops use 1366 x 768 these days. This is a popular resolution for "HD Ready" TVs so I suspect there are lots of cheap 1366 x 768 LCD panels around. I'd be very surprised if this was causing the video to play back fast.

I don't recall seeing this problem before and it is a wierd one. Can you supply a debug log? Enable debug logging from System settings, System, Debugging, and restart XBMC. Wait a minute or two to let all the startup tasks finish then play a video that runs at high speed for a minute. Close XBMC.

Open the debug log by pressing Windows-R and in the Run dialog type:

"%appdata%\xbmc\xbmc.log"

(including the quotes). Click OK and the log should open in Notepad. Copy and paste the log into http://pastebin.com/ and post the link it gives you here.

k i think i found the issue. i shut the Allow Hardware Acceleration (DXVA2) to off position and played back the movie. The movie played back at normal speed but now with a jutter. like the movie couldn't catch up... Could it be my video card? Using a Dell I3, 8gig ram and a GT 420 video card.

thanks again.

Hardware acceleration doesn't work properly with Intel GPUs, though this is the first time someone has reported that the video runs fast. The problem with turning the hardware acceleration off is that your CPU may not be powerful enough to decode video without it.

You could try using a nightly build from http://mirrors.xbmc.org/nightlies/win32/ as I believe these have improved Intel support.

Pardon my ignorance but I don't have the slightest clue what to do with the previous link that was posted. Any ideas?

If you open http://mirrors.xbmc.org/nightlies/win32/ you'll get a list of files looking like XBMCSetup-20111010-34f799e-master.exe etc. These are installers for the development versions of XBMC that will soon turn into v11.0 Eden.

If you click on a file and select Run this will install a development version of XBMC. I believe the development versions have improved support for Intel video cards.

However you may want to wait a bit as the beta test for v11.0 is about to start.

Excellent thanks for the info. I could wait for the new version as it's not killing me at all. I'm watching all films on the projector and not off my computer.
