Smoothvideo ("Sync playback to display" feature) now merged in the mainline branch

**althekiller** · 2009-05-21 20:02

You guys need to realize that "smoothvideo" was just the name of the branch for development of greater control over how audio/video are synchronized. It's NOT the name of any setting or feature. Now that the facilities it added are in mainline, it's just some more settings to play with. Those settings have appropriate names to designate what it is that they do. Read the very first post in this thread for a detailed explanation of each.

Why not, from and end-user viewpoint, list the main option as 'Enable SmoothVideo' instead of 'Sync playback to display'. It just adds confusion when a feature is labeled one way on the forums, but the option is labeled differently in the application. I just think there should be some continuity.

Thanks for pointing out the startpost was written in an ancient northern dialect of Klingon.

Kaplah!

Here's a debug log from rev 20522:

lots of "CDVDPlayerAudio:: Discontinuty" in there... dunno if it's any use for debug though... Any more news on what could be the problem in Vista bobo?

Looks like it's working for you as there's none of these -

CVideoReferenceClock: Setup failed, falling back to QueryPerformanceCounter

Well the vista issue can be fixed by removing a call to SetForegroundWindow() but that breaks other stuff.

The log filled with discontinuities is a different issue, which we're currently investigating.

bobo1on1, do you have evidence of problems with audio synch still happening while resampling? It happened to me yesterday, but I was watching a TV episode with my wife and could not activate debug. I quit XBMC, restarted and it was back ok (resuming from where it left).

Hello developpers.

I use xbmc under debian testing with vdpau.

Since smoothvideo feature, i wanted to try it. Unfortunatly, if Sync Playback feature is enabled, i have Xorg crashing when starting a video.

NVidia drivers are: 185.18.04

xbmc SVN:20517

xbmc crash with :

Code:

Smoothvideo branch always gived me this result, and now linux branch is doing the same.

If it can help to debug. Need any other info to help solving this ?

Cheers.

If it happens you'll get a lot of discontinuity errors in the log.

You could try installing 185.18.10, but if Xorg crashes it's probably an issue with either Xorg or the nvidia drivers.

And that brings me to my next conclusion, this thread is getting filled up with issues that may or may not have been caused by the smoothvideo merge, but appeared around that time.
I'm prepared to investigate those issues or in the least provide some explanation of what is happening, but having them all in the same thread makes things very disorganized, therefore I'm locking this thread.

If you have an issue, start a thread on the forum or post a bug report on trac.
