Smoothvideo ("Sync playback to display" feature) now merged in the mainline branch
#76
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:
Thread 0xb25ffb90 (LWP 3661) exited]

Program received signal SIGSEGV, Segmentation fault.

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.
