View Full Version : Adjust refresh rate *before* playback start
Since TVs take some time switching refresh rate, it would be good if XBMC could switch refresh rate before playback starts.
As it is, currently, I lose a couple of seconds of video with a Pioneer Kuro LX6090.
Is this something doable? MediaPortal achieves it through mediainfo.dll, I don't know if XBMC gets its video info through the same approach.

I think in principle it could be done, but one problem is the frame rate reported may not necessarily be in agreement with the actual refresh rate that should be used (eg some 30fps stuff should be played at 24fps and vice-versa). Also, refresh rate can change throughout the video.
Still, it's not a bad idea if it can be done reliably. I believe elupus had some reservations - perhaps he'll jump in with his comments.
Cheers,

Idea... I'd like to have the GUI stay in the same refresh rate as last video played. Currently having to have to wait for reconfiguring the screen and amplifier (hdmi passed through) is annoying. Of course GUI is not as smooth in 24 fps but I rather have that then the long pause I see now. Would make going in and out of videos much faster since refresh rate might already be correct
ultrabrutal, I currently decided to keep 24Hz as default resolution for the same reason.

now if only audio (LPCM7.1) would do the same, my amp would stop clicking when going on/off plus missing the first second or so

I've experienced the same problem as ashlar. Usually with short streaming clips i miss the most important part of the video :(
I've disabled the refresh rate switching for this reason. An option to enable a delay before playing the video in the advancesettings.xml would be the best solution for this problem. I reckon every display needs some time to adjust to the switch. My samsung takes about 1 second to adjust, but every display is different so it should be configurable IMO.
I know, I know(Patch Welcome ;) ) wish i had some time.
I created the ticket for this: http://xbmc.org/trac/ticket/6914
Just thought of bumping this, seeing as the current situation with refresh rate/resolutions/auto switching, etc. is in such a mess (not a criticism, mind, it's been announced and everything, I know :)), that the developers will surely be looking at these portions of code anyway.
Hope it wasn't a bad idea. :)
