I'm having some trouble with the AC3 Transcode. It's happening on a a new ASRock N3150-ITX motherboard.

My audio is going to a Sonos Playbar, which doesn't support DTS. I've enable my SPDIF as passthrough device and set yes to the AC3 capability and AC3 transcoding.
Whenever the transcoding is selected (which is required for 5.0 sound), the audio 'cracks' very loudly about every second. It's not always happening right at the beginning of the video, but it will come after a couple of seconds. This does not happen when the AC3 transcode is turned off (AC3 passthrough kept on).

CPU usage during ac3 transcoding enable video is around 10% per core (out of 4), 300 kb/s io load.
I have tried all the options in the first post, even up/downgrading to the kernel 4.1.6.

fritsch,

now all is ok for videos up to1080p. they are displayed at 1080p.

But 3840*2160@24p are displayed at 4096x2160 and not at 3840*2160.
And with sintel 4096x1744 I have the known problem but one other thing I see : sintel 4096x1744 is displayed at 4096x2160 so original size ( no need of rescaling ) but it seems that the video scaling is enabled. Should it be enabled in this case ? because with lanczos method -> lots of skips and drops.

Here the log when I try that : http://www.xbmclogs.com/poawuz43k

Can you also please get me the kodi-xrandr output again? The mode it is setting are not shown in your log from yesterday.

Did I need to set something else ?

I found my bug! Damn.

[fab67]

I see this in the log :

13:15:59 T:139852372367104 DEBUG: CRenderManager::Configure - change configuration. 4096x1744. display: 4095x1744. framerate: 24.00. format: VAAPI

Why display: 4095x1744

[fritsch]

Why: Your pixel ratio is not 1.0 it is 0.97 something -> i workaround that and ignore it, cause it's just one pixel off.

Will post a new build in some minutes.

That will spam the log, quite curious.

I am totally buffled how std::abs can produce -1280 ... but never the less, this might be some OE ccache issue ...

Here is another version, this should actually work :-)

Thanks for testing, btw: http://fritsch.fruehberger.net/OpenELEC-...e69d8e.tar

Edit: Argh (wait 3 minutes to download, here is the md5sum: e0f59efbb90dea67c10786ba08f8f7ea I pressed the reply button too early, before upload was finished).

Edit: Online now btw. can you join IRC - it's a bit boring :-)
