Okay makes sense.

I see that:

core_freq == GPU core frequency - makes sense to overclock that

h264_freq == Hardware video frequency - guess it needs to be in sync with the core_freq?

over_voltage == Due to overclocking the above?

Good to know popcornmix.

Where exactly do I add those lines to setup that? I assume it'll be on a file somewhere?

If the CPU would then be considered the bottleneck - why do I not see 100% cpu usage when playing back that video in question !?

Hi Popcornmix - thank you.

LybsterKodi - the problem is, it doesn't matter what I do to the audio delay setting - it almost has no effect. Very strange.

At this point I cant use Kodi for the purpose I need it to.

Could this simply be gtrying to watch 1080P videos on a Raspberry pi 2 is not really going to work?

hi,

So tried this out and it made no difference.

I am starting to think by comparing playback on a Windows PC against Kodi, that the problem is that the video is actually playing slower and the audio is actually at the correct speed.

None of these options have made any difference and the audio delay settings don't help because it is the video which seemingly is around 3 seconds slower than the audio (comparing the time taken to view the video to a specific recognised scene).

Has anyone seen this before? Looking at top it doesn't look like the pi is overly stressed in terms of cpu or memory?

Hi chewitt!

I love the idea of this --- will give it a whirl.

Hi all.

I am a brand new users of Kodi, and Libreelec - thanks for such a great bit of software.

I installed it on an (admittedly) underpowered Raspberry Pi 2 Model B and configured *nothing* from the installed 10.0.0.2 version.

I have a couple of videos on my USB and one of them works *perfectly*. The other is a better quality video and I am finding that the audio is quite far ahead of the actual video playback. I have done some research and note that there is a 'audio delay' slider on the playback of the video which can be adjusted - but the experience of this is fiddely and ideally shouldn't be required.

Then there is an advancedsettings.xml people have been discussing where you can set a default for all videos, however my concern is that this 'delay' is different on every movie and therefore a big problem.

I don't see why this is an issue on kodi - where I can play the same files on a mac or a windows PC without doing anything and the audio and video is in sync perfectly (clearly this isn't a video file based issue, more something on the method of playback)

Is there any settings anywhere I should try flicking before I get into manually altering this delay on a video by video basis (which I likely won't do as its too much of a pain)?

Thanks once again!
