Update from Kodi 15.2 - Fast Forward Issue
#1
Hello,
i have been used OpenElec since March 2016 on a Raspberry 3b. With Kodi 15.2. 
Overall, it went very well. 

I have now a brand new Raspberry Pi 3b+. Finally with Gbit LAN. So i have reinstalled all to get a updated system.
I have  buyed a mpeg License. It is Enabled.
I have installed the newest Libreelec 8.2.4 with Kodi 17.6.
I have also tested with the newest Beta (7.4.2018 with Kodi 18) without changes in the issue. Also i have tested with Openelec without changes in the issue.

I use Kodi to Record Live TV to watch later. (With TVHeadend). I use an external HDD on the USB Port. 

I have issues with Fast Forward. I use it to watch Motor Race (Formula1) in Fast Mode. So I do not miss anything. Skip is no option, if i skip 30 seconds, i miss for example pit stops.
I have made two Videos.
Openelec with Kodi 15.2 (32x with good refresh rate)

Libreelec 8.2.4 (Kodi 17.6) with 16x (Standard Settings with Aeon Nox Skin. I did not find Fast Forward Mode on Estuary).

I have posted before in libreelec Forum. But this is not a Libreelec problem. I think it is a general problem on the Raspberry?

I have now found out that 
Disabling "Allow hardware acceleration - OMXPlayer"
(This is the standard setting in LE) (Same settings as in my Videos).
It will not work smooth. It has a bad refresh rate. 

Enabling "Allow hardware acceleration - OMXPlayer" 
FastForward will not work. After a few seconds the Video freeze. Sometimes the Raspberry crashes but often the Video starts from the freezepoint. 

Disabling "Allow hardware acceleration - MMAL"
The CPU load increases highly. But my Raspberry has no Problem (even with HD Movies)
FastForward will be work very good!

I have read several posts about the problem. But have not found a solution. Mostly is the answer: "Use Skip". But this is no option to me.

Is there a chance to get Hardware Decode work with Fast Forward? What is different from Kodi 15? 
What can i do to help out with this problem?

Can you post a sample video (not a video of you fast forwarding, but upload the actual video file you are fast forwarding through). It only needs to be a few minutes long, maybe 5 minutes.

Hello,
the Sample Video is here:

It happens on all my Video Files. I have also tested a DVD (it is unencryptet and copied to HDD). With hardware acceleration FastForward stumble without hardware acceleration FastForward will run smooth.

Thanks for your help!
