slow switching times from sd to hd and vice versa on an Apple TV 4k #114

Hi guys,

some time ago I changed my Kodi client from an Nvidia Shield Android TV to an Apple TV 4k. On the Nvidia Shield I had really good switching times, like with all my kodi client hardware I ever had, regardless of switching between sd or hd.

But with the experimental Kodi version 17.6 with vnsiclient 2.6.25 for the Apple TV 4k from Memphiz, vdr 2.2.0 from the Debian Stretch repo and latest vnsiserver from GitHub I have slow (5 to 10 seconds) switching times while switching from an sd to an hd channel or vice versa. Switching between sd channels or switching between hd channels works as flawless within 1 or 2 seconds as I was used to with the Nvidia Shield and all my other clients (Windows 10, LibreELEC).

This issue is not related to latest vsniserver. It also happens with latest vnsiserver version 1.5.1 in the Debian Stretch repo and also with version 1.6.0 from GitHub.

While updating the vnsiserver from v1.6.0 to v1.7.0 tonight, the issue was solved for the current kodi session. I did the following:

At this stage I had normal switching times (1 to 2 seconds) while switching between sd and hd or vice versa. After that I stopped kodi, restarted it and the slow switching times were back.

Kodi 17.6 for the Apple TV 4k is highly experimental and at the moment there is no kodi 18 for testing.

Any thing we can do here? If so, which information do you need to have look at the issue?

Thanks and regards Hoppel

Ok, played a bit around. Activated a tvheadend docker, to see that it has the same problems. It's also the same with MrMC (Kodi fork) and VDR/TVHeadend.

But I recognized that it's much better without hardware acceleration activated at the Apple TV 4k.

So it's not a vdr/vnsi problem at all.

Thanks and regards Hoppel

why do you waste money on crap like Apple TV? For the same price you can get a much better system.

hw decoder on Apple devices won't decode interlaced material. Hence useless for tv anyway.

OK, this is your opinion.

I have a really big Apple endpoint park here at home: Two iPhones, an iPad, two Apple Watches, a MacBook Pro, a Homebridge Integration for my FHEM House Automation and since a while an Apple TV 4k.

The Integration is great, everything works together really flawless. Siri gets better and better.

The Apple TV 4k is the only endpoint at the moment which does frame rate switching for all the apps from the Apple AppStore like Netflix, Amazon Prime and also Youtube (?). I know these Apps will arrive as Kodi addons with InputStream under Kodi 18 and frame rate switching won't be a problem with these addons mostly regardless of the underlying endpoint plattform. At least it worked with my Nvidia Shield,(AndroidTV) but that device doesn't integrate into my complete home environment as well as the Apple TV 4k. At the moment Kodi 18 is still unstable and until these Apps and InputStream work stable with Kodi I don't see the possibility to use something else.

The Kodi 17 app from Memphiz, which is considered very experimental, also works really flawless. The only issue I have is this thing with pvr.

Yes I bought a developer account from Apple to get Kodi to work, but it's worth the money in my opinion. ;)

I do most of my development on a MacBook Pro. I also have an iPad and an iPhone. I know how those things work and would never ever use one of those devices as my primary box for watching tv. Android is even worse.

OK, I think you as a developer have another point of view.

The Nvidia Shield is working very good in combination with Kodi. The problem with the Nvidia Shield is the miss of automatic frame rate switching for Google PlayStore Apps like Netflix or Amazon Prime. Frame rate switching only works fine with Kodi. But you need Kodi 18 for these addons, which is unstable. It's the circle of hell. :)

Until Kodi 18 gets stable, boxes with LibreElec or CoreElec are not an option for me. Even if Kodi 18 gets stable, you have the danger to loose functionality of these kodi addons because of api changes by the streaming providers.

Do you use any of these streaming services? Which platform do you use for your daily Kodi TV?

Do you use any of these streaming services?

I have an Amazon Prime account.

Which platform do you use for your daily Kodi TV?

I have an Intel system running Ubuntu with fluxbox as window manager. Means I run Kodi on X11 which I consider reference platform for video player.
