Stutter when using HW acceleration

[cosmoxl]

Seems like koying has fixed hardware accelerated playback on the Fire TV with his "aml fixes" for Kodi 17.
And from fritsch's comment here http://forum.kodi.tv/showthread.php?tid ... pid2453127 I hope it is getting included in MrMC soon.

Any comments to that. I'm on software decoding since beginning...cause of stuttering. Tested the nightly from 8th nov. of Kodi 17 and its working perfectly there.

for me surface had problems with display switching. but mediacodec (not surface) works great with switching to 24p. have you tried that?
I do have passthrough disabled.

I see same drops issues under kodi-20161112-ae37dd6-master-armeabi-v7a.apk which lead me to think there are pts issues with TVheadend. Amet uses TVheadend. Maybe he can comment more.

Just a bit strange that these clips play perfectly on the AppleTv. I did try SPMC on the firetv and it has the same issue.

I have an old PC with Windows Media Center on it. I record a clip on that and see if it has the same issues.

got out the big guns

It all boils down to arch. ATV4 is arm64, two core. AFTV2 is also arm64, four cores BUT we target arm32 as AFTV2 is actually both arm32/arm64. Called arm big.little arch. So when ffmpeg is used for decoding, arm32 side is used. Even with four cores, the AFTV2 is a little slower than Apples arm64, even with it's two cores. That Apple A8 has some real ponies...

I also tested Kodi/arm64 under sw decode and surprising it was much, much worse. They have screwed something up with deinterlacing on arm. bob-invert is not listed anymore so I bet it's using some monster cpu sucker. Much better if I turn off deinterlacing or set it to half (whatever that is Then I get results similar to ATV4.

Possible solutions are, target arm64 for AFTV4 but that raises distro issues. We would have to do two FireTV distros, one for arm32, the other for arm64.

Thanks for the comprehensive response!

I might be a little pessimistic, but it seems like I will never be able to use the firetv in place of the apple TV! I love the apple TV hardware, but the app selection sucks in the UK! Was hoping he firetv would be the box that did everything for me!

I would not discard the firetv just yet

I'll hold on to it then!
