Any known problem with K1-Pro and h264?

Hi,

My K1-Pro (S905d, with 4G ddr4) can play h265 with no problems, but it “ducks” when trying any HD in h264.

At every few seconds it starts junking the image for 5-10 seconds and then it’s good again, until the nest time.
Is there any special configuration to make it better?

Thanks for any hint.

Thank you Poida, for replying

I had the same problem with Kodi in Android, so I believe it’s not related to CE, but hardware.
Maybe the GPU (kali450)?
