Please test this file to see if ZDMC playback is smooth with 4k HEVC 10bit Astra-SES_Demo_UHD_satellite_end-of-2015.ts This can be downloaded from : http://demo-uhd3d.com/files/uhd4k/Astra-SES_Demo_UHD_satellite_end-of-2015.mkv 1. at startup playback should be smooth without frames : buildings, birds and no tearing and shutter. 2. next sky should be smooth 3. at 00:55 - antenna should move smooth. 4. at 01:43 - plane and building movement should be smooth Next file : Astra.SES.Demo.HEVC.ts 1. at 0:30 train movement should be smooth. I tested these files on Nvidia Shield tv with 16.1 kodi and is smooth. I tested these files on Zidoo X1 II and: - startup playack for first file is no smooth, is shuttering - not OK - antena movement is OK - plane building movement is no so smooth but low shuttering Next file : 0:30 - train movement is smooth. VP9 30fps and 60fps are decoded ok, and playback is smooth on nvidia shield (amc-vp9 codec is used) On zidoo X1 II ff-vp9 is used for both 30fps and 60fps. I expected that for 30fps rockchip codec to be used, since this device and this chip support VP9 30fps.
