@hdmkv or mirror88,

What do you think of the results of CNX software about playback :


I do not know if they made tests with the latest FW 1.2.3

4K videos results in ZDMC:

HD.Club-4K-Chimei-inn-60mbps.mp4 (4K H.264 @ 30 fps, MPEG4-AAC audio) – Not smooth [Update: Realtek RTD1295 is limited to 4K H.264 @ 24 fps]
Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265 @ 30 fps – No audio) – OK
big_buck_bunny_4k_H264_30fps.mp4 (H.264 @ 30 fps – MPEG1/2 and AC3 audio) – Not smooth [Update: Realtek RTD1295 is limited to 4K H.264 @ 24 fps]
BT.2020.20140602.ts (H.265 Rec.2020 compliant – AAC audio) – Not smooth
Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (H.265 @ 60 fps – AC3) – Not smooth
MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC @ 24 fps – no audio) – OK
Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps) – Not smooth*
暗流涌动-4K.mp4 (4K 10-bit H.264 video) – Many artifacts, and slow decoding due to software decode, but fully expected since RTD1295 does not support 10-bit h.264
Tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps) – Not smooth, audio delays and artifacts*

-------------------

But maybe the internal player “Media Center” is better at playing videos, and some people even explained how to create a Kodi to Media Center wrapper to play videos. 4K video playback results with “Media Center” app:

HD.Club-4K-Chimei-inn-60mbps.mp4 (4K H.264 @ 30 fps, MPEG4-AAC audio) – Not smooth
Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265 @ 30 fps – No audio) – OK
big_buck_bunny_4k_H264_30fps.mp4 (H.264 @ 30 fps – MPEG1/2 and AC3 audio) – Watchable but not perfect (some frame drops)
BT.2020.20140602.ts (H.265 Rec.2020 compliant – AAC audio) – Not smooth and no audio
Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (H.265 @ 60 fps – AC3) – OK
MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC @ 24 fps – no audio) – OK
Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm – Watchable but not perfect (not 100% smooth)
Tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps) – Not smooth
That’s some improvement but still not perfect, and I was expecting better 4K video support. Hopefully most of the issue will be fixed before I complete the full review.
