Sunchip_CX-R9_SpecificationsAs previously mentioned one downside of RK3229 SoC is that it only supports Android 4.4.2, against similarly priced competitor like Amlogic S905. However, it is one of the rare platforms, actually the only I know of baring software decode, that supports 10-bit H.264, so you should be able to play the many anime videos distributed with that codec. VP9 support at up to 4K @ 30 Hz if also an advantage against S905, and Rockchip also claims faster video start time, and higher bitrate support up to 200+ Mbps. I’ve noticed Amlogic S905 cannot play one of my video sample at 120 Mbps smoothly, so this would definitely be an advantage for RK3229, although I’m not sure there are that many 100+ Mbps videos.

Sunchip CX-R9 should become available in February, and it currently sells for $32 for 1k orders.

Very interesting indeed. I hope the decoder would work properly most of the time.

I got the MX PLUS II model with this CX-R9 board…4K HEVC/h.264 10-bit decoding as well as h.264 Hi10 (anime) indeed works nice and smooth (250 mbps HEVC files as well) but only in MX player (HW decode) and in-built player and NOT in Kodi – h.264 FHD only), however HW de-interlace is of discard-field type so no smooth motion with video content (sports, TV channels) and it doesn’t convert BT.2020 to Rec709 colorspace as advertised… If anyone from Rockchip or Sunchip are viewing this: proper de-interlace and BT.2020 conversion or/and BT.2020 metadata passthrough via HDMI, please!!! HDR conversion to… Read more »
