GeekBox is a Hackable Android and Linux TV Box Powered by Rockchip RK3368 SoC

There are many Android TV boxes on the market based on Rockchip RK3368 processor, while I’m not aware of any development board based on the latest Rockchip octa-core processor, and Linux support is basically inexistent. One device may fill both gaps: GeekBox. This TV box can run both Android and Ubuntu Linux, while it’s easily disassembled to access expansion headers. The hardware specifications are a little higher-end than most Rockchip RK3368 TV boxes we’ve seen so far: SoC – Rockchip RK3368 octa core Cortex A53 processor @ 1.2 GHz with PowerVR G6110 GPU System Memory – 2GB LPDDR3@1600Mbps Storage – 16GB Samsung eMMC v5.0 flash + micro SD slot Video Output / Display I/F HDMI 2.0 up to 4K @ 60Hz with CEC support Display + touchscreen headers Audio Output – HDMI Connectivity – Gigabit Ethernet, 802.11 a/b/g/n + 802.11ac 2×2 MIMO @ 867 Mbps (AP6354 module), Bluetooth 4.1 USB […]

Converting H.264 Videos to VP9 In Linux / Ubuntu

1080p videos are all good, but my Internet connection’s upload speed is limited to 512 Kbps, so for example uploading a 20 minutes H.264 video shot at 1080p30 may easily take 10 hours, even after some processing with Handbrake. So this week-end I investigated how I could reduce the upload size, and going with H.265 codec appeared to be a good idea at first. So I tried again H.265 encoding in Handbrake in Ubuntu 14.04, and discovered that adjusting CRF (constant quality factor) to 25 with H.265 was roughly equivalent to 20 with H.264, and both the compression ratio and encoding speed were greatly improved compared to default settings with a minor degradation in quality. If you happen to have a second generation Nvidia Maxwell graphics card you may want to check Nvidia Video Encoding SDK for speedier encoding. All was good until I decided to upload a test video, […]
