    You are thinking correctly. USB2 will choke those drives quite effectively.

      Well I have one, running a TVHeadend server as I type this, and I assure you it is completely true.

      As a matter of fact, the C1 and the C2 have vastly better video decode hardware than any of the Rpi boards. The C1 does H.264/H.265/VC1 decode at 1080p. The C2 adds HDMI 2 and a better video decode engine that will do 4K at 60 Hz. The C1 can encode H.264 at 1080p30 while the C2 can do 1080p60.
      I am unaware of any system demonstrating this. Are you perhaps referring to an Android OS?

        I ran the Linux version of Kodi (OpenElec) on my C1 and played back 1080p H.265 files with full hardware decode.

        Video encode is exposed through the nvenc library in ffmpeg.

          Because the code in question was hand-coded into Kodi. It uses the AmLogic VPU's NEON instructions. This code has not been ported to other programs, or especially the underlying libraries like libx264 or gstreamer.

          Perhaps you want to read up on what nvenc is. It is a library for special hardware included on Kepler-and-newer GPU cards, That hardware is not included on the Mali 450.

          The only hardware on the C1 capable of doing hardware encode is the AmLogic VPU. In spite of much effort, no one has got this working. Using current ffmpeg with libx264 results in encode rates on the order of 10 FPS on my machine. But don't take my word for it:



          When you get realtime straight-through h264 transcoding working on your C1+, let me know and I'll be happy to try it on mine. If you think I'm wrong, go to the Odroid forums and ask for yourself. Until then, please stop spreading inaccurate information.
