The most obvious 'issue' from that log is that it is using software
decode. I couldn't find any detail on the video-pipe branch so I don't
know whether it should be using the gpu for decoding or not.

Other than that, there's little of note in the logs (using straight
'-v playback' would give a more useful log) and certainly no hint as
to why the peformance isn't great.
