After playback about 30sec, CPU usage becomes high (a full core) and then frame dropping starts. This happens on Nightly39.0a1 as well as on Firefox36. And also this happens on Google Chrome40.

you may need reload the page to continue playback if prompted a something special player download on the video. This problem also happens on Presto Opera12.17.
