Wangzhao, Did you try official Crosswalk build instead of your own build? From your description, it is not looks like codec issue, Crosswalk for Android use native video player, so I do not think you need build by enabling proprietary codecs.
Thanks, Halton.

The problem is that when playing HTML5 video, MP4 format video can be played normally in fullscreen mode. I got black screen in non-fullscreen mode. But WebM format video can be played normally both in fullscreen and non-fullscreen mode. I can't figure out the reason of this problem. What't more, I find https://github.com/crosswalk-project/crosswalk-website/wiki/Enable-MultiMedia-in-Crosswalk<https://github.com/crosswalk-project/crosswalk-website/wiki/Enable-Mu%20ltiMedia-in-Crosswalk> in Github. Does this have something to do with my video problem. I tried Enabling proprietary codecs but it doesn't works. I really need help. Thanks in advance. wangzhao.
