[xwiki-users] Error html5: Video file not found

Hi all. I try to add video (.avi) on the xwiki page (xwiki 2.7. Oooops :)) and getting "html5: Video file not found". The code of this page: {{video videoURL="https://somehost/xwiki/bin/download/Project_disp/video1/%D0%9F%D0%BE%D0%B8%D..." videoWidth="720" videoHeight="576"/}} Any ideas?
