Why cannot play video after package

i have create /Content/Movies,put in my .wmv video and create mediaplayer && mediatexture && material,in editor,the video play work well,but after package my project,it can’t work,my material is black,i try package setting additional asset movies directory to cook,i try delete my c++ code [if(myVideoPlayer!=nullptr)] ,but did’t crash,it mean my code works but no useful,i try shipping development package but still can’t play,please give me the reason.
by the way,i use the 4.10 github version,maybe use epic launcher version can works well?

This was a known and reported issue UE-28011 in 4.10.4 and has been fixed in the 4.11.2 engine release.

Let me know if you have further questions or need additional assistance.
