    Why is this listed as fixed? It is still an error for me in 5.4.0b21 Personal. I'm on Windows 10, using 64-bit unity.

    I get this both in 5.3.3f1 and 5.3.4f1, windows 10 using c#.
    2 errors:
    LoadMoveData got NULL! UnityEngine.WWW:get_movie()
    Cannot create FMOD::Sound instance for resource (null),
    Both points to MovieTexture movieTexture =;

    www.bytesDownloaded is same as movie size and www.error is null.
    I tried with ogg, ogv videos locally and also unity sample.ogg online. I can only see the first frame of the movie when the editor paused at the error.

    I am *still* experiencing this issue on 5.3.3p2, which mentions this being fixed.

    This is happening for our team in 5.3.4f1. (It's happening in an ogg video file with NO AUDIO, as indicated in previous comments.)

    As an extremely shitty work-around for the error
    LoadMoveData got NULL!

    WWW Class works in JS by copy pasting the example at:

    But even then it only loads ogg videos and not mp4, mov, etc.
