    Our developer has identified the issue is caused by Multithreaded Rendering option enabled. Disabling it may be a workaround for you until we get a proper fix.

    This problem exists even in Unity 2019.1.

    I have fixed this opening the project with Unity 2018.2.2.1f1 and transcoding the vídeo (was working even without the transcode, the problem is with some Unity versions).

    this is still a bug over two years later, despite tons of people chiming in to say dont mark it as fixed.... the fucking unity devs just mark it as fix and move on.. fucking scam

    I was experiencing the same issue in Unity 2018.2.0f2 and was able to fix the issue by changing the settings of the video file (I was using an mp4 file). The settings I used were as follows:

    Override for Android ✓

    Transcode ✓
    Dimensions Original (330x1018)
    Codec H264
    Bitrate Mode High
    Spatial Quality High Spatial Quality

    Still an issue in 2018.2.13 Verified on several android devices. Disabling multi-threaded rendering will allow the videos to play smoothly, but enabling it causes the stutter.
