    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.

    Can this issue be opened again once it's closed or do we have to submit a new one?

    Multi-threading was already disabled problem still exists. im using Unity 2018.3, VideoPlayer keeps stuttering every 2 seconds, stopping and going, both video and audio on android keeps stopping, its not usable at all, not even a little bit.

    Its as if something is hogging the CPU, or network get stuck and nothing to play for a second, but the game scene has nothing in there except the VideoPlayer and the player itself.

    Other video players work fine on the same video, but they dont have AudioSource like the Unity VideoPlayer does, i need the AudioSource, or else i would have dropped this player long ago.

    Is Unity Company ok with having VideoPlayer that doesnt work on Android when so many developers out there making android apps? So many complaints (including mine) cant be wrong!

    Right now im stuck because player dont work!

    PLEASE FIX!!!!!!!

    This still a problem on powerful Android devices and Unity 2018.4.12f1. Stop doing nothing and fix the freaking bug, come on!

    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.

    I think I am seeing this problem with 2018.1. What did you do to fix the issue?

    Ok, nevermind my comment from yesterday. Got it working and it wasn't the cause of the multithreaded rendering. Sorry for the wrong comment :)
