    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 issue is still present in unity 2019.3.
    Also there are apparently bots posting spam in the comment of this issue tracker - all of this doesn't come across as serious

    Still an issue:
    Samsung Galaxy S5e
    Unity 2019.2.6f1

    But works fine with:
    Samsung Galaxy S3

    Multi-threading was already disabled.

    Tried but did not work another solution, setting the mp4 videos to these settings:

    Override for Android ✓

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

    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 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).
