VideoView draws black line at bottom

Question

I have a problem, I have a ViewPager with fragments and I have a VideoFragment that displays a video. Everything works fine but if the video is loaded and starts playing it displays a small black line at the bottom of the View I think.

See screenshot for reference !

Here is some code, I have absolutely no idea where the bar comes from....

My Fragment Layout :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/grey_900">

    <com.pr0.pr0.library.CircleProgressBar
        android:id="@+id/progressVideo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/grey_900"
        android:layout_centerInParent="true"
        app:mlpb_show_arrow="true"
        app:mlpb_enable_circle_background="false"
        app:mlpb_arrow_height="5dp"
        app:mlpb_arrow_width="10dp"
        app:mlpb_progress_color="@android:color/holo_red_light"
        android:visibility="visible"/>

    <com.pr0.pr0.view.CustomVideoView
        android:id="@+id/videoView"
        android:layout_width="1px"
        android:layout_height="1px"
        android:layout_centerInParent="true"/>

Dominik，我遇到了同样的问题，所以我决定使用另一个视频，但黑线消失了。我使用了宽度和高度都更大的视频...（本质上更大的视频）
