React-native: Black screen for HTML5 video player in Android WebView

[mehcode]

Description

1. Created new project

react-native init webview_example

1. Replaced text nodes with:

        <WebView
          javaScriptEnabled={true}
          style={{flex: 1}}
          source={{uri: `https://www.youtube.com/embed/IPV3rQtctkM`}}
        />

1. Run.

2. Video does not show (only black screen) but audio does play fine

Reproduction

Full source code is https://github.com/mehcode/rn-scratchpad/blob/master/index.android.js

Solution

I have no idea. I've been poking it for awhile.

Additional Information

• React Native version: 0.40.0
• Platform: Android v7
• Operating System: Linux

Some more information. That example works 100% in Android <= 6. The bug seems to only exist in Android 7+. There must be a difference to WebView usage that we're not handling.

Another update. I've reduced this bug down to just raw android and have the same behavior.

@mehcode I have the exact same problem on Android Nexus 5 emulator. The embedded video only has audio. Do you have any solution now?

I just gave up and use react-native-video

Did the original problem occur in the emulator and on actual device as well? (hint: maybe emulator only?, second hint, make sure you haven't disabled hardware acceleration accidentally).
