Android: vertical videos (tall native aspect ratio) are displayed incorrectly

[sunweiyang]

I'm seeing this for both the default react-native-video (Android’s MediaPlayer API) and react-native-video-exoplayer (even with PR #842 -- I still see this issue).

For tall native aspect ratio videos (height > width, .mp4 files in my case), Android seems to transform my video (height becomes width, width becomes height, pixels are remapped to look like it's rotated). This happens with all resizeMode settings and all style sizes (I happen to have a full screen component in my screenshots, but it consistently happens regardless of component sizes).

This library works perfectly fine for wide native aspect ratio videos (width > height).

Some more background: this issue happens for an emulator of Android API 26 (Pixel).
It worked for the one physical Android device I have, which is Android API 24 (Samsung Galaxy S6).

Any chance you can provide a video that doesn't work. I've tested:

and it's working properly on an API 26 emulator.

We recently updated from ExoPlayer 2.4.0 to 2.7.3 and before merging a fix, I want to make sure there's still a problem. Plus I need to test to make sure the fix works :)

Looks like it works now with the latest exoplayer -- thank you!

This is not working with 4.4.5
