Video Player is broken on some Kindle Fire devices

Video

-

Steps to reproduce:
1. Open attached project "VideoError.zip"
2. Run and build for specified device
3. Video Player will be either broken entirely or laggy

Expected: VideoPlayer Starts playback after finishing the prepare coroutine.
Actual: Video player glitches out and doesn't play or plays video but lags on newer Unity versions

Reproduced on: 2018.1.0a6 (laggy), 2017.3.0b11 (laggy), 2017.2.0p3 (laggy), 2017.2.0f3 (glitches out), 2017.1.2p3 (laggy), 5.6.4p3 (laggy)

Devices Under Test:

Amazon KFFOWI (Fire (2015))*, OS:5.1.1, CPU:armeabi-v7a, GPU:Mali-450 MP, Build:Amazon/full_ford/ford:5.1.1/LVY48F/37.5.9.5_user_595457220:user/release-keys

Amazon KFTT (Kindle Fire HD 7" (2012))*, OS:4.0.3, CPU:armeabi-v7a, GPU:PowerVR SGX 540, Build:Android/tate/tate:4.0.3/IML74K/7.5.1_user_5174320:user/release-keys (Doesn't play video at all) / (unsupported OS API 15, video player requires at least API 16)

Notes: Check the different repro videos. The Glitch happens on 2017.2.0f3, the laggy videos on every other version.

Resolution (by design): malformed video file, encoded with variable frame rate, old android devices are unable to extract expected frame rate from video meta data, and results playing in frame rate approximated from timestamp difference between first two frames.

    We are having this issue too in much newer kindle fire devices (models of 2018)

    Most of the times the video doesn't play at all.

    We use EXACTLY the same code in all platforms (other Android devices, iOS devices, webgl, macosx ) and the videos are playing as expected.

    What is wrong with kindle fire tablets?
