[Video Player] Large videos with H264 codec don't play on iOS devices




Priority: 7Not yet prioritized for a release


Severity: 3Secondary functionality broken

When Transcoding is enabled and Codec set to H264 for a large video file, the Video Player component will not play it on iOS devices.

Steps to reproduce:
1) Open the attached project.
2) Open 'Main Scene'.
3) Build for iOS.
4) Run on a device.

A video is set to override plane's material and should play on startup. However, the video doesn't start playing; no audio is playing as well.
This does not occur with VP8 codec. Other Video Player targets also have this issue (Render Texture, Camera Planes).

Reproduced on:
2017.1.0b1, 5.6.0f3

    Replicated in 2017.3.0b7 and 2017.2.0b11. Only on Android, and switching to VP8 did not solve the issue. iOS worked fine.
