-

How to reproduce:

# Open the user’s attached “NewVideoPlayer-TestProject-master” project
# Build and Run all the Scenes on Android
# Switch to the “Far Plane” Scene in Player
# Skip to the “VP8_HD_1080p” video using the “Skip Forward” button
# Play the video

Expected result: Video starts without any glitching
Actual result: Video frame isn’t rendered for a second with sound glitching

Note: Higher the video resolution, higher the glitching time

  1. Resolution Note:

    Movie preparation is never instantaneous, but some devices perform it faster than others. Devices where this preparation is slower will have a perceptible delay when starting playback. The VideoPlayer has a few settings to take control of the wanted behaviour: callback when preparation is completed, allowing frames to be skipped or not in order to preserve sync with animations, etc. The nature of the video (resolution, frame rate, keyframe density) as well as the stability of the game's main loop all affect whether playback will be smooth. When facing such issues, reducing the video complexity is typically the solution.
