[macOS][iOS][tvOS] Video Player lags when Playback Speed is changed
To reproduce:
1. Download attached "VideoPlayer.zip" project and open in Unity
2. Open "SmapleScene" scene
3. Enter to Play mode
4. Change Video Playback Speed
Expected result: Video speed changes without any issues
Actual result: When Video speed is changed there is a Lag (approx. 0.1 - 0.5 s) in Playback
Notes:
- This issue happens only on macOS, iOS, and tvOS
- This issue does not reproduce on Windows
- Could not check on Unity 2018.2 and older because the project becomes corrupted
Reproduced on Unity 2018.3.0a1, 2018.3.14f1, 2018.4.4f1, 2019.1.9f1, 2019.2.0b9 and 2019.3.0a9

Resolution Note (fix version 2020.2):
The hiccup happening on speed change when playing sources without active audio tracks has been removed. However, hiccups when changing speed beyond 2x multiples, or when playing sources with audio tracks, is inherent to the Apple playback engine so will remain.
