[Mac] VideoPlayer lags for a few frames after the first loop when Loop and Audio Track are enabled
How to reproduce:
1. Open attached 'project-1174907.zip' project
2. Enter Play mode
3. Wait till the video loops for the first time and observe the second loop
Expected result: Video does not lag
Actual result: Video lags for a few frames after the first loop (and all the following loops)
Reproducible with: 2017.4.31f1, 2018.4.6f1, 2019.1.14f1, 2019.2.1f1, 2019.3.0a12
Notes:
1) Does not reproduce when the audio track is disabled
2) Could not reproduce this behaviour with any other video
3) Reproducible on all render modes
4) Turning off 'Skip On Drop' does not make any difference

Resolution Note:
Won't fix due to Apple's AVPlayer limitations. Performing a seek of a video when there is an audio track enabled has a delay due to the AVPlayer waiting for the audio track to catch up.
Workarounds: To achieve a seamless looping video with audio, ensure the video has a constant frame rate. Set the Audio Output Mode to None in the Video Player and play the audio track through an Audio Source component instead.
