Video pauses for around 100ms after around 500ms of playback

SPECIFIC ISSUE ENCOUNTERED

While playing a video from device's storage the video stops for around 100ms at around 500ms playback time and then keeps playing normally. It doesn't matter if it's from the beginning of the video or after seek. First thought was that it was only the time that wasn't updated, but checked the video with my eyes, it actually stops. I've checked it many times, always similar values. Example log includes frames that video's time did not change:

07-02 11:55:38.975: W/Unity(15669): (time)=0 (bufferedPercentage)=19 (bufferedPosition)=1966 (state)=Buffering
07-02 11:55:38.991: W/Unity(15669): (time)=0 (bufferedPercentage)=19 (bufferedPosition)=1966 (state)=Buffering
07-02 11:55:39.007: W/Unity(15669): (time)=0 (bufferedPercentage)=36 (bufferedPosition)=3666 (state)=Buffering

HARDWARE/SOFTWARE VERSIONS

• Unity: 2018.3.7f1
• Google VR SDK for Unity: 1.200
• Device manufacturer, model, and O/S: Samsung Galaxy S7, PicoVR G2

STEPS TO REPRODUCE THE ISSUE

1. Create new GvrVideoPlayerTexture component
2. Set video url to file:///storage/emulated/0/test-video.mp4
3. Set video type to Other
4. Call Init, wait for VideoReady flag and call Play
5. Observe the video stopping for around 100ms after around 500ms of playback

Does this issue occur with the Big Buck Bunny video included in the SDK? Does this issue occur with the ExoPlayer sample player app?
