[WebGL] Video Player updates to a previously sought frame when seeking a paused video

--

-

Reproduction steps:
1. Open the “IN13187_VideoSeek“ project
2. Open the “SampleScene” scene
3. Build And Run using WebGL
4. Click to play the video
5. Click to pause the video
6. Click “Seek Halfway”

Expected result: Video frame changes
Actual result: Video frame doesn’t change

Reproduced in: 2021.3.8f1, 2022.1.13f1, 2022.2.0b5, 2023.1.0a6
Could not test in: 2020.3.38f1 (python errors)

Reproduced on: macOS Monterey 12.0.1

Notes:
1. Not reproduced in Play mode
2. “Seek Beginning” seems to work fine

Also: appears to be specific to Chrome. Safari works fine.

  1. Resolution Note (fix version 2023.1):

    Clearing cached timestamp of previous texture update when seek completes to force texture update at the next occasion. Some browsers (Chrome) don't change the timestamp when seek settles, leading to missed updates.
