[Mac] Video player jumps to keyframe when calling Play() if paused before a keyframe

Video

-

Reproduction steps:
1. Open user's attached project and scene "SampleScene"
2. In Game View, enable Maximize On Play and enter Play Mode
3. Press "Seek near keyframe"
4. Observe frame number
5. Press "Play"
6. Observe frame number

Expected result: The video continues to play without skipping any frames
Actual result: The video skips to frame 300

Reproducible with: 2019.4.9f1, 2020.1.3f1, 2020.2.0a21
Could not test with: 2018.4.26f1 (console errors break project)

Note: On Windows, when the buttons are pressed, the frames do not match. When manually set to match, the issue still does not reproduce.

  1. Resolution Note (fix version 2021.1):

    Fixed in 2021.1.0a4. There was logic to tolerate a .5s skip-ahead when rate is changing. But when the original rate is 0 (meaning playback is paused), this skip-ahead should not happen.

  2. Resolution Note (fix version 2020.2):

    There was logic to tolerate a .5s skip-ahead when rate is changing. But when the original rate is 0 (meaning playback is paused), this skip-ahead should not happen.

  3. Resolution Note (fix version 2020.1):

    Fixed in 2020.1.13f1. There was logic to tolerate a .5s skip-ahead when rate is changing. But when the original rate is 0 (meaning playback is paused), this skip-ahead should not happen.

  4. Resolution Note (fix version 2019.4):

    There was logic to tolerate a .5s skip-ahead when rate is changing. But when the original rate is 0 (meaning playback is paused), this skip-ahead should not happen.

    This issue also affects iOS. It doesn't seem to affect Android.
