Seeking backwards in VideoPlayer video takes considerably more time than seeking forwards

Video

-

-

Priority: 3Not yet prioritized for a release

-

Severity: 3Secondary functionality broken

Steps to reproduce:
1. Open user attached project "VideoPerformance.zip"
2. Build for android device
3. Press "High profile" video
4. Seek forwards, it should take a second or two to calculate and show video at the selected time
5. Seek backwards, it should take much more time to calculate and show video
6. Seeking to start is instant

Expected: Seeking forwards or backwards should be optimized better and in general it should take about the same amount of time
Actual: Seeking forwards seems to be easier than seeking backwards

Reproduced on: 2017.1.p2, 2017.2.0f1, 5.6.3p3

    Since I have started to play videos in my new iPod touch, it has started to give up with some ipod touch problems which I have tried to solve using https://applesupportnumber.net/blog/ipod-touch-5th-generation-issues/. But I would like to know why did such kind of error occur?

    I had the same issue on 2017.3.0f3 and Android (iOS works fine), and after trying a lot of things, what worked for me was to go to the end of the video (videoPlayer.time = clip.length), wait 1 sec, play the video, wait 1 sec, and then advance to the "rewind" position previously stored.
    Without the waits, it just do the same error, "pause" the video and then play it after a couple of seconds/minutes

    Fix confirmed:
    float currentTime = (float)videoPlayer.time;
    if (_time > currentTime)
    videoPlayer.Pause();
    else {
    videoPlayer.Stop();
    }

    videoStatusText.text = "LOADING";
    videoPlayer.time = _time;
    videoPlayer.Play();

    We have found a way to workaround this bug , we restart the url when we want to seek backwards , so the "backwards" is converted to "forwards" ; Another way is you can prepare two videoplayer , that can convert the "backwards" to "forwards" , too.
    , by Sam and Rw from China, we hope this idea can help you.
