Bug Android crash when seting value in VideoPlayer.frame

I'm making a VideoPlayer UI that plays a video by streaming.
When setting the value in UnityEngine.VideoPlayer.frame to move to a specific frame of the video by implementing Time Control Slide UI, the application crashes with the following error.

This works fine on iOS. We've seen this happen on certain Android devices. (Samsung Galaxy Note 9 / Samsung Galaxy Fold 3, etc.)

Unity Version is 2020.3.38f1(LTS)

my code is like this

Code (CSharp):

1. // Silder UI Touch Event -----------------------------------------
2. public void OnPointerDown(PointerEventData e)
3. {
4.         if (seekCoroutine != null) {
5.             StopCoroutine(seekCoroutine);
6.             seekCoroutine = null;
7.         }
8.  
9.         dragging = true;
10.         videoPlayer.Pause();
11. }
12.  
13. public void OnPointerUp(PointerEventData e)
14. {
15.         float seekValue = GetComponent<Slider>().normalizedValue;
16.  
17.         Seek(seekValue);
18. }
19. // ----------------------------------------- Silder UI Touch Event
20.  
21. // Seek Function calling from UI Event -----------------------------------------
22. public void Seek(float seek)
23. {
24.     seekFrame = videoPlayer.frame = (long)(Mathf.Clamp01(seek) * videoPlayer.frameCount);
25. }
26.  
27. // VideoPlayer.seekComplete Action -----------------------------------------
28. void OnSeekComplete(VideoPlayer source)
29. {
30.         source.Play();
31. }
32.  

 

I have the same issue.
However, it does happen when I do use the VideoPlayer.Stop() function or when the videoPlayer is destroyed.

Tested on 5 devices, all Samsung.
- Crash on: Android 10 , Android 12 (x2)
- No issue on: Android 8 (x2)

Builds done on:
- 2 PC with version 2019.4.40f1, 2020.3.40f1, 2020.3.41f1, 2021.3.13f1, 2022.1.22f1
- 1 MAC: 2021 LTS

No crash when Target API level 30 -- Crash on API level 31 and 32

**Steps to reproduce**:
- Start new Project, 3d core template
- In the default scene, add a **VideoPlayer** + **raw image** + 2 buttons
- In project, create a render texture
- Link VideoPlayer target texture to raw image
- Link render texture to raw image
- Use a basic script to prepare movie + 2 functions to be linked to button (VideoPlayer.Play(), VideoPlayer.Stop()) + url (https://www.abc.com/movie.mp4)
- Build Android with the target api level set to 31 (or 32)
Will crash when button Stop pressed.

I did try:
- VideoPlayer.Pause() before VideoPlayer.Stop()
- Set VideoPlayer.frame to 0
- Set VideoPlayer.targetTexture to null,
- adding delay (wait next frame, wait a few seconds after "unloading steps")
- Different Videos from different host. (all mp4)
- Seem ok for on device file

 

@The_Island @leadhouse have the same issue.
Videoplayer works fine in 2021.3.11f1 but in next version 2021.3.12f1 it is broken, atleast Stop and Destroy are broken which make the Videoplayer fully unusable.
Only tested the latest 2022.1.22f1 where it was broken also as mentioned, guess it broke around the same time or earlier.

did anyone create an issue about this ?

 

Same problem here !
Unity 2021.2.5f1 work just fine but 2021.3.12(LTS) cannot handle the Stop() on video from URL (crash app on Android build with android target API 31).

- Every build with android target API 30 or less works (video can be stopped)

 

@The_Island I haven't .. btw VideoPlayer crashes on Android 11 (API 30) when target version is API 33 using Unity 2021.3.12f1 or 2021.3.13f1 (or 2022.1.22f1)

 

Same problem here with Unity 2021.3.15f1, the video crashes the app 1/2 seconds after stopping it

 

same here, 2021.3.14f1 + android target 33. Any update/plans for a fix?

 

Yes, the developers have made a page in the tracker. https://issuetracker.unity3d.com/is...g-the-source-url-of-a-video-player-in-android
