I have the same error. But it seems to be video-dependent.
E.g. this video works fine https://file-examples-com.github.io/uploads/2017/04/file_example_MP4_480_1_5MG.mp4

amarchenko25 · 2021-05-17T12:29:27Z

Hi All,
have the same issue on iOS. Seems like an issue with video_thumbnail plugin. It cannot produce the last duration time thumbnail.
Do you have any progress?

char-lance-flamme · 2021-05-18T09:47:54Z

Hello,

@yoonjiyong @char-lance-flamme @amag2511 Have you added the proper permissions to the Info.plist file as stated here

Also, let me know which iOS version are you using.

Vitaly-V · 2021-05-21T07:53:05Z

Hi All,

@amag2511
I don't have any progress with it.

@sbis04

Device - iPhone 8
Softvare version - 14.4.2

As I mentioned above - with some videos it works cool, but with others, it returns the error.

sbis04 · 2021-05-21T08:53:15Z

@Vitaly-V can you provide some videos using which you are facing this issue? I will try to reproduce the error and then look into it.

char-lance-flamme · 2021-05-21T08:56:06Z

@sbis04
It is my Info.plist

Guys, any updates?

I also experience the same problem. Here are more details in case they can help:

Thanks. Happy to provide more details if it helps.

sbis04 · 2021-06-17T16:25:45Z

@Gicminos I see that the above screenshot is from an iOS Simulator, so did you try it on a physical device? Also, did you try with any different video to check if the error persists in that as well?

Vitaly-V · 2021-06-18T08:04:33Z

@sbis04, on the real devices' error looks pretty the same.
Yes, it's video dependent, - some videos are trimming well, some with this error.

sbis04 · 2021-06-18T08:06:27Z

@Vitaly-V Can you please share a video file or it's link which is producing this error?

Vitaly-V · 2021-06-18T08:36:21Z

@sbis04, please try this video file.

https://user-images.githubusercontent.com/4039270/122532393-1f29c600-d029-11eb-9289-7ead7b4f3c99.mp4

Vitaly-V · 2021-06-18T09:04:38Z

Or this one
https://user-images.githubusercontent.com/4039270/122536481-3e2a5700-d02d-11eb-8d19-5604ea96654f.mp4

Gicminos · 2021-06-18T09:11:32Z

I confirm what Vitaly-V is saying. The error on the real device is the same (while on release mode you see the gray band instead of the red error) and it is yes video dependant.

Gicminos · 2021-06-30T15:57:36Z

This PR #112 seems to be claiming to fix this error. Happy to test it myself in the next days, but will probably have to fork it and test it with just a cherry-pick of 82898fa because I am not sure about the other changes.

sbis04 · 2021-07-01T10:04:48Z

Try using the latest version of the plugin:

video_trimmer: ^0.5.2

Let me know if the thumbnail error is fixed.

Gicminos · 2021-07-05T23:07:15Z

We haven't tested widely yet, but we do indeed see improvements. I will let you know in case of any issues. Thanks!

sbis04 · 2021-07-23T05:40:44Z

Closing this issue. Feel free to open, if the issue still persists.

I have the same error

sbis04 · 2021-12-09T12:58:27Z

@BanidAzin @nisargdoshi is the error occurring with all the videos? On which platform are you testing (Android/iOS)?

BanidAzin · 2021-12-10T04:40:19Z

@BanidAzin @nisargdoshi is the error occurring with all the videos? On which platform are you testing (Android/iOS)?

@sbis04 Yes, it's happening for me all the time. I am trying to create a thumbnail after capturing a video using the camera.
I am testing it on iOS.

ovib · 2022-07-20T15:09:04Z

Any progress on this issue? I have the same error on iPhone SE second gen with iOS 15.1

charlieforward9 · 2022-10-20T19:34:40Z

I am also getting this issue. It does not prevent me from trimming the video, but it does result in a not-so-ideal UX. Looking forward to updates on this. I am testing on a real device iOS (15)

Gicminos mentioned this issue Jun 12, 2021

On Android when we do trim in Release mode App crashes. On IOS the trimmer thumbnail bar has red part with errors also cannot trim in IOS #110
