2. Run application
3. Click open camera
4. Start record a video

Apparently, this error corresponds to [an encoding problem](https://developer.android.com/reference/androidx/camera/video/VideoRecordEvent.Finalize#ERROR_ENCODING_FAILED()).

I ran your example and found an error in the logcat:

Not sure yet why this happens, I'll investigate a bit more.

Sometimes, The video output can not be played by video_player plugin. I can not replicate this issue. I don't remember exactly the error message but it relates to video codec. Not sure if it relates to this issue

[apalala-dev]

After some tries, I believe that the issues arise when there's a video player in the widget tree. I think it works until there is a video recorded. Once one is recorded, it's loaded into the main.dart screen and that's when video recording stop working with this strange error. I commented the part that show the videos and I can't reproduce the bug anymore, even when recording several videos. Is it the same for you ?

[cvphat]

Is it the same for you ?

Yes, When I remove video player out the widget tree. The issue is not happened

[apalala-dev]

My guess is that the same codec is used for the video player and then for the video recording but can't handle both at the same time. Not sure what we can do to help. I would suggest to try to remove the video player from your widget tree before recording a video, and once it's done show again the video player.

Yeah, I think I have a way to workaround. Thank you

[apalala-dev]

Closing since there is a workaround.
