immich [BUG] Exif metadata 'Rotation: 180' ignored for videos on mobile app

The bug

Videos recorded in horizontal by turning the phone 90 degrees clockwise (how a left-handed would typically record the video with one hand) are reproduced upside down in the mobile app.

At least with my phone, the raw data of the videos is the same no matter the orientation of recording, except for the exif metadata Rotation, that would be 0, 90 or 180 depending on the case.

Videos with 0, 90 (even 270) values are reproduced correctly, only 180 is buggy.

The thumbnail (web browser and mobile app), reproduction in the web browser and preview in the web browser are all displayed correctly for all videos.

Reproduction steps

Prepare videos with different rotations. For example, download test video and set Rotation values with exiftool:

$ wget -O 0.mp4 https://freetestdata.com/wp-content/uploads/2022/02/Free_Test_Data_1MB_MP4.mp4
$ cp 0.mp4 90.mp4 
$ cp 0.mp4 180.mp4
$ cp 0.mp4 270.mp4
$ exiftool -Rotation=90 90.mp4
$ exiftool -Rotation=180 180.mp4
$ exiftool -Rotation=270 270.mp4
$ exiftool -Rotation *.mp4
======== 0.mp4
Rotation                        : 0
======== 180.mp4
Rotation                        : 180
======== 270.mp4
Rotation                        : 270
======== 90.mp4
Rotation                        : 90

Play the videos in the mobile app (Android), after uploading them to the server or before backing-up, makes no difference.

@jrasm91 I think this is more of a https://github.com/immich-app/immich/labels/%F0%9F%93%B1mobile related issue.

Actually, it seems to be derived from flutter and the video_player package: https://github.com/flutter/flutter/issues/122276. Is pinning video_player to version 2.3.4 an option? At least until https://github.com/flutter/flutter/issues/122276 is resolved.

Possibly resolved by #2908? Might need some adjustment to the transcoder too.

Noticed that problem too, seems like player problem. Immich Web and other web/mobile players play such videos correctly.

I also have this problem on the Android mobile app. Rotation 0 and 90 play correctly but 180 is upside down. When viewing on a web browser it plays correctly.

Issue still exists on latest version. @uhthomas yes, it's specific to android app. Videos are rotated upside down only on mobile app, look normal on web page. I'm left handed and all my videos recorded using phone are upside down in Immich android app.
