Hi same issue here with oculus quest 2.
I have issues with only 3D movies. And I tried a lot of movies... (encoded by good teams that know what they do 😉 )
This is clearly a bug, this is not a bad aspect ratio encoded in the video container I guess.
I used MKVToolNix v56.1.0 ,the display width and height is specified as full HD dimension
Video Stereo Mode is not set.
Using MKVToolNix Gui v56.1.0 I tried (with the "header editor tab):
- to change the Video Display Width to 3840 => No change in DeoVR (VLC display video correctly : 3840x1080)
- to set the Video Stereo Mode to value 1 (which mean SBS, Left eye first) => No change
- to change Video Pixel Width to 860 (which makes VLC to make display longer, not shorter) => no change
- the three ! => no change
Each time the video appears in format 8/9
(so the szakinorbert88's is wrong...) setting 3840 does not fix anything
BigScreen seems to take into account only the change of pixel width, but by taking the half of the left image, and the right of the right image => making the result totally unwatchable lol...
For all others it just always display 16/9...
Please fix this bug !
