Remuxing

[vosa]

I have couple videos in MKV with anamorphic pixels, with aspect ratio specified on MKV container level (16:9). While playing those files in web chrome browser, remuxing kicks in and Im loosing the AR information resulting in deformed video. How come Edge can play MKV without remuxing in the first place, its basically fork of chrome, isnt it? Anyways I would expect the remuxer to read the AR info and apply it in remuxing process. Is there any settings for remuxing to allow that? If not, Im not sure whether classify this as a bug or feature request. Thanks!

Hi,
I'm encountering the same problem. In the mkv-file the values are PixelWidth=720, PixelHeight=576, DisplayWidth=1024, DisplayHeight=576, DisplayUnit=Default(0). The underlying MPEG2 Video file also seems to have set the AspectRatio=16:9. When I play the video with VLC the DisplayWidth and DisplayHeight seem to be taken into account since the aspect ratio changes when I change those values, but when I stream it with Jellyfin the aspect ratio isn't right. The logs show that the transcoding with ffmpeg produces an output video with 704x576 resolution. The problem occurs with the webplayer and also the internal player on the android app.

Edit:
Just realized it's transcoding not remuxing for me, but I think the problem is similar enough.
