Roku Jellyfin Client playback Issues

[google007]

I am running Jellyfin 10.10.7 on Linuxmint 21.3 
The box is a HP z220 SFF:
Intel® Core™ i7-3770 CPU @ 3.40GHz
14GB Ram DDR3
GPU Intel Arc A310
Storage :
4TB Sata Media
512G SSD OS

Unable to play certain mp4/mkv files on Roku client but play fine on browser window.

Have ran ffmpeg encoding on some large personal video files and converted them using h264 compression, one file played but the others refused.

I will attach a screenshot of the message, along with Jellfin and ffmpeg logs.

I noticed I am able to play the files if I switch off HW acceleration but the buffering is terrrible.

And this playing locally.
