I have a new LG 4k OLED TV, so I tried MEZZMO streaming with some 4K MP4 video files that used to work fine on my SONY 4K TV.
The LG recognizes the MEZZMO server and streams photos in 4K flawlessly.
However, my 4K videos of late are taken with a Samsung Note 8 and result in MP4 files.
The LG TV immediately tells me their format is not recognized.

Is there something I need to do within MEZZMO other than pre-transcoding for the LG TV? Everything works without error in MEZZMO, and the files stream via my SONY BD Player.

Thanks.
