So, I realized this yesterday (I usually use Plex to cast stuff to my SmartTV, or just use a USB stick, so, haven't tried this before).
Most stuff when I want to cast, it starts the process and this is the error message I get on the TV:
I've tried different movies, tv show episodes, stuff that works through Plex and that I can watch if on a USB drive and JUST ONE OF THEM WORKED. It's a tv show ep, I have several of the same show, it's not the biggest file, it's not the smallest, it's not the biggest resolution or the smallest, I tried figuring out what the thing is and this is what I've been able to find:
The one TV ep that works has codec 1avc, and decoder hevc. All of the others mostly have h264.
Except there's one other file on my computer which works. It's a "music video", look, it works:
And look at the decoder on that one:
I'm really at a loss. I have an older HP laptop computer, Windows10 on it, I'd be willing to answer to any questions from anyone who's willing to help me solve this mistery :)
(Music mostly works, except for .flac. Photos work, I mean, they get cast on the big screen)
nice
