Hopefully this is the right kind of question for this community, my apologies if not.
I’m looking for some sort of device that will let me load my own media from a USB / SD card, and play it to my TV. Does such a device exist? Some sort of remote controlled box that can just load mp4 / mkv files from locally hosted storage? I have been using my PC over HDMI but it can get annoying having an awkward room layout because my computer always has to be next to the TV to do this.
a small PC with kodi can do this. It can do much more as well.
This was the answer for me. A mini PC with linux, kodi, and the kore app installed on my phone
Or a raspberry pi
There are a lot of tiny PCs these days that can output 4k video and audio. Look for something with an N100 or N200 CPU if you want to go as cheap as possible, they tend to be super-cheap and perform well. I’ve got one of the GMTecs and this wireless keyboard+mouse, works really well from the couch.
There are cheaper/other options but to get you started: https://www.amazon.com/GMKtec-Windows-Computer-Business-G3-dp-B0CQ4XQ2WG/dp/B0CQ4XQ2WG https://morefine.com/collections/pc-box (specifically the M9)
My solution is a bit old school: A raspberry pi connected to my network and running miniDLNA. It has an externally powered USB hard drive. My TV runs Android and I have VLC installed. Any DLNA client works including Xbox and mobile phone apps too.
I don’t think mini DLNA is even updated anymore so eventually my solution might stop working but it’s been running solid for 10 years
Take a look at simple Android TV boxes with a USB port. There are plenty of options and you can just install vlc on them
My Roku tv has an app that streams from network shares and my Synology NAS.
Most TVs these days have a USB port for exactly this purpose, you can load media files up onto a flash drive and plug it in, then you should be able to browse the files and play it from there.
However, if you want to be able to play files hosted on your PC without having to copy them to a drive, you would have to set up a media server like Jellyfin on your PC and either buy or build a compatibility for your TV. Fire TV sticks or a Chromecast would work as cheap options to buy, or you could look into hosting a Kodi instance if you have spare hardware lying around.
There are really a ton of options, my above suggestions are only scratching the surface.
My TV is a dumb TV (for lack of a better name). It does have a USB port, but it only displays photos and can’t play external footage. I keep all of my downloaded media on an external HDD. I did look into the whole XBMC aka Kodi / jellyfin combo stuff for a bit.
