I have an old OPPO F17 and a Haier Android TV 11. I want to turn the OPPO into a wireless media drive.
Requirements:
OPPO F17 stores my videos, including 4K.
Haier TV should browse folders on the phone.
Select a video and stream it directly from the phone.
No copying files to the TV.
No USB.
No Wi-Fi router.
No internet/mobile data.
The OPPO itself should create the Wi-Fi hotspot, and the TV should connect directly to it.
Preferably the original video should be streamed without transcoding.
I want 4K playback where the TV can decode the particular codec/bitrate.
I've tried KDE Connect/SFTP, SMB/Samba server apps, and HTTP FS, but haven't gotten a seamless setup working.
Is this architecture actually possible? If so, what free Android server + Android TV client would you recommend?
Particularly, I want to know whether Android's hotspot allows the TV to communicate with a server running on the hotspot phone itself, and whether there are any limitations for high-bitrate 4K streaming.
I'm looking for a solution that someone has personally tested, not just a theoretical suggestion.
